Abstract

This study aims to; 1) Describe the steps of developing STEAM-Project-based E-LKPD to improve students' chemical literacy on colloidal system material, and 2) Describe the validity, practicality, and effectiveness of STEAM-Project-based E-LKPD in improving students' chemical literacy on colloidal system material. This type of research is Research and Development (R&D). Learning activities follow the syntax of the STEAM-Project learning model which begins with determining fundamental questions, designing projects, monitoring the activeness and progress of students' projects, then assessing the results. The research subjects were 33 students of class XI MIPA 7 SMA Negeri 9 Gowa in the 2023/2024 academic year. This research uses Thiagarajan's 4D development model which consists of 4 stages, namely the Define stage, Design stage, develop stage, and disseminate stage. However, this research is limited only to the Develop stage for certain considerations. The instruments used in this study are validity instruments in the form of instrument validation sheets, practicality instruments in the form of teacher response questionnaires, student questionnaires, and implementation questionnaires, and effectiveness instruments in the form of evaluation tests. The results of the study obtained; 1) the product validation index of 0.88 with very valid criteria, 2) the average percentage of product practicality from the responses of teachers and students in the small-scale trial stage.

Abstract

This Study is a development research that aims to produce interactive media based on appypie reality in a valid, practical, annd effective pronlem based learning model. The development model used is the ADDIE development model which consists of five stages, namely the analysis stage, the design stage, the development stage, the implementation stage, and the evaluation stage. The interactive media based on appypie that was developed was validated by two experts. Then, it was tested to 29 students in grade XI MIA 3 SMAN 3 Pinrang. The analysis used is data analysis of validity, practicality and effectiveness. The interactive media based on appypie is stated to valid based on the result of validating interactive media based on appypie with an average value of the media expert of 3.76, which are in very valid category. The interactive media based on appypie is stated to be practical based on (1) the implementation of interactive media with an average total percentage of 95,60%, which is in very high category; (2) the teacher's response with an average score of  95,75%, which is in very practical category; and (3) the students’ responses with an average score of 88,25%, which is in very practical category. The interactive media is stated to be effective based on the results of the analysis of the learning outcomes test and analysis of learning interest questionnaires with a class completeness percentage of 84% and an average value of the percentage of learning interest assessment of 81%, which is in high category. Therefore, the results of the study indicate that interactive media based on appypie in the proble, based learning learning model has valid, practical, and effective qualities.

Abstract

In this era of independent learning, students must strengthen their numeracy skills. The purpose of this study is to determine the process of developing web-based learning media google sites using a scientific approach to train student numeracy on basic chemical law material, determine the feasibility of learning media based on the assessment of validators, and determine the responses of teachers and students to the learning media. The research and development (R&D) model used is the ADDIE model (analyze, design, development, implementation, and evaluation). The research instruments used were interview guidelines, validation sheets and questionnaire sheets. Validation was carried out by a team of experts who were chemistry lecturers and chemistry teachers. Limited trial subjects were 29 students of class X MA Al-Ma'arif Plus Tulungagung Skills. The data analysis technique used is descriptive quantitative and descriptive qualitative. The results of this study are to produce a product in the form of google sites website-based learning media using a scientific approach to train student numeracy on basic chemical law material, product feasibility gets an average percentage from a team of experts of 91% with “very valid” criteria, teacher responses obtained an average percentage of 95% with “very valid” criteria and student responses obtained an average percentage of 79% with “feasible” criteria. Thus it can be concluded that the learning media based on the google sites website using a scientific approach is feasible to use as a learning media.

Abstract

This research is a development research (Research and Development) with the objectives: (1) to assess the quality of the instrument in terms of content validity and empirical validity, (2) to determine the reliability of the developed instrument, and (3) to assess the practicality of the developed instrument. The product developed is a contextual science literacy assessment instrument on the topic of colloids. The developed contextual science literacy instrument is in the form of multiple-choice questions. The research was conducted using the 4D development model, which includes the stages of define, design, develop, and disseminate. The results of rational validation by two expert validators yielded 15 valid test items with an Aiken's index ≥ 0.75. The instrument was tested on 34 students from class XII MIPA 3 of SMAN 1 Gowa. The results of empirical validation using the point biserial formula at α=0.339 yielded 14 valid test items. The results of the reliability test using KR-20 showed that the instrument was categorized as reliable with a value of 0.831. The analysis of the item discrimination power showed that there were 2 very good items, 6 good items, 4 fair items, and 3 poor items. The distribution of the item difficulty level was 47% difficult items, 40% medium items, and 2% easy items. The practicality of the contextual science literacy assessment instrument on the topic of colloids was categorized as practical based on the positive results of the student questionnaire (85%) and the teacher questionnaire (95%).

Abstract

This study is an experimental research that aims to examine the influence of Predict, Observe, and Explain (POE) learning strategies in the Discovery learning model on the students’ learning motivation and learning outcomes. The research design used was the Posttest-Only Control Design. The population of the study was all students of grade XI MIPA at MAN 1 Barru. The samples were students in grade XI MIPA 1 as the experimental class and grade XI MIPA 2 as the control class. The data analysis techniques used were descriptive and inferential statistical analysis. The results of the study reveal that learning using the Predict, Observe, and Explain (POE) strategy in the Discovery learning model obtain a value of 78% learning motivation, 78% cognitive learning outcomes, 84% affective learning outcomes, and 82% higher skills learning outcomes compared to learning in the control class, so it has significant effect based on hypothesis testing of learning motivation data and learning outcomes with a Sig value. (1-tailed) < 0.05. In addition, learning motivation has a correlation with learning outcomes with Pearson correlation values of 0.824, 0.853, and 0.75. These values indicate that learning motivation has a correlation with learning outcomes at a very high and faily high level of closeness. Therefore, the conclusion of the study is the use of Predict, Observe, and Explain (POE) strategy in the Discovery learning model affects the students’ learning motivation and learning outcomes.
