EFFECTIVENESS IN USING INQUIRY-BASED TEXTBOOK OF PHYSICS FOR PHYSICS LEARNING IN VOCATIONAL HIGH SCHOOL.

This research aimed to describe the effectiveness in using inquiry-based textbook of Physics for Physics Learning in Vocational High School. The effectiveness was reflected by student learning outcomes and responses after the implementation of inquiry-based textbook of Physics. The research method was quasi-experimental research with design of One Group Pre-test Post-test. The subjects of the research were students of X Multimedia odd semester, Vocational High School Al-Qodiri Jember. Data collection techniques were the test of student learning outcome and questionnaire. Data analysis techniques used N-gain to analyze the improvement of the learning outcomes and percentage to determine student responses. The results showed that the N-gain score on the first, second and third learning material was 0.61 in moderate category; 0.74 in high category; and 0.72 in high category. Based on the data analysis of student response,the overall student response was 84% and it was in positive category. Based result of research,the conclusion is inquiry-based textbook of Physics was effective for Physics learning in Vocational High School as reflected by the average of N-gain score which was in high category and student responses were in positive category.
