让语文学科“分分家”，如何?

尽管新课程标准将语文学科的工具性和人文性"并驾齐驱",然而翻开各种各样的语文杂志,还时不时地看到厚此薄彼的论争。其实早在此前的教学大纲中,就已将二者并列提出,但论争却从未止息。工具论者更倾向于理性的推断、客观的剖析。读他们的文章,你常常被其深厚的学术功力所折服。人文论者则慷慨激昂、高屋建     

柴可夫斯基音乐作品钢琴套曲十一月《雪橇》艺术欣赏与教学

音乐是震撼人心的力量，它能引人向上，教人优秀，使人快乐，驱逐不良的情绪；音乐是睿智的表达，是纯净的象征，是对美的描述，是对善良的感知，是质朴和真实的展示，是诗的歌唱。柴可夫斯基的音乐作品钢琴套曲十一月《雪橇》就是对这些描述的总结和概括。     

业余教练员培养机制的构建与发展对策

业余教练员的培养是我国竞技体育可持续发展的基础,通过问卷调查法、访谈法和数理统计法等方法对上海、江苏等地区的教练员的现状进行了调查,结果表明:(1)训练单位在业余教练选拔中主动性不足,公开招聘教练员成为各单位理想的选拔方式;(2)业余教练员培训中职前、在职和职后教育的衔接不紧,探索有效的教练员教育模式成为业余教练员培养的重要环节;(3)科学的考核指标和合理的聘任目标是激励教练员提高执教水平的重要保证;(4)健全的教练员信息保障机制可以完善教练员的知识结构,更新教练员的训练理念,是业余教练员培养的重要组成部分;并提出了健全教练员培养制度,建立教练员流动机制等对策。     

Changes in the perception of action possibilities while climbing to fatigue on a climbing wall

In two experiments we examined changes in the perception of action possibilities as a function of exertion. In Experiment 1, participants repeatedly climbed on a climbing wall in a series of trials that progressively increased in number to 10 trials, resulting in increased exertion. Before and during climbing, the participants judged their maximum reaching height and perceived exertion. On a separate day, participants climbed another 10 trials while performing actual maximum reaches. Higher perceived exertion was associated with decreases in perceived maximum reach while the actual reaches did not decrease. However, the perceptual changes occurred early during task execution when the participants were not yet fatigued. When exertion set in, neither perceived nor actual maximum reaching appeared to be affected. In Experiment 2, we included exhaustion trials. The findings replicated the early changes in perception observed in Experiment 1, which may be explained by hands-on experience with the task. Furthermore, while climbing to exhaustion, perceptual judgements largely changed in keeping with changes in the actual maximum reach. Thus, there appeared to be a functional relationship between participants' actual action capabilities, rather than their state of physical fatigue per se, and perceived action possibilities.     

A simple and effective method for total RNA isolation of appressoria in Magnaporthe oryzae

Appressorium formation is an important event in establishing a successful interaction between the rice blast fungus, Magnaporthe oryzae, and its host plant, rice. An understanding of molecular events occurring in appressorium differentiation will give new strategies to control rice blast. A quick and reliable method to extract total RNA from appressorium is essential for studying gene expression during appressorium formation and its mechanism. We found that duplicate film is an efficient substratum for appressorium formation, even when inoculated with high density conidia. When inoculated with conidia at 1×106ml-1, the percentages of conidium germination and appressorium formation were (97.98±0.67)% and (97.88±0.45)%, respectively. We applied Trizol before appressorium collection for total RNA isolation, and as much as 113.6 pg total RNA was isolated from the mature appressoria at 24 h after inoculation. Functional analysis of two genes, MNH6 and MgATG1, isolated from the cDNA subtractive library, revealed that the quantity of RNA was good enough to construct a cDNA (complementary DNA) library or a cDNA subtractive library. This method may be also applicable for the appressorium RNA isolation of other pathogenic fungi in which conidia differentiate into appressoria in the early stages of host infection.

心理定势与物理教学

1　心理定势心理定势也叫心向,是指对活动的特殊心理准备状态,定势对知觉的影响,表现为一个人以特殊的心理状态,反映刺激物。定势对思维的影响表现为,总是用已掌握的思维方式来对待活动或对待活动的倾向性。心理定势对学习新知识或解决新课题的影响,可能是积极的,也可能是消极的。2　心理定势的积极作用与消极作用的表现形式心理定势的产生,是由日常生活经验,认知结构等信息,在思维活动、技能训练中,经反复验证或练习,或者是社会舆论对某一问题的反复认同,而形成的。它对某一问题的解决,可能起积极作用,也可能起消极作用。学生学习新知识离…

医院改扩建存在的问题与对策

随着我国医疗卫生改革的不断深入和国民经济的不断发展,医院都共同面临着原址改扩建的艰巨任务。因为城市用地越来越紧张,医疗服务人群不断增长,医疗技术设施不断更新,各种疾病的发展、研究与治疗等,都给医疗建筑提出了更复杂更安全的使用需求。有的医院历史悠久,古建筑、古树木众多。既要保证古文化的遗留又要合理有效地进行扩建,这是本文讨论的主要问题。     

对普通高校建立教学质量监控体系的思考(北京市教育科学“九五”规划重点课题《普通高等学校教学评价规范化系统化研究与实践》阶段成果)
