· At the end of the
unit as students are practicing what they have learned is when you can really press
“for evidence-based explanation,” with “constructing and evaluating claims… (and)
drawing final ideas together in models and explanations.”
· The first step is
to develop a claim, doing this with a smaller focus works better earlier on
than having it on the unit topic(s) as a whole
o (CER Claim, Evidence,
and Reasoning).Sets of instructions should have students describe what they are
supporting, what evidence is being used to do so and then how that evidence
fits the claim.
· Once students have
developed a strong CRE they should create a model (connecting the cause and
effect) with a supporting explanation.
This
article was for teachers to better understand the process of using CER in the
class. It started with more of an
explanation on the word claim with if having more meaning in the classroom than
it might in everyday life. After this
evidence is defined with its use in the reason portion explain. I like the article in its use of examples and
providing a template of CER with (1. “Our claim… 2. If this claim is true… 3. Here
is the reason I’d expect this… 4. If our claim was not true… 5. There may be
other explanations….).”
A
theme with this class has been developing students to think like
scientist. Using the CER model seems to
be the popular method to achieve this goal currently. The second article does
well at defining CER as the first describes its regular application to units
with a note on it being embedded throughout the unit. For my questions of use I am again
thinking about the EOC this week. My
students in Biology will be tested on the 26th and we just finished
up our last unit. Going into this next
week I am thinking I would like to create models for the units we have gone
through. Then taking old EOC questions I
would like to see students make a claim for the answer and back it up with
outside evidence they have seen before and give their reason for the answer
choice and possible the reason that the other choices are not correct.
