范例是在繁杂的知识中选出的代表,在其启发、引导和帮助下,激发学生的兴趣,帮助学生了解知识的本质及内在的规律.在初中化学的教学中,教师结合教学内容和学生实际,灵活的建立扩展性、迁移性、开放性、激励性的范例,使学生可以从多角度来了解概念,深入探究其中的化学规律,提供相互合作学习的平台,实现学生的思维突破和创新.在范例的指引下,使教学清晰、简洁、主题性强,使学生的思维积极、灵活、创新性强,从而打造教与学相结合的高效课堂.
The paradigm is a representative elected from a complex set of knowledge, which inspires students’ interest and helps students understand the essence and inherent law of knowledge under the inspiration, guidance and help of teachers.In the teaching of junior high school chemistry, teachers combine teaching contents and students Practically and flexibly establish examples of scalability, mobility, openness and motivation so that students can understand concepts from multiple perspectives, explore their chemical laws in depth, provide a platform for mutual cooperation learning, and achieve breakthroughs and innovations in student thinking Under the guidance of the example, the teaching is clear, concise and themed so that the students’ thinking is positive, flexible and innovative, so as to create an effective classroom combining teaching and learning.
