Changes in test scores distribution for students of the fourth grade in Brazil: a relative distribution analysis for the years 1997 to 2005

To assess the quality of school education, much of educational research is concerned with comparisons of test scores means or medians. In this paper, we shift this focus and explore test scores data by addressing some often neglected questions. In the case of Brazil, the mean of test scores in Math for students of the fourth grade has declined approximately 0,2 standard deviation in the late 1990s. But what about changes in the distribution of scores? It is unclear whether the decline was caused by deterioration in student performance in upper and/or lower tails of the distribution. To answer this question, we propose the use of the relative distribution method developed by Handcock and Morris (1999). The advantage of this methodology is that it compares two distributions of test scores data through a single distribution and synthesizes all the differences between them. Moreover, it is possible to decompose the total difference between two distributions in a level effect (changes in median) and shape effect (changes in shape of the distribution). We find that the decline of average-test scores is mainly caused by a worsening in the position of all students throughout the distribution of scores and is not only specific to any quantile of distribution.

The impact of structured teaching methods on the quality of education

This paper estimates the impact of the use of structured methods on the quality of education of the students in primary public school in Brazil. Structure methods encompass a range of pedagogical and managerial instruments applied to the education system. In recent years, several municipalities in the State of São Paulo have contracted out private educational providers to implement these structured methods in their schooling system. Their pedagogical proposal involves structuring curriculum contents, elaboration and use of teachers and students textbooks, and training and supervision of the teachers and instructors. Using a difference in differences estimation strategy, we find that the fourth and eighth grader students in the municipalities with structured methods performed better in Portuguese and Math than students in municipalities not exposed to the methods. We find no differences in approval rates. However, a robustness check is not able to discard the possibility that unobserved municipal characteristics may affect the results.

Exchange students in Brazil: some factors behind its choice - empirical evidences from a Brazilian school

O Brasil sempre foi um lugar conveniente para se visitar em termos de cultura, diversão e entretenimento. No entanto, este estudo visa o lado educacional do país, particularmente, os estudantes estrangeiros que escolhem o Brasil para programas de intercâmbio. Fins e razões por trás das escolhas dos estudantes foram identificados através de pesquisas quantitativas e qualitativas, juntamente com a revisão da literatura já existente. A pesquisa primária foi feita por meio de entrevistas com estudantes de intercâmbio já no Brasil. Os dados coletados foram analisados e são apresentados de forma estatística, juntamente com a representação gráfica. O seguinte estudo apontou que os denominados “turistas” e, assim chamados, “money seekers”, serem os principais fatores por trás da escolha de estudantes. A pesquisa também mostra que os alunos mais satisfeitos foram os que escolheram o Brasil por causa da qualidade da universidade sede, assim como para explorar as perspectivas de emprego, juntamente com iniciar uma carreira no Brasil.
