Publication | To contribute to understanding how teachers can develop geometrical understanding, we report on the discursive development of teachers’ geometrical reasoning through instrument appropriation while collaborating in an online dynamic geometry…
Publication | Rich tasks can be vehicles for productive mathematical discussions. How to support such discourse in collaborative digital environments is the focus of our theorization and empirical examination of task design that emerges from a larger research…
Publication | We report on a case study that seeks to understand how teachers’ pedagogical interventions influence students’ instrumentation and mathematical reasoning in a collaborative, dynamic geometry environment. A high school teacher engaged a class of…
Publication | Students travel through a series of lessons as they analyze data and unpack the meaning of measures of center.
Publication | On July 15-17, 2012 the United States National Commission on Mathematics Instruction and Seoul National University held a joint Korea-U.S. workshop on Mathematics Teaching and Curriculum. The workshop was organized to address questions and…
Tool | No one curriculum can meet the needs of all students and teachers. This video describes why a teacher might want to modify a curriculum and how he or she would go about it.
Tool | "Content coherence"--ideas presented in a connected, sequential way--plays a big role in effective science instruction. Watch this video to find out how it works and how students benefit!
Presentation | An effective curriculum helps you support students' science learning, understanding, and achievement. But what does "effective" mean? This video gives you the inside scoop on what makes a curriculum effective and flags some common pitfalls to…
Publication | To examine the value of the electronic teacher guide (eTG) as a curriculum planning and teaching tool,
it was important to study it in the contexts of teachers’ actual planning, teaching, and reflecting.
This paper described two descriptive…
Publication | This project uses plots from books by Roald Dahl, Judy Blume, and others to teach STEM concepts.
Publication | This paper explores the potential of integrating critical and place-based perspectives supported by mobile, digital technologies in secondary mathematics. The paper describes two curricular modules: Local Lotto, a mathematical…
