An examination of the relationship among science teaching actions, beliefs, and knowledge of the nature of science.

摘要

Scholars in science education advocate curriculum and instruction practices that reflect an understanding of the nature of science. This aspect of school science is an important component of scientific literacy, a primary goal of science education. Considering teaching as a thoughtful profession, there has been a growing research interest on the issue of the consistency between teacher beliefs and actions. Yet, the self-evident assumption that teachers' beliefs about the nature of science will impact on their classroom teaching actions has not been justified.; The purpose of this study was to examine the relationship between science teaching actions and beliefs about the nature of science. Defining teacher beliefs as a broad construct, the researcher tried to examine not only teacher's cognitive understanding about the nature of science but also teachers' affect as well as actions with regard to the nature of science. Guiding research questions were as follows: (a) what are the teachers' beliefs about the nature of science; (b) how do the teachers, pedagogical actions reflect their beliefs about the nature of science; and (c) what are the other referent beliefs that mediate the teachers, pedagogical actions within a local school culture.; The methodology of this study was an interpretive, qualitative approach that included multiple sources of data, interviews, classroom observations, and instructional materials. Six science teachers from a secondary school located in a rural area of the southeastern US were chosen by convenience. The cross-case study and the grounded theory study designs were adopted as the data analysis process. The constant comparative analysis method was used to generate the emerging themes for this study.; This study revealed a gap between these teachers' personal beliefs of the nature of science and the concepts of the nature of science suggested by many researchers. These teachers' personal beliefs about the nature of science have been constructed based on their science teaching and learning experiences and as a result are closely related to their belief about the nature of school science. These teachers teaching actions reflected their own personal beliefs about the nature of science within the interaction of multiple referent beliefs with relation to science teaching and learning.
