About MATH 3242

For Students in this Course

 

MATH 3242 is one of three mathematics courses designed to prepare you to teach mathematics to students in grades PreK-5.  This course focuses on geometry concepts whereas MATH 3241 focuses on number sense, and the focus of MATH 4260 is data analysis, probability, and statistics. 

 

Research conducted by numerous groups and commissions indicate that the old ways of teaching and learning mathematics are not preparing students to meet the demands of our technological society.  The National Council of Teachers of Mathematics (NCTM) has extensively studied how to teach mathematics better in grades PreK-12 and has produced the document Principles and Standards for School Mathematics (PSSM) with recommendations for this purpose.  The Conference Board of the Mathematical Sciences (CBMS) produced a report The Mathematical Education of Teachers with recommendations for preservice mathematics education.  It is the advice of these groups and others that for teachers to teach in ways recommended by current research, they need a far deeper understanding of the mathematics they will teach than has been common in the past.  The new Georgia Performance Standards for Mathematics were written to align with the recommendations from NCTM.

 

Therefore, the goal of this course is to help you as a future elementary school teacher to develop a deeper understanding of the concepts of geometry. The emphasis will be on reasoning and problem solving rather than on memorizing a rigid set of rules.  In this way, it is hoped that you will gain a sense of mathematics as a dynamic intellectual enterprise as opposed to a static list of rules and formulas.  Keep in mind that the material taught in this course will go beyond that which is normally taught in elementary school.  This is by design and supported by Judith Sowder and her colleagues at the Center for Research in Mathematics and Science Education at San Diego State University who claim an elementary teacher’s knowledge should go beyond the mathematics that is presented in elementary textbooks.  Their description of a truly knowledgeable teacher is one who “can deal with students' insightful moments or their misconceptions, can recognize and seize opportunities for fruitful digressions, can reject textbook organization when it does not match their own understanding, and can choose instructional representations that reflect a deep understanding of the topic and that invoke basic concepts and principles."  Thus, it is not enough for you to know how to do elementary mathematics—your knowledge and understanding must go significantly beyond this level.

 

MATH 3242 will be taught in a way to prepare you to teach geometry in grades K-5 as recommended by NCTM, CBMS, and the Georgia Department of Education.  However, the purpose of this course is to provide you with mathematics content, not the teaching methodologies that may or may not accompany the presentation of such material to elementary students.  While we will undoubtedly discuss such things from time to time, the focus of the course is on developing your mathematical understanding of geometry and not on pedagogy.  You will examine in depth geometry concepts that are taught in the elementary school.  Understanding and explaining “why does it work this way?” or “why can’t it work this way?” will be a common theme as these concepts are investigated.  Certainly you already know some geometry concepts at a certain level, but in order to be a knowledgeable teacher, you must learn to think about and explain the concepts in a new and deeper way.  Please don’t underestimate the importance of developing this new and deeper understanding.  It is hard work to develop this understanding so you are asked to be patient with yourself, with your classmates, and with me.  Please do not get discouraged but instead continue your efforts to develop a deep understanding—it will pay off.

 

In order to achieve this depth of understanding and to succeed in the course, you will need to engage yourself in the material and take responsibility for your own learning.  Don’t hesitate to ask questions, but don’t be offended if you are asked to continue thinking with a hint or a question.  Be willing to try out ideas and to modify them if necessary.  Learning for true depth of understanding requires that you be very active in seeking this understanding.  Deep conceptual understanding cannot be achieved by passive absorption of the material.  Be willing to make mistakes but to learn from your mistakes.  Be willing to confront your misconceptions.  Be willing to learn from others.  Don’t give up when answers don’t immediately come to you. 

 

The course will challenge you to think differently about what it means to teach and to learn mathematics.  You will probably be uncomfortable at times.  You will probably be frustrated at times.  You will probably wonder why we “aren’t doing math like we’ve always done it.”  However, please remember the goal of the course is to allow you to develop a deep understanding so that you will be prepared to teach mathematics as envisioned by NCTM and CBMS.  I ask for you to be open to new ideas and to keep your eyes on this goal. 


But are you wondering why you are taking a course to teach geometry in elementary school?  If so, read on……

 

 

Through the study of geometry, students will learn about geometric shapes and structures and how to analyze their characteristics and relationships.  Spatial visualization—building and manipulating mental representations of two- and three-dimensional objects and perceiving an object from different perspectives—is an important aspect of geometric thinking….  Geometry is more than definitions; it is about describing relationships and reasoning.

     One important reason to study geometry is that it promotes the ability to visualize and mentally manipulate objects in space.  This is a necessary skill for a number of professions.  For example, a surgeon or dentist must be able to visualize the steps in and outcomes of an operation, a carpenter must be able to see different designs in his or her mind’s eye, an architect must be able to visualize many different possibilities for a building that satisfies certain design criteria, a clothes designer must be able to visualize how pieces of fabric will fit together to make a garment. 

     According to the report “What Work Requires of Schools” of the U.S. Department of Labor, being able to “see things in the mind’s eye” is a foundational skill for solid job performance.  In order to be able to foster this in your students, you must first foster it in yourself.
