Abstract

Research on the Effectiveness of Concept Change Oriented Learning with Dual Situated Learning Model (DSLM) Assisted by Multi Representations (MRs) to Improve Acid-Base Concept Understanding of High School Students is a quantitative study which employs a quasi-experimental design with a non-equivalent control group design pretest-posttest. The research subjects were 70 students of class XI pattern 5 SMAN 4 Malang for the academic year 2020/2021 which comprised two classes taken by cluster random sampling, one class as the control class (34 students) and one class (36 students) as the experimental class. The research data was collected using the acid-base concept understanding test instrument (TPKAB) which comprised 25 items (17 items for two-tier questions and 8 items for multiple choice). The research hypothesis was examined through the ANCOVA test assisted by the SPSS 21.0 for windows program with a significance level of = 0.05. The results demonstrated the increase in the average value of the experimental class was higher than the increase in the average score of the control class after learning acid-base material. Meanwhile, the results of the delay-test demonstrated the PK-DSLM-MRs were effective in maintaining the retention of students' conceptual understanding on acid-base material. PK-DSLM-MRs gave the strongest influence on the group concept of acid-base strength. The number of misconceptions and students who experience misconceptions in the control class is more than the number of misconceptions and students who experience misconceptions in the experimental class.

Abstract

This study aimed to explore whether Explicit Scientific Inquiry Instruction (ESII) Hybrid Mode in the context of Socioscientific Issues could improve the students' critical thinking skills. The research design was a one group pretest-posttest design. The research sample was 31 science eleventh graders at SMA Mojosari for the academic year 2021/2022. The data was collected using a critical thinking skills test on Chemical Kinetics which consists of 27 valid questions with a Cronbach Alpha reliability of 0.756. A paired-samples t-test showed that the Explicit Scientific Inquiry Instruction (ESII) Hybrid Mode in the Socioscientific Issues context improved students’ critical thinking skills (p = 0.00 < 0.05). The improvement was strong as its N-gain score was 0.58 (upper–medium category) and d-effect size was 1.40 (much larger than typical category). This shows that statistically ESII hybrid mode in the context of SSI can improve students' critical thinking skills. Therefore, this strategy can improve students' critical thinking skills in the instruction that allows students to interpret, analyze, explain, evaluate, and draw conclusions

Abstract

Kemunculan bakteri resisten antibiotik menjadi masalah serius di seluruh dunia. Upaya penanggulangan bakteri resisten antibiotik terus dilakukan, salah satunya dengan penggunaan material berukuran nano. Zink oksida (ZnO) merupakan salah satu partikel yang telah terbukti dapat menghambat pertumbuhan bakteri gram negatif dan gram positif. Dalam mencegah terjadinya aglomerasi pada sintesis ZnO berukuran nanometer dapat ditambahkan capping agent alami berupa senyawa metabolit sekunder pada ekstrak kulit pisang raja nangka. Adapun langkah yang dilakukan adalah: 1) ekstraksi metabolit sekunder kulit pisang raja nangka, 2) uji fitokimia, 3) penentuan kadar total flavonoid dan polifenol, 4) sintesis ZnO dengan capping agent alami ekstrak kulit pisang raja nangka, 5) karakterisasi ZnO, dan 6) uji aktivitas antibakteri ZnO. Hasil analisis kualitatif melalui uji fitokimia serta analisis kuantitatif melalui penentuan kadar total polifenol dan flavonoid menunjukkan bahwa ekstrak kulit pisang raja nangka etanol (96%)-air 2:1 (v/v) memiliki kadar metabolit sekunder yang lebih tinggi dibandingkan ekstrak kulit pisang raja nangka etanol (96%)-air 1:1 (v/v). Partikel ZnO berhasil disintesis menggunakan capping agent alami ekstrak kulit pisang raja nangka. Kadar metabolit sekunder yang berbeda pada masing-masing ekstrak mempengaruhi ukuran, morfologi, dan aktivitas antibakteri ZnO hasil sintesis.

Abstract

The abstract nature of chemical equilibrium learning material tend to result in misconception. The issues of misconception are identified using multi-tier diagnostic tests. This study aims to examine previous studies investigating the multi-tier diagnostic test in investigating the misconception of chemical equilibrium. We adopted a systematic literature review using the PRISMA method in analyzing 30 scientific articles discussing chemical equilibrium misconception and their analysis methods. The results of our content analysis suggest a number of multi-tier diagnostic test types that can be used to analyze the chemical equilibrium misconception, namely the two-tier, three-tier, and four-tier diagnostic tests.

Abstract

Abstrak – Nowadays, the demands of curriculum are increasing in achieving better standards of learning process. The low ability of chemistry and science teachers in developing inquiry-based and project-based learning designs is a problem that must be solved. The ability of teachers in making learning designs is one of the pedagogic competencies and professional competencies that teachers must master in their professional development. So there is a need for community service or training to teachers to facilitate this. The method of implementing this community service activity includes the presentation of material on inquiry-based and project-based chemistry learning design, discussion and question and answer, and assistance to teachers in developing the learning design, until teachers are able to make inquiry-based and project-based chemistry learning tools (including lesson plans, teaching materials, and assessment instruments). The result of the training activities was an increase in the knowledge and skills of chemistry and science teachers regarding making inquiry-based and project-based learning designs. Enthusiasm and curiosity in developing knowledge about learning design make this training activity useful for participants.Keywords: Learning Design; Inquiry; Project; Teacher; Training

Abstract

This study aims to determine the effectiveness of IDEAL-type metacognitive combined with STAD cooperative learning to improve students' self-efficacy and problem-solving abilities in thermochemistry. The research design used was a Quasi-Experimental Pretest-Postest Control Group Design and a 2 x 2 factorial design. The experimental class was taught with the IDEAL type metacognitive learning strategy combined with STAD cooperative learning, while the control class was taught with the STAD cooperative learning model. The data analysis technique used is descriptive analysis and different tests. The results showed that the IDEAL type metacognitive learning strategy combined with STAD cooperative learning was more effective in improving students' problem-solving abilities than the STAD cooperative learning model. However, it is not effective in increasing students' self-efficacy. Suppose students are taught with the IDEAL type metacognitive learning strategy combined with STAD cooperative learning and accompanied by high learning motivation. In that case, the students' self-efficacy and problem-solving abilities also increase even though the interaction between the two is weak. REFERENCESAriff, S.S., Kumar, S.V., Azizi, M.N., & Hilmi, F. 2022.

Abstract

This research aims to enhance prospective chemistry teachers’ scientific argumentation skills through integrated chemical literacy strategy (ICLS) learning and to examine the patterns of relationship between students’ scientific argumentation skills in terms of content and socio-scientific issues (SSI). The study used mixed methods: the embedded design with embedded experimental model. The research sample was 88 students, the control and the experimental groups each consisted of 44 students. The research instrument used scientific argumentation skills test: an open and closed essay test, and interviews with 10 students as selected respondents. Data analysis used descriptive analysis, N-gain, Mann-Whitney test, effect size test, and qualitative analysis. The results showed that ICLS significantly had a great influence on enhancing students’ scientific argumentation skills. The interview results show that: the level of scientific argumentation skills related to SSI is not consistently related to content-related scientific argumentation skill; students who have scientific argumentation skills related to SSI levels 4, 3, and 2 can provide the correct claim, data, warrant, backing, and rebuttal to scientific arguments related to content if guided by guiding questions; student that had higher level of scientific argumentation skills need fewer guiding questions.

Abstract

The lack of instruments designed to assess chemical literacy among prospective chemistry teachers highlights the need for robust tools to support science education. This study develops and validates an instrument to measure chemical literacy, addressing this gap and contributing to improved pedagogical practices. In this study, a chemical literacy instrument for general chemistry was developed, drawing on existing frameworks of chemical literacy. This research employs a development-based approach (RD), encompassing literature review, instrument development, and quality testing. The quality of the instrument was evaluated based on its reliability and validity. The validity was evaluated by expert panel review, difficulty index, discrimination index, and pearson correlation value. In this study, a multiple-choice chemical literacy test instrument was successfully developed using the PISA 2025 scientific literacy framework, resulting in 23 valid items. The PISA framework was chosen for its perceived dynamism compared to other frameworks. The reliability of the developed instrument reached 0.818, indicating that the questions are highly reliable. Future improvements to the instrument are necessary, with a focus on ensuring that all items fully meet the established validity criteria

Abstract

Problem solving is one of the abilities that students must have in the 21st century. This is because students' ability to solve problems is expected to increase their higher order thinking skills (HOTS) competency. The ability to measure problem solving can be assessed through test instruments in the form of questions containing problems. This research aims to analyze problem solving abilities in colloidal materials through the development of the IDEAL Problem Solving assessment instrument. This instrument includes five indicators, namely Identify the Problem, Define the Outcome, Explore Possible Strategies, Anticipate Outcome & Act, and Look back and Learn. The research was conducted for 3 months at SMAN 1 Sungai Tabuk class XI semester II (even). The method used is development research or R&D (Research and Development) research. The development of this instrument adapts the ADDIE development model by following five steps, including (1) Analyze (analysis), (2) Design (planning), (3) Develop (development), (4) Implementation (implementation), (5) Evaluate (evaluation). Data analysis was carried out quantitatively with statistical tests. The empirical validity results show that the instrument is valid and reliable to use and meets the criteria for a good level of difficulty and discrimination.
