Explores some ideas for the imaginative use of a graphics calculator in introductory statistics teaching. (Author/ASK)

This paper explores questions about linear relationships through the use of pattern. Participants in the session generated and extended patterns and used calculators to investigate the relationships. Examples from current Texas Instruments (TI) books and U.S. textbook series, plus examples from proposed TI materials are shared. These activities…

Describes a calculator exercise that can help students develop a better visual and numeric feel for Newton's method. (KHR)

Explores the extent and nature of students' calculator usage as determined from examination scripts in the Western Australian Calculus Tertiary Entrance Examination. Discusses errors made and understanding called upon for seven questions. Discusses instruction and assessment of skills associated with graphical interpretation. (Author/KHR)

Presents a study in which three classes of grade 10 students worked with graphics calculators throughout, five classes used them for approximately two months, and four classes did not use them at all. Posttest results showed that students who had worked with graphics calculators tended to attempt more problems and obtain higher test scores than…

Suggests a model for the learning and reinforcing of algebraic manipulative skills through the intensive use of group work using computer algebra systems (CAS). Suggests a model for assessing students through group work, for using the TI-92 as a self-assessment tool, and in cross-curricular activities. (Author/ASK)

Describes how to teach the coefficient of determination and correlation coefficient. Includes a worksheet for correlation and regression activities. (KHR)

Describes the different ways in which two pioneering Australian teachers adapted their teaching to use computer algebra systems (CAS). One teacher used CAS with the primary goal of increasing understanding but restricted student use. The other teacher adopted CAS as an extra technique for solving standard problems, emphasizing time saving routines…

Presents a way of using greeting cards created by graphing calculators to teach the transformation of functions. Illustrates the steps of making a calculator greeting card and students' descriptions of transformations. (KHR)

Presents two examples of using the limitations of calculators to help students understand important mathematical ideas. The first example shows how a simple algebraic calculation can make a recursive model work long enough to perform the job at hand while the second shows how the limitations of a calculator can be used to introduce the need for…

Technology offers the opportunity to study larger, more difficult group structures and perform tedious computations quickly while maintaining the focus on concepts over calculations. Explores several technology options available to the instructor as well as sample assignments and class explorations that effectively integrate technology within the…

Discusses the rationale behind the technique of rationalizing the denominator in algebra. Argues that the importance of this technique is greatly exaggerated and is usually unnecessary. Examines an appropriate application of rationalizing the denominator. (ASK)

Provides evidence of differences in students' ability to solve problems with and without a computer algebra system. Indicates that almost without exception, the TI-92 students were more successful at symbolically solving problems than comparison students. Observes improved performance on all three levels of problems: (1) directive computational;…

The increasing availability of computer algebra systems (CAS) for the high school classroom is expected to have a significant effect on how algebra is taught, when it is taught, and the expected learning types. This paper reports on a computer algebra approach to the teaching of algebra to 13-16 year old students in a high school in Melbourne,…

This paper reports on a mathematics course in an Austrian high school that focuses on probability distributions. Students in this course used a TI-92 during math classes, at home for doing exercises, and during math tests. The TI-92 was used as a tool for calculations and illustrations making the concepts of probability distributions easy to…
