尽管多年来的研究和实践受到化学教育研究的启发,但最近的一份报告显示,美国中学教学与当前国家改革的努力并不一致。缓解这种差异的一种方法是关注教学概念的变化,其前身(更高的自我效能和教学不满),以及其机制的微妙之处(同化和适应)。在这项研究中,我们调查了参与者(N = 35)谁完成了我们的专业发展计划被称为VisChem研究所(VCI)的最终反映。研究结果显示,约翰斯通三角形以及证据、解释和模型有助于激发自我效能感较高的VCI教师的教学不满。此外,VCI教师如何吸收和/或适应基于改革的化学教学理念的问题化传统的假设,拓宽了新理论的应用,是密切相关的介绍世界各地的化学学习环境。在中学和高等教育水平的化学教学和研究的影响和建议进行了讨论。
Despite years of research and practice inspired by chemistry education research, a recent report shows that US secondary instruction is not aligned with current national reform-based efforts. One means to mitigate this discrepancy is focusing on pedagogical conceptual change, its precursors (higher self-efficacy and pedagogical discontentment), and the subtleties of its mechanisms (assimilation and accommodation). In this study, we investigate the final reflections of participants (N = 35) who completed our professional development program known as the VisChem Institute (VCI). Our results show that Johnstone's triangle as well as evidence, explanations, and models can be conducive for stimulating pedagogical discontentment among VCI teachers who exhibit higher self-efficacy. In addition, how VCI teachers assimilate and/or accommodate reform-based chemistry teaching ideas problematizes conventional assumptions, broadens application of novel theories, and is germane to introductory chemistry learning environments across the world. Implications and recommendations for chemistry instruction and research at both secondary and tertiary levels are discussed.
