Measuring cost: the forgotten component of expectancy-value theory, Contemporary Educational Psychology (2015), http://dx.doi.org/ Highlights We find that cost, from the expectancy-value model has recently reemerged in the literature. Student focus groups confirm that cost is salient when considering their motivation. We redefine cost to be consistent with our theoretical review and qualitative inquiry. Exploratory and confirmatory factor analyses support our theoretical cost structure. Our cost dimensions are associated with other motivation constructs and student performance. AbstractAlthough the Expectancy-Value Model offers one of the most influential models for understanding motivation, one component of this model, cost, has been largely ignored in empirical research. Fortunately, recent research is emerging on cost, but no clear consensus has emerged for operationalizing and measuring it. To address this shortcoming, we outline a comprehensive scale development process that builds and extends on prior work. We conducted a literature review of theory and existing measurement, a qualitative study with students, a Page 2 of 46 MEASURING COST 3 content alignment with experts, exploratory and confirmatory factor analysis, and a correlational study. In the literature and across our studies, we found that cost was salient to students, separate from expectancy and value components, contained multiple dimensions, and related to student outcomes. This work led to proposing a new, 19 item cost scale with four dimensions: task effort cost, outside effort cost, loss of valued alternatives cost, and emotional cost. In addition, to extend existing cost measures, careful attention was taken to operationalize the cost dimensions such that the scale could be easily used with a wide variety of students in various contexts. Directions for future research and the implications for the study of motivation are discussed.

Grading refers to the symbols assigned to individual pieces of student work or to composite measures of student performance on report cards. This review of over 100 years of research on grading considers five types of studies: (a) early studies of the reliability of grades, (b) quantitative studies of the composition of K-12 report card grades, (c) survey and interview studies of teachers' perceptions of grades, (d) studies of standards-based grading, and (e) grading in higher education. Early 20th century studies generally condemned teachers' grades as unreliable. More recent studies of the relationships of grades to tested achievement and survey studies of teachers' grading practices and beliefs suggest that grades assess a multidimensional construct containing both cognitive and non-cognitive factors reflecting what teachers value in student work. Implications for future research and for grading practices are discussed.

The Mathematical Resilience Scale measures students’ attitudes toward studying mathematics, using three correlated factors: Value, Struggle, and Growth. The Mathematical Resilience Scale was developed and validated using exploratory and confirmatory factor analyses across three samples. Results provide a new approach to gauge the likelihood of student participation and persistence in mathematics.
