Analyzing Student Data with Stickers

One of the most important things I’ve learned about being an effective teacher is the importance of using student data in the classroom. Analyzing students’ results on assessments as a whole class tells me if I did an effective job teaching and what I need to work on in the future. When students look at their own results, they each see their areas of strength and areas of challenge. Analyzing data can be very time consuming and this can make it seem like it’s not worth it (especially when teachers have a mountain, or two mountains, of other things to do at any given time). In my own classroom, I’ve tried many different approaches, none of which I was particularly happy with. One day I was looking through my big box of stickers—I can never have enough stickers—and was inspired with an idea to use them to help students visualize their results.   

This method of data analysis all starts with how I organize the tests I use in my classroom. I always organize my tests by subtopics. For example, on a scientific method test I have headings like hypotheses, variables, and qualitative/quantitative observations. All of the questions pertaining to hypotheses will be found under that heading. This way, my students and I are able to quickly look at a section and see how well they understood it.

Take a look at my beginning/end of the year exam. You’ll notice the categories are all clearly laid out on the answer sheet. If you look at the picture of a page from the test, you’ll see the organization of the heading and questions. Having an organized test helps make data analysis much quicker.

After the students take the test and I grade their work, I dedicate about forty-five minutes of class time to analyze results with my students. This seems like a lot of time to look at data, but it gets the students motivated to do better. It shows them their growth and helps them reflect upon their study habits and become better future learners. It also shows the students who didn’t perform well on the test that they still have a good understanding in some areas (which helps prevent feeling like a failure, shutting down, and “not caring”). Also, during that forty-five minutes the students get needed practice with graphing and finding patterns in the results.

What do I do during that forty-five minutes? I start by having the students complete side one of a reflection sheet. (See the picture below.) Side one lists the topics covered in the test and shows each question number in each topic. For example, the Measurement questions on the test were numbers 11-20, so all of those numbers are listed under the Measurement heading.

Side one of the reflection sheet has students circle the question numbers they get correct and find the total number of questions correct for each topic. Then they calculate their percent correct on each topic. My students always need reminders of how to calculate percent, and I usually let them use the calculator on their phones for this.

Once side one of the reflection is completed, it’s time to determine best topics and most challenging topics. Side two of the reflection sheet helps with this. Side two has students consider their best and most challenging topics and try to determine the reasoning behind their success or misunderstanding.

Before class, I set up a poster or a group of papers with the test topics listed out. I sometimes divide each paper by class period or have separate posters for each class. Other times, I have all of the classes put their stickers on the same poster. 

Now it’s sticker time! I give all of the students two different colored stickers. You’ll need a lot of stickers for this so I buy some basic dot stickers to save money. This pack of 315 stickers costs about a dollar. I need two packs for my 200 students because I use only the blue and the red. Foil stars work well for this, too.

The blue stickers represent each individual student’s best topic. The red stickers represent his or her most challenging topic. Inevitably, I have students who have multiple best or worst topics. For those students, I tell them to select the topic that came easiest for them (for the blue sticker) or the topic that just never made sense to them (for the red sticker). The students who excelled on the test are still given a blue and a red sticker. The only exception I make to a student using both stickers is if the student feels very strongly that he or she had no challenging topic; then that student can just use a blue sticker on a favorite topic. Alternatively, you can have an additional topic on your poster that says “All” for students who aced the test. Students aren’t allowed to choose “All” for their red sticker because it feels too negative; there is always a topic that’s better than others.

After all of the stickers have been placed on the posters, we can quickly determine which topic is better than the others and which topic looks bloody. You can easily see on the posters below that the best topics are the Scientific Method and the Human Body. At a glance, you can tell the most challenging topics are measurement and either Genetics or Physical Science. 

We tally up the number of blue stickers and the number of red stickers for each topic. Then the students make a bar graph of the class’s results. We have a thorough discussion of possible reasons for the strengths of certain topics. (Potential reasons for success could be more time spent on that topic, a project or experiment that helped with understanding, or the level of interest students had.) We also discuss the likely reasons for the red topic. (Possible reasons could be difficult subject matter, more math involved, or many students being absent during that topic for weather or sports reasons.)

I like this method of data analysis because it is more student-centered. It’s not very time consuming for me. I don’t have to do much to analyze the data other than organize my tests a certain way and make some quick posters. Showing the results of tests using stickers makes it very easy for students to see their results and the results of the class. It gives them and me instant feedback that we can use to increase the understanding of content.

If you  have any questions about how to use this in your class, please comment below or send me a message using the Contact Me tab of my blog. My seventh grade science exam includes the reflection sheets seen on this blog and can be purchased at my Teachers Pay Teachers store.

Back to School SALE!

Hello everyone!

Teachers Pay Teachers is having a site-wide sale on Monday August 3rd and Tuesday August 4th. Everything in my store will be 20% off during these two days. If you use the promo-code "BTS15" at checkout you'll save even more money.

 BTS Sale

In my store you'll find many useful resources for the first week of school. I always give both a student survey and a parent/guardian survey in English and Spanish in the first couple of days of school. Another resource I use in the first week is the seventh grade science diagnostic exam so I get a good idea what my students already know and what they need to learn.

In the second week of school we start learning all about lab safety. This lab safety package can help you get your students ready for all of the fun experiments they'll do this year.

Make sure you check out the sale happening this Monday and Tuesday!
