Abstract

This study focuses on creating Student Worksheets (LKPD) that incorporate Assessment for Learning principles to improve students' scientific process skills in chemical equilibrium. The research employs the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model of Research and Development (R&D). The study evaluates the LKPD's effectiveness, practicality, and validity. A one-sample t-test comparing pretest and posttest scores measures effectiveness. Practicality is determined through quantitative descriptive analysis of student feedback questionnaires and activity observation sheets. Validity assessment involves both qualitative and quantitative descriptive analysis using Likert scale validation forms. Results show that the developed LKPD achieved the highest possible validity score (mode of 5) across all aspects. It demonstrated 90.7% practicality and a statistically significant t-test result (p-value of 0.000). These outcomes suggest that the LKPD effectively enhances students' scientific process skills in chemical equilibrium studies. The Assessment for Learning approach and integrated feedback in the LKPD promote active student engagement and foster improved scientific process skills in this subject area.

Abstract

An initial survey showed that some chemistry teachers at the MGMP of Mojokerto Regency and City had never attended argumentation skills training. Argumentation skills are important to practice as an effort to improve critical thinking skills, improve understanding and problem solving. This activity aims to improve the understanding and skills of chemistry teachers in Mojokerto in developing argumentation-based evaluation questions. This activity was carried out in two sessions through six stages of activities starting from preparation, training, monitoring, implementation, evaluation, and appreciation stages. The results showed that the development of teachers' understanding related to argumentation skills was analyzed using the N-Gain score and the majority were in the moderate group. The results of the question development also showed an increase in the level of argumentation skills. The response questionnaire showed that all teachers supported this PKM activity and the activity had been 100% implemented. This activity is expected to be one of the triggers for teachers to make their students more critical, creative and able to solve problems well through argumentation skills training.

Abstract

Educational developments in the 21st century require students to be prepared to face global competition. This preparedness can be supported by several basic skills that are equipped to each student as the future generation of the nation, for example, science literacy. Specifically, the study aims to produce and test the validity of a phenomenon-based advance organizer learning tool consisting of a teaching module, student worksheet, textbook, and science literacy assessment instrument. The method used is RnD, with the research design chosen being Thiagarajan's 4D model, which consists of define, design, develop, and disseminate. Data were obtained from three expert validators through validation sheets and analyzed using Aiken’s V formula to determine the validity level of each component of the developed learning tools. The expected outcomes include teaching modules, student worksheets, textbooks, and science literacy questions to be applied in chemistry education. Research data was obtained from three validators using a validation sheet. The validators consisted of two lecturers from the Faculty of Mathematics and Natural Sciences at Unesa and one chemistry teacher from Puri 1 Senior High School in Mojokerto Regency. The data was analyzed based on the validity criteria of each element of the learning tools using Aiken's validation. Previously, the learning tools were reviewed by two chemistry lecturers from the Faculty of Mathematics and Natural Sciences at Unesa with the assistance of a review sheet to obtain suggestions and input. The validity data showed that the learning tools were valid, with validity data meeting the validity criteria, where the teaching module scored 0.86 on the Aiken scale, the student worksheet scored 0.86 on the Aiken scale, the textbook scored 0.89, and the science literacy questions scored 0.99. These findings indicate that the developed learning tools meet high validity criteria and are suitable for use in chemistry learning. The integration of the phenomenon-based approach with the advance organizer model provides a structured framework that helps students connect abstract chemistry concepts with real-world phenomena, thereby improving science literacy and engagement. In conclusion, the phenomenon-based advance organizer chemistry learning tool developed in this study is valid and feasible to be implemented in high school classrooms to train students’ science literacy skills, and further research is recommended to test its effectiveness in improving learning outcomes.

Abstract

Purpose – This study aims to describe AfL-based student worksheets as a means of improving students' critical thinking skills in Basic Chemistry learning.Methodology – This pre-experimental study employs a one-group pre-test post-test design. The data obtained were analyzed using a mean difference test and an N-gain score. Students' critical thinking skills are considered to have improved if there is a significant difference between the pre-test and post-test scores, and at least 55% of students in a class achieve a medium and/or high criterion of N-gain score.Findings – The mean difference test revealed a significant difference in the pre-test and post-test scores of students' critical thinking skills. The N-gain score measurement showed that the percentage of N-gain score in the medium and high criteria was higher than 55%. This implies that implementing AfL-based student worksheets can enhance students' critical thinking skills in Basic Chemistry Learning.Contribution – The research results reinforced previous findings that AfL implementation can improve students' critical thinking skills, especially in chemistry learning. In addition, feedback on the implementation of AfL can help students identify their strengths and weaknesses in learning, which they can use to improve their learning.
