高频逆变焊接电源教学实验平台

针对高校焊接类专业缺少逆变焊接电源实验平台与相关实践课程的现状,以培养"新工科"人才为出发点,设计了用于教学实验的高频逆变焊接电源平台。实验平台主要由主电路和控制检测电路两部分组成,其中主电路包括整流滤波Ⅰ、逆变模块、变压电路、整流滤波Ⅱ、电弧焊枪等模块,控制检测电路包括人机交互系统、主控制电路、IGBT驱动电路、电压电流信号安全监测点等模块。通过问卷调查和成绩分析方式对实践效果进行了评估,结果表明该平台有助于学生充分理解基础理论知识,培养学生的动手创新能力和科研素质。     

“对分课堂”教学模式在“测控电路”教学实践中的运用

课堂教学改革是新工科建设中提高人才培养质量的重要一环,"对分课堂"是一种新的教学模式,将"对分课堂"教学模式应用于"测控电路"课程教学实践,增加了学生之间和学生与老师之间的互动与交流,增强了学生的学习主动性,提升了学生的学习能力。实践表明,通过课堂讲授、内化吸收、课堂讨论三个环节,结合网络教学平台讨论区以及播客单元和作业等环节,学习的自主权真正还给了学生,学习效果得到提高。

语文教学中培养学生创新能力初探

在语文教学中如何培养学生创新能力,本文就此问题从"引新"、"质疑"、"解疑"、"归纳"、"实践""创新"六个方面作了论述。     

电路实验中“实验先于理论”教学改革与探索

以培养学生的自主学习及自主创新能力为目标,对电路实验课程进行层次化、阶梯式的电路实验内容改革,选择部分实验的实验方式进行了"实验先于理论"的自主测试归纳教学模式创新性改革,相应的电路课程教学组织形式采用翻转课堂模式。学生普遍反应对相关理论的理解更为深刻,增强了学生用科学实验方法进行"探索求证"的兴趣和能力,教学效果有了明显的提高。     

《电力电子技术》一体化教学的探索

理论教学和实践教学的是相互促进的,在高职专业教学中实施"理论与实践一体化"教学模式,是加强学生职业素质培养,提高学生综合职业能力的一项重要教学改革。本文结合职业教育的实际情况,进行理论实践一体化教学法的实践,阐述了理论上结合波形图分析电路,实践上测量真实的电路波形,对比理论分析波形加深学生对电路的理解的专业教学改革思路。     

在基础电路教学中培养学生综合能力的思考

针对高职院校教育中存在理论与实践不并重的问题,为强化学生实践能力,培养学生创新思维,对大学生基础电路教学的指导策略进行了探索和思考,并以1个音响放大器设计实验为例,归纳在设计实验中带动学生理解和互动的教学方法,以动带学,培养学生的思考能力、分析能力和创新能力等综合能力,使学生能用基本的电路原理知识阐述和解释电路现象,提高学生学习积极性和学习效率。实践证明,在基础电路教学中改变传统的灌输式教学模式,以理论为引导,实践为途径,主导学生自主设计和提出问题,在实验中穿插不同手段的教学和引导方式,让学生学会观察、评价以及提出和解决问题,是课堂教学发展新方向。     

如何培养小学生学习英语的能力

<新课程标准>以描述学生"能做什么"为主线,强调学生要能用所学的英语做事情.要通过创设良好的语言环境和提供大量的语言实践的机会,使学生通过自己的体验、感知、实践、参与和交流,形成语感;在教师的引导下,通过观察、发现和归纳等方式,掌握语言的规律,形成有效的学习策略,通过交流与合作发展交流与合作的能力.     

基于“类”的小学语文归纳教学研究——以三年级中国民间故事单元为例

传统的语文教学以演绎教学为主,演绎教学更强调知识的传递性、结论性以及掌握知识的精熟程度。而归纳教学则强调让学生经历一个完整的过程,学习过程是学生发现知识、获得知识的过程,更关注学生的经验、学习的起点、存在的差异。立足于语文课程与教学实践改革中的单元,剖析基于"类"的语文归纳教学的意义与价值;从实践层面回应基于"类"的语文归纳教学的实践样态。     

动态电路的简化与解析

通过对静态电路和动态电路的特点及区别的分析与归纳,让学生掌握动态电路的简化方法,从而达到让学生能够对复杂的动态电路和静态电路轻松解析的目的,进而提高学生的分析问题和解决问题的能力。

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?     

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.     

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.
