A Mathematics Teacher’s Learning in Design-based Research: The Brokering Supports through Different Collaborative Groups
... However, especially when making the 15-minute instructional videos, they easily put themselves in the field situation to notice students' actual reactions, but did not consider these reactions from an analytical perspective in regards to mathematical competence. To tackle this challenge, we arranged different types of collaborative groups to broker support for the designers, including peer teachers, MTE-Es, and MTE-Rs, and found that it helped with TPD (see Chang et al., 2020), especially in terms of connecting theories and practices. ...
Teacher professional development (TPD) is an important topic for school teaching and learning, but the challenging part is how to design quality and sustainable TPD that results in sound teachers’ learning. This research paper presents a cascade model of TPD used by the Just Do Math project and designed to nurture any number of teachers to teach mathematics in a more student-centered approach, rather than teaching mathematics in an inflexible way. The one-day workshop for cultivating leaders of mathematics-grounding activities in class (MGA-in-class), discussed in this article, is built on our previous TPD cascade model of scaling up the cultivation of designers, leaders, and teachers of mathematics-grounding activities for camps (MGA-for-camp). This paper focuses on presenting the process of developing and evaluating the one-day workshop for leaders of MGA-in-class. The development includes the processes of (1) how to transform activities designed for use in special camps to activities for use in regular classes, (2) how to cultivate the designers of MGA-in-class to be the facilitators in the one-day workshop for leaders of MGA-in-class, and (3) how to organize and evaluate the one-day workshop. Though the evidence shows that the one-day workshop has not recruited as many participants as previous TPD, the collected evidence provides useful information for future adjustment.
