Description
An understanding of the Nature of Science (NOS) remains a fundamental goal of science education in the Unites States. A developed understanding of NOS provides a framework in which to situate science knowledge. Secondary science teachers play a critical role in providing students with an introduction to understanding NOS. Unfortunately, due to the high turnover rates of secondary science teachers in the United States, this critical role is often filled by relatively novice teachers. These beginning secondary science teachers make instructional decisions regarding science that are drawn from their emerging knowledge base, including a tentative understanding of NOS. This tentative knowledge can be affected by environment and culture of the classroom, school, and district in which beginning teachers find themselves. When examining NOS among preservice and beginning teachers the background and demographics of the teachers are often ignored. These teachers are treated as a homogenous block in terms of their initial understanding of NOS. This oversight potentially ignores interactions that may happen over time as teachers cross the border from college students, preservice teachers, and scientists into the classroom environment. Through Symbolic Interactionism we can explain how teachers change in order to adapt to their new surroundings and how this adaptation may be detrimental to their understanding of NOS and ultimately to their practice. 63 teachers drawn from a larger National Science Foundation (NSF) funded study were interviewed about their understanding of NOS over three years. Several demographic factors including college major, preservice program, number of History and Philosophy of Science classes, and highest academic degree achieve were shown to have an affect on the understanding of NOS over time. In addition, over time, the teachers tended to 'converge' in their understanding of NOS regardless of preservice experiences or induction support. Both the affect of different demographics amongst teachers and the 'converging' aspect of their understanding of NOS provide much needed insight for teacher trainers, mentors, and researchers.

The pathway for entering the K-12 classroom as a teacher varies compared to what was once the traditional model of teacher preparation. In this mixed-methods action research study, I explore supporting first year alternatively certified urban and rural intern teachers through a multicomponent distance induction program. The induction model in this study was based on the theoretical framework of Bandura's social learning theory and Wenger's communities of practice. The purpose of this study was to identify the extent in which a multicomponent distance learning induction program impacts first year intern teachers' sense of self-efficacy, understand their successes, their challenges, and to identify how intern teacher evaluations change. Quantitative data included results from a self-efficacy survey and the Student Teaching Assessment Instrument (STAI). Qualitative data was collected through intern teachers' blogs, cadre leader video narratives, and cadre leader STAI narrative responses. Six themes emerged including topics such as building relationships with other education professionals, receiving feedback from the cadre leader, identifying struggles and application of college coursework into the K-12 classroom. Key findings reveal interns are least efficacious in student engagement, relationships with other educators support an intern teacher emotionally and pedagogically, intern teachers struggle with work-life balance, and cadre leaders observed intern teachers as having improved their skills in student engagement, instructional practices, and classroom management. Implications to practice include a structured approach to introducing student engagement, creating a best practices library of video examples, and a pre-orientation (Super Saturday) of topics prior to stepping into the classroom with students.

Description
Pedagogical content knowledge (PCK) has been described as the knowledge teachers' use in the process of designing and implementing lessons to a particular group of students. This includes the most effective representations that make the content understandable to students, together with the preconceptions and misconceptions that students hold. For chemistry, students have been found to have difficulty with the discipline due to its reliance upon three levels of representation called the triplet: the macro, the submicro, and the symbolic. This study examines eight beginning chemistry teachers' depiction of the chemistry content through the triplet relationship and modifications as a result of considering students' understanding across the teacher's first three years in the classroom. The data collected included classroom observations, interviews, and artifacts for the purpose of triangulation. The analysis of the data revealed that beginning chemistry teachers utilized the abstract components, submicro and symbolic, primarily in the first year. However, the teachers began to engage more macro representations over time building a more developed instructional repertoire. Additionally, teachers' developed an awareness of and responded to their students' understanding of learning atomic structure during the second and third year teaching. The results of this study call for preservice and induction programs to help novice chemistry teachers build a beginning repertoire that focuses on the triplet relationship. In so doing, the teachers enter the classroom with a repertoire that allows them to address the needs of their students. Finally, the study suggests that the triplet relationship framework should be revisited to include an additional component that frames learning to account for socioscientific issues and historical contributions.
