From my perspective, assignments are graded to help students understand what they know and what they need to learn. On Powerschool, grades are categorized to help you understand yourself as a learner. Each quarter (and any other time you’d like) I’ll provide a summary of how students are doing in chemistry’s three major areas: lab work (30%), conceptual knowledge (30%) and problem-solving (30%). The last 10% of each quarter's grade is reserved for a long-term individual project.
More details on grading can be found here.
It is your responsibility to find out what you have missed. Missed work should be made up a timely fashion, usually within a week. Tests are to be made up before the next unit test. Whenever practical, students who miss only a day should check iCal for homework and be ready for the next day’s class. Students who choose to take vacations during school time are required to make up all work missed and get their own notes on any new material. Alternative assignments may be given, at my discretion, if the nature of the work (such as a team assignment) precludes making up the exact work missed.
Un-graded practice work isn’t accepted late. The due dates represent when we’re discussing the work, and its either done or not done at that point. Graded work will lose 5% per class day. (Quarter projects have special rules.)
There are always special circumstances that can override these rules, such as an away game that got back very late or opening night of the musical. Students are encouraged to talk to me about their special needs for extensions.
Students are also asked to be realistic about their schedules: if you don’t have 30 minutes/day to devote to this course then this might not be the best place for you.
