作为光路的能量流线:教学分析(Energiestromlinien als Lichtwege:Eine didaktische Analyse)
Energy flow lines as light paths: a didactical analysis (Energiestromlinien als Lichtwege: Eine didaktische Analyse)
摘要:
对波茨坦大学中学生关于光的概念的访谈分析表明,许多学生对光有确定性的看法。关于这些结果的模型的能量流线,最近在教学文献中讨论,是特别感兴趣的。根据这个模型,光被假定为沿着能量流线作为轨迹移动。在能量流线模型的分析中,研究了四个教学维度(教学内容、内部结构、当前相关性和未来意义)。结果表明,在学校物理课上讨论这个模型可以增加学生关于光的模型的元概念知识。另一方面,这可以促进确定性概念和量子力学的玻姆解释。但问题仍然存在:光的性质真的应该被描述为决定性的吗?
英文摘要:
Analyses of interviews with secondary school students about their conceptions of light at the University of Potsdam indicate that numerous students have a deterministic view of light. With regard to these results the model of energy flow lines, which has been discussed recently in the didactical literature, is of special interest. Following this model, light is presumed to move along energy flow lines as trajectories. In an analysis of the model of energy flow lines four didactical dimensions (didactical content, internal structure, present-day relevance and future significance) are investigated. It can be shown that a discussion of this model in physics at school can increase the meta-conceptional knowledge of the students about the models of light. On the other hand, this can promote deterministic conceptions and the Bohm interpretation of quantum mechanics. But the question remains: Should the nature of light really be described as deterministic?
