以认知语言学为理论框架,采用定性描述和例证法,从概念、意义、兴趣等认知因素思考英语语法教学,认为教师应在实际教学过程中力求把抽象概念、规则具体化,让看似复杂抽象的语法现象变得浅显易懂且容易为学生接受和记住,调动学生学习语法的积极性和能动性,提高学生语法学习的效果。  相似文献

二语习得研究中对显性与隐性学习的关系存在着不同的认识,但从基于认知心理学对二语语法学习所作的研究来看,显性和隐性学习是两个相互独立又相互依存的学习机制.因此,在二语语法教学中,应把显性和隐性学习有机结合起来,采用动态平衡的语法教学模式,使两种学习机制的效用相互转化,相互作用,共同提高语法教学的效率.  相似文献

初中学生的知识结构、认知特点、年龄特征决定其在数学学习过程中有自身的发展规律和模式.初中数学教学要有效地促进学生数学学习,就必须在充分分析影响学生数学学习的各种因素的基础上,针对学生数学学习业绩具有影响力的本质因素进行教学.学生学习数学知识的认知心理特征和由不同性质的学习内容所决定的不同学习方式,是影响学生的数学学习最本质的因素.文章就初中学生的认知心理和知识结构两方面,对初中学生的数学学习过程进行分析.  相似文献

在以培养语言交际能力为主的素质教育背景下,一些英语教师误认为现在的中学英语教学中语言基础知识教学特别是语法教学已经不重要了,但实际上语法教学是帮助学生学得语言规则,帮助其习得外语的,从而提高语言运用能力.所以英语教师在实践中要坚持实践性、针对性、渐进性等原则,注意理解记忆学习法、归纳总结学习法、任务式学习法等具体教学要求,摆正语法教学在整个英语教学中的地位.  相似文献

大学毕业后,我从事的第一项工作是培训初中英语教师.那时的初中英语教学以”语法教学”和”翻译教学法”为主,此类教学方法培养出的学生语法能力强,但听、说、写的能力差.培训好初中英语教师就意味着无数学校的学生能在教师的指导下改变不恰当的学习方法,真正体验到学习语言的快乐.  相似文献

高职教育注重学生系统知识的掌握及技能的运用,学生的学习认知活动不仅包括认知事物、掌握知识进行的智力活动,也包括认知过程中的兴趣、情感、意志、欲望和性格等非智力因素活动.应发掘高职语文教学中的教学资源,培养学生的非智力因素,提高学生的学习效能和教学质量.  相似文献

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.  相似文献

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.

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.  相似文献

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.  相似文献
