Fostering Hooks and Shifts: Tutorial Tactics for Guided Mathematical Discovery

How do instructors guide students to discover mathematical content? Are current explanatory models of pedagogical practice suitable to capture pragmatic essentials of discovery-based instruction? We examined videographed data from the implementation of a natural user interface design for proportions, so as to determine one constructivist tutor’s methodology for fostering expert visualization of learning materials. Our analysis applied professional-perception cognitive–anthropological frameworks. However, several types of tutorial tactics we observed appeared to “fall between the cracks” of these frameworks, due to the discovery-based, physical, and semantically complex nature of our design. We tabulate and exemplify an expanded framework that accommodates the observed tactics. The study complements our earlier focus on students’ agency in discovery (in Abrahamson et al., Technol Knowl Learn 16(1):55–85, 2011) by offering an empirically validated resource for researchers, instructors, and professional developers interested in preparing future teaching for future technology.

Relational Equity and Mathematics Learning: Mutual Construction During Collaborative Problem Solving

We present an emerging interdisciplinary approach to the study of mathematics learning, which brings together strands from psychology and mathematics education. Our aim was to examine how students navigate the cognitive and social aspects of peer collaboration as they generate and adopt new strategies. We analyzed video data from a laboratory study involving pairs of elementary students working collaboratively to solve mathematical equivalence problems (e.g., 8 + 5 + 4 = 4 + ___). We adopted a qualitative micro-analytic approach that focused on multimodal action (i.e., verbal utterance, gesture, inscription production, body positioning, and eye gaze) to examine three cases. These cases illustrate the complex ways that students interacted in this particular context and, in some instances, attempted to teach one another. Our findings show how “relational equity” (Boaler, 2008) and mathematics knowledge were co-constructed differently in each case. We argue that a micro-analytic approach, complemented by a blending of theory from these two fields, reveals hidden aspects of the interaction that may help explain, for example, why some students generate or adopt correct strategies and others do not. As such, this interdisciplinary approach offers a rich account of the learning processes that occur in peer collaboration.
