Research recurrently indicates that children who have difficulty with arithmetic often use systematic routines that yield wrong answers. Recent research has focused less on identifying the most common errors among groups of children and more on analyzing individual children's errors. This paper considers the source of systematic errors in…

This study attempts to determine whether the syntactic errors children make while learning a second language are due to native language interference or to developmental cognitive strategies, as has been found in first language acquisition. (Author)

The properties of four different tests of the treatment effect in experiments using linguistic materials are examined. (Author/RM)

Explores 96 preschool children's utilization of complementary and taxonomic relations under varying task demands. Results indicated that, as task demands increased, (1) complementary intrusions produced systematic error in the taxonomic condition and (2) performance decreased in both conditions. Complementary pairs were maintained at progressively…

Twenty-five infants were tested every two weeks on the AB Object Permanence Task, from the time they first reached for a hidden object until they were 12 months old. Results indicate that the AB provides an index of the ability to carry out an intention based on stored information despite a conflicting habitual tendency. (Author/RH)

The informal subtraction strategies that children develop are discussed in detail, with the role of the counting-down strategy described. Problems and remedies for difficulties caused by counting backward and the double count are also presented. (MNS)

This study examined the hypothesis that perceptual errors on a task requiring subjects to take different viewpoints could be explained in terms of response bias. Results were consistent with response bias hypothesis: making an egocentric error is different from behaving in an egocentric manner. (Author/SB)

The article reviews the development of mathematics error analysis as a means of diagnosing students' cognitive reasoning. Errors specific to addition, subtraction, multiplication, and division are described, and suggestions for remediation are provided. (CL)

This experiment involved 176 London children aged six and seven. Their levels of attainment on subtraction were quickly and accurately established by two questions. Then teaching programs were used to help them attain prerequisite skills. To symbolize too soon is a danger to be avoided. (MNS)

Several common errors reflecting difficulties in probabilistic reasoning are identified, relating to ambiguity, previous outcomes, sampling, unusual events, and estimating. Knowledge of these mistakes and interpretations may help mathematics teachers understand the thought processes of their students. (MNS)

Provides overview of significant facets of Error Factors (EFs)--promoters of underlying confusion in learning--discussing main types of EFs, sources of EFs in learning contexts, factors influencing frequency of EFs, use of tests and exercises, and effects of EFs and their mistreatment. Forty-seven sources are listed. (EJS)
