Abstract
We investigate the relationship between math attitude and students’ math scores using data obtained from PISA 2012 and a 2SLS model. Math attitude is approximated by an indicator that takes into account intangible (parental attitude, student instrumental motivation and student math anxiety) and tangible (parental help in math homework) factors. The presence of one family member in a math-related career is our instrumental variable. We find that an increase of one standard deviation in math attitude increases the student score by approximately 30 points, a relevant effect since 40 points is the equivalent of one year of schooling.
