Our nation's bleak economic situation has forced state governments to cut educational funding. While funds are decreasing, accountability for student achievement remains high. The No Child Left Behind Act (NCLB) forces each state to create and implement an accountability system of rewards and sanctions based on standardized test scores. In…

This paper describes a study aimed to identify most common impediments related to the introduction of an open-source mathematical software package GeoGebra. We report on the analysis of data collected during a three-week professional development programme organised for middle and high school teachers in Florida. The study identified challenges…

The described study investigated the effectiveness of an e-learning Web 2.0 course redesigned from the perspective of cognitive load theory. The analyzed variables were course wiki design features, levels of instructor support, levels of cognitive load and engagement, and values students placed on particular pedagogical approaches used during…

A special case of examinee choice, the Optional Essay Problem, is examined from the point of view of test equating. The Optional Essay Problem involves equating essay scores when the examinees are required to select an optional essay topic from a list of topics in addition to taking a mandatory test required of all examinees. The conditions that…

The Johnson O'Connor Research Foundation, which produces vocabulary instructional materials for test takers, is in the process of determining the difficulty values of nontechnical words in the English language. To this end, the Foundation writes test items for vocabulary words and tests them in schools. The items are then calibrated using the…

In this study, the ability of test development staff to predict the difficulty of analogy items was explored. The nature of the item attributes that contributed to test writers' predictions of difficulty as well as actual item difficulty was also investigated. The two expert test writers studied were quite good at predicting item difficulty. Item…

Item bias has been a major concern for test developers during recent years. The Mantel-Haenszel statistic has been among the preferred methods for identifying biased items. The statistic's performance in identifying uniform bias in simulated data modeled by producing various levels of difference in the (item difficulty) b-parameter for reference…

Results support the general conclusion that the disposition to respond in either a reflective or impulsive fashion influences the problem-solving efficiency and strategy behavior of elementary school children. The relative impact of cognitive style on problem solving varied with developmental level and the type of problem solved. (Author/BJG)

This study attempts to develop a satisfactory child version of the linguistic task of judging grammaticality. With a nondifferentially reinforced forced-choice procedure, it was found that responses of 48 children (aged 5 and 7) varied as a function of the grammatical complexity of stimulus sentences. (Author/GO)

Validation studies of learning hierarchies usually examine whether task relationships posited a priori are confirmed by student learning data. This method was compared with a non-posited task relationship where all possible task relationships were generated and investigated. A learning hierarchy in a seventh grade mathematics study reported by…

Questions concerning the ontogeny of the planning process and its role in the regulation of behavior have been markedly absent from the literature. The present study examines the planning done during solitary play by middle-class children from four public nursery schools in Athens, Greece. One hundred preschool children in five age groups (42, 48,…

This study replicates Siltanen's (1986) investigation of four developmental stages of metaphor comprehension and tests the effects of two levels of context on children's ability to comprehend metaphors. A total of 159 subjects ranging in age from 6 through 12 years were asked to provide an open-ended response to 16 test metaphors which varied in…

Concern has been expressed over the item response theory (IRT) assumption that a person's ability can be estimated in a unidimensional latent space. To examine whether or not the response to an item requires only a single latent ability, unidimensional ability estimates were compared for data generated from the multidimensional item response…

An experimental study investigating the interaction of linguistic complexity and performance in child language acquisition tests the hypothesis that children learning a first language acquire relatively complex sentences somewhat later than less complex sentences. In one of three tests, the subjects, 44 children aged 3.6 to 6 years, were presented…

Students' evaluations of a lesson were made on the same videotaped lesson after students were informed that the lesson was difficult or that it was easy, and after they were given a hard or easy content test. A two-way factorial design was employed with 92 undergraduate students, who were randomly assigned to conditions. After all students…
