However, if the students are told the reason behind acquiring certain knowledge, chances are high that they will perform better in their exams. Dewey observes that past knowledge should be stored and taught if the circumstances that led to it are met in the future. This approach may be problematic because such future may never occur because in the world things are changing very fast.
This is the reason why this approach cannot hold water and students are still taught things that are unhelpful in their circumstances (Violas, Tozer & Senese, 1999).
Consequently, Dewey notes it as wastage of time by teaching students things that are impractical in their current circumstances. This is denying the students the freedom to choose what best suits their situations. Educators, should however, develop their lessons based on the current state of affairs of the students.
