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.
The adoption of the Next Generation Science Standards means that many educators who adhere to model-based reasoning styles of science will have to adapt their programs and curricula. In addition, all practitioners will have to teach modeling, and model-based reasoning is a useful way to do so. This brief offers perspectives drawn from Lehrer and Schauble, two early theorists in model-based reasoning.
ISE professionals should find this paper useful in understanding how scientists view the nature of science (NOS). Through interviews, the researchers have enabled a view of science as a flexible, creative and continually developing knowledge enterprise, in contrast to the regimented, experiment-driven scientific method that is most often taught in schools. The authors believe that teaching authentic NOS will certainly aid in enthusing students to learn science and take initiatives in scientific problem solving.
This study, conducted in New Zealand, is an analysis of the questions that students in their final year of high school were anticipated asking, and asked, during a visit to a biomedical research institute. The analysis highlights, along with the interview findings, the ways in which students developed an understanding of biomedical research, saw science as a process, and acknowledged a commonality of values between themselves and the scientists. This study will be of interest to ISE educators who facilitate interactions between students and scientists and who organize opportunities for
Educators have long been urged to facilitate inquiry as a way of enhancing learners’ understanding of science beyond that of basic concepts and skills. But in what ways do educators themselves understand the nature of inquiry and specifically the key terms of hypothesis and experiment? In this study, the authors report on a study examining 12 secondary-school teachers’ understanding of inquiry and related terms, and also their use of such practices in their everyday teaching. The findings indicate that ambiguity exists amongst teachers regarding key terms in contemporary reform documents.
To acquire skills associated with decision-making on socioscientific issues, students need to understand the concepts of risk. Teaching about risk involves acknowledging the uncertainty and limitations of scientific knowledge. This study explores the ways in which risk may be addressed in science education.
This paper describes a study designed to investigate whether fiction can help students to develop their opinions on socio-scientific issues. The findings suggest that fictional accounts can be effective, but the study did not investigate the quality of the reasoning underlying the opinions, nor their longevity.
In this study, the authors describe a conceptual framework addressing culturally based ways of knowing, and provide a brief description of their efforts to design a community-based summer science program with a Native American tribe using this framework. To address the call to attract culturally diverse students to STEM fields, the authors advocate supporting students in their navigation of multiple and perhaps conflicting epistemologies, and using the student community as resources to be built upon, rather than pushing them toward replacing their personal epistemologies with canonical
Socioscientific issues bridge science and society. As such, they are open to multiple viewpoints and inherently associated with morality. This paper presents the findings from a year-long study designed to enhance students’ moral sensitivity so that they are better able to recognise and negotiate the moral arguments embedded with socioscientific issues (SSIs).
In this seminal paper from 2001, the researcher posits sociocultural perspectives as a useful theoretical and methodological lens for examining science education. The paper examines the types of questions that are asked when applying a sociocultural lens to the science classroom and usefully references several different bodies of work within the sociocultural tradition. The research paper discusses the ways in which non-sociocultural perspectives have positioned science and the processes of learning science in ways that privilege dispassionate rationality in a way that may not be easily
This paper describes a Saturday science program for K-2 students designed to enhance their understanding of the nature of science. Teaching strategies were used to explicitly address all the elements of NOS—the role of empirical data, the distinction between observation and inference, the creative processes of science, the subjective (theory-laden) nature of research, and the tentative (though robust) NOS knowledge.
This paper contributes to a growing body of literature examining ways of supporting teaching and learning of socio-scientific issues (SSIs). Comparing experiences in two schools—one with a monoethnic student population, the other multiethnic—the study finds that both groups of students struggle with meaningful engagement in SSIs.
