INQUIRY AND BLENDED LEARNING BASED LEARNING MATERIAL DEVELOPMENT FOR IMPROVING STUDENT ACHIEVEMENT ON GENERAL PHYSICS I OF MATHEMATICS AND NATURAL SCIENCE OF STATE UNIVERSITY OF MEDAN

The aim of this research is to determine if inquiry and blended learning based materials can improve student’s achievement. The learning materials are: book, worksheet, and test, website, etc. The type of this research is quasi experiment using two-group pretest posttest design. The population is all students of first year who take general physics I. Samples which are taken using cluster sampling techniques are two classes from physics department and two classes form chemistry department where one class for experiment and one class for control class of each department. It was found that student’s achievement using these materials (76.04) is significantly higher than those using conventional materials (68.18).
