Chart 1: I inserted progressions into spreadsheets but these were too broad to be effective.
Chart 2: I took on specific writing progression and using SOLO made a chart which students could identify themselves on and see their next step. The downfall with this chart was when embedding a Google Spreadsheet into a blog the size adjustments are not very smooth and it is too difficult for students to do it themselves.
Chart 3: Using the same information as the previous chart I make this chart in Google Presentations. This worked much better because the process of embedding a presentation into a blog is easier and students can easily adjust the size to fit the layout of their blog nicely. The bonus of this chart being embedded into the blog means that student can add links to pieces of writing as evidence and they don't need to update their blog because it updates automatically. Also another bonus is that these links work when embedded on their blog so any viewer of their blog to click on and see their writing evidence.
Chart 4: After presenting this chart and working through it with a number of students I quickly discovered that I needed to make each step very clear and give more detail. For example I needed to state how many sentences a couple is. So my final process has been to amend each steps and this is the final chart of which I am using with my students at this stage.
