Ep98 – How Traditional Grading is Less Accurate Than Standards-Based Grading

Handouts are available below.

 

Big Idea

In the world of assessment, just because teachers assess standards using rubrics and not content using traditional grading methods (ie. points scored on a test) doesn’t make Standards-Based Grading (SBG) any less effective. In fact, SBG is meant to assess things that traditional grading doesn’t typically address – such as science skills like communication, application, and analysis. In fact, a traditional grading system would struggle with assessing skills accurately.

 

Episode Notes

Here are a couple of big ideas from the video:

  1. As imperfect as a rubric in SBG may appear, rubrics do a fairly accurate job at assessing standards – if the rubric is defined well. The key thing, always, is to define our rubrics in a detailed and fair way: “detailed”, so we can distinguish each level clearly, and “fair” in that our expectations at each level matches the grade level.

  2. On a rubric (ie. proficiency scale), a proficient is considered a “low A” while an extending is considered a “high A”. Both are A’s.

  3. If we tried to score a standard using traditional grading, how many points would we assign? We could assign 4 points – similar to a 4 level rubric – but the problem there is that a student who got proficient would be getting a 75% (3 out of 4) – a low B in our system, which doesn’t quite denotes a “complete understanding” that is associated with Proficient.

  4. If we decide to assign more points to assess standards via Traditional Grading – for example, make the question out of 10 marks -then we’d have to distinguish between a 6 and a 7 and a 7 and an 8 and an 8 and etc. This becomes more of a headache.
