Information literacy is an essential skill in the 21st century. This skill is required for students to find, select, evaluate, and use information they have gathered effectively. The implementation of a specific learning model aids students in developing their information literacy. One of the learning models expected to enhance students’ information literacy is the Reading Concept Mapping-Think, Talk, Write (Remap-TTW). This study aimed to discover the effects of the Remap-TTW learning model on students’ information literacy. This quasi-experiment study used a non-randomized control group pretest-posttest design. The study was carried out in the State Senior High School 1 Kencong, Jember, Indonesia, in the even semester of 2021/2022. The test instrument was in the form of an essay test. Students’ information literacy was measured using numerous indicators: determining the extent of information needed, accessing the needed information, evaluating information and its sources critically, using information effectively to accomplish a specific purpose, and accessing and using information ethically and legally. The scores were analyzed using the normality and homogeneity test, followed by One-Way ANCOVA. The analysis results showed a significance value of 0.000 (P-value < 0.05), signifying different information literacy between students attending learning with three different learning models. The obtained scores were considered significant, indicating that the learning model significantly influences students’ information literacy. Thus, Remap-TTW can be used as an alternative learning model to improve students’ information literacy.

Muhamad Wafda Jamil, Eni Nuraeni, Adi Rahmat — Fri, 26 Apr 2024 00:00:00 +0000

Quantitative literacy is an important skill for biology students. During COVID-19, students had to adapt to several changes, including shifting from offline to online classes. However, not all biology content can be taught easily, especially online. Therefore, students need self-efficacy abilities. Self-efficacy was important for students to be able to make a plan for their learning. This research aimed to describe students’ self-efficacy to continue their online biology learning during COVID-19, based on their quantitative literacy skills. This study used 20-item questionnaires with four choices of statements. The biology topic chosen was plant anatomy. This research measured the score of 82 first-year college students’ self-efficacy from three aspects - magnitude, strength, and generality. Data were analyzed using descriptive statistics to measure the mean, the highest, and the lowest students’ self-efficacy scores. The result showed that the average score of students’ self-efficacy was 2.72, which means students’ self-efficacy was in the moderate category. All three aspects were also in the moderate category, with the strength aspect score being the highest at 2.76 and the magnitude aspect score being the lowest at 2.66. Based on the number of participants’ level of self-efficacy, 3% of students were in the high category, 96% were in the moderate category, and 1% were in the low category. The result showed that most of the students in this research have a moderate level of self-efficacy in online biology learning, based on quantitative literacy. This means that most of the students still must develop their self-efficacy skills to learn online quantitative lessons in biology successfully. The results also suggested that it is essential to teach students how to manage their learning behavior through the development of self-efficacy to succeed in online quantitative lessons in biology learning in the future.

Iqlima Rahayu, Wiji ., Tuszie Widhiyanti, Sri Mulyani — Fri, 26 Apr 2024 00:00:00 +0000

This study aimed to analyze the misconceptions in the chemical concept of the factors that affect reaction rates through a qualitative descriptive method. The misconceptions experienced by students were examined through analyzing journals, books, and field experiences. Furthermore, research was carried out to obtain misconceptions that were often experienced by students and the sources of those misconceptions. There were 30 misconceptions about the factors that affect the reaction rate based on the literature. Based on the results of the study, there were three misconceptions experienced by 20 students from the total number of 21 students. The misconception that most students experienced was that when the concentration of reactants increases, a reaction will take longer because there will be much more particles to collide. In addition, the rate of the same reactions was compared at different temperatures, and then the reaction with the highest temperature was defined as the rate of reaction. The next misconception was that the temperature increase in an exothermic reaction can increase the forward rate and decrease the reverse rate because the equilibrium shifts to the right. Misconceptions were caused by information from the internet, teachers teaching in schools, textbooks used by students and the everyday life experiences of students.

Bringing Compassion to Mathematics Learning in Elementary School

Fri, 26 Apr 2024 00:00:00 +0000

Poor instructional design is alleged to be the cause of the low ability and poor mathematical attitude of students. The preparation of learning design focuses too much on academic intellectual barriers and tends to override psychological-emotional barriers. Without overcoming cognitive and emotional barriers at the same time, a student will not achieve optimal results in learning mathematics. This study aims to analyze the needs of learning mathematics in elementary schools and especially analyze the existence of social emotional barriers in learning mathematics. The results of the learning needs analysis are used as the basis for developing a more comprehensive mathematics learning design. This study uses a qualitative - descriptive method. The study was conducted in 10 elementary schools in East Java involving 30 students and 10 mathematics teachers. The results showed that students who had difficulty in learning mathematics were not always due to the student’s academic capacity, but were also influenced by their ability to focus, struggle, and their involvement in learning. The teachers so far only focus on overcoming academic obstacles and tend to override social emotional barriers in learning mathematics.

Mathematical disposition is a tendency to think and act in a positive way. Changes in learning activities due to Covid-19 have an impact on the learning environment. This study aims to obtain an overview between dispositions and mathematical performance in online learning, and the effect of disposition on the mathematical performance of high school students. This research is concerned with correlation and regression analysis that relates mathematical dispositions to mathematical performance on relation and function material. The research was conducted on 70 high school students from the city of Bandung. To analyze data related to correlation and regression, Pearson product-moment was used. The results of this study were as follows: 1) A significant positive correlation was observed between mathematical disposition scores (X), and mathematical performance scores (Y) with a correlation coefficient of r = 0.42, this means that r2 = 17.2%. The variation in students’ mathematical performance (Y) can be explained by the student’s mathematical disposition variable (X). 2) Based on the regression equation Y = 34.211 + 0.548X, this shows that because the X coefficient is 0.548 > 0 (positive) and significant, the mathematical disposition variable has a positive effect on mathematical performance in online learning.

Thinking is a cognitive activity that produces different ways of solving problems which affects numeracy literacy ability. The numeracy literacy consists of two domains, namely change and relationship and quantity. This study aimed to describe students’ numeracy literacy ability viewed by characteristics of students’ way of thinking. This study was a qualitative research with a phenomenological design. The participants were eight 9th grade students from a junior high school in Central Java, Indonesia, who had different characteristics, that are concrete sequential (CS), concrete random (CR), abstract sequential (AS), and abstract random (AR). The data were collected by using written tests, questionnaires, and interviews. The results show that each characteristic had its own way of solving the numeracy literacy problems. In quantity domain, CS, CR, and AR students tend to answer the problem with one solution; however, AS students responded with various alternative answers. In change and relationship domain, a difference was observed between concrete thinkers and abstract thinkers. CS and CR students tend to solve problems by using an example to take a trial-and-error approach. Meanwhile, AS and AR students tend to work using existing concepts by manipulating the formulas in the question with logical and rational processes.

Herizal ., Marhami ., Nurul Akmal — Fri, 26 Apr 2024 00:00:00 +0000

In mathematics, there are several methods for proving mathematical statements, two of them are direct method and indirect method. Both the methods were included in the mathematics curriculum at senior high school level as a learning topic. It implied that the teachers or pre-service teachers must master these methods. In addition, learning advanced mathematics courses also needed the ability of mathematical proving. The direct method was often used in proving mathematical statements. This descriptive qualitative study was conducted to examine what errors were written by the students in constructing mathematical proofs by direct method. Two basic problems (mathematical statements) were administered to 13 college students. They were pre-service mathematics teachers in one of the public universities in Aceh, Indonesia, and were asked to prove the statements by direct method. The data were analyzed by using Miles and Huberman step. The results showed that there were three main errors, (1) errors in using definition correctly, (2) errors in algebraic process, and (3) proving by examples. It concluded that the students must be accustomed to mathematical proving activities to avoid errors in constructing mathematical proofs.

In learning algebra, one of the skills needed to be acquired by students is solving equations, such as linear equations in one variable and quadratic equations. This study aims to analyze the symbol sense ability of students by investigating strategies used to solve algebraic equations that consist of linear, quadratic, and rational equations. A qualitative descriptive method was conducted. The instrument included a test with one linear equation, one quadratic equation, and three rational equations (involving linear or quadratic factors). The test was administered to 12 students from 12th-grade high school in Bandung. Each student was asked to solve it in two different ways of answers if possible. The results showed that students were able to use symbol sense strategies for solving problems. However, there were still mistakes in solving algebraic squared value concepts, affecting their final results of the answers. We conclude that even if students can use their symbol sense abilities properly, they need to pay attention to their mathematics concepts.

This study aims to describe the metacognitive self-management of students in developing rigorous mathematical thinking. This study uses a qualitative method with a case study approach. The participants were three students from the thirdlevel mathematics education department, who were selected and made a contract with for real analysis lectures. The first student experienced a significant change from the beginning of the meeting, resulting in the metacognitive self-management process being well-conditioned. He completed the task more confidently than the initial presentation, used several references and sources of information to complete the job, and represented each answer in the form of mathematical symbols. This studentscognitive function appears to be of level-1, with qualitative thinking. For the 2nd student, a change was observed in the learning process and the teacher’s motivation and guidance. The results of the interviews showed that the student applied strategies in completing assignments. He answered them systematically, based on experience, and mastered the prerequisite material. This student showed improved thinking skills related to mastery of concepts from new material, analyzing the problems given, being critical and focused when answering, and looking hard to get maximum evaluation results. This 2nd student entered the level of quantitative thinking with precision. Lastly, in the 3rd student, self-management seems stable, but was still lacking in adjusting the understanding of prerequisites with understanding concepts from new material. The development during the learning process shows that he can activate his mathematical knowledge, compose logical proofs of Real Analysis material problems, and build relationships between prerequisite concepts and new material. This type of student enters the level of abstract relational. The results of the study can be a reference for teachers to determine the learning model and the related instruments, so that they can grow the level of mathematical thinking before, during, and after the learning process.

Asep Irvan Irvani, Dian Agus — Fri, 26 Apr 2024 00:00:00 +0000

This study aimed to analyze student and teacher communication in discovery learning through transcript-based lesson analysis (TBLA). The research was conducted in one of the junior high schools in Garut Regency on science subjects. The learning material studied in this research was about Coulomb’s Law. The learning video was taken from one of the open class activities from a series of lesson study activities. As many as 16 students of grade 9 were included in the study. Through descriptive research methods, researchers revealed learning trajectories and student communication methods while learning through the transcripts made. Learning activities are divided into three main parts, namely introduction, core activities, and closing. There are five stages in the core activity, namely literacy activities, critical thinking, collaboration, communication, and creativity. The results of the analysis show that in the preliminary activity, communication is dominated by the teacher. The dialogue that appears is just a minimalistic dialogue. In core activities, student communication had started to dominate, especially at the collaboration and communication stages. The use of interactive simulation media at the collaboration stage improved the communication between students. The creativity stage was mostly dominated by the teacher, until the closing activity, and less by student communication. The lag time between teacher questions and student answers is the key to student responses. When the pause is given too quickly, there was no communication from students at almost all stages.

Improving Scientific Argumentation in University Students Through a Training Approach

Fri, 26 Apr 2024 00:00:00 +0000

The capacity to recognize formal arguments is crucial for clinical literacy. However, college students frequently lack a structural understanding of those arguments, in particular when the arguments are extra complicated. This study used an experimental method with a pre-post-check design. A follow-up of four weeks was used to research whether courses on figuring out the structural additives of casual arguments would enhance college students’ competence to recognize complicated arguments. The course was embedded in a constructivist mastering surroundings, and its content material was primarily based totally on Toulmin’s argument shape model, consistent with which arguments may be deconstructed into numerous purposeful additives: claims, datums, warrants, helping evidence, and rebuttals. Being capable of discovering warrants was primary to clinical literacy due to the fact warrants decide whether an end was justified primarily based totally on data. The effects display that schooling in argument shape typically no longer enhances overall recital for all college pupils and argument kinds, however, it’s miles beneficial for figuring out extra complicated arguments with much less specific systems and relational components among key additives (i.e. warrants). High-reaching college students gain maximum from this intervention, and it additionally enables college students with excessive pretest correctness scores. Our effects advocate that interferences to sell argumentation abilities need to be included in the curriculum, and those interventions need to be designed to shape the skill degree of learners.

A study related to the COVID-19 pandemic was carried out on high school students to assess students’ health literacy and determine related factors. Data collection was carried out from December 2021 to February 2022 by dividing urban areas, developing districts, and remote regions. The Health Literacy Questionnaire (HLQ) was adapted to suit the conditions of the COVID-19 pandemic. The data was interpreted as descriptive-narrative. Differences in literacy ability and the relationship with influencing factors were analyzed using ordinal regression and SEM-AMOS analysis. Limited health literacy was found in students from remote areas. A significant relationship was found between health literacy and class interest based on the ordinal regression test results. In contrast, health literacy was not related to gender, grade level, infected experience, and domicile. It was found that the ability to navigate health system information had a significant effect on students’ understanding of health literacy. Health literacy, which was low and unequal, is expected to improve strategic and sustainable education programs through science learning and physical health.

Fri, 26 Apr 2024 00:00:00 +0000

At school, students have studied the characteristics of waves and the relationship between period, frequency, wavelength, and the speed of propagation of transverse waves. However, students often experience misconceptions based on intuitive thinking and the phenomena they encountered. Thus, the research aims to describe the instrument validation of developing a multitier open-ended transverse wave instrument (MOTWI), which is useful in deeply assessing the misconceptions of high school students. The 4D (defining, designing, developing, and disseminating) model has been utilized as the method for developing the instrument. The participants were 67 high school students aged between 16 and 18 years (21 males namely “Mas” and 46 females namely “Mba”). The validity and reliability of MOTWI were analyzed using Rasch Model with MINISTEP 4.7.0.0 software. MOTWI validity from item dimensionality was valid. Cronbach Alpha (α) value was 0.75 (good category), and item reliability was a very good category. The construct validation results of MOTWI were valid and reliable for seven items. The students’ conceptions and misconceptions were analyzed with Wright maps. The conceptions of students were categorized as sound understanding (SU), partial understanding positive (PUP), partial understanding negative (PUN), no understanding (NU), misconception (MC), and no oding (NC). The misconceptions were mostly found in the characteristics and the factors that affect the speed of propagation of transverse waves. In conclusion, developing MOTWI can be used to assess and identify conceptions and misconceptions of students.

Mark Joseph F. Orillo, Voltaire M. Mistades — Fri, 26 Apr 2024 00:00:00 +0000

Using a mixed-method design, the study investigated the effect of the use of multiple representations on 207 (106 male and 101 female) Grade 11 students’ conceptual understanding and metacognitive awareness in learning concepts in physics (mechanics). There were five multiple representations (MRs) used in this study namely: (a) drawing/sketch, (b) free-body diagram/FBD, (c) description, (d) mathematical equation, and (e) concept map (Know - Want to know - Learn). These MRs were embedded in the teacher’s lesson plan as a strategy for teaching and learning selected topics in Mechanics. All these MRs were used by the teacher to discuss each lesson, and by the students to understand and do the tasks given to them. The conceptual understanding of the students was measured by obtaining the mean scores from the formative test scores in the form of a 10-item quiz for the following topics - Kinematics, Laws of Motion, and Universal Law of Gravitation. The students’ metacognitive awareness was measured using the 52-item metacognitive awareness inventory (MAI) questionnaire, given before and after the implementation of the teaching-learning intervention. Students’ perceptions on the use of MRs were also gathered in the form of short responses to a 5-item questionnaire. Their responses to these questions were used to elaborate and explain the results in the subcategories of the MAI. Mean scores in the formative tests revealed that students obtained passing grades in all three quizzes. Results also showed that there was an increasing trend in the students’ mean scores from Quiz 1 to Quiz 3. Paired t-test also showed that the increase in the students’ scores moving from Quiz 1, Quiz 2, to Quiz 3 were significant at p < 0.05. The results of the Metacognitive Awareness Inventory (MAI) questionnaire revealed that a significant difference was observed, when comparing the students’ profile scores before and after the implementation of the teaching-learning intervention. The use of multiple representations (MRs) made the students more aware of how they think about learn the physics concepts.

Shafira Aulia Putri, Puardmi Damayanti, Atin Nuryadin, Nurul Fitriyah Sulaeman — Fri, 26 Apr 2024 00:00:00 +0000

Global trends show that men dominate physics-related jobs. However, there is a unique phenomenon, especially in Indonesia in the physics teacher education program where there are more female students than male students. This study aims to determine the TPACK of female pre-service physics teachers consisting of 15 pre-service teachers taking microteaching courses and making their online learning videos. The videos were used as a data collection tool. A microteaching observation sheet was used to analyze data obtained from observations with two raters. The observation sheet consisted of 6 aspects which were content knowledge (CK), pedagogical knowledge (PK), technological knowledge (TK), pedagogical content knowledge (PCK), technological content knowledge (TCK), and technological pedagogical knowledge (TPK) with four indicators for each aspect and the maximum score per aspect is four. The overall TPACK score was obtained by calculating the average of all aspects. Although the overall result of female pre-service physics teachers is 2.1 which is sufficient, technological-related aspects need more concern. The results showed that female pre-service physics teachers lack technological pedagogical knowledge (TPK). On the contrary, they have high pedagogical knowledge (PK). Teacher education programs should provide opportunities for female pre-service teachers to develop their TPACK. Online microteaching can be the key to helping female pre-service physics teachers to integrate technology into their learning.

Critical thinking skill is one of the abilities that must be possessed by students in the 21st century. Students are currently not trained to always think critically, which could be caused by the learning styles of the students themselves. The learning style here is a combination of a person’s state of being able to absorb, be able to organize, and be able to process information. This study aims to analyze the implementation and relationship of learning styles with critical thinking skills after the hybrid learning model is applied to the work and energy materials. The method used correlation analysis with product-moment correlation. The sample of this research was the students of class X MIPA, totaling 16 students who were selected by using the saturated sampling technique. The instruments used were a learning style questionnaire (an authentic assessment based on teaching and learning trajectory) with student activity sheet (AABTLT with SAS), and critical thinking skills test questions. The results showed that the average percentage of learning implementation using the hybrid learning model was 91% with a very effective category. The results of the hypothesis test using the product-moment correlation test, then count (0.110) < table (0.497) or count less than stable, so Ha is rejected and H0 is accepted. The results of this study can conclude that there is no significant relationship between learning styles and critical thinking skills of students of class X MIPA on the matter of work and energy.

This study intends to analyze geometry tasks related to Higher Order Thinking Skills (HOTS) through geometrical thinking level by Van Hiele which consists of visualization, analysis, abstraction, deduction, and rigor. This study only focuses on visualization, analysis, and abstraction levels. The stages in this study are divided into three steps. Chronologically, the first stage begins with the process of compiling PISA tasks related to geometry and HOTS, especially for examining the students’ spatial abilities. From all the tasks obtained, three tasks match the criteria that were most relevant to Van Hiele’s geometrical thinking level. The second stage was continued by testing the instrument test to 23 students from one of the schools in Tangerang Regency as respondents. In the last stage, analyze the students’ answers based on the steps of their work and compare them with the theory of geometrical thinking from Van Hiele. The results of this study indicate that there are differences between the steps of the students’ answers and theoretical answer steps that are expected in this study. The conclusion that can be drawn is that the students’ learning experiences in understanding geometrical concepts are not theoretically compatible with the principles of spatial ability, especially in completing geometry tasks related to HOTS.

Fitri Nuraeni, Hafiziani Eka Putri, Nuur Wachid Abdul Majid, Sofyan Iskandar — Fri, 26 Apr 2024 00:00:00 +0000

Insufficient comprehension of integrated STEM learning has become one of the main difficulties for teachers in implementing STEM lessons at school due to lack of integrative STEM curriculum in teachers’ education programs. Therefore, the Elementary Teacher Education Program Universitas Pendidikan Indonesia in Purwakarta offers STEM Education for Elementary course as an optional course to support 21st-century education at the elementary school level. However, due to the continued Covid-19 pandemic, during the second semester of the academic year 2020/2021, all courses in our program were entirely carried out online. Through the descriptive analysis method, this paper details how the 16-weeks course was enacted online with a varied delivery form. Forty-two pre-service teachers enrolled in the course. Data on the course implementation were gathered in the form of video recordings of the lesson, while students’ perception of the course delivery was captured through a course evaluation questionnaire. Results imply that the course includes a theoretical and practical session with teaching simulations and engineering challenges to model STEM teaching and learning to develop pre-service teacher’s STEM pedagogical and content knowledge. In addition, course evaluation suggests that after enrolling in the course, the pre-service teacher has positive perceptions of the course delivery.

The Effect of STEM Approach in Problem-based Learning for Increasing Students' Problem-solving Ability in the Topic of Environmental Pollution

‎ Parno, Novida Pratiwi, Faizza Amaliah Putri, Marlina Ali — Fri, 26 Apr 2024 00:00:00 +0000

Environmental pollution is a manifestation of the interaction between living things and their environment. However, students still have low problem-solving ability (PSA) in this topic. Meanwhile, STEM approach implementation in problem-based learning (PBL-STEM) to grow students’ PSA is still rarely used. This study aims to improve students’ PSA by implementing STEM approach in PBL on the environmental pollution topic. This quasi-experimental research uses a pre- and post-test design. This study was done on a group of 64 7th grade students, who were equally divided into experimental class (PBL-STEM) and comparison class (PBL) In completing the worksheet during learning, the experimental class students were required to be more active in terms of thinking, than the comparison class students. This study uses the environmental pollution problem-solving ability test instrument, which consists of 13 essay items with a Cronbach alpha reliability of 0.785. Pre- and post-test data were analyzed using independent t-test, N-gain, and d-effect size. The results showed that students who studied through PBL with the STEM approach had significantly better PSA than students who studied through PBL. Also, students in the experimental class had a larger N-gain increase compared to the comparison class, both in total topics and subtopics of environmental pollution. Even in the subtopic of noise pollution, the PSA of the subjects in experimental class improved one level higher than the subjects in comparison class. Both classes had the same increase in succession from large to small, namely, water, soil, air, and noise pollution. The practical implementation of the research resulted in a d-effect of 0.782 medium category. Therefore, the STEM approach in PBL affects increasing students’ PSA on the topic of environmental pollution. In future research, it is recommended to add “Religious” and “Art” aspects of STEM, and be equipped with formative assessment in the whole learning process.

Analysis of Students' Combinatorial Thinking Model in Solving Combinatorics Problems

Rita Desfitri — Fri, 26 Apr 2024 00:00:00 +0000

The purpose of this study was to analyze students’ combinatorial thinking in solving combinatorics problems. This study was organized into two related areas. The first focused on whether students applied combinatorial thinking in Lockwoods’ model, and the second emphasized on students’ ability in solving the given combinatorics problems. This research method used was a qualitative descriptive method. Participants of this study were students majoring mathematics education at Bung Hatta University who took combinatorics courses. Five combinatorics problems were given to the students and then analyzed. The result showed that based on Lockwoods’ model, the aspect of combinatorial thinking that was more widely applied in solving combinatorics problems was the counting process. However, most students who were able to solve problems quite well, and tended to solve problems with steps from formulating, followed by the process of counting to reach a set outcome. Whereas students who did the counting process stage without formulating problems into mathematics expressions, generally checked a set of outcomes by trial and errors. It can also be noted that in general, f/or any problem given, the percentage of students who faced difficulties when formulating problems into mathematical expressions or on the counting process was more that 50%, and the number of students who reached the correct set of outcomes was relatively low.

Hypothetical Learning Trajectory Through the Problem-Based Learning in Junior High School Students

Fri, 26 Apr 2024 00:00:00 +0000

The purpose of this study was to determine the hypothetical learning trajectory through a problem-based learning model to class VIII junior high school students. Learning mathematics requires a meaningful process and that process cannot be obtained in a relatively short time because it requires good preparation in conveying mathematical concepts to students. The preparation is designed according to the characteristics of students so that the delivery of the material goes well as expected. The preparation referred to in this case is to design a good hypothetical learning trajectory (HLT) according to the needs and subject matter. Hypothetical learning trajectory (HLT) is a temporary hypothesis about students’ activities in the learning process on certain materials. This study uses a design research method with stages referring to Plomp (2013) which consists of three phases including (1) preliminary research; (2) development or prototyping phase; and (3) assessment phase. However, in this research, it is only in the first phase, namely preliminary research. In designing the HLT, it is based on a problem-based learning model which has five stages in each process. The instrument used in this study was a teacher and student interview sheet. The results obtained are the HLT design on linear equation material that is adjusted to the stages in the problem-based learning model. The results obtained from this study can be used as an initial reference for mathematics teachers in designing learning material for linear equations that are in accordance with the real context of students.

This study examines the development of “science process skill” research through a bibliometric approach to computational mapping analysis using VOSviewer. The article data was obtained from the Google Scholar database using the publish or perish reference manager application. The title and abstract of the article are used to guide the search process by referring to the keyword “science process skill”. Nine hundred sixty-seven articles were found that were considered relevant. The study period used as the study material is the Google Scholar-indexed article for the last six years (2018 to 2023). The results showed that science process skill research can be separated into 3 terms: science process skill, process skill, and science process. The first term is “science process skill” that is included in cluster 1, which has 71 links, a total strength of 4342 links, and 888 occurrences. The second term is “process science”. This term is included in cluster 4, which has 61 links, a total link strength of 278, and 47 occurrences. The third term is “process skill”. This term is included in cluster 3, which has 67 links, a total link strength of 570, and 100 occurrences. There was an increase in the number of publications from 2018 to 2021. However, it experienced a decline in 2022 up to July 2023. This indicates a decreasing trend in the number of publications in research on science process skills in the last three years, from 2021 to 2023. The results show that research related to science process skills still has a high enough opportunity to be researched. Several keywords related to “science process skills” have not been or are rarely used in research, some of which are an integration of learning models, prospective teachers/pre-service teachers, mixed methods research, assessment of learning, assessment as learning, and assessment for learning. This review can serve as a starting point for research related to other materials.

The ability to think creatively and critically is considered the main cognitive competency. This study aimed to measure the thinking ability of students (n = 33) who participated in a laboratory activity in analytical chemistry. Case study methods were used to collect qualitative data, which supports quantitative data. The student’s creative and critical thinking abilities are measured by correlating the test result with their observations and responses. The results show that the student’s creative and critical thinking abilities are qualified as sufficient. An average of 46.96% of the students could provide correct answers, with the highest percentage on mixture separation tasks (72.7%). The students also showed creative and critical thinking abilities in creating and defining the result after consideration, resolving problems, providing answers with sound reasoning, observing, creating combinations and objects, and detailed ideas regarding the task indicators. The students could also define terms, analyze questions, and adapt their approaches to resolve tasks. The abilities of some students to identify problems from several points of view are still considered low, and they need to be able to identify issues based on given pictures and assess topics from different perspectives. The laboratory activity should create more indicators to think critically and creatively about every aspect.

The primary objective of this study is to gather empirical data regarding the implementation of organic compound separation and purification techniques at tertiary educational institutions to examine their efficacy as a proactive step to facilitate ongoing educational endeavors. The elements discussed include the practicum topics completed, the organic chemistry instruments and equipment possessed, how the practicum is conducted, and the problems and their resolutions. This study’s respondents included course instructors, chemistry lab assistants, and students previously attending practicum content. This study used a qualitative research methodology to analyze multiple chemistry education study programs across various locations in Indonesia. Data collecting methods include open-closed surveys, observation, and documentation. The findings indicated that the separation and purification practicum topic incorporates concepts related to separation and purification, employing extraction, chromatography, distillation, sublimation, and recrystallization techniques. Some chemistry education programs needed adequate instrumentation for organic chemistry. In addition, the wet laboratory practicum for separating and purifying the studied organic compounds are yet to be completed as per the planned topics. Green chemistry and project-based learning have been largely implemented in the practicum, but the micro-scale concept, which can help reduce practicum waste, are yet to be implemented. Inadequate tools and materials for the practicum, as well as inadequate reference materials, are some of the obstacles that hinder the practicum’s efficiency. Hence, there is a want for pragmatic instruments that can effectively cater to the demands of ongoing education. This practicum set should facilitate using green chemistry and micro-scale, focusing on minimizing pollution that can harm the environment.

Connecting Students to Local Wisdom to Learn Science for Sustainable Development Goals: A Conceptual Framework

Erman Erman, Nur Wakhidah — Fri, 26 Apr 2024 00:00:00 +0000

Today science learning is not only for understanding science but also for explaining phenomena, solving relevant problems, and even developing the economy and its welfare (sustainable development). To achieve this goal, local wisdom-based learning is very strategic as a productive context in learning science, becoming an interception between science and the social dimension. Using a qualitative content analysis approach supported by the literature and the results of our previous studies, we conducted an in-depth study of a framework of local wisdom-based learning. The results show that local wisdom can be considered a socio-scientific issue, as it has an identical conceptual framework in learning. To study science, especially for sustainable development goals (SDGs), students need connections with scientific ideas and social concerns of local wisdom. IDEA Scaffolding principles can help students learn to connect with the locals’ wisdom.

The Essential Elements of Japan Super Science High School Projects: A Case Study of Shizuoka Prefecture

Fri, 26 Apr 2024 00:00:00 +0000

To support the enhancement of science and technology, the Japanese government established the Super Science High School in 2002. However, there is a lack of information about this school for international scholars. We addressed this problem by observing and working with SSH in Shizuoka Prefecture and understanding their intended school models. The context of Shizuoka prefecture is interesting because it is well-known for its high-technology manufacturing company. Our “bottom-up” approach was mainly based on observation, in contrasts with other studies using a literaturebased method to define SSH schools. We identified four elements that represent the common goals and strategies employed by SSH: Independence scientific research, Scientific English, courses related to STEM, and international collaboration. This framework offers a clear picture of what exactly SSH schools are. Findings suggest that SSH identity is rooted in pedagogy, school culture, and rigorous instruction, especially in science and technology, including support from scientists and researchers from the surrounding universities as invited speakers, teacher assistance, and opportunities to conduct research in university-level laboratories.

How is Reflective Practice in Learning? A Science Teachers Perspective

Selvies Lea Babutta, Riandi Riandi, Ida Kaniawati, Sumar Hendayana — Fri, 26 Apr 2024 00:00:00 +0000

Reflective is a thinking process that can be carried out by teachers, leading to improvements in effective classroom management and quality and improving student performance, so that reflective practices are indispensable in teaching and learning practices. This study aims to describe the reflective practice of science teachers in junior high schools. Primary data were collected based on the teacher’s experience in teaching science learning, highlighting three aspects including reflective action, the form of reflective action, and follow-up to reflective activities. This qualitative study was conducted through the distribution of online questionnaires. The results indicate that reflective action in learning by science teachers is always carried out, but the form of reflective action has not yet involved many peers, principals, and supervisors. Most often done by teachers themselves, to accept other people’s thoughts, learn, or share good practices have not fully occurred. The follow-up of reflective activities has not been followed by changes to the design of further learning in the lesson plan, but teachers are more focused on changing the teaching process that they do in class independently.

Adopting Model United Nations (MUN) in Discussion Method in Learning Environmental Pollution: D-MUN Method

Nadia Mubarokah, Melvika Anggraini, Riandi Riandi, Irma R. Suwarma — Fri, 26 Apr 2024 00:00:00 +0000

In the classroom, the discussion method has objectives to train the students with several skills, such as assertiveness when arguing with opposing ideas, the ability to brainstorm, groupthink, and improved communication with their peers. However, implementing the discussion method requires more preparation to run well. Improper organization of class discussion leads to no clear point or lesson learned that is explicitly stated after class discussion. Students’ participation becomes difficult to monitor whether all students contribute during the class discussion. They only talk when being pointed out by the teacher, and they will not speak if they do not have something to say. Science teachers’ experiences in conducting discussion methods were gathered before the study. Using the results from the preliminary survey, a conceptual framework of the discussion method by adapting Model United Nations (MUN), thus the so-called D-MUN METHOD, in learning about environmental pollution was developed. By adapting the structure of the discussion used in MUN to the classroom while learning science topics, the discussion in class becomes more engaging and increases students’ active participation and clarity of key concepts. The issues that become the topic of discussion should be relevant to the science content and include ill-structured problems. Therefore, the D-MUN METHOD will encourage students to present their solutions, which depends on their point of view (assigned as a specific country/region representative), and, in the end, come together to produce the best resolution.
