Analysis of Performance Assessment Instrument Students on Simple Harmonic Motion Practical Work in Physics Senior High School Magister of Physics Education, Faculty of Mathematics and Sciences, State University of Jakarta Abstract This study aimed to determine whether the performance assessment instrument used in a simple harmonic motion practical work created by the teacher is feasible or not from the expert validation with aspects of construction, materials and language. The method of this research was qualitative research using Miles and Huberman model, which consists of four stages: 1) Data Collection, 2) Data Reduction, 3) Data Presentation and 4) Conclusion Drawing. The place of research was conducted at State University of Jakarta and Bintara Depok Senior High School in 2018. The assessment instrument to be used in this research was performance assessment instrument. Meanwhile, to review the performance assessment instrument used questionnaire format in the form of a questionnaire. Data collection techniques used documentation techniques (drawings) and questionnaires. The performance appraisal instrument used will be validated using peer-reviewed format (15 teachers) of construction, material and language aspects. The result of validation test of performance assessment instrument that used, got score 80 from material aspect, 82,50 from construction aspect, and 88,75 from language aspect. Based on the scoring criteria, the student performance assessment instrument on a simple harmonic motion practical work in Senior High School from the construction aspect was very good, the material aspect was very good, and the language aspects was very good. Validation test results with an average score of 84 were in the range of ≥80 so that the instrument was interpreted very well. Based on these results, the performance assessment instrument on a simple harmonic motion practice material used by teachers was worthy of use to measure learners performance.
