We explore the conditions under which short, comparative interrupted time-series (CITS) designs represent valid alternatives to randomized experiments in educational evaluations. To do so, we conduct three within-study comparisons, each of which uses a unique data set to test the validity of the CITS design by comparing its causal estimates to…

There is evidence that pre-tests can have orienting and motivational and teaching functions - in addition to the sought-for testing function. There is also evidence that these additional functions can be either general or specific. The present paper contributes to the ongoing debate by discussing the issues involved in the context of a series of…

The development of a project to assess the effectiveness of schools in a large urban school district is described in this paper, with a focus on improving the validity of school effectiveness instruments.

Although actual or projected satisfaction with parenting is important in determining whether a couple will become parents and how large their family will be, only minimal research has assessed parental satisfaction. The Cleminshaw-Guidubaldi Parent Satisfaction Scale, a 50-item Likert-type instrument designed to measure components of satisfaction…

Two types of sensitivity indices were developed in this paper, one internal to the total test and the second external. To evaluate the success of these statistics the three criteria suggested for a satisfactory index of item quality were considered. The Internal Sensitivity Index appears to meet these demands. Certainly it is easily computed. In…

To determine the long-run impact of the CERLI training program, the trainees' abilities to function as Specialists in Continuing Education (SCE) had to be measured and assessed. This assessment is a followup to "Assessment of the CERLI Training Program Specialist in Continuing Education" (EA 002 706). The document reports on attempts to…

To investigate the assertion that there is a tendency for teachers to emphasize skills already mastered by their students, data were collected on 488 seventh grade mathematics students in three junior high schools. Of these, 285 were assigned to experimental classes taking the curriculum under development and 203 were assigned to comparison…

An elementary survey of item characteristic curve theory, centered around the problems of individualized (tailored) testing, is presented. Following the introduction, discussions are provided of the following: Test Theory for Itemized Tests; The Guttman Scale; Item Characteristic Curve Theory; An Alternative Model; Specialization, Application, and…
