This article presents a vector-analysis approach to the classical three-point problem in hydrogeology. Problem sets involving strike and dip, and ground water flow including computer programs (in BASIC) for their solution are given. (CW)

Presents a curriculum unit designed for average sixth-grade students intended to engage them in problem-solving experiences and to teach them problem-solving strategies. The curriculum consists of 20 sessions in which students engage in various activities using the following software packages: The Adventures of Jasper Woodbury, Rescue at Boone's…

Utilizes LOGO to teach the concept of inequalities by programing the turtle to take random walks in the coordinate plane restricted to predetermined regions defined by inequalities. The students task is to discover the inequalities that define the illegal areas into which the turtle must not move. Provides examples and corresponding computer…

Discussed is the place and teaching of trigonometry in a NCTM Standards-based mathematics curriculum. Presented is how these standards can be implemented in a technology-rich environment that encourages reasoning, communication, problem solving, and confidence building. Examples focus on functions, graphical sense, modeling, and identities. (KR)

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)

The quadratic function can be modeled in real life by a suspension bridge that supports a uniform weight. This activity uses concrete models and computer generated graphs to discover the mathematical model of the shape of the main cable of a suspension bridge. (MDH)

Discussion of technological innovations in education focuses on the potentials of the microcomputer as a classroom instructional method. Programing, computer literacy, software applications, and problem solving are suggested as ways to incorporate computers into the curriculum, and examples of applications of computers in elementary and secondary…

Discusses instructional uses for the "Carmen Sandiego" software series to encourage interest in geography. Suggests "Carmen" be incorporated into the curriculum by teacher-directed grouping that adds teacher instruction into cooperative and competitive arenas, curriculum integration linking diverse specialties, and isolated…

Identifies areas of knowledge that differ between successful and at-risk students: sense of self-as-learner, level of understanding of problems in subjects, and ability to interact in relationships. Suggests a hands-on project to develop problem-solving abilities and self-confidence. Discusses objectives for a restructured curriculum. (DK)

This study of third graders examined whether qualitatively distinct cooperative computer environments (using LOGO and curriculum-based instruction in writing) engender social experiences that enhance motivation and self-concepts as learners; and the extent to which differences in motivation and self-perception accounted for differences in…

Discussion of graphing software for educational purposes focuses on a study in which three versions of an original computer graphing program were used by inner-city high school students to solve scientific data analysis problems. Variations in degrees of flexibility and feedback in the software are explored. (Contains 37 references.) (LRW)

Relates findings of an empirical study of student use of an interactive videodisc to theories of learning and to other research findings. A study of 12- and 13-year-old students in England is described that examined problem-solving strategies, learning styles, conceptual understanding, group discussion, and the teacher's role. (Contains 17…

Uses work on children's counting schemes and a radical constructivist orientation to describe the development of computer microworlds for the teaching of rational numbers. Suggests that the design of complex software systems needs a strong theoretical background to provide direction for the design. Suggests that computer environments are the…
