How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
This paper describes how the notion of instructional situation can serve as a cornerstone for a subject specific theory of mathematics teaching. The high school geometry course in the U.S. (and some of its instructional situations — constructing a figure, exploring a figure, and doing proofs) is used to identify elements of a subject-specific langu...
This paper is part of a three-year inquiry that supports and investigates the work of groups of mathematics teacher educators using technological tools to design and implement multimedia practice-based teacher education curriculum materials. This paper describes the kinds of activities, interactions, and tools used by mathematics teacher educators...
We discuss affordances and liabilities of using a storyboard to depict a written case of a teacher’s dilemma that involves race, opportunity to learn, and student community. We rely on reflections by the teacher educator who authored the written case and later depicted it as a storyboard to use it with his preservice teachers (PSTs). The analysis i...
In this paper, we report on the potential of StoryCircles, a process of collaboratively representing a lesson using a storyboarding tool, for engaging teachers in substantive discussions about teaching mathematics. The analysis focuses on the interactions amongst a group of inservice teachers during which they wrestled with several dilemmas of prac...
Records of what takes place in mathematics classrooms are indispensable in mathematics teacher education and in research on mathematics teaching. We describe here the LessonSketch environment, an online platform for creating and analyzing representations of mathematics classrooms. We describe the authoring and analytic tools of LessonSketch with a...
“Implementing EMATHS (Embracing Mathematics, Assessment & Technology in High Schools) through LessonSketch StoryCircles” (also known as EMATHS) is a Mathematics and Science Partnership grant awarded in 2015 by Michigan's Department of Education in which Macomb County consultants use the LessonSketch platform to remotely engage groups of teachers in the process of creating representations of lessons from the EMATHS curriculum using a StoryCircles approach (developed by the GRIP at University of Michigan). Through the StoryCircles process, teachers share their experience and knowledge of practice to anticipate student responses to mathematical tasks and construct diverse ways of addressing student mathematical contributions.
To explore how web-based resources and tools, like the LessonSketch platform or the stand-alone Depict and Anotemos software, can be used to support the use of rich media in practice-based teacher education. Follow this link to modules created by the fellows: https://go.umd.edu/LRDMaterials Follow this link to meet the fellows: https://go.umd.edu/MeetFellows Follow this link to meet project staff: https://go.umd.edu/LRDProjectStaff 2020 update: Our Flash-based LessonSketch platform is fading. Still, the LessonSketch way of working will continue to be available, using a combination of shareware and our new software tools (Anotemos and Lesson Depict). These include facilities to annotate collaboratively videos and image sequences and facilities to author storyboards for scenario-based assessments and representations of teaching. And all our original content will be available to those who express interest in using it.
