While there continues to be a proliferation in the number of studies conducted on various aspects of distance education, we are often left with little understanding of the holistic planning and effects of it. This paper draws lessons learned from the literature on distance education over the past five years. This review did not seek to be exhaustive in presenting the findings of every study, but instead focuses on specific instruction we can take from past research at the institutional, faculty, and student levels.  相似文献

This paper examined the direct and interaction effects of students’ learning and performance‐avoidance goal orientations on their psychological wellbeing and a moderating role of students’ gender in these relationships. Using 564 self‐reports of freshman college students in a Thai university, we found students’ psychological wellbeing to be positively related to their learning goal orientation and negatively related to their performance‐avoidance goal orientation. Additionally, the negative relationship between students’ performance‐avoidance goal orientation and psychological wellbeing was stronger for men than women. Lastly, differences in students’ psychological wellbeing between men and women became more pronounced with increases in learning goal orientation for students with low levels of performance‐avoidance goal orientation, but not for students with high levels of performance‐avoidance goal orientation. These findings were obtained after controlling for students’ grade point average and academic program.  相似文献

“灰蒙蒙的天空、灰蒙蒙的跑道、一个以时代构形标准而言已经算不上前卫的机体,起落架收起,看来一次司空见惯的平凡飞行又开始了。然而不寻常的是,在大约2万米的对/平流层交界处,飞机却仍在加速,尾流也开始呈现规则的点状分布……接下来的事情在超出人们视线的同时也超出了想像:在不断的加速中,飞机居然突破了十万米的高度(世界运动委员会制定的最低太空高度),  相似文献

Since the introduction of martial arts in the United States, the sport of Taekwondo (TKD) has rapidly grown and developed. Although the elevated interest in this sport has increased the magnitude of the TKD market, no systematic studies have been conducted to investigate the market demand variables associated with TKD schools in North America. To a great extent, lack of study has been due to the unavailability of a viable measure. The purpose of this study was to identify the dimensions of market demand for TKD schools and develop the Scale of Market Demand Associated with Taekwondo School (SMD-TKD). Research participants (N = 205) were TKD school members who were 18 years and older from 22 TKD schools in major cities of Florida. A factor analysis using principal component extraction and varimax rotation produced six factors with 51 items returned (i.e., Personal Benefits, School Operation, Instruction Quality, Program Offering, Locker Room, and Cultural Learning). Multiples regression analysis revealed that all market demand factors, except for Program Offering and Cultural Learning, were positively (p < .05) predictive of TKD consumption, suggesting that the SMD-TKD is useful for marketing studies on TKD consumers.  相似文献

This study examines the factors that influence people's adoption and use of a digital library system and tests the applicability of the Technology Acceptance Model (TAM) in the context of developing countries. Using data from a survey of 16 institutions in Africa, Asia, and Central/Latin America (N = 1082), a path analysis revealed that perceived ease of use of the library system had a significant impact on perceived usefulness, which ultimately led to behavioral intention to use. In addition, the study examined the similarities and differences in the significant predictors of the digital library acceptance across countries and continents. Further, the current study suggests that external variables that affect perceived ease of use and usefulness need to be considered as important factors in the process of designing, implementing, and operating digital library systems. Such consideration will help decrease the mismatch between system design and local users’ realities, and further facilitate the successful adoption of digital library systems in developing countries.  相似文献

Abstract

Currently, only epidemiological injury data have been reported for the new extreme sport of aggressive inline skating, or trick skating. No studies have examined the biomechanics of this sport, which involves repetitive jumping and landing from railings, ramps, and ledges, often over 1 m in height. We present results of a pilot study that examined the effect of skater experience and lower extremity biomechanics on energy absorption ability, and observed balance strategies used during two basic tricks. In these tricks, the skater jumps onto an elevated rail and maintains balance while standing in a single position (stall) or sliding along the rail (grind). Lower extremity joint kinematics, impact force characteristics, and general movement behaviours were examined during landing and balance phases. Ten male skaters performed ten stalls and ten frontside grinds on an instrumented grind rail, capable of measuring vertical force. Vertical impact force was found to decrease with increasing skater experience in stalls (r = ?0.84, P = 0.002) and grinds (r = ?0.84, P = 0.009). This might imply that less-experienced skaters are (subconsciously) more concerned about maintaining balance than refining technique to minimize impact force. Similar to drop landing experiments, peak impact force decreased with increasing knee flexion during stalls (r = ?0.65, P = 0.04). During stalls, skaters demonstrated classic balance maintenance strategies (ankle, hip, or multi-joint) depending on trick length. During grinds, skater centre of mass never passed over the rail base of support, suggesting the use of momentum produced from obliquely approaching the rail.  相似文献
