Connections Between Science Teachers' Professional Development Preferences And Their Teaching Practices And Beliefs, Jessica Marie Wayson Jan 2017

Connections Between Science Teachers' Professional Development Preferences And Their Teaching Practices And Beliefs, Jessica Marie Wayson

Honors Program Theses

The effect of professional development preference, in relation to its effect on teacher practices and beliefs, has not been well studied. In order to better understand this dynamic, a nationwide online survey was developed and sent to secondary science teachers. The findings of this survey indicate a relationship does exist, but only within specific practices. During analysis, teachers were grouped by preference of professional development type including collaboration, reflection, conducting research, and professional development (such as conferences and workshops). Significant differences emerged from each group and implications for effective professional development practices will be addressed.

Secondary Mathematics Educators And Coaches' Role In Providing Motivation, Reggie Schulte Jan 2017

Secondary Mathematics Educators And Coaches' Role In Providing Motivation, Reggie Schulte

Honors Program Theses

The compatibility between learning goals for students and mastery-oriented athletes makes sense based on my experience in both fields. I have often heard from coaches that it is important to “embrace the process” or “trust the process.” This same idea can be applied to a mathematics secondary classroom by praising effort and embracing the struggle that comes along with having a conceptual understanding of mathematics. As a future educator and coach, it is exciting, and to be honest somewhat scary, to know that I can a great effect on what my students believe they are able to achieve. After conducting …
