This study examined the use of rubrics in scoring a performance-based assessment. After receiving a health lesson of ways to have a healthy brain, fifth grade students were given an assignment to illustrate and write a booklet that demonstrated their knowledge of the topic. From students' responses the researchers constructed four sample papers…

Soft constraints hypothesis (SCH) is a rational analysis approach that holds that the mixture of perceptual-motor and cognitive resources allocated for interactive behavior is adjusted based on temporal cost-benefit tradeoffs. Alternative approaches maintain that cognitive resources are in some sense protected or conserved in that greater amounts…

This paper summarizes research conducted on three computer based video models' effectiveness for learning based on memory and comprehension. In this quantitative study, a two-minute video presentation was created and played back in three different types of media players, for a sample of eighty-seven college freshman. The three players evaluated…

A new report published by the Manhattan Institute for Education Policy, "The Effect of Special Education Vouchers on Public School Achievement: Evidence from Florida's McKay Scholarship Program," attempts to examine the complex issue of how competition introduced through school vouchers affects student outcomes in public schools. The…

The present study sought to examine the relationship between teacher quality and student achievement in public elementary schools in a community district school of the New York City. It has 23 elementary schools, more than 7,600 students and around 350 teachers. For this study, participants consist of a sample of 117 full-time teachers who were…

Bridging the areas of political-economic sociology, the sociology of agriculture and environmental sociology, this study tests two hypotheses derived from a refined theory of foreign investment dependence. The hypotheses state that pesticide and fertilizer use intensity in less-developed countries are both positively associated with foreign…

This study investigated potential problems associated with one method of testing English-as-a-Second-Language (ESL) skills in work settings in foreign countries. The method, used by the Australian government to assess speech skills of individuals in locations outside Australia, involves having native English-speakers carry out a series of oral…

Practical and effective methods for detecting copying of multiple-choice test responses have been available for many years. These methods have been used routinely by large admissions and licensing testing programs. However, these methods are seldom applied in the areas of standardized or classroom testing in schools or colleges, and knowledge…

Sampling distributions for ten tests for comparing population variances in a two group design were generated for several combinations of equal and unequal sample sizes, population means, and group variances when distributional forms differed. The ten procedures included: (1) O'Brien's (OB); (2) O'Brien's with adjusted degrees of freedom; (3)…

The most appropriate statistical model for the small-scale (n<100) studies common in language testing research is the Rasch one-parameter logistic model. The Rasch model provides a wide range of options for conducting research, refining existing examinations, and developing tailored (computerized adaptive) language tests. Three investigations…

This study introduced a probabilistic model utilizing item response theory (IRT) for dealing with a variety of misconceptions. The model can be used for evaluating the transition behavior of error types, advancement of learning stages, or the stability and persistence of particular misconceptions. Moreover, it apparently can be used for relating…

A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x test score x item 1 x ... x item k contingency table. If the subgroup membership is unknown, the models are the incomplete-latent-class models of S. J. Haberman (1979). The…

The use of loglinear latent class models to detect item bias was studied. Purposes of the study were to: (1) develop procedures for use in assessing item bias when the grouping variable with respect to which bias occurs is not observed; (2) develop bias detection procedures that relate to a conceptually different assessed trait--a categorical…

Lawrence Walker's (1984) meta-analysis of 108 samples concluded that there are no sex differences in stages of moral reasoning. This paper reviews Walker's work and points out that some of his analyses, however, are controversial and favored unwarranted conclusions. Walker neither tested the hypothesis that males are more advanced than females in…

Two studies are presented in this report. The first is titled "Empirical Studies of Multilevel Approaches to Test Development and Interpretation: Measuring Between-Group Differences in Instruction." Because of a belief that schooling does affect student achievement, researchers have questioned the empirical and measurement techniques…
