According to Realism, reality is learned by man by observing the natural world. For the essentialist teacher, the student should do more than simply read the textbook; the teacher could cement the concepts in the student's mind with some projects. In particular, this would be true in the science classroom. The law of gravity, for example, could be taught through a lecture by the teacher, and the student could then better grasp the concept by performing an experiment prepared by the teacher. The essentialist classroom has some utility for activities and experiments when teaching students. However, students would still rely on the teacher to determine what the project and experiment would be. In contrast, idealism believes that the reality of the universe is found in ideas. This causes the idealist to place emphasis on texts that have stood the test of time. For the essentialist teacher there would be a strong emphasis on certain classics to teach moral truths. While an essentialist may not recognize the inerrancy of Scripture, he or she may encourage his or her students to read Bible stories for their moral value. The essentialist, for example, can encourage the student to learn the lesson of the “Good Samaritan” to teach him to love others. While this places the Bible as another good book to read, it helps the teacher present the right moral values.
