Abstract

The low mastery of physics concept was caused by a lack of experimental abilities in the learning process. Levels of Inquiry (LoI) is an appropriate step for develop experimental abilities because it has a systematic, structured stages, and it can flexibly applied to the various dominancy of students and teachers role according to conditions. This study was conducted to observe students sound wave concept mastery improvements after the implementation of LoI in learning. The study used one group pretest-posttest design, wich involved 152 students in one of public junior high school in Bandung. Instrument used in this study was descriptive concept mastery test. Data were analyzed using t-test and normalized gain to determine the improvement of students concept mastery. The results showed that students sound wave concept mastery improvement was improved by Levels of Inquiry in overall (<g> = 0,38). The results also included detailed analysist of students concept mastery development by general, each cognitive aspect and each sub matters of lesson. Based on the results, Levels of Inquiry (LoI) implementations can improve the students concept mastery on sound wave.
