This study examined the validity of the Draw-A-Scientist Test (DAST), which is commonly used to capture students’ perceptions of scientists. Findings suggest that the DAST is not valid as a sole measurement. The originally identified stereotypical traits are no longer widely held by students.
Why do some people move into science while others move away? Salehjee and Watts collected 12 personal biographies that provide rich descriptions of the different paths—direct or more wavering—that individuals follow. The implications of this study suggest that the informal science sector needs to “keep doors open” for individuals at transition points.
Wallace and Brooks examined the culture of an elementary science education methods course conducted in a summer science camp, along with the professional identity development of the preservice teachers during their participation in the course.
How do people make sense of conflicting beliefs? Although Gottlieb & Wineburg’s paper is about highly educated professionals reading history, informal science educators will recognize similar issues when working with people who hold beliefs incompatible with scientific ways of understanding the world. “Epistemic switching” was a way of considering criteria for truth, reliability, and validity according to one belief system or another. Rather than simply believing or excluding ideas as people who held to only one value system, the people with multiple, competing affiliations actually more
The new standards posit that “scientific argumentation,” in which students use data to argue from evidence, is a key practice for student science learning. However, a mismatch in expectations about the purpose of classroom discussions can inhibit productive forms of argumentation. Berland and Hammer compare forms of class discussions to identify how best to support students’ engagement in argumentation.
