Days or parts of days when teachers work and students have time off are related to as Teacher Inservice or Professional Development. Teachers use the time for such tasks as improving their teaching strategies and techniques or planning with colleagues for improvements in the curriculum. Current research indicates that the methods teachers use to deliver the instruction is as much or more important than having knowledge of the curricular content. It is no longer adequate to use one strategy to present lessons and expect all students to learn the same way. It may seem like teachers have a lot of Professional Development time, but be assured that they are using the time to complete necessary and required tasks that will enhance their ability to teach your children.
