We present a practical way of adapting and using four research-based assessments for different purposes in an electricity
and magnetism course for K-8 science teachers. The course is designed to accomplish conceptual change toward accepted scientific
conceptions as well as introducing teachers to materials and activities appropriate for their classrooms. Our data support
that using the research-based tests to identify alternative conceptions and discuss test results with teachers is a promising
way to use the knowledge of alternative conceptions in professional development. We also identify some mismatches between
the research of conceptual change and its use in programs of professional development.

Kohlberg's (1966) hypothesis that the attainment of gender constancy motivates children to attend to gender norms was reevaluated by examining these links in relation to age. Ninety-four 3- to 7-year-old children were interviewed to assess whether and how constancy mediates age-related changes in gender-related beliefs. As expected, results indicated a general pattern of an increase in stereotype knowledge, the importance and positive evaluation of one's own gender category, and rigidity of beliefs between the ages of 3 and 5. Moreover, the stability phase, rather than full constancy, mediated some of these relations. After age 5, rigidity generally decreased with age, with relations primarily mediated by consistency. 相似文献

Evaluating electronic resources: Personal Development Planning resources at the Open University,a case study 总被引:1,自引:1,他引:0
This paper discusses the evaluation of Web‐based tools to support Personal Development Planning (PDP) in order to illustrate issues associated with the introduction and assessment of the effectiveness of online resources. The aims of the evaluation were based on concerns about the very complex situation that offering online resources including PDP poses for part‐time off‐campus students. In this paper the authors utilize a modified RUFDATA framework (Saunders, 2000) and consider the benefits a range of methods, including surveys and observational studies, can offer evaluations of electronic resources. They found that students used and valued some aspects of the provision but that even with best efforts of instructional designers, and user testing at the draft stage, students do not always behave as intended. This evaluation highlighted the need for a range of strategies for evaluating online resources and that regardless of student attitude there are real worries about eLearning imposing extra workload burdens on ‘time poor’ adults. 相似文献

This paper examines the values of the CHE principles of Connectivity, Humanness and Empathy as a guiding framework for maximizing the ethical and methodological advantages of semi-structured interview research practices. The authors draw from two separate educational studies and apply the CHE principles to analyse and evaluate the effectiveness of decision-making in facilitating sustainable relationships with the participants in each study. Findings highlight that dialogical relations with participants were evident in both studies, and identify significant junctures where decision-making and actions influenced effective rapport-building and respectful and reciprocal relationships with participants in the research. The CHE principles emerge as providing a robust framework for educational researchers to employ when auditing their decision-making prior to and during their engagement in qualitative interviews. 相似文献

The World Federation of Scientific Workers (WFScW) and UNESCO share roots in the Social Relations of Science (SRS) movements
and in the Franco-British scientific relations which developed in the 1930s. In this historical context (the Great Depression,
the rise of Fascism and the Nazi use of science, the social and intellectual fascination for the USSR), a new model of scientific
internationalism emerged, where science and politics mixed. Many progressive scientists were involved in the war efforts against
Nazism, and tried to prolong their international commitments into peacetime. They contributed to the establishment of the
WFScW and of UNESCO in 1945–1946. Neither the WFScW nor UNESCO succeeded in achieving their initial aims. Another world emerged
from the immediate post-war years, but it was not the world fancied by the progressive scientists from the mould of scientific
internationalism. The aim of this article is to follow the path from the Franco-British networks towards the establishment
of the WFScW and UNESCO; from an ideological scientific internationalism towards practical projects. It is to understand how
these two bodies came to embody two different scientific internationalisms during the Cold War.

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m2) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship. 相似文献

The international political economy of the hack: A closer look at markets for cybersecurity software
This article examines the development of hacking and cybersecurity software packages as commodities, based on an international political economy of vendors and clients operating in the interstices of international law. Offensive hacking and defensive cybersecurity tools offer new means for surveillance of critics, journalists, and human rights workers, especially in corrupt or authoritarian political systems. The article provides a case study of the Hacking Team, an international “cybersecurity” firm offering spyware and surveillance systems to government security agencies, which was itself hacked and “doxed” in 2015. The leak of documents contributes new knowledge of an international political economy for software products, which exploits the digital rights of targets and which could further undermine general Internet security. 相似文献
