Development and Evaluation of the Effectiveness of Computer-Assisted Physics Instruction.

This study aims to design and develop an interactive software for teaching and learning physics about motion and vectors analysis. This study also assesses its effectiveness in classroom and assesses the learning motivation of SMA Pekanbaru’s students. The software is developed using ADDIE Model design and Life Cycle Model and built using the program Delphi Seventh version by considering design, technical, pedagogical, and the content of its learning material. The research was conducted through quasi-experiment upon XI grade students of SMA Pekanbaru. The evaluation of the software was done by the experts of design, pedagogic, technical, and learning material. After the evaluation, this software was also evaluated by expert users consisting of 31 experienced physics teachers from senior high schools in Pekanbaru. The population consisted of six classes XI grade students of SMA Pekanbaru, where two of them are randomly selected. One of the two classes, then, was determined as experimental group while the other as control group. The experimental group consisted of 38 students, with 19 boys and 19 girls whereas the control group consisted of 37 students with 17 boys and 19 girls. The sampling was based on homogeneity and normality test. The finding shows that the reliability based on Cronbach Alpha is ?=0.740. Learning physics using interactive software “Motion and Vector Analysis” has affected students’ conceptual understanding by 81.16 compared to students learning using traditional method, which was only 35.86. Through t-test, it was found that students’ conceptual understanding was different from value t= -22.725, p= 0.00 with ?= 0.05. Students’ motivation to learn in the post-test was better for students who learn using the software than those who learned using traditional method. Finding based on gender found that the conceptual understanding of male students and female students were similar. Learning motivation for both male and female students has also increased. Therefore, learning physics with “Motion and Vectors Analysis” topics using interactive software is more effective than learning using traditional method.
