Michael Tan 《Cultural Studies of Science Education》2012,7(3):653-657
In response to Goff, Boesdorfer, and Hunter??s article on the use of a multicultural approach to teaching chemistry and the nature of science, I forward this critical reflective essay to discuss more general curriculum aspects of the relationship between the nature of science and science education in school contexts. Taking a social realist perspective, I argue for a more nuanced understanding of the role of epistemology and ontology in science classrooms, and for a reconsideration of the role of knowledge in science classrooms. 相似文献

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for researcher-developed comprehension measures. Few studies (n = 4) reported standardized measures of reading comprehension, which indicated medium effect sizes. The majority of study treatments (n = 13) utilized strategy instruction related to main idea or summarization. 相似文献

Adults with learning disabilities (LD) attending adult basic education, GED programs, or community colleges are among the lowest performers on measures of literacy. For example, on multiple measures of reading comprehension, adults with LD had a mean reading score at the third grade level, whereas adults without LD read at the fifth grade level. In addition, large numbers of adults perform at the lowest skill levels on quantitative tasks. Clearly, significant instructional challenges exist for adults who struggle with literacy issues, and those challenges can be greater for adults with LD. In this article, the literature on adults with LD is reviewed, and evidenced-based instructional practices that significantly narrow the literacy achievement gap for this population are identified. Primary attention is given to instructional factors that have been shown to affect literacy outcomes for adults with LD. These factors include the use of explicit instruction, instructional technology, and intensive tutoring in skills and strategies embedded in authentic contexts. 相似文献

Parents play a key role in developing their children's academic motivation, and parents of children with gifts and talents also may face additional parenting challenges that are less commonly faced by parents of average‐ability learners whose needs are more readily met in the school setting. School psychologists may be charged with addressing these issues, despite having little or no training on the needs of families of high‐ability learners. We use the lens provided by the self‐determination theory of motivation to consider how social–environmental climates created by parents can promote or impede the academic motivation of students with gifts and talents. © 2012 Wiley Periodicals, Inc. 相似文献

Being bullied is associated with a psycho-social maladjustment during childhood. One hitherto largely overlooked correlate is disrupted classroom concentration. Using data collected from 364 9–11-year-old children attending seven junior schools in the UK, we tested a model in which children’s perceived safety in two contexts (classroom and playground) and their perceived relationship with their teacher were hypothesised to mediate the association between being bullied and classroom concentration. Two analytical approaches to testing multiple mediation – product of coefficients and bootstrapping – supported the model. None of the mediation effects was moderated by sex but they were by year; in all cases the mediation effect was stronger in the older children than in the younger children (but still significant among the latter). These data suggest mechanisms through which bullying might have its effects on classroom concentration. The practical and theoretical implications are discussed. 相似文献

The purpose of this paper was to explore innovative entrepreneurship and to gain insight into the educational practices and experiences that increase the likelihood that a student would graduate with innovative entrepreneurial intentions. To this end, we administered a battery of assessments to 3,700 undergraduate seniors who matriculated in the spring of 2007; these students attended one of five institutions participating in this study. Results showed that, after controlling for a host of personality, demographic, educational, and political covariates, taking an entrepreneurial course and the assessments faculty use as pedagogical strategies for teaching course content were significantly related to innovation intentions. Implications for higher education stakeholders are discussed. 相似文献

This study investigated how the instruction of argumentation skills could be promoted by using an online argumentation system. This system entitled ??Cognitive Apprenticeship Web-based Argumentation?? (CAWA) system was based on cognitive apprenticeship model. One hundred eighty-nine fifth grade students took part in this study. A quasi-experimental design was adopted and qualitative and quantitative analyses were used to evaluate the effectiveness of this online system in measuring students?? progress in learning argumentation. The results of this study showed that different teaching strategies had effects on students?? use of argumentation in the topics of daily life and the concept of ??vision.?? When the CAWA system was employed during the instruction and practice of argumentation on these two topics, the students?? argumentation performance improved. Suggestions on how the CAWA system could be used to enhance the instruction of argumentation skills in science education were also discussed. 相似文献

The Bureau of Labor Statistics projects an increase in Natural Resource Management (NRM) jobs within the next 10?years due to baby-boomer retirements and a 12% increase in demand for these occupations. Despite this trend, college enrollment in NRM disciplines has declined. Even more critical is the fact that the soon-to-be-majority Hispanic population is underrepresented in NRM disciplines. The goal of the present study was to determine if an in-residence, two-week, summer science program for underrepresented minorities would not only increase interest in science, actual science knowledge, and perceived science knowledge, but also have an overall impact on underrepresented minority students?? decisions to attend college, major in a scientific discipline and pursue a career in science. During a four-year period, 76 high school students participated in a Science Agricultural Summer Experience (SASE) in Northern New Mexico. A pre/post science-knowledge exam and satisfaction survey were administered to participants. We demonstrate that participants improved significantly (p?<?.05) in all areas measured. In particular, comfort with science field and lab activities, science knowledge and perceived science knowledge were enhanced after exposure to the program. Students not only found science exciting and approachable after participation, but also exhibited increased interest in pursuing a degree and career in science. Of the 76 SASE participants within graduation age (n?=?44), all graduated from high school; and 86% enrolled in college. These findings suggest that the implemented SASE initiative was effective in recruiting and increasing the confidence and abilities of underrepresented minority students in science. 相似文献

Short-term study abroad is the fastest growing area of international education and there is increasing interest in the role of modified applications of this form (e.g. faculty-led, field/environmental, and/or educational travel) in influencing global citizenship. Using an empirical database of over 650 students registered for a study abroad course in sustainable development offered in Australia and New Zealand, we explore the effect of short-term educational travel programs on environmental citizenship. We also identify differences among key student characteristics (past study abroad experience, gender, and program destination) in influencing citizenry. Results show that participation in the educational travel program significantly moderates (decreases) the difference in environmental citizenship scores for first-timers (vs. those with past experience in study abroad) and program destination, but increases the difference in environmental citizenship for males vs. females. Implications for destination image and national brand marketing of environmental-oriented educational travel programs are discussed. 相似文献
