When I first began to shift my curriculum to support the Next Generation Science Standards, I was a bit overwhelmed! And frankly, I am still overwhelmed on some days when I work with my students to support their productive struggle and allow them to “figure things out!” I used to hear requests from my students like “It would be so much easier if you would just tell us the answers!” or “Would you please just lecture to us?” They quickly learned that the answer to both of those requests was “You will gain so much more if you work to figure it out!” We (my students and me) all know now that the shift to incorporate the science practices as identified by the NGSS into our classroom has transformed our teaching and learning space.
One of the practices I initially struggled to include was arguing from evidence. What exactly does that mean? How do you get students to productively argue their findings? How do I ensure that all students are learning and sharing their ideas?
In my opinion, the practice of arguing from evidence simply means that students must use evidence (data) found in their experiments, a video, an article, or another learning activity to support a scientific claim through reasoning. In my classroom, students develop the Claim, Evidence, Reasoning (CER) framework after much discussion with a partner, then a group, then a whole class.
I never really felt successful leading a classroom discussion using evidence until I was introduced to the process of “productive talk” to support the learning and ideas developed by students. Productive talk uses leading questions to allow students to show what they understand about a concept. After I was introduced to the idea of Productive Science Talk through the Talk Activities Flow Chart and Talk Moves while participating in an IMSP I-STEM initiative created to fully investigate and support the shift to the NGSS in Illinois, I became much more confident. This program was funded by a Math and Science Partnership (MSP) grant in Illinois from July 2015-July 2017. Our facilitator, Nicole Vick, introduced us to these tools, and they provided the support I needed to determine which talking strategy to use in class activities. I determine my end goal and purpose within the lesson, and I match the activity to the strategy that will best support the learning objective. I try to use multiple strategies to support the students’ discussions and learning styles.
When students start talking, they start learning! I have seen a dramatic increase in learning and retention now that I have incorporated productive science talk and talk moves into our learning activities.
In the beginning of the year, I must scaffold the learning activities so that the data to support the claim are easy to identify. I routinely remind my students that their claim must be supported by sufficient and applicable evidence as they work to figure out the lesson.
We work hard in the beginning of the year to develop this skill in small groups. My go-to talk move to encourage students to find the appropriate information and share is “Time to think” followed by “Partner talk.” I use this to allow students to first develop their ideas solo, then with one other person, then discuss them with their group of four. I tell the students to talk with one of “their people.”
The next steps in the discussion are organic. You will “feel” the right time to move on to table discussions, and finally, a class discussion. Developing this practice as a team is essential to ensure students are confident going forward. As I move around the classroom, I hear students asking one another which pieces of data would best support their ideas. If it seems that a student is on the cusp of the right idea, I will ask them to explain themselves, and I will use another talk move, “Say more,” in which I ask them to expand on their idea. Often when prompted, the students will figure out the right information.
We routinely use a claim, evidence, reasoning pattern to ensure students have their ideas ready to present before a class discussion ensues. After students have reached consensus within their table groups, we hold classroom discussions. Students are more motivated to share their ideas if they are confident in their responses.
When I first tried this, I was most worried about buy-in and participation from my reluctant learners. I also worried about meeting the needs of my special-needs students while challenging the highest-achieving members of the classroom! I wondered how in the world could arguing from evidence support all learners.
To ensure participation by and support for everyone, we establish classroom norms during the first week of school. I have students participate in two or three learning activities before we take a break from biological concepts and figure out how to best learn in this way. To have a productive discussion before developing group norms, I have each student independently identify 1) what they did to support the group, 2) what someone else did to support the group, and 3) what they could have done better while in the group. Each table group of four students then shares their ideas and develops “group norms.”
I then lead a discussion to establish a set of class group norms. When doing this, we find that everyone wants equal say and everyone also wants the whole class to contribute! Some groups also identify the need to stay on task and respect the ideas of everyone. I have found that my special education students are able to contribute to the smaller groups with more confidence after they hear that their peers trust them—and need them—to share their ideas. Once they share in a small group, it becomes easier to share with a classroom full of peers!
Encouraging all students to identify the pieces of data that then support their claim from a learning activity has actually increased the engagement of students of all levels in my classroom! It is exciting to hear my upper-level students interact with the students who struggle. They work together, they begin to ask each other questions, and they are able to develop appropriate and accurate conclusions when they verbalize the claim. Hosting class discussions to encourage students to “take a stand” has made my classroom more engaging. When students learn to support their claim with evidence and share their ideas, I hope they eventually use this skill in other areas of their lives for the rest of their lives!
If you have any suggestions for other activities we can use to encourage class discussions so students can learn to argue with evidence, I would love to hear them!
