The purpose of this research is to evaluate the effectiveness of the area (homogeneous) scales of the Navy Vocational Interest Inventory (NVII) as predictors of Class "A" school achievement and as measures of rating differentiation by comparing specific occupational scales with more general interest measures--the NVII area scales. The…

This report presents projections of school enrollment by age, sex, and grade level to the year 2000, taking into account the latest population projections prepared by the U.S. Bureau of the Census. The figures apply to fall enrollments of the civilian noninstitutional population 5 to 34 years old in elementary school, high school, and college. The…

Examines two traditional approaches to the measurement of library service--the gathering of circulation and reference statistics--and relates them in a statistical model in an attempt to define real standards against which a library's activity can be compared. Graphs comparing reference and circulation statistics are included. (Author/JD)

This survey of the use of computer assisted instruction in schools for the deaf identified 34 systems with a total of 408 terminals, predominantly in elementary and secondary schools for the deaf; 28 of these computer systems are strictly used for CAI. (Author/JEG)

An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)

Some problems and classroom problem-solving settings presented in a mathematics methods course for elementary teachers are described and some results of student's involvement in the program are illustrated. (MN)

The students in a low-ability first-year classroom of a secondary school use a questionnaire and punched cards to collect and organize data about their classmates. The first five minutes and the first four minutes after the first quarter of an hour of the resulting class discussion are included. (MN)

Three activities are provided for introducing career education into the mathematics classroom as well as the rationale for doing so. (JT)

This reexamination of earlier forecasts and statistics related to research library growth--Purdue studies first published in 1965, data and forecasts from Fremont Rider's 1944 book--shows mixed results for evidence of continuing rapid growth of collections and acquisition expenditures and marked decline in acquisition rates.

Explains a study that proposed and tested how graphical representations influence what is learned and recalled from text. Results highlighted the importance of graph-focusing strategies for text learning and support the creative use of interactive computer presentation. (ML)

There are many problems that can be translated into the language of graph theory. Such a problem, discussed in this article is to show that in any group of two or more people, there are at least two people who have the same number of acquaintances in the group. (PK)

This activity exposes beginning algebra students to the concepts of slope and intercept. Four worksheets pertain to the "electrician problem." (MNS)

Discusses the uses of thermistors in teaching electronics and semiconductors. Describes how to experimentally measure and graph the characteristics of a thermistor. Suggests one possible approach to understand the shapes of the characteristics. (CW)

Although single-subject research techniques are valuable to counselors, analyzing change by graphs alone is open to major sources of error. Discusses these sources and explores the issues of serial dependency, unreliability of graphs, interjudge disagreement on graphed data, and the use of time-series statistics with relevance to the counselor in…

An intuitive approach to exponential functions is described. Microcomputers are used to aid discovery of derivatives. (MNS)
