In Pre-Calculus courses, students are taught the composition and combination of functions to model physical applications. However, when combining two or more functions into a single more complicated one, students may lose sight of the physical picture which they are attempting to model. A block diagram, or flow chart, in which each block…

The fields of mathematics, science, and engineering are replete with diagrams of many varieties. They range in nature from the Venn diagrams of symbolic logic to the Periodic Chart of the Elements; and from the fault trees of risk assessment to the flow charts used to describe laboratory procedures, industrial processes, and computer programs. All…

A problem from a course called "Introduction to Gambling" is described. A flowchart and a computer program are included. (MNS)

The study was designed to investigate: (1) the relative effectiveness of three techniques for teaching verbal problem solving to general education mathematics students in a junior college; and (2) the relationships between various student variables and problem-solving ability after treatment. Three classes (N=72) at Florida College were randomly…
