What Do We Really Learn from PISA? The Sociology of its Reception in Three European Countries (2001–2008)1     

Xavier Pons 《European Journal of Education》2011,46(4):540-548

This article synthesises some findings of an international research project called Know&Pol to question the effects of the OECD's Programme for International Student Assessment (PISA) on the public debate in three European countries (France, Portugal and Scotland). Using a political science approach, it shows that Pisa did not favour policy learning among actors, but confirmed their pre-existing opinions and policy stances and that it legitimised them by affixing them with the seal of a statistical international survey.  相似文献   

Multicultural Course Pedagogy: Experiences of Master's‐Level Students of Color          下载免费PDF全文

Derek Xavier Seward 《Counselor Education & Supervision》2014,53(1):62-79

The author conducted a grounded theory study to examine multicultural training as experienced by 20 master's‐level students of color enrolled in multicultural counseling courses. Findings revealed an emergent theory of student of color learning experiences and multicultural course pedagogy. Implications for counselor educators are discussed.  相似文献   

Effects of dynamic resistance training on fascicle length and isometric strength     

Alegre LM  Jiménez F  Gonzalo-Orden JM  Martín-Acero R  Aguado X 《Journal of sports sciences》2006,24(5):501-508

The aims of this study were to assess changes in muscle architecture, isometric and dynamic strength of the leg extensor muscles, resulting from dynamic resistance training, and the relationships between strength and muscle architecture variables. The participants (n = 30) were randomly assigned to one of two groups. The training group (n = 16; age 21.8 +/- 2.3 years, body mass 74.8 +/- 9.2 kg, height 1.75 +/- 0.08 m) performed dynamic resistance training for 13 weeks. The control group (n = 14; age 19.9 +/- 1.5 years, body mass 74.0 +/- 8.5 kg, height 1.76 +/- 0.05 m) did not perform any resistance training. Maximal dynamic and isometric strength were tested in both groups, before and after the training period. The members of the training group used the free-weight squat lift (90 degrees ) as their training exercise. The concentric phase of the squat was performed explosively. Skeletal muscle architecture of the vastus lateralis was visualized using ultrasonography. At the end of the study, significant increases in vastus lateralis muscle thickness (+6.9%, P < 0.001), fascicle length (+10.3%, P < 0.05), one-repetition maximum (+8.2%, P < 0.05), rate of force development (+23.8%, P < 0.05) and average force produced in the first 500 ms (+11.7%, P < 0.05) were seen only in the training group. Adaptations to the muscle architecture in the training group limited the loss of fibre force, and improved the capacity for developing higher velocities of contraction. The architectural changes in the training group were similar to those seen in studies where high-speed training was performed. In conclusion, dynamic resistance training with light loads leads to increases in muscle thickness and fascicle length, which might be related to a more efficient transmission of fibre force to the tendon.  相似文献

Broadband Utilization in Space: Effects of Population and Economic Structure     

Jacint Jordana  Xavier Fernández  David Sancho  Yanina Welp 《The Information Society》2013,29(5):341-351

We examine the effect of public policy on the growth of Internet use. Using a decentralized country—Spain—as an example, we compare the 17 Spanish regions to test different Internet policy designs, taking into account the quality and number of specific programs promoted by regional governments, as well as the presence or absence of strategic planning in each region. We treat the percentage of Internet users as a dependent variable to compare its diffusion in different territories. Our findings show that educational levels and economic differences explain about half of the variations observed. Furthermore, the regional policies play a significant role in explaining regional variations. We investigate which public policy instruments are more significant for the development of the Internet, and find that focused policy intervention and complex policy initiatives are more significant than other policy instruments in explaining the increase in the percentage of Internet users.  相似文献   

Misconceptions About Sound Among Engineering Students     

Arcadi Pejuan  Xavier Bohigas  Xavier Jaén  Cristina Periago 《Journal of Science Education and Technology》2012,21(6):669-685

Our first objective was to detect misconceptions about the microscopic nature of sound among senior university students enrolled in different engineering programmes (from chemistry to telecommunications). We sought to determine how these misconceptions are expressed (qualitative aspect) and, only very secondarily, to gain a general idea of the extent to which they are held (quantitative aspect). Our second objective was to explore other misconceptions about wave aspects of sound. We have also considered the degree of consistency in the model of sound used by each student. Forty students answered a questionnaire including open-ended questions. Based on their free, spontaneous answers, the main results were as follows: a large majority of students answered most of the questions regarding the microscopic model of sound according to the scientifically accepted model; however, only a small number answered consistently. The main model misconception found was the notion that sound is propagated through the travelling of air particles, even in solids. Misconceptions and mental-model inconsistencies tended to depend on the engineering programme in which the student was enrolled. However, students in general were inconsistent also in applying their model of sound to individual sound properties. The main conclusion is that our students have not truly internalised the scientifically accepted model that they have allegedly learnt. This implies a need to design learning activities that take these findings into account in order to be truly efficient.  相似文献
