Lancaster, Ron – Mathematics Teacher, 2016
Can you solve the following Problem? There are 200 fish in an aquarium, and 99 percent of them are guppies. How many guppies must be removed to reduce the tank's guppy population to 98 percent? The key to this problem is to work backward by using the data given in figure 2 to determine the surface area of the top of the aquarium; then determine…

Yakubova, Gulnoza; Bouck, Emily C. – Education and Training in Autism and Developmental Disabilities, 2014
Calculators are widely used in mathematics education, yet limited research examines the effects of calculators for students with mild intellectual disability. An alternating treatments design was used to study the effects of calculator types (i.e., scientific and graphing) on the mathematical performance (i.e., computation and word problems) of…

Siskind, Theresa G. – Rural Educator, 1995
Forty-eight rural high school students were randomly assigned to groups that solved math problems with paper and pencil or with calculators. Both groups displayed similar attitudes toward math. Results of a word problem test revealed that, after one week, calculator use contributed significantly to mathematical word problem achievement. (LP)
