Examining the impact on TPACK and knowledge subcomponents in dually certifying secondary mathematics teacher candidates with a Computer Science add-on endorsement

This study examined the impact on secondary mathematics teacher candidates (TCs) TPACK knowledge and knowledge subcomponents of a two-course sequence based on the high school Advanced Placement (AP) Computer Science Principles (CSP) course leading to add-on teaching credentials for Computer Science (CS). We further examined the outcomes of Praxis II preparation modules on CS content knowledge of the preservice TCs compared to inservice teachers seeking an additional teaching field of CS. Our results indicate strong findings on the Technology Knowledge (TK) and TPACK factors for TC participants compared to their peers, as well as higher Praxis II scores than inservice teachers. We discuss the findings and implications for CS teacher certification embedded within other secondary teaching disciplines.
