Development of two-tier multiple choice instrument to measure science process skill

Abstract

The science process skills of students are inseparable from learning. To measure the science process skills of students required an instrument of assessment that is easy and appropriate. This study aims to measure the ability of science process skills of students in secondary schools, using two-tier multiple choice instruments. Indicators of the science process skills used are interpreting data, predicting, asking questions, formulating hypotheses, planning experiments, using tools and materials, applying concepts, and communicating. This two-tier multiple choice assessment instrument consists of two tiers, where first-tier is a matter of knowledge that indicates science process skills and second-tier is the reason for the answer in the first-tier. This assessment instrument consisted of 18 questions, and was given to grade XI of Madiun 4th high school. The results of this study indicate the science process skills of students in SMA 4 Madiun included in the medium category with an average value of 37.12%
