演示实验的教学是教学艺术的一部分,出色的讲述不会妨碍演示的进行,巧妙地演示也不是一言不发,演示实验的教学应是讲述与演示有机的、巧妙的结合。现谈谈演示技巧。 相似文献

初中物理演示实验包括实体演示实验和虚拟演示实验两类。教师在初中物理教学中开展演示实验,不仅能够降低物理实验成本,弥补传统实验教学的不足,还有助于激发学生的物理探究兴趣。在开展演示实验时,教师要本着以问题为主线的基本原则,借助问题促进学生思考、探究,同时还要注重现场演示与多媒体辅助视频演示的结合,全面优化演示实验的效果。 相似文献

西方传统哲学对人的思考严格遵循主—客的思维模式,大力弘扬主体性原则,崇尚“人类中心主义”。而自西方现当代人文思潮产生以来,对人的理解发生了转向,弘扬非理性,倡导人与自然的融合。海德格尔就是这种思潮的代表。文章从本体论和认识论两个维度对海氏“人（此在）是澄明”这一哲学命题作出了新的解释。 相似文献

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. 相似文献

Abstract Studies on health pedagogy in medical students in African universities are lacking. The aim of the current investigation was to assess the following pedagogy influences on second year Zimbabwean medical students’ well-being. A group of 100 students studying Physiology and Anatomy in MBChB. II program at the University of Zimbabwe College of Health Sciences were asked to voluntarily complete a structured questionnaire. As Physiology was examinable, students desired to practice MCQ questions. Dissection was regarded as excellent for medical knowledge. The stress of study probably necessitated the drinking of alcohol. Most of the respondents did not actively smoke. Although students knew about calories, they were unaware of the daily requirements. Their diets were mostly balanced. Music helped alleviate stress. Stress levels were high although no overwhelming effects on general health were observed. IT use was rated well although the slow internet was problematic. We encourage more studies on medical students in central and southern Africa. 相似文献

This paper presents the narratives of five creative Irish Adults who contributed to the study by sharing their childhood education experiences. The five participants are all of different ages and occupations. All identify themselves as highly creative people and all worked with me over the course of this study to identify how this creativity developed within their engagement with the Irish childhood education system. All excelled with higher education and they share a high degree of success within their careers. Between them, they express their creativity across five key genres. These are: Science, Engineering, The Arts, Entrepreneurship and Social Entrepreneurship. Well-developed themes were analysed to identify interrelationships which formed a theoretical framework of core concepts that demonstrate what holds great importance in the lives of these participants for the development of their creativity during childhood education in Ireland. A clear theme of this study was that of connectivity. Connections and relationships matter greatly. The creative journey is joyful and clear where children experience a positive connection with their educator. Conversely, the creative journey is stymied by a lack of connection or by a negative connection. These stand in the way of creative growth, like a big boulder on the child's developmental path. This paper showcases, through the stories of these five research participants, how creativity development is affected by the connection between the child and their educator. 相似文献

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. 相似文献

The strabismus conception of masculinity and power with its manipulation as reflected in the consequences of actions endorsed and demonstrated by leaders, followers, citizens as individuals and groups at different times in the past, and present has been a major source of the seemingly quiescence and underdevelopment in Africa. Masculinity has often been associated with being athletic, breadwinner, objective, sexually aggressive, unemotional, dominating, etc.; while power is frequently construed as a tool of dominance, authority, superiority, influence, and governance. This inapt perception was borne out of Africa＇s nictitating and ignorance. The consequences of the misconception include abuse of power, intolerance, intimidation, militancy, humiliation, insecurity, inadequate dialogic tools and opportunities, etc. These result in the Climate of Fear as being experienced in the Niger-Delta of Nigeria, Kenya, and other parts of Africa. Thus, this paper examines the concepts of masculinity and power with exemplification from Africa with Wole Soyinka＇s Climate of Fear. The research methodology employs a combination of critical discourse analysis and Halliday＇s systemic functional theory of grammar with sociolinguistics approaches for the analysis. The study posits that the root of the problems that abound in Africa is traceable to the lack of precise socio-cultural, political and philosophical ideologies by Africans. The research opines that these fundamental problems of Africa can be resolved through orientation with education for all, which is one of the challenges of the millennium development goals. Thus, the paper examines the contrivance of open distance learning and its role in the education of African citizenry. It concludes on the ground that open distance learning as a recent and welcomed information technological development in Africa, if properly channeled and adequately funded would enhance sustainable development in Africa by its elimination of some of the aforementioned obstacles. 相似文献

Rhetoric has claimed Chapman's Coatesville address as its own, but the hermeneutic tradition adds to our understanding of it. As a speech act it was intentionally a non‐event, a memorial for its own failure. This was its strange rhetorical purpose and its claim on a posthumous textual life. In a strange way, it is more a hermeneutic than a rhetorical act, an anticipation of its own future life after death. The open‐ended strategy of the speech is a self‐reflexive enactment. Chapman's Coatesville address is a textual model, illustrating the passage from autobiography to rhetorical engagement, from self to community. Because its community is the nation that as yet has not dealt with its darkest problem, the narrative identity of the speech's audience is an identity in process. Caught up in the reception of the speech, we are still being invited to respond to that lynching at Coatesville. 相似文献

My mother's angry scream broke into the happy,friendly world of Mister Rogers' Neighborhood.Even as a 6-year-old, I often escaped into the neighborhood of the kind, soft-spoken man who wore that brightly colored sweater. But on this day, any attempt to slip into my safe TV world didn't work. My mom's angry shouts made sure of that. 相似文献
