Abstract
This study aims to produce a performance assessment model in the form of tasks and rubrics on experimental electrolysis for high school students that are valid, reliable, and practical. The method used in this research is the development and validation method with participants as many as 12 students of class XI MIPA in one of the public high schools in Bandung City. The instruments used are interview sheets for preliminary studies, grid sheet, validation sheet, student worksheet, observation sheets that refer to 6 skill indicators, 29 tasks (performance aspects), and rubrics on experimental electrolysis using google form, and a practicality test questionnaire. The results showed that the performance assessment model in experimental electrolysis has four stages, namely the planning, development, validation, and limited trial stages. Content validity for tasks and rubrics seen from the CVR value showed that 29 tasks were declared valid based on suitability with indicators of hands on and minds on skills, while 28 tasks were declared valid for suitability with rubrics. For reliability, 15 tasks were obtained in the excellent category, 13 tasks in the good category, and 1 task was acceptable, and had a practicality value of 3.8, and could be classified as a very practical performance assessment model. Based on the results of validity, reliability, and practicality values, the developed tasks and rubrics can be used as a performance assessment model in experimental electrolysis for high school students.
