Historical Analysis of Participation in 161 km Ultramarathons in North America     

Martin D. Hoffman  June C. Ong  Gary Wang 《国际体育史杂志》2013,30(11):1877-1891

Participation trends in 100 m (161 km) ultramarathon running competitions in North America were examined from race results from 1977 through 2008. A total of 32, 352 finishes accounted for by 9815 unique individuals were identified. The annual number of races and number of finishes increased exponentially over the study period. This growth in number of finishes occurred through a combination of (1) an increase in participation among runners ≥40 years of age from less than 40% of the finishes prior to the mid-1980s to 65–70% of the finishes since 1996, (2) a growth (p < 0.0001) in participation among women from virtually none in the late 1970s to nearly 20% since 2004, and (3) an increase in the average annual number of races completed by each individual to 1.3. While there has been considerable growth in participation, the 161 km ultramarathon continues to attract a relatively small number of participants compared with running races of shorter distances.  相似文献   

Facilitating teachers' professional growth through their involvement in creating context-based materials in science     

June M. George  Fred Lubben   《International Journal of Educational Development》2002,22(6):419

This paper traces the professional growth of science teachers in Trinidad and Tobago through their involvement in the production of context-based resource materials relevant to the lives of their students during workshop sessions. Grounded theory methods were used to analyse pre- and post-workshop questionnaire responses, tape-recorded group discussions and several draft lesson outlines. The findings show that professional growth is indicated by changes in the nature of the contexts chosen as lesson foci, the role of these contexts in the overall lesson design, and teachers' perceptions of contextualised teaching. Conflicts between students' cultural and scientific understandings were not addressed by these teachers.  相似文献   

EMPIRICAL SYNTHESIS OF THE EFFECT OF STANDARD ERROR OF MEASUREMENT ON DECISIONS MADE WITHIN BRIEF EXPERIMENTAL ANALYSES OF READING FLUENCY          下载免费PDF全文

Matthew K. Burns  Crystal N. Taylor  Kristy L. Warmbold‐Brann  June L. Preast  John L. Hosp  Jeremy W. Ford 《Psychology in the schools》2017,54(6):640-654

Intervention researchers often use curriculum‐based measurement of reading fluency (CBM‐R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM‐R data within a BEA by computing the standard error of measure (SEM) for the median data point from the baseline and intervention data. The median CBM‐R score from the intervention that the authors of each study identified as most effective fell within the SEM (68% confidence interval) of the baseline data approximately 30% of the time, but the ranges for the two author‐identified most effective interventions overlapped over 75% of the time. Extended analyses were consistent with the BEA results for approximately three‐fourths of the instances after considering the SEM of the baseline and intervention phases. Using matched passages did not improve the overlap of the ranges, but there was less overlap when the study used three data points per condition. Results emphasize the importance of considering SEM of CBM‐R data when comparing interventions within a BEA. Further implications for practice and future research are included.  相似文献   

The Relative Interdependency of Colloquial and Mathematical Discourses Regarding the Notion and Calculations of Limit: an Evidence-Based Cross-Cultural Study     

Dong-Joong Kim  Woong Lim 《International Journal of Science and Mathematics Education》2018,16(8):1561-1579

This study compares English- and Korean-speaking university students’ colloquial and mathematical discourses on the notion and practice of limit. There exists a lexical discontinuity in Korean with the word limit, since the mathematical word for limit is not commonly used as a colloquial word in Korean, unlike its use in English. This study discusses similarities and differences with regard to ways students in each country use the word limit in colloquial contexts and in mathematical tasks. Data include surveys and interviews, and participants’ discourses, which were analyzed using Sfard’s (2008) discursive framework. Findings indicate that the mathematical discourse of the Korean speakers was structural (i.e. formal or mathematical) and the one for the English speakers was processual. Further, the differences between the US and Korean participants’ use of limit in everyday and mathematical discourses informed the language-dependent properties of school mathematics discourses in terms of word use, routines, endorsed narratives, and visual mediators. This study discusses different discursive needs—linguistically and culturally—to support meaningful mathematical discourses.  相似文献   

Faculty Student Interaction at the Community College: A Focus on Students of Color     

June C. Chang 《Research in higher education》2005,46(7):769-802

The present study describes the level of faculty--student interaction on 2-year college campuses, examines student characteristics correlated with faculty contact, and considers how interaction may differ among racial subgroups of students. Using data collected from the Transfer and Retention of Urban Community College Students (TRUCCS) survey, a sample of 2500 students informed this research. The findings reveal generally low levels of interaction, and especially with Asian American/Pacific Islander and Latino students. Having positive perceptions of the college environment and interacting with other members of the institution, from students to academic counselors, glow the strongest positive association with faculty contact among all racial subgroups of students. Prominent among the differences is the negative relationship between perceiving racial difficulties and interacting with faculty for Asian American/Pacific Islander students. The findings provide insight in how to increase and enrich faculty interaction on these campuses to better retain underrepresented students in the educational pipeline.  相似文献   

Differential pathways to generic skills development of male and female college students in Korea     

Byung Shik Rhee  Sooji Kim 《Asia Pacific Education Review》2012,13(4):677-690

This study analyzed a stratified random sample of 1,707 senior students at 60 four-year universities in South Korea to explore the gender-specific pathways to Korean students?? development of generic skills??analytical thinking and problem-solving skills. Multiple regression analyses were performed to investigate the involvement factors differential effects on the development of students?? generic skills. The findings suggest that college student involvement plays a critical role in developing the important generic skills. Furthermore, male and female students do have different routes to the development of such skills. In the case of Korean students, at 4-year institutions of higher education, male students tend to develop generic skills more through formal and independent activities in and out of the classroom, whereas female students do so typically in an informal and interdependent way. These results call for additional scholarly investigation into gender influence on college impact and gender-dependent activities during college; moreover, they encourage institutions of higher education to adopt more gender-specific approaches to relevant institutional policies and practices.  相似文献   

Barometer for Beauty: How Cosmetic Surgery Websites Define and Visualize “What Is Beautiful”     

J. Robyn Goodman  E. Soo Rhee 《Visual Communication Quarterly》2014,21(1):25-39

The present study investigated visuals on cosmetic surgery websites to better understand how these sites depict ideal beauty. The content analysis of 90 cosmetic surgery websites found most sites used general photos and more than half used 10 or more before-and-after photos. Women outnumbered men in general photographs but not in before-and-after photographs. Brunette men and women significantly outnumbered blondes. However, there were significantly more men with dark-colored eyes, while women were significantly more likely to have light-colored eyes. Implications are discussed.  相似文献   

The influences of student engagement, institutional mission, and cooperative learning climate on the generic competency development of Korean undergraduate students     

Bo Keum Choi  Byung Shik Rhee 《Higher Education》2014,67(1):1-18

Using multilevel models, this study examined whether the strength of the association between student engagement and development of generic student competencies (GSCs) varies across Korean colleges. Data from the Korean Educational Development Institute’s 2007 national sample and from 5,445 students representing 60 four-year colleges and universities were utilized. The results indicate that a specific type of engagement is linked to a particular learning outcome, which means that not every engagement type has an equal impact thereon. The findings also suggest that in Korea, the impact on GSC of one of the student engagement types, that is, active learning, significantly varies by college mission and the peer climate of cooperative learning.  相似文献   

Development and Implementation of Science and Technology Ethics Education Program for Prospective Science Teachers     

Hyang-yon Rhee  Kyunghee Choi 《Science & Education》2014,23(5):1101-1130

The purposes of this study were (1) to develop a science and technology (ST) ethics education program for prospective science teachers, (2) to examine the effect of the program on the perceptions of the participants, in terms of their ethics and education concerns, and (3) to evaluate the impact of the program design. The program utilized problem-based learning (PBL) which was performed as an iterative process during two cycles. A total of 23 and 29 prospective teachers in each cycle performed team activities. A PBL-based ST ethics education program for the science classroom setting was effective in enhancing participants’ perceptions of ethics and education in ST. These perceptions motivated prospective science teachers to develop and implement ST ethics education in their future classrooms. The change in the prospective teachers’ perceptions of ethical issues and the need for ethics education was greater when the topic was controversial.  相似文献
