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

Cost effective, quantifiable assessment of lower extremity movement represents potential improvement over standard tools for evaluation of injury risk. Ten healthy participants completed three trials of a drop jump, overhead squat, and single leg squat task. Peak hip and knee kinematics were assessed using an 8 camera BTS Smart 7000DX motion analysis system and the Microsoft Kinect® camera system. The agreement and consistency between both uncorrected and correct Kinect kinematic variables and the BTS camera system were assessed using interclass correlations coefficients. Peak sagittal plane kinematics measured using the Microsoft Kinect® camera system explained a significant amount of variance [Rangehip = 43.5–62.8%; Rangeknee = 67.5–89.6%] in peak kinematics measured using the BTS camera system. Across tasks, peak knee flexion angle and peak hip flexion were found to be consistent and in agreement when the Microsoft Kinect® camera system was directly compared to the BTS camera system but these values were improved following application of a corrective factor. The Microsoft Kinect® may not be an appropriate surrogate for traditional motion analysis technology, but it may have potential applications as a real-time feedback tool in pathological or high injury risk populations. 相似文献

Critical Thinking, Learning and Confucius: A Positive Assessment 总被引:1,自引:0,他引:1
Hye-Kyung Kim 《Journal of Philosophy of Education》2003,37(1):71-87
In this paper I argue that Confucius' view of learning in the Analects entails critical thinking. Although he neither specified the logical rules of good reasoning nor theorised about the structure of argument, Confucius advocated and emphasised the importance of critical thinking. For Confucius reflective thinking of two sorts is essential to learning: (1) reflection on the materials of knowledge, in order to synthesise and systemise the raw materials into a whole, and to integrate them into oneself as wisdom; (2) reflection on oneself, (a) in order to ensure that such synthesis, systemisation, and integration proceed in an open-minded, fair and autonomous way, and (b) in order to integrate knowledge with the self, that is, to internalise it until it becomes oneself. 相似文献

This article describes the establishment in fall 2002 of a School of Education Research Center designed to support faculty
in increasing productivity and quality in research. Details are provided about center goals, services, staffing, space, resources,
and logistics during the first year of operation. In addition, data are shared about faculty usage of the Center, the level
of faculty satisfaction with center services in the first year, and initial increases in faculty productivity. The article
concludes with plans for continued data collection to monitor the impact of the Center, a discussion of lessons learned at
this point in the Center's development, and possibilities for the evolution of the Center.

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep. 相似文献

The ubiquity and educational potential of mobile applications are well acknowledged. This paper proposes six theory-based, pedagogical strategies to guide interaction design of mobile apps for young children. Also, to augment the capabilities of mobile devices, we used a humanoid robot integrated with a smartphone and developed an English-learning app that applied the design strategies to this environment. Our observations of children's one-on-one use support the promise of the strategies and the combined use of robots and mobile devices to be a viable option to help optimize mobile learning. 相似文献

We investigated South Korean workers’ reflections on career chance events in terms of types of chance occurrences and factors that influence how these are reacted to. A critical incident technique was used to collect data from 85 participants using an open-ended questionnaire. Various types of events that happened unexpectedly were identified through a two-dimensional framework: whether an event was relationship based or experienced based, and whether it occurred in personal areas or work areas. Influencing factors that affected the participants’ reactions were also categorized using a two-dimensional framework: internal or external, and facilitating or discouraging dimensions.

Mobile devices are highly portable, easily distributable, substantially affordable, and have the potential to be pedagogically
complementary resources in education. This study, incorporating mixed method analyses, discusses the implications of a mobile
learning technology-based learning model in two public primary schools near the Mexico-USA border in the state of Baja California,
Mexico. One school was located in an urban slum and the other in a rural village community. Empirical and ethnographic data
were collected through a series of achievement tests, observations, surveys, and interviews involving 160 s grade school children
recruited by convenience sampling. The general technology infrastructure, distinctive features of mobile learning to supplement
literacy development, profound contextual phenomena arising from the two uniquely underserved communities, and social factors
possibly influencing the educational experiences are discussed. The findings suggest that students in the rural village, seriously
lacking educational resources and technology exposure, may have benefited substantially more from mobile technologies than
urban school students possibly due to their relatively higher socio-economic status and higher parental involvement and interest
in education. In contrast, there was no evidence of interaction with parental education levels, the experience of teachers
or school principals, or the teacher’s perception or preparation of the technology. Overall, the mobile learning technology
adoption was rapid, seamless, and actively driven by the students rather than the teacher. The challenges of the phenomenal
migratory nature of most families in this unique geographical region are also discussed to benefit future studies. 相似文献

This study examines what a Korean heritage language school means to Korean immigrant families and their children, considering
Korean immigrant mothers’ perspectives on American early schooling. As part of an ethnographic research project on Korean-American
children’s peer culture in a heritage school, seven mothers, two guardians (grandmothers), and their young children were observed
and interviewed during one academic year. The analysis showed that the heritage language school functions as a social and
emotional support system, a buffer for reducing the detachment from parents, and a safety net for the Korean-American children’s
challenging lives. The Korean immigrant mothers also showed that they felt burdened by different cultural views of their children’s
behaviors, and described how their children were often considered problematic. The social and culture barriers caused by their
immigrant status profoundly influenced their reasons for sending their children to a Korean heritage language school. This
study suggests that teachers’ deep understanding of culturally different perspectives on children’s behaviors, along with
systematic social and emotional support, can help these children attain psychological well-being. 相似文献
