Digital Literacy Test: Development of Multiple Choice Test for Preservice Physics Teachers

Abstract

This study aims to develop a digital literacy test for preservice physics teachers. The development of the instrument was carried out in three stages: initial development of the test, verification of content validation, and examination of an instrument for item analysis. The test is developed by analyzing digital literacy competencies that can be trained in physics for school learning. There are 14 multiple choice items consisted the three competency areas, namely information and data literacy, communication and collaboration, and digital content creation. Content validation is verified by five learning evaluation experts using CVR (Content Validity Ratio). Examination of instrument involved 40 preservice physics teacher in a university in Tasikmalaya. The result of the study showed that the development of the instrument has a good level of validity and item analysis. The validity of each item is determined through the CVR where each item has a value of CVR 1. This shows that each item meets the critical CVR requirements for five experts so that each item can be verified valid. The average difficulty index is 0.55 with the acceptable category. The average discriminant index is 0.86 with a very good category. Test reliability was determined using a split-half technique and a reliability score is 0.70 with good reliability. 14 items of the digital literacy test can be used to measure the digital literacy of preservice physics teachers.
