Technology’s role in learning at a commuter campus: The student perspective     

Janet A. Buckenmeyer  Casimir Barczyk  Emily Hixon  Heather Zamojski  Annette Tomory 《Journal of Further & Higher Education》2016,40(3):412-431

Patterns of technology ownership and usage, as well as skills with and preferences for various technologies, affect the college experience (Educause 2012). Students at a commuter campus of a large Midwestern public university were surveyed about technology and the learning process: 94% of the respondents believed that technology had the potential to benefit learning and 85% thought it was central to their academic success. Students credited technology-enhanced courses with increased and more effective communication with instructors, the ability to better manage course activities and expanded opportunities for practice and reinforcement. Students’ prior experiences with a course management system affected their perceptions of the role of technology and their subsequent beliefs about the benefits of its use in their university courses. Implications for administrators who make decisions about faculty development, student retention and funding for technology-enhanced course offerings are discussed.  相似文献   

地籍测量综合实习中新技术应用研究   总被引：2，自引：0，他引：2  

田毅  侯敏  付薇 《中国地质教育》2005,14(3):87-89

地籍测量成果一经土地登记即具有法律效力,直接关系着国家与私人土地产权的归属问题,因此,只有采取先进、精确的测量仪器与方法,才可以保证地籍测量最终成果的合理、准确、适时。本文认为,地籍测量实践教学可以通过转变实习指导思想,合理安排实习内容,创造必要的软、硬件条件,从而有效的引入GPS、RS、GIS等新技术,使学生了解并认识新技术,更重要的是学会如何运用新技术解决地籍测量中的实际问题。  相似文献   

基于网络的教学模式改革四议     

吕新云  崔青华 《广东广播电视大学学报》2007,16(3):17-18,32

网络教育在我国取得了重要的成果,极大地推动了我国高等教育的改革与发展。但在进一步深化和推动网络教育的过程中也出现了一些新的问题,诸如教学模式改革中的课程改革与师生关系、教学设计与时空协调、课程改革与信息技术整和等。如果这些问题得不到妥善解决,将严重制约现代运程开放教育事业的发展。  相似文献   

Reliability and validity of the Myotest® for measuring running stride kinematics     

Cyrille Gindre  Kim Hebert-Losier  Jean-Benoit Morin 《Journal of sports sciences》2016,34(7):664-670

Accelerometer-based systems are often used to quantify human movement. This study’s aim was to assess the reliability and validity of the Myotest® accelerometer-based system for measuring running stride kinematics. Twenty habitual runners ran two 60 m trials at 12, 15, 18 and 21 km·h^?1. Contact time, aerial time and step frequency parameters from six consecutive running steps of each trial were extracted using Myotest® data. Between-trial reproducibility of measures was determined by comparing kinematic parameters from the two runs performed at the same speed. Myotest® measures were compared against photocell-based (Optojump Next®) and high-frequency video data to establish concurrent validity. The Myotest®-derived parameters were highly reproducible between trials at all running speeds (intra-class correlation coefficient (ICC): 0.886 to 0.974). Compared to the photo-cell and high-speed video-based measures, the mean contact times from the Myotest® were 34% shorter and aerial times were 64% longer. Only step frequency was comparable between systems and demonstrated high between-system correlation (ICC ≥ 0.857). The Myotest® is a practical portable device that is reliable for measuring contact time, aerial time and step frequency during running. In terms of validity, it provides accurate step frequency measures but underestimates contact time and overestimates aerial time compared to photocell- and optical-based systems.  相似文献
