Higher education and K-12 school partnerships are typically designed with an end-goal that serves the instructional needs of one group over the other. For this project, a university professor and elementary school instructor used problem-based and project-based learning strategies to design a curriculum that served the academic needs of both groups of students. Undergraduate students in an urban planning course partnered with elementary students from a local school to work on an interdependent civic engagement project. The partnership provided innovative, twenty-first teaching for both groups of students while also reinforcing public service. 相似文献

What happens when a team of university education researchers initiates a social justice learning project in a local high school, and – despite the overall project’s considerable successes in cultivating students’ critical political ‘voice’ – is confounded by the periodic, apparent ‘silences’ of some of its young female students? Drawing on eight years of fieldwork in a groundbreaking high school social justice education classroom, this article examines the presumptions inherent in certain forms of social justice pedagogy, and the ways in which ensuing classroom disjunctures may, in fact, lead to deeper insights about education for youth critical social consciousness. The article focuses on two, interrelated issues: the unsettling and sometimes confounding ‘silences’ of female students and the correlation between such silences and social justice educators’ attenuated ability to recognize and support the myriad ways in which minority female students may encounter, negotiate, and articulate their own particular forms of Freirian conscientización. 相似文献

Research on student veterans is in an infant state. As veterans continue to enroll in institutions of higher education, researchers must explore new ways of knowing student veterans. It is not enough to only describe and model this growing demographic, researchers must also have a tool for criticism and question. The next in an important tradition of emancipatory paradigms, this article suggests a critical theory built on current critical conversations but adapted for the unique characteristics of the student veteran. The article defines the need for a critical theory (Veteran Critical Theory), explains 11 tenets for this new theory, and discusses how these tenets could be used by administrators, faculty, student affairs professionals, and students in the higher education community. 相似文献

This study focuses on high school students’ profile choices and the choice for or against the Nature and Technology (NT) profile in the Netherlands. A mixed-methods approach is used to study cultural values that affect this choice. The quantitative part of the study shows that being female is negatively correlated with the choice for the NT-profile, irrespective of the grade average for mathematics, chemistry and physics. It further shows that students’ ethnic background does not have a significant effect on this choice. The qualitative part of the study reveals that students’ choice processes towards or away from NT can be categorised in three ideal types: the postmodern perfectionist, the pragmatic hedonist and the materialist maximalist. Gender differences appear to be more pervasive across these types than differences in ethnic background. 相似文献

The Nobel Prize in Chemistry for the year 2016 was awarded to three illustrious chemists, Professors Jean-Pierre Sauvage, Sir Fraser Stoddart, and Ben Feringa. Pioneering works of these chemists on designing molecules, chemically synthesizing them, and extracting a work out of such designed molecules open-up a new area of chemistry in a paradigm shifting manner. Beginning with controlling the molecular motions, particularly involving interlocked macrocycles in late 1980s, the advancement progressed to envelop energy storage and retrieval, and varieties of examples around the concept. Molecular motion alone can also be a rich source for such a work output has also been established. These developments possess the required momentum to uncover a new area of chemistry, wherein energy input-output can be used beneficially to conduct a useful work, in a close analogy to machines such as an electric motor. 相似文献

The brachistochrone problem posed by Bernoulli and its solution highlights one of the most famous experiments in physics which illustrates the variational principle. This pedagogical study is designed to ignite a classroom discussion on the variational problem. We overview the Euler–Lagrange formalism of the variational principle and obtain the solution to the brachistochrone problem. We demonstrate the success of the variational method using brachistochrone models which were fabricated specially for this purpose. 相似文献

Greeks used the method of cutting a geometric region into pieces and recombining them cleverly to obtain areas of figures like parallelograms. In such problems, the boundary is ignored. However, in our discussion, we will take every point of space into consideration. The human endeavour to compute lengths, areas, and volumes of irregular complicated shapes and solids created the subject of ‘measure theory’. The paradox of the title can be informally described as follows. Consider the earth including the inside stuff. It is possible to decompose this solid sphere into finitely many pieces and apply three-dimensional rotations to these pieces such that the transformed pieces can be put together to form two solid earths! The whole magic lies in the word ‘pieces’. The pieces turn out to be so strange that they cannot be ‘measured’. 相似文献

This phenomenological study explored six single mothers’ experiences of support at their young children’s school. Themes resulting from interpretative phenomenological analysis suggest the single mothers experienced tangible (e.g., school resources, school-wide events, structural flexibility, teachers’ formal communication) and intangible (e.g., caring relationships with school faculty and staff, experiencing teachers as parenting partners, perceiving acceptance from the school environment) forms of support from their children’s school. Furthermore, results suggest these single mothers experienced intangible supports more prominently than tangible forms of support. The support needs of these single mothers at their young children’s school were also explored including the mothers’ desire for stronger relationships with other parents and families at the school. 相似文献

The purpose of this qualitative study was to examine teachers’ attitudes and experiences with coaching. This study was conducted in advance of a planned randomized controlled trial of a coaching intervention to better align the model with teachers’ needs and goals. Thirty-four K–5 general (n = 26), special education (n = 6), and educational support staff (n = 2) working in two high-poverty schools participated in focus groups. Interrater reliability between independent coders was high (К = 0.92; range: 0.76–1.0). Thematic analyses identified facilitators and barriers to teacher participation in the planned intervention and were used to improve upon the existing coaching model. Themes focused on advantages and disadvantages to coaching and characteristics of effective coaches and coaching models. Implications of findings for research and practice are discussed. 相似文献

As we progress in the 21st century, children learn to become proficient readers and writers of both digital and non-digital texts. Knowledge, skills, and understandings of literacy emerge through sociocultural interactions with non-digital tools (e.g., paper-printed books) and digital tools (e.g., touch screen tablets). However, debate is ongoing over the role that digital experiences play in emergent literacy development. Researchers have voiced the need to conceptualise a common framework for literacy development that considers the emergence of digital literacy skills alongside conventional literacy skills and how these skills might interact during development. This is particularly important in light of the increasing use of digital texts used by young children, such as E-books and digital games. Therefore, this paper proposes a framework that might guide research and practice by examining the relationships between emergent literacy skills, emergent digital literacy skills, and proficiency in reading and writing. 相似文献
