Development of Three-Dimensional Light Wave Test Based on Three-Dimensional Learning Framework

Abstract

The three-dimensional learning framework as a current science learning standard to facilitate the development of students' knowledge that is coherent and interconnected so that it can be used in various situations of daily life, is only possible if the assessment is oriented towards the science learning standards in question. The focus of this research is to develop a Three-Dimensional light wave test based on the Three-Dimensional Learning Framework. Development was carried out through quantitative research methods with construction design and validation, involving physics lecturers, physics teachers and high school students. Construction and validation were carried out using document analysis sheets, cognitive questionnaires, content validation sheets and student responses. Analysis was carried out through descriptive analysis, V-Aiken content validation, and Item Response Theory (IRT) using eIRT software. The construction and validation results show that the Three-Dimentional light wave test based on the Three-Dimentional Learning Framework has differentiating power in the good category, five items are very high, three items are high, eight items are medium and five items are low; the level of difficulty is in the medium category, two questions are very difficult, seven questions are difficult, eight questions are medium and four questions are easy; the pseudo guessing factor overall functions well; and reliable for measuring the level of ability of students with low to very high abilities. The Three-Dimensional test of light waves based on the Three-Dimentional Learning Framework can be used by educational practitioners as an assessment tool to explore students' coherent understanding of disciplinary core ideas (DCI), scientific practices (SP), and crosscutting concepts (CC) in wave material light.
