COMPUTER APPLICATIONS
研究了微型计算机如何加速课堂材料展示并提升视觉清晰度，电子表格软件便于教师灵活准备和演示经济变量互动，但个人准备时间较长，出版商提供格式化教材可促进推广。
The microcomputer can accelerate the display of classroom material and enhance its visual clarity. Recent display methods have permitted viewing by classes of up to 100–150 students, and this size is increasing with improvements in display resolution. An electronic spreadsheet such as Lotus 1–2–3 enables instructors to prepare materials with relative ease and flexibility, and in‐class use facilitates the demonstration of interactions among changing economic variables. The preparation time for individual instructors is substantial, however. Computer assisted lectures could become more widespread if publishers were to provide textbook tables, figures, etc. formatted for computer input.
