Abstract

This research is a development research that aims to develop and produce an acid- base e-module based on problem-based learning through google classroom at a vocational high school (SMK) which has valid, practical, and effective criteria. The development model used in the study refers to the 4D development model, which consists of the definition stage, the design stage, the development stage, and the dissemination stage. The acid-base e-module based on problem-based learning developed was validated by two experts. After being validated, the acid-base e-module based on problem-based learning was piloted on students at grade  X TKJ 1 at SMKN 5 Jeneponto of academic year 2020/2021 with 27 students. The results show that the acid-base e-module based on problem-based learning developed had conducted a validation process, measuring the level of practicality and effectiveness. The e-module is stated as valid based on the results of the e- module validation with an average value of 3.27 (valid). The e-module is stated as practical based on: (1) the implementation of the acid-base e-module based on problem-based learning at an average value of 1.9 (fully implemented), (2) the teacher's response with an average score of 97.12 (very practical), and (3) the students’ responses with an average score of 81.34 (very practical). E-module is stated as effective based on the results of the N-gain test of 0.76 (high) and classical completeness of 85.19%. Therefore, the results of the study indicate that the acid-base e-module based on problem-based learning has valid, practical, and effective qualities. An outline summary of the acid-base e-module based on problem-based learning through Google Classroom contains a glossary, basic competencies, competency achievement indicators, instructions for using e- modules, concept maps, learning activities 1, 2, and 3, evaluation and answer keys.

Abstract

This type of Research & Development research aims to develop and produce interactive multimedia (MMI) on hydrolysis materials in a valid, practical and effective discovery learning model. Adapting the ADDIE model, the analysis pays attention to curriculum aspects, student characteristics, and media needs. The design is carried out based on analysis by making an outline of the media content, learning descriptions, lesson plans and LKPD. The development stage consists of pre-production where multimedia flowcharts and media scripts are produced, production where MMI prototypes are produced, and post-production for reviewing MMI before use. The implementation is carried out on students of class XI SMAN 1 Simboro even semester year 2020/2021. Formative evaluation with a validation process on all devices, including research instruments, namely learning implementation sheets, teacher and student response questionnaires, and learning outcomes tests. The results showed that all devices met the very valid criteria with a score of 3.58 and 89.58% very feasible. MMI is valid with a score of 3.12 and 78.08% is feasible. Learning is carried out entirely with a score of 1.80 based on discovery learning syntax and 89.93% is very practical. For the teacher's response, a score of 3.39 was obtained with practical criteria and the student response with a score of 3.55 met the practical criteria. The percentage of class completeness, based on the results of the learning test, reached 86.67% which was very effective. This shows that the developed MMI meets the specified validity, practicality and effectiveness qualities.

Abstract

The study aims to analyze students' misconceptions using a three-tier diagnostic test on acid-base material. The type of research used in this study is descriptive research. This research was conducted at SMAN 1 Mamuju to grade XI MIPA students. Data collection techniques employed diagnostic test in the form of multiple-choice stratified. The first level contained the students' answers, the second level was the reason for the answers, and the last level was the level of confidence. Data analysis was conducted by looking for the percentage of misconceptions from each concept in Acid-Base materials, namely the concept of acid-base theory, pH indicators of acid-base solutions, strength of acids and bases, and calculation of pH of acid and base solutions. The results show that the category of students' misconceptions on acid-base materials using the three-tier diagnostic test instrument is the M1 category. In this category, students answered incorrectly at the first and second levels but were sure that the answers at both levels were correct. The percentage obtained in the M1 category is 33.87% with moderate category. Students' misconceptions occur in the concept of acid-base theory according to Bronsted Lowry with a percentage of 70.33% in item 4 and 73.08% in item 18. The concept of pH indicator of acid-base solutions with a percentage of 73.08% in item number 9 while for the concept of the strength of acids and bases with a percentage of 76.36% in item 9. For the concept of calculating the pH of an acid-base solutions, 3 items are obtained that fall into the category of high misconceptions, namely item 14 with a percentage of 83.52%; item 16 with a percentage of 82.42%; and 20 items with a percentage of 78.02%. The causes of misconceptions in students are due to the incomplete reasoning, students' abilities, students' interest in learning, and teacher’s teaching methods.

Abstract

Problem based learning is a learning model that can improve students' attitudes. This article aims to review the results of the problem based learning model in improving the scientific attitudes of students in chemistry subjects. Problem based learning is a series of learning activities that emphasize the process of solving a problem faced scientifically. The method of writing in this article uses meta-analysis, by comparing information in the form of the pretest and pottest values in several similar articles. Based on the results of the analysis of several articles collected, the problem based learning model is able to improve scientific attitudes in chemistry subjects. The results of the comparison of the average increase of the 18 articles that were observed obtained a value of 18.27%. The paired sample test results obtained an average pretest of 56.03 while the average posttest of 74.29. Another result of the effect size test is that it is 1.390 in the strong category. The results of this article indicate that problem-based learning can effectively improve students' scientific attitudes in chemistry subjects.

Abstract

The purpose of this study is to determine whether or not there is an influence of Quipper School e-learning media on a problem-based learning model to increase motivation and learning outcomes of students in grade X MIPA 1 at MAN Sidenreng Rappangin Chemical Bonding subject. This research is a quasi-experimental research, quantitative with experimental research methods. The design used in this study was a randomized pretest-posttest design. The data obtained were analyzed by employing descriptive and inferential statistical analysis by using SPSS version 15. From the data analysis, it is discovered that the average value of motivation and learning outcomes of the experimental class is greater than that of the control class. In addition, from testing the T test hypothesis, a significance value of 0.001 < 0.05 is obtained for motivation and 0.000 < 0.05 for learning outcomes, which means that motivation and group learning outcomes using the Quipper School e-learning media on the PBM model have an influence compared to the group without using the Quipper School e-learning media on the PBM model.
