I am preparing for my second year of implementing standards-based grading (SBG) in my 5th and 6th grade math course. I was thrilled with the benefits of using SBG with my students but found that I need to do more parent education. While I present a summary of SBG at my school's Parents' Weekend, not all parents attend or remember the details. I am, therefore, trying to develop a resource that I can link to in my email signature that will be accessible year-round.
I am looking for resources, accessible to parents, that summarizes why SBG is beneficial for students. The ideal source would be short (1-2 pages), outline the motivations for abandoning traditional grading processes, discuss the concept of growth mindset, and include details of how parents can support the SBG process.
I am happy to read through a big collection of articles, so please share anything you think might be pertinent.
Update: I have found some articles that are close to what I am looking for, but are not quite right. In general, most of the articles that I have found tend to spend too much time outlining a specific system for employing SBG or tend to be much too long. For example
1) Miller - "A Better Grading System" This article is too long for my needs and spends significant time describing a SBG system
2) Marzano and Heflebower - "Grades That Show What Students Know" Similar issues to Miller's article above: too long and too much detailing of how a specific grading system would work.
