Abstract

Soil damage due to excessive use of chemical fertilizers on potato vegetable crops is a real problem that must be solved. Through science learning with the Science Technology Society (STS) approach through the use of potato skins as organic fertilizer, it has helped reduce the use of chemical fertilizers. This study aims to foster scientific literacy in the area of awareness and concern for the environment. The research was conducted in class VII MTs Ma'arif Kejajar Wonosobo. This type of quantitative research with a true experimental approach pre-test-post-test control design. For data collection techniques with a questionnaire to see the attitude of awareness and concern for the environment. Data analysis was performed by t test. The results of the study showed that the t-test = 2.6> t table = 1.7. Science learning with the STS approach has a significant effect on scientific literacy in the area of awareness and concern for the environment.

Abstract

The low problem-solving skills of students and the lack of ability of students to apply the physics concepts they have learned in real life have encouraged researchers to develop electronic teaching materials containing traditional South Kalimantan games. This research is expected to be able to obtain valid, practical, and effective electronic teaching materials so that they are feasible and can be applied in training students' problem-solving skills. This study uses the ADDIE model and includes the type of research and development (R&D). The development was carried out in a field test at SMA N 6 Banjarmasin. Data collection is done using validation instruments, learning implementation sheets, and learning outcomes tests that are combined with problem-solving skills. The data were analyzed by quantitative descriptive analysis where the results obtained showed that: (1) electronic teaching materials containing traditional games obtained valid categories (2) electronic teaching materials including practical based on the assessment of the implementation of the lesson plan meet the practical category; and (3) the electronic teaching materials developed are also effective because n-gain of 0.78 is in the high category. Thus, electronic teaching materials containing traditional games developed are feasible to train students' solving skills in learning physics.

Abstract

Physics is a subject related to the environment so that it requires students to study nature and apply it in life. However, in learning sometimes students have difficulty understanding physics concepts and cause students to experience misconceptions. Therefore, a two-tier multiple choice diagnostic test is needed to analyze students' misconceptions. This study aims to determine the effectiveness of the two-tier multiple choice diagnostic test to analyze students' misconceptions in terms of content validity, practicality, and effectiveness. The research model is instrument development. The research design used is true experiment research with pretest posttest control. The subject of this research is class X MIPA MA Negeri Purworejo. Data collection in this study used validation sheets, observation sheets, student response questionnaires, and two-tier multiple choice diagnostic tests. The results showed that: 1) content validation for the construct and language aspects obtained from 3 validators got an Aiken V index of 1 for all items included in the high validity category, 2) a practical two-tier multiple choice diagnostic test in terms of sheets. observations with reliable categories and good responses and responses from students, 3) student learning outcomes have increased with an N-gain of 0.5 which is included in the medium category and students' misconceptions are found on the subject of momentum, impulse, and collision by 41.20% which is at medium level. Thus the two-tier multiple choice diagnostic test is declared valid, practical, and effective so that it is feasible to analyze students' misconceptions in learning physics.

Abstract

This study aims to develop a STEM-based Student Worksheet (LKPD) through Guided Inquiry to Improve Students' Science Process Skills. This research and development method refers to the Borg & Gall model up to the 8th stage, namely a trial use that has been adapted to research needs, namely developing LKPD and seeing an increase in students’ science process skills after using LKPD in learning activities, with research subjects in class XI IPA 5 and XI. IPA 3, each totaling 24 students. The results obtained are: 1) the validation of the LKPD that has been developed is "very valid" with the percentage of material experts at 82.36% and the percentage of media experts being 82.44%; 2) the feasibility of the developed LKPD is very feasible with a percentage of 95.43%; 3) The LKPD developed is declared practical because the response questionnaires from students are categorized as practical 4) the results of students' responses to the use of "very good" trials with a percentage of 87.33%; 5) The effectiveness of LKPD is seen from the achievement of students' science process skills with an N-Gain value of 0.78 or with a percentage of 78% overall very good and increasing in every meeting. It was concluded that the development of STEM-based LKPD through Guided Inquiry was valid and feasible and could be used in the Physics learning process to improve Students' Science Process Skills on Thermodynamic Materials.

Abstract

A study has been carried out on android-based waterwheel props used for dynamic fluid learning. The aim is to increase skills of critical thinking of students. The research subjects were 22 students of the sixth semester of Physics Education Study Program, Faculty of Teacher Training and Education, Muhammadiyah University of Purworejo. The implementation of the research is: before learning students are given a pretest of skills of critical thinking, then learning is carried out using an android-based waterwheel prop, then given a posttest with questions that weigh the same as the pretest questions. Furthermore, n-gain was calculated from the pretest-posttest tests of critical thinking skills, and analyzed by parametric and/or non-parametric analysis of statistical. The results of this study is a significant increase in skills of critical thinking at the 5% significance level with an average n-gain greater than 0.7 which means in the high category, and the Anova test produces a Sig score. of 0.342 which means it is greater than the probability score of 0.05 so that Anova test results show that there are similarities in the improvement of skills of critical thinking in the two learning meetings.
