Grading a Lab Report

Just finished grading a lab report. Even with a carefully written and colleague-reviewed rubric, this is not a trivial event. This is the best rubric I’ve had to date and the grading gets easier. MCCPS Science Rubric The students are beginning to hand in reports in the same format, and that makes grading easier, but I have identified the key points that I need in each report. I have also asked them for feedback on the rubric: clarity, material difference between grading levels, and completeness. The objective is to improve their use of the scientific method, their lab skills, including observation and data collection, and their science writing skills. I’m recording this at a 30% level right now, that is, this is weighted at 30%, rather than 10 or 60%. For example, homework is recorded at a 10% level. Once I’m satisfied that they are competent, I’ll start recording it at a 60% level.
