This paper discusses variation in reasoning strategies among expert mathematicians, with a particular focus on the degree to which they use examples to reason about general conjectures. We first discuss literature on the use of examples in understanding and reasoning about abstract mathematics, relating this to a conceptualisation of syntactic and…

Little is known about the academic processing speed (i.e., rapid automatic naming and academic fluency) of children and adolescents with emotional and behavioral disorders (EBD) served in public school settings. A cross-sectional design was used to investigate the (a) percentage of K-12 students with EBD served in public school settings with…

Presents results from an Australian study examining whether children who use cognitive strategies in solving simple addition questions develop greater proficiency in addition than children who do not use such strategies. Describes the subjects, instruments, procedure, and instructional treatment. Concludes that the development of cognitive…

Fifty-nine children with varying amounts and types of day-care experience were followed over their first 2 or 3 years of public schooling. Schoolteachers rated aggressiveness of several types and in several situations and supplied information about managing the children, their use of conflict-avoiding strategies, and other associated skills and…

Two different methods of collecting information about student activity in the laboratory were compared using a series of videotape recordings. One method was based entirely on the systematic observation of student behavior (interaction analysis); the second method involved students describing their laboratory activities while watching excerpts…

Forty-four percent of teachers in public schools reported that there was more disruptive classroom behavior in their schools in 1986-87 than 5 years before. Almost one-third (29 percent) indicated that they had seriously considered leaving teaching because of student misbehavior; and on the average, teachers estimated that about 7 percent of the…

The purpose of this study of the Charlotte-Mecklenburg Chapter 1 Preschool Program was to document the program's effects and to make a start at determining whether the program prevents later school problems. It was hypothesized: (1) that former preschool program members would have significantly better language development than eligible students…

This study compared the effectiveness of microcomputer and workbook instruction on silent reading comprehension performance of mild mentally retarded and learning disabled 11- to 13-year-olds. Effectiveness was measured by percentage of correct responses to reading comprehension questions and by observing subjects' attention to task behavior. (MBR)

The paper describes a behavioral-ecological assessment system called AIMS (Assessment for Integration into Mainstream Settings) and presents the results of a comparative study of the responses of four Australian (N=179) and two U.S. (N=72) elementary teacher groups on two of the AIMS assessment instruments, the Social Behavior Standards Inventory…

Beginning in fall 1991, Napa Valley College (NVC), in California, switched from essentially mandatory placement of incoming students to an advisory, self-selection system, where students receive course recommendations based on assessment test results. In order to evaluate the validity of NVC's assessment procedures, a study was conducted of…

There were declines on achievement tests between 1972 and 1980. This study, the first part of A Study of High School Excellence, was designed to document changes in the achievement of high school seniors between 1972 and 1980, to identify the school and student factors related to these changes, and to examine the policy implications of the…

Observations were conducted to document the active academic responding and academic engagement rates of 122 elementary students (30 learning-disabled, 32 emotionally/behaviorally disturbed, 30 mildly mentally retarded, and 30 self-contained programs. Data were recorded in 10-second intervals for each student over an entire school day. During a…

This study demonstrated that, although standard instructional design revisions of a traditional textbook chapter had no effect on teacher attitudes toward adoption of the material, the revised version of the chapter significantly improved student performance. Teacher and student participants in the study were from the St. Petersburg…

To examine the hypotheses that differences exist between Indians and non-Indians in the nonverbal regulation of conversation and that these differences cause functional difficulties in classroom interaction, the study quantitatively examined differences in the nonverbal repertoires of students and teachers in an American Indian school system and a…
