In developing a physics course that would capture medical student interest at the University of Queensland (Australia), it was discovered that there is minimal correlation between students' interest in a subject and perceptions of its difficulty but strong correlation between interest and perception of its relevance to clinical studies.…

Researchers examined the effect of writing in response to simple and complex pictures on students' narrative writing. Findings indicated that fourth graders use different composing behavior and produce different written products than do sixth graders, writing more coherently/cohesively for complex than for simple tasks. (SM)

A survey of teachers' and students' perceptions of the difficulty of learning American Sign Language (ASL) suggested that teachers generally rated the learning difficulty levels higher than students, and both groups cited such sociolinguistic and affective problems as cultural inhibitions, interacting with the deaf, and attitudes and motivations…

Performance of a common set of test items on an examination in which the order of options for one test form was experimentally manipulated. Results for 759 medical specialty board examinees find that reordering item options results in significant but unpredictable effects on item difficulty. (SLD)

This study of 325 adolescents with deafness found that students who attended more classes and more academically demanding classes had higher achievement levels across placement categories. The cumulative effect of mainstream placement may be, in part, a product of different patterns of educational programing. Race was also a factor in achievement.…

Discusses areas where teachers may harbor mistaken assumptions about their students' understanding when using graphing calculators: (1) confidence and competence with order of operations, (2) integration of algebraic and graphical knowledge, and (3) scaling a graph. (MKR)

Illiterate immigrant adults (n=14) in France were assessed on ability to master three metalinguistic tasks: judgment of phonological length of words, initial consonant deletion, and lexical segmentation of sentences. Performance of illiterates and partial illiterates dramatically improved after training which involved corrective feedback and…

Some factors that should be considered when science teachers produce materials for their students are presented. Readability and the key aspects of language (vocabulary, sentence structure, textbook or examination style, and organization and presentation) are discussed. Directions and the graph needed for estimating the reading level of materials…

Discusses the selection of material for vocal performances by high school students. Describes adolescent voices as young with little vocal technique and only partially developed or unused register. Includes considerations of breath management, tessitura, energy, subject matter, and language. Provides a list of songs meeting appropriate…

The recommendation that the reliability of multiple-choice tests will be enhanced if the distribution of item difficulties is concentrated at approximately 0.50 is reinforced and extended in this article by viewing the 0/1 item scoring as a dichotomization of an underlying normally distributed ability score. (SLD)

Forty deaf high school students defined words from the Peabody Picture Vocabulary Test and then ranked missed words in terms of expected difficulty level. After judging the accuracy of the rank-order judgments, it was determined that deaf students were unable to judge their feeling of knowing, but two hearing groups were able. (Author/JDD)

A pilot experiment examined ambiguity in English-as-a-Second-Language (ESL) learning by graduate and undergraduate students. The findings revealed that most ESL speakers have greatest difficulty in understanding sentences with derived-structure ambiguity. Underlying-structure ambiguity was the next most difficult to understand, followed by lexical…

This study, involving 59 disabled and nondisabled adolescent readers, tested A. Kennedy's "spatial map" hypothesis wherein spatial sequencing ability is important in lexical reaccess under high-demand text situations alone. Tests of the variance contributions of a spatial sequencing covariate to eye movement dependent measures of reading, across…

This paper reviews research on disturbances of children with developmental delays and handicaps in responding to complex stimuli, suggesting that such disturbances may deleteriously influence behavioral/neurophysiological development. Intervention programs for teaching children with autism a generalized set to use in responding to complex…

Discusses hierarchical complexity of tasks as a way of conceptualizing information in terms of the power required to complete a task, and its implications for developmental psychology and information science. Provides an analytic solution to the definition of developmental stages and allows for the possibility within the science of scaling the…
