The Impact Of Historical Narratives On Students' Nos Understanding And Science Motivation, Peng Dai

Dissertations

Scholars over the past few years have drawn attention to the enormous potential role historical stories can play in promoting student understanding of issues associated with the nature of science (NOS). Such stories, often referred to as “historical narratives,” are thought to do so by providing a rich historical context within which students are acquainted with how scientists in the past reasoned about scientific phenomena. Klassen (2009) developed a theoretical framework that identifies ten essential elements that must be present to qualify as a historical narrative. Only a few studies have empirically assessed the merits of Klassen’s framework, and in …
