This study further extends a conceptual framework that explores science teaching as a “practice” not reducible to the application of formal knowledge, but as informed by teachers' practical‐moral knowledge. A hermeneutic model was developed to examine practical‐moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions between them. The study also aimed to analyze teachers' actions in terms of their interpretations and commitments as they realize “internal goods” of their practice. Ethnographic case studies of three science teachers were conducted through classroom observation, in‐depth interviews and dialogues, and artifact analysis. A commitment of preparing students for national exams was common to the three teachers but was manifested differently in classroom practices. This commitment originated from interpretations about the duty of “good” teachers not letting students and schools down. Other emergent commitments were commitments: to conceptual understandings, to “challenge” learners, and to social modeling. We present each with associated interpretations and actions. The concepts of practical wisdom (phronesis) and gap closing are used to characterize teachers' practical knowledge and its development respectively. Implications for teacher education are discussed. © 2010 Wiley Periodicals, Inc. J Res Sci Teach 47: 929–951, 2010 相似文献

The current study examined within‐family relations between mothers’, fathers’, and children's objectively assessed sleep. Participants were 163 children (Mage = 10.45 years; SD = 0.62) and their parents. For 7 nights, families wore actigraphs to assess sleep duration (minutes), quality (efficiency, long wake episode, total wake minutes), and schedule (wake time). A sleep log assessed bedtime. Multilevel models indicated that children's sleep minutes, sleep efficiency, wake minutes, and wake time were associated with fluctuations in their mothers’, but not fathers’, sleep that same night. The duration and quality of mothers’ sleep was associated with both fathers’ and children's sleep that night, whereas fathers’ sleep was positively associated with only mothers’ sleep. Findings highlight the importance of examining sleep within a family context. 相似文献

This most helpful book supports action learning practitioners in organising collaborative working and knowledge generation and implementation. The case studies help inspire and motivate readers to take action, and the book as a whole leans towards practical guidance rather than being loaded with theory. It's a readable text for aspiring action learning practitioners aiming to drive forward and implement such ideas, and to share learning at system‐wide scale. It also serves as a quick reference guide for the personal libraries of more seasoned practitioners and other leaders and developers. If the content of this book is likely to be relevant to you, I recommend that you buy a copy for your own use. Nancy El‐Farargy 相似文献

Abstract How are new media, such as electronic mail, voice mail, and fax, used when people have access to several of them simultaneously? This paper reports findings from a field study of media use in four sizable subunits within two large organizations where most employees had access to email, vmail, and fax. Respondents tended to use multiple electronic media rather than relying on one. However, they also showed a tendency to prefer one medium for asynchronous communication and to use the others for occasional, specialized purposes. Further, there were considerable differences across subunits in typical media use patterns. Although respondents expressed strong desires for multimedia integration, this study suggests that technological integration may not necessarily result in seamless, collaborative work. 相似文献

ABSTRACT. This study investigates how mathematics secondary schools' teachers in \hbox{Jordan} perceive critical thinking and compares teachers' perceptions before and after educational reform. Data were collected from 12 schools twice: in 1988 and in 2004 by interviewing 47 Mathematics teachers. The interview included questions related to teachers' understanding of critical thinking, its role and importance in learning Mathematics, and instructional strategies that could help improve students' critical thinking skills. Results found no improvement in secondary Mathematics teachers' perceptions of critical thinking despite 15 years of educational reform. The majority of Mathematics teachers seemed not to have a clear and adequate understanding of critical thinking. Though most of the teachers claimed they have to teach critical thinking, more than half of them could not suggest any learning situation that could help in fostering critical thinking in Mathematics classes. Also most of the teachers claimed that critical thinking would help students in learning Mathematics; yet less than half were able to give a convincing justification for that. A small percentage of the secondary Mathematics teachers believed they can help all students to foster their critical thinking. It is thus recommended that the concept of critical thinking be transferred from the realm of rhetoric to the field of practice. The paper ends with some recommendations related to the Mathematics teachers training programs in view of the results of this study. 相似文献

Frequency dependent dynamic properties from resonant column and cyclic triaxial tests 总被引:1,自引:0,他引:1
The resonant column (RC) and cyclic triaxial (CT) devices are commonly used for the measurement of soils’ dynamic properties. The results of these tests do not agree when extrapolated to similar strain levels. The main objectives of this paper are to evaluate the effect of excitation frequency on the dynamic properties of soils, and to provide a methodology to reconcile shear modulus values obtained from RC and CT tests. The effect of frequency on the dynamic properties is evaluated using the new non-resonance (NR) method in the RC device and CT tests. Sand specimens with varying percentages of bentonite-water mixture and a clay specimen are tested. The results obtained from RC tests utilizing the NR method indicate significant change in shear modulus with frequency. The extrapolation of shear modulus from the conventional RC results to shear strains used in CT is significantly overestimated. The extrapolations improved when the results were corrected for frequency effect inferred from the NR method. 相似文献
