8 Word Formula for Success:
Never, never, never, never, never, never,
give up!

A pessimist sees the difficulty in every opportunity;
an optimist sees the opportunity in every difficulty.

Continuous effort - not strength or intelligence - is the key to unlocking our potential.


Science Values #3

Data >> Beliefs & Preconceptions

CVs = Control Everything Else Possible

Results = Observe & Record (Data - Findings - Facts)

Conclusion = Use the Data to Evaluate Your Hypothesis (What You Think It Means)


Science Values #6

Reliability = Peer Review + Scientific Literature Survey / Citation

When in Doubt, Review Procedure & Compare to Others’ Methods & Findings

Great Experiment = Creative Experimental Design + Disciplined Experimental Protocol



Science Values #7: A-C-T-I-V-E Reading

Ask - questions of the text / author

Connect - to prior knowledge (schema)(background)

Track - what’s important (text / image layout)(notes)

I = (Hy)pothesize - build / revise ideas (infer)

Visualize - make labeled illustrations / flow charts

Eureka! -“I Found It!”(synthesize ideas into meaning)



Science Values #8

Zero Tolerance for Deception - Falsification - Omission - Copying w/o Attribution or Citation

Encouraging / Appreciative Comments >> Put-Downs / Complaints

Observable Phenomenon have Natural Causes which can be Investigated by Reproducible Methods


Love & Logic Classroom Values:

I will treat you with respect, so you will know how to treat me.

Feel free to do anything that doesn't cause a problem.

If you cause a problem, I will ask you to solve it.

If you can't solve the problem, or choose not to, I will do something.

What I do will depend on on the special person & special situation.

If you feel something is unfair, whisper to me "I'm not sure that was fair," and we will talk.
