Item-Sampling as a Classroom Evaluation Technique.
Poggio, John P.; Glasnapp, Douglas R.
The present research was initiated to investigate whether item-sampling as a procedure would yield a more accurate and stable index of student achievement during formative evaluation when compared to indices arrived at by the traditional method of assessing pupil knowledge and understandings within the framework of multiple choice testing for student evaluation. Results have indicated that item-sampling as a method for measuring classroom achievement provides no more precise information than tests of the same length constructed in the traditional manner. It was shown that item-sampling can be employed for classroom assessment without the fear that perhaps the procedure itself would deter from some estimate of an individual's performance. The research has demonstrated that item-sampling can provide feedback to the instructor over a greater range of content objectives within the same time limits that typically provide for a narrower sampling of course related objectives by way of traditional test construction. It was also shown that item-sampling, in addition to covering a greater range of content objectives, can do so with a fewer number of items per test without losing predictive power. (Author)
