Moving PISA Results into the Policy Arena: Perspectives on Knowledge Transfer for Future Considerations and Preparations     

Larry D. Yore  John O. Anderson  Mei-Hung Chiu 《International Journal of Science and Mathematics Education》2010,8(3):593-609

Evidence-based policies, decisions, and practices are highly valued and underachieved in the international mathematics and science education reforms. Many in the mathematics and science education research communities lament the lack of influence that research results have on the education profession, schools, and teaching. Academic research done in isolation of end-users—with the faint hope that teachers, politicians, and bureaucrats will access and utilise these results to inform curriculum, assessment, and instruction and to influence public policy—has not worked. Some funding agencies require dissemination of research and development results to the broader political and education communities; therefore, applicants agree to these requirements without fully realizing the breadth of these demands. However, to achieve such knowledge transfer requirements, researchers need to become more (a) aware of the needs, players, and processes of ‘speaking truth to power’; (b) active in knowledge transfer and influencing public policy; and (c) alert to values and normative premises of the policy makers. This article outlines the essential principles, barriers within the academic community, international efforts, and future considerations for knowledge transfer regarding international assessments. Specific articles on PISA 2000, 2003, and 2006 included in this special issue are used to illustrate these insights into verification of curricular influences, educational opportunity and equality, regional comparisons, and direct influence on policy.  相似文献   

FIRST CYCLE OF PISA (2000–2006)—INTERNATIONAL PERSPECTIVES ON SUCCESSES AND CHALLENGES: RESEARCH AND POLICY DIRECTIONS     

John O. Anderson  Mei-Hung Chiu  Larry D. Yore 《International Journal of Science and Mathematics Education》2010,8(3):373-388

This special edition of IJMSE focuses on the Programme of International Student Assessment (PISA) project now that it has completed a full cycle of administration—reading, mathematics, and science—to look at ways in which PISA has been used in participating countries and with what consequences, and to identify potential research and policy directions emanating from this initiative. Articles were invited to (a) reflect international perspectives on the uses and consequences of PISA to date and (b) speculate on future directions for research, curriculum, and policy using the PISA datasets. The introductory article provides a brief overview of common aspects of PISA: Evolving definitions of reading literacy, mathematics literacy, and science literacy; technical design of the instruments and data analysis procedures; the changing emphasis of administrations; and recent research using the datasets. PISA, unlike other international assessments in reading, mathematics, and science, has provided a fresh perspective on ‘what might be’ by decoupling the assessment from mandated curricula to focus on literacies needed for a 21st century economy. This unique feature of PISA brings with it possibilities and cautions for policy makers.  相似文献   

Should I Stay or Should I Go? Examining the Career Choices of Alternatively Licensed Teachers in Urban Schools   总被引：1，自引：0，他引：1  

Jennifer C. Ng  Lizette Peter 《The Urban Review》2010,42(2):123-142

In order to address the issue of persistent teacher shortages, urban districts increasingly rely on alternatively licensed teachers who are often viewed as well-suited to work in urban areas because of their greater age, life and work experiences, and understanding of diverse communities. Yet, research on the retention of these teachers remains inconclusive, with some notable studies suggesting that alternatively licensed teachers are as likely as their traditionally prepared counterparts to quit teaching or migrate out of urban school settings. In this study, we explore the process and salient considerations of five alternatively licensed math and science teachers deciding whether or not to continue teaching in a Midwestern, urban school district. Whereas previous studies typically examine teacher recruitment and retention issues through a narrow analysis of labor market incentives and other external inducements, our study situates teachers’ career decisions within a more holistic narrative that illustrates how individual actions are never determined by any single factor, but rather a web of simultaneous and sometimes contradictory forces generated by prior expectations and immediate realities that are professional as well as personal in nature.  相似文献   

A comparison of the agreement,internal consistency,and 2-day test stability of the InBody 720, GE iDXA,and BOD POD® gold standard for assessing body composition     

Bruce W Bailey  Gabrielle LeCheminant  Timothy Hope  Mathew Bell  Larry A Tucker 《Measurement in physical education and exercise science》2018,22(3):231-238

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for all three machines (27.6 ± 10.0% [GE iDXA)] 25.6 ± 10.4% [BOD POD], and 21.3 ± 10.6% [InBody 720]; p < .05). The coefficient of variation for same day repeated measures was 1.06% (GE iDXA), 3.29% (BOD POD), and 2.97% (InBody 720). The coefficient of variation for 2-day repeated measures was 1.81% (GE iDXA), 4.61% (BOD POD), and 4.24% (InBody 720). The difference between the GE iDXA and BOD POD was within acceptable variability, while the InBody 720 significantly underestimated % BF. The internal consistency was highest for the GE iDXA, followed by the InBody 720, and then the BOD POD.  相似文献   

Visualization of Wormlike Micelle Fluid Flow in a Mixing Tank     

Hongyuan Wei  Jieliang Lu  Chong Gu  Kate Xu  Boonho Ng  Leping Dang 《天津大学学报(英文版)》2018,(4)

In this study,particle image velocimetry was applied to investigate flow fields of wormlike micelle(WLM) fluids in a mixing tank equipped with a four-blade,down-pumping,pitched blade turbine. First,the rheology of WLM fluids was investigated,and the Carreau model was utilized to describe their apparent viscosity. Then,the effects of the rotation speeds and rheological properties on the flow fields were studied using different WLM fluids at different rotation speeds. The results revealed that with increasing Reynolds number,the discharge angle decreases and the carven size increases. Furthermore,elastic effects of WLM fluids lead to a more curved flow and a smaller carven.  相似文献

Effectiveness of Rest,Abdominal Cold Packs,and Cold Showers in Relieving Fatigue     

Elmo S. Roundy  Larry Don Cooney 《Research quarterly for exercise and sport》2013,84(3):690-695

Abstract

The purpose of this study was to compare three methods of relieving fatigue between bouts of strenuous exercise—rest, abdominal cold packs, and cold showers. Fifteen subjects were used in the study; each subject participated in each of the three treatments, making a total of 45 measurements. The subjects ran on a treadmill which was set at 8 mph with a 10 percent elevation, until their pulse rates reached 180 beats per minute. One of the three treatments was then applied for 10 min., after which the subjects engaged in a second treadmill run until heart rates reached 180 beats per minute. The time of the second treadmill run was the main criterion measure.

A complete randomized block design was used to test the differences among the three treatments for statistical significance. The Newman-Keuls sequential range test was employed to test differences between all possible pairs of treatment. Abdominal cold packs proved to be the most effective treatment, with the cold shower second and rest third.  相似文献

Abstract

Nineteen college men and women (aged 18–23 yrs, × = 21.1) were studied to ascertain the force-time components of a rapid maximal voluntary isometric contraction (MVC) for ankle dorsiflexors, knee extensors, elbow flexors, wrist flexors and hand grip. Standardized isometric strength testing protocol was used. After a practice period subjects were instructed to make an MVC without jerking and as quickly as possible, for each of the muscle actions noted above. Force readings were taken from a load cell assembly through an analogue-to-digital converter and analyzed to yield time values for MVC, 3/4 MVC, 1/2 MVC, and 1/4 MVC. The results indicated significant differences (p < .01) between the responses of the men and women, with the women reaching full MVC more rapidly than the men. Also, there were significant differences among the five muscle groups tested, with the wrist flexor muscle group developing MVC most quickly, while the knee extensors took the longest time to full MVC. Based upon these data it may be concluded that the time to full MVC differs between men and women, and also that the time to full MVC differs among the five muscle groups tested in this experiment.  相似文献
