Teachers' professional knowledge is assumed to be a key variable for effective teaching. As teacher education has the goal to enhance professional knowledge of current and future teachers, this knowledge should be described and assessed. Nevertheless, only a limited number of studies quantitatively measures physics teachers' professional…

Content characteristics of 1,400 Graduate Record Examination (GRE) analytical reasoning items were coded for item difficulty and discrimination. The results provide content characteristics for consideration in extending specifications for analytical reasoning items and a better understanding of the construct validity of these items. (TJH)

The construct validity of algebra word problems for measuring quantitative reasoning was examined, focusing on an analysis of problem attributes and on the analysis of constructed-response solutions. Constructed-response solutions to 20 problems from the Graduate Record Examinations (GRE) General Test were collected from 51 undergraduates.…

Specific questions addressed in this study include how time limits affect a test's construct and predictive validities, how time limits affect an examinee's time allocation and test performance, and whether the assumption about how examinees answer items is valid. Interactions involving an examinee's sex and age are studied. Two parallel forms of…

The keylist format (rather than the conventional multiple-choice format) for item presentation provides a machine-scorable surrogate for a truly free-response test. In this format, the examinee is required to think of an answer, look it up in a long ordered list, and enter its number on an answer sheet. The introduction of keylist items into…
