When it comes to education and retention, there are four noted levels of comprehension. The four levels are Literal, which is what is actually stated, Interpretive or Inferential, which is what is implied, Applied or Evaluative, which is when what was meant by what was stated is actually applied to concepts or ideas that go beyond what was discussed, and the final level, Appreciative, which is
. more abstract and based on a deeper understanding of the material in question.The first level, which is the Literal level, is based on what was actually stated in the material. It is the easiest because it deals with the facts that were presented, nothing more. In this level, there is no need to go beyond what was stated, the material just has to get absorbed as it was shared, with no bias or opinion by the reader or student. For the most part, as long as the person understood the material, the language of it, what was viewed, than it is safe to say that they achieved the literal level of comprehension.The second level, Interpretive or Inferential, depending on the theorist in question, goes a step further. This level requires that the subject material is not only understood, but also that a general understanding of what was implied is reached. This forces the student to build his or her understanding of the subject matter by using the facts presented to read between the lines for the true meaning of what was meant for absorption.The third level, Applied or Evaluative, is the level that deals with the student applying what was shared to real life events or situations. This level does allow for the student or reader to include bias and their opinion as it relates to the subject material. Their ability to translate its meaning to their own experiences is the measure by which their level of actual understanding is based, so far as their retention goes.The final level, Appreciative, is based on the student's own feelings towards the material or author. It is considered more abstract than any of the other levels because personality, likes and dislikes can affect this level. Inevitably, the key is to get each student to go through all four levels of comprehension, and this is a good guide to follow to gauge if the levels are indeed reached by the student.
