How confident are students in their ability to solve mathematics problems?

On average across OECD countries, students’ belief that they can solve mathematics problems(mathematics self-efficacy) is associated with a difference of 49 score points in mathematics – theequivalent of one year of school.There is a strong connection between how confident students feel about being able to solve pureand applied mathematics problems, and whether or not they were exposed to similar problems inclass.When comparing students with similar academic performance and socio-economic status, thosewhose parents expected that they would enter university generally reported greater mathematicsself-efficacy than those whose parents did not hold such high expectations for them.
