Abstract

The significant influence of the 21st century brought a change in Physics learning. Students are required to have the skills to think, work, and live in the surrounding environment. To achieve 21st-century skills needed teaching materials that can support the learning process.With the presence of teaching materials, students are more active in building their knowledge and easy to understand the material provided. Teaching materials that can guide students with a productive task to practice is the student worksheet.

The validity assessment of the student worksheet is carried out by expert reviews. This research aims to determine the validity of the student worksheet using an inquiry-based learning model with a science process skills approach. The research conducted is design research using the Plomp model with the type of development studies, where validity is at the stage of development. The research instrument used a validity questionnaire to be filled by expert reviews, then analyzed using Aiken's V formula. The result of the validity showed that the student worksheet using an inquiry-based learning model with a science process skills approach having valid criteria with a value of 0.88. It means that the student worksheet is decent for use in Physics learning.

Highlights

  • Learning is a process to support the realization of educational goals

  • The component of the instrument validity assessment includes the appropriateness of the statement with the instrument lattice, the instrument can reveal the quality of the content, language, construction, and graphics of the student worksheet and lesson plan, and the instrument has clear and easy to use instructions in the assessment process

  • The assessment of content validity and construction validity based on its suitability with the components of the preparation and steps in student worksheets according to the syntax of inquiry-based learning model with science process skill approach

Summary

Introduction

Learning is a process to support the realization of educational goals. Students are allowed to develop their potential in attitudes, knowledge, and skills to live in their social environment (Kemendikbud, 2013).
