Abstract(s)School textbooks are an outstanding resource in school physics. The illustrations included in the textbooks may play an important role in the learning process as they can facilitate the understanding of the scientific content. Acoustics is both a part of the 8th grade physical science syllabus and a physics topic that includes abstract concepts, such as the concept of wave. Besides, students hold several alternative conceptions on sound. Therefore, textbooks’ illustrations should be carefully chosen in order to facilitate students’ learning and to prevent their alternative conceptions from being reinforced and/or induced by them. Thus, this study aims at analysing the illustrations included in Portuguese 8th grade school physics textbooks in order to find out whether or not they may promote the reconstruction of students’ alternative conceptions on “Sound and Hearing”. The results of the study show that often textbooks’ illustrations do not facilitate learning. In fact, some illustrations were found to be incomplete or even incorrect, others compare to alternative conceptions held by students and others include analogies that may lead to alternative conceptions. Thus, science teacher education needs to prepare teachers to look critically at school textbooks so that they become aware of the powers and limitations of textbook’s illustrations and find ways of overcoming their inconvenience.
