I have a growing dissatisfaction with the execution of CS222, and I think this is in stark contrast to my other course, CS315: Game Programming. 315 is based entirely on studio-based learning: it is project-oriented learning to the nth degree, with all 25 students collaborating with me and external stakeholders on a real project. Perhaps the best way for me to express the difference between these two courses is to show what I did in the last meetings of these two courses.
In CS315, where students are in their 10th week of the project:
- Worked on research for 5-10 minutes while the students had their "daily" stand-up meetings.
- Got new markers for the lab where many of the students work.
- Found paper for the printer in the lab so that students could print up some signs on lab usage, which they proposed to the department chair as official statements.
- Helped a student in the lab, who is in my other class, with his project and talked about D&D a little with him and some 315-ers.
- Gave some tips on how to deal with in-game dialog box images and text, facilitating conversation between members of different teams.
- Looked over a group's shoulders and recommended a refactoring to a monstrous method.
In CS222. where students are in the second week of a six-week project:
- Talked for 5-10 minutes about the importance of voting, the history of public education and its role in forming an educated electorate, and the difference between indoctrinating patriotism and respecting freedom. (It is election day.)
- Showed past and current examples of an MSF-style risk matrix and Scrum backlog, explaining that the teams may use either one--or something else--as long as they are deliberate in their decision and reflect on it, and they can write a reflection on it later. (5-10 minutes)
- Gave a walkthrough of how I use Google's guava library. This took about 10-15 minutes, partially due to unexpected system problems with Eclipse, probably related to the distro change and multiple Eclipse installs I currently have on my netbook.
- The remaining 35 minutes was used by teams to evaluate each others' physical prototypes. As teams evaluated each others' interface designs, I posted some links to the course Web site. Only one group asked me for feedback on their design, and then others came to ask about other things. The best of these was the question of whether I thought a specific project was even worth pursuing, and I explained (to the student's satisfaction) that it wasn't me they should ask, but their prospective users.
315 is a joy. It is by and large an amazing experience to watch students learn to work together and learn from each other in a wholly legitimate way, a sort of organized chaos.
In 222, by contrast, I keep finding myself talking much more than I want to. It's not usually until I'm done that I realize how long I have been talking. We can take the guava libraries as an example: when I first learned about them, I was floored, and I wished that someone had shown them to me ages ago. In my mind, it would have only taken someone's showing a minimal example for me to see why I should be using this in all my Java projects. Yet, when I showed the students what I do with it, I got very little excitement from them. Was it because they do not have the perspective I have to realize what a useful library it is, or was it a failure of my presentation? These two are hard for me to disassociate, but the fact remains that maybe the whole thing would have been better organized as a workshop than a lecture. This is not without its own complications, not the least of which is the amount of planning that's required for minimal payoff.
Since day one in 222, we've had assignments due twice a week, at each meeting. This idea was gleaned from the SIGCSE mailing list as a way of ensuring students are doing the reading and keeping up. I will be teaching the course next semester, and I need to re-evaluate this structure in light of the students' lack of programming prowess: I'm not sure they're seeing the forest for the trees on issues of design, since many still struggle with basic program structure. Be that as it may, right now, the students are working on a six week project, delivered in two three-week increments. I am continuing to have them read items from Effective Java, but now instead of relating them to old projects or other experiences, they are relating these to their current project. For example, they are currently reading about minimizing the scope of variables (Item 45), and I asked them to evaluate their current project--in its current state--in light of this design idea. It's too early to know if this is positively impacting student learning, but my fear is that I might be giving them too many diverse ideas for them to deeply learn from their project experience. As soon as a student sees the homework as busywork rather than a learning experience, it loses almost all value to the student.
Maybe writing this, then, has helped me to see the problem: some students are not seeing the tips in Effective Java as the brilliant ideas they are, and so the well-intentioned assignments become busywork instead of learning experiences, and so both the assignment and the project suffer, rather than the synergy I try to promote. If that's true, then it becomes a problem of motivation management, the perennial problem of education. I think that I will scheduled time in class, perhaps next Tuesday, in which to engage students in a discussion of this whole process. I get the feeling that many of them do not feel like they can give me an honest evaluation of the class in person, so I may have to find a way to get them brainstorming, maybe a SWOT analysis, and come up with communal ideas.
As always, no answers, but this blog is not a place for answers: it's a place to try to hunt down the questions, and the questions within questions. As always, I'm open to ideas from the community. My plan for now is to maximize the learning in the time we have left this semester (about four weeks), and then use Winter Break to do a more significant analysis of the structure, goals, and delivery of 222.
