Abstract

Performance assessment instruments so far were still general, not specifically assessing expected performance in each practicum. This study was aimed to develop instruments to assess generic science skills in basic chemistry practicum. ADDIE development model was used as a methodology in this research with data collection methods through observation and questionnaires. The subjects of this study were 3rd-semester students taking basic chemistry practicum courses at the University. Instrument validation was done by content analysis and reliability test between the rater as the methods to reliability test of the rubrics. The results of validity and reliability tests showed that the instruments meet valid and reliable criteria for the assessment instruments of generic science skills, especially direct observation skills, symbolic language, and logic inference in basic chemistry practicum. The reliability test showed the average value of interclass correlation coefficient (ICC) in the redox and electrochemical practicum was 0.780; in chemical kinetics practicum 0.660; and in the functional group introduction practicum 0.639. The results of the feasibility test showed that the percentage of positive responses was 92.08% and negative responses were 7.92%, so it can be stated that the product received a positive response. Based on the results of the study, the assessment instruments developed were declared to be suitable as assessment instruments.
