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)

Some important considerations for potential courseware authors to think about before they enter the authoring process are discussed. A description of the hardware requirements, an evaluation of 11 authoring tools based on quality and cost, and the conclusions are provided. (KR)

Selective illustrative examples of students' learning difficulties and misconceptions in first-year general and organic chemistry are presented in the students' terms, followed by strategies the author uses to overcome the difficulties. Suggests that student misconceptions in first-year chemistry are not interrelated logically and are not prone to…

Provides examples of how concept mapping can be used to help overcome misconceptions in college chemistry. (PR)

Described is a professional development program at Heriot-Watt University in Scotland. Discussed are the teaching of the relationship of civil engineering to society and ethics, issues about the style of this type of course, and summative evaluation. Recommendations are provided. (CW)

Discussed are the objectives of higher technical education, and computer hardware and software requirements for engineering education. One approach to meeting these objectives is described using a Belgian university as an example. (CW)

The improvement in student attitudes as the result of the use of videomicroscopy in the science classroom at the elementary, secondary, and college levels is discussed. The results of published research studies are reviewed. (CW)

Examined is the predictive value of the cognitive variables of developmental level, mental capacity, cognitive style, short-term storage space, and numerical inductive reasoning for student achievement in college science. Included is a strategy for the development of materials which would allow students to develop problem-solving skills. (KR)

Examined is the hypothesis that an important intellectual acquisition during adolescence is the ability to generate arguments that involve reasoning to contradiction. Implication for hypothesis teaching at the elementary grades is discussed. (KR)

Identified are potential dichotomies that must be confronted by the would-be popularizer of science--science and technology, the applications and misapplications of science, simplification and complication, certainty and speculation. The importance of writing scientifically is urged. (KR)

The demonstrations presented in this article relate to everyday life, address interdisciplinary aspects, and have implications for the life sciences. Topics of the demonstrations are electricity calculations, astronomy, electrolysis of water, ester synthesis from butyric acid and pentanol, catalysis, and minerals. (PR)

The purposes of this paper are (1) to demonstrate that medical microbiology laboratory exercises should be presented with a focus on medical applications, not just traditional microbiology and (2) that exercises devoted to differential diagnostic decision making can be used to enhance the problem solving of students. (PR)

Examines the following five teaching techniques that have strong motivational value: (1) study groups, (2) group projects, (3) sharing information, (4) computer-assisted instruction, and (5) field trips. (PR)

Details a project developed to provide stimulating science classroom environments as incentives to draw talented science majors into teaching. Focuses on the experiences of one student. (DDR)
