# Better Understanding of Mathematical Concepts through the Graphing Calculator

### Course Introduction

Teachers need to make sure their students to truly understand mathematics and not simply view it as a set of rules that do not make sense (Darling-Hammond, 2008). Research shows that using the graphing calculator as a learning tool can help students better understand mathematics (Edwards, 1994; Smith, 1998; Grouws & Kristin, 2000; Ye, 2009). Thus, this course should be used as a professional development program for teachers who may not know how to use the graphing calculator as a teaching tool to help students better understand mathematical concepts.

**Course Purpose**: At the end of the course, participants will be able to demonstrate utilizing the graphing calculator to increase student understanding of mathematics.

**Required Materials**:

1) a TI-Nspire graphing calculator (numeric or CAS versions acceptable) with the latest operating system.

2) a computer with TI CAS Teacher Edition Software and Internet access.

**Prerequisites**:

1) have a basic understanding of how to use TI-nSpire and TI CAS Teacher Edition Software

2) know the Algebra curriculum.

3) have an understanding of how to create a lesson.

4) be willinging to learn

5) be open minded in terms of your ideas of mathematics instruction

### Unit 1: Understanding the Benefits of the Nspire in Mathematics Instruction

Objective: By the end of Unit 1, you should be able to explain and understand why utilizing the graphing calculator for mathematics instruction is beneficial for student understanding.

### Unit 2: Operating the TI-Nspire and TI CAS Teacher Edition Software

Objective: By the end of Unit 2, you should be able to operate the TI-Nspire and TI-CAS Teacher Edition Software.

### Unit 3: Locating Existing Concept Activities for the Nspire

Objective: By the end of Unit 3, you should be able to locate and alter existing graphing calculator concept activities to use in lessons.

### Unit 4: Creating Concept Activities for the Nspire

Objective: By the end of Unit 4, you should be able to create graphing calculator concept activities to use in lessons.
