Optometry educators can be assisted in making complex concepts understandable to students by using rhetorical devices such as metaphors, similes, analogies, parables, and allegories. As an example, the difficulties in communicating everyday but complex clinical concepts regarding inflammatory disorders are discussed and use of rhetorical devices…

Current coaching practices used in training test wiseness for analogy items on standardized test batteries were investigated in a 3-group design involving about 100 undergraduates in each condition. The largest improvement came in items in the middle range of difficulty, but overall effects of coaching were important. (SLD)

Teachers and parents of 45 students (ages 8-17) with learning disabilities completed the Homework Problem Checklist. The study found that students with learning disabilities experienced nearly two and a half times the level of difficulty with specific homework problems as their nondisabled peers. (JDD)

Two groups of 10 adult aphasics received auditory-verbal "yes-no" questions, including egocentric, environmental, pictorial, and relationship items, either in a consistent order or random order. Support was found for the existence of a hierarchy of difficulty among the types of questions, but there was no significant difference between…

A meta-analysis of the difficulty and discrimination of the "none-of-the-above" (NOTA) test option was conducted with 12 articles (20 effect sizes) for difficulty and 7 studies (11 effect sizes) for discrimination. Findings indicate that using the NOTA option does not result in items of lesser quality. (SLD)

Adolescents and young adults (n=120) were assessed on their use and understanding of concordant and discordant adverbial conjuncts. Results demonstrated an increasing ability with age to use and understand these words in the written mode, with mastery in usage trailing understanding. Concordant and discordant conjuncts were equally difficult.…

A 3-year study involved having 19 fifth and sixth grade students attend school with Russian peers for 10 days and, later, having Russian students attend U.S. schools. Findings indicated that the Russian students perceived greater difficulty in a differentiated curriculum for gifted students than did the U.S. sample. (DB)

This study with 56 students (mean age 15 years) with mental retardation and 53 nonretarded students (matched for mental age) found that students with mental retardation were more likely to rely on all kinds of external cues (task-relevant, incidental, or misleading) in problem solving, especially when the preceding task had been difficult.…

This study of the haptic processing of 9 children with specific language impairment and 9 normal-language children (ages 5-7) found that both groups performed similarly when the response modality was tactile and task requirements were minimal and performed differently when response demands included cross-modal processing or increased symbolic and…

Comparison of problem preferences of six meaning-oriented and five number-oriented junior high school students found that the successful meaning-oriented students preferred solving multistep and nonroutine problems, whereas the less successful number-oriented students preferred simple routine problems. However, in graded situations all students…

Studies with 174 college students and 41 college faculty attempted to define trick questions and to determine whether students could distinguish between trick and not-trick questions. Evidence seems to suggest that the concept of trickiness is not as clear as some test construction textbooks indicate. (SLD)

Comparison of disfluent conversational utterances of 14 children who stutter and 14 children (mean age of both groups 52 months) who do not stutter found that for both groups, disfluency clusters were typically produced at clause onset and within the most complex linguistic contexts and that they reflect the effects of producing multiple syntactic…

Examined whether providing item review on a computerized adaptive test could be used by examinees to inflate their scores. Two studies involving 139 undergraduates suggest that examinees are not highly proficient at discriminating item difficulty. A simulation study showed the usefulness of a strategy identified by G. Kingsbury (1996) as a way to…

Describes the PMOSE/IKIRSCH document readability formula, which provides a measure of document complexity (looking at structure and density) of a wide array of different document types (including lists, schedules, tables, graphs, charts, indexes, time lines, maps, calendars, and forms). Discusses implications of the formula in terms of document…

The latency and amplitude of the P300, an event-related potential, during the performance of a memory-scanning task were used as indices of the efficiency of information processing that may mediate individual differences in intelligence. Results with 61 female college students contradict a pure speed of processing explanation of the relationship…
