Abstract Details

2017, Master of Arts, Case Western Reserve University, Psychology.
Strategies used to solve addition problems without pencil and paper have been evaluated and connected to math achievement in multiple studies of children and adults. However, only a few studies have used adolescent samples, and addition strategies have not been evaluated in a behavior genetic framework. In this study the addition strategies used by a group of adolescent twins (77 MZ pairs and 136 DZ pairs) from the Western Reserve Reading and Math Project were evaluated. Participants solved 20 addition problems (14 simple and 6 complex) and reported the strategies that they used to solve each problem. Memory based strategies included retrieval and decomposition and procedural strategies included counting. Measures of strategy use on the task were taken from previous studies of children and adults. The measures that best characterized adolescent strategy use were the child and adult measures that described frequency of retrieval and decomposition. All measures of strategy use had significant nonshared environmental influences, and none of the measures had significant shared environmental influences. Further, strategy use measures for complex problems had a significant estimate of heritability.
