This document discusses brainstorming techniques for creative problem solving. It provides background on how brainstorming was developed by an advertising executive in the 1930s who found that group sessions led to more ideas than individual work. The key aspects of brainstorming are outlined as using a relaxed atmosphere to generate lateral thinking and solutions. An activity is described where students are divided into groups, with one leader following correct brainstorming rules of accepting all ideas without criticism, and another leader incorrectly criticizing some ideas. Feedback found the group following rules produced more ideas and enjoyed the process more. Correct tips are listed as accepting all ideas, generating as many as possible without criticism, to improve brainstorming results.
