Despite widespread support for integrated approaches to teaching, classroom practice reveals a lack of implementation. This paper explores challenges and opportunities in teaching an integrated curriculum, and connects this with the contemporary notion of a twenty-first century curriculum and pedagogy. A case study of Global Education (GE) is used to delineate the complexity of issues when teachers attempt to move beyond disciplinary-based teaching approaches. We examine curriculum documents, advice for teachers on curriculum implementation, preservice teachers’ experiences in schools during Professional Experiences and national guidelines for Professional Experience. Through these data, a broad picture emerges of influences on integrating curricula in classrooms. Opportunities to integrate curriculum incorporating twenty-first century pedagogies were limited by pressures on teachers with preservice teachers rarely exposed to authentic integration. Teachers’ professional standing requires clear guidelines, which allow them to pursue important twenty-first century content and skills , for young citizens and this must begin in preservice education.  相似文献

正我们热爱艺术!艺术是只有人类可以创造且欣赏的罕见形式之一。然而,艺术行业却是一个相对封闭的行业,面临着诸多的挑战。例如:1.新兴艺术家很难打人市场;2.艺术品的评价与交易缺乏透明度,这阻碍了新的市场参与者进入;3.人们一般认为单个买家负担不起艺术作品的花费,事实也的确如此;4.艺术作品的出处和交易记录缺少透明度,因此,如果想"了解内幕",则这种活动进一步限制了市场活动。Kbean是一种技术解决方案,可以通过区块链  相似文献

There are three reasons why probability samples often become separated from their putative populations in mass communication research. First, researchers sometimes believe populations must surely exist when in fact they do not exist. Yet they relentlessly pursue these phantom populations rather than heed classic warning signs that something is wrong. Second, researchers often struggle with underpowered samples. Rather than render those samples using more appropriate qualitative methods, they plow ahead using misapplied statistical methods and thus never inferentially connect to a population. Third, researchers frequently and incorrectly use random assignment rather than random selection as a sample method. This, in turn, can leave a sample unconnected to a population if the population can be drawn only through random selection. As obvious as these three errors are, researchers nonetheless stumble into them regularly. We examine why that is and what researchers can do to avoid these errors.  相似文献

A content analysis of rap music videos aired on BET, MTV, and VH1 examined the occurrence of controversial themes, gender differences, and skin tone distortion. The results of this study found that current rap music videos have placed an emphasis on themes of materialism and misogyny. Additionally, men and women in the videos differ in their portrayal of these themes. Specifically, female characters are significantly more likely to appear as objects of sexuality. Men and women also differ in their appearance with more African American females appearing to have Eurocentric features. Implications and suggestions for future research are discussed.  相似文献

Academic journals have traditionally provided disciplinary forums for scholarly communication (i.e., vetting, legitimating, and disseminating new ideas). Digitization is affecting scholarly communication and academic journals. Two effects are the bundling of journals by publishers and the growing variety of formats that open up new avenues of dissemination. Both effects have disrupted the traditional roles and relationships of scholars and their institutions, publishers and libraries in the processes of scholarly communication, including the significance of academic journals as a format.  相似文献

This study explores the library instructional programming and resources of high school library media centers in western Montana with the intent of documenting and understanding both the services provided to and the experiences of first-year college students at the University of Montana. Results from the survey (n = 22) and site visits (n = 10) reveal wide variation in the levels and types of library instructional programming provided at the library media centers, including media specialists’ perceptions of high school students’ information literacy skills. However, consistency was seen in the media specialists’ collection management strategies and in collection content. The results suggest implications for first-year library programming and highlight opportunities for further 9–16 collaboration and study.  相似文献

The Gutenberg‐e project was created as an experiment to explore whether peer‐reviewed, born‐digital monographs would alter the way in which historical scholarship is presented, whether scholars would receive the same professional credit for these publications as for work published in print, and whether the project would enable publication of monographs that would otherwise be turned down by university presses for financial reasons. The project reached the following conclusions: authors and publishing staff collaborated in creating new models of scholarship and writing; over the course of the project, attitudes toward digital publications evolved toward acceptance of this new form of publication; the time and costs involved in creating these models exceeded expectations; continued experimentation is necessary in order to keep up with authors' growing expectations in publishing digital scholarship.  相似文献

In this study,particle image velocimetry was applied to investigate flow fields of wormlike micelle(WLM) fluids in a mixing tank equipped with a four-blade,down-pumping,pitched blade turbine. First,the rheology of WLM fluids was investigated,and the Carreau model was utilized to describe their apparent viscosity. Then,the effects of the rotation speeds and rheological properties on the flow fields were studied using different WLM fluids at different rotation speeds. The results revealed that with increasing Reynolds number,the discharge angle decreases and the carven size increases. Furthermore,elastic effects of WLM fluids lead to a more curved flow and a smaller carven.  相似文献

Strength training with isometric contractions produces large but highly angle-specific adaptations. To contrast the contractile mode of isometric versus dynamic training, but diminish the strong angle specificity effect, we compared the strength gains produced by isometric training at four joint angles with conventional dynamic training. Thirty-three recreationally active healthy males aged 18?–?30 years completed 9 weeks of strength training of the quadriceps muscle group three times per week. An intra-individual design was adopted: one leg performed purely isometric training at each of four joint angles (isometrically trained leg); the other leg performed conventional dynamic training, lifting and lowering (dynamically trained leg). Both legs trained at similar relative loads for the same duration. The quadriceps strength of each leg was measured isometrically (at four angles) and isokinetically (at three velocities) pre and post training. After 9 weeks of training, the increase in isokinetic strength was similar in both legs (pooled data from three velocities: dynamically trained leg, 10.7%; isometrically trained leg, 10.5%). Isometric strength increases were significantly greater for the isometrically trained leg (pooled data from four angles: dynamically trained leg, 13.1%; isometrically trained leg, 18.0%). This may have been due to the greater absolute torque involved with isometric training or a residual angle specificity effect despite the isometric training being divided over four angles.  相似文献
