Teachers are accountable for progressively higher expectations of performance in their classrooms. With the addition of standards-based teaching and performance testing, today's teachers feel the pressure of implementing quality lessons and curricular units in the classroom within strict time constraints. Not only is the number of qualified teachers in short supply, often they are expected to teach subjects outside their area of primary preparation. Teachers in science and technology classrooms, especially at the elementary and middle school levels, regularly report a lack of confidence in their ability to teach those subjects and seek content-specific professional development opportunities to enhance their classroom success.
