In contemporary African societies where multiple systems of knowledge coexist, and the use of informatics is becoming increasingly widespread, conventional perspectives drawn from cultural anthropology, environmentalism, development studies and intellectual property rights are insufficient guides to thinking about the digitization of indigenous knowledge. Taking an interdisciplinary approach, three moments in South African knowledge dynamics are used to probe some of the ontological, epistemological, and performative implications of science/IKS interaction in the design and construction of archives and databases of local plants. Twenty-first century databases of indigenous African medico-botanical knowledge need to assure that it is recontextualized historically and socially; that its multiplicity, visuality, and orality are retained; and that “articulation work” is done to make sure that design choices and use are cognitively just. 相似文献

Research has revealed a significant gap between the thinking patterns and software design habits of students or recent computer science university graduates and those of expert software developers.There may be several causes for this gap, one of which is undoubtedly the fact that throughout their studies students are mostly asked to write software programs of relatively lim-ited scope, and are not usually required to work as part of a team constructing a complex program.In the present paper we will describe a study unit intended to be taught as part of a high school computer science curriculum, which emphasizes the software system aspects. In a study that accompanied the development and actual teaching of the unit, we checked, among other things, whether the students acquired skills for developing a complex software system. 相似文献

Recently, learning technologies have become a pivotal constituent of teaching–learning processes. Contemporary studies indicate that in order to effectively utilize these technologies, instructors and learners alike must master a range of cognitive and socio-emotional competencies, commonly termed “digital literacy competencies” or “21st century skills.” This study employs a content analysis methodology to trace trends of change in the research of core digital literacy competencies as reflected in the educational academic literature of the past 37 years (1980–2016). Based on well-established frameworks of digital literacy competencies, this research examined seven skills: Collaboration, Communication, Creativity, Critical thinking, Information literacy, Problem-solving and Socio-emotional skills. Data were collected through advanced search queries of peer-reviewed publications in the Education Resources Information Center (ERIC) database. Findings reveal that among the examined terms, Communication is the most prominent digital literacy skill, followed by Problem Solving and Collaboration. Furthermore, within the context of Skills, the most prominent terms are Information Literacy and Critical thinking; Technology and Collaboration are least mentioned. Our findings suggest that awareness of digital learning competencies in educational research literature is marginal, implying that educational research seems to lag behind the need to understand the ever-changing digital competencies that instructors and learners need. 相似文献
