The Effect of Professional Development on Middle School Teachers' Technology Integration: An Action Research Study

The Effect of Professional Development on Middle School Teachers' Technology Integration: An Action Research Study

posttest method, students were assessed before and after the semester in which students learned Mechanics or Electricity and Magnetism. In Mechanics, students completed the 2015 AP Physics C: Mechanics practice exam, FCI, and MBT assessments; in Electricity and Magnetism, students completed the 2015 AP Physics C: Electricity and Magnetism practice exam, BEMA, and EMCA assessments. During each semester, I implemented Modeling Instruction with AP Physics C: Mechanics or Electricity and Magnetism content (see Appendices A, B, and C for further information). Each unit of content began with a paradigm laboratory, providing an experience for students to create an initial model. Students moved through the Modeling Cycle by performing practice problems and completing more laboratory activities, adding new information to their initial model. Near the end of each unit, students used a whiteboard to summarize their learning into a fully-constructed model; students shared their whiteboards to compare fully-constructed models. Students finished each unit with a written summative assessment containing multiple-choice and short answer problems; some units also had students perform a summative laboratory practicum. The cycle was repeated with a new unit of content, leading to the development of models in Mechanics and Electricity and Magnetism.

CALCULUS REMEDIATION AS AN INDICATOR FOR SUCCESS ON THE CALCULUS AP EXAM

CALCULUS REMEDIATION AS AN INDICATOR FOR SUCCESS ON THE CALCULUS AP EXAM

There are also certain biases that may have detracted from greater student success on the AP Calculus AB exam. During the eight years of the remediation implementation, the impact of Common Core at the elementary level may have had a negative impact on students’ level of understanding on basic concepts, which would lead to gaps in the mathematical foundation that students develop. These gaps follow the student to high school and may detract from the overall understanding of concepts in prerequisite classes for Calculus as well as in the Calculus class itself. During the last five years of this study the seat time that students had in class dropped by ten minutes per school day, or for a cumulative amount of about two weeks of class time. Less time in class means less time to understand the material presented. Along with the remediation program, these positive and negative biases must be looked at as possible factors that may affect the change in success for the group of students over the eight years of this study.
