Incorrect
Which of the following statements is not
a best practice in regard to how teachers think about and plan for assessment?
Teachers start units of instruction on Monday in order to assess them by Friday. Teachers must have a clear understanding about the purpose of the assessments. Teachers reflect on why they are assessing the students in the first place. Teachers carefully plan for how the assessment activity will contribute to increasing student achievement.

Question 2
What is an example of a formative assessment that teachers can use to adjust future instruction?
having students answer the review questions at the end of the chapter using paper and pencil using prepackaged assessment materials from the Teachers Pay Teachers online store and having students check their partner’s papers giving pop quizzes at the beginning of the lesson but not grading them spot checking within lessons, reviewing assignments, monitoring work 4 / 4 pts
Question 3
No pass, no play and high-stakes testing are two different examples of assessments being given for the purpose of sorting students. If students show
proficiency, they are allowed to participate and/or are promoted to the next level.
True False 4 / 4 pts
Question 4
What is the difference between a norm-referenced exam and a criterion-referenced exam?
Criterion-referenced tests measure a student’s progress toward mastery of a standard, but norm-referenced tests compare a child’s mastery level to that of his or her
peers.
Teachers prefer norm-referenced exams to criterion-referenced exams because scores are reported on a bell curve and they can easily record the results in their
grade books.
There is no actual difference between the exams because they are both high-stakes exams. Criterion-referenced tests compare student scores, but norm-referenced tests measure a student’s progress toward mastery.

Question 9
Incorrect
Incorrect
The results of a teacher-made test would easily fit the normal curve profile because the goal of instruction is that half the class scores satisfactory or better.
True False 0 / 4 pts
Question 10
Incorrect
Incorrect
Student test scores actually have very little meaning until an assessor interprets the score, considers the special needs of the learner, and uses that
information to plan for the next steps of instruction.
No, test score data can stand alone and are often shared publicly as accountability for school districts in local newspapers as raw data. Yes, this is typically done by district testing coordinators, and the data are returned to teachers at the beginning of the following school year. Yes, there are many variables to consider when using assessment to adjust instruction for student growth. No, the assessor needs only to plan the instruction for student growth. He or she doesn’t have to do anything with the test data to figure out what the student knows.

Question 11
Incorrect
Incorrect
One disadvantage of a criterion-referenced test is that it does not allow you to compare the student’s achievement to that of his or her peers but shows only
how well that student reached a defined level of performance. It’s hard to truly gauge a student’s performance without comparison or competition.
True False 4 / 4 pts
Question 12
When teachers use formative assessments to make adjustments to instruction, the first step is for them to ______.
assign reading to build students’ background knowledge review the desired learning outcomes write rubrics for the assessments they will give plot scores from the pretest on a normal curve 0 / 4 pts
Question 13
Incorrect
Incorrect

Classroom climate shift involves a change in learning expectations for students, student responsibility for learning, and the perceived role of classroom
assessment. To make the successful transition from a traditional climate to a formative assessment climate, all the following factors must be present except
which of the following?
There must be trust between the teacher and the students, and this takes time to develop. The teacher must display true leadership skills. The teacher must be friends with his or her students. There has to be a social construction by the teacher and the students. 4 / 4 pts
Question 15
What is the term used to describe the process of determining whether a student is ready to move to the next level of learning?
Individual assessment Formative evaluation Summative evaluation Diagnostic assessment 4 / 4 pts
Question 16
When Mr. Woodson is using assessment data to determine which of his students he will promote to the ninth-grade center, what should his first thought be?
I will use high-stakes testing data as the sole measure. I will use no pass, no play rules. I will use summative evaluations such as EOI (end of instruction) scores solely. I will use multiple assessments to get a thorough picture of what my students can do.

Incorrect
Incorrect
How would a teacher check to see if a test she wrote for her eighth-grade science class was reliable?
She would check to make sure each of the items on the test actually related to the standards she taught. After she gave and scored the exams, she would check to see if the scores were similar between her six science classes. She would check with the other eighth-grade science teachers to see if the scores on the tests they wrote for their classes were similar to the scores of her own
students.

Question 20
Mrs. Patton’s top-performing student in eighth grade showed up tardy on the first day of high-stakes testing and had tears streaming down her face. She told
Mrs. Patton that their beloved dog had passed away in his sleep that night. Mrs. Patton felt empathetic toward the student, but she was also upset. Why do
you think Mrs. Patton is upset?
Now the test conditions will not be consistent for all test takers. Mrs. Patton knows this student will not be able to make a maximum effort in her time of grief. Mrs. Patton’s pay is tied to those scores and she needs them to be as high as possible, and now her top student is letting her down. The top student is late, which means she’ll have to reread the test booklet directions all over again. 4 / 4 pts
Question 21
Tina is a first-year teacher with many questions about assessment for her mentor teacher, John. Which of the following questions is least pressing for a new
teacher?
What methods do you recommend I use to assess student work? How do you use information about students’ current level of understanding to adjust your instruction? Should students use trifold folders around the perimeter of their desks to deter cheating? What methods do teachers on our team use to determine grades and prepare report cards? 4 / 4 pts
Question 22
Mr. Sorenson understands the reason he needs to assess his students with an exam and has purposely designed the instrument to meet the needs of his

Question 23
Damion has given a pretest to determine what his students already know about ecosystems. He planned lesson activities based on those pretest results but
is now in the middle of his lesson and is receiving lots of blank stares and questions from his students. This type of feedback indicates to Damion that he
needs to ______.
complain to other faculty and staff about how slow his class is in the teacher’s lounge during his plan time continue teaching because he has a lot of material to cover stop the lesson, go back and review some prelesson key concepts by asking key questions, and try modeling the concept using another method not teach anything else about ecosystems at this time because the students are not ready for this information 4 / 4 pts

Solving for a reactant in solution
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride
anions in solution will combine with the silver cations to produce bright white silver chloride precipitate.
Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with tin(II) chloride, which would react with silver nitrate solution
like this:
SnCl,(aq) + 2 AgNO,(aq) → 2 AgCl(s) +
Sn(NO,),(aq)
The chemist adds 23.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he
has collected

A chemist v v
as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of
pentane, dimethyl sulfoxide, acetone, methyl acetate, and chloroform.
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety
Data Sheets (MSDS), the chemist finds the following information:
liquid
density
0.63
mL
pentane
db
dimethyl sulfoxide
1.1
0.79
acetone
0.93
mL
methyl acetate
1.5
chloroform
