Experiment designed to test efficacy of techniques of comprehensive error correction on combined grammatical and orthographic correctness of compositions written by intermediate-level college students studying German found writing skill development favorably affected by appropriate techniques. They are: systematic scoring of compositions;…

Examines students' amusing responses to essay test questions, while maintaining that such responses can still give a teacher a better indication of what students are learning in the classroom than can objective tests. (HTH)

Discusses two types of student writing problems: error characteristics (spelling, pronoun usage, subject-verb agreement, run-on sentences, and capitalization) and nonerror characteristics (density of ideas, variety of referents, and variety of expression). Suggests ways to diagnose and correct them. (HTH)

A model which gives maximum likelihood estimates of measurement error within the context of a simplex model for practice effects is presented. The appropriateness of the model is tested for five traits, and error estimates are compared to the classical formula estimates. (Author/JKS)

A modified viewer rotation procedure was used to contrast two possible explanations of spatial egocentrism in spatial perspective tasks. Subjects were 60 children in first, third, and fifth grades. (MP)

Explored the relationship among conceptual tempo, age, sex, and performance of preschool children on the visual association subtest of the Illinois Test of Psycholinguistic Abilities. (Author/DB)

Ten dyslexic boys and 10 matched controls were asked to draw a person and write a composition. The two groups are compared on time spent on tasks, number of words written, and proportions of spelling and grammatical errors. (SJL)

Proposes an error gravity/distribution factor to give a mathematically consistent evaluation method to error analysis. Such an approach assumes that "seriousness" of error is related to frequency of output and not to notions of degree of communicative difficulty. Distribution of error type is also taken into account. (PJM)

The type and frequency of a variety of clerical errors were investigated in protocols from the 1949 and 1974 editions of the WISC. Potential consequences of such errors and a discussion of ways to lower the rate are presented. (Author)

Diagnostic teaching is described and discussed. Different types of errors are explained and examples of errors and their possible diagnoses are given. (MK)

A study to determine if "random" or "careless" errors in multiplication made by individual students take on discernible patterns is described. Implications for teaching are discussed. (MK)

This article, a reprint from 1930, offers an interesting perspective on the importance of diagnostic and prescriptive teaching as well as the role of drill and the use of objectives in mathematics. (Author/MK)

An exploratory investigation of various incorrect solution procedures used by students attempting to solve a variety of forms of open sentences is reported. The study identifies specific incorrect strategies, indicates their relative frequency of occurrence, and attempts to offer some explanation for certain of the incorrect procedures used. (MK)

Examined computational errors made by educable mentally retarded students on the arithmetic subtest of the Wide Range Achievement Test. Retarded students had a lower percent of grouping and inappropriate inversion errors and a higher percent of incorrect operation errors than regular students had in Engelhardt's study. (Author)

An approach to error identification in swimming strokes is presented based on principles of hydrodynamics and human movement and their application in swimming, systematic observation, and recognition of inefficient movement patterns followed by correction measures. (JMF)
