Abstract

The goals of this study are 1) Produce recitation multi contexts program based on PPT at vector material to improve students physics conceptual understanding- 2) To know the effectiveness of using recitation program which is developed to improve students understanding at vector. The development model of this media is 4D with the subject study are 65 college students educational of physics at 5th semester, 17 college students physics at 3rd semester who has learned vector material, and 26 college students of educational of physics at 1st semester who are learning fundamental of physics at Unniversitas Negeri Malang. The results of this study show, 1) There are 26 questions multiple choice with feedback at every option and variation question context at recitation program based PPT- 2) Validator results show that visual and content of recitation program developed have percentages 90,6% (very interesting) and 85,0% (very valid)- 3) Based on the college students respond through a questionnaire about the usability of recitation program show that it was very useful for college students to improve conceptual understanding- 4) The result of a questionnaire about college students perception show percentage 99,2% (very easy to be understood). Furthermore, the implementation result shows 1) Students conceptual understanding of vector material significantly increased after using recitation program with t score -50,722 and p score 0,000- 2) The effect of this media to the students conceptual understanding is very strong which is shown from N gain 0,64 and d effect size 6,29. Nevertheless, in this study was found that college students still have an incomplete conceptual understanding of the sub topic vector component. It happens because they add vectors by using algebra rules, not vector rules.
