Describes how 4th grade students thought like mathematicians and illustrates their thinking through classroom vignettes. (KHR)

Explains the importance of peer assessment in professional life and describes a course using peer review processes to teach modeling in natural resource management. Uses a typical scientific research protocol and assigns students to review peer proposals considering their expertise and area of interest. Presents guidelines for proposal review,…

Explains that in dynamics, the process of finding the direction of force acting on a moving object can be structured as a syllogism. Uses the syllogistic form of a scientific explanation task to help middle school students change their prior conceptions about force and motion. Reports four factors preventing students' use of deductive reasoning.…

A control group of 13 extension agents received traditional inservice training; 13 others used an interactive website. No posttest differences were found based on training method or level of computer anxiety at the knowledge level of Bloom's taxonomy. At the application level, the traditional group had higher scores. (Contains 27 references.) (SK)

Examined geographical representations among children and young adults. Found that a distinct home region was apparent at age 9. At age 11, children divided North America into regions the same as university students. Children used new location information to update location estimates. Children preserved ordinal structure of initial location…

Describes how to evaluate trade books (i.e., books other than textbooks) that are oriented towards teaching mathematics. (Contains 22 references.) (Author)

Discusses examples of the detailed explanations that students offered in response to a written, open-ended geometry task, especially the ways in which students communicated their knowledge. Illustrates how different students may select different methods of communication such as using text, diagrams, or mathematical symbols to display their…

Describes how students can be guided to find an explicit rule for a pattern from a recursive rule. (YDS)

Presents action research in the classroom that involves a semantic feature analysis task to help students develop reasoning skills. (YDS)

Illustrates the varied mathematical reasoning involved when a geometric construction problem is solved with three different manipulative tools. (Author/NB)

Presents an activity using similar rectangles to help children conceptualize ratio relationships in several different ways. Develops proportional reasoning without introducing the process of cross- multiplication. (YDS)

Develops a week-long, problem-based mathematics curriculum focusing on proportions and explains instructional and assessment strategies. (YDS)

Describes an activity in which students demonstrate through a variety of creative mathematical analogies just how big Bill Gates's fortune is. (YDS)

Helps students develop new insights into mathematical relationships through alternative representations. Examines patterns, symbolic, and functions approaches. (Contains 11 references.) (YDS)

Describes a study on how effective teachers use manipulatives successfully. Presents factors to recognize when manipulative-based lessons are identified and discusses ways in which the use of manipulatives can go astray. (YDS)
