The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

The focus of this article is on how computer graphics can be integrated throughout the engineering graphics curriculum to increase visual perceptual skills. Visual perception is defined, the need to develop it is described, and methods which engineering graphics educators can use to develop it are outlined. (KR)

A paradigm that suggests the critical factor of quality rather than quantity of knowledge is proposed. The potential for retention and transfer in using a design and technology approach is discussed. Activities that generate relevant data for students are provided. (KR)

This review features new examples of using the computer relative to college-level mathematics to enhance pedagogy, solve problems, and model real-life situations. Included is a LOGO program that can be used to create and to stimulate subsequent investigations of spirolaterals, those figures generated by repeatedly drawing basic loops. (JJK)

Describes a new strategy for informing and involving people in environmental issues. Presents stories of successful efforts by ordinary people to effect environmental change. Suggests that these stories can provide the help people need to build more adequate models about environmental problems and about their roles in addressing them. (27…

Researchers investigated the effects of metacognitive mathematics instruction on low-ability, mainly Hispanic, sixth graders. Lack of linguistic, strategic, and procedural knowledge was the major source of errors in solving problems. Pre- and posttesting indicated students receiving metacognitive instruction progressed as problem solvers and…

Presents contributions by six mathematics teachers responding to the question: "How has the history of mathematics mattered to me in my mathematics teaching?" Answers touch the topics of how and why, how benefits are accrued, use of original texts, integration into core curriculum courses, and pitfalls of history. (MDH)

Presents a student project that requires students to create a puzzle involving some form of manipulative and present it to the class with an advertisement. Uses writing to have students report on their progress. (MDH)

Presents a simple mathematical model in which resultant speed is the sum or difference between wind speed and runner speed and a more complex model that assumes that only a proportion of the wind's speed affects one's running speed to describe the time difference between running with and without wind. (MDH)

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…

Assessed impact of school-based social competence training on skills, social adjustment, and self-reported substance use of 282 sixth and seventh graders. Found positive training effects on subjects' skills in handling interpersonal problems and coping with anxiety. Teacher ratings revealed improvements in subjects' constructive conflict…

The Purdue Three-Stage Model was applied in a seminar program for intellectually talented middle school students, with the goals of achieving maximum competence; stimulating curiosity and interest; and developing creative and critical thinking, problem-solving ability, independence, and self-direction. The article offers information on student…

A problem-based predoctoral dental implantology course at the University of Texas had small tutorial groups solve specific patient problems through discussion, individual research, clinical experience, and subsequent sharing of knowledge. Student reactions were enthusiastically positive and their performance exceeded faculty expectations.…

Students who learn more geography have a dual payoff: intellectual challenge through the introduction of new, stimulating information about people, places, and regions; and exposure to career possibilities that did not exist even five years ago. The 18 national geography standards stress a spatial world view, places and regions, physical and human…
