Open Source Software DevelopmentActivities & Teaching Strategies
Active learning works because open source development relies on hands-on collaboration, peer review, and real-world artifacts. Students need to experience decentralized coordination firsthand to grasp how thousands of contributors build and maintain software without central control. By engaging with authentic projects and debates, students move beyond abstract definitions to understand the practical implications of open development.
Learning Objectives
- 1Explain the role of version control systems in facilitating collaborative open source software development.
- 2Analyze the benefits and drawbacks of contributing code to public open source projects.
- 3Compare and contrast the core principles, licensing, and governance models of open source and proprietary software development.
- 4Identify key components of an open source project's community and contribution workflow.

Gallery Walk: Open Source Projects Students Already Use
Post six stations with descriptions of open source projects embedded in everyday tools (Linux, Firefox, Python, VS Code, Wikipedia, OpenStreetMap). Students rotate and add one observation: who maintains this? How do they coordinate contributions? What would happen if the project disappeared? Class synthesizes observations into patterns.
Prepare & details
Explain how open source software development relies on version control tools.
Facilitation Tip: For the Gallery Walk, display printouts of project interfaces and license summaries around the room so students can physically move and examine artifacts.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Case Study Analysis: Contributing to an Open Source Project
Groups review a simplified GitHub contribution workflow -- finding an issue, forking the repo, making a change, submitting a pull request, addressing review comments. Each group identifies the most likely point of friction for a first-time contributor and proposes one way the project could lower that barrier.
Prepare & details
Analyze the benefits and challenges of contributing to open source projects.
Facilitation Tip: During the Case Study Analysis, assign each student a role (e.g., maintainer, contributor, user) to focus their reading and discussion on specific stakeholder perspectives.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Comparison Chart: Open Source vs. Proprietary
Partners create a two-column comparison of open source and proprietary software development along five dimensions: funding model, quality assurance, feature prioritization, user trust, and contributor motivation. Pairs share their charts and class discusses where the two models have genuinely different strengths.
Prepare & details
Compare the development models of open source and proprietary software.
Facilitation Tip: Use the Comparison Chart to require students to cite specific examples from the projects they analyzed in the Gallery Walk, linking evidence to their comparisons.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Think-Pair-Share: Should Tax-Funded Software Be Open Source?
Present the argument that software built with public funding should be released as open source. Partners discuss: what are the strongest arguments for and against? Each pair shares one argument they find most compelling and one they find least compelling. Teacher facilitates a class synthesis of the key considerations.
Prepare & details
Explain how open source software development relies on version control tools.
Facilitation Tip: In the Think-Pair-Share, provide a structured sentence frame for the 'share' phase to ensure equity in participation, such as 'I think [position] because [reason], but my partner’s point about [counterpoint] made me consider...'.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
Experienced teachers approach this topic by framing open source as a social system first, not just a technical one. Avoid starting with definitions of licenses or version control commands, as these can overwhelm students. Instead, begin with recognizable tools (like the browser they use) to build relevance, then layer in technical concepts as students encounter them. Research shows that students grasp decentralized collaboration best when they first experience the problem it solves, so start with a scenario where code conflicts arise naturally before introducing Git.
What to Expect
Successful learning is visible when students can explain how version control enables global collaboration, compare licensing models, and recognize the diverse ways people contribute to open source. They should move from saying 'open source is free' to articulating how community review, licensing terms, and contribution pathways function in practice.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Gallery Walk: Open Source Projects Students Already Use, watch for students assuming that free software equals lower quality because they conflate price with value.
What to Teach Instead
Use the Gallery Walk artifacts to point students to evidence of industry adoption (e.g., Apache server powering 50% of websites) and discuss how community review and transparency maintain quality.
Common MisconceptionDuring the Case Study Analysis: Contributing to an Open Source Project, watch for students believing that 'open source means anyone can use the code for any purpose' without considering licensing terms.
What to Teach Instead
Have students examine the actual license file in the project repository and summarize its key restrictions or permissions in their case study notes.
Common MisconceptionDuring the Comparison Chart: Open Source vs. Proprietary, watch for students assuming that only expert developers can contribute to open source projects.
What to Teach Instead
Point students to the 'good first issue' labels or documentation tasks listed in the project they analyzed, and ask how these roles support the project.
Assessment Ideas
After the Gallery Walk and Comparison Chart activities, present students with the scenario: 'Two developers overwrite each other’s changes in a shared file. What tool could have prevented this, and how?' Ask students to write a one-sentence answer identifying Git or version control and its function in resolving conflicts.
During the Case Study Analysis activity, pose the question: 'You found a bug in a popular open source app. What steps would you take to report or fix it, and what are the benefits and risks?' Facilitate a class discussion focusing on contribution pathways and personal investment, using the case study as a reference.
After the Comparison Chart activity, ask students to list two key differences between open source and proprietary development, focusing on collaboration, access to code, and licensing. Collect responses to identify gaps in understanding for targeted review.
Extensions & Scaffolding
- Challenge: Ask students to research a real-world open source project’s contribution guidelines and propose a non-code contribution they could make.
- Scaffolding: Provide a partially completed Comparison Chart with one row filled in as an example before students begin.
- Deeper exploration: Have students interview a local developer or open source contributor about their experience and present findings to the class.
Key Vocabulary
| Version Control System (VCS) | Software that tracks changes to files over time, allowing multiple developers to collaborate on a project and revert to previous states if needed. Git is a common example. |
| Repository (Repo) | A central storage location for a project's files and its entire revision history. In open source, these are often hosted on platforms like GitHub or GitLab. |
| Fork | A personal copy of another user's repository. Developers often fork a project to make changes independently before proposing them back to the original project. |
| Pull Request (PR) | A formal request to merge changes from a developer's branch or fork into the main project repository. It initiates a discussion and review process. |
| Open Source License | A legal document that grants users rights to use, study, change, and distribute software and its source code for any purpose. Examples include MIT, GPL, and Apache licenses. |
