“…Regarding the behavior of sound waves, the students demonstrated a good understanding of reflection, refraction, and absorption, including correctly identifying the most appropriate materials for acoustic insulation, contrary to the results obtained by Bolat and Sözen [40]. Nonetheless, about the Doppler Effect, the PSTs' answers revealed incorrect links that were made between some of the concepts, such as in the study developed by Mosabala [36].…”

“…This research intends to contribute to this gap, studying the effects of STEM activities, according to the IBL methodology, in the CK and PCK of primary PSTs about sound concepts. The sound topic was chosen because it is present in the curriculum guidelines from the first levels of schooling [31], involving fundamental concepts for the learning of complex physics concepts [32], and numerous studies reveal the persistence of alternative conceptions in students [33][34][35][36][37][38] and future teachers [32,39,40].…”

STEM (Science-Technology-Engineering-Mathematics) education has received great attention in recent years not only for promoting interest and learning in these areas but also for encouraging children and young people to pursue careers in them. This research explored the effects of a STEM program in developing the primary pre-service teachers’ Content Knowledge (CK) and Pedagogical Content Knowledge (PCK) about sound. A qualitative and interpretative study analyzed the impact of a STEM program on the CK and PCK of 18 pre-service primary teachers that were attending a master’s degree program in a Portuguese higher education institution. The data was collected from their lesson plans, field notes, a focus group interview, and participants assignments throughout the STEM activities carried out. Findings revealed several scientific misconceptions and weaknesses in the participants’ PCK. Nevertheless, there was a clear positive impact on pre-service teachers’ CK and PCK, specifically regarding the principles underlying STEM integration that was proposed in the conceptual framework.

“…The Doppler effect is an apparent shift in the observed frequency of a sound wave due to the relative motion of the source and of the observer. What really increases is the sound intensity, which often leads to these inconsistencies, as mentioned by Mosabala (2014), who obtained similar results. Neuhoff and McBeath (1997) called it the "Doppler illusion" and explained that the main cause of these misunderstandings about the Doppler effect is related to the often-confused distinction between frequency (that is actually decreasing as the source approaches the observer) and perceptual pitch.…”

Background: STEM education has been in focus in recent years given its innumerable potential for developing diverse skills and encouraging the pursuit of careers in the STEM areas. In this way, since initial training, it is crucial to create conditions for preservice teachers (PSTs) in STEM experiences that encourage the development of their subject matter knowledge (SMK). Objectives: This study aims to examine the effects of STEM activities centred on inquiry-based learning on PSTs' SMK about sound phenomena and concepts. Design: This is a qualitative and interpretative study. Setting and Participants: The participants are nine preservice teachers studying in a Portuguese higher education institution. Data collection and analysis: Two data collection methods were used: (i) students' productions developed through six STEM activities that included sound-related concepts, such as sound vibration, wave, transmission, velocity, and loudness and (ii) field notes. To analyse the data, we used an inductive strategy of content analysis. Results: Results revealed that the preservice teachers initially misconceived sound and had their subject matter knowledge improved after the activities. Conclusions: STEM approach favoured an active involvement of PSTs in their learning, connecting contents to real-life situations.
