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.
Integrating technology with reformed-based science instruction that facilitates student inquiry can be challenging for teachers. Campbell, Longhurst, Wang, Hsu, and Coster propose a professional development model that helps teachers use the latest technologies to engage students in authentic science practices.
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 can technology be used to support inquiry in the classroom? In this study, Rehmat and Bailey probe the effects of a science methods course for preservice elementary teachers that explicitly includes technology integration. The preservice teachers in this course broadened their definition of classroom technology, increased their technology use, and gained a more positive outlook on technology integration.
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.

Teachers’ beliefs are key in determining the effect of professional development (PD) initiatives. In this study, teachers’ self-efficacy beliefs about their ability to teach science and the amount of PD they received were found to be significant and positive predictors of student achievement.
This study examines the effectiveness of a teacher professional development program that sought to address the integration of Native American students’ cultures with classroom science teaching. Informal science education practitioners interested in reaching non-dominant populations can use this study as evidence that professional development focusing on cultural points of intersection has a positive effect.
Drawing on a survey of 454 teachers, Penuel, Fishman, Yamaguchi, and Gallagher found several components of professional development (PD) that predicted implementation of an earth science curriculum. They determined that the coherence of the PD effort and the provision of content instruction were the most important factors determining whether or not teachers implemented the new curriculum.
The findings of this study suggest that pre-service teachers do not adequately understand key concepts in climate science. They see the greenhouse effect as a problem, not as a natural phenomenon. By contrast, they inaccurately see chlorofluorocarbons as key contributors to global warming. The practical implication is that training programmes for teachers—and indeed for other learners—need to explain key terms more effectively. These programmes must also emphasize the links among causes, consequences, and solutions.
Museum educators rarely experience ongoing training. They tend to rely on their past experiences of teaching and learning to guide their interactions with learners. Allen and Crowley describe the implementation of a new school trip program that challenged museum educators’ beliefs. The program involved a five-month process of reflective practice and the iterative testing of student-centered, inquiry-based facilitation approaches.
This article reports on a case study of two middle school science teachers who took part in professional development designed to help them enact culturally relevant pedagogy in their classrooms. The long-term and community-oriented aspects of the professional development seemed to play a vital role in supporting the teachers’ success.
