Using Data
Tuesday, December 16th, 2008Yesterday, I gave a workshop for teachers on using data to improve student achievement. This is something that is going to become an increasing part of my work, so I may be blogging about it from time to time. The idea is to cull information about students from a variety of sources, systematically analyze that information in order to identify areas of improvement, and then create an action plan for targeting those areas.
In some cases, the results of careful data analysis can be surprising. So often we jump to conclusions about why students aren’t achieving, or we depend on underlying assumptions that may be based on our own pre-conceived notions. Consider for a moment this piece of student work:
Laugh if you must, but it’s easy to get the wrong idea from only a cursory examination. Further investigation revealed that the child’s mother works at Home Depot, and is here depicted selling snow shovels. And if you only relied on your initial observations and didn’t investigate further, you could be lead astray.
Hopefully, the systematic use of data will allow us to avoid such snap judgements and take a more scientific approach to improving student achievement.
