Development and Validation of The Electronic Student Worksheet Assessment Instrument Based on The 4C Skills Oriented RADEC Lecture Model

Abstract

This study aims to develop an electronic student worksheet assessment instrument based on the RADEC model oriented to 21st-century skills: Critical thinking, Communication, Collaboration, and Creativity. This research uses a descriptive method with the research and development design of the A+2D model, namely, Analyze, Design, and Develop. The instrument was developed by considering the learning needs of 4C skills and the possibility of being taught through RADEC stages. Furthermore, the instruments that have been developed are validated by four expert lecturers for the feasibility and practicality aspects of the E-LKM instrument, which include validating the suitability of the RADEC model stages and the emergence of 4C skills learning. Data collection was carried out by filling out the E-LKM instrument assessment sheet. The assessment data were analyzed using Aikens content validity. The results showed that the content validity of the E-LKM feasibility and practicality assessment instrument was categorized as good, with an average value of 0.95. The E-LKM assessment instrument is feasible and can be used to assess E-LKM based on the 4C skills-oriented RADEC lecture model.
