Using DEPTH as a framework for the determination of teacher professional development

This study illustrates the use of the DEPTH model in the development of professional development for secondary teachers of Engineering. In the school context of Western Australia, Engineering is a new upper school subject which will be taught by Design and Technology teachers, the majority of whom have neither taught at this level before, nor taught Engineering content. The multidimensionality of the DEPTH model was particularly appropriate in identifying the range of felt needs of these teachers to address the new curriculum in Engineering.
