Reviews the use of chi-square statistics for goodness of fit. Examines how to help students relate their earlier work with independence to the use of chi-square statistics. (KHR)

What is number sense, why it is important, how it is taught, and how it is measured are each discussed. Examples with concrete materials, calculators, and pattern recognition are included. (MNS)

Observations focusing on classroom discourse, uses of graphing calculators, nature of instructional tasks, and instructor-questioning patterns in a high school algebra course found that the teacher modified his teaching strategies and curriculum to accommodate the teaching strategies and topics that arose from the use of the graphing calculator.…

Gives a general description of reformed calculus efforts and describes experiences with two reformed calculus programs together with traditional calculus. Also provides comparisons between these three programs using teaching evaluations and student journals. (Author/MKR)

Presents a series of simple activities involving generalized two-dimensional motion topics to prepare students to study projectile motion. Uses a pair of motion detectors, each connected to a calculator-based-laboratory (CBL) unit interfaced with a standard graphics calculator, to explore two-dimensional motion. (JRH)

Presents four examples of physics problems that can be solved with a graphing calculator. Problems included deal with motion, harmonic oscillations, sound waves, and blackbody radiation. (JRH)

Describes three approaches teachers can use to help students understand the computation of numbers: calculator explorations, problem solving, and discussion topics. Specific examples are provided for primary and upper grades. (MDM)

Presents two elementary level activities designed to make math more meaningful with the help of technology. One activity involves learning about banking using computer spreadsheets and stock programs; the other uses computers and calculators to help students integrate mathematics into the study of world cultures. (SM)

Compared was the mathematical performance of secondary school students for whom a graphic calculator was a standard mathematical tool, with that of students of similar background without regular access to graphing technology. Increased achievement on symbolization tasks, especially for females, was shown for students who used the graphing…

Investigated the long-term influence of a longitudinal calculator awareness approach to numbers on British elementary students' mathematical achievements and attitudes. Teacher and student interviews and student test scores from intervention and nonintervention schools indicated that the curriculum had no substantial long-term influence on…

In this article, we will describe the results of a study of 6th grade students learning about the mathematics of change. The students in this study worked with software environments for the computer and the graphing calculator that included a simulation of a moving elevator, linked to a graph of its velocity vs. time. We will describe how the…

The need exists for methods courses to address the pedagogy issues of using graphing calculators. There needs to be a teacher candidate forum to examine their pedagogical perspectives on using graphing calculators in teaching, to explore when and how to use graphing calculators in the classroom, and to provide opportunities to practice teaching…

Presented is a supplement to two previous collections of expanded abstracts of research with calculators. Eight reports are abstracted to add to the information on the effects of calculators on achievement and learning. The critical commentary prepared by each abstractor pinpoints particular strengths and weaknesses of each study. (MP)

How children perceive doubling and halving numbers is discussed, with many examples. The use of calculators is integrated. The tendency to avoid division if other ways of solving a problem can be found was noted. (MNS)

The need to incorporate deductive reasoning in the curriculum is noted. Guidelines for developing reasoning skills and activities to develop understanding of inductive and deductive processes are provided. (MNS)
