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…

In this study, 35 students in two sections of a second remedial mathematics course for technical majors were given lectures with and without intentional errors. Achievement in the non-error group was higher, but evaluation scores for teachers making errors were higher. (MNS)

Common problems encountered in teaching Chinese that involve classical, intentional malapropisms (learned errors) are discussed. Three aspects unique to Chinese are addressed: (1) since Chinese writing is logographic, some malapropisms occur because of similar graphs; (2) since many expressions come from classical Chinese, and instruction in…

Notes that the basic elements of the English article system are best taught to foreign technical writing students over an extended period of time. Outlines a teaching method that emphasizes reducing errors that native English speakers perceive as wrong rather than teaching the nuances by which native writers fine tune their relationship with their…

Attention is called to the apparent widespread misunderstanding of algebraic notation by secondary school students, and how this may arise from some common approaches to teaching algebra to beginners is discussed. (MNS)

A study of the holistic evaluation of writing compared holistic rating and the rating for "conformity to correct prose" technique, a technique based on error counting, of five essays representing five ability levels. The essays were produced in a college English-as-a-Second-Language program. The two scoring methods produced the same ranking of…

Seven graduate students in a seminar on classroom computing received instruction in LOGO programming. Programming protocols were collected periodically and examined for errors and misconceptions; in-depth interviews were conducted in order to understand specific misconceptions better. As novice students transit from instruction to experience in…

The contributions of acceptance of misconceptions about mathematics, mathematical self-concept, and arithmetic skills to mathematics anxiety and to statistics course performance were studied in 92 adult students aged 18 to 57 with a median age of 27, (16 males and 76 females). Results showed that acceptance of misconceptions and mathematical…

A classroom exercise to help college students of economics conceptualize, create, and learn from graphs is described. The technique is illustrated with an exercise concerning the concept of supply and demand in consumer markets. Classroom time required for the activity is small, and students become adept at manipulating models without anxiety.…

A study compared subjective and objective methods of evaluating college students' second-language communicative competence as expressed in their writing. (MSE)

An overall schema of interpretation for programming instructors is given, so that the misconceptions students develop in programming can be determined more readily. Types of language-independent and -dependent bugs, how they can be identified, and how to help students overcome them are addressed. (MNS)

To help college teachers assist students in approaching reference materials to obtain citations, basic points that students should identify within citations are specified, and useful classroom techniques and materials are suggested. Common errors in search strategies are also noted. Some suggestions are made for selection of indexes for searching.…

One technique for teaching college-level report writing consists of an essay that students use as a model for their own writing. This model, in turn, contains guidelines for composing a short essay, from title and subheadings to sentence and paragraph structure, word selection, errors to avoid, and revision. (MSE)

The purpose of this study was to: (1) describe differences in performance by non-native learners of English, when writing in different genres; (2) determine communicative value of grammatical errors as judged by a panel of native speakers; and (3) demonstrate inconsistencies in native speaker judgment of error gravity. Subjects were 20…

It is important that teachers help students to realize that writing is not simply a product, or a means to an end, but an exploratory, cyclical process. Research has shown that skilled writers conceptualize the effect of their writing as a whole, as a generative process, whereas unskilled writers are distracted by surface-level features and are…
