在教学过程中,以"科氏力实验系统"为教学案例,提出了一种课堂教学、实验探索与自主学习相结合的教学模式.在该教学模式下,使得学生在学习中实践,在实践中学习,逐步学会主动驾驭知识,提高综合应用所学知识解决实际问题的能力.  相似文献

现代经济学与自然科学有相似的演进逻辑与检验模式。经济学理论从简单到复杂,呈现出累积式进展且不断深化;经济学的科学性体现为理论体系的经验性与可反驳性,经验资料对理论的反驳是经济理论演化的根本动力。深刻理解这一问题,对中国经济学的发展具有重要的现实意义。  相似文献

The speed of high-resolution optical imaging has been a rate-limiting factor for meso-scale mapping of brain structures and functional circuits, which is of fundamental importance for neuroscience research. Here, we describe a new microscopy method of Volumetric Imaging with Synchronized on-the-fly-scan and Readout (VISoR) for high-throughput, high-quality brain mapping. Combining synchronized scanning beam illumination and oblique imaging over cleared tissue sections in smooth motion, the VISoR system effectively eliminates motion blur to obtain undistorted images. By continuously imaging moving samples without stopping, the system achieves high-speed 3D image acquisition of an entire mouse brain within 1.5 hours, at a resolution capable of visualizing synaptic spines. A pipeline is developed for sample preparation, imaging, 3D image reconstruction and quantification. Our approach is compatible with immunofluorescence methods, enabling flexible cell-type specific brain mapping and is readily scalable for large biological samples such as primate brains. Using this system, we examined behaviorally relevant whole-brain neuronal activation in 16 c-Fos-shEGFP mice under resting or forced swimming conditions. Our results indicate the involvement of multiple subcortical areas in stress response. Intriguingly, neuronal activation in these areas exhibits striking individual variability among different animals, suggesting the necessity of sufficient cohort size for such studies.  相似文献

OBJECTIVE: The objectives were to estimate the prevalence and correlates of physical abuse-related outcomes in the family setting in Hong Kong's adolescent population. METHOD: A cross-sectional study design was used. A randomly selected sample of 3,355 secondary school students in Kwai Tsing District of Hong Kong was surveyed. The response rate was 98%. RESULTS: The prevalence rates of corporal punishment, being beaten by parents for no apparent reason, being beaten to injury by family members in the past 3 months and any one of the above three were 4.9% (95% CI, 4.2% to 5.6%), 2.0% (95% CI, 1.5% to 2.5%), 1.1% (95% CI, .98% to 1.2%) and 6.6% (95% CI, 5.7% to 7.5%), respectively. Students who had experienced the above physical abuse-related outcomes were at a significant disadvantage for a wide range of morbidity indicators, including self-perceived bad health, anxiety and stress, somatic illnesses (such as asthma and epigastric pain), injuries and accidents, and hospitalization. They were more likely to have poor familial relations and coping skills, and to take up habits which potentially put their health at risk, such as smoking, alcohol consumption, and fighting with others. CONCLUSIONS: Our prevalence estimates of physical abuse in the family setting for a student population in Hong Kong is an improvement over previous local estimates of physical abuse occurrence, which were mainly based on case notifications and clinical samples. The results also show that the abused adolescents are growing up in an environment filled with physical, psychological, and familial adversities.  相似文献

“楼”是有着重要文化意味的“符号”,它的出现常常预示着一个朝代的兴亡。“楼”作为建筑,是古人突破限制,扩大视野,接近宇宙的现世渴望的表达,从某种意义上说,“楼”,是山的替代物。因此“登楼”便隐含着“登山”的信息。由于“楼”的建设需要大量的人力、物力,诗人登楼不可能如同后世来的自然和方便。这就使得诗歌中的“楼”,最先是“观”而非“登”的。如此,可观的高楼,通常成为诗人对于可望而难达的愿望的替代表达。  相似文献

关于理工科大学加强人文素质教育的思考   总被引:13,自引:0,他引:13  
长期以来,我国理工科大学过分重视大学生的业务学习而忽视人文素质的现象比较突出,带来学生文化素质较缺乏,社会适应能力较低等负面效应。因而要转变教育观念,优化资源配置,为人文素质教育提供优良的外部环境;改革和更新教育方法和教育思维,使人文知识浸润于专业知识之中,人文教育内化为学生的人文精神。科学化的人文教育和人文化的教学教育的有机结合,是新世纪理工科大学人文教育的发展方向。  相似文献

意识是具有意识信息的脑神经细胞活动的结果,是后天形成的具有意识信息的脑神经细胞在活动过程中所释放出来的信息。人的部分脑神经细胞具有在内外刺激下复合新物质以储存信息的功能。意识的形成机制是:在内外部刺激的作用下,人体的感受器把刺激信息转换成相应的电信号,传递到脑神经细胞,使细胞发生相应的生化反应,形成新的储存相应信息的意识细胞,当这些新的意识细胞再次受到激活时,便会释放所储存的信息,从而产生意识。  相似文献

This article describes the development of an instrument – the Career and Talent Development Self‐Efficacy Scale (CTD‐SES) – for assessing students’ self‐efficacy in applying life skills essential for personal talent development, acquisition of positive work habits, and career exploration. In Study 1, data were obtained from a large sample of Chinese middle‐school students (N=15,113) in Grades 7–9 in Hong Kong. The CTD‐SES is an 18‐item questionnaire with subscales containing items that address students’ orientations toward developing their own talents, acquiring and applying positive work habits, and exploring their career possibilities. Evidence is provided for internal consistency, temporal stability, and factor structure of the CTD‐SES. Goodness of fit statistics provided support for a three‐primary‐factor‐plus‐higher‐factor model, and this solution was used in the statistical analyses. The data also indicated that students with plans for university study reported significantly higher scores than those without on all three domains of career and talent development. In Study 2 (N=308) Grade 10 high‐ability students’ scores in CTD‐SES were correlated with scores in career decision self‐efficacy and academic performance. The development and validation of CTD‐SES is the first step toward investigating career exploration, work habits, and talent development among Asian middle‐school adolescents.  相似文献
