Motivation in mathematics and science appears to be more important to STEM occupational choice than ability. Using the expectancy value model, parents may be able to recognize potential barriers to children's selection of a STEM occupation and take actions to help facilitate talent development. These are especially important for parents of elementary school-aged children because the current climate of high-stakes testing discourages the teaching of science in elementary school. The components of the expectancy value model are discussed in this article: self-efficacy; attainment value; utility value; and interest-enjoyment value, while reducing the perception of cost. When expectancy-value is increased, children will be more motivated for science and more likely to plan to pursue those career options.
