Abstract

This study aims to develop a performance assessment model through self-assessment
techniques possible to measure students' science process skills in science-based
inquiry teaching learning process. The research used simplified design of Research
and Development from needs analysis, product development stage, and validation.
Validation score indicates three aspects; usefulness 80%, model construction 83.33%,
and readability model 81.67% all rated as very good criteria. In addition, the results
of questionnaire about the implementation of the model obtained positive approval
from the users. The results show that the measurement model is uniquely useful to
measure the student skills of science processing in a junior high school level.
