IntroductionOver the past two years, several large classrooms at the Faculty of Applied Science andEngineering, University of Toronto were upgraded through installation of electronic capabilities.This has allowed teaching techniques to be expanded and improved. For instance, in the pastyear, the author used these facilities in teaching an undergraduate vibrations course to a class ofmore than 100 students.This paper describes the material prepared for the vibrations course, using the electronicclassrooms, including:. a series of computer animations to illustrate various important aspects of vibration phenomena, based on a computer software package entitled Working Model’, which

As with many software programs, the location of various commands takes experience to master5. The menu options must be examined in detail, because often one item can be accomplished several different ways. This exercise was designed to

. Aftermoving to Grand Valley State University, I found myself teaching Statics again. To make thecourse more interesting, I decided to explore some creative teaching methods. Some explorationof departmental resources made it clear that computers would be a good avenue to pursue. Uponexamination of the available equipment, it became obvious that it would be possible to makeextensive use of computers in teaching. Not only were faculty well equipped, but the student tocomputer ratio was 5: 1. In the end the course was developed to include extensive computer use inand out of class.It is my intention to describe my experiences, and make suggestions to other faculty thinking ofusing computer tools to support their classroom activities.1.1 - Computer Use In

Graphics A review of the old syllabus for CS321 shows that it follows a fairly traditional approachfor computer graphics courses. The course discusses the idea of raster display techniques,reviews some basic mathematics, introduces line and other drawing algorithms, discussespolygons and fill strategies, and then moves into transformation techniques and clipping andeventually covering 3-D objects. Along the way additional information is shared on the ideas ofcurves, text, color, and shading. This is common approach in such texts as Hearn and Baker[1]and Foley, et al.[2]. This achieves the goal of introducing a number of mathematically wellunderstood algorithms and places sufficient emphasis on how to look for and handle specialcases

The rater takes a piece of writing and either (1) matches it with another piece in a graded series of pieces or (2) scores it for the prominence of certain features important to that kind of writing or (3) assigns it a letter or number grade. The placing, scoring, or grading occurs quickly, impressionistically, after the rater has practiced the procedure with other raters. The rater does not make corrections or revisions in the paper.

A spark timer is connected to the apparatus so that as the bob drops a tiny mark is burnedon a waxed paper tape at 1/60 second intervals. Position-time data was used to determine theaverage velocity of the falling object in each prescribed interval of time. Students then plotted,by hand, a graph of average velocity of the falling object versus time. From the slope of the linestudents were able to determine the acceleration due to gravity.

These tests assess mathematical, logical, and word usage skillsto determine intelligence. It wasn’t until 1983 that Howard Gardner, a Harvard psychologist,challenged the concept of a single measure of intelligence. He proposed a broader definition ofintelligence which included the existence of at least seven basic intelligences, all of which wouldfocus on the capacity for problem solving and fashioning products in a context-rich andnaturalistic setting.
