The post BigBlueButton World 2025 Recap appeared first on BigBlueButton - Open Source Web Conferencing.

The BigBlueButton team – represented by Blindside Networks, iMDT, and Mconf – participated in Paris HackDays, an open invitation by Direction Interministérielle du Numérique (DINUM), the Interministerial Directorate for Digital Affairs within the French government.

Today, DINUM offers La Suite, an integrated suite of open source tools that help governments be more efficient and work towards achieving digital sovereignty. One of these tools is docs, a Notion-like clone that recently reached number one on Hacker News.

The HackDays was an invitation for open source projects to come together and improve these tools for the French Government, and by extension, all European countries.

BigBlueButton has a special place within the French Government as the official State Webinar system.  

We of course attended!

The Problem

For every webinar meeting within the French Government, the problem is capturing, summarizing, and re-using this content from the session.

Common questions include

• Where can I find the attendance list and voting results?
• What were the key outcomes?
• What are the next steps?

As meetings are recorded, the organizer could manually extract the audio, run it through speech-to-text, and use the text with AI to summarize the meeting minutes into a shared document (or email out) for further collaboration, perhaps to better prepare for the next meeting.

We thought we could do better.

The Solution

Our idea was to embed docs into BigBlueButton and use AI to summarize the meetings.  

First, we broke the problem down into four steps

1. We extended the BigBlueButton API so it would also create a new docs document for each meetingID. Since docs doesn’t provide such an API, we used playwright to login to docs, create a new document, and return the URL. That was definitely a hack, but it worked!
2. We embedded docs both in a panel and main area in BigBlueButton 3.0 (more on that below).
3. We created a new recording format called transcript that both called Albert, DINUM’s internal AI to do speech-to-text and create a summary of the meeting (key points and action items).
4. We appended this to the corresponding docs document

Here’s the result in a 1:30 minute video we did for the final pitch on Day 3.

We placed in the top 10!

From a field of 300 developers, there were 53 projects submitted for judging in the competition.  

We made the cutoff for the top 10 and presented on Day 3 to the jury of representatives from Germany, France, and the Netherlands. 

While we ultimately didn’t place in the top 3, everyone was impressed with our accomplishments.

“The quality of submissions for the first annual Paris HackDays was amazing. The French Government has been building out a suite of open source applications, called La Suite, to make collaboration more efficient and strengthen digital sovereignty. Today, we use BigBlueButton as our state webinar system and recently created La Suite Docs, a notion-like product for simple, secure, and effective note taking and collaboration,” says Samuel Paccoud, Chef de Pôle Suite Numérique.

“At Paris HackDays, the BigBlueButton team demonstrated a seamless integration of Docs into BigBlueButton, as well as an AI generated summary of the meeting automatically uploaded to Docs, for increasing the efficiency of collaboration of every webinar within the government.”

Embedding docs into BigBlueButton

How were we able to achieve this integration in two days?  (Actually, the days were from 9:00 am to 11:30 PM, so it felt more like four days :-).

It was possible because of BigBlueButton 3.0 and its new plug-in architecture. We created a plugin that embedded docs, via an iFrame, into either the left panel or the main presentation area.

This project enabled us to showcase the ability for BigBlueButton 3.0 to move from an application to a platform.

Like Moodle, developers can extend BigBlueButton 3.0 with their own plugins.  This brings modularity to BigBlueButton where it can be extended and enhanced without modifying the core product.

This also accelerates innovation as both plugins and the core can develop in parallel.

Creating the AI Summary

BigBlueButton already has a modular recording processing system that supports the creation of multiple recording formats.

For the Paris HackDays, we created a new recording format called transcript.

When transcript processes the captured data from the webinar, it calls Albert, DINUM’s internal LLM, twice.  The first time to do a speech-to-text of the meeting.  The second time to summarize that text into key points and action items from the meeting.

As a new recording format, it would also automatically appear to users within B3Desk, the open source front-end that DINUM provides to all government employees.

Here is a mockup of how the Docs link would appear in B3Desk, ready for the organizer to access the AI generated summary for further collaboration and subsequent meetings.

For more information

The purpose of our attending Paris HackDays was to support how the open source community can help Europe accelerate towards digital sovereignty.

We believe the integration with docs would make the French government more efficient as well (they held over 151k sessions in the last 12 months).

Today, BigBlueButton has 

• 150+  developers who have contributed 5 or more merged pull requests, and
• are localized into over 65 languages, and 
• Major learning management systems, including Moodle, Instructure (Canvas), PowerSchool (Schoology), and Jenzabar (eLearning) have embedded it into their core products. Together, these integrations cover more than 75% of the world’s learning management systems for K-12 and higher education.

The project recently completed two BigBlueButton Developer Summits, Dev20 in Berlin, Germany (Dec 2024) and Dev21 in Porto Alegre, Brazil (April, 2025), bringing together the global BigBlueButton community to accelerate development.

Below are the four key themes from the past two developer summits that give insight into our path towards building the world’s most effective virtual classroom.

1. Transformation from Product to Platform

“The addition of plugins moves BigBlueButton from a product to a platform, and when you think of a platform, you want a solid foundation that is modular and extensible.”
– Fred Dixon, Keynote for Dev20

A central and foundational theme is the significant shift of the BigBlueButton project from primarily a virtual classroom product to a more versatile and extensible platform.

The latest version of BigBlueButton 3.0, released on February 28, 2025, now includes a plugin architecture designed to lower the barriers for developers, companies, and the global community to extend BigBlueButton’s functionality without modifying the core (see new plugin SDK).

For example, BigBlueButton 2.7 had built-in transcription based on the live captions.  In 3.0, this is now a plugin that enables the project to quickly and easily provide the expected functionality (such as downloads) of a live transcription.

2. Significant Under-the-Hood Overhaul for Performance and Scalability

“You can see the number of users increasing to 700” – Daniel Schrieber, Stress Testing BigBlueButton

We made some big investments in the core of BigBlueButton. The first was rewriting the client-server integration and replacing older components (MongoDB and Meteor) with Hasura and Postgress (using GraphQL) for improved scalability. The second was improving the audio and video quality, especially for lower bandwidth connections, by moving away from FreeSWITCH and MediaSoup towards LiveKit.

3. Redesign of the User Experience (UI/UX)

“A lot of the updates that we’ve done so far have been through the findings that we received from the user experience studies” – Júlia Rathke and Tyler Copeland, New UI Improvements and Refinements

A multi-year effort continues to completely redesign the BigBlueButton interface, informed by extensive research and user testing. This aims for a more modern, intuitive, and consistent user experience. The results of this will be visible in BigBlueButton 3.1, which had its first beta in April 2025.

You may see us make a big splash about the upcoming release of 3.1 later this year with the tagline “Welcome to the post-Covid19 BigBlueButton.”

4. Deep Commitment to Active Learning and Pedagogical Tools

“So now if the teacher wants to make any corrections, they can just put a check mark [next to the student’s whiteboard] and it becomes a two-way collaboration between the teacher and that student.” – Kert Browne, Whiteboard Vision

The project remains fundamentally focused on promoting active learning and feedback to increase learning outcomes, distinguishing it from passive video conferencing tools (passive learning has very poor learning outcomes compared to active learning).

BigBlueButton offers built-in tools for active learning (like whiteboards, polling, breakout rooms) and live analytics (via the Learning Analytics Dashboard) to ensure every student learns.

One project within BigBlueButton we continue to advance towards is “Whiteboard Vision,” the ability for the educator to give each learner their own whiteboard, along with a birds-eye view to see who may be struggling and give them feedback when it matters most: in the moment.

Welcome to Part 2 of our specialized blog series, geared to address teachers’ concerns about monitoring student engagement when students aren’t using their webcams. In Part 1 of this series, we pointed out a common worry from teachers: if students don’t use their webcams it is hard to tell how much they engage with the material and if they are learning. We also offered insights on harnessing your longstanding in-class experience to augment student participation in the digital environment.

In this follow-up post, we introduce you to six exceptional BigBlueButton tools. These tools aim to maximize the deep learning potential of virtual classrooms, ensuring your students remain actively engaged throughout the class. Stay tuned!

The post Boosting Student Engagement in Online Teaching: The Webcam Dilemma – Part 2 appeared first on BigBlueButton - Open Source Web Conferencing.

Teaching to ‘black boxes’ often feels like you’re not teaching to anyone. Some teachers even wonder if it’s an act of defiance from the students or if the students have ghosted the lesson altogether. What has been learned, in this new era of online teaching, is that student engagement is not based on whether or not they turn on their cameras. There are a variety of reasons students might avoid presenting a digital close up of their faces. 

Regardless of whether students turn on their screens, a teacher’s job is still the same: to share knowledge, provide guidance, and encourage student engagement. Encouraging student engagement might seem like the most challenging task. Just like how helpful it is for students to have informative feedback, it is also helpful for teachers to receive feedback from students to know how and when they are engaging with the material.

This feedback doesn’t have to come from their webcams. There are many skills that teachers already possess, especially if they have experience teaching in-person. But these skills may not have been adapted to the virtual classroom because staring at your own face while teaching is distracting, right? We all need reminders to recall those foundations, especially when teaching online is a new approach. How, specifically, can we encourage student engagement using in-person skills that we might already know?

Transferring In-Person Teaching Skills to Online

Here are a few strategies to increase student engagement online:

• Offer students an orientation: Make sure students are comfortable with and know the tools of the platform so that they know how to participate. Before your first class, share this Student overview to get them started with the BigBlueButton online classroom. 
• Connect with students before class: Prior to class start time, when students walk into a physical classroom, we greet them. In a virtual classroom, we can do the same. The great thing about a virtual classroom is that, in a sense, they will be wearing a nametag each time they enter. We will never get the chance to forget anyone’s name!
• Encourage questions during and after the lesson: Remind students at the beginning of class to ask questions or share comments during class via the Hand Raise button with a direct message to you or a group message to the class. They can also use the Emoji features to share reactions. Not every student is comfortable raising their hand in front of classmates, so the online platform offers less conspicuous ways of engaging. Teachers can use the Lock Feature if needing uninterrupted lesson time.
• Ask students questions and allow some awkward silence: Pause your lesson and ask students questions throughout the lesson. After asking questions, allow for a pause (which is only awkward if you make it that way). Yes, asking students questions is part of Teaching 101, but when you can’t see how students are processing your questions, teachers can jump in too quickly with the answers themselves.

• Set homework and give time to complete in-class: Just as in physical classrooms, students might have to work outside of the lesson, alone or in groups. Tasks set and completed ‘at home’ can be assessed as usual through work submitted, feedback, or demonstrations in the classroom. Teachers can give time to start or complete the homework in class.
• Provide incentives: Give rewards for participation, such as leaving time at the end of completed work to do a fun activity or socialize. You could also set up a friendly competition, either within groups or classroom-wide. 

You can see that none of these strategies require students to turn on their cameras. While you still might prefer to see the students you teach, there are many ways to get to know your students and motivate them with these strategies. BigBlueButton is designed for the ease and success of online teaching. Stay tuned for Part 2 of this post to help you increase student engagement online using tools offered in the BigBlueButton platform.
