论儿童的人格

人格是人的规定性,社会性是人的基本规定性。人从儿童期开始,就具有社会性,就具有人格。儿童的人格,处于全部人格发展的基础地位。它具有基础性、可塑性、动力性和稚弱性等特点。肯定儿童的人格及其特点,才能实施“人格化”教育,才能使儿童的“人格权”得到真正维护。     

网络环境下的教师教学评价问题研究

随着计算机网络等信息技术参与到课堂教学过程中,整个教学环境发生了质的变化,这种变化必然带来对教师的新的要求.新的要求体现在对教师的评价中,也带来了教师教学评价的变化.对网络环境下教学评价应包括信息技术技能、引导作用、课堂教学设计能力、教学监控能力和利用网络开展教学科研的能力.同时还应将新的信息技术运用于教师教学评价过程中,对于教师评价方法进行丰富和创新.     

职业教育与乡土中国的改造

长期的城乡二元经济结构和以城市为中心的政策导向造成了乡土中国与城市中国之间的天壤之别,农村成了被世人遗忘的角落,一个“土”字即能生动体现出农民所遭受的歧视和不公正待遇。中国现今仍是一个

改性有机玻璃热性能的研究

采用甲基丙烯酸甲酯、甲基丙烯酸、苯乙烯及二乙烯苯组成四元共聚体系,通过本体聚合制备出一系列耐热透明有机玻璃板材。研究了各改性组分对共聚物热形变温度的影响,测定了共聚物的玻璃化温度,结果表明,苯乙烯用量２５－３０％,甲基丙烯酸１０－１２％,二乙烯苯１－２％时的改性效果较好。     

标准三维属性空间视域下的高校行政管理工作标准体系构建

我国教育标准建设已经历了25 年,但仍然存在不规范、不均衡等很多不足。依据波兰学者沃吉次基标准三维属性空间概念,构建高校行政管理工作标准体系的级别维、对象维和内容维,特别是内容维上“三本两化”标准体系,对一直困扰高校行政管理工作缺乏检查、督办、考核、追责依据的现象,提供了比较科学的依据,可以填补我国高校层面教育标准建设的空白。     

A Hands-On Organ-Slicing Activity to Teach the Cross-Sectional Anatomy

The presentation of pre-sliced specimens is a frequently used method in the laboratory teaching of cross-sectional anatomy. In the present study, a new teaching method based on a hands-on slicing activity was introduced into the teaching of brain, heart, and liver cross-sectional anatomy. A randomized, controlled trial was performed. A total of 182 third-year medical students were randomized into a control group taught with the prosection mode (pre-sliced organ viewing) and an experimental group taught with the dissection mode (hands-on organ slicing). These teaching methods were assessed by testing the students' knowledge of cross-sectional specimens and cross-sectional radiological images, and analyzing students' feedback. Using a specimen test on three organs (brain, heart, and liver), significant differences were observed in the mean scores of the control and experimental groups: for brain 59.6% (±14.2) vs. 70.1% (±15.5), (P < 0.001, Cohen's d = 0.17); for heart: 57.6% (±12.5) vs. 75.6% (±15.3), (P < 0.001, d = 0.30); and for liver: 60.4% (±14.5) vs. 81.7% (±14.2), (P < 0.001, d = 0.46). In a cross-sectional radiological image test, better performance was also found in the experimental group (P < 0.001). The mean scores of the control vs. experimental groups were as follows: for brain imaging 63.9% (±15.1) vs. 71.1% (±16.1); for heart imaging 64.7% (±14.5) vs. 75.2% (±15.5); and for liver imaging 61.1% (±15.5) vs. 81.2% (±14.6), respectively. The effect sizes (Cohen's d) were 0.05, 0.23, and 0.52, respectively. Students in the lower tertile benefited the most from the slicing experiences. Students' feedback was generally positive. Hands-on slicing activity can increase the effectiveness of anatomy teaching and increase students' ability to interpret radiological images.
