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…

This research is aimed at diagnosing the problem-solving skill of elementary school children and subsequently improving their competence in early mathematics. To reach this goal, a computer assisted instruction (CAI) program on open sentences, incorporating knowledge about students' problem solving strategies and misconceptions, was constructed.…

Some aspects of foreign language classroom discourse are examined from a social theoretical perspective, and an attempt to raise the learners' awareness of the social reality created in interaction with other learners in the foreign language being taught is described. Through peer observation and the retrospective evaluation by the participants of…

This number of the journal contains the following articles: "A Language-and-Learning Framework for a Theory of Language Teaching" (Moira Chimombo); "Using Authentic Video Materials in the Language Classroom" (Kathleen Kitao); "An American Teacher in Kiev: Impressions of English Education in the U.S.S.R."

This study investigated the rates of successful mathematical performance and errors of information processing in third-grade children in California and continued an investigation of these factors in sixth-grade children. The objectives were to: (1) identify areas of mathematics in which the children had recognizable strengths and weaknesses, (2)…

This paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…

This study was designed to test the hypothesis that students who are given common errors matched with correct performance as part of their instruction in carrying out a procedure will perform better than students who are given only the correct performance. The task was the procedure for correcting color imbalances in color slides, and 56 college…

An index identifying factors leading to unusual response patterns by students, the modified caution index, was computed for the reading comprehension and study skills items of Booklet 5 from the 1979 National Assessment of Educational Progress (NAEP) reading achievement survey given to the 9-, 13- and 17-year-old samples. The analyses focused on…

Techniques to identify the degree to which a response pattern is unusual and the pattern's relationship to examinee background are presented. Sato's caution index and modified caution index use clusters of items for comparisons of observed performance outcomes and do not require the use of item response theory. Correlation between the indices was…

Different aspects of human-machine interaction are discussed in the five brief papers that comprise this report. The first paper, "Some Observations on Mental Models," discusses the role of a person's mental model in the interaction with systems. The second paper, "A Psychologist Views Human Processing: Human Errors and Other…

This study used the Montague-Riley Test to introduce a new scoring procedure that revealed errors in cognitive processes occurring at subcomponents of an electricity problem. The test, consisting of four parts with 36 open-ended problems each, was administered to 250 high school students. A computer program, ELTEST, was written applying a…
