Encouraging Creativity
The brainstorming technique is widely used in industry and academia to encourage participants to generate ideas in an unhindered manner. In an academic context, brainstorming encourages students to participate actively in idea-generation exercises and experience the benefits of a multi-dimensional approach to analyzing problems or solutions. Asking interpretive questions, rather than “yes/no” questions, leads to productive brainstorming.
Scope
The brainstorming technique is applicable to all levels of the engineering curriculum and to all teaching scenarios – labs, lectures or discussion sections. It is especially useful in design courses since it calls for a multiple-answer, multiple-dimension methodology rather than the usual single-answer approach to problems. The brainstorming technique can be implemented in a number of different ways as follows:
The whole class is given a topic to discuss and each student is called upon to contribute an idea. The advantage of this method is that all students participate, and the more vocal students tend not to dominate the discussions. The disadvantage is that the discussions usually do not flow freely as in an unstructured session, and can make some students feel pressured and uncomfortable.
Students are allowed to contribute ideas as and when they think of them. This approach allows for a freer flow of ideas and a more relaxed environment. The drawbacks to this approach are that it can lead to the students not responding at all, or to a few students dominating the discussion.
This is a structured approach. The class is broken into small groups, and each group presents its ideas after an allotted amount of time. The advantage of this method is that the students are likely to be more at ease and willing to express their ideas. The group work also promotes synergy and communication among the students. One obvious drawback to this method is that it more time-intensive than the other two methods.
Guidelines
The following guidelines should be followed with any of the above methods:
- Make sure that everyone agrees on the question or topic of the brainstorm. Write it down on a chalkboard, for example, or give handouts.
- Never criticize students’ ideas or allow students to criticize each other.
- Do not allow students to reject ideas initially. Ideas should not be weeded out until the end of the brainstorming. This keeps the solution path from becoming prematurely narrow.
- Write every idea down. Use a flip chart, blackboard, overheads, Post-It™ notes, or other visual methods.
- Use the words of the speaker when recording; do not interpret.
