@Nighthawk, Thank for the answer. These are 3rd years with reasonable experience in coding. However, they have never worked on an ongoing project and never modified/worked on code that they did not write themselves (or at least that was not written by their peers). The learning objectives are to exercise their (newly gained) knowledge about build systems, lower-level software dependencies and C/C++ programming in the context of a Computer Systems/Operating Systems course. Clearly, Haiku fits well into these objectives.
This is the first we are doing this, so we're giving them plenty of time (about 2 months) to get familiar with an open source project and get a bug fix or enhancement approved. Some issues in the "Easy" list are good, but they are not enough in number.
Please let me know if more context information is needed.
PS: Yes, I have searched Trac for bugs, but the list is HUGE and there are many irrelevant or old bugs. The community might be able to give some tips to better direct my efforts
