For my graduate thesis at Harvard, I conducted a research study looking at the movable alphabet. I was frustrated by the literacy assessments we were required to give our students in public Montessori school. It just seemed completely inappropriate to ask a preschooler to try and spell words by writing them down. I mean, preschoolers are just learning how to hold a pencil and recognize what letters look like! It is a big leap to go from there to writing spelling quiz words.
So, I designed a research study to look at a different kind of assessment. One that could still reveal the young child's developing ability to build words but without stressing them out with the added difficulty of handwriting those words.
This short video gives you a little more detail about that research study. The full study can be found on the Harvard Digital Scholarship platform.
