首先,是角色扮演能调动学生学习的主动性和积极性。在《生物圈》这一节教学中,一次是让学生分别扮演生物的居住环境:水圈、大气圈和岩石圈,边表演边说出这三个圈层中都有哪些生物在生活;另一次是让学生明白地球上生物生存所需要的基本条件是一样的,都需要营养物质、阳光、空气、水,还有适宜的温度和一定的生存空间。学生扮演两种生物:不幸落到金星上的含羞草和落到火星上的小白兔。学生发挥想象力和创造力,以反证地球生物圈对生物的生存何等重要。
First of all, it is role play that can mobilize the initiative and enthusiasm of students. In the teaching of “Biosphere”, the first is to let the students play biological living environment: water circle, atmosphere and lithosphere respectively. While performing, they will say which creatures in the three circles are living. Another It is for students to understand that the basic conditions needed for living on Earth are the same. All require nutrients, sunshine, air, water, proper temperature and certain living space. Students play two creatures: the mimosa that unfortunately fell on Venus and the little white rabbit that fell on Mars. Students exert their imagination and creativity to justify the vital importance of living organisms in the Earth’s biosphere.
