Abstract

The purpose of this research is to find out the problem-solving physics by using media-based videoscribe learning. Learning with the help of a video will make students more interactive and active because students can understand the concept of abstract and solve the problem of physics related to daily life. The method used in this research was the quasi-experimental method with the research design of The Randomized Post-Test Only Control Group Design, which involved 30 students as samples in Physics Education of Indraprasta PGRI University.The technique analysis of the research using the T-test. The results showed that by using learning media videoscribe could improve the ability of problem-solving physics. We found significant positive effects of the use of videoscribe in conveying physics lessons With the help of video scribe, learning is more efficient in physics learning. The students understand abstract physics material and are able to activate students in learning. These findings are consistent with studies on the improve of the student’s problem-sloving ability on physics learning.

Abstract

Misconceptions in physics lessons are still the main problem faced by teachers and students. Misconceptions of physics occur at various levels of education and many physics materials at the high school level. The results of observation to class XII students in Semarang obtained data that the material on the theory of relativity is material with a low level of mastery of concepts. In addition, teachers also have difficulty in identifying physical misconceptions experienced by students.  Therefore, this study aims to develop an instrument in the form of a Four-Tier Diagnostics Test to identify students' physics misconceptions on the material of relativity theory, determine the level of validity, reliability, and characteristics of the four-tier diagnostics test. The type of research is Research and Development (R&D). The methods used are documentation, interviews, questionnaires and tests. The results showed that the instruments were valid and reliable. The diagnostic test consists of four levels, namely: a question with one answer key and four distractor, the degree of confidence of the answer, the reason, and the level of confidence of the reason. The resulting instrument consists of a grid, work instructions, test questions, answer keys, answer sheets, scoring guidelines, and result interpretation guidelines. Validity testing by expert validators shows the developed instrument is valid and reliable.
