Abstract

This study aims to determine the validity of the instrument and determine the level of effectiveness of the development of assessment instruments for learning outcomes of cognitive aspects based on scientific approaches to dynamic fluid material based on the assessment of experts, teachers and class XI students of SMA Negeri 1 Stabat. The type of research used is research and development (R&D) using the 4-D model. The subjects in this study were 2 expert lecturers, 1 physics teacher, 9 small group test students and 33 large group test students. The object of this study is the validity and effectiveness of the instrument. The results of the experts' assessment showed the Aiken V index of 0.95 (good validity). The results of the validity of a small group test, 15 valid questions, and effective questions. While the results of the validity of a large group test, 12 valid questions, and effective questions. Then the development of student learning outcomes assessment instruments based on a scientific approach to class XI dynamic fluid material gets decent criteria and excellent assessments based on the criteria of experts, teachers and students.Keywords: assessment instruments, learning outcomes, scientific approaches, dynamic fluids

Abstract

Development of test instruments is the process of developing tools or procedures used in the framework of measurement and assessment activities. This study aims to develop well-qualified questions including validity, reliability, difficulty index, and differentiation. This research is a research and development with a development process using a 4D development model developed by Thiaragajan, et al (1974) covering four stages, i.e. : Define, Design, Development, and Disseminate, which in this study was only conducted up to 3D (development stage). The definition stage is performed student analysis, material analysis, and objective analysis. The design stage is the preparation of tests and the selection of test formats. The development stage consists of instrument preparation, expert validation and product trials to students. The test instruments developed are assessed according to the indicators and aspects of validation so that they are declared valid by the validator. The reliability value of the test instrument developed is 0.66 which belongs to the category of moderate reliability. Furthermore, the level of difficulty obtained is 8 medium questions and 2 easy questions, and the differentiation obtained is 7 enough questions and 3 good questions. The developed test instruments are acceptable and eligible to be used as test results of students' learning results on sound wave materials in grade 11 of high school.
