Modeling and Data Analysis (MODEL)
Purpose:
The T^{3} MODEL Institute is a weeklong professional development program for secondary mathematics teachers who have recently taught Algebra 2 or Precalculus. The institute will focus on data analysis and mathematical modeling. Institute participants will explore ways to incorporate data analysis and mathematical modeling into secondary mathematics classes and to use these themes to motivate the study of functions, trigonometry, and matrices. Participants will take part in handson activities that reinforce effective classroom use of technology. The goal of the program is to instruct teachers in new and innovative ways to effectively teach contemporary mathematics using technology in the spirit of NCTM's Curriculum and Evaluation Standards for School Mathematics (NCTM 1989) and Professional Teaching Standards (NCTM 1991).
Objectives:
The objectives of the T^{3} MODEL Institute are:
 To provide opportunities for teachers to experience an exploration/investigation mode of learning secondary mathematics so that they can be better prepared to incorporate these methods into their own teaching.
 To study techniques of data analysis and the use of data analysis as motivation for the study of other topics.
 To use techniques of mathematical modeling to solve real world problems, particularly those that are extended and might incorporate many mathematical ideas in their solution.
 To develop teachers' familiarity and facility with the graphing calculator.
 To help teachers find effective ways to use the graphing calculator to improve the teaching and learning of mathematics.
 To share ideas regarding assessment techniques.
Targeted Audience:
Participants in the T^{3} MODEL Institute should be inservice secondary mathematics teachers in grades 9 through 12 who have recent experience teaching Algebra 2 or Precalculus. Participants should be interested in using data analysis and mathematics modeling to motivate the study of secondary mathematics.
