LEARNING WITH GUIDED INQUIRY MODEL TOWARD THE UNIVERSITY STUDENT’S PROBLEM SOLVING SKILL ON KINEMATICS OF PARTICLE

The objective of this research is to test the effectiveness of the application of guided inquiry learning model to improve the problem solving skill of college student on kinematics of particle topic. The method of this research was quasi experiment with randomized pretest- posttest control group design.Sample of this research was the college student’s who taking the course on general physics I in Universitas Negeri Medan odd semester that consist of two classes which determined by cluster random sampling. One of the class as the experimental group by applying guided inquiry learning model and other class as a control group by applying conventional learning. Problem solving skill measured by using an essay test form that has been validated. Analysis technique of the effectiveness testing was the effectiveness of the application of guided inquiry learning model using gain test and different test. Based on the result of resaearch showed the average value of the control class was 22.52 and experimental class 20.60 The average value of posttest in control class was 59.89 and experimental class was 67.25. The result of the research showed that there was significant difference problem solving skill between college student that learned guided inquiry model compared to the conventional learning model. The raising percentage of problem solving skills by applying the model guided inquiry on kinematics of particle topic as 58% while the conventional learning as 48%, respectively in the medium category.
