Three major findings:
1. Address student’s preconceptions.
2. Build BOTH a deep foundation of factual knowledge
& strong conceptual framework.
3. Enhance student’s ability to monitor their learning.
(metacognition)
3. How Bloom’s Taxonomy of Learning
& Blooming Biology Tool can
1- Take the mystery out of learning for students
2- Enhance student metacognition
3- Help YOU align your teaching and testing
7. How the Blooming Biology Tool was created
Colleague’s (Scott Freeman) query
Does the MCAT hinder efforts to introduce
critical thinking into Introductory Biology courses?
•Team of 3 faculty
(Alison Crowe, Clarissa Dirks, MP Wenderoth)
•Design a rubric based on Bloom’s Taxonomy
•Rank 700 exam questions

11. Physiology: cardiac output
Knowledge
Which two variables determine cardiac output for an animal?
Comprehension
Define cardiac output and why it is significant.
Application
Lance Armstrong has a normal resting cardiac output 6L/min yet his
resting heart rate is only 40 beats/min. What is his stroke volume?
Analysis
Compared to a normal resting male of the same height and weight, Lance
Armstrong’s stroke volume is greatly increased. Provide a physiological
explanation for a large stroke volume.
12. Synthesis
Create a summary sheet that is a pictorial depiction/ flow
diagram of how changes in cardiac output influence mean
arterial blood pressure.
Evaluation
If an enlarged heart was observed on a CT scan of patient,
how would you determine if this enlarged heart was
pathological or not?
14. Bloom’s level GRAPHING
Knowledge Identify the parts of graphs and recognize different types
of graphs (e.g., identify the X axis, identify a histogram)
Comprehension Describe the data represented in a simple graph
Application Draw a graph based on a given set of data; predict
outcomes based on data presented in graph
Analysis Read and interpret a complex graph having multiple
variables or treatments and explain biological
implications of data
Synthesis Create a graphical representation of a given biological
process or concept
Evaluation Assess the relative effectiveness of different graphical
representations of the same data or biological concept
17. How we “Bloom” a question.

Armstrong’s stroke volume is greatly increased. Provide a physiological
explanation for a large stroke volume.

32. PRE- Bloom’s “But I studied so hard!”
POST- Bloom’s “I need help with analysis level questions”
33. “I remember initially thinking, “Why are we wasting
valuable class time on Bloom's taxonomy?” I felt that
Bloom's taxonomy was a burden, but I now use Bloom's
taxonomy unconsciously to attack many problems. It is a
method used to help organize my thoughts before I act.”
34. Recap
1 - Introduce Bloom’s FIRST day of class
2 - “Bloom” in-class questions ( for practice)
3 - “Bloom” old exam ( to set expectations)
4 -”Bloom” new exams ( to check my alignment)
5 - Show “Bloom” distribution of exam performance
6 - Provide individual “Bloom”exam performance scores
7 - Give students BlAST- learning guide
35. CAUTIONS
1.Do not have students “Bloom” exam during
exam– takes too much time
2.Best to work as a team when Blooming
questions ( for you and your students)
3.Don’t worry about “splitting hairs” on
application vs analysis level questions.
