I think a rubric has to be set by the educator. We definitely know more in terms of what we want the students to learn as facilitators of learning That said, it may be something to consider having students evaluate their own work based on a set of criteria. For example, I need to be able to provide my students a clear set of instructions on what needs to be included on their lab report (abstract, data, calculations, graph, discussions, etc.), including things that they need to check before submission (units, significant figures, precision, accuracy, etc.). They could, on their own, evaluate their work. On my part, once I have their work graded based on the actual rubric set, if the student did not do well, there can be a discussion in terms of why they did not earn the grade they gave themselves during their self-evaluation. I have not done this but I am thinking of starting it in the Fall…I don’t know know if students will really make time to perform a self-evaluation but it can be a really good conversation starter and make the student really responsible for their learning. They need to realize in the end that I don’t make the grade, I just add the grade based on the work shown (or not shown, which is often the case).
