Abstract

This study aims to examine: (1) the process of developing Prezi-based animated video media in the Discovery Learning Model and (2) the validity, practicality, and effectiveness of Prezi-based animated video media in the Discovery Learning Model. This type of research is Research and Development (R&D), which research procedures following the development of ADDIE. The results of the study show that the validity of Prezi-based animated video media in the Discovery Learning Modelon Oxidation Reduction Reaction material is declared valid and feasible to be used. The finding is based on the validation results by expert validators with a validation value of 3.40 or in valid category. Prezi-based animated video media concluded to be practical and effective because the practicality test of Prezi-based animated video media is related to (1) the implementation in the Discovery Learning Modelis at an average value of M = 1.98 in the category (1.5 ≤ M ≤ 2.0) which means that the aspects and criteria observed are in fully implemented category, (2) the teacher’s response with a percentage of 87.50% with a very practical category and students’ responses with a percentage of 90.20% with a very practical category. Prezi-based animated video media also meets the effective criteria with the results of (1) an increase in students' learning interest from 55.11% to 74.14%, (2) the completeness or achievement of KKM who obtained a score above 75 is 20 people (86.95%) which overallis declared to meet the minimum subject completeness criteria.

Abstract

This research aims to analyze the chemical literacy abilities of students in the Department of Chemistry, Education Class B, UNM Class of 2022, by providing contextual-based exam questions and student response questionnaires using quantitative descriptive analysis methods. The results of the study showed that 84% of the student sample had chemical literacy skills in the medium category, with a score of 42.07 when given contextual-based exam questions. The results of scientific competence as measured in scientific literacy can be improved by routinely providing students with reading material about chemical literacy that is related to scientific phenomena and is appropriate to the context of everyday life. Knowledge of the chemistry learning context and interpreting accurate data emphasizes the use of scientific principles to solve problems according to their application in everyday life, based on student competence in using scientific evidence. There is great enthusiasm for implementing contextual learning, as seen in the questionnaire results of responses given by students through contextual-based questions, which can help students pay attention to what they are learning.

Abstract

This research is a development research, which aims to develop and produce a practical module of reaction rate oriented to discovery learning to train students' science process skills. The development model used in research refers to the ADDIE development model (analysis, design, develop, implementation, and evaluation). The data sources used to measure validity were two validators who assessed the media and practical module material. The practicality data sources were two observers who assessed the learning implementation, 21 students, and two chemistry teachers. Measuring the effectiveness of the practical module employed a science process skills test for 21 students. The field trial of this practical module was conducted at MA DDI Lil Banat Parepare. The results of the research reveal that the practical module is valid, practical, and effective. The module validity, both in terms of the media and material received a very valid category. The results of learning implementation is 97.66% which is in very good category. The teachers’ and students responses using the practical module are in very high category as well, so the practical module is stated as practical. The field trials on 21 students in grade XI MIPA obtained an overall average result of students' science process skills of 83.34 after using the practical module. The practical module developed is stated as effective if the overall average score of the students is 80. Thus, the practical module developed is effective in chemistry practical activities, especially reaction rate material.

Abstract

This study aims to analyze the implementation of Chemistry practicum of grade XI at SMAN in Gowa Regency. The method used is descriptive method with a quantitative approach. The study was conducted at all public high schools in Gowa Regency. The objects were the school’s principals, Chemistry teachers, and all grade XI MIPA students. Determination of the sample employed porposive sampling technique which was based on certain characteristics (schools accredited A, B, and C). Data collection techniques employed observation sheets, questionnaires, interviews, and documentation. The results of the study reveal that the average percentage of the availability of tools and materials to support the practicum implementation is 69%, which is in Appropriate category, while the implementation of Chemistry practicum seen from the average percentage of teachers’ response questionnaires is 84% which is in Very Good category, and the average percentage of the students’ response questionnaires is 80% which is in Good category. The result of the interviews can be concluded that the biggest obstacle to practicum implementation is the lack of availability of practicum tools and materials. The analysis results of the syllabus and lesson plans show that there are ten main subject materials for learning Chemistry. Nine of those main subject materials require practicum activities.

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.
