Validity and Practicality of the Students’ Worksheet Based Multiple Representations on Dynamic Electricity Material

Abstract

This Research has the purpose to get high validity and practicality on students’ Worksheet. The method used was research and development (R&D) following Borg and Gall's steps, which simplified into three phases: literature study, planning and development, and field test. Literature study phase was used to review the curriculum, do observation, review the relevant theory, determine the purpose, and interview the interviewees. The result of this phase produced early data related to students’ worksheet preparation. Planning and development phases were used to arrange students’ worksheet, lesson plan, making media, assessment, sheets of observation, questionnaire and validation expert sheets. This phase produced an early product of students’ worksheet based multiple representations through four steps. Field test phase was used to do a limited field test. Limited try out was chosen from one class, taken random sample proportionally. Data collection tools in this research were the observation sheet of students’ worksheet implementation, students’ activities, and students’ worksheet legibility questionnaire. Data were analyzed through descriptive analysis. In this stage, it resulted in the students’ worksheet which had high practicality shown by the high implementation of students’ worksheet, student’s positive response towards students’ worksheet based multiple representations.
