A pivotal theorem which is of critical importance to statistical inference in probability and statistics is the Central Limit Theorem (CLT). The theorem concerns the sampling distribution of random samples taken from a population, including population distributions that do not have to be normal distributions. This paper contains a brief history of…

The Calculators in Primary Mathematics Project was a long-term investigation into the effects of the introduction of calculators on the learning and teaching of primary mathematics. The Australian project commenced with children who were in kindergarten and grade 1 in 1990, moving up through the schools to grade 4 level by 1993. Children were…

Some thoughts on the classroom use of hand calculators are offered, together with advice on their purchase and references to related research. (SD)

Geometry is an important branch of mathematics. Geometry curriculum can be enriched by using different Technologies such as graphing calculators and computers. Logo-based different software packages aim to improve conceptual understanding in geometry. The goals of this paper are i) to present theoretical foundations of any compute software…

An overview is provided of the current status of technical and vocational mathematics in the two-year college. Section I traces the development of technical math courses and discusses their function in the two-year college curriculum. Section II examines the use of applied math problems appropriate to particular vocational programs as an aid in…

This compilation of references on calculators covers the uses of calculators in the primary, middle, and lower secondary grades. It includes the greater part of the relevant literature available in the English language up to the summer of 1981. Selection of the American literature is rigorous, while the list of recent publications in the United…

This seasonal project integrates the skills of typing, photocopying, calculating, composing, alphabetizing, and human relations, which the student has acquired during the first part of the Administrative Support Occupations II course. The activity is a simulation that involves a small, specialty, mail-order business selling novelty items for…

This Information Bulletin reviews nine books or kits providing useful activities for using calculators in grades 2-9, plus several articles providing constructive suggestions. The materials were selected on the basis of five criteria: ease of integration within the present curriculum, power to sustain interest, degree of attention to essential…

A study was conducted to: (1) observe through a case study approach the exploratory behavior exhibited by 8-year-old boys and girls when calculators were made available in problem-solving situations; (2) investigate changes that occur in the kinds of arithmetical problems children construct following the introduction of calculators; and (3)…

This report is an evaluation of a New York City school district educational project funded under Title I of the Elementary and Secondary Act of 1965. The major objective of the program was to increase student competency in math computational skills. Approximately 3,000 high school students in grades 9 through 11 from 32 high schools were selected…

Suggests two uses for the programmable calculator in the freshman chemistry laboratory: as a means of determining whether or not a student's raw data from a laboratory experiment fall within acceptable tolerance limits; and as a means of checking the reliability of unknowns and grading on quantitative experiments. (MLH)

Nineteen Calculus II students were randomly sampled and divided into calculator (n=9) and noncalculator (n=10) groups. These students were asked to "think aloud" while solving 24 Advanced Placement calculus problems. Each student interview was videotaped, coded and analyzed for reasoning process as well as outcome. The results indicated…

Presented are twenty essays related to applications in school mathematics and aimed at the classroom teacher. The essays use numerous examples and illustrations that provide the teacher with something tangible for immediate use. Four thematic areas are addressed: (1) What are applications?; (2) Why include applications in school mathematics?; (3)…

An activity for secondary schools is presented and discussed which may be explored with a programmable calculator. The activity is non-standard and could not be easily explored without the use of a programmable calculator. Related activities are also discussed. Flow charts and programs for different programmable calculators are presented. (MP)

Results of a survey, concerned with the use of calculators conducted following a calculator workshop, are reported. Respondents were 400 elementary and secondary teachers and administrators. The report includes recommended uses of calculators by grade level and suggestions for staff development. In general, results indicate teachers and…
