Noticing and weighing alternatives in the reflection of regular classroom teaching: Evidence of expertise using mobile eye-tracking     

Keller  Lena  Cortina  Kai S.  Müller  Katharina  Miller  Kevin F. 《Instructional Science》2022,50(2):251-272

Instructional videos are widely used to study teachers’ professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers’ professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video feedback to examine how expert and novice teachers differed in their noticing and weighing of alternative teaching strategies. Expert and novice teachers’ lessons were recorded with MET devices. Then, they commented on what they observe while watching their own teaching videos. Using a mixed methods approach, we found that expert and novice teachers did not differ in the number of classroom events they noticed and alternative teaching strategies they mentioned. However, novice teachers were more critical of their own teaching than expert teachers, particularly when they considered alternative teaching strategies. Practical implications for the field of teacher education are discussed.

In search of systemic innovation for sustainable development: A design praxis emerging from a decade of social learning inquiry

Processes of designing for systemic innovation for sustainable development (SD) through the lens of three long-term case studies are reported. All case studies, which originated from the SLIM (Social Learning for the Integrated Management and Sustainable Use of Water at Catchment Scale) Project, funded within the EU Fifth Framework Program (2001–2004), constitute inquiry pathways that are explored using a critical incident approach. The initial starting conditions for each inquiry pathway are compared; significant pathway dependencies are identified which foster the development of social learning processes locally, but constrain their uptake and embedding across the wider system of interest. In the first case study, in England & Wales, promising developments in the application of social learning approaches to river basin planning over an initial 3-year period were subsequently marginalised, only to resurface towards the end of the 10-year period of study. In the second, South African case study, significant spaces for social learning and innovation in integrated water resources management were opened up over a five year period but closed down again, primarily as the result of lack of policy support by national government. The third, Italian, case study was designed to assess options for adapting to climate change by opening up new learning spaces between researchers, stakeholders and policy makers. A case for investing in local level systemic innovation through social-learning praxis design approaches and in learning processes around well contextualised case-studies is supported. However, concomitant investment by policy makers in social learning as an alternative, but complementary, governance mechanism for systemic innovation for SD is needed.  相似文献   

When do firms rely on their knowledge spillover recipients for guidance in exploring unfamiliar knowledge?     

Hongyan Yang  H. Kevin Steensma 《Research Policy》2014

Knowledge spillover occurs when recipient firms combine the knowledge of an originating firm with other knowledge. When recipient firms combine the originating firm's knowledge with knowledge that is unfamiliar to the originating firm, the recipient firms potentially provide insight to the originating firm on the viability of exploring such knowledge. By mimicking its recipient firms, the originating firm reduces the challenge and uncertainty of exploring unfamiliar knowledge domains. We examine the exploration activities of 87 telecommunications equipment manufacturers over a ten-year time period. We argue that those firms that operate in competitive and dynamic market environments promoting conservative risk-taking behavior will value such uncertainty reduction more highly and thus rely to a greater extent on their recipient firms for guidance on where to explore for new expertise. In contrast, firms in high-growth market environments are more likely to look beyond the activities of recipient firms when exploring new technological domains and rely less on mimicking their recipient firms.  相似文献   

Tilted post arrays for separating long DNA     

Joel D. P. Thomas  Kevin D. Dorfman 《Biomicrofluidics》2014,8(3)

Recent simulations by Chen and Dorfman [Electrophoresis 35, 405–411 (2014)] suggested that “tilting” the electric field with respect to the lattice vectors of a hexagonal post array would lead to a substantial improvement in electrophoretic DNA separations therein. We constructed such an array where the electric field is applied at an angle equidistant between the two lattice vectors. This tilted array leads to (i) baseline resolution of 20 kbp DNA and λ DNA (48.5 kbp) in a 4 mm channel and (ii) measurable separation resolutions for electric fields up to 50 V/cm, both of which are improvements over untilted post arrays of the same post density. The predicted time required to reach a resolution of unity is approximately 5 min, independent of electric field. The separations are more reproducible at higher fields.  相似文献   

‘Active Citizens’: the case of school governors     

Kevin J. Brehony 《International Studies in Sociology of Education》2013,23(2):199-217

ABSTRACT

This article reviews current and historical debates about active, participant citizens and related conceptions of citizenship. In particular it focusses on the prospects for the participation of citizens in the administration of public bodies. It discusses critically the notion of participative citizenship and active citizenship as articulated by Douglas Hurd (when Home Secretary) and also the version contained in the report of the Speaker's Commission on Citizenship. The article then draws upon research conducted for the Volunteer Centre, by the National Foundation for Educational Research and that by Brehony and Deem which is funded by an Economic and Social Research Council Grant (R000 23 1799), on voluntary activity and school governors, respectively. The applicability of the concept of active citizenship to the oversight of schools by school governing bodies is then considered alongside recent work in the United States. The article then considers the constraints upon active citizenship which prevent many governors from participating as much as the role demands and it ends with a reference to the tension between those who see governing bodies as an arena for democratic accountability and the active participation of citizens and those who view them principally as a means by which the local state is weakened and its functions increasingly transferred to the voluntary sector.  相似文献   

Teacher Acceptability of Functional Assessment-Derived Treatments     

Kevin M. Jones  Cheryl J. Lungaro 《Journal of educational and psychological consultation》2013,23(3-4):323-332

This study examines whether teachers find a treatment clearly linked to a functional assessment more acceptable than treatments based on arbitrarily selected reinforcers. We randomly assigned 111 elementary school teachers to 3 experimental conditions. In all conditions, a problem vignette was read that included the same functional assessment summary but varied according to whether the treatment recommendation was linked to the assessment results. A one-way analysis of variance revealed significantly higher pretreatment acceptability ratings and likelihood of use for the treatment linked to assessment. Implications of these results for school-based consultation are discussed.  相似文献   

Intellectual self-mutilation     

Kevin Robins  Frank Webster 《Higher Education Quarterly》1985,39(2):97-104

[The] business man is generous to a fault, but one thing he does demand of all teachers and lecturers and journalists: if we're going to pay them our good money, they‘ve got to help us by selling efficiency and whooping it up for rational prosperity? And when it comes to these blab-mouth, fault-finding, pessimistic, cynical University teachers, let me tell you that during this golden coming year it's just as much our duty to bring influence to have these cusses fired as it is to sell all the real estate and gather in all the good shekels we can.
