In this paper a class of regular surfaces, generated by rotation and twist of a rigid line segment, is considered. Firstly a complete description of those surfaces by means of local charts is obtained and then its orientability is characterized in terms of the number of half-twists, taking into account their direction (clockwise or…

Students of Architecture and Building Engineering Degrees work with Computer Aided Design systems daily in order to design and model architectonic constructions. Since this kind of software is based on the creation and transformation of geometrical objects, it seems to be a useful tool in Maths classes in order to capture the attention of the…

A British project in engineering science is described. Computer assisted instruction packages are being developed to provide students with experience with models or systems of models related to lecture material on electrical, electronic, nuclear, and mechanical engineering. (SD)

By using a computer to simulate experimental situations, engineering laboratory courses can provide more ambitious experiments as well as experiments demanding more calculations. (SD)

Two methods of teaching mathematics to engineering students were investigated. The first used tutorials, written materials, and lectures, while the second used computer exercises instead of tutorials. Both were effective with students entering the program with low mathematics achievement. (SD)
