This study investigates the relationship among (1) college major, (2) knowledge used in reasoning about common health beliefs, and (3) judgment about the accuracy of those beliefs. Seventy-four college students, advanced biology and non-science majors, indicated their agreement or disagreement with commonly believed, but often inaccurate,…

Many topics in introductory astronomy at the college or high-school level rely implicitly on using astronomical photographs and visual data in class. However, students bring many preconceptions to their understanding of these materials that ultimately lead to misconceptions, and the research about students' interpretation of astronomical images…

Nowadays, in the United Kingdom, citizens take for granted clean water pumped directly into their homes, but it was not always the case, and is still not so in many countries. Could people clean water themselves if they had to and what could they then use it for? Would it actually be "clean enough" to drink? The author presents children…

Investigative interviewers seek to obtain complete and accurate accounts of events from witnesses. Two studies examined the influence of instructions about the use of don't know (DK) responses and of clarifying the meanings of DK responses on the quality of responding to questioning. Participants watched a video, and after a delay (Study 1, 30…

Open source software has revolutionized the way people develop software, organize collaborative work, and innovate. The numerous open source software systems that have been created and adopted over the past decade are influential and vital in all aspects of work and daily life. The understanding of open source software development can enhance its…

Sudanese families arriving in Australia bring with them a wealth of language and cultural resources that are currently not recognised by the Australian education system. This paper challenges such a position by investigating the narratives of the Sudanese Australians from a Deleuzian perspective. A Deleuzian perspective in education promotes the…

Although students are enthusiastic when engaging in hands-on investigations, they can find it challenging to make sense of their data and to create explanations using evidence from their investigations. The authors spent a year designing and testing strategies in a science classroom to better assist elementary students in constructing and…

Humor is common and purposeful in most work settings. Although researchers have examined humor and joking behavior in various work settings, minimal research has been done on humor applications in the field of crime scene investigation. The crime scene investigator encounters death, trauma, and tragedy in a more intimate manner than any other…

In this study, we analyzed the correlations between hip flexion power, sprint performance, lumbar lordosis (LL) and the cross-sectional area (CSA) of the psoas muscle (PM). Ten young adults performed two sprint tests and isokinetic tests to determine hip flexion power. Magnetic resonance imaging was used to determine LL and PM CSA. There were…

Skidmore and Thompson (this issue of "Educational Researcher") imply that a graph was changed with the intent to promote more experimental research in education. In this response, the author presents evidence that challenges this implication and concludes that the changed graph does not accurately capture the "declining" trend of experimental…

Piaget (1962) asserted that children stop engaging in pretend play when they enter the concrete operational stage because they become able to accommodate reality and no longer need to assimilate it to their wishes. Consistent also with the views of Vygotsky, discussion of pretend play in developmental psychology is typically confined to early…

This paper defines the terms "hypothesis," "prediction," and "conclusion" and shows how to use the terms correctly in scientific investigations in both the school and science education research contexts. The scientific method, or hypothetico-deductive (HD) approach, is described and it is argued that an understanding of the scientific method,…

This investigation is a secondary analysis of data from a randomized control trial of the PLAY Home Consultation Intervention Program which was conducted with 112 preschool children with Autism Spectrum Disorders and their parents (Solomon et al. in "J Dev Behav Pediatr" 35:475-485, 2014). Subjects were randomly assigned to either a…

This pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers' knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and…

The Next Generation Science Standards (NGSS) are composed of three intertwined dimensions--disciplinary core ideas, science and engineering practices, and crosscutting concepts--that provide a foundation for what students should know and be able to do at various grade levels. The eight science practices outlined in the NGSS are critical components…
