Delphi Method of Problem Solving
Practicing solving genetics problems is the heart of the UF course “PCB3063 Genetics.” Dr. Thomas Niehaus and Jennifer Smith designed a series of asynchronous discussion board posts to allow online students to solve problems that would be too difficult for a student to solve alone.
The Rand Corporation originally created the “Delphi Method” for defense research. It was a time-efficient method to gain consensus from a group of experts. (Linstone & Turoff, 2002). Features of this technique include:
- The opportunity for all group members to make a meaningful contribution.
- Asynchronous communication (very helpful for busy online students!)
- Three or more rounds of discussion.
- In order to keep the Genetics students moving through the course material, the Delphi rounds were limited to two in this course.
How to use the Delphi Method
- Explain how it works (adapt the student instructions below).
- Create a problem that is too difficult for a student to solve alone
- Create groups of 5 – 7 students
- Create a separate Canvas discussion forum for each Delphi Round
- Allow threaded replies
- Users must post before seeing replies (important!)
- Graded (if desired)
- Allow liking
- Tip: use a short name such as Wk# DD1 to avoid expanding the gradebook too much
- Assign the discussion to your student groups.
- Create a Canvas Assignment for the final solution submission.
- Assign to everyone
- Allow sufficient time between each of the Delphi discussion rounds and the assignment submissions for students to view the solutions proposed by their peers and re-think their own solution.
- Be sure to provide an opportunity for students to ask questions about the problem.
Example of Student Instructions

- Read the posts from the other members of your group.
- Ask questions about what others have done.
- Respond to questions with your thoughts.
- Use the “like” to tag solutions you think are correct.
Delphi Discussion Round 2
- Armed with the thoughts from your group, take another stab at solving the problem.
- Post your second attempt in the Delphi Discussion – 2 forum (2 points)
- Read the posts from the other members of your group.
- Ask any questions.
- Respond to questions with your thoughts.
- Use the “like” to tag solutions you think are correct.
Final Solution
