我是一位教了25年中学生物的教师。在2006年“安徽省科技馆杯”第二届全省中小学教师科学实验创新大赛中,我以一个物理创新实验获大赛的二等奖。获奖以后,很多人都感到奇怪,教生物的怎么搞起了物理实验,而且在众多专业物理人士当中脱颖而出,获得二等奖?更令人感到奇怪的是我的实验内容“磁铁的同极相吸、异极相斥”,严重违背了教科书中的“同极相斥、异极相吸”的观点,大有反科学的嫌疑。这到底是怎么回事?我是怎样发现和解决这一问题的呢?
I am a teacher who taught biology for 25 years. In the second session of the Provincial Primary and Secondary School Teachers’ Scientific Experiments and Innovation Competition of the “Anhui Science and Technology Museum Cup” in 2006, I won the second prize of the competition with a physics innovation experiment. After winning the award, many people were surprised to learn how to teach physics how to teach physics, and to stand out among many professional physicists and win the second prize. What’s even more surprising is that my experiment content is “the same phase of the magnet.” “Sucking and repulsion” has seriously violated the point of view of “reprove each other in the same pole and attract each other” in textbooks, and has a lot of anti-science suspicions. What’s going on here? How did I find and solve this problem?
