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)

Discusses declining school computer use and increasing societal computer misuse. Resistance to school computer use results from the quality of experiences educators and students have with them. Learning ethical computer usage is important for students and society. Eight steps for creating a curriculum on ethical computer use are provided. (SM)

Describes four areas of educational change: (1) the curriculum, (2) the role of the teachers, (3) the school structure, and (4) student learning. The impact of intensive computer use on each of these areas is examined using observations from a "technology-enriched" school project that is currently underway (1989-92) in the Netherlands.…

The introduction of informatics into the national school curriculum in Japan requires changes to educational policy, curricula, methods, facilities, etc. Although the basic functions of the school--i.e., to transmit the culture and to cultivate competencies that will allow a future society to develop--remain unchanged, new technologies change the…

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)

Illustrates where several unexpected patterns of antiderivatives can be realized during calculus instruction via the application of integration by parts to the exploration of particular members of families of functions. (JJK)

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…

Presents eight points to emphasize when teaching the concept of place value. Contends that converting numbers from one base to another helps students understand the concept of place value and the importance of context in establishing meaning. Provides a BASIC computer program to make conversions. (MDH)

Describes an interactive video system, VISTRAIN (Video-Based Integrated System for Training Applications), which was developed by the National Computing Centre in the United Kingdom for the Scottish Police College to help train police supervisory officers in crowd control. Group training is discussed, and management training applications are…

Proposes a taxonomy to aid decision makers in selecting computer software consistent with their educational values regarding the nature of instruction and the use of information technology, based on beliefs about human development and learning. Characteristics of instruction, properties of software, and the congruence between them are discussed.…

Demonstrates how an information systems plan can be successfully developed and implemented within an academic setting. Six guidelines for information systems planning are provided; problems are identified and recommendations to address the problems are suggested; and information systems objectives are discussed, including business communications,…

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…
