Retention of Electronic Fundamentals: Differences Among Topics.
Johnson, Kirk A.
Criterion-referenced tests were used to measure the learning and retention of a sample of material taught by means of programed instruction in the Avionics Fundamentals Course, Class A. It was found that the students knew about 30 percent of the material before reading the programs, that mastery rose to a very high level on the immediate posttest, and that about half of the improvement was lost by the end of the course (an interval of about 96 days). There was considerable variation in item difficulty by the end of the course. Most of this variation was independent of topic difficulty or measures of time difficulty obtained from the early posttests. Instructors (who were also experienced technicians) were asked to indicate the items that were most relevant to subsequent instruction or to performance on the job. These ratings were not very reliable. The indicated items did not differ appreciably from the remaining items in terms of student proficiency. It was concluded that if the instructors were correct in their ratings, there was enough forgetting to hinder a number of students in learning from subsequent courses and in performing their assigned duties on the job.
