Subjective Scaling of Student Performance.
A method for measuring performance increments across a wide range of student performance--specifically, by measuring the student's performance in homework and classroom work. A judge evaluates the achievement level from samples of each student's work collected at the beginning and end of the program. Rating the student's work on an assignment common to all, the judge scores either by intersample relationship or by comparison to an absolute value scale. This exercise evaluates improvements in arithmetic and reading skills and affords a criterion for using the standardized tests. The specific assignment scores can be correlated with the standardized test scores. Although scaling techniques appear to be generally useful in educational evaluations, more basic research is necessary to isolate student performance variables, to study individual teacher's grading biases, to determine the various dimensions of student performance, and to identify performance changes. 15 pp. Ref.
