Empirical evidence is presented related to the effects of using a stratified sampling of items in multiple matrix sampling on the accuracy of estimates of the population mean. Data were obtained from a sample of 600 high school students for a 36-item mathematics test and a 40-item vocabulary test, both subtests of the Iowa Tests of Educational…

A review of the literature on the influence of testing on learning and retention reveals the need for more comprehensive research findings in this regard. This study was designed to investigate further the direct effects of tests in contrast with no tests on learning and retention in ongoing college-level classes with both the instructor and the…

Testing the assumption that textbooks were getting harder while students' abilities have been declining over the years, a study was conducted to determine the readability levels of six college reading textbooks across three editions to see if they were equal or the same in readability. The study also sought to determine whether these texts were…

Many factors influence the comprehension of a linguistic act by a listener or reader. Some, such as maturity, background, and interests of the decoder are nonlinguistic; others, such as the vocabulary and complexity of the morphological and syntactical structures are linguistic in nature. A review of the literature reveals that while studies have…

Growth of administrative components in 43 K-12 public school districts in the Saint Louis metropolitan area is reported for 1968-76. Increases in absolute numbers and ratios of administrators to teachers occurred in school districts with increasing as well as declining enrollments. Statistical analysis of public records and interviews with…

This paper analyses new methods of teaching skiing in terms of a computational paradigm for learning called increasingly complex microworlds (ICM). Examining the factors that underlie the dramatic enhancement of the learning of skiing led to the focus on the processes of simplification, debugging, and coaching. These three processes are studied in…

An outline is given of a model procedure by which teachers can ascertain the reading level of students so they may match the students' ability in reading comprehension with the subject content of a course. This six-step model may be viewed as a continuum of material and student assessment, teaching, evaluation, and reassessment of material and…

Path analysis was used to reanalyze Kropp and Stoker's data from tests designed to evaluate Bloom's taxonomy of educational objectives in the cognitive domain. Scores for 1,128 students in grades nine through twelve were analyzed separately by grade level for four content areas on six taxonomic levels. A measure of general ability was also…

Problems and procedures in assessing and obtaining fit of data to the Rasch model are treated and assumptions embodied in the Rasch model are made explicit. It is concluded that statistical tests are needed which are sensitive to deviations so that more than one item parameter would be needed for each item, and more than one person parameter would…

A model is proposed for memory that stresses a distinction between episodic memory for encoded personal experience and semantic memory for abstractors and generalizations. Basically, the model holds that questions influence the nature of memory representations formed during instruction, and that memory representation controls the way in which…

On the basis of past research efforts to improve multiple-choice test information through differential weighting of responses to wrong answers (distractors), two statistical indices are developed. Each describes the properties of response distributions across the options of an item. Jaspen's polyserial generalization of the biserial correlation…

This guide explains the concept of out-of-level testing and suggests a formula for estimating the occurrence of floor effects and ceiling effects, within the context of models for evaluating Elementary Secondary Education Act (ESEA) Title I programs. An analogy explains floor and ceiling effects as if test items are stored in different levels in a…

To analyze test item and person interactions according to the Rasch Model, 822 incoming community college freshman were administered the New Jersey Basic Skills Placement Test. The Logical Relationships and Elementary Algebra subtests were chosen to examine the effect of differing average item difficulty on descriptions of fit statistics and on…

The objectives of this investigation are to develop, describe, assess, and demonstrate procedures for constructing mastery tests to minimize errors of classification and to maximize decision reliability. The guidelines are based on conditions where item exchangeability is a reasonable assumption and the test constructor can control the number of…

In order to discern the manner and determinants of instructional grouping both within and across classrooms of varying characteristics, this investigation employs a "multi level" approach. Specifically, an attempt was made to answer the following questions: How do the expenditure levels of school districts and the economic backgrounds…
