...is the imposition of the "socioconstructivist" model, from the left. A pseudoscientific model full of empty expressions and jargon, as is typical of pseudosciences, which opposes the traditional pedagogical model: emphasizing the memorization of information passed from teacher to student*. However, the problem with education, and not only in Brazil, is not just the model adopted, but that, on average, our population already presents cognitive limitations that are not reflections of personal experiences or social deficiencies, but of their own biology, of something that is practically determined at birth, of what one can achieve... Therefore, regardless of the model adopted, even if it may worsen the educational level, the cognitive limitations of the majority of the population, at least in relation to academic aspects, contribute massively to determining the potential proficiency that can be acquired. So, even if the software (the "education" model) is the best possible, it will still depend on the hardware (intrinsic or biological characteristics) that will continue to limit its results. A wonderful education model will not, miraculously, increase, for example, the average IQ of the Brazilian population, which is currently around 85 points, well below the Greenwich average of 100.
However, this is the misguided explanation that the so-called Brazilian "right" has decided to adopt, of course, exclusively blaming the influence of the "left" on education and completely disregarding these fundamental aspects, as they are also "controversial" or "polemical" nowadays. Yet another demonstration of how weak and submissive the "right" is in relation to the cultural hegemony of its antagonist in traditional institutions, since an "educativist" explanation (education for education's sake) has typically been adopted by the "left," even as a way to avoid a more objective and intellectually honest approach that would inevitably lead it to highlight these "fundamental aspects." However controversial, in short, it would force one to point to the "white elephant." For example, highlighting that Brazil has low academic performance because a significant portion of its population is composed of Afro-descendants (because they tend to have {on average} low cognitive abilities compared to other populations, such as European whites and East Asians of Asian descent), and all that litany of the "totalitarians of good" would come to the fore: "fascism," "scientific racism," "Nazism"... In short, a cowardly "right wing" submissive to the dominant "progressive" moral code...
* The socio-constructivist model, based mainly on Lev Vygotsky, proposes that learning occurs through social and cultural interaction (excerpt taken from an explanation of AI) and not through a previously established and universally ratified logical cognitive method as effective.
