穆俊 《科教文汇》2014,(7):83-84

随着计算机技术以及信息技术的快速发展与普及,用人单位对办公自动化的要求也逐渐提高,其中“计算机文化基础”课程教学,在提高学习者计算机素质中的重要性是不言而喻的。概念图是一种新型的教学策略与教学工具,通过其在计算机文化基础教学中的运用,不仅能够辅助教学内容的设计,充分展示与分析教学内容,还能对计算机文化基础教学进行评价,优化教学的过程,提高教学效果。  相似文献   

Circadian rhythm effect on physical tennis performance in trained male players

To determine the effect of circadian rhythm on neuromuscular responses and kinematics related to physical tennis performance, after a standardised warm-up, 13 highly competitive male tennis players were tested twice for serve velocity/accuracy (SVA), countermovement vertical jump (CMJ), isometric handgrip strength (IS), agility T-test (AGIL) and a 10-m sprint (10-m RUN). In a randomised, counter-balance order, tennis players underwent the test battery twice, either in the morning (i.e., AM; 9:00 h) and in the afternoon (i.e., PM; 16:30 h). Paired t-tests were used to analyse differences due to time-of-day in performance variables. Comparison of morning versus afternoon testing revealed that SVA (168.5 ± 6.5 vs. 175.2 ± 6.1 km · h^?1; P = 0.003; effect size [ES] = 1.07), CMJ (32.2 ± 0.9 vs. 33.7 ± 1.1 cm; P = 0.018; ES = 1.46), AGIL (10.14 ± 0.1 vs. 9.91 ± 0.2 s; P = 0.007; ES = 1.23) and 10-m RUN time (1.74 ± 0.1 vs. 1.69 ± 0.1 s; P = 0.021; ES = 0.67) were significantly blunted during the morning testing. However, IS was not affected by time-of-day (P = 0.891). Thus, tennis performance may be reduced when competing in the morning in comparison to early evening. Therefore, coaches and tennis players should focus on schedule the SVA, power, speed and agility training sessions in the afternoon.  相似文献   

Sprint kayaking and canoeing performance prediction based on the relationship between maturity status,anthropometry and physical fitness in young elite paddlers     

Daniel López-Plaza  Fernando Alacid  José María Muyor  Pedro Ángel López-Miñarro 《Journal of sports sciences》2017,35(11):1083-1090

This study aimed to identify the maturity-related differences and its influence on the physical fitness, morphological and performance characteristics of young elite paddlers. In total, 89 kayakers and 82 canoeists, aged 13.69 ± 0.57 years (mean ± s), were allocated in three groups depending on their age relative to the age at peak height velocity (pre-APHV, circum-APHV and post-APHV) and discipline (kayak and canoe). Nine anthropometric variables, a battery of four physical fitness tests (overhead medicine ball throw, countermovement jump, sit-and-reach test and 20 m multistage shuttle run test) and three specific performance tests (1000, 500 and 200 m) were assessed. Both disciplines presented significant maturity-based differences in all anthropometric parameters (except for fat and muscle mass percentage), overhead medicine ball throw and all performance times (pre > circum > post; P < 0.05). Negative and significant correlations (P < 0.01) were detected between performance times, chronological age and anthropometry (body mass, height, sitting height and maturity status), overhead medicine ball throw and sit and reach for all distances. These findings confirm the importance of maturity status in sprint kayaking and canoeing since the more mature paddlers were also those who revealed largest body size, physical fitness level and best paddling performance. Additionally, the most important variables predicting performance times in kayaking and canoeing were maturity status and chronological age, respectively.  相似文献

河北宋金剔花瓷器赏析     

穆青 《收藏》2008,(3):62-67

剔花是宋代出现的一种陶瓷装饰新工艺，主要用在一些需要使用化妆土的粗胎瓷器上。其工艺一般是先在胎体表面施一至两层白化妆土，趁化妆土未干时用尖锐的工具迅速划出花纹轮廓，紧接着用铲状工具将花纹以外的化妆土剔掉，最后施透明釉入窑焙烧。剔花装饰巧妙地利用白色化妆土与深色胎体之间的反差来突出纹饰，与传统的划花装饰相比，不仅花纹显得更加醒目，而且还具有一定的立体感。  相似文献

‘We are more than EFL teachers – we are educators’: emancipating EFL student-teachers through photovoice     

Luis S. Villacañas de Castro 《Educational Action Research》2017,25(4):610-629

The prevailing pedagogical orientations of English as a foreign language (EFL) education in Spain oppress learners intellectually in ways that are counterproductive to their learning. As a reaction to this, 129 EFL student-teachers (STs) took part during the 2013/14, 2014/15, and 2015/16 academic years in a workshop which drew on the methodology of participatory action research and on photovoice as a data-creating strategy, in order to emancipate these STs intellectually, boost their EFL development, and offer an alternative critical model for their future EFL teaching. The research was assessed collectively through a variety of qualitative strategies. Results showed that the photovoice workshop created a rich and meaningful context for EFL learning, one which enabled the STs to fully actualize their intellectual potential by producing knowledge collectively, thereby setting a memorable educational example for their own future teaching.  相似文献
