The current study addresses the limited research on knowledge acquisition in Project-Based Learning (PjBL) and assesses its development using a Multidimensional Curriculum Model (MdCM) among 563 elementary and secondary school students in Israel. The mixed-method approach involves a quantitative pre-post design, comparing intervention groups who…

Teachers adapt their instructional strategies over time based on a variety of contextual constraints. In response to these challenges, teachers often have to make changes to their PBL approaches. While the literature has documented generally positive results of initial PBL implementations, less is known about the degree to which teachers adapt…

Recent calls have been made to enhance and extend the statistical experiences of K-12 students. However, to ensure that such goals are met, teachers also need to develop deep conceptual understanding and pedagogical content knowledge that are essential to statistical thinking and reasoning. In this regard, over the past two decades, leading…

Well-designed problems are crucial for the success of problem-based learning (PBL). Previous discussions about designing problems for PBL have been rather general and inadequate in guiding educators and practitioners to design effective PBL problems. This paper introduces the 3C3R PBL problem design model as a conceptual framework for…

This may be due, in part, to the numerous challenges teachers experience when implementing PBL. In this paper, we describe specific hurdles that teachers are likely to…
