The verdict is....

Although I'm speaking for the entire team, I would say that we all feel a lot more comfortable with the process now. We also invited the other science teachers who did not participate in the institute. Most of them are very interested in using the program in their classes also.

In addition to user placement quadrat, we also collected data using random placement. This allowed us to experience what most of our students would probably get in their quadrats since they don't have the experience to pick an area they've identified as having invasives , as we did.

What's the verdict?

So do you feel better prepared now that you've done an observation so well on your own? Was it useful to explore where you'll have your students do their investigation?

Love your second piece of evidence.

Yes very useful

We collectively talked about classroom management strategies and brainstormed questions they will have. We also worked through how the data will be entered and how that will work with our students.
