Major Learning Taxonomies
1- SOLO, Structure of Observed Learning Outcomes
Biggs & Collis 1982
2- Bloom’s Taxonomy of Learning Domains
cognitive (knowledge)
affective (attitudes)
psychomotor (skills)
Bloom & Krathwohl 1956
The SOLO model consists of 5 levels of understanding
•
•
•
•
•
Prestructural – the student acquires bits of unconnected
information that have no organisation and make no sense.
Unistructural – students make simple and obvious
connections between pieces of information
Multistructural – a number of connections are made, but not
the meta-connections between them
Relational – the students sees the significance of how the
various pieces of information relate to one another
Extended abstract – at this level students can make
connections beyond the scope of the problem or question, to
generalise or transfer learning into a new situation
Unistructural questions
To answer the question
students need the knowledge
or use of only one piece of
student
given information, fact, or
idea, that they can get directly
from the problem.

Using the SOLO Taxonomy
solo-taxonomy-1204838403126960-5.ppt
Multistructural questions
Students need to know or
use more than one piece of
given information, fact, or
student
idea, to answer the
question, but do not
integrate the ideas.
This is fundamentally an
unsorted, unorganised list.
Facts
Response
Relational questions
These questions require
students to integrate
more than one piece of
given knowledge,
student
information, fact, or
idea.
At least two separate
ideas are required that,
working together, will
solve the problem.
Facts
Response
Extended abstract questions
These questions involve a
higher level of abstraction.
The items require the
student
student to go beyond the
given information,
knowledge, information, or
ideas and to deduce a more
general rule or proof that
applies to all cases.

GRAPHING
Identify the parts of graphs and recognize different types
of graphs (e.g., identify the X axis, identify a histogram)
Describe the data represented in a simple graph
Draw a graph based on a given set of data; predict
outcomes based on data presented in graph
Read and interpret a complex graph having multiple
variables or treatments and explain biological
implications of data
Create a graphical representation of a given biological
process or concept
Assess the relative effectiveness of different graphical
representations of the same data or biological concept

How to Bloom a test?
Ask a colleague
Buy them coffee
Have them “Bloom” your exam
Physiology: Cardiac Output (MP Wenderoth)
Cell Biology: Nuclear transport (Alison Crowe)
Immunology: Virology (Clarissa Dirks)
Crowe, Dirks & Wenderoth 2008. CBE- Life Science Education 7:368.
Physiology: cardiac output
Knowledge-Recall
Which two variables determine cardiac output for an animal?
Comprehension-Understanding
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.
Crowe, Dirks & Wenderoth 2008. CBE- Life Science Education 7:368.
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?

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)
“To achieve these ambitious goals,
we will need much more emphasis on
both science education and the
“science of education”.
