This dissertation consists of two chapters on topics in economics of education. In the first chapter, I develop and estimate an equilibrium model of endogenous instruction and student effort in order to empirically investigate the relationship between instructional choices, classroom composition, and student achievement in elementary school. The…

Learning in the sciences is difficult for students from elementary school to university due to misconceptions, or incorrect prior knowledge, interfering with the acquisition of new knowledge. The process of replacing previously incorrect ideas with new and accurate ones is referred to as conceptual change. Which factors and to what extent they…
