Adults’ Learning about Science in Free‐choice Settings     

Léonie J. Rennie  Gina F. Williams 《International Journal of Science Education》2013,35(8):871-893

This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science‐related experiences in free‐choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and its communication by scientists. The three studies involved samples of visitors to an interactive science centre, visitors to a traditional natural history museum, and attendees at a series of public lectures, each given by an expert scientist in human genetics. Pretest and post‐test data collected by parallel questionnaires indicated that, despite the different nature of their experience in the three different settings, participants became more positive about the value of science and the work done by scientists and their ability to communicate with the public. At all venues, however, participants became less scientific in their thinking about the nature of scientific knowledge, becoming more likely to believe it to be infallible. The consistency of these findings was surprising, and participants’ changed views about the nature of scientific knowledge were unexpected. Possible explanations for theses outcomes were suggested in terms of participants’ reasons for attending the venue, the nature of their engagement, and the non‐controversial ways in which the exhibitions and lectures were structured. The findings suggest that the educational role of free‐choice settings should be considered carefully, particularly with regard to the representation of science.  相似文献   

‘We’re from the generation that was raised on television’: a qualitative exploration of media imagery in elementary preservice teachers’ video production     

Michael T. Hayes  Gina Mikel Petrie 《International journal of qualitative studies in education》2013,26(4):499-517

In this article the authors present their analysis of preservice teachers’ video production. Twenty‐eight students in the first authors’ Social Foundations of the Elementary Curriculum course produced a 5‐ to 10‐minute video as the major assignment for the class, interviews were conducted with six of the seven video production groups and the videos were analyzed with regard to the interviews and theories of visual culture. The authors suggest that in the video products and in the production process the students exhibited a cultural logic of media imagery. The particular logics of audience and entertainment served as a concealed organizing principle for how the students thought about their videos and the processes involved in making them. Embedded in this logic was an overarching concern that their work occupy a public space, thus troubling the boundaries of consumption and production that frame how we consider the role media culture plays in the processes of human meaning‐making.  相似文献   

The Interactive Effects of Personal Achievement Goals and Performance Feedback in an Undergraduate Science Class     

Krista R. Muis  John Ranellucci  Gina M. Franco  Kent J. Crippen 《Journal of Experimental Education》2013,81(4):556-578

The authors explored whether manipulating feedback influenced cognition, motivation, and achievement in an undergraduate chemistry course. They measured students’ (N = 250) achievement goals, test anxiety, self-efficacy, and metacognitive strategy use at the beginning and end of the semester. After completing the first set of questionnaires, students were randomly assigned to 1 of 4 conditions: (a) control, (b) mastery feedback, (c) performance-approach feedback, and (d) combined mastery/performance-approach feedback. In each condition, students received a raw performance score for each weekly quiz they completed online and, for the treatment conditions, additional feedback reflective of that specific feedback condition. Results provide evidence for the multiple goals perspective (specialized pattern) wherein performance-oriented feedback was beneficial for some outcomes, whereas mastery feedback was beneficial for other outcomes.  相似文献   

Doctoral ‘orphans’: nurturing and supporting the success of postgraduates who have lost their supervisors     

Gina Wisker  Gillian Robinson 《高等教育研究与发展》2013,32(2):300-313

Much research into doctoral student-supervisor relations focuses on developing positive interactions. For many students, however, the research experience can be troubled by breakdowns in communication and even the loss of the supervisor(s), turning the student into a doctoral ‘orphan’ and impacting on their academic identity and ability and confidence in producing a sound doctoral-level contribution to knowledge. Our work with a range of UK- and internationally-based doctoral students looks specifically at reasons for supervisor loss and/or absence and the students' experience of being doctoral ‘orphans’ in terms of identity, confidence and progress. In focusing on those who achieve successful completion, it suggests the need for institutional and community support and highlights the development of effective strategies leading to ownership, empowerment and emotional resilience.  相似文献   

Sport-based physical activity intervention on body weight in children and adolescents: a meta-analysis     

Kyungun Kim  Gina Ok  Soeun Jeon  Minsoo Kang 《Journal of sports sciences》2017,35(4):369-376

Controversial results reported in past research pertaining to the effectiveness of sport-based physical activity interventions on weight loss. The purpose of this study was to assess the impact of sport-based physical activity intervention on body weight in children and adolescents using a meta-analysis. Academic Search Complete, Education Source, ERIC, Medline, ProQuest, PsycINFO and SportDiscus databases were searched from January 2000 to April 2015. Eighteen studies met following inclusion criteria: sport-based intervention studies; subjects aged 6–18 years; reported body weight; published in peer-reviewed journals written in English. The mean intervention duration was 17.72 weeks. The overall effect size (ES) was 0.52 (Cohen’s d (ES) = 0.52, 95% CI = 0.08, 0.95, P = 0.021), using a random effects model. Moderator analyses results showed that the Q statistic for the sport type (individual sport or team sport, Qbetween (Q_b) = 14.52, df = 1, P = 0.001) and diet control (Qbetween (Q_b) = 8.85, df = 1, P = 0.001), explained the heterogeneity of ESs. Our study showed that there was a moderate overall effect of sport-based physical activity intervention on body weight reduction. The team sport type (ES = 1.05, 95% CI = 0.44, 1.66) and diet control group (ES = 0.84, 95% CI = 0.26, 1.41) appeared to be more effective in reducing body weight.  相似文献   

Online Political Discourse: Exploring Differences in Effects of Civil and Uncivil Disagreement in News Website Comments     

Gina Masullo Chen  Shuning Lu 《广播与电子媒介杂志》2017,61(1):108-125

An experiment (N = 272) demonstrated that disagreement—either civil or uncivil—may have a chilling effect on the public discourse vital to a deliberative democracy. Both forms of disagreement—in comments posted on a news story about abortion—caused negative emotion and aggressive intentions. However, only uncivil disagreement led people to respond back uncivilly and indirectly led to greater intention to participate politically, if it aroused aggressive feelings. Findings support extending face and politeness theories to the computer-mediated space of online commenting. Results are discussed in relation to the impact on the public discourse.  相似文献   

Investigating English reading comprehension growth in adolescent language minority learners: some insights from the simple view     

Jeannette Mancilla-Martinez  Michael J. Kieffer  Gina Biancarosa  Joanna A. Christodoulou  Catherine E. Snow 《Reading and writing》2011,24(3):339-354

The development of reading skills in language minority (LM) learners, particularly during the middle school years, remains unclear despite the increasing need for educators to serve this rapidly growing population. In this study, the English reading comprehension growth of middle school LM learners was investigated using a longitudinal design and the simple view of reading as a theoretical framework. Students were assessed at four time points between fifth and seventh grades on standardized measures of listening comprehension, word reading, and reading comprehension. Individual growth modeling revealed that both listening comprehension and word reading assessed in fifth grade predicted the elevation of students’ developmental trajectories in reading comprehension. However, neither skill predicted students’ growth in reading comprehension, and there was no significant variation across children in growth rates, indicating that students in seventh grade remained on a trajectory established in fifth grade. The implications of the slowing rate of reading comprehension development during the middle school years are discussed.  相似文献   

Language, social behavior, and the quality of friendships in adolescents with and without a history of specific language impairment   总被引：1，自引：0，他引：1  

Durkin K  Conti-Ramsden G 《Child development》2007,78(5):1441-1457

Language is drawn on extensively in friendships but has received scant attention in the developmental literature. This study compared friendship quality in 16-year-old adolescents with and without specific language impairment (SLI), testing the extent it is predicted by individual differences in social behaviors and language ability. Participants were 120 adolescents with SLI and 118 typically developing (TD) adolescents. After considering the effects of nonverbal IQ and prosocial and difficult behavior, language measures were found to be associated with friendship quality. The TD participants enjoyed normal friendships, whereas the participants with SLI were more likely to exhibit poorer quality (although 60% experienced good quality of friendships). Longitudinal analyses identified early language difficulties as predictive of poorer friendship quality in adolescence.  相似文献   

Prospective English teachers’ views on the physical environment, human resources, and program of their departments     

Esra Eret  Ahmet Ok 《Asia Pacific Education Review》2010,11(4):533-540

The quality of teacher education, in general, is affected from a number of variables such as physical environment of the institutions, instructor quality, the curriculum implemented, administrative support, and others. As the input of the system, the perspectives of the students on those variables also influence the direction and the quality of the education taking place in the colleges of education. Regarding this, the purpose of the present study is to identify and compare the perspectives of fourth-year English Language Teaching students on the physical environment, human resources, and the program of three ELT departments at three different state universities. As part of the survey research design, the questionnaire was administered to totally 278 prospective English Teachers from the ELT departments at state universities in Ankara. The results of the study, unlike the past research on the issue, presented that the prospective English teachers had positive views on the instructors and program generally; however, they stated problems on the physical environment of their departments. Moreover, there were significant differences in students’ views on the physical environment, resources, and its sub-dimensions. The students from the institution, which was renovated before the study, had more positive views on their department than the others. The results suggested it might be useful to reevaluate and reconsider the current conditions of the English language teacher education in relation to the departments’ human resources, program and especially the physical environment.  相似文献   

Personal digital assistant-based drug information sources: potential to improve medication safety.     

Kimberly A Galt  Ann M Rule  Bruce Houghton  Daniel O Young  Gina Remington 《Journal of the Medical Library Association》2005,93(2):229-236

OBJECTIVES: This study compared the potential for personal digital assistant (PDA)-based drug information sources to minimize potential medication errors dependent on accurate and complete drug information at the point of care. METHODS: A quality and safety framework for drug information resources was developed to evaluate 11 PDA-based drug information sources. Three drug information sources met the criteria of the framework: Eprocrates Rx Pro, Lexi-Drugs, and mobileMICROMEDEX. Medication error types related to drug information at the point of care were then determined. Forty-seven questions were developed to test the potential of the sources to prevent these error types. Pharmacists and physician experts from Creighton University created these questions based on the most common types of questions asked by primary care providers. Three physicians evaluated the drug information sources, rating the source for each question: 1=no information available, 2=some information available, or 3 = adequate amount of information available. RESULTS: The mean ratings for the drug information sources were: 2.0 (Eprocrates Rx Pro), 2.5 (Lexi-Drugs), and 2.03 (mobileMICROMEDEX). Lexi-Drugs was significantly better (mobileMICROMEDEX t test; P=0.05; Eprocrates Rx Pro t test; P=0.01). CONCLUSION: Lexi-Drugs was found to be the most specific and complete PDA resource available to optimize medication safety by reducing potential errors associated with drug information. No resource was sufficient to address the patient safety information needs for all cases.  相似文献
