The adoption of Emergency Remote Teaching (ERT) during the COVID-19 Pandemic brought a shift in how lecturers teach in higher education, posing a threat to the usual development of competencies in students. This study aimed to uncover the knowledge and skills backlogs experienced by pre-service teachers. The study is framed within various concepts that characterize an ideal science teacher. Using a qualitative case-study design, data were collected through interviews with nine pre-service teachers who were subjected to the ERT. Transcripts of the interviews were analyzed thematically using the established framework as a lens. The findings indicate that while the science pre-service teachers acquired some technological knowledge, there was a concurrent loss of sufficient content knowledge, a crucial prerequisite for the development of Pedagogical Content Knowledge (PCK). Additionally, the pre-service science teachers highlighted alack of knowledge in practical work and the specific pedagogies essential for teaching science. The implications of these findings are discussed in the context of moving forward
