This paper models the educational process by a system of simultaneous equations. The endogenous variables (educational outputs) are a pupil's achievement, participation in a college preparatory program, need for achievement (aspirations), demonstrated motivation (effort), expectations, self-esteem, belief in his ability to control his environment…

The guide, intended as a model for teachers who will develop their own arithmetic curricular materials, introduces concepts sequentially from simple to complex and continues them from one level to the next at increasingly more difficult and abstract levels. The program is arbitrarily cut into four levels to correspond to school divisions: primary…

These proceedings include four articles intended to familiarize librarians with many facets of operations research and how they might be applied to their institutions. The first paper provides a brief definition of operations research. The second presentation, by Ralph Shoffner, relates, in the form of concrete examples, the questions one asks…

This study attempts to determine whether the pattern of human abilities varies or remains constant over a range of ability levels. Scores on 12 aptitude and achievement tests for 11,743 subjects, subdivided into four groups according to intelligence and socioeconomic status, were used. A technique, developed by Joreskog, for simultaneously factor…

The document contents divide into (1) the basic flow model of an educational system and its application to the secondary school system of Ontario and (2) a group of interrelated submodels that describe the entrance to higher education in considerably finer detail. In the first section, the principal variable of the model--the transition…

The philosophical underpinning of the purposes of the community college, an examination of the basis for state financial support from a philosophical viewpoint, and an analysis of the ways in which the various states have implemented that philosophy in financial support programs are the central focus of this report. The four current patterns of…

Considers several aspects of quantitative relationships involved in learning physics. Includes discussions of proportionality, various kinds of equality, and the need for generality. Argues that clear distinctions are necessary if the physics curriculum is to be examined with regard to pupil outcomes. (TW)

It is suggested that elementary school students find rational numbers troublesome because some teachers have an inadequate understanding of rational number concepts and poor facility with rational numbers skills. How to help them overcome difficulties, develop concepts, and know what topics to emphasize are discussed. (MNS)

Discussion of possible applications of the microsimulation approach to analysis of population policy proposes compulsory sterilization policy for all of India. Topics covered include India's population problem, methods for generating a distribution of couples to be sterilized, model validation, data utilized, data analysis, program limitations,…

"EFF HOT (Highlights on Teaching Topics) Topics" is a publication of the EFF (Equipped for the Future) Center for Training and Technical Assistance. Each issue concentrates on a specific topic, highlighting examples of actual practice and offering strategies and tools for using EFF in the classroom. In this issue, "HOT Topics" focuses on the…

Presents a model using 1973 North Carolina data which shows that government, private nonprofit, and for-profit producers of child day-care services serve different markets. Estimates market demand for each center type, with different responses to demand elements such as income and labor force opportunities, and discusses implications for public…

Presents five computer programs: (1) Accurate Numerical Solutions of the One-Dimensional Schrodinger Equation; (2) NMR Simulation and Interactive Drill/Interpretation; (3) A Simple Computer Program for the Calculation of 13C-NMR Chemical Shifts; (4) Constants of 1:1 Complexes from NMR or Spectrophotometric Measurements; and (5) Saturation…

Discussed is the process of translating situations involving changing quantities into mathematical relationships. This process, called dynamical modeling, allows students to learn new mathematics while sharpening their algebraic skills. A description of dynamical systems, problem-solving methods, a graphical analysis, and available classroom…

Presents activities for the K-2, 2-5, 5-6, and 5-8 levels that require students to analyze information graphically. Asks the students to discuss, describe, read, and write about the graphs and the information they contain. Supplies accompanying worksheets. (MDH)

The effect of indebtedness (undergraduate loan burden) after college graduation on the decision to pursue a graduate degree was studied for 899 individuals from the High School and Beyond study. Level of undergraduate debt was not a significant choice determinant. Some limitations of the methodology are discussed. (SLD)
