A typology of time-related concepts is put forth as a step toward the building of comprehensive theory in aging. The concepts derive from statistics (age, cohort, period effects), the theoretical writings of Sorokin (life course role sequences, durations and rates), the writings of Riley (on the synchronization of life course socialization and…

A MODEL OF HIERARCHICAL GROUPING IS APPLIED TO 24 INSTITUTIONS OF HIGHER EDUCATION. THE GROUPING IS A FUNCTION OF DIFFERENCES AMONG THE INSTITUTIONS' CHARACTERISTICS. THE THREE HIERARCHICAL GROUPINGS SHOWN ARE BASED ON (1) 10 USOE CATEGORIES OF INSTITUTIONAL CHARACTERISTICS, (2) 14 INPUT AND ORIENTATION VARIABLES, AND (3) 36 COLLEGE ENVIRONMENT…

A comparative evaluation involving two instructional programs is given, although the approach can easily serve to compare more than two programs. The steps involved in conducting a program fair evaluation of two instructional programs are: (1) Identify objectives (a) common to both programs, (b) unique to one program, and (c) unique to the other…

This paper proposes that instruction consists of four relatively independent facets: learner aptitudes, content structure, delivery systems, and instructional strategies. The purpose of this paper is to develop a taxonomic vocabulary and a model for portraying instructional strategies. Instructional strategies are defined as sequences of two or…

Compared five distinct classes of models of how people judge the relative sizes of named objects. Four basic experiments were all concerned with the amount of time necessary to decide which of two named things is larger. (Editor/RK)

The "property-set model" is proposed for concept learning and subsequent recognition and classification of old and new exemplars. In an experimental evaluation of alternative models, the property-set model was the best predictor of both recognition and classification performance. (Author/RM)

Identifies five institutional forms of library consortia, one of which is local consortia or proximal networks, and discusses issues that apply to local library consortia. Highlights include redefinition of the library role, appropriate technology, bibliographic control, direct access, governance, and financing. (10 references) (CLB)

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two.

An inductive concept-identification model of expository text processing, consonant with current theories of macrostructure development, is proposed as part of a reading comprehension instruction model. An evaluation study with fourth and sixth graders is described. Results are interpreted as supporting the model. (Author/BS)

Determines patterns of differential human development in a longitudinal study of 417 male and 358 female college students ages 18 to 30. Findings suggest individuality in development is associated with significant qualitative individual differences that are best described on a cross-time basis. (BJD)

Reviews retirement and preretirement programs using a comprehensive framework that reveals four distinct models: planning, counseling, adult education, and the human potential model. The human potential model integrates the effective features of existing programs with a positive view of retirement and a focus on the retirement transition period.…

Noting that current research on childrens mathematical development does not adequately detail how toddlers represent small numbers and the role that number words play in the development of number understanding, this study used a combination of methods to examine mathematical development in one toddler. Underlying the study was an Integrated Model…

This paper explores the roles students play in support of technology in elementary classrooms. In this ethnographic study, new models for support were developed by examining support for technology and the use of technology in three third and fourth grade classes. Data were collected through teacher interviews, informal conversations, observations…
