小学科学课程里“声音的传播”是小学科学四个领域之一——物质世界的“能量”分支的一个内容,与运动和力、物质与材料等相关领域联系紧密(见图1)。本次研究主要关注小学生对“声音的传播”以及“人耳是怎样听到声音”的具体认识。我们的研究着重针对以下几个方面:了解学生对“声音在传播过程中能量逐渐衰减”的认识;了解学生对“人耳是怎样听到声音”的看法;了解学生对“真空能否传声”的认识;
In primary science curricula, “the spread of sound” is one of the four areas of primary science - one of the “energy” branches of the physical world, linked to fields related to movement and force, matter and materials (see figure 1). This research mainly focuses on the specific understanding of primary school students about the spread of sound and how the human ear can hear the sound. Our research focuses on the following aspects: understanding of students’ awareness of “sound energy attenuation in the process of sound ”; understanding of students “how the human ear is heard ”; understanding of students Vacuum can sound “” understanding;
