Describes a project involving a short car trip in which students experience an early opportunity to work in teams, think about mathematics, gather and analyze speed and distance data, and produce a report on their findings. Provides a typical-authored solution. (Author/ASK)

Presents an experiment to design a precalculus topic that would help prepare students for limits in differential calculus. Emphasizes the topic to enhance the interpretation of graphs and to be applicable in both technology-based and traditional precalculus courses. Uses graphing calculators to help students observe the results of their…

Describes an experimental study in which two sections of calculus were taught using the same materials, except one section was enhanced with the computer algebra system Mathematica. Results indicated that the students in the technology group had advantages to understanding certain key topics in calculus such as limits, derivatives, and curve…

Presents activities that engage students and promote discussion emphasizing the history of mathematics, diversity, and multiculturalism. Six activities included are Crossword Puzzle, Date of Event, Quotes Matching, Famous Mathematical Expressions, Calendar Scramble, and Map Puzzle. Also lists related World Wide Web sites. Contains 15 references.…

Argues that although differential equations are billed as applied mathematics, there is rarely any hands-on experience incorporated into the course. Presents a laboratory project that requires students to obtain data from a physics lab and use that data to compute the coefficients of the second order differential equation, which mathematically…

Describes a nine-hour, three-sequence mathematics course in the elementary teacher certification program at Texas Tech University. Emphasizes the development, philosophy, design, and implementation of the sequence. Presents excerpts from the activities and group exercises outlined for the course. Contains 15 references. (Author/ASK)

Discusses the properties of the equation y"+ay=0, a basic equation in differential equations classes which is well known to have periodic solutions. Explores similar but more complicated equations using a graphing calculator to ask questions about the nature of the solutions and to generate conjectures from examples. Lists some equations and…

Illustrates the qualitative nature of the differences between reform courses and traditional courses based on the types of student questions and comments generated in reform classes ranging from college algebra to multivariable calculus. (AIM)

Presents an alternative to using a single-class-period test to assess a college student's knowledge in the mathematics area. Evaluation of student mathematical knowledge and understanding of concepts is improved when students are given opportunities to design problems and solutions, applying classroom-acquired knowledge to new situations. Such…

Describes an experimental course in which the programming language ISETL served as a tool for exploring concepts in abstract algebra, and identifies instructional strategies that facilitate the successful use of ISETL. Offers informal observations regarding the effectiveness of this approach. (13 references) (Author/MKR)

Hypermedia provides an easy-to-use option for adding visualization, via the computer, to the classroom. Some examples of this medium are presented, including applications in basic linear algebra and calculus, and a tutorial in electromagnetism. (Author)

Examines infinite sets and cardinality classifications of empty, finite but not empty, and infinite through discussions of numbers that fall into particular categories. Categories discussed include perfect numbers, Mersenne primes, pseudoprimes, and transcendental numbers. Discusses the Null Or Infinite Set Effect (NOISE) and infinitude resulting…

Prospective secondary teachers can explore mathematics at their own level by using the law of cosines to establish connections between topics that are usually taught separately such as cosine of the difference of two angles, Cauchy's inequality, determinants, sine of the difference of two angles, triangle inequality, and inner product of two…

A major cause of the difficulty undergraduate mathematics majors have with the transition from elementary to advanced mathematics courses is that advanced courses require students to understand how mathematics is created. Describes a course whose main purpose is to introduce students to the creative process in mathematics. The course consists of…

Describes a mathematics reasoning course at Drake University and efforts to introduce collaborative, small-group, mixed-ability activities into the classroom. Comments on the ease, difficulties, rewards, and demands involved. Discusses student and instructor attitudes towards the collaborative activities. (AIM)
