The development and implementation of a teacher education model in environmental science education for Indian Certificate of Secondary Education (ICSE) schools.

摘要

This research study is concerned with the teaching of Environmental Science in the ninth and tenth grades of ICSE schools in Mumbai, India and the development and implementation of a new teacher education model. The instructional strategies practiced by the teachers were investigated using a questionnaire, semi-structured interview schedule and classroom observation. Based on these data, a new model of teacher education was developed with the help of a small cohort of teachers. The rationale for the model was that it should be a non-prescriptive framework that provided a coherently organized, concise guide for environmental education teachers that incorporated modern perspectives on content knowledge, effective pedagogical practices including constructivist approaches and active learning, and a set of guidelines for effectively integrating pedagogy with science content knowledge. The model was in the form of a two-way matrix, with the columns providing the pedagogy and the rows indicating the content knowledge. The intersections of the columns and rows to form individual cells of the matrix yielded a synthesis of pedagogical content knowledge (PCK). The model was discussed with the participating teachers, who prepared revised lesson plans using the model and delivered the lessons, which were observed by the researcher.;On using the model, the teaching became more student-centered, as the teachers strove to include constructive and inquiry-based approaches. The use of technology enhanced the effectiveness of the lessons and teachers evaluated the students on all three domains of learning (i.e., affective, cognitive, and psychomotor). Most teachers agreed that it was possible to use the model to plan their lesson and implement it in the classroom; however, they needed to put in more time and effort to get used to a change in their teaching methodology. There is no doubt that teacher professional development is a long process and change does not occur immediately. This model is a transitional one and future development of the model may include more emphasis on further refinements in an approximation toward a thoroughgoing constructivist classroom practice, including a more transactional approach than used here.
