教师应注意教学环节中的任何一个细微的变化和偶然的发现,自主探究就是要让学生从实验中发现问题,捕捉细节。偶然发现意味着知识探究的开始,潜藏着科学奥秘的神奇。一束鲜花、一个苹果、一个不经意的细节,都有可能给科学研究带来惊人的发现和超乎想象的价值。一次偶然的机会可能会孕育一个重大的发现。那是发生在三百多年前的一个真实的故事。英国著名物理学家、化学家罗伯特·波义耳平素非常喜欢鲜花,经常在自己的房间里摆放几个花瓶,要求园丁每次送来几束鲜花
Teachers should pay attention to any minor changes in the teaching and accidental discovery, self-exploration is to allow students to discover problems from the experiment, to capture the details. Accidental discovery means the beginning of knowledge exploration, the mystery hidden in the mysteries of science. A bouquet of flowers, an apple, and an inadvertent detail are all likely to bring astounding discoveries and unimaginable values to scientific research. An accidental chance may give birth to a major discovery. That’s a true story that happened over 300 years ago. The famous British physicist and chemist Robert Boyle, who likes flowers very often, often places several vases in his own room, asking gardeners to send several flowers at a time
