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…

Refinements of work with calculator algorithms previously conducted by the author are reported. Work with "chaining" and the doing/undoing property in addition and subtraction was tested with 24 third-grade students. Results indicated the need for further instruction with both ideas. Students were able to manipulate the calculator keyboard, but…

The purpose of this study was to compare the effects of a fourth-grade arithmetic sequence based on calculator flow-charting with those of traditional textbook instruction. Both achievement and attitude were compared. Students were matched on the basis of intelligence (Otis Quick-Scoring Mental Ability Beta Test Form EM) and sex, and then randomly…

These worksheets deal with sums of numbers. Students are asked to find the relationship between the last number in the series, the number of addends, and the sum. (MP)

Describes a hand held calculator exercise for computing the Rydberg Constant accurately. (SL)

An attitude survey and arithmetic tests were given to samples of students in order to quantify the benefit obtained from their use of calculators. Results showed that the use of the calculators does improve students' arithmetic performance with the less able students showing about twice the improvement of the more able. (MN)

A program involving the use of calculators for an eighth-grade class is described. Guidelines to assist those in the process of initiating a program involving the use of calculators are included. (MN)

Provides examples from advanced secondary school science which are amenable to the use of a programmable calculator. Compares the use of the calculator to a computer terminal. (CP)
