This article is aimed at teachers already experienced with activities involving small, student-collected data sets and who are now ready to begin working with large, online data sets collected by scientists and engineers. The authors discuss challenges, instructional strategies, and sources of appropriate lesson plans. With guidance, plus online…

The classroom with its teaching-learning dynamics creates a kind of "embryonic society" in which the micro-policies of collective social knowledge construction and meaning can be re-constructed; therefore, it can be considered as a kind of "mirror" of political culture. Thus, comparative lesson research, which requires in-depth…

In winter 2014, I came upon an opportunity to conduct a case study on a team of middle school math teachers who initiated a study group to examine how a set of learning progressions could help them with their planning, instruction, and assessment. Learning progressions are research-based hypotheses about how students develop more sophisticated…

Presents activities using the theme of collecting and interpreting data from the students' own classroom. Stresses communication among students and between students and the teacher. Includes reproducible student worksheets. (MKR)

Presents a lesson plan detailing an interdisciplinary mathematics/science activity in which students take a home survey of light bulbs and then design an energy-saving lighting system for a home. Contains reproducible student worksheets. (MKR)

Focuses on connections between mathematics and environmental concerns. Activities were designed to make students aware of, and increase their knowledge of, the various materials people ordinarily use and discard and ways to use materials more conservatively. Each activity includes data gathering, graphing, and interpreting data. Activity sheets…
