I have experienced Tyler’s rational in schooling through many of my classes from k-12 where teachers taught what to think rather than how to think. They taught us facts and knowledge to be memorized and later tested, and neglected to promote critical thinking. As well I’ve had teachers who let their personal opinions and views get in the way of how they treated the students who disagreed and how they taught their lessons in a bias way.
Some of the limitations in Tyler’s rational is the room for creativity and expression, as well as personal, world view growth. It is also limited by the fact that people behave differently, react differently, and learn differently and so to measure these things in such an objectified way is difficult. It also makes it easy for students and teachers alike to overlook learning that is naturally happening within the classroom and its interactions rather than engaging in that social learning and applying it to the lesson.
Tyler’s rational makes it easier to organize the curriculum and units in a way that can measure the written content. It provides a tangible testable way to grade and determine the knowledge acquired from the class over the year/ semester.
