Developing Formative Assessments
Sarah Ades
Penn State University
workshop learning objectives (outcomes):
At the end of this workshop scholars will be able to:
• Describe the role of formative assessment in learning.
• Explain why assessments should be aligned to learning
objectives and outcomes.
• Evaluate different types of assessment activities to find
those that are aligned best with the learner’s abilities and
level of understanding to be assessed.
• Develop aligned assessment activities to provide evidence
of learning to both the instructor and learner.
I am a junior majoring in biology. I usually get A’s in my courses; only a few B’s
so far in college. I totally breezed through high school. It was so easy. I’m think that
I might go to graduate school or medical school.
This semester, I enrolled in introductory microbiology. I approach this class like
most others—I attend lecture (have only missed two this semester!), read the
textbook (usually before class, if I have time), and turn in the homework if it’s going
to be graded. Prof. Lopez is great; he’s really well organized and follows the book
closely. The homework has been helpful for learning the terms and information.
The first midterm exam in this course was NOT what I expected. None of the
questions were multiple choice. Instead, we had to write out short (and sometimes
LONG) answers. I barely finished it in the 2-hour exam period. Plus, three of the
questions tested us on things we never learned and skipped stuff we had covered in
class. For example, we learned about a specific example of the lac operon in class
last week. I worked really hard to memorize all the important steps in the process,
and then it wasn’t even on the test. But there was this question about asking us to
“describe a strategy that bacteria use to regulate gene expression and explain why
such a strategy might have been selected for over time.” How am I supposed to
know about that? I got a 72% on that test. What a crock!

Assessment
What is assessment?
A method to determine whether of not students learned (or accomplished) the
learning objective.
Evaluate and determine if the students are learning what they are supposed to
learn.
Measuring student learning.
Assessment is how we monitor student's ability to learn.
No real idea to be honest.
A method or means of measuring learning.
A way of determining what students actually understand and at what level they
understand.
To find out if what you think you are teaching them is what they are learning.
Assessment is a process of measuring how effectively a course or program
accomplishes its goals.
A tool that is used to measure how well students have met the learning goals the
educator has defined. It can also provide information to the educator about the
effectiveness of their teaching methods.
Tools used to measure student understanding and inform teaching practices.
A way of evaluating effectiveness of teaching and learning.

Assessment
What is role of assessment in teaching and learning?
It gives instructors a way to monitor student learning.
Helps us to understand where the problem is and figure out how to improve teaching and learning.
To assure that students are learning what we intend them to be learning in the course.
Assessment is used to plan, implement, and modify courses.
It is how I know that students have learned a concept or idea. Not only how they have learned but at
what level they are learning it.
To gauge student learning for give formative feedback to help students in the learning process or to
determine final learning gains using a summative instrument.
If done correctly it should guide teaching and learning both.
To find out if you are being successful in your teaching, and to show the student where their
misconceptions are.
Teaching strategies can be modified based on the results of assessment to improve learning
outcomes.
A consistent and defined way of improve teaching (iterative process of assessment, adaptation of
practices, repeat).
Assessment should be aligned with learning outcomes and should help us identify whether or not
we've taught the materials effectively. It should include lots of low-stakes practice (formative
assessment) and culminate in summative assessment(s).
In the formative form it is to inform teaching and learning. What do I (my students) know and what
do we need to work on. In the summative form it informs instructors and students about level of
knowledge.

Assessment?
 Assessment a way of providing students and teachers with
information regarding students' progress towards achieving
the learning objectives. Evidence.
 The role of assessment in teaching and learning is to provide
feedback to both the teacher and the student. It allows
teachers to tell whether their teaching methods have been
effective or whether they need to re-teach a particular
concept. On the other hand, it allows students to identify
misconceptions and gaps relating to the new content being
learned. It also allows students to identify if they are studying
effectively.

• According to Donald Rumsfeld: “There are known knowns. There are
things we know that we know. There are known unknowns. That is
to say, there are things that we now know we don't know. But there
are also unknown unknowns. There are things we do not know we
don't know.”

Experiment 3: Bacterial Behavior- Motility and Chemotaxis
One of the distinguishing characteristics of animals is their ability to move in response to stimuli that originate from
within their own bodies or from the outside world. Many of us are attracted to the smell of fresh-baked chocolate
chip cookies and repelled by the aroma of a recently antagonized skunk. An animal moving rapidly toward an
object it recognizes as food or fleeing a harmful chemical are examples from the repertoire of responses known as
animal behavior. Even the simplest and smallest animals exhibit behaviors within their own sensory capabilities…
Resources
You can find basic information about flagella and chemotaxis in any microbiology textbook.
Online resource with an overview of bacterial motility, flagella, and taxis:
http://textbookofbacteriology.net/structure_2.html
Key concept
Bacteria behave in response to stimuli.
Challenge
We will use two different assays to determine if your pets are motile and chemotactic . We will also provide you
with a plate of swimming E. coli and an assay to determine if a substance is an attractant or a repellent. Develop a
hypothesis about E. coli’s responses to different compounds- we will provide you with some sugars and amino
acids. You are also welcome to bring in other substances that you would like to test.
Key Questions
• What advantages does chemotaxis provide for a bacterium?
• High concentrations of repellents increase the tumbling time of E. coli. How does this help the bacteria move
away from the repellent?
• Different bacteria chemotax towards different chemicals. Why might this be?
• Some bacteria are not motile. What factors in their environment might allow them to flourish without selfpropelled motility?
• Penicillium notatum is not motile. However, it spreads over the surface of a petri dish and can even spread
from one piece of bread to another. How might either of these behaviors occur in the absence of self-propelled
motility?

Motivational methods:
• Relate experiments to real world
• Give students ownership of experiments
• Treat students like scientists
Formative assessments:
• Pre-class quizzes (3 tries)
• In class activities - design experiments, analyze data (own and from literature)
• Notebook checks
• Informal questions while circulating in class
• Students can repeat some activities until they master them
Summative assessments:
• Lab reports (graded by rubric), rewriting allowed
• Key questions – apply learning
• No lab practicums – must master methods to identify and keep pet alive
• Oral reports

understood why and what we were doing not just to make sure we followed a procedure correctly.
This course built on the material we learned in the beginning and continued to build on it, which personally helped me retain the
information more than just about every course I have ever taken.
The student query aspect of the course allowed me to learn that most that I possibly could have from MICRO 202. I really enjoyed
asking my own questions for each experiment and feeling as though I had autonomy to set up the experiment as I saw fit to answer my
questions. I believe that the set-up of this course allowed me to become a more confident science student and that I now have more of a
sense of how to work in lab setting--it is now common sense to me to start with a hypothesis, to figure out what controls to set up to
make sure that I can distinguish true results from inconclusive data...I don''t think I could have done that nearly as well without this
course.
