理论性知识探究式教学模式与策略初探——以化学《质量守恒定律》为例

The Model and Strategies of the Inquiry-Based Teaching of Theoretical Knowledge —— Taking Chemistry Course Law of Conservation of Mass as An Example

探究式教学是针对传统注入式教学存在的弊端而提出的。化学理论性知识探究式教学必须结合其所具有的概括性、抽象性和较强的逻辑性与严密性等知识特点展开。首先教师要创设一定的问题情境引发学生的认知冲突,从而激活知识的意义;其次,教师要设计一定的探究活动,帮助学生转变原有的认知,从而使学生体验知识建构的过程;再次,教师要组织学生开展有效的交流与讨论,引导学生阐明解释自己的观点,从而形成学生之间知识的有意义互动;最后,教师要及时开展评价与总结,引导学生反思完善新的知识,从而进一步转变观念。

Inquiry-based teaching is given birth to overcome the pitfalls of traditional spoon-feeding teaching ; The inquiry-based teaching of theoretical knowledge should be implemented with full consideration given to such characteristics of knowledge as generality , abstractness , logicality and rigor . At the initial stage of teaching , teachers should create certain question situation to trigger learners ’ cognitive conflicts so as to activate knowledge ;Next , some inquiry activities should be designed to help learners to change their existing cognition and to experience the process of knowledge construction ;Then , effective communication and discussion should be organized for learners to express their opinions and to have meaningful interaction through knowledge exchange ;Finally , teachers should make evaluation and summaries to guide learners to reflect and consolidate newly acquired knowledge , so as to further develop their cognition .
