The dichotomous Rasch model was applied to verbal subtest scores on the Intelligence Structure Test Battery for 905 12- to 15-year-old secondary school students in the Netherlands. Results suggest that, if any factor is used to increase difficulty of items, that factor should be used on all items. (SLD)

In three task settings differing in difficulty and turnover rate in a truck assembly plant, structured on-the-job training (OJT) provided twice the financial benefits as unstructured OJT and required one-fifth the mastery time. Turnover rate had a greater effect on benefit size than did task difficulty. (SK)

Japanese college students (n=483) learning English as a Foreign Language (EFL) read passages in English in one of three forms: (1) native baseline; (2) simplified; or (3) elaborated. The study found that comprehension was highest among learners reading the simplified version but was not significantly different from those reading the elaborated…

The relationship of internality-externality and dominance-submissiveness to student preference for course structure and course difficulty was examined for 86 college students. Preference measures were used, which focused on specific dimensions of instruction--structure and difficulty. In contrast to some other research results, internal and…

A network-flow model is formulated for constructing parallel tests based on classical test theory while using test reliability as the criterion. Practitioners can specify a test-difficulty distribution for values of item difficulties as well as test-composition requirements. An empirical study illustrates the reliability of generated tests. (SLD)

Aims to delimit the possible individual differences in feelings of difficulty experienced in relation to mathematics. Shows that feelings of difficulty form their own system, mainly influenced by performance and cognitive ability; also, gender interacts with personal and task characteristics. Discusses educational implications of these results.…

Attempts to determine the relative difficulty of playing selected types of melodic pattern by ear; studies the effects of performance experience and instrument family on the ability to play by ear; and investigates the relationship between tonal aptitude and ability to play by ear. Presents results and questions for further research. (DSK)

Undergraduate psychology examinations from 48 schools were analyzed to determine the proportion of items at each level of Bloom's Taxonomy, item format, and test length. Analyses indicated significant relationships between item complexity and test length even when taking format into account. Use of higher items may be related to shorter tests,…

Suggests that English-as-a-Second-Language (ESL) teachers assess prospective textbooks by comparing real-life user's actual knowledge of the author's assumed student knowledge. Through examination of charts and page excerpts of two ESL grammar textbooks, demonstrates that access to the pedagogical knowledge demands sophisticated formal knowledge,…

Evaluation of the role of concreteness and familiarity in the development of proverb comprehension in 180 students in grades 5, 8, and 11 found that both concreteness and familiarity as well as student age, influenced comprehension. Results support the "metasemantic" and the "language experience" hypotheses of language comprehension development.…

A method is described for increasing residual degrees of freedom in a community experiment without substantially increasing cost or difficulty by dividing experimental subunits into batches. Theoretical advantages of batch sampling are described and illustrated with data from the Pawtucket Heart Health Program. (SLD)

Proposes a new technique for the evaluation of question difficulty. Suggests that question dispersion by multidimensional scaling models the question-response pattern required by test theory, but without the population density requirements of the traditional methods. Considers the effect on knowledge management functions, including library…

Off-campus students (n=173) and agriculture faculty (n=262) agreed on the rigor, effort, and cognitive outcomes of on-campus courses. Students believed off-campus courses required more effort; both said off-campus students contribute less to discussions. Students believed the rigor of on- and off-campus courses was equivalent; faculty felt…

Four experiments investigated the development of visuomotor control in sequential pointing in tasks varying in difficulty among 6- to 10-year-olds and adults. Comparisons across difficulty levels and ages suggest that motor development is not a uniform fine-tuning of stable strategies. Findings raise argument for stage characteristics of…

Examines one preschooler's conversation with author to determine what concepts educators consider "difficult" for this age group. Finds that concepts such as "infinity" and "negative numbers," typically avoided by primary educators, were brought into view in the task-based conversations. Argues that individual…
