This study examines Swedish upper secondary school teachers’ gendered conceptions about students’ mathematical reasoning: whether reasoning was considered gendered and, if so, which type of reasoning was attributed to girls and boys. The sample consisted of 62 teachers from six different schools from four different locations in Sweden. The results showed that boys were significantly more often attributed to memorised reasoning and delimiting algorithmic reasoning. Girls were connected to gamiliar algorithmic reasoning, a reasoning type where you use standard method when solving a mathematical task. Creative mathematical founded reasoning, which is novel, plausible and founded in mathematical properties, was not considered gendered.

In this study, an electro-mechanical valve （EMV） system for the intake valve ofa fottr stroke, single cylinder, overhead valve and spark ignition （SI） engine was designed and constructed. An engine with the EMV system and a standard engine were tested to observe the effects of the EMV on engine performance and emissions at different speeds under full load. The EMV engine showed improved engine power, engine torque and break specific fuel consumption （BSFC）. A 66% decrease in CO emissions was also obtained with the EMV system, but hydrocarbons （HC） and NOx emissions increased by 12% and 13% respectively. 相似文献

We examine practice theories concerned with knowledge sharing in complex organizations to distinguish common trends and variations in this complex body of work. We suggest that an analytical framework highlighting the relational thinking in practice theories can serve as a tool to sort through the literature on knowledge sharing. First, we delineate a relational framework consisting of seven attributes associated with a practice theory. Second, we use this framework to analyze a narrow set of practice theories represented by three seminal works on communities of practice. Third, we compare and contrast the relational dynamics found in the three seminal works in regard to how they conceptualize knowledge sharing within and across communal boundaries. 相似文献

AbstractTaking its point of departure in the idea that language is never neutral but always coded in the masculine or the feminine (Irigaray), the main purpose of the paper is to explore the gendered coding of Religious Education teaching and how this coding interplays in shaping relationships and knowledge in the classroom. As recent research shows, debates about religion are becoming increasingly aggressive in many Western democracies and Religious Education is not unaffected by this. Drawing on Luce Irigaray’s notion of sexual difference the paper argues that RE tends to have a masculine coding in its overemphasis on beliefs, creeds and concepts. This not only positions both girls and boys as feminine in relation to (masculine) religion, it also fails to offer the more nuanced understanding of religious life so well needed today. The paper is divided into three sections. The first outlines briefly, theoretically and methodologically, the larger study of which this paper is part. The second offers an exposition of Irigaray’s thinking on sexual difference, and the third relates her philosophy to three empirical examples. The paper ends with a summary of the main points of the argument and the implications of language matters for Religious Education teaching. 相似文献

In this article we report on findings from a large-scale bibliographic study conducted based on the citation practices within the field of research on adult learning. Our data consist of 151,261 citation links between more than 33,000 different authors whose papers were published in five leading international journals in the field of adult learning during the time period 2006–2014. By analysing the composition of the dominating citation clusters we are able to construct a telescopic view of the research field based on an accumulation of bibliographic citations. The results consist of two parts. First we go through the dominating players active in the field, their position and mutual relationship. Secondly, we derive two main structural oppositions inherent in the citation networks, one connected to the research object (studying education or work) and the second to the level of analysis (cognition or policy). We find that the most dominating tradition within adult learning the last few decades – sociocultural perspectives on learning - occupies a very central position in the space of citations, balancing between these opposing poles. We hope that this analysis will help foster reflexivity concerning our own research practices, and will reveal the relations of dominance currently prevailing within the field of adult learning. 相似文献

Upper secondary students’ task solving reasoning was analysed with a focus on arguments for strategy choices and conclusions. Passages in their arguments for reasoning that indicated the students’ beliefs were identified and, by using a thematic analysis, categorized. The results stress three themes of beliefs used as arguments for central decisions: safety, expectations and motivation. Arguments such as ‘I don’t trust my own reasoning’, ‘mathematical tasks should be solved in a specific way’ and ‘using this specific algorithm is the only way for me to solve this problem’ exemplify these three themes. These themes of beliefs seem to interplay with each other, for instance in students’ strategy choices when solving mathematical tasks. 相似文献

Although growing numbers of secondary school mathematics teachers and students use calculators to study graphs, they mainly
rely on paper-and-pencil when manipulating algebraic symbols. However, the Computer Algebra Systems (CAS) on computers or
handheld calculators create new possibilities for teaching and learning algebraic manipulation. This study investigated the
views of Turkish prospective secondary mathematics teachers on the use of advanced calculators with CAS in algebra instruction.
An open-ended questionnaire and group interviews revealed prospective teachers’ views and beliefs about when and why they
prefer three possible uses of CAS—black box, white box, or Symbolic Math Guide (SMG). The results showed that participants
mainly preferred the white box methods and especially SMG to the black box method. They suggested that while the black box
method could be used after students mastered the skills, the general white box method and SMG could be used to teach symbolic
manipulation. 相似文献

Newcomers often underestimate the challenges of interdisciplinary work and, as a rule, do not spend sufficient time to allow them to overcome differences and create common ground, which in turn leads to frustration, unresolved conflicts, and, in the worst case scenario, discontinued work. The key to successful collaboration is to facilitate the creation of a climate that will stimulate awareness of such challenges. Differing perceptions of quality and credibility among disciplines are major obstacles to successful collaboration. Some of these differences are incommensurably rooted in different epistemologies while other differences are more a question of culture. In the present paper, a framework is proposed which is designed to initiate a process necessary for success. First, the framework is designed to stimulate discussions about quality and credibility, and second it is designed to help separate epistemological differences from differences in culture. The framework takes its point of departure in five questions that deliberately include terms, such as ‘sufficiently’, ‘coherently’, and ‘reliable’, which are unproblematic in a group with shared norms but become increasingly ambiguous as diversity increases. Experience suggest that pondering these questions, alone or in a group, stimulates reflection, leads to increased awareness of one’s own perspective, and facilitates dialogue, collaboration, and creation of common ground. 相似文献

The aim of this study is to explore feedback practices and how such actions of assessment emerge from embodied participation in classroom interactions between teachers and students. Using video recordings of teacher and student interactions in hairdressing education, I look at how feedback practices within creative subject content are produced between the participants as social actions situated in interaction, using conversation analysis. Feedback is contingent upon an embodied moment-to-moment monitoring and collaboration between the teacher and student, and is organized as a trajectory from problem detection through exploration until a final solution is found. Feedback within creative subject content is displayed as a multifarious exploration of embodied as well as materially situated professional knowledge. Overall, the findings show how feedback is mutually produced in a process, making tacit dimensions of hairdressers’ knowing explicit. This allows for improving the quality of the work over time in a trajectory of problem solving phases gradually displaying how to assess creative subject content of the material product worked on. 相似文献
