Drawing on the concept of transformative expectations—that is, the instructional practices that demonstrate teachers’ belief systems for the educational justice and empowerment of Chicanx/Latinx youth—this qualitative study explored the expectancy effects of nine classroom teachers with social justice commitments in a school district in California. Through semi-structured interviews, teacher journaling, and artifacts of classroom practices, this study points to the importance of teacher disposition and socialization in developing classroom expectations, as well as helps to conceptualize the expectancies of academic rigor, social capital, empowering curriculum, and teacher caring from perspectives of justice and their importance in supporting students to meet or exceed instructional goals. Applying figured worlds and transformative expectations as the study’s analytic frameworks, teachers reported these four expectancies as important strategies for bringing social justice into the classroom, thereby prompting discussions of the future directions of teaching for social justice. 相似文献

A microfluidic rectifier incorporating an obstructed microchannel and a PDMS membrane is proposed. During forward flow, the membrane deflects in the upward direction; thereby allowing the fluid to pass over the obstacle. Conversely, during reverse flow, the membrane seals against the obstacle, thereby closing the channel and preventing flow. It is shown that the proposed device can operate over a wide pressure range by increasing or decreasing the membrane thickness as required. A microfluidic pump is realized by integrating the rectifier with a simple stepper motor mechanism. The experimental results show that the pump can achieve a vertical left height of more than 2 m. Moreover, it is shown that a maximum flow rate of 6.3 ml/min can be obtained given a membrane thickness of 200 μm and a motor velocity of 80 rpm. In other words, the proposed microfluidic rectifier not only provides an effective means of preventing reverse flow but also permits the realization of a highly efficient microfluidic pump. 相似文献

Background: In Bangladesh, a common science curriculum caters for all students at the junior secondary level. Since this curriculum is for all students, its aims are both to build a strong foundation in science while still providing students with the opportunities to use science in everyday life – an aim consistent with the notion of scientific literacy.Purpose: This paper reports Bangladeshi science teachers’ perspectives and practices in regard to the promotion of scientific literacy.Sample: Six science teachers representing a range of geographical locations, school types with different class sizes, lengths of teaching experience and educational qualifications.Design and method: This study employed a case study approach. The six teachers and their associated science classes (including students) were considered as six cases. Data were gathered through observing the teachers’ science lessons, interviewing them twice – once before and once after the lesson observation, and interviewing their students in focus groups.Results: This study reveals that participating teachers held a range of perspectives on scientific literacy, including some naïve perspectives. In addition, their perspectives were often not seen to be realised in the classroom as for teachers the emphasis of learning science was more traditional in nature. Many of their teaching practices promoted a culture of academic science that resulted in students’ difficulty in finding connections between the science they study in school and their everyday lives. This research also identified the tension which teachers encountered between their religious values and science values while they were teaching science in a culture with a religious tradition.Conclusions: The professional development practice for science teachers in Bangladesh with its emphasis on developing science content knowledge may limit the scope for promoting the concepts of scientific literacy. Opportunities for developing pedagogic knowledge is also limited and consequently impacts on teachers’ ability to develop the concepts of scientific literacy and learn how to teach for its promotion. 相似文献

Abstract Several lines of evidence suggest that dehydroepiandrosterone sulphate (DHEA-S) is invariably consumed following different types of acute stress, implicating its role in stress coping and recovery. The role of DHEA-S in the mood adjustment against negative outcome for athletic competition has not previously been investigated. In the current study, 14 elite golfers participating in a major national golf tournament were subsequently divided into two groups according to their competition outcomes: made the cut (n = 8) and failed to make the cut (n = 8). The Profile of Mood States (POMS) inventory and plasma concentrations of DHEA-S and cortisol were measured 1 day before the beginning of competition (baseline) and 1, 3, and 5 days after the players' final competition, in the morning (08.00–08.30 h) under fasted conditions. Results showed that the total mood disturbance scores and DHEA-S were not changed for the group that made the cut throughout the entire observation period. DHEA-S concentration for the group that failed to make the cut fell significantly below baseline values on day 1 and remained lower for 5 days. The Depression subscale of the POMS for the group that failed to make the cut was increased only on day 1 post-competition, reflecting a situational reaction to the event. Cortisol concentration for the group that made the cut fell significantly below baseline values on day 1 only after competition and no change was observed for the group that failed to make the cut. In conclusion, although the overall mood state post-competition was well-maintained for those golfers who had a negative competition outcome, plasma DHEA-S concentration was reduced for 5 days, suggesting that it has a role in the coping mechanism against psychological challenge. 相似文献

The Common Core State Standards (CCSS) potentially shifts the way US schools approach teaching and learning. Research suggests that it is important to understand how educators view the CCSS and how they believe the CCSS may impact their practice. We developed and tested an instrument to investigate educator beliefs about the implementation of CCSS. We collected data from two samples of educators regarding their beliefs about the CCSS in mid-size school districts in California that had begun to introduce the CCSS. Our results indicate that the instrument consistently measured three interrelated, yet distinct, sub-constructs of educator beliefs about the CCSS implementation and that the sub-constructs are statistically significantly associated with trust, professional knowledge, and the pattern of CCSS-related professional interaction. 相似文献
