Exercise 4

An educational psychology was interested in the way that children learned to write. She asked three teachers to each use a different technique when teaching hand writing to children. She then measured the improvement in handwriting in the children two months after the implementation of the different teaching techniques. She anticipated that Posture Focussed would be a better technique than Tracing Letters, and Continuous Cursive Writing would be a better technique than Posture Focussed. Are there differences in the level of improvement in writing between these teaching techniques?
