The use of Bluetooth Low Energy (BLE) beacons is becoming widespread for context-aware learning environments. This technology can be used in indoor and outdoor settings such as museums, shops, home and schools in order to identify the location of learners and their contexts. Specifically, in the constructivist view of learning, learners can use such sensing technology for constructing knowledge and experiencing learning at any time, anywhere. However, exploration of such technology has been limited in the constructivist context-aware ubiquitous learning (U-learning) literature. For this purpose, the authors evaluated two android-based U-learning applications: one was an outdoor learning environment in a garden, the other was about locating books in a library. The applications were implemented and tested with school and university students. The qualitative results are presented in this article, and show how such sensing technology is promising for both pedagogical environments.  相似文献   

Pedagogies of Muslim feminisms: reflections on faith,space and citizenship     

Sameena Eidoo 《Gender and education》2018,30(4):513-529

In this article, I offer a qualitative study of three spaces created by and for young Muslim women in Toronto, Canada: an after-school drop-in programme for Muslim girls, a Somali women’s group and a Muslim women’s collective. I focus on data gathered from interviews of seven Muslim women in their 20s who created the spaces, which offered refuge from the racism and Islamophobia in Canadian schools and society and from the patriarchal forms of social control in their families and communities. Drawing on feminist and ethnographic approaches to citizenship studies and a critical faith-centred epistemology, I consider how these spaces function as loci for teaching and learning self and community, building communities of resistance and articulating new notions of the political and of citizenship.  相似文献   

Characterization of lectins and their specificity in carcinomas—An appraisal

Lectins, a group of specific glycoproteins present in animal as well as plant cells, are used as differentiating markers to study cancers and metastatic cell lines. This property of lectins depends on the process of cellular glycosylation. Glycosylation of some of the extracellular membrane proteins and lipids maintains the cell/cell and cell/matrix interactions. Chemical alterations in glycosylation play an important role in the metastatic behavior of tumor cells. Carbohydrate residues of the membrane glycoproteins can be detected using lectins due to their binding specificity to carbohydrates. Lectins, therefore have gained an importance in the field of cancer research. Galectins, a specialized group of lectin like proteins that are Ca+ independent and galactoside binding, are also considered as differentiation markers in some specific cancers like the carcinomas of thyroid. Thus the use of lectins and galectins to identify specific carbohydrates present on cell surface help in invasion and metastasis processes.  相似文献
