Students’ shortcoming in understanding various concepts of physics is often due to the lack of teaching media can promote student active participation in the learning process. This study aims to develop a valid and effective microcontroller-based physics learning materials as teaching media in enhancing conceptual understanding of free fall motion lessons. This learning materials is developed using the research and development (R&D) method. Effectiveness test of learning materials using pre-experimental research design one group pretest-posttest involve students of physics education program in STKIP SoE. Data collection techniques were done through validation sheets, observations, test questions, and questionnaire sheets. Validation of learning materials through expert testing shows that learning materials are in a valid category. The results of the study shows that learning materials have a positive effect in improving students' conceptual understanding. The effectiveness of the use of learning materials in improving students' understanding of concepts has been analyzed through the results of N-gain calculations which show a moderate score increase. Moreover, the practicality test of learning materials using a Likert scale shows that learning materials are very practical to utilize as teaching media.

Misconception is a concept contradicts with scientific definitions or definitions approved by experts of particular field. Learners’ misconception cannot be eliminated but minimized so they do not grasp incorrect concept which can be identified through diagnostic tests. A research had been conducted to identify physics student teacher misconception. The research was undertaken using qualitative method with survey design. The population covered whole physics major students with 30 students of 6^th semester as samples. Data collection was done by giving three tier multiple choice model of diagnostic test developed by Ambarwati on electricity, magnetism, and solar system materials. Data source of this study was primary data source since data was taken directly from research subjects. Data was analyzed using descriptive qualitative data analysis technique. The result showed that 18% students experienced misconception, 40% partially understood, 12% fully understood, and 30% did not understand concept. 20% misconception identification of electricity comprised static electric, determining physical quantity on circuit, defining electrical energy and power in daily life; 18 % magnetism material on how to make magnet or determining poles that affected electromagnetic induction; and 17% solar system material about characteristics of astronomical objects and emerging phenomena due to climate changing on earth surface. the identifications result implied a demand of developing and applying innovative, creative, and appealing learning in remediating and fixing misconception.

Nilai N-gain terhadap pemahaman konsep siswa diperoleh nilai rata-rata sebesar 0,82 dengan kriteria tinggi dan data terhadap respon siswa diperoleh nilai rata-rata sebesar 74,86% dengan kriteria Baik. Hal ini dapat disimpulkan bahwa bahan ajar berbasis kearifan lokal anyaman Nyiru yang dikembangkan valid sehingga dapat dijadikan sebagai salah satu sumber belajar dalam kegiatan pembelajaran fisika di sekolah.</em>

The objective of study was developing diagnostic test evaluation instrument in multiple choice form with predetermined reason to identify Grade VIII student’s misconceptions on force topic in SMPN Oenino. Population of the study covered all students whereas the samples were Grade VIII students SMPN Oenino. The research method was Research and Development (R&D) with potential and problem, gathering information, product design, product validation, product revision, and product trial. Validation phase included experts and content validation. On expert’s validation, test instrument was validated by 3 validators with 87,7% worthiness average and was recommended applicable without revision. On content validation, 45 test items were tried out to students and 17 items were declared valid ranging from C1 to C4 cognitive domain which were used later to identify student’s misconceptions. Their misconceptions on force material were 23%, 38%, 13% and 26% from C1 to C4 cognitive domains. The result indicated that this instrument was applicable to identify student’s misconception on force materials.

The purpose of this research is to increase students' motivation and cognitive learning outcomes through the application of physics learning media based on the game of snakes and ladders in senior high school class X related to the material of work and energy. The research method used is a pre-experimental type with a one-group pretest-posttest design research model. Data collection techniques are through test techniques for learning outcomes and questionnaire techniques for student motivation and responses. Data were analyzed based on paired sample t-test technique, N-Gain test, and percentage descriptive. The results of the research obtained an increase in students' cognitive physics learning outcomes based on the results of the t-count score smaller than t-table, a large increase of 38.39% (medium), student learning motivation increased from good category (78.63%) to very good (88.47%), while the students' responses were categorized as very good. Therefore, the use of snakes and ladders game media is effectively applied for learning in SMA class X on the material of work and energy.
