ABSTRACTHistorically, community colleges have played a vital role in career and vocational preparation for students. In today’s complex and ever-changing work environment, professionalism issues are at the forefront of employers’ concerns related to millennials and other young students and recent graduates. This issue is aggravated by the rise of social media and other trends that pose challenges related to, for example, professionalism in communication. The community college community is an excellent site for a movement towards structured professionalism training and research that is process-centered and that emphasizes lifelong learning. Drawn upon the literature review and our own experiences in career counseling, we expand on the perspectives of professionalism at the individual and group levels. And we present on how community colleges’ offices, instructors, and administrators can use the Model of Wisdom Development to understand whether and how are students developing professionalism. 相似文献

We report the Laser Induced Forward Transfer (LIFT) of antibodies from a liquid donor film onto paper receivers for application as point-of-care diagnostic sensors. To minimise the loss of functionality of the active biomolecules during transfer, a dynamic release layer was employed to shield the biomaterial from direct exposure to the pulsed laser source. Cellulose paper was chosen as the ideal receiver because of its inherent bio-compatibility, liquid transport properties, wide availability and low cost, all of which make it an efficient and suitable platform for point-of-care diagnostic sensors. Both enzyme-tagged and untagged IgG antibodies were LIFT-printed and their functionality was confirmed via a colorimetric enzyme-linked immunosorbent assay. Localisation of the printed antibodies was exhibited, which can allow the creation of complex 2-d patterns such as QR codes or letters for use in a final working device. Finally, a calibration curve was determined that related the intensity of the colour obtained to the concentration of active antibodies to enable quantitative assessment of the device performance. The motivation for this work was to implement a laser-based procedure for manufacturing low-cost, point-of-care diagnostic devices on paper. 相似文献

This article explores the contribution of theory to understanding the take-up of information and communications technology (ICT) and, in particular, it describes how Valsiner’s three zones framework came to be used in a study of lecturers in Saudi higher education institutions. The article describes the value of theory and, in the process, illustrates some of the approaches taken in the literature on teachers’ use of ICT. The challenges faced in theorising are also covered. The article then goes on to give the background to a study of ICT use among university lecturers before moving to a discussion of methodology and presentation of key findings. Next, attention shifts to explaining key aspects of Valsiner’s zones framework and showing how this framework was applied to explain the modest but differentiated use of ICT across eight institutions. Finally, the article discusses the strengths and limitations of the zones framework and highlights some of the wider challenges which theorisation poses. 相似文献

Mobile learning (M-learning) is a learning paradigm that utilizes the advantages of mobility and wireless technologies in the learning and education process. It can be characterized by the ability to support and provide strong interaction between learners and instructors, offering high levels of learning motivation, collaboration, and flexibility to the learning activities. Despite the increased popularity of M-learning, there is no complete and well-defined set of educational requirements for M-learning in higher education which considers both instructional design and M-learning design. Therefore, this paper proposes a new educational requirements model for M-learning development and adoption in higher education. This set of requirements has been built from a literature study with focus on standards for learning and mobile application software quality and guidelines. This work presents the results of applying the proposed set of educational requirements on three different M-learning systems. Instructional designers and educational software developers may find the requirements useful in the development of M-learning systems. The effort described is part of an Omani-funded research project investigating the development, adoption and dissemination of M-learning in Oman. 相似文献

The essay represents teaching as the coming to be of the human individual. In order to do so, it reflects on the character of human life by which it is knowledge of itself. Being knowledge of itself, human life is self-determining or free. Therefore generality and particularity come together in the human being in a distinctive way: a human being is not an exemplar, instance or specimen of a species, nature or life-form. Rather, she is her own principle. This is captured in the idea of the human being as an individual. The essay reveals teaching to be the form of coming to be which is proper to what is an individual in this sense. In this way, the essay shows teaching to be internal to human freedom. 相似文献

Despite the crucial role that students play in formative assessment practices, student perspectives on such practices are relatively under-researched. Through a qualitative analysis of 128 reflection notes written by student teachers of English, this article investigates the students’ perceptions of formative feedback as part of portfolio assessment at two teacher education institutions in Norway. As such, it contributes to bridging the gap between research and practice. Students received peer and teacher feedback on assignments and wrote reflection notes during the semester. Findings show that students are positive towards teacher feedback and highlight the significance of teacher praise. Main objections raised against peer feedback concern the lack of constructive criticism. However, positive attitudes towards peer discussion groups suggest that they may be a more effective way of implementing peer assessment than formalised written peer commentary. Student reflections suggest that a failure to understand the task and the feedback is a possible hindrance to successfully revising assignments. Overall, students’ positive attitudes towards the portfolio process, which includes multiple drafting, suggest that students in higher education would benefit from more opportunities to revise and resubmit their work, yet they need adequate practice in providing peer feedback, and interpreting and implementing feedback in general. 相似文献

Our understanding of the writing process can be a powerful tool for teaching language-disabled students the “how” of writing.
Direct, explicit instruction in writing process helps these students learn to explore their ideas and to manage the multiple
demands of writing. A case study of one student, Jeff, demonstrates how we structure the stages of writing: prewriting, planning,
drafting, revising, and proofreading. When these stages are clearly defined and involve specific skills, language-disabled
students can reach beyond their limitations and strengthen their expression. The case study of Jeff reveals the development
of his sense of control and his regard for himself as a writer. 相似文献

Document clustering of scientific texts using citation contexts 总被引：3，自引：0，他引：3
Document clustering has many important applications in the area of data mining and information retrieval. Many existing document
clustering techniques use the “bag-of-words” model to represent the content of a document. However, this representation is
only effective for grouping related documents when these documents share a large proportion of lexically equivalent terms.
In other words, instances of synonymy between related documents are ignored, which can reduce the effectiveness of applications
using a standard full-text document representation. To address this problem, we present a new approach for clustering scientific
documents, based on the utilization of citation contexts. A citation context is essentially the text surrounding the reference
markers used to refer to other scientific works. We hypothesize that citation contexts will provide relevant synonymous and
related vocabulary which will help increase the effectiveness of the bag-of-words representation. In this paper, we investigate
the power of these citation-specific word features, and compare them with the original document’s textual representation in
a document clustering task on two collections of labeled scientific journal papers from two distinct domains: High Energy
Physics and Genomics. We also compare these text-based clustering techniques with a link-based clustering algorithm which
determines the similarity between documents based on the number of co-citations, that is in-links represented by citing documents
and out-links represented by cited documents. Our experimental results indicate that the use of citation contexts, when combined
with the vocabulary in the full-text of the document, is a promising alternative means of capturing critical topics covered
by journal articles. More specifically, this document representation strategy when used by the clustering algorithm investigated
in this paper, outperforms both the full-text clustering approach and the link-based clustering technique on both scientific
journal datasets. 相似文献
