Purposes of Assessment
Summative
•
•
•
•
•
•
•
•
To pass or fail a student
To grade or rank a student
To license to proceed
To select for future courses
To license to practice
To predict success in future courses
To predict success in employment
To select for future employment
Purposes of Assessment
Formative
• To provide feedback to students to improve their
learning
• To motivate students
• To diagnose a student’s strengths and weaknesses
• To help students develop their skills of selfassessment
• To provide a profile of what a student has learnt
Purposes of Assessment
Evaluative
• To provide feedback to teachers
• To improve teaching
• To evaluate a course’s strengths and
weaknesses
• To make the course appear ‘respectable’ and
credit worthy to other institutions and
employers

Activity: Assessment
Methods
Choose an assessment
method(s) you currently use
and “map” it on to
1) a learning outcome
2) these dimensions.
Do individually, then share at table
Then with whole group
Assessment Methods
(Some Examples)
•
•
•
•
•
•
final exam (written)
Homework
projects
reports
Presentations
observed discussion
groups
• office hours
• final exam (multiple
choice)
• quizzes
• cold calling
• career performance
• standardized tests
• personal response
systems
Higher validity – less reliable
Higher reliability – less validity

What will
students learn?
If they have learned What will students do
it, what will students to learn it?
know and be able
to do?
How will students
demonstrate they
know it or are able
to do it?
Students will
understand the
transfer of
information from
DNA to proteins.
Students will be able
to predict changes in
amino acid sequences
caused by mutations.
On exam students will
predict the new
amino acid sequence
that results from a
mutation in a given
gene sequence.
In groups students are
given sequence of DNA
corresponding to amino
acid sequence. Students
identify reading frame
and predict amino acid
changes due to mutations
in that sequence.

Benefits of Rubrics
 Used for grading (Summative) or feedback
(Formative)
 Clear criteria (Criteria Ref.)
 Ensure grading aligns with learning outcomes
(Validity)
 Shared with multiple teacher graders/situations
(Reliability)
 Can be used with students (Self Ref.) and peers
(Peer Ref.)
Activity
In small group, identify and design
a rubric for a specific Learning
outcome

MCQs as formative instruction
Answer and provide your rationale:
1. Which of the following has/have intrinsic pacemaker
characteristics?
a) Medulla
c) Sinoatrial node
b) Pons
d) Atrioventricular node
Use rationales (short open-ended explanation for choice) to let
students demonstrate their learning - can be graded or not..
Stanford Learning Lab: Nash & Shaeffer, 1999; Schaeffer et al., 1999
Ideal rationale:
SA node is the normal pacemaker for the entire heart. AV node also has pacemaker
potential, but is overshadowed by SA node. Medulla has pacemaker potential for
breathing rhythm as well. Pons helps refine rhythm, but does not have pacemaker
potential.
Less-than-ideal rationales:
Offering an incomplete answer: Normally the SA node is responsible for generating heart
rate, and it is able to do this because of its intrinsic rhythm. The AV node also has an
intrinsic rhythm, but it is “overshadowed” by that of the SA node.
Providing a book definition: The sinoatrial node is the pacemaker of the mammalian
heart.
Providing irrelevant information: Stretch receptors are located in the aortic arch and the
carotid sinus. They have the ability to respond to changes in pressure.
Restating the question: The SA node, AV node, and medulla all possess intrinsic
pacemaker characteristics as they all serve as intrinsic pacemakers.
Blind appeal to authority: This answer is right because Professor Heller said that it was,
and Professor Heller is cool.
Activity
In small group, share other ways in
which the validity of MCQs might
be enhanced.

Testing low-level knowledge
Purely economic loss is recoverable in a product liability action.
a) True
b) False
Purely economic recovery will be barred in which of the
following causes of action?
a) Negligence
b) Fraud
“What’s the rule?”
c) Defamation
No context, not allowing for
d) Product liability
interpretation/analysis
from Case & Donohue, 2008
Revision: Higher-level understanding
A restaurant hired an exterminator to eliminate cockroaches from the
basement under the restaurant. Around midnight, the exterminator
applied to the basement floor and walls an effective pesticide that he had
purchased from the manufacturer. A toxic gas released by the pesticide
penetrated into the restaurant kitchen and did not disperse by the next
day. As a result, the restaurant was required to close that day.
The restaurant brought a tort action based on product liability against the
pesticide manufacturer for lost profits.
Will the restaurant prevail?
a) No, because in this action purely economic loss in not recoverable. *
b) No, because the exterminator was the proximate cause of the restaurant's
damages.
c) Yes, because the manufacture of pesticides is an abnormally dangerous
activity.
d) Yes, because the pesticide was being used as intended.

3 ideas to take with you
Assessment is teaching
Students need to be involved
Assessment gives you no more
than what you ask for
