Though you may have already guessed from the name itself, applying the CER framework to an explanation or argument goes something like this1. This is similar to an attorney who is trying to convict a criminal.
Includes one or more scientific principles that are important to the claim and evidence. Thus, I have started using C-E-R to help guide them through the process of making sense of their data. What does the lawyer have to do with the evidence to make her point? Provides the justification for why this evidence is important to this claim.
You can find CER grading rubrics on the internet but it is not difficult to create your own once you understand what each piece of the framework looks like when done properly. To the girl, her argument sounds completely valid.
Just cer science writing activities an attorney needs to collect evidence and express to the judge how it connects to their claim s that the defendant committed the crime, scientists must do the same thing. Sufficient—Use enough evidence to support the claim.
Students generally respond with the following statements paraphrased: During my 1st year of implementation, I only used CER in the lab setting.
The ultimate goal is to get my students to explain how the egg got into the flask, but I must first show them how to make sense of their data before they can tackle that rather daunting task.
Examine each piece of evidence mentioned and determine if it supports the claim or not. It really is a classroom cultural shift with respect to how students interact with their thinking and, because of that, it takes time.
I regret that decision because the nature of our content provides opportunities for students to practice and reflect on their scientific explanations pretty much daily.
Feel free to share any experiences you have had with CER or anything related to evidence-based explanations.
I can honestly say that consistently and effectively implementing this was and still is a process that simply takes time. Ties together the claim and the evidence Shows how or why the data count as evidence to support the claim. I encourage you to download their CER poster for your classroom.
In class, we are going to learn about Claim-Evidence-Reasoning as a structure to help us to correctly explain how we know what we know. Upon examining the evidence, students have an opportunity to critically think about why each piece of evidence justifies her claim.
I begin by asking a fairly basic question, "Does air have mass? They staple the sheet into their science notebooks. Example C - Determining the mathematical relationship between molarity, moles of solvent, and volume of solution: The Basics of Claim-Evidence-Reasoning The image below does a good job of highlighting the various parts of Claim-Evidence-Reasoning C-E-Rand the concrete nature of these guiding questions gives my students a solid structure to present their explanations of scientific phenomena.
C-E-R also promotes facilitating discussions, seeing the big picture, questioning alternative conceptions, encouraging collaboration, and, most importantly, shifts the focus to student conceptual understanding by using evidence to support their ideas Reference: One source of error that affected our percent yield was our filter not being closed enough when in the funnel.
Practice Engaging in argument from evidence. I must explain how the evidence supports my claim. That is an area I have wanted to see improvement in since I began teaching!
In this class, we will always clearly explain our understanding using C-E-R. Doing so has allowed us to share, compare, and reflect on student work in ways that we rarely would have ever done in the past.
The most efficient and accurate method I can suggest is to create a uniform rubric that will be used for every CER explanation. Qualitative, Quantitative, or a combination of both.Writing in science using the CER method helps students understand material better and learn how to support their ideas with evidence.
This type of writing is helps students meet NGSS standards which require students to engage in argument from evidence. A CER (Claim, Evidence, Reasoning) is a format.
for writing about science.
It allows you to make claims and conclusions about your data in an organized, thorough manner. See the subpages for a sample and the grading. rubric.
Subpages (2): CER Rubric CER Rubric and Sample. Common Core Standards: Writing in History, Science, Technical Subjects WHST.6‐ Write arguments focused on discipline‐specific content. • Introduce claim(s) about a topic or issue, acknowledge and.
The CER format to writing explanations is not a trivial thing for your students. You will need to explicitly introduce and model it for them. They will need support throughout the year as they get better at writing explanations.
1 Middle School Students and Science Writing: Supporting Claims with Evidence and Reasoning Katherine L. McNeill Boston College Overview of Session Critique examples of student writing Discuss importance of scientific explanations and argumentation.
Argumentation is central to productive science learning. The following Many step-by-step lab activities can be modified to allow students to create their own procedures and discuss them before deciding on a shared class procedure.
Students can create different Scaffolding Writing & Talking.Download
