A. Collins’s scientific contributions

... The cognitive apprenticeship approach emphasizes teaching cognitive and metacognitive skills through modeling, scaffolding, and gradually transferring responsibility to learners. It situates learning in authentic tasks, enabling students to observe and practice expert problem-solving in real-world contexts, fostering a deeper understanding of complex skills (Collins, Brown, and Newman 1989). ...

Promoting professional vision of pre-service teachers: does the focus of analysis matter?

... Among the large variety of scaffolds reviewed in the literature, one frequently mentioned is modeling (van de Pol et al., 2010). In modeling, an expert demonstrates how to perform a complex task or skill thereby offering behavior for imitation (Collins et al., 1989;Hoogerheide et al., 2014;Tharp & Gallimore, 1988). Modeling is theoretically connected to social-cognitive learning (Bandura, 1986;Hodges et al., 2007) as well as example-based learning (Sweller et al., 2011). ...
