This is part two of a two-part manual for teachers using SMSG text materials for grade 9 students whose mathematical talents are underdeveloped. The overall purpose for each of the chapters is described and the mathematical development detailed. Background information for key concepts, answers for all exercises in each chapter, and suggested test…

The application of the programmable calculator to evaluating complicated formulas is illustrated by considering the formula for finding the area of any triangle when only the lengths of the three sides are known. Other advantages of the programmable calculator are discussed such as freeing the student to explore more challenging problems and…

Because the staffing formula mandated by Virginia's State Council of Higher Education yielded unrealistically low numbers of library personnel for the larger institutions and for multi-campus community colleges, the Subcommittee on Staffing of the Library Advisory Committee was charged with developing a more suitable formula. This report contains…

One framework for reading instruction that focuses on the message suggests that all words can be classified as matter or relation references. This framework is applicable to the words and symbols used in mathematical symbolic sentences when they are defined as two or more names for numbers of sets joined together by a relation symbol. The use of…

Linear classification functions (LCFs) arise in a predictive discriminant analysis for the purpose of classifying experimental units into criterion groups. The relative contribution of the response variables to classification accuracy may be based on LCF-variable correlations for each group. It is proved that, if the raw response measures are…

This is a supplementary SMSG mathematics text for junior high school students. Key ideas emphasized are structure of arithmetic from an algebraic viewpoint, the real number system as a progressing development, and metric and non-metric relations in geometry. Chapter topics include sets, projective geometry, open and closed paths, finite…

A sample of 266 eleventh-grade students were used in this research project. The findings imply that particular emphasis should be placed on practice in formula derivation. Other activities related to verbal computational problem-solving ability should be reserved for home assignment. (MP)

Use of the calculator to create a series of iterations to approximate i to some desired degree of accuracy is illustrated with three problems on interest rates. (MNS)

Presented are two problems that can be solved using a computer simulation by students who have completed Algebra II. The distance and bisector formulas and the various forms of the equations of a circle and straight line are the topics. Computer program listings are included. (MNS)

Attention is called to the apparent widespread misunderstanding of algebraic notation by secondary school students, and how this may arise from some common approaches to teaching algebra to beginners is discussed. (MNS)

Many drugs are used up by the body at rates described in terms of exponential decay. Two simple exponential formulas are discussed. (MNS)

Discusses a formula for determining number of microfiche readers needed in public libraries based on a Los Angeles County Public Library study weighing library size, user population, and information disseminating activity. Data on number of microfiche readers available to public in randomly selected Canadian public libraries are presented.…

Plotting a polynomial over the range of real numbers when its derivative contains complex roots is discussed. The polynomials are graphed by calculating the minimums, maximums, and zeros of the function. (MNS)

Compares various methods of defining derived quantities, arguing for a definitional formula using base or fundamental units in a word equation, or symbol-equations with the symbols explained. Suggests that fundamental units be defined operationally or left regarded as intuitive as in the case of length and time. (JM)

Describes method of selecting document groups for automation developed by Advanced Document Management Systems staff at Westinghouse Water Reactor Divisions. Criteria for inclusion of document in database, survey questionnaire, a weighting formula to assign priorities (critical, frequency of retrieval, quality assurance, interdivisional use), and…
