Validity of physics e-handouts based on the STEM approach to improve students’ knowledge competency

Abstract

Physics e-handouts based on the STEM approach to improve students’ knowledge competence is able to facilitate students to increase knowledge optimally. Before using this e-handout, an e-handout feasibility test is needed. The purpose of validation is to determine the suitability of e-handout with physics learning material by using the Aiken’s V formula by 4 validators. Data collection by questionnaire method. Validation is assessed from 3 aspects, first the Material Substance Eligibility with a value of 0.80 is a valid category, secondly a visual display worthiness obtained of a value of 0.85 with a valid category. Third, the feasibility of the learning design obtained a value of 0.81 with a valid categorization. The overall conclusion is that the validity value of the physics e-handout based on the STEM approach is 0.82 with a Valid category. So that e-handouts are appropriate to be used in physics learning to improve the competency of high school students’ XI knowledge.
