To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a…

Derives formulas for the validity of predictor-criterion tests that hold for all test scores constructed according to the expected-value concept of true score. These more general formulas disclose some paradoxical properties of test validity under conditions where errors are correlated and have some implications for practical testing situations…

This study was designed to evaluate the instructional effectiveness of the introductory units (Programs 1-25) of the Trimodal Programmed Instruction in Reading. (Editor)

Attempts to select empirically the optimal cutting score or criterion level for a test based on response data from validation samples of instructed and uninstructed students. This score maximizes the probability of correct mastery-nonmastery decisions (or minimizes the probability of incorrect decisions). (Author/RK)

The fakability of responses to the Attitude Toward Disabled Persons Inventory (ATDP) was investigated through applying two criteria requiring subjects to identify the favorable responses and three using "honest" test - "faked response" retest techniques. Considerable differences were noted among the items identified as…

A criterion-referenced measuring instrument was developed from a national survey of quantitative skills/concepts required by entering first grade students and individually administered to 273 children three to six and one-half years of age. By comparing mastery age of each of the 153 skills/concepts, sequential patterns of development were made…

To investigate the effectiveness of integrating abstract and realistic visualization, the effectiveness of four treatments was measured for: (1) facilitating student achievement of different kinds of educational objectives; (2) students possessing different levels of student ability; (3) externally paced and self-paced methods of instruction; and…

To investigate performance patterns on strands of the mathematics curriculum, locally developed criterion-referenced benchmark tests were administered to all kindergarten through fourth graders in the Minneapolis public schools. Total test scores and strand scores were analyzed by ethnic group, gender, and socioeconomic status. (Author/BS)

The utility of the biomedical model of adjusted statistics is demonstrated. The model is recommended for use by educational researchers to randomize subjects for a more accurate estimate of school programs' success or failure when compared across classrooms or other units. (Author/MH)
