我国高等教育面向21世纪教学改革的优秀成果--"面向21世纪教学内容和课程体系改革计划系列研究报告"简介     

林文 《中国大学教学》2002,(6):37

为了迎接21世纪我国和世界各国社会、经济、科技快速发展对高等教育培养新型人才的挑战,20世纪90年代中期,原国家教委制定和实施了《高等教育面向21世纪教学内容和课程体系改革计划》.该计划覆盖了文科、理科、工科、农科、医科、财经、政法、外语等科类,共立项221个大项目,985个子项目,有1万多名校(院)长、院士、教授、教师以及教学管理和研究人员参加了这些教学改革项目的研究与实践,历时3～5年,取得了丰硕的成果.正如前教育部副部长周远清同志指出的,这些成果"对于21世纪初叶我国高等教育的教学改革和人才培养质量的提高具有重要意义和指导作用".  相似文献   

阅读教学与学生的个性发展     

林文 《中国小学语文教学论坛》2004,(34)

面对社会发展的需要,语文课程在课程目标和内容、教学观念和学习方式等方面,都反复强调要发展学生的个性。那么如何在阅读教学中发展小学生的个性呢?一是把学生看成是完整的、独特的人要发展学生个性,首先要摒弃那种以统一规格去制造“标准件”的教育模式,而应从研究学生的差异性入手,把学生看成完整的、独特的人。珍视学生的特性,培养具有独特个性的人,应成为我们对待学生的基本态度,并在阅读教学实践中创造发展学生个性的空间。二是在阅读教学的过程中发展学生的个性阅读教学的过程包括课前预习、课堂教学、课后延伸、阅读评价等,在阅读教…  相似文献   

Basic fibroblast growth factor alleviates brain injury following global ischemia reperfusion in rabbits   总被引：9，自引：0，他引：9

The aim of this study was to explore the protective effect of basic fibroblast growth factor (bFGF) on brain injury following global ischemia reperfusion and its mechanisms. Brain injury following global ischemia was induced by four vessels occlusion and systemic hypotension. Twenty-four rabbits were randomized into three groups: group A, only dissection of vessels; group B, intravenous infusion of normal saline after reperfusion for 6 h; group C, 30 μg/kg bFGF injected intravenously at the onset of reperfusion, then infused with 10 μg/(kg·h) for 6 h. Serum neuron specific enolase (NSE), S-100B, tumor necrosis factor-α(TNF-α), interleukin-1 (IL-1), interleukin-8 (IL-8) were measured before ischemia, 30 min after ischemia, 0.5, 1, 3, 6 h after reperfusion. Brain water content was determined and cerebral histopathological damages were compared. NSE and S-100B were increased 1 h after reperfusion and reached their peaks 6 h after reperfusion, but were much higher in group B than those in group C 3, 6 h after reperfusion. In groups B and C, TNF-a was increased after ischemia and IL-1 and IL-8 were increased significantly 0.5 h after reperfusion, then reached their peaks 6 h, 3 h, 6 h after reperfusion respectively. TNF-a and IL-8 at the time points of 1 h and 3 h and IL-1 at 3 h and 6 h in group C were correspondingly lower than those in group B. These indices in group A were nearly unchanged. There were less severe cerebral histopathological damages in group C compared with group B, but no difference in brain water content. It could be concluded that bFGF alleviates brain injury following global ischemia and reperfusion by down-regulating expression of inflammatory factors and inhibiting their activities.  相似文献

Objective: To observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC. Methods: The clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical pTMN stage. Survival curves were traced by using Kaplan-Meier methods. Results: Most GSC (32/37) was detected in patients who had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=1 1.48, P＜0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage Ⅰ, 60% (3/5) for stage Ⅱ, 14.2% (1/7) for stage Ⅲ, and 0% (0/5) for stage Ⅳ respectively.The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0m vs 13.0m, xL2=36.31, P＜0.01), the median survival time of stage Ⅳ patients with radical resection was 23.8months. Conclusions: Without remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage Ⅳ GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth Ⅱ reconstruction procedure at 15-20 years.  相似文献   

解放思想 勇于探索——从自然科学史看实践是检验真理的唯一标准     

汪子春  林文照 《历史教学(高校版)》1979,(12)

科学,不论是自然科学或社会科学,作为人们认识客观世界的矛盾运动及其发展规律的知识体系,总是不断扩大,不断前进,永无止境的.客观世界没有不可探索的领域.但是在科学发展的历史上,往往由于反动统治阶级设置的种种戒律,或者由于人们认识上受形而上学的束缚,人为地形成了某些"禁区",对科学的发展起了严重的阻碍作用.因此人们为要在深度和广度上认识客观世界的发展规律,就必须解放思想,勇于  相似文献

英语中十二个月名称的由来     

林文 《高中生》2002,(3)

公历一年中有十二个月,但不少人并不知道十二个月的英语名称的来历。公历起源于古罗马历法。古罗马历法原来只有十个月,古罗马皇帝决定增加两个月放在年尾,后来朱里斯·凯撒大帝把这两个月移到年初,成为一月、二月,原来的一月、二月便成了三月、四月,其余依次类推。这就是今天全世界沿用的公历。  相似文献
