A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

Four techniques used to incorporate writing and active learning into mathematics classrooms are described. They include summary sheets, short focused writing, medium length writing, and student presentations. Examples of how each technique can be used are included. (KR)

The perspective of biotechnology and its development in the K-12 technology education curriculum are described. The content curriculum development and implications for activities are discussed. The difference between a curriculum focused on the activities of industry compared to one that addresses technology as it pervades all human endeavors is…

An interdisciplinary robotics project undertaken by students is described. The students acted as designers, innovators, and the engineers in designing a dancing robot. The origin of the problem, designing of the mechanical frame, pneumatics, digitized sound, and problems with the design are discussed. (KR)

This article describes a calculus lesson that illustrates the nature of cycles in simple systems of nonlinear differential equations through the use of the Lotka-Volterra predator-prey model as incorporated in the computer software package, Phaser (version 1.0). (JJK)

Discusses examinations as the major determinant of student behavior and suggests that no improvement in the effectiveness of biochemistry courses will occur until examinations are so integrated into the educational process that they reinforce educational objectives. Includes discussions on self-education, cooperation between students, and problem…

Develops the idea of fractals through a laboratory activity that calculates the fractal dimension of ordinary white bread. Extends use of the fractal dimension to compare other complex structures as other breads and sponges. (MDH)

Small group work has grown in use throughout the 1980s. Reported are six issues that were raised concerning small groups resulting from a series of workshops for university students in which the students worked on problems in groups, jointly planned tasks, and critiquing their use during their practice experience. (MDH)

Presents a series of hands-on activities for grades K-2, 3-4, 5-6, and 6-8 using the common theme of kites to develop number sense in basic operations and fractions. Teachers' guides and worksheets are provided. (MDH)

Presents a study conducted to investigate the subjective experiences of a teacher making the transition from a traditional textbook, content-dispensing approach to a problem-solving approach to teaching science. Although outward changes in teaching materials and strategy are evidenced, the teacher shows little change in beliefs about the teacher's…

Presents teaching methods to rectify the tendency of students and even teachers to divide the smaller number into the larger in problem situations requiring division, while recognizing the impossibility of the answer in the situation. (MDH)

Presents activities that relate the Olympic Games to measurement. Includes descriptions of and worksheets for 5 activities involving estimation, nonstandard units of measure, linear measure, and time measurement for grade levels K-2, 2-4, and 5-8. (MDH)

Presents activities that integrate story telling, history, and problem solving as a stimulus for discussion and creativity in the elementary mathematics classroom, and a way to relieve children's anxiety in an escalating curriculum. (MDH)
