Examines the role of sound in reading Japanese Script and evaluates arguments for semantic versus phonological identification to determine the relative importance of phonological processes in reading "kanji" and "kana." Implications for the teaching of kanji to learners of Japanese as a second language are explored. (Author/JL)

Studies applying the matching law of R. Herrnstein (1961) to college students' choice (n=55 and 31) to complete difficult problems suggest that interspersing problems requiring less time to complete into an assignment may increase rates of reinforcement that can alter students' choice behavior and improve their perceptions of assignments.

Studied the impact of changes in item difficulty on National Assessment of Educational Progress (NAEP) estimates over time through a Monte Carlo study that simulated the responses of 1990 NAEP mathematics respondents to 1990 and 1996 NAEP mathematics items. Results support the idea that these changes have not affected the NAEP trend line.…

Loglinear latent class models are used to detect differential item functioning (DIF). Likelihood ratio tests for assessing the presence of various types of DIF are described, and these methods are illustrated through the analysis of a "real world" data set. (TJH)

A review of research and theory on cognitive processes and their relationship to instructional technique since the early 1970s looks at the contributions of schema theory and artificial intelligence and their instructional implications, including cognitive load theory, worked examples for learning problem solving, and physical vs. mental…

The study of 21 teacher-child dyads showed that teachers of children (aged 2-8) with severe handicaps adjusted the complexity of their linguistic requests based on the child's communication level and modulated their requests based on children's responses. Teachers' adjustment of language structure was not as closely attuned to children's…

The effect of large, within-examinee item difficulty variability on estimates of the proportion of consistent classification of examinees into mastery categories was studied over 2 test administrations for 100 simulated examinees. The proportion of consistent classifications was adequately estimated using the technique proposed by M. Subkoviak…

Presents a readability formula suitable for passages from 40 to 99 words (provided they contain at least 3 sentences). (RS)

Potential benefits of using item response theory in test construction are evaluated using the experience and evidence accumulated during nine years of using a three-parameter model in the development of major achievement batteries. Topics addressed include error of measurement, test equating, item bias, and item difficulty. (TJH)

Examines the relative importance of vocabulary difficulty and prior knowledge on comprehension of narrative passages. Finds that knowledge-based preinstruction can significantly improve comprehension of a text dealing with an unfamiliar topic, but cannot compensate for difficult text vocabulary. (RS)

An investigation analyzed difficulty and discrimination statistics for 91 multiple-choice tests written by 46 business administration instructors and administered to 7,511 students. A large percentage of the tests failed the difficulty and discrimination standards proposed by several testing experts, implying that teachers need more preparation in…

Preschoolers presented with a difficult match-to-sample task requiring task analysis performed successfully when taught to overtly ask themselves questions about the salient features of each display and then answer the questions. Most subjects performed poorly when told not to use the self-questions and answers, but performed well again when…

This response to Brainerd and Reyna's paper (in this issue) argues that the common resources hypothesis can be applied to a wider range of phenomena than can the output-interference hypothesis. Presents results of a dual-task experiment under bidirectional deficits. Concludes that dual-task studies do not provide critical tests of the resources…

Three studies examined the hypotheses that: (1) codability and not extent of distance determines difficulty; (2) critical features and not whole objects are coded; and (3) implicit perceptual axes provide a frame of reference for coding the display. Results supporting these hypotheses are discussed in terms of a description of spatial…

Talkers vary widely in the ease or difficulty with which they can be speechread. Examined are variables contributing to visual intelligibility, comparisons with auditory intelligibility, the range of talker differences, characteristics accounting for these differences (facial cues, extrafacial gestures, rate, and rhythm), and implications for…
