Abstract

This study aims to develop an assessment instrument based on science process skills. The research method used is Research and Development (RD). Based on feedback from students, this assessment instrument has a 84% rate the attractiveness and readability level of 86,39%. Based on feedback from teachers, this assessment instrument has a readability level of 81,33% and 84,44% level according to the contents. Constraints faced in the development of assessment instrument is the difficulty in developing matter to measure the science process skills (observing, classifying, predicting, inferring, and communicating), the difficulty in making images submikroskopis, and the lack of reference to make matters enrichment that can measure the skills process of science students. Penelitian ini bertujuan untuk mengembangkan instrumen assessment berbasis keterampilan proses sains.
