evaluative and normative education

 There are various disagreements about whether evaluative and normative aspects should already be included in the definition of education and, if so, what roles they play. An important distinction in this regard is between thin and thick definitions. Thin definitions aim to provide a value-neutral description of what education is, independent of whether and to whom it is useful. Thick definitions, on the other hand, include various evaluative and normative components in their characterization, for example, the claim that education implies that the person educated has changed for the better. Otherwise, the process would not deserve the label "education". However,
different thick definitions of education may still disagree with each other on what kind of values are involved and in which sense the change in question is an improvement. A closely related distinction is that between descriptive and prescriptive or programmatic conceptions. Descriptive definitions aim to provide a description of how the term "education" is actually used. They contrast with prescriptive definitions, which stipulate what education should be like or what constitutes good education. Some theorists also include an additional category for  definitions, which are sometimes used by individual researchers as shortcuts for what they mean when they use the term without claiming that these are the essential features commonly associated with all forms of education .Thick and prescriptive conceptions are closely related to the aims of education in the sense that they understand education as a process aimed at a certain valuable goal that constitutes an improvement of the learner. Such improvements are often understood in terms of mental states fostered by the educational process.The shared perspective of both teachers and students is also emphasized by Paulo Freire. In his influential Pedagogy of the Oppressed, he rejects teacher-centered definitions, many of which characterize education using what he refers to as the banking model of education. According to the banking model, students are seen as empty vessels in analogy to piggy banks. It is the role of the teacher to deposit knowledge into the passive students, thereby shaping their character and outlook on the world. Instead, Freire favors a libertarian conception of education. On this view, teachers and students work together in a common activity of posing and solving problems. The goal of this process is to discover a shared and interactive reality, not by consuming ideas created by others but by producing and acting upon one's own ideas. Students and teachers are co-investigators of reality and the role of the teacher is to guide this process by representing the universe instead of merely lecturing about it.
