The Effect Of Using The Guided Inquiry Model Assisted By Student Worksheets On The Digestive System In Human

Abstract

This research was inisiated by the low test results of students in various schools, especially SMPN 40 Padang, which was caused by the application of a learning model that was not suitable for the students' conditions. This study aims to determine the effect of using the Guided Inquiry learning model on learning outcomes of the human digestive system in class VIII students of SMPN 40 Padang. The research design was a quasi-experimental and posttest only non-equivalent control group design. The population of this study were all students of class VIII SMPN 40 Padang consisting of 5 classes with a total of 427 students. The sample for this study used a random sampling technique, so that the selected sample was class VIII₃ as the experimental class and class VIII₄ as the control class. Data collection used cognitive learning outcomes tests, objective questions and psychomotor assessment sheets that had been validated previously. The results showed that the average value of learning outcomes in the experimental class was 58.8 higher than the control class, which was 42. The results of the hypothesis test used the t-test with t_count (4.670) > t_table (1.677) at a significant level of 0.05 so that H₀ was rejected and H_a accepted. Based on these results, the application of the Guided Inquiry learning model has positive effect on students learning outcomes on the topic of digestive system at SMPN 40 Padang.
