<正>在当前的人体解剖学教学改革中,许多医学院校在不断地探索各种各样的课堂和课外教学模式对解剖学学习的促进作用~([1])。在此大环境下,本校人体解剖学教研室也积极对此课程的教学模式的转变进行了探索。于2017年6月组织并实施了"首届解剖学标本制作大赛",大赛的最初设计理念是针对本校医学生人体解剖学课堂教学以外,开放实验形式单一、缺乏提高学生实践操作能力的有效措施等问题而提出来的,目的在于通过培训学生制作系统解剖学各类示教标本,以应用于学生课前预习、课堂学习和课后复习等教学环节。培训结束后组织解剖学标本制作大赛,秉着以赛代训, 相似文献

<正>人体解剖学是新生入学首先接触的医学专业基础课程,结构复杂,名词繁多,需要记忆的内容较多,学生经常会觉得枯燥难学,这就需要教师从教学模式、教学方法、教学理念等方面开展解剖学课程改革,根据授课内容运用多种教学手段,身体示范、口诀、3DBody多媒体技术~([1])、启发式提问、CBL(案例教学法)、PBL、TBL、思维导图、数字虚拟人体平台、翻转课堂~([2])等,优化教学设计,创设有效的教与学系统的 相似文献

<正>基于问题为基础教学方法(problem based learning,PBL),在培养学生学习积极性、探索能力、解决问题能力等方面显示出独特优势~([1])。微课具有内容简洁、生动有趣味、可重复等优点~([2])。为了能优化教学资源,达到提高教学效果的目的,我们尝试将微课与PBL 2种教学方法有机融合进行局部解剖学教学,并对教学效果进行探索。 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.
