It has been found that students gain much greater insight into routine calculations with business formulas when such work is viewed in the light of graphing concepts. Ten problems are presented that illustrate how three specific objectives in a unit on graphing in a business mathematics course have been met. (MP)

Provides examples of ways science teachers can use various forms of graphs to teach reading skills. (FL)

The two-hour learning activity described here is designed to interest students in graphing by having them use data about themselves. Students compete in physical and mental activities, then record and graph their scores. (SJL)

Presented are two computer programs which can be used to minimize the effort and time necessary to graph several individual functions. (TG)

Approaches to developing a good mathematics textbook for the junior high student are discussed, with the pitfalls and difficulties reviewed. Examples from new Polish textbooks are presented to illustrate possible solutions. (MP)

Presents a taxonomy of graphs, including lineal, quantitative, spatial, pictorial, hypothetical, and omitted graphs. Provides illustrations of each kind of graph and suggests that reading teachers take the responsibility for teaching graph reading and drawing skills. (MKM)

An alternative application of logarithms in the high school algebra curriculum that is not undermined by the existence and widespread availability of calculators is presented. The importance and use of linear relationships are underscored in the proposed lessons. (MP)

Four problems are presented and solutions using a calculator are illustrated. (MK)

Adapts a metaphor to draw attention to four aspects of the relationship between originator and user, and the communication medium: the problem of encoding information in graphic form, diagrams as tools for enquiry and thought, illustrations as aids to learning, and illustrations as aids to problem solving.

Distinguishes five main categories of special libraries in Singapore: those of private organizations, foreign governments, government departments, statutory boards, and regional organizations. Statistical data are provided for library holdings, professional staff employment, and subject profiles, and suggestions for improving various aspects of…

Graphing activities appropriate for grade levels K-8 are outlined and worksheets given. Topics involved include classifying, bar graphs, remainders from a series of divisions, and the greatest common factor of two numbers. (MP)

Presents graphs that can be used to illustrate the concepts of buffer capacity and acid-base titrations. (MLH)

Presents a study that introduces data logging using portable computers as part of an investigative approach to science. Working with control and experimental classes of 14- and 16-year-olds, results suggest that data logging can have an impact on graphing skills at age 14 which is not necessarily repeatable at age 16. (Author/AIM)

Describes a lesson that uses the graphing calculator to prompt the proof of the mean-value theorem. Students, through guided questioning, proposed the idea of using a difference function to find where a tangent line is parallel to a secant line. Through the use of graphing technology, students conjectured the essential fact that the constructed…

Describes computer or calculator-graphing technology to develop parametric representations which help students connect mathematical topics from algebra and trigonometry through algebraic, graphical, and numerical representations. Computer or calculator graphing utilities instantly transform algebraic expressions into visual and numerical displays…
