Testing--1,2,...523,...641,...999--Testing: The MDT Multi-Digit Technique Applied to Science Education.
Anderson, Paul S.; Schoner, James S.
The MDT multi-digit technique, a development in testing technology, is described; and its application to science classrooms is discussed. Some actual materials for use in a cell biology class are included. The primary characteristic of an MDT multi-digit test is a long list of possible responses, with each term marked with a three-digit number that can be marked on the response grid or on a computer-scored sheet. Up to 1,000 alternative answers may appear on a single sheet. A single list can often be sufficient for an entire course because it is the "answer blank" for thousands of questions. The MDT method has been used in university courses with over 6,000 students in a number of disciplines. More than half the students found the method as desirable as or more desirable than other testing methods. A sample test for cell biology is provided, and instructions are given for making an answer key for hand scoring. A software system for machine-scoring has recently become available, and software under development will address issues of higher order thinking more fully. The MDT method has considerable potential for analysis, feedback, academic rigor in testing, and time savings for teachers. Two figures illustrate test application. (SLD)
