对初入校门的新生来说,学好人体解剖学,对后续课程的学习至关重要。如何帮助学生理清学习思路,打好医学基础,培养学生正确的医学逻辑思维方法,无疑成为医学教育工作需要探讨的问题。而解剖教师作为医学生接触到的第一位医学基础课教师,应该肩负起引导学生培养正确的医学逻辑思维方法的责任。常规的人体解剖学教学以老师讲解为主,学生往往认为人体解剖学的学习以背诵为主,并没有认识到人体解剖学知识在医学实践中的重要性。源于西方的教学模式一基于问题的学习(problem based learning,PBL)是在教师指导下,以学生为主体,以问题为基础的小组讨论式教学方法,旨在培养学生逻辑思维能力,提高独立分析问题、解决问题的能力。我们在人体解剖学教学中应用PBL原理,在实习课中穿插进行病例讨论,引导学生学习正确的人体解剖学推理方法,帮助学生培养医学逻辑思维方法,深受学生的欢迎。 相似文献

人体解剖学是研究正常人体形态结构的科学,是学习生理学、病理学和各临床学科的基础课程。解剖学名词多、内容繁杂、逻辑推理少,多以描述性语言为主,在传统的教学方法下,如何活跃课堂气氛、调动并激发学生的学习兴趣,一直是困扰教师的一个难题。为此,作者在2006级护理学本科专业的系统解剖学教学中,对传统的教学方式进行了一些改革性尝试,即结合授课内容,进行了小规模、阶段性的以问题为基础的学习模式(problem-based learning,PBL)的教学实践,收到了良好的效果,但也暴露了一些问题。本文就此次采用PBL教学模式的经验和存在的问题进行了总结。 相似文献

人体解剖学是一门重要的医学基础课程,但是学生在学习这门课程时常常感觉枯燥、难学,以致产生厌学情绪。针对这些情况,如何能调动学生的学习兴趣?我们采用了启发式和PBL教学,努力提高教师的语言素质,恰当而灵活地使用PowerPoint幻灯演示,调动学生学习的主观能动性,使学生牢固地掌握这门课程。 相似文献

A further analysis of already published data supports the position that retardates of low ability level less frequently have retarded siblings, retarded parents, and parents low in occupational level than do retardates higher in ability level. The analysis supports the position that there are two types of retarded individuals, persons retarded as a result of gene or chromosomal anomalies, brain injury, etc., who more frequently occur in the lower-level retardate group, and persons whose retardation represents polygenic segregation, who more frequently occur in the higher-level group. 相似文献

Eighteen families in which both parents had refractions within the range of +4·0 D to −4·0 D and axial lengths seen in emmetropia (22·3-26·0 mm) showed coefficients of correlation of the order 0·5 indicative of polygenic inheritance. Such coefficients were seen for axial length (0·407) and for the cornea (0·487), but not for the lens (which is known to be yoked to the axial length). No such coefficients were seen in 19 families in which one of the parents had axial length outside the emmetropic range (nine families with long axes and 10 with short axes).
The pattern of polygenic inheritance for emmetropia (completely correlated optical components) and errors of refraction up to 4·0 D (inadequately correlated components: correlation ametropia) follows that seen in stature and other measurable characters. In contrast the high refractive errors with their abnormal axial lengths (component ametropia) are—like the extremes in stature—pathological anomalies with monofactorial inheritance.
