Osborn’s Rules for Brainstorming
1. Criticism is ruled out: Judgment of idea is
suspended until a later screening or evaluation session. Be positive!
Copyright © Texas Education Agency, 2012. All rights reserved.
2. Free-Wheeling is welcomed: The wilder the ideas, the better! Even off-beat,
impractical suggestions may trigger in other members, suggestions which might not otherwise occur to them.
Copyright © Texas Education Agency, 2012. All rights reserved.
3. Quantity is Wanted: The greater the number of
ideas, the greater likelihood of
winners. It is easier to pare
down a long list of ideas than
puff up a short list.
Copyright © Texas Education Agency, 2012. All rights reserved.
4. Combination and Improvement are Sought:
In addition to contributing ideas of their own, students
should suggest how suggestions by others can be
turned into better ideas or how two or more ideas could be combined into a still better idea.

Problem Solving MakingDecisions – GOOD Choices
When making decisions and/or choices, we learn from others. We use their wisdom! We ask others their experience of or on a particular subject. Before we begin this process, we should look at the person (or better, persons).
We should get advice/learn from/someone…….
1. That you admire, or Trust2. Who has been through the Fire
Copyright © Texas Education Agency, 2012. All rights reserved.
3. Who is at the place you want to be
4. Who has made correct choices5. Who has vision (goals)6. Who has a high self-esteem – not pride7. Who is respected by many8. Someone who knows you well

State the problem A problem can't be solved if it isn't understood.
Form a Hypothesis This is a possible solution to the problem formed after gathering information about the problem. The term "research" is properly applied here.
Test the Hypothesis An experiment is performed to determine if the hypothesis solves the problem or not. Experiments are done to gather data. It is very important that good observations and records are made during an experiment.
Copyright © Texas Education Agency, 2012. All rights reserved.
Collect the Data This is where you record your observations, measurements, or information from experiment.
Analyze the Data Just what does all that data indicate about answering the problem you are solving?
Draw Conclusions After examining the data from the experiment, conclusions can be drawn. In its simplest form, the conclusion will be "yes" the hypothesis was.

Steps Example
I want to ride my skateboard down the street

INPUT
I want to ride my skateboard down the streetResources = me, skateboard, and hill

PROCESS
The wheels spin and the board travels down the road
Copyright © Texas Education Agency, 2012. All rights reserved.
OUTPUT
The board moves forward and you ride it (without falling we hope)
Copyright © Texas Education Agency, 2012. All rights reserved.
FEEDBACK
All of the information you receive that causes you to make adjustments. (Example: you see a puddle and shift your weight to steer around it.)

DefinitionsInput: Command given to the system to reach the desired result. Ingredients that go into the system (tools, information, people, time, energy, materials)Process: The action part of the system, the part that takes place to make things happenOutput: The result of the systemFeedback: Information about the output that is used to adjust the systemCopyright © Texas Education Agency, 2012.

Two (2) Types of Systems
Open-loop and closed-loopOpen loop systems have no way of adjusting to changing conditions (closing your eyes riding a skate board)Closed loop systems can change under different conditions (eyes open riding a skate board)
