E-Diagnostic Based on Multirepresentation to Know Cognitive Ability in Excretion System Learning

Abstract

Pandemic requires educators to be more creative in presenting online learning so that students can receive learning well. The researcher developed an E-diagnostic test, the presentation of the questions contained a representation of the Excretory System material. This study aims to determine the feasibility of multi-representation-based E-diagnostics in measuring students' cognitive abilities. The type of research used is the development (Research and Development) by adopting the stages. The research was conducted in seven stages: potential and problems, data collection, product design, design validation, design revision, product testing, and product revision. The research instruments were in the form of interview sheets, validation sheets, and test results. Data collection techniques in the form of interview sheets, validation questionnaires, and tests. Data analysis in this study included: learning outcomes tests, item validity, and item reliability. The results of the study were in the form of test results for students of class XI IPA-A and XI IPA-B who scored above the average of 20 from each class. The test results of the validity of the questions from the validator's assessment are 2.66 with quite valid criteria and the question instrument that shows more than 0.3 is included in the valid category. The result of the product moment correlation test is 0.6 with a strong category. The results of the reliability test of more than 0.60 are categorized as reliable so that based on the test results, the test is feasible to use in knowing the cognitive abilities of students.
