In this work, we examine the learning experiences of 9 secondary school students throughout a short course about the physics of sound in a computer-based learning environment rich in representations and focused in student's inquiry. Students worked in group of three people, and each group studied the text in their own pace. At the end of each section of the text, the groups solved exercises and answered open questions. Some of these questions were challenging and asked the groups to plan investigations to solve conceptual problems. Data analysed were constructed from video recording of the groups' activities and from an open test answered just before and after the course. Pos-test results show significant improvement compared to pre-test. It was also possible to observe development in students' comprehension of the theme.
