Reports an example of one lesson from a sequence of lessons on fractions from a sixth grade class in which the teacher revises her plans after observing students' small-group work and interactions. The lesson illustrated the teacher's knowledge of mathematics, how students think, and how to observe that thinking. (MDH)

Overcoming obstacles to teacher research about their own educational practices requires the formation of intellectual communities of teacher-researchers or networks of teachers. An analytic framework is presented for interpreting and evaluating the work of such groups according to how they use time, talk, construct texts, and interpret teaching…

Describes the use of DIALOG and Classmate by students at McDowell High School (Texas). Requirements for accessing DIALOG are explained; methods of teaching using DIALOG are described, including planning search strategy and the use of small groups; and problems are reviewed, including supervision time, cost, and limited accessibility. (three…

Describes Thinking Mathematics, a research-based approach to teaching mathematics. Value is placed on thinking and communicating mathematically and using what is known to find the unknown. The program requires teachers to rethink their beliefs and assumptions about teaching and learning mathematics. Examples of program implementation are given.…

The use of strategies is an important part of mathematical thinking. Presented are several games that help develop the reasoning strategies of hypothesis making and testing, proving and disproving, looking for patterns, and simplifying a difficult task. (MDH)

Provides excerpts from videotaped dialogue between two third grade students and their interactions with their teacher while solving a counting problem to describe student thinking and communication during the task. Discusses the teachers' role in the dialogue and implications for classroom practice. (MDH)

Presents integrated activities for mathematics and biology appropriate for various levels from grades five through eight. Explores interesting aspects of human fingernails and hair growth and their mathematical relationship to time. Provides suggestions to integrate the activities with technology. (MDH)

Forms and characteristics of small group physics instruction in the Russian university are examined and in some cases, compared to those used in Britain. Topics discussed include the lecture method, classroom communication during lectures, postlecture discussion, specialized small-audience lectures, problem solving, individual research projects,…

Maintains that, although courts have ruled that poor people accused of crimes must be provided legal services, most court cases involve civil law. Presents a secondary school lesson in which students review 11 mock civil court cases and decide whether or not free legal counsel should be provided. (CFR)

Argues that critical thinking is best learned where fellow students respond and react as well as replicate and evaluate. Suggests methods and techniques for doing critical thinking. Discusses thesis formulation, concept application, judgments and conclusions, cause and effect relationships, criteria identification, structure and function,…

Presents a series of 13 activities to explore the mathematics of baseball. Activities examine the numerical measures of player statistics and team standings and the geometry of baseball. Discusses the use of computer spreadsheets and LOGO computer simulations to study the concepts embodied in the activities. (MDH)

This article discusses a widespread failure of schools to match reading instruction to children's needs, identifying large class sizes, dependence on basal reader programs and questionable testing practices as contributing factors. Basal materials are seen as contributing to standardized curricula and impeding efforts to shift teacher behavior…

Reviews recent literature on urban politics and urban policy. Focuses on issues faced by cities of the 1990s: city planning, growth, politics, problems of housing, homelessness, cost of government, racial, and ethnic conflicts. Suggests that field trips and computer simulations can be used in college courses in urban studies. (CH)

Describes three activities to teach mathematical concepts involving probabilities related to outcomes using "Sicherman" and other dice; geometric representations of algebraic identities; and the volume of a cone. (MDH)

Presents an exciting way to acquaint students with current methods to clean up oil spills. Students also have the freedom to create new clean-up methods as they think through the problem and experiment to find effective solutions. (PR)
