Validity of interactive student worksheets based on inquiry based learning models to improve knowledge competence

Physics learning activities have not been carried out optimally as seen from the low competency of students’ knowledge. This is due to the lack of available teaching materials that fit the needs of students, the available teaching materials are very limited because they do not take advantage of technological developments and there is no model in them, so learning is not entirely student centered. Utilization of technology is one of the efforts to facilitate learning in accordance with the needs of students by developing non-printed teaching materials in the form of interactive student worksheet based on inquiry based learning models. The purpose of this research is to produce an interactive student worksheet based on a valid inquiry based learning model. This type of research is research and development using the ADDIE model. The method used in this research is descriptive statistics. The validity of the interactive student worksheet is assessed by three experts using a validity questionnaire. The validity of the interactive student worksheet is analyzed using the Aiken’s V. formula. The validation results show that the material validity aspect is 0.87; visual display 0.89; and learning design 0.85. Based on the analysis of the validity of interactive student worksheets data, an average of 0.87 is in the valid category. Thus, Interactive Student Worksheets based on inquiry based learning model can be implemented in physics learning to increase knowledge competence.
