Ten examples of when the sequences of key presses given in calculator instruction booklets are either inefficient or lead to an incorrect answer are given. (MNS)

Analyzes the omission, overgeneralization, and misuse errors in the compositions of first- through third-year university Spanish students, with major emphasis placed on the role errors play in the acquisition of Spanish as a second language. (EKN)

Examples of four interviews are presented to serve as sample evidence in support of more comprehensive diagnostic procedures in assessing reliably and validly the weaknessess and strengths of learners. The search for computational errors is seen to go beyond standard paper and pencil tests. (Author/MP)

Analyzes the overgeneralizations of bilingual children to determine whether the overgeneralizations of Spanish and English monolinguals would differ from those found in the speech samples of Spanish-English bilinguals and to reach a better understanding of speakers' preference for certain affixes and roots. (MES)

Different indices can be used to measure an individual's pattern of responses on an achievement test as usual or consistent with the norm. The relationships among eight of these indices are investigated for a math and reading test given to approximately 2,100 fourth-grade students. (Author/BW)

An investigation of the confusion resulting from reliance on visual perceptual teachers in the identification of dactylemes (handshapes) in the American Manual Alphabet (MA) is reported. A hierarchy of errors varying with subjects' degree of expertness in the MA is established. This can help manual communication teachers develop techniques for…

This is a preliminary report on research into computational errors made by six- and seven-year-olds. (Author/MK)

Attitudes toward and approaches to error in language learning depend on one's point of view: strictly linguistic, pedagogical, or that of the learner. This last approach is that "one learns by making mistakes," and from that perspective, there is no absolute definition of error, but only an operative one. (MSE)

Errors of misclassification and their effects on categorical data analysis are discussed. The chi-square test for equality of two proportions is examined in the context of errorful categorical data. The effects of such errors are illustrated. A correction procedure is developed and discussed. (Author/MH)
