Development of authentic assessment that based on scientific approach to improve students' skills of science process in physics learning

Abstract

Authentic assessment is an assessment to measure and to report the progress of students' learning achievement continuously. These learning achievements were showed as score of cognitive, affective, and skill that are integrated each other. This study aimed to obtain the valid, practical, and effective authentic assessment that based on scientific approach. Developments of this authentic assessment referred to 4D model of Thiagarajan, i.e. define, design, develop, and disseminate. This study was held until the develop phase. The obtained authentic assessment includes lab worksheet, observation sheet of scientific attitude and science process skill, written test, and rubric of scoring. Data were gathered by using test, observation, and questionnaire. Analysis process included validity test of questionnaire, practicality test of teacher and students' questionnaire, and effectiveness test through written test, attitude and skill observation. Result of this study show that this authentic assessment is valid, practical, and effective in improving students' science process skill.
