Entry #2

"Relational Understanding and Instrumental Understanding" by Richard R. Skemp is an article discussing two different types of mathematics teaching. Skemp explains that relational understanding is what most of us would consider to be a true understanding. An understanding where the process of what to do, and the reason why it is to be done that way, are clearly understood. Skemp describes instrumental understanding as being a lesser understanding of the concept. He states that instrumental understanding is not knowing why you are doing something but just being able to apply a formula. The two might be thought of as follows, relational is understanding why you are doing what you are, and instrumental is being able to "plug and chug" when given a formula. Skemp presents three reasons why instrumental understanding might be advantageous and consequently some disadvantages to relational understanding. The first reason is that instrumental mathematics can be much simpler to understand than relational. He says that understanding some concepts relationally can be too complicated for pupils when it is initially presented to them. When a concept is simply too complicated to be taught relationally, instrumental instruction is beneficial. Another reason Skemp proposes that instrumental mathematics can be better is that it allows students to reach the correct answer quickly, rather than having to work their way through it. The final reason that instrumental can be beneficial is that it provides what we would call "instant gratification." Students get a page of right answers, feel successful and then are motivated to continue. Skemp states many times in his article that he is biased towards relationally understanding, he lists four reasons why relational mathematics is superior to instrumental mathematics. The first point he raises is that a relational understanding of a concept allows the pupil to apply the process to more abstract ideas and can thus succeed at a wider range of problems, whereas the student who has only an instrumental understanding would only receive frustration when he attempts a new type of problem. He then tells us that even though instrumental understanding is easier to learn than relational it is not easier to remember. Relational becomes superior in Skemp's opinion because there are no rules to be memorized just concepts to understand and then the rules can be derived. When talking about instrumental understanding Skemp noted that it could be beneficial because it provides instant gratification, on a similar note, Skemp tells us that even though it may take longer to do a problem with relational mathematics, learning it relationally acts as the goal itself and the need for outside motivation is reduced. His final reason for superiority is closely related to his previous argument about motivation. When the learning itself becomes the goal, the motivation is applied to learning more and more and even branching out of the limits of the classroom, leading to a more dedicated and interested pupil. When it comes to the actual application of these two types of mathematics, it is fairly common that mathematics will be taught from a strictly instrumental stance. Instructors will not even attempt to give an answer to the question of why something is performed a certain way. Relational understanding on the other hand usually encompass mostly concepts and understanding but it is likely that formulas will be introduced and used which come from instrumental mathematics. Skemp is strongly in favor of relational mathematics but is aware of the system and the difficulties that prevent relational instruction from occuring.

  1. I think your depiction of the advantages of each type of understanding is very thorough. I also like your discussion of how the two types of understanding typically show up in the public schools.

    In response to the first sentence of your paragraph, I think of instrumental and relational being terms to describe primarily two different types of understanding, rather than two different types of instruction. In other words, there may be multiple ways of teaching for either type of understanding. Some people in the field do talk about teaching for relational understanding, but typically they don't use the term "relational teaching."

    Although I asked you to present all of the ideas in a single paragraph, I think there may have too much information in the entry to fit comfortably into one paragraph. In fact, I think there might be four different topics sentences in the paragraph, which suggests that maybe the information would be better expressed in four paragraphs instead of one. Of course, that's not what I asked for. So it's probably my fault that this paragraph is a little overloaded in terms of content.

  2. I really liked how you compared the two. Your organization was layed out very well. You really did a good job at discussing both the advantages and disadvantages. You put in a lot of infomation, which was good, but I would have tried to make it a little more brief. The length of the paragraph was a little intimidating. Altogether you did a really good job and I enjoyed your look at the article.

  3. I agree with the facts that you gave about Relational and Instrumental understanding. I think that you presented the ideas of Dr. Skemp very well, especially Skemp's views on the advantages and disadvantages of the two different types of understanding. However, I also agree with Dr. Siebert, in the fact that your single paragraph could have easily made up a few paragraphs. I believe this would have helped the flow of your article a lot better, by splitting up the paragraph a little more. Great job!

  4. Great write up. Your paragraph is very well-written. I feel like you gave me enough information that I do not even need to read the article. The comparison was accurate and complete. The only thing I could think to change is to make it a little shorter.
    well done!

  5. I really enjoyed reading your summary of Skemp's article. I felt like you hit all of the major points and clearly explained them. The only thing i would change would be the overall explanations of each type of understanding. That might just be the case because I understand the material from the article without further explanation, but a more compacted summary would have been easier to read.
