Research on the psychological processes involved in early school arithmetic has now accumulated sufficiently to make it possible to construct a coherent account of the changing nature of the child's understanding of number during the early school years. This monograph presents an account of how number concepts are extended and elaborated as a…

Findings of phase 1 of a study of the 1979-1980 Basic Educational Opportunity Grants validation, edits, and application processing system are presented. The study was designed to: assess the impact of the validation effort and processing system edits on the correct award of Basic Grants; and assess the characteristics of students most likely to…

An update to the Validation, Edits, and Application Processing and Error-Prone Model Report (Section 1, July 3, 1980) is presented. The objective is to present the most current data obtained from the June 1980 Basic Educational Opportunity Grant applicant and recipient files and to determine whether the findings reported in Section 1 of the July…

The study was undertaken to investigate the errors made by high and low achievers in a mathematics test administered to students in their second year of high school. The focus of the study was to determine whether any common error types existed within or between the two groups or whether there were error strategies which differed between the two…

This paper describes the development of a language arts test to assess the consistency of student response patterns and the feasibility of using the test to diagnose students' misconceptions. The studies were part of a project to develop computerized adaptive testing for the language arts with software to diagnose student errors. The…

A study examined aspects of the acquisition of spatialized morphology and syntax in American Sign Language (ASL) learned natively by deaf children of deaf parents. Children aged 2 to 8 were shown story books to elicit narratives, and the resulting use of verbs contained morphological forms not appearing in adult grammar. Analysis of the creative…

Research was conducted investigating properties of skill in learning, in the domain of elementary algebra. Thinking-aloud protocols indicate that early knowledge of the subjects studied was fragmentary, rather than involving systematically flawed procedures. Computational models, developed to simulate observed errors, focused on the role of…

A listing of substantial, known adult speech error corpora includes seven major corpora in English, 11 in languages other than English (German, Swedish, Dutch, Norwegian, Portuguese, Japanese, and Thai), information on seven collectors of smaller English samples, and two references for anecdotal samples, one in French and one in Welsh. Each major…

This issue contains abstracts and critical comments for 11 articles. Three articles focus on problem solving; the remainder concern understanding of the equals sign, mathematical structure, mathematical abilities, the role of language in tasks involving sets, sex differences in mathematical errors, subtraction, algorithms as schemes, and…

The nature and extent of misreporting by applicants for the Basic Educational Opportunity Grant program was investigated. Types of potential program abuse were assessed, along with the accuracy of income estimates that students make on Supplemental Basic Grant applications, which are the basis for determining a student's eligibility. Attention was…

The 1978-1979 pre-award institution validation process for the Basic Educational Opportunity Grant (BEOG) program was studied, based on applicant and grant recipient files as of the end of February 1979. The objective was to assess the impact of the validation process on the proper award of BEOGs, and to determine whether the criteria for…

This paper describes a classroom teaching experiment conducted in three fifth-grade mathematics classrooms with students of different achievement levels. Virtual fraction manipulative concept tutorials were used in three one-hour class sessions to investigate the learning characteristics afforded by these technology tools. The virtual fraction…

A review of literature on error correction shows a lack of agreement on the benefits of error correction in second language learning and confusion on which errors to correct and the approach to take to correction of both oral and written language. This monograph deals with these problems and provides examples of techniques in English, French,…

A progress report is presented of a study which applies a system of generative grammar to error analysis. The objective of the study was to reconstruct the grammar of students' interlanguage, using a systematic analysis of errors. (Interlanguage refers to the linguistic competence of a student who possesses a relatively systematic body of rules,…

This selective bibliography lists 14 books and 24 journal articles dealing with French-English contrastive studies. The entries range in date from 1954 to 1975 with the majority published since 1965. The books cited are mostly European or American publications and the articles appeared in well-known European or American pedagogical language…
