E-Module Based on Role-Playing Learning Model with Scientific Approach to Improve Conceptual Mastery and Problem-Solving Skill on Fluid Dynamics

Fluid dynamics is the basic knowledge of technology development that is important to be mastered, but students still have difficulties with it. This research aims to determine the students’ increased conceptual mastery and problem-solving skills using ­e-module. The method of this study uses the quasi-experimental pre-test-post-test control group research design. Each student is given questions on pre-test and post-test conceptual mastery in multiple-choice and problem-solving skills in the form of descriptions. Student answers were analyzed with descriptive statistics, the Wilcoxon, and the n-gain tests. After the e-module was implemented, the increase in conceptual mastery of the experimental class was higher than the control class, with an n-gain value of 0.69 (moderate) for the experimental class and 0.46 (moderate) for the control class. The increase in the problem-solving skill of the experimental class was higher than that of the control class, with an n-gain value of 0.59 (intermediate) for the experimental class and 0.28 for the control class (novice). So, this e-module can improve students' conceptual mastery and problem-solving skills. The reason is caused by the learning process of experimental students who can learn actively, independently, intensively, and repeatedly using the e-module for conceptual mastering by the stages of the scientific approach through role-playing.

Penggunaan Laboratorium Virtual Materi Laju Reaksi untuk Meningkatkan Hasil Belajar Siswa SMAN 3 Muaro Jambi

Reaction rate material is one of the materials from the Chemistry eye in high school which studies the concept of reaction rate, the factors that affect the reaction rate and purchase order of the reaction. In learning the goal is to say that mastery of concepts by students is through experiments/practicums, the same is the case with acid-base materials and other chemical materials. To realize the demands of the learning objectives of the reaction rate, practicum is needed. The purpose of community service is due to the limited tools and materials in the laboratory, so that the chemical practicum, especially the reaction rate, is not carried out. The ability of teachers in the field of ICT is very low, so teachers cannot operate and create virtual laboratories.

THE IMPORTANCE OF MASTERING MATHEMATICAL CONCEPTS IN SOLVING MATHEMATICAL PROBLEMS IN ELEMENTARY SCHOOLS

Teachers realize that mathematics is often considered a subject that is less desirable, feared, and avoided by most students. Various alternatives are used by teachers in learning mathematics, both the mathematical approach and the methods used so that students can master mathematical concepts and can solve problem solving problems. The purpose of this article is to describe the importance of mastering mathematical concepts in solving elementary math problems. Mastery of mathematical concepts is the basis for being able to solve mathematical problems with higher order thinking. In basic education students are directed to have cognitive abilities, namely analyzing (C4), evaluating (C5) and even creating (C6). These abilities are closely related to many of the questions that lead to solving mathematical problems. So that the teacher trains students to be able to solve mathematical problems, where students must have the ability to master mathematical concepts.

Virtual Laboratory in Physics Education: Penguasaan Konsep Mahasiswa dalam Mata Kuliah Fisika Inti

Virtual Laboratory (V-Lab) is a media platform for interaction and visualization of learning for practicum-based courses. V-Lab is a solution to learning problems due to the lack of real laboratory facilities as well as an alternative for practicums that require a high level of safety. The purpose of this study was to determine students' mastery of concepts after using the V-Lab in the core Physics course. The method used is quasi-experimental. The research subjects were 15 Unuha physics education students. The data collection technique is a concept mastery test. The results showed that the increase in mastery of the concept was 0.432 with moderate criteria, while based on the paired sample test, it was known that the sig. (2-tailed) is 0.000 <0.05, then Ho is rejected and Ha is accepted. So it can be concluded that there is an average difference between pre-test and post-test concept mastery, which means that there is an influence of V-Lab application in increasing mastery of core physics concepts. The data shows that the Virtual Laboratory is effectively used to improve mastery of the concepts of core physics courses.
