### Textbook

Texas Instruments 83 Plus™ Graphing Calculator and Manual

### Course Description

Introduction to application software appropriate for the teaching of secondary mathematics. The programs include spreadsheet, geometric modeling, and statistics modeling. Writing simple programs for graphing calculators to demonstrate and solve mathematical problems.

### Course Outcomes

1. Perform basic operations or a graphing calculator
2. Understand and create a flow chart
3. Understand and explain programming language components
4. Create programs to perform mathematical functions
5. Create programs to solve mathematical problems
6. Perform simple programming commands contained in spreadsheet software
7. Understand and perform geometric modeling using appropriate software
8. Understand and perform statistical modeling using appropriate software

### Evaluation

 A = Meeting all goals and objectives exceeding minimum standards with excellent of work. B = Meeting all goals and objectives exceeding minimum standards with very good quality of work. C = Meeting all goals and objectives at minimum standards with good quality of work. C- = Meeting most goals and objectives at minimum standards. D = Not meeting most goals and objectives at minimum standards with poor quality work. F = Meeting very few goals and objectives with extremely poor quality work.

#### Categories of assessments

 Participation 15% Assignments 15% Project 15% Two Tests 25% Final 30%

Scale: A ≥ 93%, A- ≥ 90%, B+ ≥ 87%, B ≥ 83%, B- ≥ 80%, C+ ≥ 77%, C ≥ 73%, C- ≥ 70%, D ≥ 60%, F<60%.

#### Tests

Tests will be equally weighted on-demand pencil and paper assessments of student knowledge based on class discussions, class work, and assignments. Tests can be retaken for a better grade. This test can only be retaken after the student has talked with the instructor. If you do worse on the retake, no change will occur in your grade. If you achieve a higher grade on the retake, that grade will replace the lower one. This is a no lose retake test! The FINAL will be comprehensive.

#### Assignments:

Assignments will be given during the semester for each section in the syllabus. We will talk about most of the problems on those assignments. Work and rework the problems until you have a solution. These problems are for your thinking and learning, and I will not "grade" the homework per se, but you will submit the homework one week after the conclusion of each chapter. We will discuss the homework in class to a limited extent (no more than 15 minutes), on an as needed basis.

Write three programs for the TI-83 Plus that will be appropriate for Secondary Mathematics.

#### Participation

CSUDH expects students, staff, faculty, and administrators to show mutual respect and to adhere to scholastic honesty in the pursuit of intellectual, social and personal advancement. As an institution, CSUDH deplores cheating, fraud, plagiarism and any other type of academic dishonesty. CSUDH reserves the right to initiate a series of disciplinary measures or sanctions to secures academic integrity as described in the CSUDH Catalog.

### Pagers and Cell Phones

Pagers and mobile phones must be turned off or operate in silent mode during class hours. Under no circumstances are you to take a call during class. If the call is important, step outside the room!

A grade of Incomplete (I) may be assigned if you are unable to complete a definable portion of the class due to unforeseen circumstances. The student is responsible for applying for an Incomplete by completing the appropriate form before the week of finals. A grade of U (unauthorized incomplete) will be assigned if you did not withdraw from the course and you did not finish the course requirements.
