多媒体教学与学生心理发展     

程大琥  陈最华 《湖南广播电视大学学报》2006,(2):6-9

多媒体教学已经融入许多学科和学段的课堂教学中,正在对学生的心理发展特别是学习心理发展造成深刻的影响。调查表明,多媒体教学对学生认知心理发展的影响普遍大于非认知心理发展的影响,同时这些影响又存在多方面的非平衡性。应当密切关注多媒体教学的利弊长短,从根本上确立一种指向,正确引导第一线的教学实践。  相似文献

连作烟草根际土壤化感潜力评价及化感物质鉴定     

薛玉萍 《喀什师范学院学报》2012,33(1):46-49,59

以不同植烟年限的烟草根际土壤为材料,设置6个不同浓度的土壤水浸提液处理,分别对莴苣和烟草进行生物测试,同时用2g.mL–1的正已烷、乙酸乙酯、氯仿、丙酮和甲醇5种不同极性有机溶剂根际土壤浸提液进行化感潜力评价;采用气相色谱和质谱联用技术（GC-MS）鉴定烟草根际土壤甲醇浸提液所含的有机化合物。结果表明：（1）烟草根际土壤水浸提液对莴苣和烟草胚根生长的影响表现为低促高抑的双重浓度效应,并且随着种植年限的增加抑制作用增强。（2）浓度为2 g.mL–1的烟草根际土壤甲醇浸提液对莴苣和烟草胚根的生长抑制作用最强,正已烷、氯仿、乙酸乙酯土壤浸提液基本上无抑制现象。（3）鉴定了不同种植年限烟草根际土壤甲醇浸提液中所含的有机化合物,其中种植1年、种植3年的烟草根际土壤甲醇浸提液中存在烷烃、醇、酮、酸、酯、酚、萜烯类以及多环芳烃等有机化合物。  相似文献   

网络教学效果影响因素实证研究——基于社会认知理论及整合性技术接受模型     

常玮  马玲 《远程教育杂志》2012,(1):85-91

在分析网络教学特点、学生、学习风格的基础上,从认知角度出发,采用整合性技术接受模型、社会认知理论等,对国内网络教学效果的影响因素进行研究。通过问卷调研的方法,将学生按照学习风格进行分组,识别出不同学习风格类型的学生对于网络教学效果的显著影响因素,并进一步探讨了适合不同学习风格学生的网络教学策略,对网络教学服务提供者改善网络教学适应性和教学效果具有借鉴作用。  相似文献

施珊珊 《湖北广播电视大学学报》2012,32(11):98-99

本文从行为学和神经认知科学等角度归纳了国内外关于语言认知性别差异的研究。结果表明,无论国外还是国内对语言认知是否存在性别差异这一课题都未得出一致结论。在分析归纳的基础上,本文为国内未来该课题的研究指明了新的方向。  相似文献   

中英数字隐喻     

王应应  林俐 《牡丹江教育学院学报》2012,(5):43-44

自20世纪70年代以来,语言和认知开始结合起来进行研究.认知语言学家认为,人类对世界的认识是通过自身与外部世界互动而产生的.人类通过自身的身体经验来感知现实,研究语言的概念结构和意义,探索语言结构以下深层次的认知方式,并对其作出合理的统一解释.数字除了在科学领域有举足轻重的地位以外,通过数字的隐喻内涵,在认知语言领域也能起到抒情迭意、引起联想的功能.本文主要研究中英文中的数字隐喻现象,进而探讨人类的认知过程.  相似文献   

Emotional design in multimedia learning: Effects of shape and color on affect and learning     

《Learning and Instruction》2014

We examine design factors that may evoke positive emotions in learners and investigate the effects of these positive emotions on learning. Recent research showed that the emotional design of multimedia learning material can induce positive emotions in learners that in turn facilitate comprehension and transfer. We sought to replicate these results with a different population and different mood induction procedure and examine individual emotions, and to decompose the effects of the design elements of color and shape. Study 1 showed that well-designed materials induced positive emotions and facilitated comprehension, though transfer performance was not affected by emotional design. Study 2 found that round face-like shapes both alone and in conjunction with warm color induced positive emotions. Warm colors alone, however, did not affect learners' emotions. Comprehension was facilitated by warm colors and round face-like shapes, independently as well as together. Transfer was facilitated by round face-like shapes when used with neutral colors.  相似文献   

Setting the agenda for environmental news: The effects of media and public characteristics     

Michael B. Salwen 《Communication Research Reports》2013,30(1):52-57

This study examined the relationship between different media agendas and public agendas in the agenda‐setting process. The local and regional media agendas for environmental news in the Lansing, Michigan, area were exactly the same. It was also found that respondents could accurately assess media issue emphasis when they were asked to do so.  相似文献

Mates or Married? Implications of Gender Composition and Physical Intimacy on Evaluation of Images Tested for Advertising     

Glenna L. Read  Isaiah J. Innis  Irene I. van Driel  Robert F. Potter 《Communication Research Reports》2013,30(3):220-230

Drawing upon the theoretical framework of social identity theory and literature on physical intimacy, consumer neuroscience, and social cognitive and affective neuroscience, responses to images featuring same-gender and other-gender pairs are explored through examination of self-reported attitudes and neural activity associated with attention, memory, and emotion. Under the pretense of pretesting the effectiveness of images to be used in a national advertising campaign, participants viewed still images while neuroelectric brain responses were recorded. Each image featured two women, two men, or a man and a woman presented in positions of physical intimacy. Results indicated that event-related brain potentials (ERPs) associated with attention did not differ overall based on couple composition. However, ERPs associated with working memory and emotion were enhanced when processing images with two men. Preference for these images was reflected in self-reported attitudes.  相似文献
