Six students (ages 12-14) with learning disabilities received either cognitive or metacognitive strategy instruction for mathematical problem solving, followed by instruction in the complementary component. Results indicated that cognitive and metacognitive strategies were more effective than either cognitive or metacognitive strategy instruction…

Presented is an activity in which probability and percents are taught using a basketball computer simulation. Computer programs that replicate the free-throw accuracy of college and professional stars and allow students to compete with those stars are included. (KR)

Discussed is the research project that used small-group problem solving as a primary instructional strategy of second grade mathematics for an entire year. The mutual construction of classroom norms for cooperative learning style is illustrated and examples of resulting learning opportunities are given. (MDH)

A simple matrix that can be used as a tool for analyzing environmental actions is presented. By using this matrix and focusing on examples of efforts to resolve environmental issues, students can build a mental model of how environmental problems are solved. (KR)

Describes three components of a seminar in mathematical problem solving for preservice mathematics teachers: (1) a cognitive component that accents particular phases of problem solving; (2) an affective component that allows for observation of skillful problem solvers; and (3) an investigative component that provides for independent study and…

Describes the process of problem identification, data collection, and generalization in a mathematical experiment to find the speed at which a bug travels at the end of a fan blade. Presents the learning outcomes of the experiment and possible implications of using this teaching method. (MDH)

An activity in which students research the effectiveness of recycling is presented. Students compare the types and amount of litter both before and after recycling is implemented. Directions for the activity and a sample data sheet are included. (KR)

Demonstrates ways that a classroom teacher can get a distorted picture of English-as-a-Second-Language (ESL) students and their resources and how viewing literacy in a social context illustrates the way relationships are negotiated. Suggestions are made for teachers to create ESL classrooms where the role of literacy in students' lives can be…

Presented are classroom activities in which students explore the potential use of magnetic levitation for transportation purposes. The advantages of using a MagLev transportation system instead of conventional trains are discussed. Directions for designing and building a MagLev track and circuit are provided. (KR)

Examines didactic interventions and claims their impact on pupil behavior aids the study of cognitive processes. Studies problem solving in teaching mathematics. Examines the functions of tutorial interventions in surface features and instability of representation. Finds tutorial interventions demonstrate a substantial increase in performance…

A mathematics staff development program engaged kindergarten through twelfth grade Georgia teachers in a constructivist approach to learning for use in the classroom. The Problem-Solving and Thinking Project emphasized that teacher and student learning is not done passively and that teachers must be taught as it is hoped they will teach. (SM)

Describes a report writing unit that is part of a three-year language/communication course for second language engineering students at the University of the Witwatersrand in South Africa. States that the tasks motivated the students to develop their report writing and oral skills. (RS)

The relationship between mental models used in problem solving and strategies children use when problem solving with manipulative materials are discussed. Teaching strategies for bridging the gap between the two are suggested. (CW)

Four activities which illustrate the use of manipulative materials and computers in problem solving at the elementary level are presented. Each activity discusses large group activity and a computer activity. (CW)

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) is reported. MANOVA results indicate significant difference between expert and novice students solving the five stoichiometric chemistry problems using…
