Farel Razaq Wardhana — 2024-12-19

In physics learning, students are expected to be able to understand physics concepts thoroughly and be able to relate them to the phenomena they encounter. Based on SMAN 6 Pekanbaru, researchers highlighted that educators often find that students have concepts that are different from scientific concepts. So it is necessary to research on understanding concepts with the help of innovative learning models. The aim achieved is to determine the effect of Experiential Learning on increasing class XI students' understanding of concepts in light and optics. Quasi Experiment is the method used with a Posttest-Only Control Design. The results of the posttest understanding of concepts in the experimental class were superior to those in the control class. We can conclude that understanding of concepts in class XI light and optics at SMAN 6 Pekanbaru can be improved through the application of the Experiential Learning model.

Devicawati Devicawati — 2024-12-19

This study aims to analyze students' needs for teaching materials in disaster mitigation learning. This research method uses quantitative descriptive research. Then analyzed and described to answer the existing problems. The subjects of the study were 53 students of the Science Education study program, University of Bengkulu, semester V. The instrument used was a questionnaire, with 3 aspects (disaster mitigation, teaching materials and learning process) and 24 questions. The results of the analysis showed that 95% of students chose the need for education about natural disaster mitigation. 11% of students did not know the Evacuation Location (gathering point) for the earthquake disaster at the University of Bengkulu and 22% of students did not know the flow map showing evacuation signs at the University of Bengkulu, so teaching materials that contain this are needed. The teaching materials needed by students are interactive and easy-to-use teaching materials, the contents of the material are clearly described in accordance with the facts in life, teaching materials that are audio-visual based (there are videos and animations), equipped with things that need to be considered in disaster mitigation and have a suitable color combination.

Yaspin Yolanda — 2024-12-19

The research was carried out at PGRI Silampari University, Physics Education Study Program, from September to November 2024, based on the graduate output which required them to have problem solving competence, whether learning so far had built meaningfulness in learning (Deep Learning). This descriptive research uses a case-based learning method through lesson study for two cycles on campus involving 16 students as objects and 8 observers from fellow lecturers who observe the emergence of problem solving indicators, Sharing and Jumping Task indicators of students when solving cases on electrical circuits. Instruments include 1) sharing task and jumping task worksheets, 2) problem solving observation sheets, and 3) learning reflection sheets. To measure the increase in variables measured using N-Gain, the resulting data is then in the form of learning transcripts using TBLA (Transcript-based Lesson Analysis), the observation data is reduced and displayed graphically. Based on the results of open class observations for two cycles, it shows that there was an increase in students' problem solving skills during two cycles with an N-gain of 0.80 (high) so that the average problem solving skills of students were in the skilled category, while the Sharing and Jumping Task achievements of students with an N-Gain were of 0.88 (high) in the developing category. Furthermore, the results of peer lecturers' reflections and student reflections show that learning has adapted to learning needs (mindful), students think and are involved in the learning process (Meaningful) and students feel happy and satisfied in seeking deep understanding in a lesson (Joyful).
