Study Guide for Test 2 Fall 2010
; on Scantron (I will supply the scantron sheets)
; 50 questions, in multiple choice, T/F, or possibly matching questions
; Bring a #2 pencil
Lectures/Chapters covered: Lectures 6-10 (Chapters 4 and 5).
Source of questions: The test will come from
; the Lecture Outline Notes, based on the in-class questions in this document. As explained in
class, the in-class questions will be changed for the text (from true to false, etc. but they reflect
precisely the terms and concepts you should know)
; the “on your own” questions. At least one question from each of these will be on the test.
; the “not in text” - the RED notes you took in class. From 5 to 10 questions will come from
; Study/read over your class notes. For some students it will be helpful to review the same
concepts in the textbook – the visuals are a good reminder of concepts covered.
; Then look at the questions below and see if you can answer them. Do you know why a statement
isn’t true? Do you precisely the definition of a term? Remember, the definition for one term,
such as elevation, may be used in a T/F paired wrongly with the definition of another term, such
as Often I will take a group of T/F questions in the notes and turn them into a multiple choice
question, changing the items that were true or false. Often a multiple choice question will ask
“Which is FALSE?” Therefore you must understand the material in the questions, don’t just
memorize the answers to the questions the way they are, because true statement will be
changed to false, etc. For example, if the answer is C in a multiple choice question in the
notes, another answer will be correct on the test.
On your own (answers not in the lecture notes; look them up in the textbook)
