Learning To Teach Mathematics And To Analyze Teaching Effectiveness: Evidence From A Video- And Practice-Based Pre-Service Course, Rossella Santagata, Cathery Yeh
Education Faculty Articles and Research
Although emerging consensus exists that practice-based approaches to teacher preparation assist in closing the distance between university coursework and fieldwork experiences and in assuring that future teachers learn to implement innovative research-based instructional strategies, little empirical research has investigated teacher learning from this approach. This study examines the impact of a video- and practice-based course on prospective teachers’ mathematics classroom practices and analysis of their own teaching. Two groups of elementary prospective teachers participated in the study—one attended the course and one did not. Findings reveal that the course assisted participants in making student thinking visible and in pursuing it …

I Have A Solution To Share: Learning Through Equitable Participation In A Mathematics Classroom, Mary Q. Foote, Rachel Lambert
Education Faculty Articles and Research
Student participation is an issue of equity. Without participation there can be no learning. This study focuses on the participation (and therefore learning) of struggling students (those with individual education plans [IEPs]) during the implementation of a relational thinking routine in a third-grade inclusion classroom. Students with IEPs often initially used direct modeling with linking cubes as a resource for presenting their thinking. In this way, they were able to demonstrate their ability to think relationally. As the year progressed, these students, who had earlier been reluctant to share and had done so only by using several of the resources …

The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller
The Pet Food Recall Puzzle: Who, What, Why, And How Much, Roxanne Greitz Miller
Education Faculty Articles and Research
Last spring, North America was gripped in the largest pet food recall in history. News outlets reported tens of thousands of dogs and cats becoming ill, and many dying, as a result of ingesting contaminated pet food. Several pet owners have filed lawsuits against the manufacturers and distributors of the pet food products. I think this is an excellent real-life science story to use with students to show science investigation in action, and to discuss the intersections between the role of regulatory agencies and the public.
In order to understand the case, you first have to know the facts. We'll …
