One mathematics lesson was planned by two Grade 2 teachers together. Their separate teaching of it was videotaped, and each teacher was interviewed before and after her lesson. The "same" lesson resulted in different sets of worthwhile learning outcomes. In this research report, the notion of situated cognition is used as a tool for analysis of…

This study examines the learning of five pre-service teachers investigating a question stemming from their mathematics teaching as part of a final course project in their elementary teacher education program. Analysis of video recordings of group meetings and interviews indicate that as pre-service teachers completed their projects they developed…

We examine aspects of flexible mathematical thinking in middle school students and its contribution to the growth of their mathematical understanding. We inductively analyzed data collected from video-episodes of an interactive, problem-solving based after-school mathematics class. Flexibility is essential in such classrooms since students must…

This monograph is a guide to effective presentation of report data and information from institutional research. The work focuses on several types of presentation: the written report (alternative ways for presenting information, appearance, and the audience); graphic displays or charts (to present words or data in an organized or symbolic fashion;…

The purpose of this study was to determine whether asynchrony between audio and visual presentation in distance education classes had an impact on student perceptions of distance learning and student achievement. Six distance education courses, all in different disciplines, were taught from six different locations to a minimum of one satellite…

Gives the guidelines for a unit of study based on creative activities. Defines procedures, rules of the game, and basic information. The exercises provide instructions and suggestions to stimulate the learners to gradually build a fictional world as a backdrop for the interaction of characters emerging from group work and discussion.

Reports on an experiment where 64 elementary school students participated in reading, clapping, and vocalizing rhythms notated in color. Results after a 23-week treatment period revealed that the experimental group scored slightly higher reading both colored and uncolored notation than a control group. (MJP)

Reviews a teaching strategy built on the body of research revealing crossword puzzles as effective means of introducing fundamental concepts and vocabulary. Discusses methods for constructing the puzzle. Student responses suggest that the puzzle was useful as a tool for both learning and review. (MJP)
