Three experiments investigated effects of complexity on 2- to 6-year-olds' understanding of a beam balance. Found that 2- to 4-year-olds succeeded on problems that entailed binary relations, but 5- and 6-year-olds also succeeded on problems that entailed ternary relations. Ternary relations tasks from other domains (transitivity and class…

Compares the influence of text difficulty on the growth of poor readers' reading ability over 18 weeks of 1-to-1 tutoring. Significant differences favored tutored children. Between approaches, the only significant difference was oral reading fluency, which favored students who read material at their reading level. Students who began with lower…

Discusses the complexities of teaching and teacher education, examining circumstances that change the ways in which researchers view teaching and teacher education. The article also presents cautionary thoughts about the tendency to narrow the scope of research to focus only on the spaces immediately relevant to a pressing problem framed by…

Examined the behavior of item and person statistics from item response theory and classical test theory frameworks through Monte Carlo methods with simulated test data. Findings suggest that item difficulty and person ability estimates are highly comparable for both approaches. (SLD)

The investigation of interactions between the abilities of stimulus discrimination and simple learning and two instructional variables (discrimination difficulty and degree of overlearning) with 27 mentally retarded adolescents found an interaction between stimulus discrimination and the number of words presented at one time for learning…

Visual and auditory coding processes in learning-disabled students (SLDs, n=19) and control students (SCs, n=19) were examined. Analysis of decision latencies revealed that with initial task exposure, SLDs responded more slowly than SCs, but confusability patterns were similar. With practice, overall latencies became comparable, while…

The effect of 3 item arrangements (easy to hard, hard to easy, and random) on test anxiety was studied using an actual classroom examination administered to 126 graduate students (36 males and 90 females) under power conditions. Results indicate that anxiety level and test item arrangement are related. (TJH)

The characteristics of unidimensional ability estimates obtained from data generated using multidimensional compensatory models were compared with estimates from non-compensatory item response theory (IRT) models. The least squares matching procedures used represent a good method of matching the two multidimensional IRT models. (TJH)

An analysis of syntactic complexity was performed on spontaneously generated oral stories obtained from 93 learning disabled (LD) and normally achieving (NA) students at age levels from 8 through 13 years. Results indicated almost identical rates of correct usage and similar patterns of usage between LD and NA subjects on all measures. (Author/DB)

Reviews procedures followed during traditional organizational change and identifies factors that lead to increased intrinsic motivation. Topics discussed include problem solving, level of challenge, competence, people as information processors, curiosity, task complexity, the need for organization, and choice in degree of control.

The differential effects of idea levels of pre-writing questions and number of questions upon measures of elaboration in writing were examined. The interaction between the level and number of pre-writing questions and processing time in three writing experiments with a total of 174 undergraduate students was assessed. (TJH)

An expert system administered study questions from the Certified Public Accountant (CPA) and Certified Management Accountant (CMA) exams and others designed for textbooks to 113 accounting students. CPA/CMA questions were more difficult (71% correct compared to 74% for others); CMA questions were more challenging than CPA ones (67% to 73%…

The concept of item discrimination is generalized to the case in which more than one ability is required to determine the correct response to an item, using the conceptual framework of item response theory and the definition of multidimensional item difficulty previously developed by M. Reckase (1985). (SLD)

An instructional design model defining instruction as creation of a learning environment that supports learners' construction of knowledge was tested with 32 learners. Findings suggested that the learning environment was effective in supporting learners' construction of complex knowledge structures. (SK)

This study, involving 24 preschool children with stuttering problems, found no significant differences between subgroups based on stuttering severity and phonologic ability. Phonologic difficulties of the disfluent word, and the fluent word following it, did not contribute to fluency breakdown regardless of the children's stuttering severity or…
