A study investigated the interrelationships among warrants, argument dimensions, and perceived argument effectiveness. Warrants were operationalized as analogies, examples, and causal warrants, while argument dimensions were defined as degree of logicality, emotionality, and ethicality. Based upon prior research, weak and strong arguments were…

The effect of dimensionality on an adaptive test's ability estimation was examined. Two-dimensional data sets, which differed from one another in the interdimensional ability association, the correlation among the difficulty parameters, and whether the item discriminations were or were not confounded with item difficulty, were generated for 1,600…

A study explored the effects of both prior knowledge of acronyms and their form of presentation (cued or uncued) on reader recognition of acronym meaning. Among the hypotheses tested were that (1) a reader presented with an acronym ranked as familiar is more likely to recognize that acronym than one ranked unfamiliar, and (2) that a reader…

The diversity of textbook and scholarly book reviewers makes it difficult for an author to deal with reviews in any systematic or preplanned manner. There are, however, several helpful working assumptions: (1) the reviewer is always right, (2) the author is always right in principle but frequently wrong in practice, (3) the publisher wants what…

While a child's eligibility to enter kindergarten is usually based on chronological age, public schools are increasingly concerned about children who appear not ready for a regular kindergarten program. Alternative programs, often termed "developmental" kindergartens, have developed rapidly over the past few years, largely under local school…

During the last 2 years (1980-82), selected schools in the Broward County School District in Florida participated in the National Sex Equity Demonstration Project (NSEDP) to create a model for demonstration of curricular materials, educational practices, and program arrangements that feature gender-fair instruction and associated educational…

To discover the components of a trustworthy source, a study evaluated the credibility of health-related news stories. Subjects, 192 college undergraduates, read one of four random versions of a one-page newspaper story about aspirin's ability to ward off heart attacks. They were told that the sources for the articles were: a medical journal (high…

Television politics, emphasizing emotions over rational decision making, has been accused of warping the political process, especially in the election of the president. In the incomplete medium--the collection of dots--that is television, the viewer completes the circle of communication, filling in the image with his or her own attitudes. The…

On the basis of a National Humanities project proposed by the English department of a St. Louis, Missouri high school, many different approaches to drawing students into writing about and understanding literature were developed. One of three such techniques is a sequence of writing-reading-writing that offers the possibility of both enhancing the…

This paper reviews the application of the EM Algorithm to marginal maximum likelihood estimation of parameters in the latent class model and extends the algorithm to the case where there are monotone homogeneity constraints on the item parameters. It is shown that the EM algorithm can be used to obtain marginal maximum likelihood estimates of the…

The efficacy of the random digit dialing method in telephone surveys was examined. Random digit dialing (RDD) generates a pure random sample and provides the advantage of including unlisted phone numbers, as well as numbers which are too new to be listed. Its disadvantage is that it generates a major proportion of nonworking and business…

The results of a survey which sought to determine the science education research needs of elementary teachers are discussed in this report. The survey was intended to provide science education researchers with information on what research areas might be of greatest interest to elementary teachers. The sample consisted of 553 elementary teachers in…

A total of 22 girls and 22 boys nearly equally divided between preschool and second-grade levels were asked to give three responses to each of 20 questions concerning what could make them--a same-sex child, an opposite-sex child, and an adult--feel happy, sad, angry, afraid, or surprised. Responses were feel happy, sad, angry, afraid, or…

A timely and coordinated system to conduct placement and followup studies was developed by Hillsborough Community College. The project was intended to increase the response rate of program completers and leavers and the placement rate of program completers in order to meet the placement rate set by the 1983 Florida legislation. Vocational faculty…

Child abuse involves more than the use of corporal punishment with a child. Investigators have measured parents' emotional reactivity and attributions in relation to aversive child behavior. A "video recall" procedure has been used for assessing affective responding of adults engaged in marital conflict and has been valid for obtaining…
