The goal of this study was to find a way to quantify three criteria of representational quality, described by Greeno, so that it would be possible to examine statistically the relationship between representational quality and other variables related to problem solution. The sample consisted of 18 college students, 84 percent of whom had…

This document contains 15 research papers presented at the Fourth and Fifth Annual Conferences of the Research Council for Diagnostic and Prescriptive Mathematics. The papers are organized into four sections. In part I, four position papers by Romberg, Engelhardt, Ashlock, and Heddens reflect research ideas which underlie the Council. Part II…

The use of error pattern analysis can reduce the time and money spent on editing and correcting manuscripts. What is required is noting, classifying, and keeping a frequency count of errors. First an editor should take a typical page of writing and circle each error. After the editor has done a sufficiently large number of pages to identify an…

A study was conducted to explore the generality of reconstructive processes of memory for social information. Sixty college students divided evenly into six experimental and control groups were asked to read one of two versions of a story: one in which a couple happily agreed not to have children, the other in which the man's desire to remain…

There are two types of errors made in feeling-of-knowing (FOK) studies: a commission error occurs when a subject answers a question incorrectly, and an omission error occurs when a subject fails to provide an answer for a given question. A subject makes a commission error if he or she responds to the following question, "In which city does…

A study of the processing of morphophonology by native speakers and second language learners focused on the processing of the Japanese potential suffix. The subjects were 13 Japanese adults (mean age 27.1) and 13 advanced learners of Japanese as a second language (mean age 26.6). The production of the potential inflection by the two subject groups…

A study examined the information processing construct of the speech rating error paradigm. Specifically, it tested the hypotheses that (1) attitude valence and dogmatism would interact in such a way that low dogmatic raters would show a positive trait error on the content traits material and analysis; (2) low dogmatic raters would evaluate a…

In early computer assisted instruction (CAI), negative feedback often insulted students and/or provided no useful knowledge. In classroom settings, teachers use the following approaches in dealing with students' wrong answers: (1) ask the question again, louder and slower; (2) ask the question again, using different words; (3) back up and reteach…

Report of a study which examined the English proficiency of 22 Arabic-speaking students enrolled in a low intermediate intensive English course at the American University of Beirut. (Author)

An investigation which develops a method for the automatic collection of meaningful statistical information about the causes of program resubmittal in a batch-processing environment. (Author)

This study involved the extensive testing and interviewing of 102 primary grade pupils, representing a sampling from diverse school environments, to study the capabilities and difficulties evidenced by primary-grade pupils in solving open addition and subtraction sentences. Phase 1 of the study identified the specific incorrect procedures commonly…

A discussion of language judgments, particularly negative judgments of nonstandard variations of English, and the "errors" of speakers of English as a second language. (RM)

Investigated memory span and memory scanning in both auditory and visual modalities of 24 good and poor, 10-year-old readers. The major finding was that short-term memory function deteriorated over time in the poor reading group. (Author/LLK)

In the methods and approaches developed for estimating the operating characteristics of the discrete item responses, the maximum likelihood estimate of the examinee based upon the "Old Test" has an important role. When Old Test does not provide a sufficient amount of test information for the upper and lower part of the ability interval,…
