also plays various critical roles, such as providing feedback on the learning progress both to the student, their parents, and their teachers. Concrete discussions on the role of testing often focus less on whether it should be done at all and more on how much importance should be ascribed to the test results. This also includes questions about the form of testing, for example, whether it should be standardized. Standardized tests present the same questions and scoring system to all students taking the test and are often motivated by a desire for objective and fair evaluations both of students and schools. Opponents have argued that this approach tends to favor certain social groups over others and severely limits the creativity and effectiveness of teachers. Philosophical movements Existentialist The existentialist sees the world as one's personal subjectivity, where goodness, truth, and reality are individually defined. Reality is a world of existing, truth subjectively chosen, and goodness a matter of freedom. The subject matter of existentialist classrooms should be a matter of personal choice. Teachers view the individual as an entity within a social context in which the learner must confront others' views to clarify his or her own. Character development emphasizes individual responsibility for decisions. Real answers come from within the individual, not from outside authority. Examining life through authentic thinking involves students in genuine learning experiences. Existentialists are opposed to thinking about students as objects to be measured, tracked, or standardized. Such educators want the educational experience to focus on creating opportunities for self-direction and self-actualization. They start with the student, rather than on curriculum content. Perennialism Perennialists believe that one should teach the things that one deems to be of everlasting importance to all people everywhere. They believe that the most important topics develop a person. Since details of fact change constantly, these cannot be the most important. Therefore, one should teach principles, not facts.

Since people are people first, and workers second if at all, one should teach liberal topics first, not vocational topics. The focus is primarily on teaching reasoning and wisdom rather than facts, the liberal arts rather than vocational training. Classical education The Classical education movement advocates a form of education based in the traditions of Western culture, with a particular focus on education as understood and taught in the Middle
