Abstract

This research purposed to find outthe increasement of students’ achievement which taught by using guided inquiry-based model higher than conventional model, the increasement of students’ science process skill which taught by using guided inquirybased model higher than conventional model, and the significant correlation between students’ achievement with science process skill by implementing guided inquiry-based model. The population of this research is all students of natural science elevent grade SMA Negeri 1 Binjai in the year academic of 2017/2018. Analysis technique was done by using gain test, normality test, homogeneity test, right-sided t-test, and correlation test. As result: 1) the increasement of students’ achievement which taught by using inquiry-based model is higher than the conventional model with t-table (1.666) > tstatistics (3.700) for cognitive domain, t-statistics (4.208) for affective domain, and tstatistics (4.798) for psychomotor domain, 2) the increasement of students’ science process skill which taught by using guided inquiry-based model is higher than conventional model with t-statistics (4.376) > t-table (1.6663), 3) there is significant correlation between students’ achievement with science process skill by implementing guided inquiry-based model with very high criterion respectively 0.900, 0.860, and 0.819 for cognitive, affective and psychomotor domain.
