Validity of development of student’s worksheet based on problem-based learning model on parabolic motion materials assisted by digital display practicum

Abstract

Physical Competence of students is not as expected. One of the causes is the use of teaching materials that are not in accordance with the established standards and has not maximized the use of practical tools that support the learning process. Therefore, it is necessary to develop student’s worksheet based on problem-based learning model using practicum with digital display. The purpose of this study is to analysis of validity development of student’s worksheet based on problem-based learning model using practicum with digital display. This type of research uses design research which ADDIE model. Technique used for analyzing the data was descriptive percentage. The result of this research is analysis of validity development of student’s worksheet. The result of validity instrument earned value V 0.90. The result of validity student’s worksheet earned value V 0,92. The result of analysis of validity practicum tool by comparing data obtained with actual data earned value 95%, this indicate a valid tool to use. Based on the result of the research, it can be concluded student work sheet based on problem-based learning model in the material of parabolic motion using practicum with digital display with a valid criterion.
