Creating a Learning Space in Problem-based Learning

An important aspect of PBL problems is the affordances that they hold for engaging students in discussion of important content knowledge. In this paper, I argue that one can analyze a problem in terms of a deep problem space and a broader learning space to identify the conceptual ideas for potential engagement. The problem space refers to the specific ideas and concepts that are part of the goals of the problem at hand. The learning space includes those aspects of the problem space and also includes the broader space of related conceptual ideas such as the anatomy and physiology related to a particular disorder or the pathology and clinical medicine of other disorders that might be considered as part of a differential diagnosis. This idea is tested in an exploratory analysis of a PBL tutorial conducted by Howard Barrows. The results demonstrate that much of students’ talk is focused in these related conceptual spaces and a substantial amount of the overall learning space is engaged in the group discussion. These results have implications for understanding the affordances of problems and providing another lens on how learning unfolds in a PBL problem. It also provides another means for evaluation of learning and assessment of discursive productivity in PBL groups

On the Process and Outcomes of Inquiry Learning: Changing Approaches to Assessment [Organizer]

Inquiry learning is an educational approach that involves a process of exploration, asking questions and making discoveries in the search for new understandings. Researchers however are divided about the value of the approach. In the symposium, it is argued that one of the reasons for this controversy is the way that inquiry learning is assessed. Consequently, we aim to present papers which reflect on the challenge of assessing inquiry learning by describing the prevailing approaches to assessment and how technological and theoretical advancement is changing these approaches. The aim is not just to describe these approaches but reflect upon the opportunities that are created and difficulties that must be overcome as we pursue the goal of assessing the processes and outcomes of inquiry learning

Computer-Supported Collaborative Learning in STEM Domains: Towards a Meta-synthesis

Computer-Supported Collaborative Learning (CSCL) research has become pervasive in STEM education over the last several decades. The research presented here is part of an ongoing project to construct a meta-synthesis of CSCL findings in STEM domains. After a systematic search of the literature and article coding, cluster analysis results provided a frame for sampling from this literature in order to examine effects of CSCL. This preliminary meta-synthesis addresses the three key pillars of CSCL: the nature of collaboration, the technologies that are employed, and the pedagogical designs. CSCL tools and pedagogies typically improve collaborative learning processes along with achieving other learning and motivational goals

Modeling with a Conceptual representation: is it necessary? does it Work?

In response to recent educational imperatives in the United States, modeling and systems thinking have been identified as being critical for science learning. In this paper, we investigate models in the classroom from two important perspectives: (1) from the teacher perspective to understand how teachers perceive models and use models in the classroom and (2) from the students perspective to understand how student use model-based reasoning to represent their understanding in a classroom setting. Qualitative data collected from 19 teachers who attended a professional development workshop in the northeastern United States indicate that while teachers see the value in teaching to think with models (i.e., during inquiry practices), they tend to use models mostly as communication tools in the classroom. Quantitative data collected about the modeling practices of 42 middle school students who worked collaboratively in small groups (4–5 students) using a computer modeling program indicated that students tended to engage in more mechanistic and function-related thinking with time as they reasoned about a complex system. Furthermore, students had a typified trajectory of first adding and then next paring down ideas in their models. Implications for science education are discussed

Conceptual representations for transfer: A case study tracing back and looking forward

A primary goal of instruction is to prepare learners to transfer their knowledge and skills to new contexts, but how far this transfer goes is an open question.  In the research reported here, we seek to explain a case of transfer through examining the processes by which a conceptual representation used to reason about complex systems was transferred from one natural system (an aquarium ecosystem) to another natural system (human cells and body systems). In this case study, a teacher was motivated to generalize her understanding of the Structure, Behaviour, and Function (SBF) conceptual representation to modify her classroom instruction and teaching materials for another system. This case of transfer was unexpected and required that we trace back through the video and artefacts collected over several years of this teacher enacting a technology-rich classroom unit organized around this conceptual representation. We provide evidence of transfer using three data sources: (1) artefacts that the teacher created (2) in-depth semi-structured interview data with the teacher about how her understanding of the representation changed over time and (3) video data over multiple years, covering units on the aquatic ecosystem and the new system that the teacher applied the SBF representation to, the cell and body. Borrowing from interactive ethnography, we traced backward from where the teacher showed transfer to understand how she got there. The use of the actor-oriented transfer and preparation for future learning perspectives provided lenses for understanding transfer. Results of this study suggest that identifying similarities under the lens of SBF and using it as a conceptual tool are some primary factors that may have supported transfer
