Forty-three junior high learning disabilities programs were surveyed to identify students either specifically disabled in arithmetic (SLDARITH, N=30) or specifically disabled in reading (SLDREAD, N=30). Three types of data were analyzed: size of LD program and school, Wechsler Intelligence Scale for Children (WISC) Verbal and Performance scores,…

Designed for use by students at beginning high school through adult levels, this manual contains seventeen lessons on uses of the electronic hand calculator. Within each of the eight sections lessons presented include objectives, procedural information, examples, and problems to be solved. Following an introductory lesson to the calculator,…

Students in two biostatistics courses at the Cornell Medical College and in a course in applications of computer science given in Cornell's School of Industrial Engineering were given access to an interactive package of computer programs enabling them to perform statistical analysis without the burden of hand computation. After a general…

A computer program to perform a Monte Carlo simulation of counting experiments was written. The program was based on a mathematical derivation which started with counts in a time interval. The time interval was subdivided to form a binomial distribution with no two counts in the same subinterval. Then the number of subintervals was extended to…

TO DEVELOP A BETTER MATHEMATICAL BASIS FOR FACTOR ANALYSIS, A MATHEMATICAL APPROACH WAS FORMULATED FOR FIXING COMMUNALITIES AND THEIR COMPLEMENTS, UNIQUENESSES, AS WELL. WHILE THE INVESTIGATOR WAS UNABLE TO PROVE THAT MINIMUM-TRACE CRITERIA FIX COMMUNALITIES UNIQUELY, A SET OF IDENTITIES AND INEQUALITIES WAS LOCATED AMONG THE COMMUNALITIES AND,…

Described is a calculator race that is designed to require a fast touch with the calculator and also the ability to apply mathematical knowledge. Sample questions are given. (MP)

Five reasons are discussed for teaching estimation involving utility, problem solving, concept formation, calculations, and attitude. Specific types of estimation are analyzed and examples given. (MP)

Repeatedly taking the square root with a calculator yields numbers with logarithmic-type properties, which can be used to define the logarithm functions. (MP)

Comparing calendar years and planetary years serves as the basis of a calculator problem. (MP)

Children ranging in age from three to six years counted 7, 10, and 14 items arranged in columns or in rows. Developmental changes in the spatial strategy and the relation of strategy to accuracy were examined. (JMB)

The role of common fractions in mathematics education and in applications is discussed in light of the increased importance of calculators and the metric system. (MP)

The computer programs require the students to show that they understand the calculations by processing one set of data correctly themselves before the remaining sets are computed for them. (MP)

The study reported is the first in a series of investigations designed to empirically test the hypothesis that calculators reduce quantitative working time and increase computational accuracy, and to examine the relative magnitude of benefit that accompanies utilizing calculators compared to manual work. (MN)

A program is presented which enables a programable calculator to become a device to check the arithmetic computational skills of students. (MP)

Conjecture and proof, as opposed to numerical calculation, are presented as being the primary focus for teaching mathematics. (MP)
