人体解剖学是医学生进入医学院校后首先接触的医学基础课程,该课程的特点为实践性和操作性强,实验课学时多,实验教学环节对培育学生创新意识和创新能力起到重大作用,为此,已受到越来越多同仁的关注,并对之进行着改革研究。近年来,我们针对三年制临床医学专科学生的实际情况及岗位需求特点,在遵循解剖学实验教学固有规律的基础上,就解剖学实验教学目标定位、实验内容构建、教学方法及手段改革、实验教学质量评价等方面展开探索和实践,以供同行参考、探讨。 相似文献

解剖学实验教学改革的探索与研究 总被引:1,自引:0,他引:1
人体解剖学是一门重要的医学基础课程,属形态学范畴。解剖学实验作为解剖学教学的重要组成部分,是学生对人体结构获得感性认识的重要手段,长期以来,由于受传统教学理念的影响,解剖学实验教学只注重教师的主导作用,忽视了学生应用能力的培养,严重影响了学生学习的积极性、主动性和创造性。因此,适应现代医学教育的需要,转变教学观念,加强解剖学实验教学改革,以培养实用型医学人才,是一个亟待解决的课题。1转变实验教学理念,加强学生素质教育解剖学是临床学科和医学其它基础学科的基础课程,是医学生认识人体的开始,解剖学实验具有较强的实践性… 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.
