数控线切割加工开放实验需要多层次发展

在数控电火花线切割加工的开放性教学实践中，我们将开放实验分类为：兴趣型认识实验、求知型自主实验和创新型专业实验等层次，取得了一点教学成果。由此，意识到在实验教学中既应该重视素质教育的普遍含义，同时也决不能忽视其中蕴育着的更深层次的发展性、建设性含义。本文先就兴趣型认识实验和求知型自主实验，简略谈一谈它在整个开放实验体系中所处的位置及其重要性。     

开设力学中工程性前沿性的综合实验

本文论述了实验教学改革面临的新问题：如何将实验室最先进的设备、最前沿的科技成果引入本科生教学，开出高水平的、适合学生动手操作的设计型研究型开放实验，将书本知识与工程实际有机结合。我们以科研成果为基础，在国内率先建立了基于残余应力问题的实验平台，开出了“残余应力测定实验”及“弹塑性应力及电测法综合实验”等不同层次的系列实验，首次尝试了高档贵重设备的开放实验形式。应用多媒体教学手段，把大量的工程实际问题拍摄制作成实验多媒体课件，既扩展学生眼界，又适用于开放实验，收到良好效果。     

数控线切割加工的开放实验

在求知型自主性开放实验的基础上，将数控线切割实验提高到创新型开发性实验的层次。并由此认识到优化教学实验内容、使开放实验多层次发展、根据具体条件和具体情况提高实验水平是巩固和发展开放性实验这一实验教学手段的必要措施。     

工程机械开放式虚拟仿真实验教学管理平台建设

基于开放共享的理念构建了工程机械开放式虚拟仿真实验教学平台。该平台集成了6个实验系统,能够循序渐进地开展验证型—设计型—综合型—创新型实验,全面实现技术体系、实验功能、实验内容、实验场所的开放。阐述了平台的建设内容、体系结构,以工程机械原理虚拟仿真系统为例,分析了平台的功能实现。着重论述了平台的开放模式,以及基于这一模式开展的线上线下混合教学模式改革的实践。     

数控线切割加工开放实验的综合发展

微小型模具的研制活动使数控线切割开放实验拓宽了向培养研究型人才、综合型人才发展的空间，证实了在当前素质教育和实验教学改革中致力于使开放式实验向多层次发展的迫切性和重要意义。     

“通信原理”实验开放改革与实践

本文针对传统的实验组织管理，实验模式等方面的不足，阐明了开放实验的必要性与改革构想，介绍了我院“通信原理”实验开放的改革管理措施及开放实验的实施过程与效果。     

开放实验与提高高职学生实践能力的探讨

实行开放实验是提高学生实践能力的重要手段，在实施开放实验时，必须构建实验体系，合理选择实验内容，确定开放形式。要达到开放实验效果，一些必要的配套措施是必不可少的，这样，实行开放实验才能达到培养学生实践能力的目的。     

高职化工专业开放实验的研究与实践

实行开放实验是提高学生实践能力的重要手段，在实施开放实验时，必须构建新的实验体系，合理选择实验内容，确定开放形式。要达到开放实验效果，一些必要的配套措施是必不可少的。     

构建实验室开放平台,培养实用型预防医学人才

我们本着"面向全体、形式多样、因材施教、讲求实效"的原则,开展了多种形式的实验室开放,如综合性和设计性实验、学生参与教师科研活动型实验、学生科技活动型实验、校外实训基地实践、专题实习型实验、能力培养型实验等.实践证明,实验室开放体现了学生的主体地位,培养了学生潜在的创新意识,提高了学生的动手能力.通过参加多种实验及社会实践活动,学生的组织能力、协调能力、交流能力、吃苦耐劳精神及社会责任感得以提高,具备了一定的现场调查与突发公共卫生事件处置能力.     

关于实施开放实验的思考

开放实验是本科教育实验教学的组成部分，在培养学生实践能力，创新能力等方面具有重要作用。本文结合实施开放实验的经验和体会，详细阐述了实施开放实验的效果，分析实施过程中存在的问题，并提出相应的建议。

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?     

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.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
