Abstract

This study aims to develop effective, feasible, and valid encyclopedia media on form and function of plant to train fourth-graders critical thinking skills in the elementary school. This study was research and development based on Borg and Gall theory and Research (R& D) model. Data were collected using observation, questionnaires, and tests and analyzed using media validity and reliability, student activity, implementation of lesson plans, and tests of critical thinking skills. After that, the media was validated by experts. The results of the expert validation showed that the Encyclopedia media was valid for use. Furthermore, the media was tested on fourth-graders of SDN KERTAJAYA V / 211 Surabaya using One Group Pretest-Posttest Design. The limited scale trial results showed (1) the validation of the developed Encyclopedia media were 96% valid categories, (2) the developed media were tested in term of lesson plan implementation were 94% with well-implemented category and student activities were suitable to Discovery Learning model, (3) the effectiveness of the Encyclopedia media in terms of students critical thinking skills tests showed that average N-Gain was 0.75 (high) and positive response of 97% was given by students. Therefore, it can be concluded that the Encyclopedia media on Form and Function of Plant is feasible to train Critical Thinking Skills of Elementary School Students.

Abstract

Metacognitive skills in learning are an important indicator that can be measured. Based on the test of metacognitive skills when pre-study obtained the results that the metacognitive skills of learners are still relatively low. One of the learning strategies that can be used to improve the metacognitive skills of learners is a learning strategy oriented self regulated learning (SRL) by utilizing textbooks in the form of supplement books. Therefore, this study aims to describe the feasibility of self-regulated learning (SRL) oriented acid-base material supplement books to improve metacognitive skills of learners. This type of research is Research and Development (R&D) according to the Borg and Gall model. Validity Data obtained through validator assessment using validation questionnaire. Practicality Data obtained through the results of the questionnaire responses of students supported by the results of the observation sheet activities of students. Practicality Data were obtained through pretest and posttest of learners metacognitive skills supported by the results of metacognitive inventory questionnaire. The validation results showed that the content and construct validity criteria were declared valid with a median of 5. Practicality is stated to be practical in terms of the results of the questionnaire responses of students who showed a very strong category with the percentage of content criteria, language, presentation and graphics of 94,25%, 90,67%, 95% and 98,3% respectively with the results of the average percentage of observation sheet activity of students at 96,67%. Effectiveness is stated to be effective in terms of Paired Sample t-test results with sig. values 0.05 and N-gain pretest and posttest scores of metacognitive skills in the high category with the results of the metacognitive inventory questionnaire showed a very strong category with an average percentage of 90,8%. The results showed that the book supplement oriented material acid base self regulated learning (SRL) feasible to use as a solution to improve the metacognitive skills of learners.

Abstract

This study aims to determine the implementation of learning and students' critical thinking skills after the implementation of cooperative learning model type Group Investigation on matter of reaction rate. This research type is Pre Experiment (pre experimental design) and research design used is One-Group Pretest-Postest Design. Target of this research is student of class XI MIPA 6 SMA Negeri 1 Manyar. The instrumentsused are an observation sheet of cooperative learningmodeltype Group Investigation and sheet of pretest and postest of critical thinking skill. The results showed that (1) The implementation of cooperative learning model type Group Investigationis in good and very good category with percentage in every phase is:in phase 1 was 87.5%; phase 2 was 95.84%; phase 3 which contains stage 1 and stage 2 of the Group Investigation was 87.5%; Phase 4 which contains stage 3, stage4, and stage5 of the Group Investigation was 95.84%; phase 5 which contains stage 6 of Group Investigation was100%; (2) Students’ critical thinking skill in terms of N-gain shows that 85% of students get high N-gain category and 15% of students get N-gain in moderate category.

Abstract

This study is conducted in response to the low levels of students’ critical thinking skills, particularly in interpretation, analysis, inference, and explanation, in the context of acid-base chemistry, as well as the scarcity of digital resources that promote active learning. The objective is to develop a problem-solving-based E-Student Liveworksheet to improve critical thinking skills related to acid-base material. Research and Development (R&D) was employed, following the 4D model (Define, Design, Develop, and Disseminate). The feasibility of the developed worksheet was evaluated using Nieveen’s criteria: validity, practicality, and effectiveness. Data were gathered through expert validation forms, student questionnaires, classroom observations, and critical thinking tests. The study involved eleventh-grade students at Gedangan Senior High School. Validation results showed a mode score of 4, indicating high content validity. The practicality score from student responses reached 95%, categorized as "very good." Effectiveness was demonstrated by n-gain scores ranging from 0.50 to 1.00, reflecting moderate to high improvement across all critical thinking indicators. These findings confirm that the liveworksheet is a valid, practical, and effective tool for enhancing students’ critical thinking in acid-base learning. In conclusion, the developed digital resource supports the goals of the Independent Curriculum by fostering interactive, contextual, and problem-based learning. This innovation offers valuable potential for broader application in science education and serves as a reference for integrating technology to promote higher-order thinking. Future research is recommended to explore its long-term impact and adaptability across various scientific topics and learning environments.
