This report is a summary of the effects of the Michigan Teacher Excellence Program (MITEP) on me as a science educator. The first chapter is a report of an action research project jointly authored with two other science teachers participating in the MITEP program titled “Station Activities and Misconceptions in the Chemistry Classroom.” The second chapter is a reflective essay evaluating the impacts of the MITEP experience on my teaching skills and practice, knowledge of science education and science education research, and leadership skills. The most significant impacts were a dramatic increase in my earth science content knowledge, a deeper understanding of inquiry-based teaching methods, and an expanded professional network of science educators.

The first chapter consists of an action research report submitted by Rebecca Joyce, Kari Luckett, and Claudia Witt as part of the Action Research class taken through the Michigan Teacher Excellence Program (MiTEP) during the winter of 2013. The research involved the use of stations to address student misconceptions in urban high school chemistry classrooms. Chapter two contains a personal reflection on the MiTEP program and how it has affected teaching strategies/practices, personal confidence, and professional relationships.

Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the common practices of graduate students in their biophysics weekly research group meetings. I recorded notes on observations and conduct interviews with all participants of the biophysics research group for a period of eight months. I apply the theoretical framework of Communities of Practice to distinguish the cultural norms of the group that cultivate physics expert practices. Results indicate that physics expertise is specific to a topic or subfield and it is established through effectively publishing research in the larger biophysics research community. The participant biophysics research group follows a learning trajectory for its students to contribute to research and learn to communicate their research in the larger biophysics community. In this learning trajectory students develop expert member competencies to learn to communicate their research and to learn the standards and trends of research in the larger research community. Findings from this dissertation expand the model of physics expertise beyond the cognitive realm and add the social and cultural nature of physics expertise development. This research also addresses ways to increase physics graduate student success towards their PhD. and decrease the 48% attrition rate of physics graduate students. Cultivating effective research experiences that give graduate students agency and autonomy beyond their research groups gives students the motivation to finish graduate school and establish their physics expertise.

Matematiken är en abstrakt vetenskap. Laborativt arbete med konkret material sägs kunna överbrygga glappet mellan abstrakt och konkret. Denna kvalitativa studie syftar utforska vilka möjligheter och begränsningar lågstadielärare erfar kring konkret material. Resultatet visar att en vanlig uppfattning bland lågstadielärare är att konkret material besitter den positiva egenskapen att stötta elever i alla åldrar och nivåer i arbetet med att utveckla matematisk förståelse. Detta genom att konstruera inre bilder av matematiken hos eleverna, vilka sedan kan stötta eleverna på vägen mot matematisk abstraktion och generalisering. Arbetssättet tycks också kunna väcka intresse, nyfikenhet och lust att lära matematik samt bjuda in till rikare möjligheter till kommunikation jämfört med läroboksfokuserad undervisning. Dock har valet av konkret material betydelse. Negativa faktorer som uppmärksammats är att leklust riskerar ta fokus från matematiken samt att duktiga elever särskiljer laborativ matematik med konkret material från "riktig" matematik i läroboken. Dokumentationen av arbetet kring det konkreta materialet är dessutom tidskrävande. En slutsats som dras är att laborativt arbete med konkret material inte ensamt kan stå som bas för elevers matematiska utveckling. Däremot kan arbetssättet kombineras med lärobokens färdighetsträning och matematikdiskussioner och tillsammans bidra till fördjupad förståelse genom att eleverna i ett varierat arbetssätt tillåts möta matematikens olika uttrycksformer.

Recibido 02 de setiembre de 2011 • Aceptado 23 de febrero de 2012 • Corregido 21 de marzo de 2012 La enseñanza de las Matemáticas se ha visto influenciada por la presencia de ciertos estereotipos que han determinado el comportamiento y afectado el rendimiento del estudiantado en dicha disciplina. Diversas investigaciones han señalado la relación de inequidad que hombres y mujeres poseen respecto a las matemáticas y la responsabilidad que el profesorado tiene en su construcción. Por tal motivo se plantea la necesidad de llevar a cabo acciones concretas que permitan la construcción de relaciones de equidad en dicha disciplina, basadas en los principios de respeto, solidaridad y ayuda mutua entre los géneros.
