Impact of Professional Development on Teachers

The overall quality of LSC professional development increased significantly over time. The most effective LSC professional development programs reflected a design that was conceptualized and implemented as an overall program of work, not as a laundry list of offerings. (Banilower & Shimkus, 2004)

As a result of these professional development experiences:

  • teachers had more positive attitudes about standards-based teaching in mathematics and science;
  • teachers were more positive about how well they understand mathematics/science; and
  • teachers were more positive about their ability to teach mathematics/science content (Heck & Crawford, 2004a).

These findings were significant in both mathematics and science professional development.
