INNOVATIONS IN ASSESSING STUDENTS’ DIGITAL LITERACY SKILLS IN LEARNING SCIENCE: EFFECTIVE MULTIPLE CHOICE CLOSED-ENDED TESTS USING RASCH MODEL

Abstract

This research goal to develop a multiple-choice closed-ended test to assessing and evaluate students’ digital literacy skills. The sample in this study were students at MTsN 1 Blitar City who were selected using a purposive sampling technique. The test was also validated by experts, namely 2 Doctors of Physics and Science from Yogyakarta State University. The test instrument was developed based on five aspects of digital literacy skills: information, communication, content creation, security and problem-solving. Data have been analyzed descriptively and inferentially using the Rasch version and the assist of Quest software. The results showed that eight multiple-choice closed-ended test instruments were declared valid based on expert validation with an Aiken V value of 1.00. The reliability result is 0.97 with a very high category, and the INFIT MNSQ standard deviation value is 0.86 - 1.16, so seven items are by the Rasch model. Thus, the seven items in the multiple-choice closed-ended test instrument can be used to assessing and evaluate students’ digital literacy skills in learning science.
