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)

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)

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)

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)

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)

Research on learner's beliefs are summarized in the areas of beliefs about mathematics as a discipline, beliefs about learning mathematics, beliefs about mathematics teaching, and beliefs about self within a social context in which mathematics teaching and learning are occurring. (PK)

This study surveyed 91 special education teachers to determine perceived mathematical needs of exceptional children, ways teachers assess skill deficits, and teachers' methods and backgrounds. The continuum of skills corresponded to the standard curriculum. (MNS)

Describes a research methodology known as the teaching experiment and details an example of a teaching experiment aimed at the development of a process-oriented algebra curriculum. Addresses other possible variations of the teaching experiment, emphasizing the cooperation of teachers and researchers. (TW)

The study investigated which addition facts children and preservice teachers view as being difficult, whether it is possible to determine facts which are difficult for all children, and whether children and adults agree on which facts are difficult. Results indicated that children and adults disagree about the difficulty of facts. (PK)

Presents the major findings identified by a commission that examined research issues in diagnostic and prescriptive mathematics. Addresses the diagnostic process with regard to curriculum, instruction, learners, teacher education, clinics, and the mathematics education community. (TW)

Describes the four competencies which are argued to be necessary for being an effective remedial mathematics teacher. Describes a training model which has been developed for preservice and inservice teachers based on these competencies. (PK)
