In spite of many inherent problems, impact evaluation should remain an integral part of program evaluation, both because impact evaluation brings its budget justification with it, and because its focus on causal hypotheses is an essential part of evaluation. Methodology based on the author's body of work is reviewed. (SLD)

Critiques an article that compared genuine suicide notes with simulated notes. Elaborates on theoretical and methodological difficulties, noting a lack of hypotheses, operationalized constructs, and prediction testing. Examines the operational design used in the article and suggests that the study of suicide notes in such a fashion should cease.…

In two studies, college students and sixth and ninth graders determined a hypothesis from data and were given opportunities to gather further data and test the hypothesis. Little evidence for students' confirmation bias, or tendency to avoid seeking and considering data that disconfirmed the hypothesis, was found. (BC)

The degree to which reading ability and intelligence, as measured by the Raven Progressive Matrices Test, were related was studied for 486 students in grades 2 through 12 in a small town, rural school system.

Describes an intensive 2-week Operation Physics Institute at Western Washington University for 67 elementary and middle school teachers designed to improve science instruction. Presented several discrepant events in physics; teachers explained the events with scientific methods with the aid of concept lists. (KS)

Meta-analysis of 225 hypothesis tests of measures of memory for order (MFO) and the relationship of MFO and measures of general ability demonstrate a significant relationship between MFO and standardized test scores. Fifty-one independent samples were tested. MFO task quality was a significant predictor of effect size. (SLD)

This study examined whether numbers of unwarranted assumptions, hypotheses, and requests for additional information concerning a hypothetical case of child abuse and neglect (CAN) predicted agreement with a premature decision to remove a child from home among 141 CAN professionals.
