Analysis of Students' Science Process Skill of Junior High School in Ngawi District in Material Classification and its Changes

摘要

This study aims to determine the science process skills in material classification and its changes 7th grade of junior high school in Ngawi. The method used in this research is quantitative descriptive. The sample of this research is taken by stratified random sampling technique. The initial profile of science process skills is analyzed from 51 state junior high schools in Ngawi with sampling proportion 10% in each strata. The sample which were used were 93 students from 3 schools which is include high categorized (SMPN 2 Ngawi), medium categorized (SMPN 2 Karangjati, SMPN 3 Karangjati, SMPN 1 Pangkur) and low categorized (SMPN 3 Ngawi). Technique of data collecting was written test in form of multiple choice. The result of this research from aspect science process skill was: 1) observing was equal to 88, 17%,2) classifying was equal to 72,60%, predicting was equal to 23,77%, communicating was equal to 44,97%, measuring was equal to 60,41%, inferring was equal to 28,72%, designing experiment was equal to 46,76%, interpreting data was equal to 42,31%, defining operationally was equal to 27,58%, formulating models was equal to 49,99%, controlling variables was equal to 25,39% and formulating hypotheses was equal to 43,91%. From those data, can be concluded that the science process skills of students in 7th grade junior high school needs to be improved, especially in predicting, communicating, inferring, designing experiment, interpreting data, defining operationally, formulating models, controlling variables and formulating hypotheses.
