Day 44 – A SBGers Nightmare

Mon. Nov 4, 2013

Today marks the end of the first quarter.  A day that is dreaded by all Standards Based Graders living in a points based world.  I have spent restless days and restless nights trying to figure out how to turn all of the data I’ve collected about how well the students know chemistry or physics into a single symbol to represent learning.

Look at all this great data I have about each student and what their strengths and weaknesses are.  I can also easily analyze what I have done a good job of giving students opportunities to succeed.

How does this become an A, B, C, D or F?  Is it subjective?  Do I just look and give it the “eye test?”  Can I be biased?  How can I make it objective and fair?

I defiantly do not believe I have the perfect system, I also don’t think any single letter grade system is perfect.  But since it needs to be done I had to come up with something.  Here is the formula I use:
Letter Grade

In words:  Students start at a 50% for having a pulse.  The number of core goals mastered divided by core goals possible makes up the next 25%, Intermediate goals are 15%, and finally the Advanced goals are 10%.

Using Activegrade you can export the Gradebook into Excel and then run this formula.  It takes a little bit to get set up the first time, but then it gives me a percentage for each student.

I teach high school Chemistry and Physics using Arizona State University's Modeling Method. The school I teach in is Bloomer HS in Northwest Wisconsin. I've been using the Modeling Method for 7 years now and have just recently begun using Standards Based Grading as a way to assess my students learning.
