Do high school Sistema COC students demonstrate higher achievement on a simulated national standardized exam?
In Brazil, students with the highest exam scores earn places at the best universities in the country. High schools must prepare their students for these exams, the most important of which is the Exame Nacional do Ensino Médio (ENEM) or National Exam of Upper Secondary Education.
Sistema COC is an integrated learning system for Brazilian private schools. Its multimedia resources and cross-curricular approach aim to prepare high school students to progress to higher education, particularly by achieving high marks on the ENEM.
Pearson explored the relationship between the use of Sistema COC with learner outcomes like students’ achievement in the simulated national assessments. We conducted a study comparing SimENEM results, a practice exam, for students in Sistema COC schools with similar students in public and private schools not using Sistema COC1.
We found that Sistema COC students statistically outperformed other similar non-Sistema COC public school attendees in SimENEM subjects language and natural science by a large margin (by 21 and 17 percentile points). There were no significant differences in math and human science. The research team equated comparison groups by matching examinees older than 18, on the previous year’s (2017) SimENEM scores, grade level, number of people living in the household and years attending the same school.
There were no significant differences in performance between COC students and non-COC private school students in Language, Math, Human Science and Natural Science.
