The term "thesis statement" applies to very short, formulaic essays by students, in which one or two sentences in the first paragraph of the essay set forth the writer's thesis and thus form a "thesis statement". Although longer and more sophisticated works have a "thesis" in the sense of a stance or point of view, in general, they do not possess a "thesis statement", as their ideas are longer and more complex than can be encapsulated in one or two sentences.
The "banking model" of education acts as Paulo Freire's bête noire in Pedagogy of the Oppressed, the model of bad capitalist education, and associated with the evils of banking, which Freire also sees as an emblem of capitalist oppression. It should be noted that no system of education describes itself as a "banking model"; this term was created by Friere to describe systems he opposed, and thus forms somewhat of a straw man.
For Freire, critical pedagogy is the polar opposite of the "banking model", and involves the learning thinking critically about material as opposed to simply memorizing it. Much of Friere's opposition to educational "banking" has to do with the Marxist notion of bourgeois ideology and the need for critique thereof; critical pedagogy and opposition to "banking" is thus firmly embedded in the notion of radical critique of false ideology.
