Scientists played a key role in the first systematic introduction of nature study into North American public schools in the late nineteenth century. The initiatives of Wilbur Jackman and John Merle Coulter, affiliated with the young University of Chicago, and Liberty Hyde Bailey and Anna Botsford Comstock, at Cornell University, coincided with the "new education" reform movement that found object lessons and experience-based education superior to textbook teaching. Educational psychologists and philosophers of the 1890s, including G. Stanley Hall, related curriculum methods to perceived developmental stages in children, with a focus on immediate experience. Putting these pedagogical ideas--gained in summer institutes, normal schools, and programs at Chicago and Cornell--into practice were administrators and classroom teachers in both urban and rural classrooms. By 1900, a consensus about the value of nature study among scientists, community leaders, and teachers established it as the recognized general method of studying the natural world in public schools across much of the United States. 相似文献

This paper presents findings from a three-year, qualitative study of teachers enrolled in a Masters of Teacher Leadership program. Researchers sought to understand the ways teachers’ beliefs about and understandings of teacher leadership were affected by their participation in a formal teacher leadership program, as well as the kinds of actions they took up as a result of this participation. Data indicate three significant ways participants’ work as teacher leaders was developed and enhanced, including: (a) identifying and amplifying their professional voice, (b) deepening and extending their voice as they plan, and (c) reframing their work/shift responsibility through constructing widening circles of influence and impact. Authors identify implications of their research for growing teacher leaders, school improvement and change, changing school culture, enhancing student engagement, and building new structures. 相似文献

Although progress has been made, greater efforts are needed to promote faculty diversity at the college and university levels,
especially in STEM fields. Thus, it is important to elucidate best practices both for increasing awareness of diversity issues
pertaining to higher education and for implementing change. This article focuses on the outcomes of a diversity workshop for
college and university faculty hosted by the West Virginia Higher Education Policy Commission, Division of Science and Research.
More specifically, it elucidates how participation in the workshop translated into practice at the faculty participants’ home
institutions. 相似文献

This article begins with Pollock’s comment that Judith Butler ‘finds hope in failure’ and its aim is to explore what ‘hope in failure’ means in relation to A Level students’ engagements with post-feminism and feminism. The article grounds its argument in an exploration of how post-feminism and feminism intersect with sixth form students’ subjectivities through the educational practices of their second-year A Level subject-based research. The article analyses empirical instances of students’ discursive agency through Butler’s notions of performativity, citationality, excessive signification and resignification to consider the complex, multiple and creative ways in which sixth form students produce themselves as viable gendered subjects in relation to post-feminist and feminist discourses. The analysis considers both how discourse regulates and conditions students’ relations with post-feminism and feminism and how discourse contains the possibilities for the subject to refuse the refusal of feminism in popular culture. Through its analysis of how students use their discursive agency to claim a feminist identity, and how these uses constitute transgressive practices, the article explores the political significance of identifications with feminism in doing gender differently. It ends with an argument for the re-consideration of the apparently assured popular cultural ‘failure’ of feminism in post-feminist neoliberal times. 相似文献

Gregory Lewis Bynum 《Educational theory》2011,61(1):17-40
Immanuel Kant envisioned a kind of respect in which one recognizes each human (1) as being not fully comprehensible by any human understanding, (2) as being an end in him‐ or herself, and (3) as being a potential source of moral law. In this essay, Gregory Lewis Bynum uses this conception of respect as a lens with which to examine African American education rights on three levels: the individual level (the level of individual persons' moral experience and moral significance), the community level (the level of the formation and sustaining of social groups that have value for humanity), and the global level (the level of a universal community of humanity). Bynum's goal in this examination is to strengthen our practical understanding of African Americans' right to education defined, in accordance with international human rights documents, as the right to an education that supports the full development of the human personality in a manner that respects students' “cultural identity, language, and values.” 相似文献

This paper focuses on the perspectives of Years 7 and 8 Pasifika students on mathematics learning, in particular their views about the communication of solution strategies with others (their peers), and their teacher. Pasifika students' ideas about the importance of communicating their mathematical reasoning and strategies to peers and teachers were analysed and themes identified. While most students were in agreement about the importance of explaining their thinking to others, there was considerable variation in the reasons they gave for their views. The findings are interpreted in relation to socio-cultural theory and recent writing about requirements for citizenship in the twenty-first century. 相似文献

The design and fabrication of a membrane-integrated microfluidic cell culture device (five layers,≤500 μm total thickness) developed for high resolution microscopy is reported here. The multi-layer device was constructed to enable membrane separated cell culture for tissue mimetic in vitro model applications and pharmacodynamic evaluation studies. The microdevice was developed via a unique combination of low profile fluidic interconnect design, substrate transfer methodology, and wet silane bonding. To demonstrate the unique high resolution imaging capability of this device, we used oil immersion microscopy to image stained nuclei and mitochondria in primary hepatocytes adhered to the incorporated membrane 相似文献

Repeated-sprint training often involves short sprints separated by inadequate recovery intervals. The effects of interval duration on metabolic and performance parameters are unclear. We compared the effects of two training programmes, differing in rest interval duration, on muscle (vastus lateralis) metabolism and sprint performance. Sixteen men trained three times a week for 8 weeks, each training session comprising 2-3 sets of two 80-m sprints. Sprints were separated by 10 s (n = 8) or 1 min (n = 8). Both training programmes improved performance in the 100-, 200-, and 300-m sprints, but the improvement was greater in the 10-s group during the final 100 m of the 200- and 300-m runs. Independent of interval duration, training mitigated the drop of muscle ATP after two 80-m sprints. The drop in phosphocreatine and the increases in glucose-6-phosphate and fructose-6-phosphate after two 80-m sprints were greater in the 10-s group. In conclusion, training with a limited number of repeated short sprints (≤10 s) may be more effective in improving speed maintenance in 200- and 300-m runs when performed with a 1:1 rather than a 1:6 exercise-to-rest ratio. This may be due to a greater activation of glycolysis caused, in part, by the limited resynthesis of phosphocreatine during the very short rest interval. 相似文献

The purpose of this study was to determine the validity of the metabolic equivalent (MET) equation and step rate function of the ActivPAL? physical activity logger in a group of females. Using a standard treadmill protocol, 62 females aged 15-25 years walked on a treadmill at speeds between 3.2 and 7.0 km · h(-1) while wearing an ActivPAL. Oxygen consumption was measured using expired gas analysis at each speed and METs for each speed were estimated based on each participant's own resting metabolic rate. A sub-set of 18 participants also wore an Actigraph. Results showed that the in-built equation in the ActivPAL significantly underestimated (P < 0.001) METs under treadmill conditions at higher intensities. The ActivPAL equation is based on step rate yet the relationship between counts and measured METs (r = 0.76; P < 0.001) is stronger than that between steps and measured METs (r = 0.59; P < 0.001). Both the ActivPAL and Actigraph step functions showed no significant difference (P > 0.05) to video recorded step rate except at the slowest walking speed where the Actigraph significantly underestimated steps (P < 0.05). The development of a new equation based on the counts-METs relationship that includes a variety of speeds and activities would be useful. The ActivPAL step function performs better than the Actigraph at the slowest walking speed under treadmill conditions. 相似文献
