Some teachers do not like the idea of letting students do a "redo" on an assignment. It can, if done carefully, have a positive impact on students learning and the culture of the classroom.
SBG standards based grading
One of the hurdles that holds teachers back from implementing standards-based grading is the gradebook. Most schools use an electronic learning management system. Some of these platforms have added customizations to support recording learning targets rather than point values. Even with the upgrades, teachers can benefit from some 'hacks' to assist in recording student achievement.
As a chemistry teacher considering the switch to standards-based grading, you might be wondering how lab reports work in a system that is not based on points. With lab reports, you just need to decide whether you are grading chemistry content skills, scientific communication skills, or both.
A few months ago I reported that I was involved in a pilot standards based grading (SBG) program. My experiment in SBG started well but required some “tweeks” along the way.
