FOSS in Courses The resources referenced (books, sites on FOSS) were wonderful and are essential to develop a serious, sustained FOSS effort on campus Considerations regarding the sequence to build a FOSS synergy on campus
1. Most important - develop/identify welcoming activities which have low threshold - encouraging students to progress in small steps over time is essential.
2. Use the coding learned in class as the baseline for needed FOSS skill development. Several FOSS skills could be introduced within the class as a means to highlight opportunities.
3. Hold workshops to support collaborative effort on FOSS projects. These workshops could roughly follow the POSSE model. Students would be exposed to the considerable opportunities available - in an area of their interest.
4. Develop a more concerted structure to attain some FOSS achievement. Do not want to send the students off on their own to be successful or fail. Perhaps a summer course, an extended weekend workshop (8 hrs) or a week long (x2?) adjunct to existing courses.
5. Most important - FOSS should be seen as a vital thread to all courses and not as a set of activities "over there".
6. Open Hatch Comes to Campus (OHCTC) and Jessica McKellar provide basis to begi introduction of FOSS.
7. How to best construct sessions for guidng and skill development? use the resources listed on [1] Directions, Q2. Need to review the resources for clarity and consistence for supporting student activities. Can they follow thread of activities from FOSS materials or classes to make progress.
8. The discussions in Directions, Q1 were excellent.
9. There are broken links in http://teachingopensource.org/index.php/Teaching_Materials_Catalogue, curating references would be great first step to avoid rework for all participants. The resource provide a very solid foundation.
POSSE Part C Assignment [4-7 Sep 2015] Part 4 FOSS in Courses Planning Important goals would incentivize and encourage the students that they CAN contribute to FOSS as a matter of course and that the mechanism to do so is fairly straightforward. Many students have a service oriented nature and willingness to extend their growing CS skills to assist others - the incentive exists. The current low level of student FOSS participation, even for skilled students, suggests that small scale steps leading to completion to participation , perhaps as a part of a course, may prove illuminating and fruitful. The next sustaining step is to arm the students with solid understanding of the tools to create and submit.
The steps to date within POSSE have helped a tremendous amount to foster specific and useful resources as well as steps towards gaining some proficiency, then through effort and revisit, competency and mastery. The basic CS and programming skills for the students are acquired through the college curriculum. The steps to contribute and a sense of competence in FOSS participation is the purpose of the two workshops below.
Introductory Workshop (setting foundation)
PREPARATION
1. Prerequisite knowledge: Skills, knowledge for typical CS0 student -> CLI skills
2. Select specific bugs, features which can be developed/fixed within a short time, to serve as success events for students
3. Set up VM for consistent tools and steps for students
PRESENTATION 1. Work through the sources of open source products, much as was done with POSSE activities. For my college, due to small numbers and desire to remain focused, converging initially will on 1-2 projects to work on collaboratively will be valuable. Completing the effort leading to a pull request (2-4 times) is important as the student adds value to the community effort. 2. Parse Intro to FOSS (Activity A) into 60 minute presentation. Provide post-workshop reading recommendations and questions to elicit most important points from readings. 3. Underscore the inevitably and value of being "Productively Lost" 4. Introduce HFOSS as a baseline for helpful opportunities. 5. Introduce git in small sense and use as a basis to clone, fork and submit pull request 6. Teach the presentation with another CS faculty, to serve as observer and identify recommendations to improve. This CS faculty is not primarily (or at all) a presenter - provides basis to refactor workshops.
Applied Workshop 1 (baby steps) PREPARATION 1. After students gain a sense of FOSS, ask that they identify a project, together, to work on for a short time. 2. Work through any problems from above and ensure all students in AWS1 can step through git in meaningful way - not simply watching videos
PRESENTATION 1. Ask students (using PP practices) to identify "fixable" bugs or features or contributions. 2. Review the 50 list - make sure the students are aware that other means of contribution exist - keep appetite whetted 3. Ask for 2 pull-request submissions within workshop period
