WHAT IS RESEARCH?
Take a moment and brainstorm the parts of research:
Take a moment and brainstorm the parts of research:
The Scientific Method (TSM)
Everyone has at least heard of The Scientific Method
“The” ???
The Scientific Method
Problems with TSM:
Linear Promotes direct experimentation as the
only method of generating data Presents steps as discrete events that are
completed and never revisited
Alternative:Model-Based Inquiry
Beyond the Scientific Method: Model-Based Inquiry as a New
Paradigm of Preference for School Science Investigations

“MBI” is not:
Arbitrary Random Purely exploratory
“MBI” is:
Based on observations and previous knowledge to…
…form a model that is: Testable Revisable Explanatory Conjectural Generative
Windschitl calls the steps“conversations”
Organizing we know and what do we want to know (informs an initial model)
Creating a hypothesis Gathering data Constructing a scientific argument
One way I use this
Forming aScientific Argument
Describes a potential explanation Uses data collected as evidence Acknowledges any other explanations
that fit the data Describes how you modified your original
explanation
Forming aScientific Argument
The true test of an argument is whether it is backed up by the evidence. This is what I mean when I say your arguments and models must “fit the world”.
Example: One could argue that we do not find road killed mountain lions because they are elusive, but that isn’t how the world works (based on the fact that dead mountain lions show up in the West and Florida)
Example: Black mountain lion reports
1/3 of reports to DEC are of black mountain lions, yet not a single museum sample of one exists
How do we use this data as evidence in our argument?
Example: Black mountain lion reports
There is no need to spend any time arguing that they COULD exist
What if someone’s argument was that they are a different species. Doesn’t that fit?
