A few weeks ago in Physics 11 I decided to return to my previous SBG scheme. I had started the year using a level scale. The reason was because I wanted to give specific difficulty targets for learning objectives. However, this method turned out to be too confusing, especially for the students. I had the feeling that my students really had only a small understanding of what or how they were assessing their work. On the other hand, the 3 point scale is very clear and easy to assess. While simplicity isn’t the goal for assessment, the assessment has to be understandable.
