Open peer commentary on the article “Examining the Role of Re-Presentation in Mathematical Problem Solving: An Application of Ernst von Glasersfeld’s Conceptual Analysis” by Victor V. Cifarelli & Volkan Sevim. Upshot: Cifarelli and Sevim discuss the development of individual students’ abstract conceptual structures while problem solving, using constructs for analysis that are consistent with von Glasersfeld’s radical constructivism: re-presentation and reflective abstraction. This commentary discusses the on-going contributions of reflective abstraction to individual and collective learning.

Purpose: In the educational field a lack of focus on the process of arriving at a level of profound understanding of a phenomenon can be observed. While classical approaches in education focus on “downloading,” repeating, or sometimes optimizing relatively stable chunks of knowledge (both facts and procedural knowledge), this paper proposes to shift the center of attention towards a more dynamic and constructivist perspective: learning as a process of individual and collective knowledge creation and knowledge construction. The goal of this process is to profoundly understand a phenomenon in its multi-dimensionality and complexity and to reflect on the processes that have lead to this understanding. The issue we want to tackle in this paper is how this profound understanding can be brought about in a technology-enhanced learning environment. Method: Part 1 of this paper explores strategies of technology-enhanced knowledge sharing/creation in the field of higher education. Part 2 presents a successful blended learning scenario that illustrates the implementation of these learning strategies in a concrete course design. In this case study students are involved in active theory construction processes by conducting virtual experiments with a virtual organism. Part 3 elaborates on the epistemological implications of this case study. Findings: A constructivist framework for modes of knowing and modes of coming to know is developed. It is shown that – in order to reach a profound understanding of a phenomenon – it is essential to take into account the multi-facetted character of knowledge and to use the strategy of double-loop learning. Conclusion: This leads to an understanding of learning/teaching as a process of socio-epistemological engineering. Furthermore, the role of the teacher changes in such a constructivist setting of learning/teaching: Their primary task is to provide a “pedagogically (and technologically) augmented environment.” They are responsible for creating an atmosphere of collective knowledge construction and reflection. Beyond the role of a coach and moderator the teacher has to act as a facilitator or “enabler” for the (individual and collective) processes of double-loop learning.

Context: The main aim in organizing academic conferences is to share and develop knowledge in the focus area of the conference. Most conferences, however, are organized in a traditional way: two or three keynote presentations and a series of parallel sessions where participants present their research work, mainly using PowerPoint or Prezi presentations, with little interaction between participants. Problem: Each year, a huge number of academic events and conferences is organized. Yet their typical design is mainly based on a passive way of sharing knowledge. No models for an adequate conference design and an appropriate learning environment are available. The overall conference design, however, is a crucial aspect in the learning of the participants and deserves special attention from conference organizers. Method: I have organized around 15 carefully designed conferences (and attended many more. These have been the steps of an ongoing exploration to learn from each of these events and develop a deeper understanding of adequate conference designs and stimulating learning environments. This paper reports on my understandings of the organization of a selection of these conferences (in architecture, arts and design) and on the way knowledge sharing and knowledge development was stimulated at these events. These conferences included less traditional conference designs, collective learning and explicit sharing of understanding between participants. Results: Collaboration in small groups and joint plenary discussions, plenty of time for interaction and generous feedback to presenters turn out to be very valuable for consolidating knowledge and envisioning future developments in a discipline. Also, it is our experience that the presence of design objects as a trigger and catalyst for discussing and learning makes a huge difference in sharing and developing new knowledge. This paper aims to highlight the importance and raise awareness of different methods of stimulating the construction of knowledge by conference participants. I hope it will inspire future conference organizers and help them to induce more deliberate knowledge construction amongst participants. Implications: Insights from this paper are relevant for all conference organizers, especially those in the domain of architecture, arts and design. It has become clear that it is beneficial to have exhibit-type presentations as well as moments of collective learning. Organizers are recommended to adopt an explicit conference design. Constructivist content: Following a constructivist approach to learning environments, this paper stresses the importance of scheduling moments of active and collective learning and knowledge construction explicitly during academic conferences.

Key words: Conference design, collective learning, collective tutoring, knowledge construction.
