鳥类的干制     

Г.А.古里雅諾夫  罗润庠 《生物学教学》1959,(7)

在生物学課堂教学中,直观教具的演示,是教学和教育工作中不可缺少的一部分。但生物教师却不能每一堂都能安排好必要的教具。这是由于教师不会自己制备教具的緣故。我从事各种直观教具,特别是对爬行类、鳥类与哺乳类动物的干制标本,已有十余年的經驗。本文將介紹应用40%的福尔馬林溶液注射于动物屍体的方法干制鳥类标本的经验。剥制法虽比干制法效果好一些,但时間需要较长;此外,剥制时所用的砒霜或砷酸钠这些毒物,往往有危險,而且这些毒物又不易买到。干制只需用福尔馬林,危險性少,而每个藥房也都可买到。干制不同于剝制,以后会干縮变小,但形狀颜色不变。在一定的保存条件(玻璃柜中)下和适当的保养(每一年撒上一层萘粉、六六六药剂等),干制标  相似文献   

对医预科学校学习目标的建议     

Miles J. Schwartz!英  王卫国  梅人朗 《复旦教育论坛》2000,(1)

最近，美国医学院校协会（ＡＡＭＣ）发表了医学院校学习目标报告（ＭＳＯＰ）以协助各院校培养“能够满足社会需求”的新一代医生。两份ＭＳＯＰ报告总体上是鼓励开发医预科学校的学习目标，建立这种学习目标能确保这些未来的医学生较好地面对医学院校的课程，这些课程已经限定了他们在四年中所学的内容。那些不能在标准医学课程中扩展的教育要素能在本科生教育中予以提供，医预科教育也能包含这些内容，例如：通讯技能，写作和演讲；医学的心理社会方面内容，从伦理学到医患关系的延伸；统计学，包括介绍以证据为基础的医学的概论；信息学…  相似文献

Developmental links of very early phonological and language skills to second grade reading outcomes: strong to accuracy but only minor to fluency     

Puolakanaho A  Ahonen T  Aro M  Eklund K  Leppänen PH  Poikkeus AM  Tolvanen A  Torppa M  Lyytinen H 《Journal of learning disabilities》2008,41(4):353-370

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献   

The development of the ability to recognize the meaning of iconic signs     

Tolar TD  Lederberg AR  Gokhale S  Tomasello M 《Journal of deaf studies and deaf education》2008,13(2):225-240

Early developmental psychologists viewed iconic representation as cognitively less complex than other forms of symbolic thought. It is therefore surprising that iconic signs are not acquired more easily than arbitrary signs by young language learners. One explanation is that children younger than 3 years have difficulty interpreting iconicity. The current study assessed hearing children's ability to interpret the meaning of iconic signs. Sixty-six 2.5- to 5-year-olds who had no previous exposure to signs were required to match iconic signs to pictures of referents. Whereas few of the 2.5-year-olds recognized the meaning of the iconic signs consistently, more than half of the 3.0-year-olds and most of 3.5-year-olds performed above chance. Thus, the ability to recognize the meaning of iconic signs gradually develops during the preschool years. Implications of these findings for sign language development, receptive signed vocabulary tests, and the development of the ability to interpret iconic symbols are discussed.  相似文献   

Recognition of facial emotions among maltreated children with high rates of post-traumatic stress disorder     

Masten CL  Guyer AE  Hodgdon HB  McClure EB  Charney DS  Ernst M  Kaufman J  Pine DS  Monk CS 《Child abuse & neglect》2008,32(1):139-153

OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis.  相似文献
