In a study of very young children's pronunciation of nouns and verbs, ten children aged 20 to 25 months were exposed to experimental nouns and verbs, which had not yet been comprehended or produced by the children. Each of the objects and actions was given an experimental name based on phonemes in the children's speech. These objects and actions…

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…

Evidence on learning problems due to dyscalculia is surveyed. Definitions, factors responsible for dyscalculia, split-brain research and hemispheric roles, mathematics learning problems and personality, materials for instruction, and levels of knowing mathematics are among the topics discussed with an extensive list of references. (MNS)

Four informal assessment techniques to detect student mistakes in math, increase motivation, and improve achievement include the following: building models and generating word problems, thinking aloud, building mathematical sentences, and making mathematical sentences to answer questions in word problems. (DB)

The rule space model permits measurement of cognitive skill acquisition and error diagnosis. Further discussion introduces Bayesian hypothesis testing and bug distribution. An illustration involves an artificial intelligence approach to testing fractions and arithmetic. (Author/GDC)

Second and third graders from six Dutch elementary schools (N = 168) solved two sets of almost identical addition and subtraction sums at a two-week interval. Inconsistency in strategies, which characterized half the subjects, was related to unfamiliar sums and resulted in misinterpreted errors. (TJH)

Focuses on the learner's problems in producing the correct grammatical gender for a given noun in German. Discusses the complexity of gender assignment and the lengthy process of acquisition of gender. Examines error patterns made by English students of German. (Author/LMO)

Results from a British study on Strategies and Errors in Secondary Mathematics are considered. Students' views of algebra and their difficulties are summarized, with some suggestions for teachers. (MNS)

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)

Numerical inaccuracies, which occur in many ordinary computations, can create serious problems and render answers meaningless. Cancellation and accumulation errors are described, and suggestions for experimentation are discussed. (MNS)

Four different conceptions of error-making from a pedagogical perspective are developed. Using errors as springboards for learning is advocated, so that better understanding of content and of the nature of mathematics results. (MNS)

This is a report of an application of the interpretation of errors and springboards in a real-life situation. If and why we need to reduce fractions is considered. (MNS)

A common mistake in adding fractions involves the confusion betwen the concepts of fraction and ratio. A coherent system to operate with ratios is developed. (MNS)

Reports on the effectiveness of a theoretically based computer spelling program designed to help learning disabled students practice lists of words. The program employs a type of computer response called Imitation-Plus-Modeling. (AEA)

Describes a microcomputer-based system for diagnosing children's multiplication errors which incorporates the knowledge base of all known systematic multiplication errors, and utilizes a modular approach to cope with the program's complexity. Each module's function, how the programs interact, and the design of pupil-machine interaction are…
