“Correction Reflections” Often times when a student makes a mistake in a mathematics problem he/she realizes, after the fact, that he/she made a careless error in computation. Other times, the student may think he/she made a careless error but in reality he/she may have serious misunderstandings regarding a particular concept. As a facilitator of learning, a very effective way to assess a student’s understanding is by hearing his/her problem solving process. Because of time constraints and because of the often times shy nature of students, it becomes a daunting task to pull from each and every student his/her thinking processes. An assessment tool that helps to accomplish the task is an error analysis process called “ Correction Reflections “ Outline of an acceptable “Correction Reflection” I. “Correction Reflections” are composed of two different languages; Symbolic (mathematical) language and Written/Verbal (English) language. a. Symbolically: Students must show detailed new work for each missed problem. Final new answer must be highlighted or circled. b. Writing: Each revised problem must be supported by a written proof statement. This statement must convince the instructor that the student has reviewed, analyzed, and assessed his/her own errors in the problem solving process. Proof of understanding is demonstrated by following some or all of the following guidelines: 1. Using mathematics vocabulary state a rule, theorem, definition, etc. (from your textbook) that applies to the error you made. • Example: If you incorrectly place a negative sign in an answer, after reworking the problem correctly you would state the rule of signed numbers that would support your correct answer. • Your original work: -3 – (-2) = -5 is incorrect. Your revision: -3 – (-2) = -3 + 2 = -1 is correct. My proof of understanding statement would be “I recall that the Definition of Subtraction is addition of the opposite. Thus, the subtraction sign changes to addition and –2 becomes it’s opposite which is 2. Then, –3 + 2 follows the rule for addition of unlike signed numbers which states that you must subtract the two numbers and assign the answer the same sign as the largest number (in absolute value) in the sum.” (Continued on p. 2) P.2 2. Never use the following as proof statements: (each is followed by what goes on in your instructor’s head when he/she reads such statements.) • “I messed up because I put the wrong sign.” (DUH!) • “I made a stupid mistake” (You will continue to make stupid mistakes unless you do your correction reflections well) • “I rushed.” (Obviously, you still are!!) • “I ran out of time.” (Now, you have plenty of time to do this correction reflection) • “I don’t know what I did wrong.” (Why didn’t you ask others or me, refer to the book, worksheets, other student’s work, lab (6331) tutors, videotaped lectures, Internet tutorial resources, or the president of the United States in order to gain understanding.) “Correction Reflections,” when done effectively, will dramatically increase your understanding and future mathematics success as well as your overall problem solving skills in life. If you choose not to use this powerful tool you will be penalized as follows: • Quiz grade of Zero if you did not achieve a perfect score and did not write your correction reflections. • 10% deduction in your Test Grade if you did not complete correction reflections for all errors. Hints: • You can get help from anywhere or anyone in order to do correction reflections. There is no excuse for continuing to not understand. • The instructor will often work out the problem for students and give them the correct answers. Thus, the importance of the written proof should be obvious. Simply copying the instructor’s work or the correct answer does the student no service and proves nothing to the instructor of a students understanding. • More time spent on reading, studying, working problems, and reviewing prior to a test or quiz is directly proportional to less work doing correction reflections. When assessing “correction reflections,” the instructor is judge and the student is attorney. The student must prove to the instructor, beyond a reasonable doubt, that his/her understanding (client) is clear (innocent). Would an attorney ever plead that his client is not guilty because he/she didn’t do it? Ask yourself this after each of your corrections. “Did I represent my knowledge with my words sufficiently to prove my understanding to my instructor?”
