生产实习是一个复杂的教育过程,是高等工科院校培养学生工程实践能力的重要教学环节。因此,加强实习教学对担负直接为国家培养工程技术人才任务的工科院校来说,是十分必要的。工科院校的毕业生必须具有科研、设计的初步能力。基于这样的要求,生产实习的目的是使学生深入了解工厂的设备和工艺,熟悉生产过程,学会本专业的实际生产操作本领,加深对理论知识的理解,理论联系实际,培养良好的道德品质和献身精神, 相似文献

新建工科院校应用型工程教育探讨 总被引:12,自引:3,他引:9
黑龙江工程学院是一所新建工科院校,是世纪之交一批由高工专升本的教学型工科院校之一.这批工科院校的产生是在我国经济快速发展、高等教育进入大众化阶段的社会历史背景下,高等工程教育新的结构调整和分工.可以说,这一类型的工科院校不应是原来专科的简单放大和拓展,也不应盲目攀高进行脱胎换骨的改造,更不能亦步亦趋地模仿跟踪现有本科院校模式,其新的职能和定位是应用型工程本科教育.如何开展应用型工程教育,这是新建工科院校一直努力探讨和实践的课题.本文结合黑龙江工程学院的办学实践,对应用型工程教育问题作一点粗浅的探讨. 相似文献

Totally negative results of epidemiological investigation of random samples do not prove the absence of the infection as the pathogen may be restricted to only a few animals in the herd for a long time. The statement "absence of infection" is critical for such situations. The question is raised, whether the statement "absence of infection" should be generally avoided. Classification of herds and flocks according to the prevalence of the pathogen would be more valid for the implementation of control measures. 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

Employed 120 male and 113 female undergraduates in a replication of H. L. Mirels's (see record 1970-10386-001) study which found 2 factors in analyzing responses to 23 items on Rotter's Internal-External Control Scale. The same polar dimensions of "luck" as the arbiter of life events as opposed to personal control were found as well as a 2nd dimension of degree of control over political and social institutions.
