摘要
本研究通过测查、观察、访谈、实物分析等方法对某大班幼儿在六次教学活动中对光影概念认识的发展进行了跟踪,结果表明:幼儿对影子的外部特征获得较早,对光线在影子形成中的本质作用,光源、物体、影子三者之间的关系,以及光线沿直线传播获得较晚,且未理解影子产生的本质原因——光线受到物体阻挡形成影子。同时,幼儿的自主探究、同伴间的交流、教师基于幼儿原概念的问题情境的创设都是影响幼儿光影概念①转变的可能因素。
We tracked a 6-year-old child＇s understanding of the conception of light and shadow in 6 teaching activities by testing, observing, interviewing, and analyzing his drawings. The result is that this child recognized shadow＇ s outward features first, and then he began to recognize the effect of light on shadow forming, the relation between light source, object, and shadow, and noticed the fact that light travels in straight lines. But he did not understand the reason of shadow forming--light is blocked by object and then shadow appears. Meanwhile, creating questionable environment on the basis of children＇s preconception, children＇s communication with others and self-exploring are possible factors influencing children＇s conceptual change of light and shadow.
