Assessed the achievement in addition, subtraction, multiplication, and division of 93 fourth graders before and after they received either computer or traditional classroom drill-and-practice instruction. Students who received computer instruction showed greater increases in achievement scores in subtraction and multiplication than did students…

Asserts that college students lack understanding of the concept of function. Based on an epistemological theory, offers an instructional treatment using computers that presents a process concept of function and results in substantial improvements in student understanding for many students.

One Massachusetts elementary school, desegregated and rebuilt with a complete system of state-of-the-art technology and infrastructure, has shown how technology can influence school restructuring and student achievement. School's technology is integrated into the whole curriculum. Garfield School's experience shows that computers can benefit both…

Observation of English-as-a-Second-Language students' small-group writing activities involving a word processor found that the word processor was a valuable tool in promoting writing abilities and providing excellent interactional activity. (four references) (Author/CB)

Describes study of university students that investigated the effects of two direct instruction techniques in a computer-based algebra lesson: the cognitive routine (CR) and the Corrective Feedback Paradigm (CFP). Research design is explained, results are analyzed, and further research is suggested. (nine references) (LRW)

Discussion of the use of interactive videodisc in teacher education focuses on a study of elementary education teacher students that investigated the effects of interactive video on learning concepts of cooperative learning. Treatment of experimental and control groups is described, and a model for using videodisc in teacher education is…

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)
