At the beginning of the 20th century, American educator Dewey put forward the question-based pedagogy and made it a point of reference to the theory of education that “students should acquire knowledge and skills in formulating problem-solving problems.” In the late 1950s, Brunell, a famous psychologist and pedagogicist, proposed that the core of discovering pedagogy is also to revolve around the issue of advocating for students to discover on their own, and this finding is based on the foundations on which teachers create situations conducive to spotting problems Above.

Experienced teachers in the teaching process, always carefully designed to ask
