Describes a new method of evaluating multiple choice examinations by measuring the entropy state of a student's examination above the "thermal background level," and shows that the entropy grade contains standard scoring as a special case. (Author/GA)

The performance of college students in introductory physics courses has been studied using conventional examination procedures as a measure of content mastery. Retesting over the same physics content using repeatable equivalent examinations results in a significant increase in the students mastery of physics. (Author/GS)

Discusses perceived difficulty of subjects and the comparison of standards of the examinations in different subjects. (SL)

Reported is a study to measure the degree to which children have developed an understanding of basic physics. The instruments contained items in a multiple choice format with a stem picture depicting an actual happening and three choice pictures, one of which was true in relationship to the stem. Items for the test were drawn from basic science…

THESE LESSON PLANS WERE DEVELOPED, ALONG WITH OTHER MATERIALS SUCH AS (1) DEMONSTRATIONS, (2) FILMS, (3) FILM CLIPS, (4) KEY QUESTIONS, AND (5) POSTERS, FOR USE IN A STUDY TO DETERMINE THE RELATIVE LEVELS OF UNDERSTANDING OF CERTAIN CONCEPTS OF FORCES ACHIEVED BY PUPILS IN GRADES 2-6. EVALUATION WAS MADE BY MEANS OF PAPER-AND-PENCIL…

The three purposes of this study were (1) to evaluate a paper-pencil test of critical thinking skills using physical science content, (2) to compare the effectiveness of Physical Science Study Committee (PSSC) and non-PSSC physics programs in developing critical thinking skills, and (3) to identify teacher-pupil verbal interaction behaviors that…
