The Significance of Recursion Using the TI-84 Sequence Editor
Domenick, Anthony
Online Submission
Patterns are a ubiquitous phenomenon. They exist in nature's plant species emerging as a complete order from truncated matter. Patterns are also present in the fine arts where the aesthetic properties of form exist and conjugate through paintings and sculptures. Mathematical patterns, the focus of this position paper, dominate financial scenarios, growth and decay problems, as well as population rates. These topics can be articulated through the language of recursion where a present numerical value occurs in the sequential context of prior ones. Many college students have little or no knowledge of this recursion concept, and traditional analytic pedagogy is often characterized by tedium. The TI-84's designated sequence mode is modeled and implemented here as a paragon for students to define, investigate and visually perceive recursively defined problem solving tasks in terms of the natural value, n. The sequence mode structurally delineates the recursion function by translating present and antecedent iterations associated with the following conceptions: (1) a computational sequence; (2) a financial scenario; and (3) a medication problem. These three tasks are conveyed by applying n as an independent variable, a table of integer or discrete outcome values, and a graphic representation of a disconnected set of points. The TI-84 sequence graphing mode edifies the cognition of advanced algebraic topics for students.
