This article draws on data from a qualitative research study undertaken in an old UK university. The main aim of the study was to measure the impact of gender issues on the university campus, an important part of which was the issue of the curriculum. Individuals were found to operate either a 'narrow' or 'broad' definition of the term 'curriculum'. In either case, there was found to be a 'gender dimension' involved. In male-dominated disciplines a 'narrow' definition of the term 'curriculum' was predominantly in use-appropriate discipline content and an unproblematic body of knowledge, which is to be transferred to students largely by lecturing. The difficulties to be overcome in order to undertake a gender-sensitive evaluation of the curriculum in these departments stemmed from the evaluations of the staff of what the problem was and where it was located. In disciplines that accepted a broader definition, which included the 'informal' curriculum, the gendered division of labour in the domestic sphere was repeated in the university, with the result that the division 'rational/emotional' became an aspect of the masculine/feminine divide. Men as well as women felt that men were less inclined to undertake the emotion work involved in supporting student learning. In this male-dominated society, 'emotion work' such as the pastoral support of students remained virtually invisible, and went largely unrewarded.  相似文献

Researchers of after-school tutoring primarily focus on educational outcomes with little attention to the social dynamics of such programs. In our qualitative case study, we examined the nature of interactions among tutors in a tutoring program at a homeless shelter for families. Employing Bourdieu’s concepts of social capital and field, we found that the dynamics between tutors were complex, with tutors jockeying for position amid contestations over the rules and organization of the tutoring sessions. The implications include the significant impact that the dynamics among tutors can have on the overall program.  相似文献

Previous research has found that embedding a problem into a familiar context does not necessarily confer an advantage over a novel context in the acquisition of new knowledge about a complex, dynamic system. In fact, it has been shown that a semantically familiar context can be detrimental to knowledge acquisition. This has been described as the “semantic effect” (Beckmann, Learning and complex problem solving, Bonn, Holos, 1994). The aim of this study was to test two competing explanations that might account for the semantic effect: goal adoption versus assumptions. Participants were asked to learn about the causal structure of a linear system presented on a computer containing three outputs by changing three inputs through goal free exploration. Across four conditions the level of familiarity was experimentally varied through the use of different variable labels. There was no evidence that goal adoption can account for poor knowledge acquisition under familiar conditions. Rather, it appears that a semantically familiar problem context invites a high number of a priori assumptions regarding the interdependency of system variables. These assumptions tend not to be systematically tested during the knowledge acquisition phase. The lack of systematicity in testing a priori assumptions is the main barrier to the acquisition of new knowledge. The semantic effect is in fact an effect of untested presumptions. Implications for research in problem solving, knowledge acquisition and the design of computer-based learning environments are discussed.  相似文献

Abstract

As technology has spread in schools, we know little about how technology mediates the performance of primary-aged students and their engagement in mathematics. Given the well-established link between achievement and engagement, understanding the impact of technology on engagement can inform practice. This study examines how technology might impact second graders’ engagement in mathematics using IXL, a math intervention administered on the iPad, as compared to a traditional paper–pencil approach. Although there was not a statistically significant difference in the pre–post student engagement surveys, the teacher focus group described increased student independence using technology and found it easier to differentiate and provide corrective feedback, while helping students build fluency.  相似文献

This article examines the ethos of the hacktivist movement Anonymous. It considers the subcultural roots of Anonymous and the political and ethical values articulated by the movement. The article highlights key points of tension within the Anonymous ethos: nihilism and idealism, utopianism and dystopianism, individualism and collectivism, and negative and positive liberty. The article argues that while Anonymous can be broadly understood as cyberlibertarian, it is more complex and contradictory than this singular label implies. However, it also argues that the Anonymous ethos is not so amorphous that it prevents ideological analysis and critique. The article concludes by discussing the wider political significance of Anonymous when seen in this light.  相似文献

Social media can be used to assess public opinions and emotions during different stages of a crisis. Guided by the Crisis and Emergency Risk Communication (CERC) model, this study examined a systematic sample of 2,881 tweets from a corpus of over one million tweets posted during the initial, maintenance, and resolution stages of the 2015 California measles outbreak. It found that the public showed the greatest interest (as measured by the number of tweets and retweets) in the initial stage of the crisis, but their interest drastically declined afterward. The expression of humor/sarcasm was significantly more frequent in the initial stage than in the maintenance or resolutions stage, while the expression of reassurance increased significantly from the initial, maintenance, and resolution stage. The emotion of alarm/concern was most frequently expressed during the initial stage. For message types, the public were more likely to tweet about their personal opinions and less likely to tweet about resources during the initial stage. These findings allow public health professionals to better design messages in response to the public’s concerns and emotions during public health crises.  相似文献
