Abstracts: After <strong>the</strong> concept <strong>of</strong> pedagogical content knowledge (PCK) was introduced by<br />

Shulman, scholars formed <strong>the</strong>oretical frameworks to clarify this construct and make it<br />

constructible through teacher education programs. Ball’s framework divided ma<strong>the</strong>matical<br />

knowledge into subject matter knowledge and PCK, becoming <strong>the</strong> most influential<br />

framework for ma<strong>the</strong>matics education. Consequently, methods courses <strong>of</strong>fered by<br />

schools <strong>of</strong> education changed <strong>the</strong>ir course structure to support <strong>the</strong> development <strong>of</strong> preservice<br />

ma<strong>the</strong>matics teachers’ PCK. However, <strong>the</strong>re have not been sufficient changes in<br />

pre-service education programs for <strong>the</strong> development <strong>of</strong> specialized subject matter<br />

knowledge (SSMK). Considering this need, one teaching module <strong>of</strong> an instructional<br />

technology course emphasizing <strong>the</strong> use <strong>of</strong> Dynamic Geometry S<strong>of</strong>tware (DGS) was<br />

developed. Four lesson activities requiring teachers to use DGS were formed. Following<br />

<strong>the</strong> implementation <strong>of</strong> this course in Fall/2012 in a sou<strong>the</strong>ast research university, a study<br />

was proposed to investigate <strong>the</strong> influence <strong>of</strong> DGS on pre-service secondary ma<strong>the</strong>matics<br />

teachers’ development <strong>of</strong> SSMK.<br />
