Sarah will be student teaching at Lewistown Middle School in Lewistown, PA, during the Fall of 2005, in a seventh grade life sciences classroom.

During her pre-student teaching field experience, Sarah has combined her personality with those of experienced science teachers in order to develop a lively teaching style. She looks forward to her student teaching experience and getting started in her own classroom.

Upon graduation, Sarah will be looking for a teaching position in a life sciences or biology classroom. She hopes to be employed in a school district with a tight-knit network of science teachers willing to try new ways of teaching. She is very excited to begin her role as an educator and looks forward to many rewarding and exciting experiences as a teacher.

After graduating from Penn State, Pamela worked at Norristown Area High School in Norristown, PA teaching ninth grade conceptual physics for three years. She also coached field hockey and lacrosse during that time. Pamela then went on to teach tenth grade biology, eleventh grade health, and twelfth grade environmental science at Multi-Cultural Academy Charter School in Philadelphia for one year. She was also involved in the extended school day and Saturday school programs at that school.

Pamela moved from Philadelphia to San Diego in August 2009. She is currently teaching three different ninth grade science courses: climate change, earth science, and a global studies course titled the Costa Rican environment. She is teaching at King-Chavez High School, a charter school in downtown San Diego. At this school Pamela has carried out a number of innovative laboratory activities and experiments with her students. Active learning and participation are an integral part of her teaching.

Pamela is always on the look out for new adventures in her field, as well as, teacher conferences and workshops to broaden her perspective on science education.
