Making assumptions is an important step in solving many real-world problems. This study investigated whether participants who could solve well-defined physics problems could also solve a real-world physics problem that involved the need to make assumptions. The participants, who all had at least a BA in physics, were videotaped “thinking aloud” while solving three well-defined and one real-world problem and then interviewed about the problem-solving process. All the problems dealt with the same scientific content. The recordings were analyzed to identify similarities and differences in the
At the 1939–1940 New York World's Fair, several thousand boys and girls, all members of a growing national network of high school science and engineering clubs, displayed their science fair projects and conducted live experiments to more than 10 million visitors. Housed in the building sponsored by the Westinghouse Electric and Manufacturing Company, their exhibits depicted a wide range of scientific phenomena. They also represented the conflicting values of science educators and industrialists about the societal worth of science education. In some instances, students' projects and laboratory
This paper reports on a study that employed metacognition and social cognition theoretical frameworks to explore and interpret students' views of their cognitive roles and the nature of the mechanisms that they considered influenced and mediated their learning within small group contexts. An instrumental interpretive case study methodology was used to capture students' descriptive accounts of their Year 11 Biology learning experiences, as conveyed through their recollections and reflections concerning their interactions and roles, perceptions of the learning task, and their learning strategies

This paper discusses conceptions of identity in relation to science education and presents material from a series of interviews and focus groups with graduate students in science and technology. Given difficulties in retention and levels of significant participation by minority students indicated by aggregate data, the issue of race, as it informs critical interactions at a majority research university, is explored in terms of its effects on identity formation. It is argued that we need to look at “real-time” science to see how subtle interactions affect minority graduate students. These
Constructing scientific explanations and participating in argumentative discourse are seen as essential practices of scientific inquiry (e.g., R. Driver, P. Newton, & J. Osborne, 2000). In this paper, we identify three goals of engaging in these related scientific practices: (1) sensemaking, (2) articulating, and (3) persuading. We propose using these goals to understand student engagement with these practices, and to design instructional interventions to support students. Thus, we use this framework as a lens to investigate the question: What successes and challenges do students face as they
This research examined the nature of parent–child conversations at an informal science education center housed in an active gravitational-wave observatory. Each of 20 parent–child dyads explored an interactive exhibit hall privately, without the distraction of other visitors. Parents employed a variety of strategies to support their children's understanding of unfamiliar topics, including describing evidence, giving direction, providing explanation, making connections, and eliciting predictions. Parents' education was associated with both the amount of time dyads spent exploring exhibits and
Nearly 79,000 questions sent to an Internet-based Ask-A-Scientist site during the last decade were analyzed according to the surfer's age, gender, country of origin, and the year the question was sent. The sample demonstrated a surprising dominance of female contributions among K-12 students (although this dominance did not carry over to the full sample), where offline situations are commonly characterized by males' greater interest in science. This female enthusiasm was observed in different countries, and had no correlation to the level of gender equity in those countries. This suggests that

This qualitative study examined the perspectives of African American parents as it pertained to informal science education. The following questions guided this study: (1) What are the desires of African American parents/guardians with respect to informal science programs and experiences for their children?; (2) What happens in Jordan Academy, an enrichment program that has successfully recruited African American students?; and (3) What are the African American parents'/guardians' opinions of the program? We inductively and deductively analyzed classroom observations; academy curriculum; photos
In this study, the instructional effectiveness of the planetarium in astronomy education was explored through a meta-analysis of 19 studies. This analysis resulted in a heterogeneous distribution of 24 effect sizes with a mean of +0.28, p<.05. The variability in this distribution was not fully explained under a fixed effect model. As a result, a random effects model was applied. However, a large random effect variance component indicated that study differences were indeed systematic. The findings of this meta-analysis showed that the planetarium has been an effective astronomical teaching tool
The article discusses how undergraduate science students became docents for "The Genomic Revolution" exhibit at the Fernbank Museum of Natural History in Atlanta, Georgia. According to the article, a docent is one who serves as a connection between the museum and the attendees and acts as an interpreter of the collection for the visitors. Undergraduate students were recruited from schools in the Atlanta, Georgia area including the Georgia Institute of Technology, Emory University, and Spellman College. The docent training program that would cover the genetic principles of the exhibit, the Peer

This article describes an initial attempt to find out students’ perceptions of class visits to natural history museums, with regard to the museum’s role as a place for intellectual and social experience. The study followed up approximately 500 Grades 6–8 students who visited four museums of different sizes, locations and foci. Data sources included the Museum Constructivist Learning Environment Survey (M-CLES), which was adapted from Constructivist Learning Environment Survey, an open-ended question and semi-structured interviews with 50 students. The three instruments highlighted some
