Anemia and Child Education: The Case of Colombia
(2011) Alejandro Gaviría; Alejandro Hoyos
Welfare programs in Colombia have focused on both reducing malnutrition and hunger and increasing school attendance. But there is not much evidence on the hypothesized relationship between nutrition status and schooling outcomes. Using the National Survey of Nutritional Status in Colombia — 2005 (ENSIN) and the Demographic and Health Survey — 2005 (DHS), this paper estimates the impact of nutrition on schooling outcomes. The results suggest that anemic children have a higher probability of being overage in school. Malnutrition, defined by anthropometric measures, does not have an impact on the probability of being overage. School attendance seems to be unrelated to nutrition measures. The results are consistent under different specifications.
Determinantes de los resultados de las evaluaciones de profesores: el caso de la Universidad de los Andes
(2008) Alejandro Gaviría; Alejandro Hoyos
This paper examines the determinants of teacher and course evaluations at the Universidad de los Andes in Bogotá, Colombia. The paper explores how teacher and course characteristics affect evaluation results. Grades obtained by students directly and positively affect teacher evaluations. Class size negatively affects the results of the evaluations. Finally whether teachers are full or part-time as well as years of experience of teachers have a negligible impact on evaluations.
