Analyzes error patterns of kindergartners' mental addition task. Eight weeks of computational practice affected the errors of unpracticed combinations on a retest. Seven of 10 children mastered previously unknown combinations involving zero by learning a relationship rather than the practice and memorization of individual facts. (Author/YP)

Studied were the misconceptions that preservice elementary teachers have about multiplication and division. Results indicated that they are influenced by the same primitive models as students; the most common errors made by both groups are quite similar. (MNS)

Proposes a schematic multidisciplinary model to help developers of intelligent computer-assisted instruction (ICAI) identify the types of required expertise and integrate them into a system. Highlights include domain types and expertise; knowledge acquisition; task analysis; knowledge representation; student modeling; diagnosis of learning needs;…

Assignment projects for high-achieving ninth graders were developed, and a comparative evaluation study indicated that they were effective. It bacame clear that teachers needed more practical support, so a diagnostic study was undertaken, leading to the establishment of a link between a categorization of student difficulties and a hierarchy of…

Why students have difficulty with a proof (such as Cantor's) is discussed, with the focus on proof by contradiction. Methods may fail due to the difficulty of the concept and lack of understanding of how students are thinking. (MNS)

Examines reading and spelling errors made by children learning Arabic within a developmental framework. Finds that errors in reading and spelling persisted throughout primary school, pointing to the difficulties involved in mastering the Arabic written language. Notes that misreadings involved mainly diacritics whereas misspellings were related to…

Studies the kinds of errors made by American learners of Russian, the reasons for these errors, change in error patterns, and resemblance between the errors of foreign and primary language learners. (42 references) (CK)

Noise in the form of random errors arising from choices is a common problem. Examined three different approaches for coping with noise. Found that reciprocity works, provided it is accompanied by generosity or contrition. Changing one's choice after a poor outcome was not seen as helpful. Other points are discussed. (RJM)

Explores the possibility that importance may regulate the magnitude of the false consensus effect. Analysis revealed a strong false consensus effect but no reliable relation between its magnitude and attitude importance. Results contradict assumptions that the false consensus effect arises from attitudes that directly or indirectly influence…

Reports on a study that examined spelling errors of keywords in a university library online catalog. Data are presented on distribution of errors by machine-readable catalog (MARC) field location, part of speech, origin of the bibliographic record, and error type. Commonly misspelled word roots and specific mistakes are listed. (12 references)…

Data from a transcript database of 12 children collected in 1-hour samples every month from 1;0 to 3;0 support the hypothesis that there should be strong differences in the frequency and types of errors between pronouns with suppletive nominatives and those without. The suppletive nominative forms "I" and "she" are blocked from overextension in a…

In 3 experiments, 1,598 Japanese college students were examined concerning the learning of facts in 2 content domains, baseball and music. Content knowledge facilitated fact learning only in the relevant domain; learning ability facilitated fact learning in both domains. Effects of content knowledge and learning ability were additive. (SLD)

A survey of experienced and new presidents in 32 various colleges revealed that making mistakes is important to learning on the job, including when and how to take action, and when not to. Presidents reported learning about working relationships, contextual differences, the human side of administrative action, and their own limitations.…

In contrast with younger children of the same reading age, reading-disabled (RD) children performed poorly when they were required to independently abstract grapheme-phoneme (g-p) rules and use them to pronounce pseudowords. Results suggest a phonologically based productive deficit which interferes with the learning of g-p rules. (RH)

Argues that English-as-a-Second-Language writing can have its own distinctive power and eloquence in spite of, and sometimes because of, its errors. Examines several different kinds of "poetic" nonnativisms, suggesting why they were created and why they may strike native speakers as especially expressive. (SR)
