The author suggests that slope be introduced as a topic independent of graphs, and that it be presented in a way that makes some sense of using a fraction to represent it. Many examples are included. (MNS)

This paper reports on a study that investigated the interpretation of media graphs developed by student teachers. The analyses of interviews indicate that cognitive, affective and contextual, aspects might constitute important components of the interpretation of graph such as those that we can find in print media. Particularly we discuss Critical…

A graphical representation is used to construct a line one centimetre in length. (MP)

An alternative approach is described for presenting the idea of the derivative through the use of chords of a graph. (MP)

Argues that the aggregate good is a powerful pedagogical device in economics. Uses a simple graphical analysis that demonstrates to the student the concept of an aggregate good, that preferences can indeed be collapsed from many goods to two. (DB)

An activity which stresses on identifying features of functions like the rate of change, intercepts, local and global behavior, zeros and asymptotes is designed to increase the level of understanding of the students and also to clear any doubts that they might have. The students are then asked to make a summary of what was discussed in the class,…

The objective of the research presented here was to study the influence of two types of instruction for using an argumentation diagram during pedagogical debates over the Internet. In particular, we studied how using an argumentation diagram as a medium of debate compared to using an argumentation diagram as a way of representing a debate. Two…

Activities described for using zucchini to teach measurement include: guessing, graphing, and measuring length and weight; comparing sizes and shapes; and puzzles. (MP)

Graphing is an integrative skill because you can use it whether you are teaching measurement or geometry or number theory or most any other topic. It is also important as a mode of communication which can simplify a large amount of information. Here are five steps for effective presentation of graphing to young students. (Author/RK)

Suggests some aspects of the school environment which can initiate graphing experiences as well as present some guidelines for graphing. (Author/RK)

Considering a fraction as directions for graphing a line through the origin of the x-y plane is suggested. Strengths and weaknesses of the idea are also discussed. (MNS)

This paper describes "The Migration Method," a new technique for graphing a quadratic function (one of the major foundations of undergraduate mathematics) and finding its zeroes. The method promotes a higher degree of conceptualization, reinforces the concept of symmetry, encourages mental visualization, and strengthens the ability to…

A rationale for considering the implications of future trends and anticipating the future,'' and specific techniques for teachers. (Editor/SP)
