The scientometric world of Keith Pavitt: A tribute to his contributions to research policy and patent analysis     

Martin Meyer  Tiago Santos Pereira  Ove Granstrand 《Research Policy》2004,33(9):1405-1417

Keith Pavitt has made pioneering contributions to the study of science, technology and innovation. This paper aims to examine some of them on the basis of a bibliometric analysis of Keith Pavitt's work and the impact that he has had. First the paper follows how Pavitt's publication profile develops over time. Then we trace his most cited works and explore the sets of references in his papers. Author and journal co-citation maps illustrate the intellectual environment associated with Pavitt and the central role Research Policy played in this context. An analysis of the most frequently cited authors in Research Policy and Scientometrics underlines Keith Pavitt's role as both a shaper of, and a bridge between, science and technology policy and bibliometric analysis.  相似文献   

Guided portfolio writing as a scaffold for reflective learning in in-service contexts: a case study1     

Íris Susana Pires Pereira  Maria Cristina Cristo Parente  Cristina Vieira da Silva 《Teacher Development》2016,20(5):614-630

Language is widely recognized as an inescapable mediating tool for professional learning, and with this text we want to contribute to a better understanding of the particular role that guided writing can play in in-service professional reflective learning. We analysed one pre-school teacher’s written portfolio, the construction of which was guided to scaffold deep thinking about (and the transference of theory into) practice during participation in an in-service program about language education. Our case study shows that the writing process sustained robust learning about professional knowing, doing and learning itself: The teacher elaborated an integrative ethical understanding of the discussed theory, fully experienced newly informed practices and assessed her own learning by using theory to confront her previous knowledge and practices. Throughout the portfolio, the learning stance revealed by her voice varied accordingly. The study illustrates the potential of guided writing to scaffold reflective learning in in-service contexts.  相似文献   

Using Portfolios for External Assessment: An Experiment in Portugal     

Maria Teresa Torres Pereira de Ea 《The International Journal of Art & Design Education》2005,24(2):209-218

This article describes some of the conclusions reached from an experiment using portfolios for art external assessment at the end of secondary education (age 17+) conducted in five Portuguese schools in 2001–2003. Several positive outcomes were found. Students found portfolios to be motivating and fostering constructive learning, dialogue and co‐operation between students and teachers. The new assessment procedures developed communities of assessors enabling some increased consistency of examination results and positive professional development opportunities. However some weaknesses were detected such as potential bias related to the degree of teacher aid and practical problems as, for example, time‐consuming in‐service teacher training.  相似文献

EFFECTIVENESS OF THE FRIENDS FOR LIFE PROGRAM IN PORTUGUESE SCHOOLS: STUDY WITH A SAMPLE OF HIGHLY ANXIOUS CHILDREN     

Ana Isabel Pereira  Teresa Marques  Vanessa Russo  Luísa Barros  P. Barrett 《Psychology in the schools》2014,51(6):647-657

The FRIENDS for Life program is a cognitive–behavioral group program that targets anxiety in children. The main purpose of this study was to analyze the effectiveness of the Portuguese version of the FRIENDS for Life Program, which was implemented in schools to reduce anxiety problems in a group of highly anxious children. The study used a quasi‐experimental research design with two groups of children, an intervention (n = 17) and a wait‐list control group (n = 21), aged 8 to 12 years old. The impact of the program in reducing anxiety symptoms as assessed by children and mothers was analyzed through the Screen for Child Anxiety Related Emotional Disorders‐Revised (SCARED‐R). The results show a statistically significant post intervention effect on anxiety symptoms evaluated by the child, but not by the mother. The implications of these results for the prevention of anxiety disorders in Portuguese schools are discussed.  相似文献   

Differentiation as measured by the Classroom Practices Survey: a validity study updating the original instrument     

Pereira  Nielsen  Tay  Juliana  Maeda  Yukiko  Gentry  Marcia 《Learning Environments Research》2019,22(3):443-460

The Classroom Practices Survey assesses educators’ use of differentiated instruction with students achieving at average and high levels. The purposes of this study were to investigate if the Classroom Practices Survey (1) yields reliable and valid data from the groups for which it was originally designed and (2) can be used to evaluate teachers’ differentiation practices for students who achieve at low levels. Participants included 648 elementary teachers who completed the Classroom Practices Survey for students achieving at high, average and low levels. Confirmatory factor analyses revealed that the original six-factor model was not supported by the current data. Model fit was improved with a four-factor model, but did not reach the recommended values for good model fit. Further research and possibly modifications are needed before this tool is used by researchers and schools. This study highlights the importance of periodically evaluating instruments and revising them if necessary.

Assessment of integration method for displacement determination using field accelerometer and geophone data     

F. Lamas-Lopez  Y. J. Cui  S. Costa D’Aguiar  N. Calon 《浙江大学学报(A卷英文版)》2017,18(7):553-566

A conventional French railway track was instrumented with accelerometers and geophones at three depths: sleeper (surface), interlayer (ITL, z=?0.93 m), and transition layer (TL, z=?1.20 m). A linear variable differential transformer (LVDT) was also used to monitor the displacement at the sleeper level. The recorded data allow the integration method (double for accelerometer and simple for geophone) for displacement determination to be assessed. Several questions need to be addressed prior to the selection of an adequate monitoring system: definition of signal filtering processes, influence on results of the different loading wavelengths, repeatability of measurements, train speed and axle load impact and their ranges of validity for each sensor. It was found that the main frequencies that caused more than 95% of the displacement of the monitored materials are in the low frequency range: <25 Hz for trains running up to 200 km/h. For an intercity train, the low frequencies are normally excited by long wavelengths, for instance, those corresponding to the 1/2 coach distance (λ=13.20 m), the bogies distance (λ=6.3 m), and the axle distance (λ=2.8 m). Comparison between the displacements deduced from the records of accelerometer and geophone and obtained from the records of LVDT shows quite consistent results; the mean displacement amplitudes obtained from accelerometers differ by only 20% from the LVDT records. The train speed does not have a strong effect on the obtained differences between sensors. The embedded sensors also gave consistent displacement results for each analysed depth. Moreover, the displacement amplitudes caused by different axle loads (locomotive or passenger coach) are distinguishable for all sensors at all depths. This validates the integration method used for the displacement determination.  相似文献   

The Influence of Toy Design Activities on Middle School Students’ Understanding of the Engineering Design Processes     

Ninger Zhou  Nielsen L. Pereira  Tarun Thomas George  Jeffrey Alperovich  Joran Booth  Senthil Chandrasegaran  Jeffrey David Tew  Devadatta M. Kulkarni  Karthik Ramani 《Journal of Science Education and Technology》2017,26(5):481-493

The societal demand for inspiring and engaging science, technology, engineering, and mathematics (STEM) students and preparing our workforce for the emerging creative economy has necessitated developing students’ self-efficacy and understanding of engineering design processes from as early as elementary school levels. Hands-on engineering design activities have shown the potential to promote middle school students’ self-efficacy and understanding of engineering design processes. However, traditional classrooms often lack hands-on engineering design experiences, leaving students unprepared to solve real-world design problems. In this study, we introduce the framework of a toy design workshop and investigate the influence of the workshop activities on students’ understanding of and self-efficacy beliefs in engineering design. Using a mixed method approach, we conducted quantitative analyses to show changes in students’ engineering design self-efficacy and qualitative analyses to identify students’ understanding of the engineering design processes. Findings show that among the 24 participants, there is a significant increase in students’ self-efficacy beliefs after attending the workshop. We also identified major themes such as design goals and prototyping in students’ understanding of engineering design processes. This research provides insights into the key elements of middle school students’ engineering design learning and the benefits of engaging middle school students in hands-on toy design workshops.  相似文献   

Learning as the Construction and Re-mediation of Activity Systems: Environmental Management in Biogas Production     

Marco A. Pereira Querol  Timo Suutari  Laura Seppänen 《The Journal of Agricultural Education and Extension》2013,19(4):373-384

Abstract

The purpose of this paper is to present theoretical tools for understanding the dynamics of change and learning during the emergence and development of environmental management activities. The methodology consists of a historical analysis of a case of biogas production that took place in the Southwest region of Finland. The theoretical tools used helped to see how the content of an activity guided the historical emergence and change of an EM activity. The practical implication of the paper is that environmental solutions should not be restricted to the adaptation of a system, but should also include the possibility of constructing a new activity, with a new object and means of production. The paper is original in presenting theoretical tools for grasping the content of learning in environmental management activities.  相似文献
