Presents a collection of examples of familiar erroneous grammatical constructions in a scientific context, and provides suggestions for improved sentence structure. (WRM)

During the 1975-76 academic year student response data were saved for a group of 17 freshman music majors as they worked through 15 units of harmonic dictation exercises delivered on the University of Delaware's Graded Units for Interactive Dictation Operation (GUIDO) system. Analysis of the student data base led to the identification of seven…

Reports a class exercise which requires students to recalculate the Chi-squares, t-tests, and one-way ANOVAs found in published psychological research articles. Describes students' reaction to the exercise and provides data on the 13% error rate they discovered. (Author/JDH)

Two factors, language difficulty and option set convergence, were experimentally manipulated and their effects on item difficulty assessed. Option convergence was found to have a significant effect on item difficulty while the effect of language difficulty was not significant. (Author/BW)

Examines the sometimes puzzling behavior of writing teachers as they look for errors in language usage. Questions whether many of these teachers would notice the occurrence of certain features they call errors if they were not searching for errors in the first place. (RL)

The author discusses the use of calculators in calculus classes and difficulties caused by roundoff errors. References for advanced follow-up topics are given. (Author/MK)

Discussed are the mathematical methods for detecting a variety of common error patterns within the bar-coded identification numbers utilized in conjunction with scanning devices. Schemes for the use of check digits are examined that ensure conditions for detecting errors of specific types, including single digit error, transposition error, twin…

Two studies focused on aspects of the rating process in performance assessment. The first, which involved 15 raters and about 400 medical students, made the "committee" facet of raters working in groups explicit, and the second, which involved about 200 medical students and four raters, made the "rating-occasion" facet…

The Sato Caution Index takes into account the number and difficulty of items gotten wrong by a student within his or her ability, as well as the number and difficulty of items gotten right beyond his or her ability. Sato subtracts the two components to define a single Caution Index. In this study, the components are kept separate, defining a…

Two experiments investigated the effectiveness of reading backwards as a proofreading technique. Experiment 1 examined the general usefulness of backwards vs. forwards proofreading strategies and the effects of these strategies for two types of typographical errors: misspellings and contextual errors. Subjects, 36 undergraduate students at a…

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 survey of how 17 recent experimental psychology textbooks treated the subject of random assignment of subjects to groups for purposes of experimentation is discussed. Findings indicate that the textbooks generally gave favorable coverage to the practice. Further research might improve this simplistic understanding. (Author/DB)
