初中数学"探究式学习"的探索

倡导自主、合作、探究的学习方式,促进学生在"自主"中求知,在"合作"中获取,在"探究"中发展.探究性学习是学生必不可少的学习基本形式,学生是在不断地探索发现过程中获得发展的,而探究学习是培养主动、积极的知识探究者.开展探究性学习,是为了培养学生的创新精神和实践能力,真正实现素质教育的需要.     

浅谈大学教育中的人文缺失及对策

高校教育的目的不仅是对文化知识的的传播,同时也要培养大学生精神、能力等"成人"教育目的.但是我国很多大学过多的注重了学生的专业知识的传授,忽视了对大学生的人文精神的培养、对人文知识的讲解一带而,不利于培养大学生全面素质的发展.本文针对大学教育中人文缺失的原因及对策进行论述.     

在"猜猜凑凑"中培养学生的创新精神

创新是民族的灵魂,是社会进步的主旋律,这已经成为人们的共识.但是,创新精神的培养不是听一个报告、搞一次讲座就会有的,需要经过长期训练,潜移默化,耳濡目染.所以,培养学生的创新精神,我们必须从小抓起,从课堂教学抓起.在课堂教学中,教师应该努力营造积极民主的教学氛围,"越来越少的传递知识,越来越多的激励思考",培养学生的质疑精神、敢想的品质和善思的能力,允许他们犯错误,宽容他们的失败,为他们走上创新之路打下良好的基础.数学教学中的"猜猜凑凑"不失为一种培养学生的创新精神的好方法.     

公共教育学教学中批判性思维的培养

公共教育学(简称"教育学")教学面向未来教师,培养批判性思维具有长远的意义.批判性思维包括批判精神和批判性思维技能,批判精神的人格特质可以在培养批判性思维技能的过程中形成和强化.围绕教科书的观念和言说,教育学教学可以从四个方面指导学生思考教科书文本,发展批判性思维.     

大学精神传统之研究

大学精神是大学文化诸现象中的内在逻辑，发挥着支持知识创造、批判和营造宽松自由的学术环境，促进大学发展的重要功用。大学精神主要包括自立自治、学术自由和人文主义精神传统。     

摒弃"模板"尝试"词块"——大学英语写作教学的有效切入点

初中数学中统计与概率的教学研究

我国在初中开设了"统计与概率"板块,教育价值在于培养学生的数学应用能力和批判精神,推动信息技术的使用.初中数学"统计与概率"的学习方式主要有:动手实践、自主探索和合作交流.     

点"情"激"趣",引领探究实践三步走——谈语文综合性学习中三个阶段的教学

新课标这样指出:"语文综合性学习有利于学生在感兴趣的自主活动中全面提高语文素养,是培养他们主动探究、团结合作、勇于创新精神的重要途径."这就决定了"综合性学习"是扎根于学生的情感需要,并在此基础上展开的一项实践活动.这项实践活动重视学生主动积极的参与精神,突出学生的自主性,并强调合作精神,注意培养学生的能力.     

春风化雨,润物无声——创建"书香校园"之我见

本文结合我校创建"书香校园"做法及我自己的思考写成的.阐述如何摒弃外界环境对学生的负面影响,如何创建"书香校园"来丰富学生知识、开阔学生的视野、培养学生学习兴趣、陶冶学生的情操.     

浅谈"在语文教学中培养学生的自学能力"

叶圣陶先生说:"凡为教者必期于达到不须教.教师所务唯在启发引导,俾使学生逐步增益其智能,展卷而自能通解,执笔而自能合度."针对于此,在语文教学中怎样提高学生的自学能力和培养自学习惯是教学改革的一个重要课题.从"调动学生学习的主动性和积极性,重视发展学生的智力;指导学生掌握规律性的知识,重视交给学生学习的方法;培养学生预习的能力和习惯,改进课堂教学,提高教学效果"三方面入手,有的放矢的培养学生的自学能力.     

转炉炉壳热应力分析

根据实际转炉建立实体模型。以有限元为手段,考虑了炉衬和炉壳材料的物性参数随温度变化的特点和炉衬与炉壳之间膨胀间隙,计算了转炉炉壳在温度载荷和炉衬膨胀压力同时作用下的热应力。所得结果可为转炉炉壳设计提供依据。

Results of treatment of cancer of the cardia

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients.     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Effect of antibiotics of chemotaxis of human leukocytes

The effect of 20 different antibiotics on chemotaxis by human neutrophils was studied. Human leukocytes incubated with chloramphenicol, rifampin, sodium fusidate, and tetracyclines in vitro showed markedly depressed migration. The mechanisms by which these antibiotics affect leukotaxis are discussed.     

Quality of life of relatives of mental patients

Usage of quality of life of psychiatric patients' relatives as the parameter of estimation of the quality of psychiatric care is considered. By means of standard questionnaire elaborated by the authors as well as by means of both individual and group conversations the quality of life was analyzed in 40 relatives which lived together with psychiatric patients. Different spheres of their life and difficulties (financial, social-psychologic, production) were examined in families with such patients. The defects of psychiatric care that had direct influence on the quality of life of the psychiatric patients' relatives are outlined.
