试论阅读对听力提高的作用     

王丽 《零陵学院学报》2005,(3)

听是英语语言能力的一个重要方面,而听力能力的培养和提高不仅仅依靠大量的听力练习,在很大程度上,它还依靠大量的阅读。本文通过对阅读在英语学习者熟悉各种语篇类型、掌握句型结构和固定搭配以及了解相关英语背景知识等方面的分析,论证了阅读对提高听力能力的促进作用,并在此基础上就如何通过阅读提高听力能力提出了几点建议,以期推进英语听力教学的发展。  相似文献

Knee joint position sense of roller hockey players: a comparative study     

João Venâncio  Diogo Lopes  Joaquim Lourenço  Fernando Ribeiro 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(2):162-168

This study aimed to compare knee joint position sense of roller hockey players with an age-matched group of non-athletes. Forty-three male participants voluntarily participated in this cross-sectional study: 21 roller hockey players (mean age: 23.2 ± 4.2 years old, mean weight: 81.8 ± 9.8 kg, mean height: 180.5 ± 4.1 cm) and 22 age-matched non-athletes (mean age: 23.7 ± 3.9 years old, mean weight: 85.0 ± 6.2 kg, mean height: 181.5 ± 5.0 cm). Knee joint position sense of the dominant limb was evaluated using a technique of open-kinetic chain and active knee positioning. Joint position sense was reported using absolute, relative and variable angular errors. The main results indicated that the group of roller hockey players showed significantly lower absolute (2.4 ± 1.2º vs. 6.5 ± 3.2º, p ≤ 0.001) and relative (1.7 ± 2.1º vs. 5.8 ± 4.4º, p ≤ 0.001) angular errors in comparison with the non-athletes group. In conclusion, the results from this present study suggest that proprioceptive acuity, assessed by measuring joint position sense, is increased in roller hockey players. The enhanced proprioception of the roller hockey players could contribute to injury prevention and improved performance during sporting activities.  相似文献

Special Issue Introduction: Career and Life Planning Key Feature Within Comprehensive Guidance Programs     

Harry N. Drier 《Journal of Career Development》2000,27(2):73-80

Career and life planning is viewed as a process that starts early in the elementary school through adult life and it should be at the heart of any guidance program. This journal discusses the value and process ideas at each of the school and grade levels. The authors also discuss how parents, employers, and teachers enhance the career planning process by expanding student options, encouragement, motivation, mentoring, and providing career life experiences. Career planning is viewed as a structured and expected series of events and activities a student would go through as a part of their school experience. It forwards the idea that to assure all youth have a plan for life transition and success takes state department of education policy and support, local district expectations, time, and resources, and students who see the value in participating. The counselor is viewed as the key agent in such a program and needs to demonstrate that early, continuous and high quality life planning improves not only academic achievement, but life and employment success.  相似文献

Reciprocal elucidation: a student-led pedagogy in multidisciplinary undergraduate research conferences     

Helen Walkington  Jennifer Hill  Pauline E. Kneale 《高等教育研究与发展》2017,36(2):416-429

There is no previous study of the benefits of attending a national multidisciplinary conference dedicated to undergraduate researchers, despite the growing number of such conferences internationally. This paper addresses the gap in knowledge of the learning gains from these conferences, and reveals a student driven learning process, a multidisciplinary signature pedagogy. It presents the results of 90 in-depth interviews with student conference participants conducted over three consecutive years of a multidisciplinary National Conference of Undergraduate Research (2012–2014). This paper uniquely captures the student voice on their perceived learning gains from this experience. The results reveal that some students co-create a pedagogy of Foucauldian reciprocal elucidation, through a sense of ‘unfinishedness’, allowing them to reflect on their own learning in the light of divergent perspectives, questions and frames of reference. Bidirectional exchange of ideas and insights enabled students to ask and answer questions that transformed each other’s thinking, allowing them to arrive at understandings they could not have achieved by themselves. The opportunity to present research in an authentic setting beyond disciplinary and institutional contexts developed students’ skills and confidence, giving additional value over and above the recognised benefits of engaging in research. The undergraduate research conference is framed as a threshold experience for the development of self-authorship. Significant implications for practice include supporting constructive dialogues between students and the creation of authentic and professional multidisciplinary contexts for sharing research.  相似文献   

一种新的基于灰度冗余的红外图像均衡技术   总被引：1，自引：0，他引：1  

顾建雄  刘振来  张志荣 《河西学院学报》2011,27(5):66-71

针对红外图像的特点,文章提出一种新的基于灰度冗余的红外图像均衡技术.通过设定合适的阈值,将图像灰度直方图中像素分布为零的灰度级进行完全压缩,将小于阈值的灰度级映射到最近的大于阈值的灰度级,然后将有效灰度级做基于幂函数的拉伸变换后进行直方图均衡,最后将均衡后的图像灰度级等间距排列.该算法在压缩灰度冗余的同时进行直方图的无损均衡,保留了图像细节部分,避免了常规直方图均衡所带来的图像细节丢失和灰度断层现象,提高了图像质量.  相似文献
