When to Reveal the Right Answers

​How the timing of checks for understanding can impact what you learn about student comprehension.

Great teachers want to be sure their students understand content information on a daily basis. They don’t want their students to wrestle with misconceptions, misunderstandings, or mistakes in their thinking that might set them up to struggle as the content unfolds throughout a lesson or unit. As a result, many teachers use small, formative assessments at the beginning, midpoint, or end of a period so students have an opportunity to practice their content and skills, and teachers can assess their understanding at different stages of the learning process. In an effort to ensure that all students have the right answers and a clear understanding of the lesson, many teachers review the correct answers to the assessment before moving on to the next stage of the lesson. 

Example: In a math class, teachers give students the first 5 minutes of the class period to work on three review problems from the day before, to ensure students understand the prerequisite knowledge for the day’s lesson. After the timer rings, the teacher calls on students to share their responses. A few students raise their hands and share what they figured out. The teacher may rewrite what they wrote on the board, and affirm and encourage the students who got the answers correct. When all questions have been reviewed, the teacher moves on to teach the new content, and collects the opening classwork at the end of the period. 

Example: In a Social Studies class, the teacher plays a media clip that shows an animated recreation of an historical event. The teacher is mindful to have comprehension questions that go along with the clip so students can take important notes while they’re watching. When the clip is over, the teacher calls on different students to share their answers to the comprehension questions. After the questions have been reviewed, they collect the responses and move into small group work.

​In both examples, we see the teachers making choices that elevate student collaboration, ensuring students have the opportunity to correct misconceptions, connect with one another, and leverage grouping and discussion strategies to process content information. In both examples, the teacher is using a formative assessment — or a check for understanding — with the goal of assessing student comprehension. And in both examples, the check for understanding may be giving teachers more misinformation, than information.

Check for understanding

​Well-developed instructional design includes multiple checkpoints to assess student comprehension in real time. Highly effective assessment structures may include between 1-3 checks for understanding in a class period, with each check being an opportunity for students to independently demonstrate their understanding and skills related to the lesson objective or learning target. When we jump from the check for understanding task to the review of direct responses, some unintended consequences may emerge. 

One likely scenario is that students who had a misunderstanding or a misconception when working on their own will likely copy down the “right answer” during the discussion. But copying down the answer doesn’t necessarily correct their misconceptions. The unintended consequence is that it appears that all the students have the correct answer, even though some may have simply copied down the answer during the discussion. For teachers using formative assessment data to inform their instructional choices, there’s no evidence that helps them know which students had the correct answer at the time of the assessment, which students had an a-ha moment during the discussion, and which are copying down the correct information but are actually still confused.

Another unintended consequence is that students discover that the right answers get shared immediately, before their work is completed. It’s a lot easier to copy down the right answers later than it is to work through the hard problem in the moment. Some students may begin to opt out of the learning activity altogether and simply wait for the correct answers. This phenomenon may not be noticeable right away — a gradual disengagement happens slowly over time, and can start with students who appear slow to start, or students who are easily distracted. For teachers feeling the pressure of time, it can be tempting to skip to the right answers even if some students aren’t finished. The challenge is that over time, fewer and fewer students finish the task because everyone is waiting for the right answers to be shared.

Creating space for small changes

The good news is that there are a few small changes that can make a big difference. 

Add a reflection. In addition to the discussion of the correct answers, ask students to write a reflection comparing their first response to the correct answer, and share if they made any changes to their thinking or had any a-ha moments in the process. Consider creating a chart on their task that includes space for their individual work, notes from the discussion, and reflection after the discussion. Not only will this provide more insight for you as the teacher, but the students’ metacognition will increase their self-awareness, which supports recall in the future. 

Have students share & give feedback. The standard share out often includes time for students to work independently, followed by the teacher reviewing the correct answers. This practice can be modified to having students post their answers in small groups at the same time, and then visiting other groups' responses and leaving feedback or asking questions. By turning this process over to students, teachers can increase the responsibility and accountability for students to work with their groups and think critically if different groups have different responses. 

Leverage differentiation strategies. Building in differentiation as a result of a check for understanding is an effective way of structuring the lesson. Teachers can plan to use hinge point questions, where students receive a specific task as a result of their answer on a check for understanding question, or Four Corners, where students move around the room in real time to show their thinking and discuss with their peers. Both of these strategies leverage real-time responses and interaction to notice misconceptions and work to address them in the moment.

Checks for understanding are a very valuable touchpoint. Getting in the moment information about what is and isn’t clear for students provides insight into differentiation, student grouping, and tweaks to the next day’s lesson. When we reveal the “right” answer before we can gather information on what students know and can do, we might go for weeks before we realize that students have not been learning what they need to be successful on high-stakes assessments like unit tests, projects, or major exams. 

It’s true: it is important to correct misconceptions, and we don’t want students to sit in frustration if we’re withholding information that can help them learn. And also, when we jump to reviewing the right answers before we’ve had a moment to collect the data or reflect on how students are processing the information in the lesson, we miss valuable insights that help us plan and prepare the learning pathway for students’ success.
