How laser videodisc technology can be used to improve mathematics instruction is described, with note of the development of a videodisc curriculum on mastering fractions. Relevant research is reviewed, as well as how teachers can use the technology. The instructional design is described, and field-testing and revision reported. (MNS)

Describes the Math, Science, and Computer Camp for girls ages 8-12. Includes vignettes that illustrate worthwhile mathematical tasks in which girls engage that expand their notion of mathematics. (MKR)

Reviews visualization research concerning the objects of visualization, the visualization process, and visualization in educational situations. Teaching procedures, the role of material and the social environment, and how the individual interacts with that environment are described. (YP)

Presents a first-semester course in mathematics for 6-year-old children by formulating certain general requirements for the curriculum and the instructional methods with the aim of leading children to form their initial mathematical concepts. (ASK)

Differences in the meaning of the terms "learning" and "achievement" are discussed, with implications for appraisal, placement, curriculum, and instruction. Visual discrimination learning, paired associate learning, adapting to learning, and learning to learn are illustrated with references to learning disabled students. (MNS)

Two authors introduce the topic of visualization in mathematics education. Fourteen articles are briefly described. (YP)

An overview is provided of the curriculum and instructional practices in general and for handicapped learners. Diagnostic teaching and other features of good instruction are reviewed. (MNS)

Investigated are three misconceptions of probability and the differential effect of two activity-based instructional units. Response categories (law of averages, law of small numbers, and availability) are identified. Treatment differences (evaluation or no evaluation) appear to influence subjects' interpretations of the information. (YP)

Introduces an introductory module for analysis. Describes stock of basic functions and their graphs as part one and three methods as part two: transformations of simple graphs, the sum of stock functions, and upper and lower bounds. (YP)

Ways in which children think of 10 are considered first. Then a study with 14 second graders is reported; students were placed at three levels with respect to their addition and subtraction concepts. Findings are detailed, along with implications for instruction. (MNS)

Describes a study designed to investigate the relationship between students' learning of the standard double-digit addition algorithm and basic fact mastery or numeration concepts. Results suggest basic fact mastery and knowledge of numeration concepts may not be as necessary as previously assumed to learning multidigit addition. (PK)

Some of the major curriculum and instructional problems that precipitate failure among learning disabled adolescents are discussed. A variety of intervention strategies to increase success are then presented. (MNS)

Literature on the topic of mathematics in special education is reviewed, with perspectives of authors from different countries. Issues and emergent trends in assessment and in curriculum and instruction are identified, after changes in policy and legislation and in content and methodology are discussed. (MNS)

Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)

Reports on a study designed to document that learning-disabled (LD) students make errors in estimating the passage of short time durations, and to determine if LD students were different than nondisabled in time estimation. Non-LD and LD students differed significantly in estimations of 15-second intervals, but not 3-second intervals. (PK)
