在新课改背景下,教师在教学中需要改变传统教学观念,摒弃传统教学中的确定,在教学中运用多种教学策略进行教学,引入现代信息技术,丰富教学课,在课堂中激发学生的学习动机,提高课堂教学效率,构建高效课堂。在传统高中生物教学模式中,教师教学方法单一,在课堂中以教师的教为教学主题,限制了学生思维能力的发展,学生在学习过程中思维得不到到发展,导致学生在遇到新题型时,没有足够的应变能力,故教师在教学过程中要注重培养学生的解题思维并运用合理的教学策略提高课堂教学效率。本文便以高中生物知识与化学知识相结合为例浅略讲述教师在高中生物教学过程中应如何构建高效课堂,提高教学效率。 相似文献

Joseph Rotblat was born in Warsaw in 1908. He trained in nuclear physics and later specialized in radiation biology. He was awarded the Nobel Peace Prize in 1995, with the Pugwash Conferences on Science and World Affairs, "for their efforts to diminish the part played by nuclear arms in international politics and in the longer run to eliminate such arms." In this essay, he reflects on his experiences and recounts how he has applied his ethical principles to his work as a scientist and educator in Poland, the United Kingdom, and the world. He urges other scientists to apply ethical considerations for the survival of humankind above all others. 相似文献

Academician Yuan Longping, father of hybrid rice, was lately awarded the Magsaysay Prize named after the third Philippine president Ramon F. Magsaysay. The Prize was founded in 1957 which has been known as “the Nobel Prize of Asia”. Prof Yuan received the honor for his great ontributions to hybrid rice research and Asian food security. Hybrid rice yielded about 0.4 billion ton in the past twenty years in Chiha, and has been introduced into 20 countries in Asia, Afica and America and successfully popularized in India and Viemam on a large scale, signifing a great scientific creation in solving the problem of world grain shortage. The awarding ceremony was held on Aug. 31, 2001 in Manila, Phillippines. 相似文献

The Research News article by Faye Flam about the 1993 physics Nobel Prize ("A prize for patient listening," 22 Oct., p. 507), awarded to Joseph Taylor and Russell Hulse for the discovery of a binary pulsar, incorrectly attributed key observations. The measurements implying that the pulsar is emitting gravitational waves were made by Taylor in collaboration with Joel Weisberg, Lee Fowler, and Peter McCulloch, not by Taylor and Hulse. 相似文献

This year's Nobel Prize in chemistry was awarded to a trio of researchers--Alan Heeger of the University of California, Santa Barbara; Alan MacDiarmid of the University of Pennsylvania in Philadelphia; and Hideki Shirakawa of the University of Tsukuba in Japan--for discovering that plastics can be made electrically conductive. The discovery paved the way for revolutionary applications such as full-color displays for cellular phones and plastic electronics for computerized merchandise. 相似文献

Just a few weeks after two physicists won the Nobel Prize for figuring out how to make lasers out of semiconductors, researchers announced that they have made those lasers much more useful. A new technique permits the lasers to shine light in regions of the infrared spectrum previously inaccessible to similar devices. The advance may open the door to cheap devices to sniff explosives and other robotic sensors. 相似文献
