教育模式要改教育效益更要提

当前正处在由应试教育向素质教育转轨的艰难阶段,素质教育的实施中也出现了不少问题.针对"现在应不应该从应试教育模式向素质教育模式转变?"以及"具体应该如何有效地促使这一转变?"等一系列问题,提出了"教育模式要改,教育效益更要提."

儿童:特殊的文学接受群体

儿童作为一个特殊的文学接受群体，呈现着不同于成人的文学接受特点。个体阅读需要、作品吸引力和成人引导是促成儿童主动的或被动的阅读动机。在阅读兴趣选择上儿童表现出明显的渐变性和群体差异性。形象思维是儿童文学接受的主要思维形式。以直接印象介入作品，从故事层面感知而不以理性去判断作品是儿童文学接受中的主要特点。与成人相比，儿童阅读活动还明显带有感性冲动性，即情感性。

Neuro-mechanical adjustments to shod versus barefoot treadmill runs in the acute and delayed stretch-shortening cycle recovery phases

In habitually shod recreational runners, we studied the combined influence of footwear and stretch-shortening cycle (SSC) fatigue on treadmill running pattern, paying special attention to neuro-mechanical adjustments in the acute and 2-day delayed recovery periods. The SSC exercise consisted of a series of 25 sub-maximal rebounds on a sledge apparatus repeated until exhaustion. The acute and delayed functional fatigue effects were quantified in a maximal drop jump test. The neuro-mechanical adjustments to fatigue were examined during two submaximal treadmill run tests of 3 min performed either barefoot or with shoes on. Surface electromyographic (EMG) activities, tibial accelerations and kinematics of the right lower limb were recorded during the first and last 15 s of each run. The main result was that neuro-mechanical differences between the shod and barefoot running patterns, classically reported in the absence of fatigue, persisted in the fatigued state. However, in the delayed recovery phase, rearfoot eversion was found to significantly increase in the shod condition. This specific footwear effect is considered as a potential risk factor of overuse injuries in longer runs. Therefore, specific care should be addressed in the delayed recovery phase of SSC fatigue and the use of motion control shoes could be of interest.     

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.     

体育非物质文化遗产福建地术拳传承模式与传承路径探析

体育非物质文化遗产是我国传统体育文化的重要组成部分,对体育非物质文化遗产的保护和传承具有重要的意义。本文运用文献资料法、田野调查法对福建地术拳的传承发展的历史、现状及传承模式和传承路径进行梳理和归纳。研究发现福建地术拳并非单纯沿用传统的自然传承模式,而是在近一个世纪的传承过程中逐渐摸索出一条“以政宣武,以商养武,以武助商”的具有自我特色的传承模式和“六进”的传承路径。     

刍议社区教育发展模式之构建

从教育创新和建模的需要出发，用模式的理论审视社区教育的科学运作与科学思维。不难看出，社区教育是全纳教育模式，社区教育是教育与社区双向发展的互动互利模式，能使教育资源在重组建模过程中功能放大，促进终身教育体系和学习型社会的构建。     

为了智慧的生长——幼儿园课程的特质与旨归

幼儿园课程的特质与旨归是为儿童的智慧生长提供机会,让儿童学会用智慧统领知识.要提升幼儿园课程的实施智慧,就要对儿童进行再发现和再认识.儿童是幼儿园课程的永恒主语.幼儿园课程应该关注幼儿园中的儿童、教师心里的"儿童"和课程内容中隐藏的"儿童",让这三个"儿童"在幼儿园课程中相遇、交谈,共同建构幼儿园课程的实施情境,并在情境中实现共同发展.     

幼儿研究性活动与教师角色的定位

幼儿研究性活动不同于一般的“主题“活动和中小学研究性学习,其自身的特征决定了幼儿教师应扮演多重角色,即正确教育理念的构建者,环境的创设者,幼儿活动的引导者、支持者、观察者,教育实践的研究者,活动方案的设计者.
