Culturally responsive science teaching is using knowledge about the culture and life experiences of students to structure learning that is conducive to their needs. Understanding what teachers need to prepare them to be culturally responsive is a matter of continuous debate. As the focus of multicultural education ventures farther away from its roots, advocating the civil rights of historically oppressed groups, concerns about the gravity of racial inequity on schooling continues. How will this shift in focus influence teachers’ capacity to accommodate students’ needs resulting from racial inequities in this society, particularly African American students? What knowledge is essential to their effectiveness? This qualitative study examined the instructional practices of two effective middle school science teachers deemed culturally responsive by their administrator on the basis of classroom observations, students’ responses and standardized assessment results. Both teachers’ classrooms consisted primarily of African American students. Grounded theory was used to analyze the teachers’ beliefs and practices in order to identify existing commonalties. Critical race theory was used to identify whether there was any influence of the students’ racial identities on the teachers’ beliefs and practices. The analysis reveals that the teachers’ beliefs and practices were informed by their critical awareness of social constraints imposed upon their African American students’ identities. These findings communicate the significance of sociocultural awareness to informing the teachers’ instruction, as well as their strategies for managing the varying dynamics occurring in their classrooms. It can be deduced from the findings that an understanding of racial inequities is crucial to the development of sociocultural awareness, and is the foundation for the culturally responsive dispositions and practices of these middle school science teachers.  相似文献

In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. Unlike previous studies, we use patent data to examine the evolution of two competing bleaching technologies in five major paper-producing countries, both of which reduce the use of chlorine in the pulping process. The use of patent data allows us to focus on the invention stage. However, adoption data are also presented, and by the end of the 1990s, nearly all pulp production in these countries used one of these technologies. While previous studies emphasize the importance of regulation for inducing innovation, here we find substantial innovation occurring before regulations were in place. Instead, pressure from consumers and the public at large to reduce the chlorine content of paper drove invention, prior to the introduction of environmental policies in any of the countries concerned.  相似文献

Although extant literature suggests that blended, single‐parent, and biological/adoptive (i.e., nuclear) families differ in terms of the boundaries that separate family members, little systematic research has compared such boundaries. The current investigation examined this issue by focusing on communication boundaries as indexed by intrafamily secrets. As expected, college students in blended families reported that their original parents and siblings were more likely than their stepparents or stepsiblings to know the family secret that they reported in this study. This suggests the presence of a relatively rigid communication boundary between original family members and stepfamily members. Interestingly, participants in blended families, single‐parent families, and nuclear families were quite similar in terms of: (a) the number of intrafamily secrets they perceived in their family, (b) the topics of the secrets they reported, and (c) the functions they reported being served by the secrets. Also, regardless of family form, there was an inverse association between participants’ family satisfaction and their perceptions of how many intrafamily secrets their family held. Overall, in contrast to the literature that often portrays blended families and single‐parent families as particularly problematic, these results suggest remarkable similarities across family configurations in terms of communication boundaries.  相似文献

Self-assessment and task-selection skills are crucial in self-regulated learning situations in which students can choose their own tasks. Prior research suggested that training with video modeling examples, in which another person (the model) demonstrates and explains the cyclical process of problem-solving task performance, self-assessment, and task-selection, is effective for improving adolescents’ problem-solving posttest performance after self-regulated learning. In these examples, the models used a specific task-selection algorithm in which perceived mental effort and self-assessed performance scores were combined to determine the complexity and support level of the next task, selected from a task database. In the present study we aimed to replicate prior findings and to investigate whether transfer of task-selection skills would be facilitated even more by a more general, heuristic task-selection training than the task-specific algorithm. Transfer of task-selection skills was assessed by having students select a new task in another domain for a fictitious peer student. Results showed that both heuristic and algorithmic training of self-assessment and task-selection skills improved problem-solving posttest performance after a self-regulated learning phase, as well as transfer of task-selection skills. Heuristic training was not more effective for transfer than algorithmic training. These findings show that example-based self-assessment and task-selection training can be an effective and relatively easy to implement method for improving students’ self-regulated learning outcomes. Importantly, our data suggest that the effect on task-selection skills may transfer beyond the trained tasks, although future research should establish whether this also applies when trained students perform novel tasks themselves.  相似文献

To support pupils’ learning, teachers must understand what and how their pupils have learned, and teacher education should teach candidates how to do this. This article reports on survey data (n = 270) from three programmes and observation data (N = 104 h) from six programmes, located in Norway, Finland and the US. It examines the candidates’ opportunities to analyse pupils’ learning within their coursework. The authors argue that such opportunities might constitute profound possibilities to examine the complexity of teaching and learning. However, the study finds that the candidates have few opportunities to analyse pupils learning and that the full potential of these opportunities is unrealized. The authors argue for increased, specific attention to pupils’ learning within teacher education coursework, through a pedagogy of teacher education informed by existing research on how to elicit pupils’ learning.  相似文献

The strategies children employ to selectively attend to different parts of the face may reflect important developmental changes in facial emotion recognition. Using the Moving Window Technique (MWT), children aged 5–12 years and adults (N = 129) explored faces with a mouse‐controlled window in an emotion recognition task. An age‐related increase in attention to the left eye emerged at age 11–12 years and reached significance in adulthood. This left‐eye bias is consistent with previous eye tracking research and findings of a perceptual bias for the left side of faces. These results suggest that a strategic attentional bias to the left eye begins to emerge at age 11–12 years and is likely established sometime in adolescence.  相似文献

The authors investigated the use of student‐initiated e‐mail as a supplemental modality for supervision. Nineteen students e‐mailed their instructors weekly during their 15‐week practicum; these e‐mails were analyzed across 3 time periods using the categories of the discrimination model (J. M. Bernard, 1979, 1997) and an adaptation of W. Lanning's (1986) professional behavior category. Although patterns of e‐mails were similar across time, there was a significant decline in the number of e‐mails as the practicum progressed. Significance was found for message focus, with personalization messages and professional behavior/practicum class messages accounting for more than half of the messages across 3 time periods.  相似文献

This study used data drawn from a large, national sample to describe transition practices provided to 1989 children with disabilities as they entered their kindergarten year, obtained through a survey administered to kindergarten teachers. Using path modeling, we examined the child and family, school, and district factors that predict which children and families receive high- and low-intensity transition support as they enter kindergarten and, in particular, what types of high-intensity practices they receive. The type of support kindergarten teachers provided was generally comparable to or higher than previously reported data, with low-intensity transition supports more commonly used than high-intensity supports. In a path model that included a range of child and family, classroom, and district factors, four variables emerged as predictors of transition support. Children from larger districts and higher poverty districts who were entering kindergarten from a different setting were less likely to receive support during the transition period. Rural districts differed little overall from suburban districts because they are, on average, higher poverty, but smaller in size. Urban districts demonstrated efforts that counterbalanced the barriers of size and poverty. We include policy implications based on these findings.  相似文献

The purpose of this qualitative study is to understand how educational scaffolding may explain changing patterns of student success in mathematics in the era of developmental education (DE or remediation) reform in Florida College System (FCS) institutions. Specifically, we apply the concept of scaffolding to underprepared FCS students who are at risk of dropping out or failing gateway courses (the first credit-bearing college-level class in a course sequence) because they lack the academic skills necessary to succeed in college-level coursework, particularly in mathematics. We present data from focus groups conducted at 10 FCS institutions, suggesting that a reduction of scaffolding in math remediation occurred in the areas of course sequencing, instruction, and coordination with academic support services following state-level policy changes. In light of these findings, we offer a discussion of practical recommendations for college administrators related to academic advising, instructional strategies in DE courses, coordination between developmental and college-level instructors, student success courses, and the integration of DE instruction with academic support. We also suggest directions for continued research on the effects of policy changes in the FCS and DE reform efforts across the country.  相似文献
