Imagine the challenge of being immersed in a dynamic learning network where you play brinkmanship with being overwhelmed by a plethora of information, comments, and conversations on a topic of intense interest to you. Through adept facilitation, the comments and encouragement of fellow participants, and your own perseverance, you develop a network of personal connections which serve as metaphorical flying buttresses creating enough stability that you are able to learn in a new, yet profoundly meaningful way – the connectivist massive open online course (cMOOC) way. Through the lens of autoethnography, five seasoned educators collaboratively reflect on their motivation for participating in their initial cMOOC. They analyze their lived experience, what they found most engaging, and most importantly, they grapple with why cMOOC communities often endure past official end-dates. This article attempts to provide insight into the thrill and depth of learning and connection possible through participation in cMOOCs. 相似文献

In this paper we introduce the concept of a Prolog programming technique. This concept is then distinguished both from that of an algorithm and that of a programming cliché. We give examples and show how a knowledge of them can be useful in both programming environments and in teaching programming skills. The extraction of the various techniques is outlined. Finally, we discuss the problem of representing techniques where we conclude that the most promising approach is the development of a suitable meta-language. 相似文献

This article discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. It begins with a discussion of the difference between practising science and learning to practice science. It follows with a discussion and refutation of three commonly held motives for using practicals in science education. It concludes with the presentation of three new, better motives for their use. 相似文献

This case study illustrates instruction in an urban 6th‐grade classroom in which students were learning about mass, volume, and density by attempting to layer (stack) three miscible solutions with differing densities atop one another. The study examines classroom discourse and interaction on the basis of four teaching goals: (a) reaching consensus about which stacks were possible, (b) developing persuasive arguments that separated data from noise, (c) establishing social norms for collective inquiry, and (d) appreciating the epistemological status of scientific knowledge. The study traces the fate of three stacks that students claimed were possible after initial investigations with the solutions. These claims underwent a process of collective validation in which consensus without coercion was the goal, which illustrates emergent standards for backing claims with evidence, as well as for replicability, among the students. Students were successful in achieving three of the four goals, with some qualifications. In relation to Goal 3, which required generalization to other situations, somewhat less success is reported. Limitations in the current standards, difficulties of time allotment in current curricula, and establishing classroom cultures of inquiry are discussed. © 1999 John Wiley & Sons, Inc.

This study determined if test rats could utilize biological odors, generated from donor rats receiving reward (R) and frustrative nonreward (N) treatments, to predict reward and nonreward goal events equally well. In Phase 1, two groups of test rats were exposed to R and N odors that signaled, respectively, either R and N goal events (“same” condition) or N and R goal events (“opposite” condition). Rats demonstrated significant discriminative use of these odors under both conditions. Subjects in the “opposite” condition, however, were slightly slower to learn the discrimination. Reversal learning was readily accomplished in Phase 2, regardless of the same-opposite factor. Thus, little evidence for a constraint on learning was found, and an interpretation in terms of interfering response tendencies and their habituation seemed favored. 相似文献

Genetics instruction in introductory biology is often confined to Mendelian genetics and avoids the complexities of variation in quantitative traits. Given the driving question “What determines variation in phenotype (Pv)? (Pv=Genotypic variation Gv + environmental variation Ev),” we developed a 4-wk unit for an inquiry-based laboratory course focused on the inheritance and expression of a quantitative trait in varying environments. We utilized Brassica rapa Fast Plants as a model organism to study variation in the phenotype anthocyanin pigment intensity. As an initial curriculum assessment, we used free word association to examine students’ cognitive structures before and after the unit and explanations in students’ final research posters with particular focus on variation (Pv = Gv + Ev). Comparison of pre- and postunit word frequency revealed a shift in words and a pattern of co-occurring concepts indicative of change in cognitive structure, with particular focus on “variation” as a proposed threshold concept and primary goal for students’ explanations. Given review of 53 posters, we found ∼50% of students capable of intermediate to high-level explanations combining both Gv and Ev influence on expression of anthocyanin intensity (Pv). While far from “plug and play,” this conceptually rich, inquiry-based unit holds promise for effective integration of quantitative and Mendelian genetics. 相似文献

While recognising the fact that historically teacher education and adolescent literacy are two fields that have had limited intellectual contact, the development of reading literacy is increasingly now accepted internationally as a core responsibility of all teachers and teacher educators. Adopting a socio-cultural perspective, this paper, drawn from the Learning to Teach Study, focused on the beliefs, knowledge and experiences regarding reading literacy of Irish post-primary student teachers on one initial teacher education (ITE) programme. The data were collected through three interviews with each of 17 student teachers. Results suggest that the surveyed student teachers had some concerns about their own literacy, had narrow conceptions of literacy, tended not to see it as their responsibility, held a minimal threshold view of literacy and viewed new digital technologies as a resource and motivator for their students’ literacy learning. Results are discussed in terms of how student teachers’ knowledge of literacy in ITE programmes could be reframed, extended and deepened. 相似文献

This paper reports on the second phase of a joint teacher/researcher project that explored teachers’ understandings of the potential of the interactive whiteboard (IWB) as a tool for primary school children’s collaborative group work. By examining teachers’ written analyses and discussions of work carried out in their own classrooms, the paper seeks to contribute to the debate about the ways in which the use of IWBs can contribute to changes in pedagogy. It highlights the interrelationships between collaborative learning and factors identified as important in the research carried out by teachers, amongst them the children’s technical skills and confidence, the mediating role of the teacher, the IWB affordances for knowledge‐building and the teachers’ own knowledge, attitudes and professional development. The paper also provides an account of how participation by the teachers in a course with Faculty staff, focused on the collaborative co‐construction of knowledge related to learning and to classroom research grounded in the values and principles of socio‐cultural theory, supported changes in pedagogic practice. 相似文献
