A course on Basic Acoustics has been implemented as an Internet site with multimedia resources such as Flash animations, video clips, etc. Multimedia resources are particularly suitable for acoustics, due to the special role played by sound. The constructivistic model of learning within the EHEA framework was taken as the most suitable approach. The students’ overall evaluation has been positive, especially as regards the embedded multimedia resources. Furthermore, many comments taken from their evaluations and assignments have helped to correct deficiencies and to improve the course.
