A limited set of behaviors of three-, four-, and five-year-old children were observed in a day-care program designed to permit the children a maximum of freedom for environmental encounters. The sample consists of 20 children with day-care experience dating back to infancy and a group of 20 children (a contrast group) without prior day-care…

This guidebook on minimum course content for beginning algebra covers graphing, the distance formula, slope, the slope-intercept form of the equation of a straight line, algebraic and graphic solutions to systems of equations, functions, and variation. Overall goals for the course are stated; performance objectives for each unit, a course outline,…

This booklet contains suggestions for developing six of the twenty topics recommended for students in Secondary Forms III and IV in the schools of Victoria, Australia. These suggestions are intended for students for whom the standard course is unsuitable because of subject time allotments, ability levels, or vocational or educational needs. The…

Equations or systems of equations can be associated with letters of the alphabet printed in the coordinate plane. Messages can be coded and decoded with a computer or by hand. (SD)

This discussion of the mathematical potential of classroom events gives many examples of incidents that can be used for learning about topics such as one-to-one correspondence, counting, sets, ordering, time, fractions, money, shape, estimation, measuring, volume, area, number operations, and graphs. (MP)

Discussed are present trends in library education in information science, as based on a survey of course offerings found in library school catalogs. The courses offered are divided into five basic categories, and new directions in library education for information science are discussed. Recommendations for improvement of curricula are included.…

Given a set of dichotomously scored items, ordering theory attempts to identify a hierarchy among those items. A graphic representation is presented for an empirically obtained hierarchy and a testing procedure to evaluate hypothesized hierarchical relationships. (Author/JKS)

Three biorhythm cycles affecting behavior are discussed and graphed by using basic mathematical operations along with simple graphing techniques. (JT)

Develops a graphical method for studying the parallel susceptibility of an antiferromagnetic material. (SL)

Meterological information is used to develop a mathematical function resembling the sine function. (JT)

One way in which a computer simulation can convince students of the validity of formulas for the density and distributive functions of the sum of two variables is described. Four computer program listings are included. (MNS)

Discusses aspects of the syntax and semantics of film, and presents a scenario for the use of film by intelligent computer assisted instruction (ICAI) systems. An outline of a representation language for educational films on videodisc is presented, and an appendix provides conceptual graphs that explain notations used in examples. (Author/LRW)

Describes an expected precision (EP) measure designed to predict document retrieval performance. Highlights include decision theoretic models; precision and recall as measures of system performance; EP graphs; relevance feedback; and computing the retrieval status value of a document for two models, the Binary Independent Model and the Two Poisson…

Reviews the Linked Systems project protocols in the Name Authority Distribution Application and describes the requirements they were designed to meet. A technical evaluation of the protocols in actual operation at OCLC is presented, and suggestions for improved performance are made. (Author/CLB)

A research design is described that can act as a guide for the investigation of student satisfaction. The design is easy to implement and the outcomes can be graphically represented. Evening MBA students were surveyed using a modified form of the College Student Satisfaction Questionnaire. (MLW)
