RULESRespect each other and the teacher. Please be quiet and raise your hand. We will call on you to answer.

Never laugh when another student is being corrected for behavior.


What will we be doing?

Day 1 = Intro Notes: (Daily)– Grades, Percentages, TAALLS, and Good versus

Bad Decision Making into the document provided

Day 2 = DR. GABIC and Scientific Problem Solving Methods, and the Universal System Model (Major)– You will solve the three (3) puzzles and put the

answers into the document provided.


What will we be doing?Day 3-4 = Solve the Problem: (Major)– Given ONLY the materials provided, you will

solve the problem.

Day 5 = Test the solution day

Day 6 = TAKS Math and Review for Test (Major)– Complete the TAKS Math-based problems given

and take the practice test

Day 7 = DR. GABIC Problem Solving Test

class, should other students laugh about it?

TAALLS: Manners and how to get

alongThe TOP 6 items your future employer wants you to know and do. These will help you get and keep your job!


TAALLS:#1 -T. Make it to work

every day on Time (early).


TAALLS#2&3- AA. Come to school/work dressed

Appropriately with

a good Attitude!Copyright Texas Education Agency (TEA)

TAALLS#4- L. Do not make vulgar, abusive, or obnoxious

Loud noises.


TAALLS#5&6- LS. Do not Lie

or Steal and do not

tolerate those who do!


Osborn’s Rules for Brainstorming

1. Criticism is ruled out: Judgment of idea is

suspended until a later screening or evaluation session. Be positive!


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.


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.


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


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


Meet DR. GABIC.


DR. GABIC

D- Define the problem clearly

R. G- determine Results and Goals

A- come up with 3 Alternative solutions


DR. GABIC

B- choose Best solution

I- Implement the solution

C- Compare and Change if needed


DR. GABIC

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.


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.


The Universal System Model


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


OUTPUT

The board moves forward and you ride it (without falling we hope)


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 (TEA)

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)
