Pre-assessment Review

This document is designed to be used after you have taken the pre-assessment
and as you prepare for the final objective assessment. It focuses on specific
items on the pre-assessment and is not designed to
replace a general review of modules.
Metacognition--thinking about thinking
(Click here for a short video.) As you
,work through this document, you will increase your learning by:
● Before reading the explanation, rework the problem, and ask
yourself:
○ What type of question is this? (For example: standard deviation,
interpreting the slope…)
○ What key words helped you identify the type of question?
○ What information is needed to answer the question?
○ Work the question. Underline key words and show your steps.
● Now, check your answers and explanations. Ask yourself:
○ Why did you miss this question? For example:
■ Was it a careless error?
■ Did you know all the terms?
■ Did you forget a step?
○ Do your steps line up with the short answer explanation?
○ How can you apply this to future questions?
● Watch the recommended video.
○ Pause the video and work the problems ahead of the instructor.
○ Ask the same questions you asked yourself when
reworking the preassessment problem.
● Quiz yourself on what you learned. Can you remember the key
parts of this problem and work it correctly when you redo it later
today or tomorrow?
These questions help you identify your process to do a question and
help you to do similar problems on the assessment. You are thinking
about your own thinking!
