Instructional strategies that will develop the concept of a fraction are presented. Fractions as counting numbers, measures, and subdivisions are included, with a combination of regions and number lines suggested as a teaching aid. (MNS)

Results from an English assessment of achievement on two geometric topics, line symmetry and angles, are reported. Contrasts in the patterns of responses to related items, and to the same items by pupils aged 11 or 15, are highlighted. (MNS)

Results of a study of sound system acquisition of five-year-old students of English-as-a-second-language show that first- and second-language learners exhibit similar but not identical simplification processes, and that evidence for a common developmental sequence in acquisition of consonant sounds was limited. (MSE)

The accuracy of data collected by Dutch geography students in a field study of commercial activities in a French city was monitored with data available from official lists. The causes of error, both in student work and official sources, and some lessons for future field work are examined. (Author/IS)

Results from testing long division with students from age 11 to Continuing Education were traced. A much higher percentage of wrong answers was given when there was an embedded zero in the answer. (MNS)

When asked to judge as correct or incorrect three categories of sentences (those with errors similar to their own patterns, those with common "baby errors," and correct sentences), four-year-olds made significantly fewer corrections of errors similar to their own, suggesting that children learn their own errors. (MSE)

The content of 228 college student's writing samples appears to be a main determiner of how many and what types of preposition errors will appear. These results indicate that preposition errors point to cognitive lags and complex, abstract writing tasks may be the appropriate treatment. (Author/PN)

Dialogue from an interview with a child about division basic facts is presented. The facts are considered by groups, and specific errors are noted. Finally, remediation ideas are given. (MNS)

Argues that children with limited English-speaking ability are often misdiagnosed as poor readers on formal and informal measures of reading ability. Offers suggestions for management of true miscues made in oral reading. (FL)

Reports that good elementary school readers corrected more miscues than did poor readers, that poor readers relied more on graphophonemics to make corrections than did good readers, and that there were small differences between both groups' use of semantics and syntax to make corrections except as material increased in difficulty. (FL)

Concludes that dialect speakers' miscues do not significantly influence their ability to comprehend print material when they are asked to read material at their instructional level. (FL)

Considers "unpacking" or "deconstructing" sentences (the reverse of sentence combining) an effective teaching technique that helps students to develop clear predication and eliminate their tendency to use vague, confusing nominalized verbs. (RL)

The ranking of acceptability accorded by 316 young native English-speaking and bilingual adults to the 11 most common morphological errors of nonnative speakers of English are correlated with the age, sex, linguistic sophistication, and bilingual status of the native speakers. (PMJ)

Four groups of children (N=80; C.A. 6.6. to 12.5; M.A. 7.9 to 14.7) were tested for ability to reproduce five-element two- and three-dimensional patterns. Significant interaction and main effects were found. Three-dimensional pattern performance increased with age; all ages performed well on two-dimensional patterns. (Author/DB)

Investigated group interaction and mathematical errors of 11th-grade students working individually and in four-person heterogeneous ability groups. Averaging over all types of errors, high-ability students did best in individual conditioning, low-ability students did best in group conditioning, and medium-ability students did equally well in both.…
