What is The Practicality and Effectiveness of Multiple Representations Based Teaching Material to Improve Student’s Self-Efficacy and Ability of Physics Problem Solving about?

## Abstract The objective of this research was to find out the practicality and effectiveness of multiple representation based teaching material to improve student’s self-efficacy and ability of physics problem solving in static electricity material. This was a quasi-experiment research by using pretest-posttest control group design. Samples were taken by using purposive sampling. Samples were grade XII students in Public Senior High School 15 (SMAN 15) in Bandar Lampung, YP UNILA Senior High School in Bandar Lampung, and Public Senior High School 2 (SMAN 2) in Kalianda. Instruments used were observation sheets for teaching material implementation, students’ response to teaching material, student’s activity sheet, self-efficacy sheet, and problems for student’s problem solving ability test. Data were analyzed by using descriptive analysis with percentage, N-gain analysis, and independent t-test. The research results showed that multiple representations based teaching material were: 1) practical to use in learning, and it was shown by (a) the average implementation of teaching materials in each learning activity, and (b) positive student’s response in using teaching materials; 2) ef
