设计性电视实验的若干探索

电视技术课程是电类专业学生的重要专业课程,电视实验则是电视技术课程的必不可少的组成部分,作为一门专业课实验,除了开设验证性实验之外,还开设了相当份量的设计性实验。设计是技术的关键,通过设计实验活动掌握技术,培养创新技术型人才日益受到重视,也是当前实验教学的重要改革方向。本文在总结多年从事设计性电视实验教学的基础上,拟就设计性电视实验的开设原则、实施方案、以及考核评估等问题做出若干探索,以求较好地解决设计实验中的问题。     

立新意,促教改,争高质量——工科数学(一)的期末考试与复习

数学科考试旨在考核学生对“三基”(基础知识、基本技能、基本方法)掌握的情况,以及是否具备四种数学能力(运算能力、逻辑思维能力、空间想象能力以及运用所学数学知识和方法分析、解决问题的能力)。电视中专数学期末全省统一考试,既是对学生数学学习的目标参照性考试,也是对各级电视中专及教学点阶段教学质量的检查与验收,客观上是一次全省性会考。因此,期末考试命题的优劣,关系到电视中专的教学质量、电视中专的教学导向、电视中专的声誉和发展。为了搞好期末考试,重要的一环是努力实现考试命题科学化、规     

电视摄像技术与艺术实验课程教学方法探究

电视摄像技术与艺术实验课程,是学生在初步掌握电视摄像理论的基础上,通过实践进一步学习摄像知识、掌握摄像技能的核心课程。本文结合所在学院实验教学的实际,提出了理论与实践相结合、示范演示、任务驱动、讨论交流与合作学习的电视摄像技术与艺术实验课程的教学方法。     

CATV模拟故障实验研究

根据系统维修经给，设计一套模拟有线电视线路故障的实验方法。通过对CATV线路常见故障的模拟，让学生观察电视画面表现特征，并阐述原理，指出易发位置与维修方法，对于培养学生快捷维修能力，效果显著。该实验具有简单、经济、直观、实用等优点。     

电视暴露对幼儿身心发展的消极影响

较长时间的电视暴露对幼儿注意力、幼儿语言能力的形成与发展、幼儿执行能力、幼儿睡眠、幼儿体重和血压状况等均会产生消极影响.电视暴露之所以会对幼儿的身心发展产生消极影响,是因为较长时间的电视暴露会对幼儿的大脑造成过度的刺激,会引起幼儿注意力的分散,会导致亲子互动活动的减少.为此,建议父母亲应限制幼儿看电视的时间,不应把电视放在幼儿的卧室,应陪伴幼儿一起看电视,应避免幼儿在看电视时同时从事其他活动.     

运用电教手段辅助生物实验教学

实验,在生物教学中占有重要地位。近两年来,我运用电视录像教学片进行实验教学,取得了较为满意的效果。它的优点主要有以下几点: 一、借助电视录像能使实验教学简洁明了,重点突出。电视图象可见度大、清晰、色彩鲜艳,可以向学生提供大量的感性材料,便于在短时间内使学生看清实验目的、用具、主要操作步骤和实验技巧。例如“植物细胞有丝分裂”实验,用电视录像首先介绍实验前对洋葱根尖的培养方法。接着放操作过程,包括取材、对材料的处理和盖玻片的使用等。对重点的地方(取材、盖玻片使用)重放一两次,以加深学生的印象。这样在几分钟内就能使全体同学初步了解这个实验的全过程。     

新谋程背景下《科学》实验教学中应强化的几个关系

一、强化实验探究活动与学生知识、能力结构的关系 笔者在用新课标教学理念进行教学实践时,深深体会到:在孩子们阅读能力、计算机知识、上网能力等方面大幅度积累和提升的同时,由于娱乐消遣(如电视)无形中取消了孩子们接触、认识自然界的时间和渠道,而应试教育又挤占了孩子们生活自理和劳动的机会,导致他们对自然界的认识十分肤浅,动手能力十分低下.     

电视原创节目中文化创意的运用策划

电视文化产业离不开文化创意,电视原创节目尤其如此,当今,我国电视竞争虽然已经从节目竞争逐渐转变为频道竞争,但是电视节目仍然是电视频道竞争力的集中体现,其中,电视原创节目是最能够考量一个电视频道节目制作能力以及文化创意能力的。本文就文化创意与电视原创节目相关问题展开讨论,着重分析了文化创意对电视原创节目以及电视品牌塑造的重要性,并提出了相应的对策建议。     

关于高校强化对“准电视摄像师”培养的思考

高校肩负着为社会发展提供合格的电视摄像师的责任,这也是电视事业健康发展的必然要求。本文从强化思想政治与职业道德、培养动手能力与实际操作能力以及培养创新能力与创新精神等方面提出了高校对"准电视摄像师"的培养策略。     

高校电视制作专业实验设备的技术变革

电视制作设备数字化是当前我国广播电视行业的发展趋势.高校电视制作专业实验技术也正从"模拟"过渡到"数字"时期,专业教师应该充分认识这类实验设备技术发展的必然性,掌握好数字化专业实验设备所带来的新技能,以发展的眼光看数字新技术,充实和拓展电视制作实验设备所蕴涵的新知识.     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Social and Cultural Influence on Word Meaning

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

汉字倒说

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。
