Instruction in the Process of Constructing Proofs One of the primary goals of this book is to develop students' abilities to construct mathematical proofs. From the Back Cover: Focusing on the formal development of mathematics, this book demonstrates how to read and understand, write and construct mathematical proofs.

This gives students a strong introduction to an important mathematical idea, while providing the instructor a consistent reference point and an example of how mathematical notation can greatly simplify a concept. Emphasis on Active Learning One of the underlying premises of this text is that the best way to learn and understand mathematics is to be actively involved in the learning process. For example, Chapter 5 can be covered be In Chapter 4, we take a break from introducing new proof techniques. Important features of the book include: Emphasis on writing in mathematics nstruction in the process of constructing proofs Emphasis on active learning. This type of course is becoming a standard part of the mathematics major at most colleges and universities. The three sections of Chapter 5 are devoted to proofs using mathematical induction. A standard one-semester course in constructing and writing proofs should cover the first six chapters of the text and at least one of Chapter 7, Chapter 8, or Chapter 9. Content and Organization Mathematical content is needed as a vehicle for learning how to construct and write proofs. Includes ";Activities"; throughout that relate to the material contained in each section. Improve their quality of communication in mathematics.

The purpose of the Preview Activities is to prepare students to participate in the classroom discussion of the section. These activities can be done individually or in a collaborative learning setting, where students work in groups to brainstorm, make conjectures, test each others' ideas, reach consensus, and, it is hoped, develop sound mathematical arguments to support their work.

The primary goals of the text are to help students: Develop logical thinking skills and to develop the ability to think more abstractly in a proof oriented setting.

Other preview activities will introduce new concepts and definitions that will be used when that section is discussed in class. Various proof techniques are employed in the study of injections, surjections, composition of functions, and inverses of functions. This gives students a strong introduction to an important mathematical idea, while providing the instructor a consistent reference point and an example of how mathematical notation can greatly simplify a concept. Some Preview Activities will review prior mathematical work that is necessary for the new section. The idea of an "element-chasing proof" is introduced in Section 4. Consequently, most students complete their study of calculus without seeing a formal proof or having constructed a proof of their own. He works mostly in the areas of combinatorics and graph theory. Content and Organization Mathematical content is needed as a vehicle for learning how to construct and write proofs. Includes ";Activities"; throughout that relate to the material contained in each section. Instruction on how to write proofs begins in Section 1. The mathematical content that is introduced to illustrate these proof methods is some elementary number theory, including congruence arithmetic. The transition is from the problem-solving orientation of calculus to the more abstract and theoretical upper-level courses. The mathematical content for this text is drawn primarily from elementary number theory, including congruence arithmetic; elementary set theory; functions, including injections, surjections, and the inverse of a function; relations and equivalence relations; further topics in number theory such as greatest common divisors and prime factorizations; and cardinality of sets, including countable and uncountable sets. Since this is a text that deals with constructing and writing mathematical proofs, the logic that, is presented in Chapter 2 is intended to aid in the construction of proofs. It is often referred to as a "transition course" from the calculus sequence to the upper level courses in the major.

For example, Chapter 5 can be covered be However, it is unreasonable to expect students to go out and learn mathematics on their own. In Chapter 4, we take a break from introducing new proof techniques.
