Exploring science and mathematics teachers' fidelity of implementation of Project Lead The Way curriculum: a case study on how teachers' knowledge and beliefs influence their enactment of the curriculum

The purpose of the study aimed at gaining a better understanding of how the intended Project Lead the Way (PLTW) curriculum differs from the enacted curricula and what factors impact this. This understanding is important to make the professional development program more meaningful to the immediate needs of the teacher in the classroom. Identifying the factors that contribute to any emerging differences between the curricula helped fill the gap in research on teacher knowledge and beliefs about the use of science and mathematics content in the PLTW classroom. PLTW is an innovative hands-on pre-engineering curriculum designed for K-12 students based on project-based and problem-based learning. It tries to combine math and science principles to present engineering concepts to students in a way that tries to keep up with the rapid changes associated with technology in their everyday world. Multiple case sampling was used to select four teachers based on their years of teaching experience as well as background in science and math. They were interviewed about their knowledge and beliefs about project and problem-based learning. In addition, non-participant observations and teacher beliefs questionnaires were used to triangulate the data for more credible results. A fidelity of implementation rubric was also used to determine how well the teachers were implementing the curriculum. Findings of the study show that there were differences in the way teachers chose to enact the curriculum that were heavily influenced by the curriculum materials, the professional development training and their own personal beliefs about how the curriculum should be enacted. A conceptual model is developed that aims at improving the professional development experiences for the teachers that considers their beliefs.
