Which Investments Improve Student Performance? The Impact of Extracurricular Activities, Paid Classes, and At-Home Internet Use on Student Performance in Secondary School

Abstract

The importance of education is acknowledged by modern society. As more and more people are willing to invest in education to improve students’ performance, the question of which areas of investment contribute most strongly to better academic performance arises. Parents can choose to involve their children in extracurricular activities, or they can choose to pay for additional classes outside of regular schooling. In addition, the use of technology, or, more specifically, access to the Internet at home, is becoming more and more common, and its influence on student performance is a popular topic of study. In this paper, we use two experiments to uncover the factors that influence students’ performance in Math and Portuguese Language and to support strategies for investment in education.
