“雨课堂”教学模式在中医学教学中的应用体会

中医学是我国医学高等教育课程中的一个重要必修课,目前传统的教学模式是以教师课堂讲授、演示为主体,学生参与度低,这将对课程的学习效果及学生临床实践能力的提高产生不良影响。文章通过对"雨课堂"混合式教学模式在中医学教学实践中应用现状的分析,剖析当前中医学教学中存在的一些问题,结合"雨课堂"混合式教学模式在教学设计和师生互动上的独特优势,探讨"雨课堂"混合式教学模式对提高学生学习积极性和参与性、培养中医学临床实践能力等方面的促进作用,为中医学课程的综合教学方法的运用提供参考,为制定科学合理的教学管理制度提供依据。     

雨课堂在肾脏内科临床见习教学中的应用评价

目的探讨雨课堂教学方法在本科生肾脏内科临床见习教学中的应用效果。方法38名学生随机分为两组,试验组(n=19)采用雨课堂教学方法,对照组(n=19)采用传统讲授式教学方法,教学结束后评估学生课堂上的表现,并对学生进行成绩考核和教学满意度进行问卷调查。结果试验组学生的课堂表现优于对照组。试验组的考核成绩(94.5±2.81)也明显高于对照组(91.0±2.77)(P<0.05)。调查问卷结果提示试验组学生对教学提高学习主动性、分析问题能力、临床实践能力、课堂气氛活跃度、师生间沟通度的评价均优于对照组。结论雨课堂教学方法克服了传统教学方法的一些缺点,在肾脏内科临床见习教学中有比较好的效果,是一种值得鼓励和推广的临床教学方法。

Study on the Relationship Between Meteorological Conditions and Acid Rain in Mid-Eastern Fujian

Based on the acid rain observation data and the contemporaneous historical synoptic charts of Mid-Eastern Fujian during the period of 1991 to 2003, we analyzed the distribution characteristics of acid rain in different seasons, weather types, precipitation grades and wind directions. The results showed that the acid pollution in Mid-Eastern Fujian was still serious. In winter, the precipitation pH value was 4.79, and the acid rain frequency was 60.62% which was twice higher than that in summer. The pH value of warm shear-type precipitation at 850 hPa was 4.79. Nearly half of these precipitations had the problems of acid rain pollution. The acid rain frequency of the inverted trough type was only 26.11% which was the lowest one in all types. There was no marked difference of the acid rain distribution characteristics between ahead-of-trough and behind-the-trough. The precipitation pH values of the five grades were lower than 5.30 and the acid rain frequency changed as an inverted U shape with the increasing of the rainfall. The pH values of precipitations in the eight wind directions were generally below 5.20, and the acid rain frequencies were about 40%.     

EXTRACTING SMALL IRREGULAR AREAS

Ten fruits were collected at random from each of five parent trees of Eucalyptus delegatensis R.T.Bak. (alpine ash) in each of 18 separate localities in New South Wales and the Australian Capital Territory in 1977. The contents (both seed and chaff) were carefully extracted and the seed examined for insect damage. Seeds destroyed by insects were common. In some individual-tree samples the fraction of seeds destroyed was as high as 81% but the overall mean for all tree samples examined was 20%. Significant differences in the fraction of seeds destroyed were found among localities, and one region, enclosing 3 adjacent localities, had significantly higher numbers of seeds destroyed per fruit than the remaining localities. Two unidentified species of Megastigmus spp. (Hymenoptera: Torymidae) were most commonly associated with seed destruction within fruits.
