We analyzed how two basic electromagnetism textooks approach the concept of electric field. We limited our study to the reasons given in these textbooks for the introduction of the field representation and to how accurate, coherent, and complete these reasons are. Because many times historical reasons are intertwined with textbooks' explanations of physical phenomena, we used the historical evolution of the field representation to guide our analysis. The analysis shows that one textbook mixes up the historical and pedagogical reasons for the introduction of the concept of field. The other one presents a sketch that might lead students to understand the field and the action-at-a-distance views as supplementing each other.  相似文献

This article presents an experimental pedagogical framework for providing technical professionals with practice on writing skills focusing on the development of their metacognitive rhetorical awareness. The article outlines the theoretical foundation that led to the development of the framework, followed by a report of a pilot study involving information technology professionals in a global setting using an online learning environment that was designed based on the framework.  相似文献
