The Importance Of Vocabulary Instruction In Everyday Mathematics, Chad Larson Jul 2007

The Importance Of Vocabulary Instruction In Everyday Mathematics, Chad Larson

Action Research Projects

In this action research study of my 6th grade math students I try to answer the question of how mathematical vocabulary plays an integral role in the understanding and learning of middle level mathematics. It is my belief that mathematics is a language, and to be fluent in that language one must be able to use and understand vocabulary. With the use of vocabulary quizzes and mathematically-centered vocabulary activities, student scores and understanding of math concepts can be increased. I discovered that many of the students had never been exposed to consistent mathematical terminology in their elementary education, which led …

A Monte Carlo Simulation Of The Birthday Problem, Stacey Aldag Jul 2007

A Monte Carlo Simulation Of The Birthday Problem, Stacey Aldag

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

Question, how many people would you need in a group in order for there to be a 50-50 chance that at least two people will share a birthday? Answer, 23 people. But how can this be? There are 365 days in a year and half of that would be 182, so why wouldn’t you need at least 182 people to have a 50-50 chance? Strangely enough the answer to this question is only 23 people are necessary to have a 50% chance at least two people in the group will share a birthday. This situation, where the answer is counter …

Department of Teaching, Learning, and Teacher Education: Master of Arts in Teaching, Summative Projects

In this action research study of my Class I School’s 5th and 8th grade mathematics, I investigated students’ connections between communication of math skills and their math abilities. I discovered that students can increase their math abilities with the opportunities to discuss their thinking as well as evaluate thinking and strategies of other students. Electronic communication can be a valuable source for students to communicate further to other students.

Evaluating Polynomials, Thomas J. Harrington Jul 2007

Evaluating Polynomials, Thomas J. Harrington

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

Computers use algorithms to evaluate polynomials. This paper will study the efficiency of various algorithms for evaluating polynomials. We do this by counting the number of basic operations needed; since multiplication takes much more time to perform on a computer, we will count only multiplications. This paper addresses the following: a) How many multiplications does it take to evaluate the one-variable polynomial, Σ= + + + + = n i i i n n a a x a x a x a x 0 2 0 1 2 ... when the operations are performed as indicated? (Remember that powers are …

How To Graphically Interpret The Complex Roots Of A Quadratic Equation, Carmen Melliger Jul 2007

How To Graphically Interpret The Complex Roots Of A Quadratic Equation, Carmen Melliger

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

As a secondary math teacher I have taught my students to find the roots of a quadratic equation in several ways. One of these ways is to graphically look at the quadratic and see were it crosses the x-axis. For example, the equation of y = x2 – x – 2, as shown in Figure 1, has roots at x = -1 and x = 2. These are the two places in which the sketched graph crosses the x-axis.

Master Of Arts In Teaching (Mat), Josh Severin

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

The number zero is a very powerful tool in mathematics that has many different applications and rules. An interesting fact about the number zero is that according to our calendar (the Gregorian calendar), there is no “year zero” in our history. There is also no “zeroth” century as time is recorded from centuries B.C. to the 1st century A.D. However, certain calendars do have a year zero. In the astronomical year numbering system year zero is defined as year 1 BC. Buddhist and Hindu lunar calendars also have a year zero. In this paper I am going to discuss many …

Hyperbolic Geometry, Christina L. Sheets Jul 2007

Hyperbolic Geometry, Christina L. Sheets

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

In general, when one refers to geometry, he or she is referring to Euclidean geometry. Euclidean geometry is the geometry with which most people are familiar. It is the geometry taught in elementary and secondary school. Euclidean geometry can be attributed to the Greek mathematician Euclid of Alexandria. His work entitled The Elements was the first to systematically discuss geometry. Since approximately 600 B.C., mathematicians have used logical reasoning to deduce mathematical ideas, and Euclid was no exception. In his book, he started by assuming a small set of axioms and definitions, and was able to prove many other theorems. …

Pythagorean Triples, Diane Swartzlander Jul 2007

Pythagorean Triples, Diane Swartzlander

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

Who was Pythagoras after which the Pythagorean Theorem is named? Pythagoras was born between 580-572 BC and died between 500-490 BC. Pythagoras and his students believed that everything was related to mathematics and that numbers were the ultimate reality. Very little is known about Pythagoras because none of his writings have survived. Many of his accomplishments may actually have been the work of his colleagues and students. Pythagoras established a secret cult called the Pythagoreans. His cult was open to both females and males and they lived a structured life consisting of religious teaching, common meals, exercise, reading and philosophical …

Perimeter And Area Of Inscribed And Circumscribed Polygons, Lindsey Thompson Jul 2007

Perimeter And Area Of Inscribed And Circumscribed Polygons, Lindsey Thompson

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

This paper looks at comparing the perimeter and area of inscribed and circumscribed regular polygons. All constructions will be made with circles of radius equal to 1 unit. To begin this exploration, I created a circle with a radius of 1(for my purposes I used 1 inch as my unit of measure). I chose my first construction to contain the most basic regular polygon, an equilateral triangle. A regular polygon implies that all sides of the figure are equal and all interior angles of the figure are congruent. My first construction shows an equilateral triangle inscribed in a circle (see …

The Volume Of A Platonic Solid, Cindy Steinkruger Jul 2007

The Volume Of A Platonic Solid, Cindy Steinkruger

Department of Mathematics: Master of Arts in Teaching, Exam Expository Papers

A regular tetrahedron and a regular octahedron are two of the five known Platonic Solids. These five “special” polyhedra look the same from any vertex, their faces are made of the same regular shape, and every edge is identical. The earliest known description of them as a group is found in Plato’s Timaeus, thus the name Platonic Solids. Plato theorized the classical elements were constructed from the regular solids. The tetrahedron was considered representative of fire, the hexahedron or cube represented earth, the octahedron stood for gas or air, the dodecahedron represented vacuum or ether (which is made up of …

Using Cooperative Learning To Promote A Problem-Solving Classroom, Amy Nebesniak Jul 2007

Using Cooperative Learning To Promote A Problem-Solving Classroom, Amy Nebesniak

Department of Teaching, Learning, and Teacher Education: Master of Arts in Teaching, Summative Projects

In this action research study of my eighth grade mathematics classroom, I investigate the benefits of cooperative learning, the support structures needed to promote a cooperative learning environment, and students’ ability to transfer the cooperative learning skills into less structured problem solving situations. The data analysis reveals that cooperative learning increases students’ confidence level as well as their involvement in the learning process. In order to create successful teams, students require my providing support structures and modifying the support for each group of students. Finally, students are able to more effectively apply their cooperative skills in concrete situations as compared …

A Study Of The Role Of Mnemonics In Learning Mathematics, Kathy Delashmutt Jul 2007

A Study Of The Role Of Mnemonics In Learning Mathematics, Kathy Delashmutt

Department of Teaching, Learning, and Teacher Education: Master of Arts in Teaching, Summative Projects

In this action research study of my fifth grade mathematics teaching, I investigated student engagement levels in the classroom, with a specific interest in the importance and effectiveness of mnemonics in learning mathematics for all learners. I defined mnemonic instruction as a strategy that provides a visual or verbal prompt for students who may have difficulty retaining information. It is a memory enhancing instructional strategy that involved teaching students to link new information that is taught to information they already know. I investigated mnemonics effectiveness in my classroom by using two student interviews, a teacher survey, two student surveys and …

Increasing Conceptual Learning Through Student Participation, Janet Timoney

Action Research Projects

In this action research study of my 9th grade Algebra I classroom, I investigated the idea of presenting problems at the beginning of class. Data was collected to determine if presenting problems at the beginning of class would have an effect on students’ conceptual learning, verbal communication and confidence. It was also my intention that this project would have a positive impact on my students both academically and mentally with increasing their confidence with mathematical problems. I discovered that presenting problems at the beginning of class did impact my students’ overall abilities and achievement. It seemed to improve their volunteerism …
