Subject: Re: grading practices/scales
Hi, Thanks for your question to T2T. I find it interesting that there is a lot of interest in assessmnet. We receive lots of questions about assessing student learning. My personal summative assessment (grade assigned) was the following: I always assigned a point scale for a certain activity. If it was homework, it might be a 2. So students could earn a 0, 1, or 2, depending on the quality of the assignment. If it were a quiz, it might be a 6. If it were a test, it might be a 18, and if it were a major test, it might be a 40. This was pretty arbitrary, but it was a judgement call for me about how important assignment was. In my gradebook, I recorded the possible points that could be earned, and then how many points students earned. Then to find the students average, I would add all the numerators and all the denominators, and divided. I also had students keep a running total so they always knew what their average was at any time. >There is a large discrepency in the way the entire staff at my school >handles grades, specifically averaging grades together for an overall >marking period grade.
