Manipulating generalized motor program difficulty during blocked and random practice does not affect parameter learning

Blocked practice engenders more trial-to-trial response stability, which is thought to be crucial for developing the generalized motor program (GMP) but not parameter learning (Lai, Shea, Wulf, & Wright, 2000). It was hypothesized that reducing the difficulty of the GMP might permit additional cognitive resources to be allocated to learning the parameter requirements. However, GMP theory maintains the independence of the memories governing the GMP and parameters. This notion suggests that manipulating the difficulty of the GMP should have no effect on the blocked practice participant's ability to successfully specify the appropriate parameters. Participants learned a simple or complex relative timing pattern under either blocked or random practice conditions. Smaller GMP errors were exhibited for the simple relative timing patterns, but this was not associated with improvements in parameter specification following blocked practice. A clear advantage for parameter specification was evident in transfer following random practice. Taken together, these data support the theoretical separation of the GMP and parameter processes.     

同伴关系与大学生体育锻炼习惯的关系

根据问卷调查法、数理统计法等,对同伴关系与大学生体育锻炼习惯的关系进行研究发现,大学生的锻炼同伴主要是同学朋友,在同伴进行体育锻炼时,大部分大学生会受到影响而参加锻炼;而在同伴不锻炼时,也有部分学生会受到影响放弃锻炼。大学生有体育锻炼习惯的人数比例较低,他们对同伴的影响不如没有体育锻炼习惯学生对同伴的影响大,同伴效应的负面影响大于正面影响。     

教师观念更新与教学模式改革创新的探讨——兼谈贯彻新《纲要》

实施新《纲要》要有创新精神,要更新观念、统一思想,才能创新体育课程教学模式,观念是否更新直接影响体育改革的质量。因此,高校体育教师更新观念是教学模式改革创新的前提,而教师素质的提高又是更新观念的基础。高校体育教师只有努力提高自身的综合素质,更新知识、转变观念,才能更好地实现新《纲要》的课程目标。
