Abstract
We propose to instruct engineering exercise in the part of information processing including electric engineering, mathematics, information basics, and experiments. We give first year students four themes for exercise; (1) the trigonometric function, (2) the solving equations, (3) Fourier series, and (4) the model of electric field in the dielectric materials. The used software is Microsoft Excel on Windows XP. At the fourth theme, all the students are arranged as lattice points of a model case, and work together to calculate voltage values by desk calculators. The results from their handwork are compared to simulated values of the Excel software. In each theme, the graphical method of simulated values leads students to understandings of theories and phenomena.
