“…These figures do not include special and adult education.7 According toDe Hoyos, Holland, and Troiano (2015), there is a gradual increase in Argentina's Science scores between 2006 and 2012, but it is not statistically significant at conventional levels (95 percent).8 Argentina participated in PISA 2015, but its results were excluded from the main report due to problems with sample design. However, CABA participated as an adjudicated region and was included in the results.9 In a similar vein, results of the UNESCO Second Regional Comparative and Explanatory Study (SERCE), applied to students of third and sixth graders, show that only 11.4 percent of sixth-grade students were able to explain everyday situations based on scientific evidence, use models to explain natural phenomena, or draw conclusions based on data (UNESCO 2009).…”
