随着基础教育课程改革的深入进行,研究性学习一直是教育研究者关注的焦点。在化学学科教学中如何将研究性学习理念、观点运用于教学实践,有效地实施研究性学习,急需化学教育研究的深入探讨。基于此,笔者在研究性学习理念的指引下,依据创设情境—假设、活动探究—总结、评价—迁移练习的新课程理念,设计了“金属 Na 与 Cu-SO_4溶液能否发生置换反应”的实验探究活动,教学中取得
With the deepening of basic education curriculum reform, research learning has always been the focus of education researchers. How to apply research-oriented learning concepts and perspectives to teaching practice in chemistry teaching and effectively implement research-based learning requires an in-depth discussion of chemical education research. Based on this, under the guidance of the concept of research-based learning, the author designed a new course concept based on context-hypothesis, activity-inquiry-summarization, and evaluation-migration practice to design whether or not the metal Na and Cu-SO4 solution can undergo displacement reaction. "Experimental inquiry activities, obtained in teaching
