Presents a geometric discovery involving the use of a trapezoid as a base for a pyramid. Includes reproducible student worksheet to be used as a group-discovery exercise. (MKR)

Provides a cooperative-learning activity in which students calculate the horsepower of an individual by collecting and analyzing data. (ASK)

Describes how a researcher used student cooperative-learning teams to contribute test items. Discusses the questions generated by students and concludes that teachers have the flexibility to encourage students to generate and solve their own problems. Also concludes that students have the opportunity to be creative and formulate and pose questions…

Describes a mathematics review game that can be adapted to any content topic and which calls for the active participation of all students throughout the activity. (MKR)

Explores a quality control investigation with baseballs. Students were placed in groups of three to handle specific jobs: data recorder, measurement-instrument handler, and instrument reader. Includes assessment instruments and a list of suggested investigations. (MKR)

Discusses a course which combines Assessment, Investigation, and Mathematical Skills (A.I.M.S.) to originate, arouse, and sustain student interest in mathematics by changing to a more group-centered, democratic style of classroom management and by shifting toward more self-evaluation on the part of the students. (MKR)

Presented is a teacher's guide for a hands-on activity challenging students to develop problem-solving behaviors by exploring the construction of a right-cylinder of maximum volume from an m x n sheet of metal. Reproducible worksheets leading students through the activity are provided. (MDH)

Reviewed are the basic principles of cooperative learning including a rationale for its use and the formation of cooperative learning groups in the classroom. Examples of the application of this teaching method to mathematics teaching are discussed. (CW)

Presents and discusses assumptions for a general-mathematics problem-solving curriculum that incorporate the belief that all students can do algebra, geometry, and trigonometry, that mathematics must be presented in problem situations, and that students should work cooperatively. Worksheets provide exemplary problem-solving activities. (MDH)
