Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent. 相似文献

In the early 1980s, an influx of child immigrants from Ethiopia forced Youth Aliyah and some of its affiliated youth villages to return, unequivocally, to their initial calling. Yet, reports from the field at that time exuded the sort of spirit expressed by one educator: “The situation in the youth villages that opened their doors wide to the underprivileged is getting worse and worse…. Let's be honest with ourselves: the institutions are attempting to solve today's problems with yesterday's tools (emphasis in the original).1 Research studies at that time, too,2 attested to “disappointing facts” (cf. Adiel's introduction [1980] to a collection of studies). A decade of education, which began when the Jewish Agency entered into a covenant with the Government of Israel and undertook to educate underprivileged Israeli children in Youth Aliyah residential settings, ended in an atmosphere almost bereft of commitment to the original Youth Aliyah mission: providing readily available and suitable frameworks for the accommodation of Jewish youth from any potential source of immigration, however unexpected. 相似文献

UK Orthodox Jewish educators face a number of ethical dilemmas surrounding truth-telling in the classroom. While they must comply with government legislation and high standards of professional conduct, they may also wish their practice to be informed by halachic considerations. This theoretical study explores the potential tensions that may arise when allegiances to the above areas lead to conflicting courses of action, and attempts to plot a course of appropriate conduct that can satisfy all considerations. Direct distortion is identified as an inappropriate tool, whereas omission of content that will hinder students’ Orthodox development is considered preferable to unfiltered disclosure. 相似文献

Microfluidic-based protein arrays are promising tools for life sciences, with increased sensitivity and specificity. One of the drawbacks of this technology is the need to create fresh surface chemistry for protein immobilization at the beginning of each experiment. In this work, we attempted to include the process of surface functionalization as part of the fabrication of the device, which would substitute the time consuming step of surface functionalization at the beginning of each protein array experiment. To this end, we employed a novel surface modification using self-assembled monolayers (SAMs) to immobilize biomolecules within the channels of a polydimethylsiloxane (PDMS) integrated microfluidic device. As a model, we present a general method for depositing siloxane-anchored SAMs, with 1-undecyl-thioacetate-trichlorosilane (C11TA) on the silica surfaces. The process involved developing PDMS-compatible conditions for both SAM deposition and functional group activation. We successfully demonstrated the ability to produce, within an integrated microfluidic channel, a C11TA monolayer with a covalently conjugated antibody. The antibody could then bind its antigen with a high signal to background ratio. We further demonstrated that the antibody was still active after storage of the device for a week. Integration of the surface chemistry into the device as part of its fabrication process has potential to significantly simplify and shorten many experimental procedures involving microfluidic–based protein arrays. In turn, this will allow for broader dissemination of this important technology. 相似文献

This paper traces the mainstreaming of American Jewish history and social studies in the American Jewish school curricula, a process which began in the 1920s and picked up momentum in the mid‐late 1930s and 1940s. From the beginning, the raison d'etre for teaching American Jewish history and community studies was articulated in terms of socialization as opposed to content. Thus, the extent to which an educational agency or institution's agenda was driven by a desire to effect students’ social adjustment as opposed to expanding their knowledge base, and the degree to which the educational program itself was shaped by indigenous as opposed to Eastern European Jewish pedagogic paradigms and priorities determined their receptivity to American Jewish history and social studies as legitimate fields of study. 相似文献
