This chart is difficult to read at first. We almost always see a gray fog come over peoples’ eyes when we first introduce it. But it is the best way we know to show real changes in learning on the day they happen! This is because the chart shows the changes in relation to days, and in what order they occur, over a long period of time. These are some of the most important changes to capture in learning behaviors.
Most charts and graphs show scores on composite questions on tests that can only be administered a few times per year. The scores are measured in relation to the general population or some other composite. The Celeration chart is showing scores on a segment of a skill, and you are only compared to yourself, in terms of speed and accuracy of your response.
You can project your future. If it is taking you an average of 3 days to pass a skill or story, and there are 30 skills/stories to master in a grade, you can project how long it will take to perform at that grade level if you continue to pass each skill or story at the same speed.
