IMPLEMENTATION OF STUDENT WORKSHEET BASED ON GUIDED INQUIRY ON THE TOPIC OF MOLECULAR GEOMETRY IN GRADE X

This study aimed to reveal the differences in student learning outcomes by using two worksheets, among student learning outcomes by using guided inquiry-based worksheets with MGMP worksheets that usually use at that school . In the learning process by using guided inquiry learning model, students were guided to find the concept itself in small groups. The learning model matched with the demand of Curriculum 2013 which requires an active participation from the students through 5M activities (observing, asking, collecting data, associating and communicating). This research was a Quasi Experimental Research by using an expanded Randomized Control Group Posttest Only Design. The samples of this research consisted of two classes; 1st experimental class and 2nd experimental class which were formed through cluster sampling. Based on the test results obtained by the average value in the knowledge competence, the 1st experimental class' result (65.34) was higher than the 2nd experimental class' (45.16). Both of Normality and Homogenous's results showed that the distribution of the two experimental classes were normal and homogeneous, the data analysis which was performed by using t-test. Based on the analysis, it showed that there were significant differences in learning outcomes among the students who used guided inquiry-based worksheets and MGMP worksheets on molecular geometry material.
