指向物理核心素养的分解式实验探究——以“串联电路中的电压规律”实验教学为例

Exploration on Decomposition Experiment Pointing to Physics Core Accomplishment——Take the Law of Voltage in Series Circuits as an Example

初中物理所涉及的探究问题中,有些比较复杂,如果试图仅靠一个实验得出结论,则容易导致学生在探究过程中思维混乱、逻辑不清,最终牵强地得出结论.为了关注学生探究能力的发展、学科核心素养的培养,此时有必要将复杂问题有逻辑、有条理地分解成多个逐层递进的简单问题,以保证在探究逐步深入的过程中,每一步都是有着严密的逻辑和充足的证据.基于这种认识,以人教版"串联电路中的电压规律"为例,提出相应的实验教学改进建议.

Some of scientific problems in middle school physics are too complex to be solved just by a single experiment which could result in illogical thinking and a far-fetched conclusion.In order to develop students′scientific inquiry abilities and physics key competence,it is necessary to decompose a complex problem into several simple problems systematically,which are interrelated and also gradually progressive.Thus,sufficient evidence and strict logic could be ensured in the whole process of inquiry.Here,we take"The Law of Voltage in Series Circuits"as a case to introduce the approach of decomposing complex scientific problems in middle school physics.
