Describes features of Bliss Bibliographic Classification (BC2) that make it thesaurus-compatible and a source for thesaurus compilers: facet analysis, terminology source, thesaural relationship source, and updating ease. Problems with using BC2 as a thesaurus source are also considered, and two thesauri based on BC2 are described. (MBR)

Demonstrates that hierarchical naming schemes--one with a single namespace and fixed root spread over all machines in a distributed system, and a second with total namespace composed of some aggregation of individual namespaces of each component system's filestores--can coexist in distributed computer systems. Combined system's design is…

The gifted underachiever is considered in terms of definition, placement options, myths of giftedness, and instructional approaches. The article describes the usefulness of such techniques as exploratory process activities, use of interest areas, and rule application and stresses the importance of modifying the regular curriculum. (Author/DB)

The position paper (1981) of the National Joint Committee on Learning Disabilities presents a revised definition of learning disabilities and identifies issues and concerns (such as the limitation to children and the exclusion clause) associated with the definition included in P.L. 94-142, the Education for All Handicapped Children Act. (DB)

Argues that previous definitions of work and heat are inappropriate. Presents new definitions that are formulated using experimental quantities, claiming that they apply equally well to reversible and irreversible processes. Indicates some of the problems with earlier definitions and applies the new definitions to the First Law of thermodynamics.…

Presents a brief theoretical statement on definition and then discusses a study of the development of definition in children aged 5 to 10. The development of definition is characterized as the gradual articulation of a conventional definitional form out of more general forms of ordinary oral discourse. (NCR)

Reviews the problems of classifying gaming techniques and suggests a heuristic approach as one solution. Definitions of simulation, models, role, and game and play are discussed to help develop a classification based on a technique called gaming simulation. (Author/LRW)

When discussing discipline, educators must separate trivial-but-annoying discipline problems from serious or criminal behavior and define vague terminology. The school's informal and formal curricula, instructional styles, and scheduling must also be examined to determine when the school itself is at fault. Carbondale (Illinois) Elementary…

State guidelines for 1981/82 and 1985/86 were compared to identify trends in definitions and methods used to diagnose learning disabilities (LD). The later guidelines tended to delineate specific achievement discrepancy criteria. However, major components of LD definitions were not altered and IQ cutoffs were not implemented. (Author/DB)

Confusion about the meaning of validity in quasi-experimental research can be addressed by carefully relabeling types of validity. Internal validity can more aptly be termed "local molar causal validity." More tentatively, the "principle of proximal similarity" can be substituted for the concept of external validity. (Author)

The paper on learning disability (LD) definition and subtypes considers the nature of the definition and differentiation problems, the importance of placing and keeping LD in perspective vis a vis other learning problems, and future development of a LD classification schema using dimensions of cause, severity, pervasiveness, and chronicity.…

Presents a new definition of outdoor education. Describes the different approaches to outdoor education advocated in adventure education and environmental education. Proposes that an integration of approaches can result in a functional outdoor education experience. (ML)

Discusses problems related to defining environmental education (EE), examining historical attempts to define EE and EE's forerunners and/or concurrent companions (including resource-use, progressive resource management, and population education). Indicates that although unanimity of agreement results from problems of communication and "turf…

The paper describes efforts in other countries in seven areas of gifted education: the nature and definition of giftedness, identification, curriculum development, mentor and other out-of-school programs, special classes and schools, counseling, and teacher education. Problem areas are identified, including rural populations and underachievement.…

Suggests job aids have motivational benefits and discusses three ways in which they positively affect motivation: increases worker's confidence of success and amount of effort they are willing to invest in attempting tasks; increases expectancy while decreasing amount of motivation needed; and reinforces task importance.
