Teaching Interactively Online with Scribble Together

Teachers Know: keeping students engaged and interacting remotely is immensely challenging. It’s more work, not less, than teaching in person.

Teachers also know: students learn best when they interact with the material and with each other in class, actively. Trying to do this effectively online brings many more challenges.

We’ve been thrilled to hear from teachers that Scribble Together has helped them implement virtual versions of interactive classroom activities, and even made new forms of interaction possible. They especially appreciate the simplicity of the app.

In this article, we’ll describe one such example from Professor Federico Ardila’s classroom in detail. For more examples, you can also check out this teacher Zach Schroeder’s description of how he’s using Scribble Together to teach grades 9–12 Precalculus, Calculus, and Intro to Engineering (co-taught with Geometry, also using Scribble Together).

Summary: After a short lecture, Federico gives students a question and puts them in Zoom “breakout rooms.” They work with their groups while writing in designated separate areas of the Scribble whiteboard. When the whole class regroups, everyone “walks” through student work together, similarly to how they might have done a gallery walk around the whiteboards in a physical classroom. Federico closes with a second short lecture, where he uses students’ work to motivate the main points of the class.


During the fall of 2020, Federico Ardila taught Abstract Algebra to a mixed class of undergraduate and graduate students (about 50/50) remotely. SFSU is a public university located in California, in the United States. The attendees are mostly in California.

Setting up(1-2 min)

Before class starts, Federico creates a Scribble Together whiteboard on his account on the iPad and opens the browser on his laptop to the same whiteboard. (He sends himself the Scribble link via iMessage.)

He shares the browser to the students via screen sharing on Zoom. That way everyone is looking at the whiteboard alongside people in the class and the zoom chat together. He also shares the Scribble link in the Zoom chat, which students will use to collaborate later during class. As new students arrive, Federico or other students share the link with them on the chat.

Federico names the whiteboard with the name of the class and lecture number. Later he can search for “Algebra” on the All Boards screen to see only the boards from his class.

Starting the class - mini lecture (about 35 min)

Federico often opens the class by speaking for a little while, using Scribble Together the way he would have used a whiteboard in a classroom (15–20 min).

Group Learning
Sometimes, students benefit from seeing patterns that emerge if they all hop in and tackle an exercise at once, each bringing in their own strategy and perspective. This shows student work from one such exercise.

Breaking into groups - active learning(about 20 min)

After the short lecture, Federico writes down a question on the whiteboard for the students to think about, play with, discuss, and hopefully discover something. He tells them he’s going to put them in groups of three or four students and that they’ll have about 10–15 minutes to discuss the question. This usually winds up being seven or eight groups, created using Zoom’s breakout group feature. There are designated roles:

Sometimes Federico will assign roles such as “whoever’s name starts earliest in the alphabet will be the scribe.” Other times he lets students choose their roles.

While groups start their discussions, Federico quickly scrolls down the whiteboard using two fingers to scroll, and designates an area for each group by writing “Group #” and drawing a horizontal line. This takes just a few seconds, and just around the time he’s done, he sees the students’ handwriting start appearing.

Organizing groups
While groups start their discussions, Federico quickly scrolls down the whiteboard using two fingers to scroll, and designates an area for each group by writing “Group #” and drawing a horizontal line. This takes just a few seconds.

While students begin writing in their groups, Federico can take a moment to breathe (online teaching is tiring!!!), stretch, and get water. He then scrolls around the whiteboard to check out what students are writing. If there are misunderstandings or really interesting thoughts happening, he can tell just by seeing the writing, the same way he would if he were walking around the physical classroom. If a group looks like they might need an intervention, he can hop into their break out room for a few seconds to say something and then leave.

Bringing the class back together - sharing back, and closing mini-lecture(20 min)

Federico will use Zoom’s functionality to give students a one-minute warning, and let them know to wrap up and write down final observations — either on the Scribble board or on the Zoom chat.

He’ll then give students a couple of minutes to scroll around the Scribble canvas and the Zoom chat to see what their classmates wrote during the break out groups. He’s looking alongside the students as this happens. It never feels like quite enough time, but it’s really great for students to see each other’s thinking, and for their work to be seen by each other immediately.

Then Federico takes back control of the scrolling and writing, and walks through the group work with the whole class. For example, he might ask Group 3 to walk the class through their observations or thinking. He’ll talk about what he notices. He tries to speak with the less-talkative groups — especially at the start of the semester and if he can see they have great things to add to the class — and offers encouragement to them, so that they’ll see that their contributions are valuable and valued.

After class is over, Federico will turn off the ability for guests to edit to keep the board preserved as it was at the end of class.

A note on teaching during challenging times

Federico has spent years cultivating a practice of humanizing the classroom. You can read more about this in his paper Todxs cuentan: building community and welcoming humanity from the first day of class. He finds this work much harder to do virtually, and he has found Scribble Together to be a very useful tool for humanizing online teaching.

At the start of the semester, Federico used the shared canvas and a community agreement to set the tone for the students’ co-responsibility in their own and each other’s learning experiences. He imported the PDF of the community agreement into Scribble Together for the class to co-read, and students underlined areas that were particularly meaningful to them as they were reading. Areas that were meaningful to a lot of people visually stood out, and Federico asked students to share why they underlined particular words. The idea was that, after beginning with a very easy and anonymous way of participating using the whiteboard ink, more students might be more ready to speak.

Underlining as we Go
The class reads the community agreement together in Scribble Together on the first day of class, underlining parts that mean something to them as they go. They then gather in break out groups and discuss.

The intentional work to set up the atmosphere of the class also laid the groundwork for both group work and getting through difficult moments.

On days when students were having a particularly hard time due to factors outside the classroom, Federico asked the students questions such as “How are you feeling being here today?” and gave them a moment to respond in the open whiteboard. Many students drew instead of writing.

If you’re currently tasked with teaching remotely, we hope this article helps you in some way. We’re a small indie team, and purchasing Scribble Together membership helps support our development efforts and keep the project sustainable. We also know these are really challenging times. If you are an educator or student and want to try Scribble Together for a little extra time, you can download it for iOS here or start using it on the web here, hit “Join Board” on the All Boards screen, and enter the code “🧼🧼🧼🧼” for four months of membership we’re offering as mutual support. In return, we’d love to hear from you.

Special thanks to the San Francisco State University students who gave us permission to include their student work in this article, and also, nice work y’all! Everyone else: remember to recruit and hire from state schools!
