Time for Questions
If you don’t get a word in edgewise.
Type your question into the question
box.
Preconceptions :Three – Two - One
• Three Inquiry Standards that will be answered as a two point questions
• Two Inquiry standards that will be only Multiple Choice
• One inquiry standard that will not be tested
Inquiry?
• Ask Questions• Plan Investigations• Collect Data• Repeat for reliability• Understand Models• Emphasize Evidence• Communicate results• Be honest
2 point possibilities• Plan an investigation
• Understand models• Evidence for Conclusion• Evidence for

Pause Part 2
In Conclusion(1)Conclusive statement
(2)Supporting data: reported data are the lowest and highest conditions
(1)Explanatory language, connect or compare the supporting data to the conclusive statement

Explanatory Language
How well do students write conclusions?
High data
Low data
scored 2 points
What can you conclude about writing conclusions?
Conclusive statement 42%
Explanatory Language 22.6%
0.6 out of 2 is the mean score
Students score 20% lower on explanatory language
Conclusive statements are credited 42%Explanatory language is credited only 22.6%
Teachers should help students understand “explanatory” language” which is the lowest scoring attribute in writing conclusions at 22.6%.

Models
Model Guide
Example
• What real object is this a model showing?
• What is accurate about the model
• What is inaccurate about the model?
Models in your science kits
• Carts
• Stream Table
• Day & Night • Moon Craters
9-12 Reliability & Validity
Reliability: An attribute of any investigation that promotes consistency of results during repeated trials.
Validity: An attribute of an investigation that describes the degree of confidence that data collected and logical inferences are accurate representations of the phenomena being investigated.
