Modeling in Algebra for Teachers

Course Time/Location: Mondays & Wednesdays 3:00 pm – 4:25 pm, NOC 207 (3 semester hours)

Required Materials:
• Activity packet will be prepared for student purchase.
• A TI-83 or TI-84 graphing calculator is required.

Description: This course is designed for K-8 pre-service teachers and focuses on variables, expressions, equations, inequalities, systems of equations, matrices, and linear, non-linear, and inverse functions. Emphasis is on problem solving, active learning, appropriate communication, substantive connections, technology utilization, and multiple representations of algebraic structures. This course may not be used to fulfill the academic concentration requirement for mathematics or secondary mathematics education students.

Prerequisite: Grade of C or above in MATH 2008

Purpose: This course reflects the recommendations of the MAA’s Mathematical Education of Teachers Document and the
Georgia P-16 Council’s Plan for Having a Qualified Teacher in Every Public School Classroom by 2006. Both documents support the philosophy that today’s mathematics teachers must possess an in-depth understanding of the mathematics they will teach; be able to nurture collaboration, critical thinking, hands-on exploration, and problem-based inquiry; facilitate the appropriate use of manipulatives, multiple forms of technology, and activities that acknowledge multiple intelligences and learning styles. The intent and focus of this course is not an exhaustive exercise in symbol manipulation . Opportunities for exploring new ideas; solving problems using multiple strategies, manipulatives, graphing calculators and other available technologies; and interpreting solutions, reasonableness of answers, and efficiency of various methods form the foundation for increasing the pre-service teacher’s ability to bring students of diverse backgrounds to high levels of achievement.

Metacognitive Model & Teacher Education Program Competencies:
The NGCSU Mathematics Education Program prepares teachers to assume within the school community the roles of Decision-
Maker, Facilitator, and Leader as identified in the metacognitive model. Twelve Teacher Education Program competencies
reflecting the model are aligned to a specific role. Overlap into more than one role and mathematics course may occur. Current research and professional standards identify these competencies as important for effective teaching (NBPTS and ASCD

Decision-Maker Facilitator Leader
Assessment Individual Differences Ethical Perspectives
Planning Subject Matter Knowledge Reflection/Metacognition
Problem Solver Communication Professional Leadership
Methods, Materials, Resources Classroom Management Research & Evaluation

Instructional Methods: This course will develop a mathematical and pedagogical knowledge base that fosters the development of the pre-service teacher as a facilitator, decision maker, and leader through the use of a variety of:
• instructional strategies and methods including lecture, guided discussion, modeling, simulations, cooperative and collaborative learning groups, student presentations, and hands-on activities that actively engage students in the learning process; and
• instructional materials, assessment techniques, and scoring rubrics that reflect the spirit of national standards such as the NCTM Principles and Standards (2000) and the MAA’s Mathematical Education of Teachers Document Draft (2000);
diverse learning styles; and multicultural components.

Technology: Using technology as a tool for learning and doing mathematics and for accessing instructional materials via the Internet is an important component of this course. A graphing calculator is mandatory with any version of the TI-83 and TI-84 models strongly suggested. Other technology will be used including data collection devices such as the Calculator-Based Ranger (CBR) with a built-in motion detector and the Calculator-Based Laboratory (CBL) with temperature probes, pressure probes, and microphones; and TI-InterActive! Students are expected to have an e-mail address either on or off campus.

Evaluation Methods: Student performance will be evaluated through the use of tests, a variety of in-class activities (including mathematical activities, discussions, and presentations), home work problems, and a final exam.
The standard grading scale (A = 90-100, B = 80-89, C = 70-79, D = 60-69, F = 0-59) will be used based on the following

50% Exam average (3 exams will be given in addition to the final exam)
15% In-class activities and participation
15% Home work
20% Final Exam

Make-Up Work: If an assignment is take home, it will not be accepted after the due date. It is the student’s responsibility to check with the professor to determine if a take home assignment was given during an absence. If a student is absent on the day that an assignment is due, it is the student’s responsibility to make sure that the assignment is given to the professor by the due date. Make-up tests and assignments will not be allowed. If a student misses a test and has a valid, properly-documented reason, the final exam grade may count in place of that test score. There will be absolutely no make-ups allowed for the final exam, which will be given Wednesday April 22, 2009, from 3:30-5:30 pm.

Attendance Policy: Attendance each day in class is mandatory. If a student misses 5 or more class meetings without valid, extreme circumstances documented, he or she may be withdrawn from the class and assigned a grade of WF. If you must miss class for any reason, please notify me before the absence. If an emergency arises, please notify me as quickly as is reasonably possible. Tardiness is not acceptable. Students who show up to class several minutes late or leave early may be marked absent for the period.

Class evaluations: Class evaluations at NGCSU are now conducted on-line through Banner. Evaluation of the class is considered a component of the course and students will not be permitted to access their course grade until the evaluation has been completed. The evaluations will be accessible beginning one week prior to Final Exam week. Specific instructions will be made available when the surveys are activated.
