IMPLEMENTATION OF GUIDED INQUIRY WORKSHEET ON THE TOPIC OF ATOMIC STRUCTURE QUANTUM MECHANICS ON GRADE X

Students are required personally to be more active through observing, questioning, collecting data, associating and communicating in the 2013 curriculum. One of the learning model that implements the curriculum 2013 is guided inquiry learning model. Guided inquiry learning model is a model student-centered learning, students work in small groups with individual role to ensure that all students are fully engaged in the learning process. To support the implementation of guided inquiry learning model implemented in small groups, the use of guided inquiry worksheet. Guided inquiry worksheet is made based on guided inquiry learning cycle consisting of five stages of orientation, exploration, concept formation, applications and closing. This research is experimental research, the design Randomized Control Group Posttest Only Design. The study sample consisted of two classes,experimental classes and control classes were obtained through simple random sampling technique. Based on the test results obtained by the average value of the experimental class (58.39) was higher than the control class (48.71). Results of tests of normality and homogeneity of the final test results obtained that both classes normally distributed and homogeneous samples. Data analysis was performed using t-test at the 0.05 significance level obtained tcount = 5.12 and ttable = 1.67. Based on the analysis shows that the learning outcomes of students who use guided inquiry worksheet is significantly higher than the learning outcomes of students who use general worksheet on the topic of atomic structure quantum mechanics on grade X.
