单片机课程教学改革探索

传统的单片机教学不能适应新形势下职业教育的培养目的,本文论述了单片机教学改革的必要性,并就改革教学内容、教学方法、实验实训方法和考核方式等方面作了一定的探索。     

Learning activities and interactive videodisc: an exploratory study

This article reports the findings of a small-scale study on pupil use of interactive videodisc. The types of learning activity in which the groups of pupils engaged are identified and the proportion of time spent on each is shown. Patterns in the data are analysed by ability of the pupil group and by the number of sessions in which the videodisc had been used. The discussion focuses on two interesting results: the high proportion of time spent on reading, watching and listening; and the greater statistical differences within groups than between groups of pupils.     

The efficiency and effectiveness of an interactive videodisc system to teach sign language vocabulary

Forty students enrolled in the course 74.153, Introduction to Sign Language, at Bloomsburg University of Pennsylvania participated in a study using an interactive videodisc system to teach sign language vocabulary. The experimental group (n = 20) learned signs via an interactive videodisc system while the control group (n = 20) learned the same signs through a traditional classroom approach. Results indicated no significant differences between the groups in their ability to recognize signs. In addition, the experimental group took one-third less time to learn as many signs as the control group.     

The role of the microcomputer in science teacher preparation

This article is dedicated to the memory of the author who died on June 7, 1990. Dr. Mandall contributed regularly to literature on the educational uses of computers, often describing practical ways of using computers and programing to engage students in reasoning and problem solving in mathematics and science. He was an innovator who will be missed.
