Transcript of Decision-driven learning
School of Medical Sciences
University of Aberdeen
The use of QuestionMark to deliver "decision-driven" learning
Dr. Steve Tucker
.......laboratory technique for detecting
one of the most commonly used laboratory techniques
uses antibodies, to specifically detect protein of interest
...who needs to know about Western blots
~40% of Medical Science students go on to do research
very strong possibility that they will encounter Western blots
Use of QuestionMarkPerception (online assessment tool)
The Decision Engine.........
How do we teach about Western blotting?
Lectures on theory
Some limited practical demonstrations
Clearly, practical "hands-on" experience is desirable
- large classes
- complex multistage technique
- time constraints
- technically challenging
To design an interactive tool to enrich student experience of Western blotting
To represent the protocol as a series of connected decisions each with consequences presented in the form of feedback
Enhanced student understanding of this fundamental technique
Reinforcement of correct principles, avoidance of mistakes
Safe, low cost, interactive experience of Western blotting
Map WB protocol out as a series of decisions
Design this as a series of questions that lead student through the protocol
Answers to the questions will determine student progress through the experiment
Will also influence quality of result at the end of the experiment
Students learn interactively about practical aspects through this process
Use in lectures/tutorials
Structure like a dry practical session
Embed in practical courses
Feedback suggests UG and MSc students, their project supervisors and employers would like more emphasis on applied Western Blot experience
Drag and drop design:
provides visual impact
creates novel bridge between PC and lab
This circuitry provides a progressive, reflective, experiential learning of the process
Each decision point was transformed into a QuestionMark drag and drop question
Western blot protocol mapped out as a series of questions or decision points.
Does it work and do the students like it?
The simulation was very well received by students and increased confidence with the protocol.
Provides experience of the decision driven process in a safe environment and enhances understanding.
Broadly applicable to any discipline with decision driven processes e.g. Law, Engineering, Business
