Alternative Frameworks in Conceptions of Sound: A Historical Evolution

บทคัดย่อ

This article reviews and discusses the historical development in the scientific
conceptualization. It follows key debates and conceptions of sound through an evolutionary process leading to contemporary understanding of sound related phenomena. It is notable in the article that the raging debates among scientists of ancient Greece to seventeenth century interpreted and understood sound as either a substance or a wave. Consequently, sound related phenomena were explained based on the framework in which they were formulated. However, with evidence from scientific experiments and mathematical deductions, sound was eventually understood as a wave. Moreover, the sound-as-substance framework as shown in the historical development resembles some of students’ preconceptions as demonstrated by numerous studies on conceptions of sound. It is hoped that this review of the historical development in the conception of sound can elucidate the way in which students learn and inform the nature of instructional activities that science teachers can design to promote student learning.
