II. Circle the NCTM Standards practiced
during this tutoring session. 
Then, explain how you met those standards
below.
1. Problem-Solving
2. Reasoning and
Proof
3. Communication
4. Connections
5. Representation
6. Use technology
III. Artifact
Briefly describe the focus of your tutoring session.
My pre-calculus tutee needed help with conceptualizing log functions as inverses of exponential functions.
We calculated several problems using logarithm calculations where inverse relations helped solve the
problem.
Example: Solve 2.3 = 10x+1
IV. Reflection
1. At the end of your session, ask your tutee the following questions. Then ask yourself the same questions.
Briefly note both yours and your tutee’s responses.
1. What went well during this tutoring session?
2. What could have improved this tutoring session?
Tutee Responses
1. I was able to see how logs “cancel”
Exponents.
2. I was a bit fuzzy on the inverse function
Concept.
Tutor Responses
She could do the inverse problems on her own at the end.
She confuses composition of inverse functions with
Multiplicative inverses equaling 1.
2. Precisely and accurately describe how you met the NCTM standard(s) in this tutoring session. Use the NCTM
Standards Rubric (on back) to guide you.
At the end of the session, my tutee was able to verbally reason through log and exponentials to solve inverse
problems when the base was new to her, thus demonstrating her ability to conjecture, generalize, and reason
through inverse arguments with logs and exponents.
V. Self-evaluation: Briefly, what did you learn from this tutoring session?
The inverse function concept is a more subtle idea than mechanically employing inverses to solve problems.
Next time I will try to make the idea of composing inverse functions to get the identity function more clear.
NCTM Process Standards Rubric
Instructional programs from prekindergarten through grade 12 should enable all students to—

apply and adapt a variety of appropriate strategies to solve problems;
monitor and reflect on the process of mathematical problem solving.
2. Reason and Prove




recognize reasoning and proof as fundamental aspects of mathematics;
