Chapter 6 Community development roles
Our lessons are intended to be teachable by any certified Carpentries Instructor with the appropriate domain experience and background knowledge. Lessons should also be appropriate for learners at different institutions, and not require specialized local or institutional knowledge. Our lessons attain this broad usability by virtue of being the product of many people at different institutions around the world who work together in different roles to create, test, and iteratively improve and update lesson materials.
No one is perfect! Lesson materials should be read and tested by at least one person other than the original author before being released for use by the broader community in beta pilot workshops. If a lesson has more than one author, co-authors can review each other’s content. Community members can also serve as reviewers. A reviewer commits to carefully reading and testing all code for a lesson or set of episodes and leaving detailed feedback for lesson authors to correct any errors or other issues found. This feedback is provided as issues and/or pull requests (PRs) in the lesson’s GitHub repository (we’ll explain all of that soon!). Authors modify the lessons based on reviewer feedback to ensure the lesson is bug-free, all code runs as expected, exercises are appropriate and test only the concepts being taught, and in general that the lesson is ready to be delivered to learners in a beta pilot workshop.
Reviewers will also check to be sure the lesson complies with our our accessibility requirements.
Don’t worry - this review stage is not the only point at which lessons will receive feedback. Our collaborative lesson development model ensures that Instructors and other community members will continue to engage with the lesson materials at all stages of their development and provide near real-time feedback to keep the lessons in good shape for as long as they are actively being taught!
Reviewers do not need to have any particular domain background or tool expertise. In fact, we recommend including reviewers who are complete novices either the tool being taught by the lesson and/or the lesson’s target domain. This can help overcome authors’ expert awareness gap.
Reviewers should also include people from different geographic regions and cultural and linguistic contexts than the lessons’ authors. If all of a lesson’s authors are based in the UK, for example, there should be at least one reviewer from outside the UK, and ideally from a non-majority English-speaking area. Ensuring that lessons are reviewed by people from a variety of cultural and linguistic contexts helps us to avoid colloquialisms, culturally-specific references, and other issues that might make our lessons less accessible to a global community. You will likely need one or two reviewers for every two hours of lesson content. A four-hour (half day) lesson should have at least two to four reviewers.
6.3 Lesson Maintainers
Lesson Maintainers are essential for the long-term viability of a lesson. As a lesson is taught, new Instructors and learners identify potential places for improvement - whether correcting a typo, simplifying code, or suggesting a significant shift in the narrative of a lesson. Maintainers proactively monitor their lesson’s GitHub repository to make sure that PRs and issues are addressed in a timely manner. Maintainers also play a vital role in communicating with contributors, ensuring that our community lives up to its ideals in welcoming and appreciating contributions from everyone - from first-time contributors to long-time members of The Carpentries community.
People acting as Maintainers should be experienced with the tool that is being taught in the lesson, ideally using it daily or weekly in their own work. In addition, they should have experience working in a relevant domain related to the lesson materials and/or experience working with GitHub and the other technologies we use to create and host our lessons. Each lesson will have at least two Maintainers, and it’s ok for one Maintainer to have domain experience and another to be more comfortable with the technical aspects of lesson maintenance.
6.3.1 Maintainer recruitment, requirements and time commitment
It’s a good idea to recruit at least four Maintainers per lesson, as our community members are volunteers and may have fluctuating levels of time to commit to this role. Having a larger team of Maintainers ensures you’ll always have at least one or two active Maintainers at any given time.
Maintainers commit to a specific set of duties, and go through a short onboarding process to familiarise them with the social, technological, and curriculum-specific elements of lesson maintenance. This onboarding is available as a written curriculum and in future may be made available as a video recording, however, if time allows, we recommend running onboarding for your Maintainer group via synchronous video-conference. Getting everyone in the same virtual room for these discussions creates a sense of community and will make it easier for your lesson Maintainers to work together. Information about how to run a synchronous Maintainer onboarding, including email templates and scheduling information, is available in The Carpentries Handbook.
Once your Maintainers have been onboarded, they will join The Carpentries full Maintainer team. This team meets monthly to share skills, exchange ideas, and get suggestions from each other around challenging issues and pull requests in their individual lesson repositories. The minutes for these meetings are stored in the Maintainer Resources repository. Meeting times and information about how to stay in touch with the Maintainer team is available in The Carpentries Handbook.
A lesson should have at least three onboarded Maintainers before it enters the beta pilot workshop phase. Before that time, lesson feedback and edits will generally be managed by the lesson authors.
6.4 Curriculum Advisors
Curriculum Advisors provide high-level oversight, vision, and leadership for a curriculum and guide large-scale updates. Unlike Maintainers, who are responsible for the day-to-day work of keeping lessons stable and teachable, Curriculum Advisors maintain a broader perspective on the state of the field and make strategic decisions about major changes to a lesson, for example, updating the technology being taught to take into account major advances in the field or changing the dataset used in the lessons to appeal to a broader group of learners.
A Curriculum Advisory Committee (CAC) is composed of 5-8 people with significant domain expertise who represent the breadth of the field that a curriculum is intended to reach. For example, the Data Carpentry Geospatial CAC includes researchers in ecology, limnology, environmental sciences, and sociology, along with university staff leading institutional GIS education efforts. Multiple career levels are represented, from PhD candidates at the end of their graduate work, to mid-late career professionals. At least one member of the CAC should be actively teaching in the field, so they can bring a practical perspective about what skills students and early-career researchers need. Lesson Maintainers may also serve as Curriculum Advisors, but most Curriculum Advisors will not also be Maintainers. Curriculum Advisors commit to a minimum one-year term, but may serve multiple terms. A CAC should include members from multiple geographic regions and cultural and linguistic contexts to ensure that the curriculum meets the needs of our global community.
A Curriculum Advisory Committee meets virtually approximately twice a year to discuss and make decisions about proposed large-scale changes to the lessons within their curriculum. These proposals may be initiated by community members, including Maintainers, or by members of the CAC. The CAC communicates their recommendations back to the Lesson Maintainers and provides consulting and support to Maintainers in implementing proposed changes.
Ideally, a Curriculum Advisory Committee should be assembled in the initial stages of lesson development, before materials start to be drafted. The CAC can then provide high-level guidance, including defining the learning objectives and core content for the curriculum and selecting an appropriate dataset that will speak to a broad group of learners. However, we recognize that lesson development may be part of a grant or other structure with requirements that are incompatible with putting together a CAC at such an early stage. If a curriculum will be included in the official Carpentries lesson stack, there must be a Curriculum Advisory Committee in place at the time of its first publication. The CAC should meet regularly for as long as a curriculum remains active.
6.5 Beta Pilot Instructors
A new lesson or curriculum is often taught for the first time locally at the organization that houses the lesson authors. This can be an opportunity to troubleshoot organizational or technological issues with the lesson, and should certainly be done if resources allow, but is not a sufficient test of the lesson’s broader teachability. It is always easier for the creator of a set of curricular materials to use those materials, but more difficult to communicate all of the relevant details to enable others to deliver the curriculum efficiently. In order to ensure that our lessons are able to be taught by all appropriately experienced certified Instructors, a lesson should be beta piloted at least twice outside of the institution in which it was developed, ideally in two different countries. Because lessons at this stage are expected to still have some technical and flow issues, instructors for these beta pilot workshops should be certified Carpentries Instructors who have previously taught at least two Carpentries workshops. Instructors with this level of experience will be more prepared to troubleshoot issues that arise during the workshop, and more likely to provide useful feedback after the workshop. Beta pilot instructors may be lesson reviewers, Maintainers, Curriculum Advisors, or any Carpentries community member other than lesson authors. In fact, recruiting beta pilot instructors who are already playing active roles in the lesson is likely to be fruitful, as these people are invested in bringing the lesson to maturity. For two beta pilot workshops, you will need at least four instructors. Lesson authors should plan to meet virtually with pilot instructors before the workshop to answer questions and provide any technical help with setup.
Carpentries lessons are designed to be teachable by any certified Instructor with the appropriate domain experience. In many cases, there will already be Instructors with the necessary background in our community. To help these Instructors prepare to teach the new materials, we recommend preparing an onboarding video to introduce the structure of the lesson, the dataset used, and any technical specifics that make this lesson different from other lessons Instructors are likely to be familiar with. Onboarding videos should be made available on The Carpentries YouTube channel with accurate (not auto-generated) subtitles. For inspiration, check out the existing onboarding videos in our Curriculum Onboarding playlist. To raise awareness of your curriculum, you can also schedule themed Community Discussions around your lesson.
If your lesson reaches a new domain which isn’t well represented in The Carpentries community, and you would like to build capacity for teaching your lessons within The Carpentries, get in touch with email@example.com.
