In this article we describe the initial investigations that we have conducted on student data collected from a web-based tutoring tool. We have used some data mining techniques such as association rule and symbolic data analysis, as well as traditional SQL queries to gain further insight on the students' learning and deduce information to improve…

The acquisition of case and gender marking on the definite and indefinite article was studied in a sample of 6 normally-hearing children and 9 children with cochlear implants. Longitudinal spontaneous speech data are used. Children were matched by MLU, with 4 MLU levels: 1.8, 2.8, 3.6, 4.8. Age ranges for normally-hearing children were 1;4 to 3;8…

This study examined the interaction between working memory and language comprehension in children with specific language impairment (SLI), focusing on the function of the central executive component and its interaction with the phonological loop (A. D. Baddeley, 1986) in complex working memory tasks. Thirteen children with SLI and 13 age-matched…

Converging evidence supports the hypothesis that the most common subtype of childhood speech sound disorder (SSD) of currently unknown origin is genetically transmitted. We report the first findings toward a set of diagnostic markers to differentiate this proposed etiological subtype (provisionally termed "speech delay-genetic") from other…

A multi-faceted Rasch measurement (MFRM) model was used to analyze a clinical skills assessment of 173 fourth-year medical students in a Midwestern medical school to investigate four types of rater errors: leniency, inconsistency, halo, and restriction of range. Each student performed six clinical tasks with six standardized patients (SPs), who…

This book provides a comprehensive collection of 66 teaching strategies and ideas to help overcome problems with number, each linked to a specific kind of error described in the related manual. Most of these strategies are classroom-ready and easily implemented. Some are notes for the teacher to read and then plan activities accordingly, and many…

A discussion of English-as-a-Second-Language (ESL) teaching focuses on the relationship of lexical items to the syntactic situations in which they may occur, and the importance of teaching this relationship to language learners. First, common errors made by ESL students that are attributable to lack of syntactic context knowledge are identified.…

This study analyzed the pronunciation of English interdental fricatives by two native speakers of Turkish, focusing on whether there was systematic variation of forms according to the kind of discourse and the surrounding phonemes. Subjects were two adult Turkish learners of English as a Second Language, both of whom had been in the United States…

Two studies were conducted at the Southeastern Louisiana University (SLU) to determine possible uses of errors and omissions on surveys of incoming and freshmen college students. The subjects of the first study were 1,927 individuals who had applied for admission to SLU and attended freshman orientation in the summer of 1989. Blanks and incorrect…

Argues that a computer-based programming tutor for novice programmers needs to take into account not only the types and frequency of bugs found in the programs, but the intentions and knowledge state of the programmer. A first version of such a program was developed on the basis of the bug types found in a number of pencil-and-paper studies with…

This report describes PROUST, a computer-based system for online analyses and understanding of PASCAL programs written by novice programmers, which takes as input a program and a non-algorithmic description of the program requirements and finds the most likely mapping between the requirements and the code. Both the theory and processing techniques…

In a test administered to Spanish-speaking students of English as a second language at the elementary and intermediate levels, the results indicated the subjects' reliance on the strategies of overgeneralization and transfer was qualitatively different. Implications of the results are discussed. (Author/RM)

A test administered to 73 adults learning English as a second language revealed a highly consistent order of relative difficulty in the use of eight functors across different language backgrounds. This study also confirmed earlier results indicating that children and adults use common strategies and process linguistic data similarly. (Author/KM)

This transcript of and guide to a two-cassette course designed to assist immigrants in erasure of their foreign accents can be used for either individual or group study. Narrative and taped demonstrations of American English that pinpoint typical phonological barriers and pronunciation difficulties are outlined. The author's own system of…

A study examined the patterns of error in the preterite and imperfect tenses in the written Spanish of native English-speaking college students. Errors found in the midterm examination were analyzed to determine whether they were due to incorrect tense, incorrect form of the tense, or both. It was predicted that many students would choose…
