初中生物新课程旨在提高学生的科学素养,为学生终身学习奠定基础。这就要求新课程背景下的生物教师必须优化课堂教学模式,打造以学生主动参与、师生双向互动为主的高效课堂教学模式。笔者结合多年的教学实践,形成了“预习—探究—展示—反馈—生成”五个环节的课堂教学模式,大大提高了课堂教学的有效性。“五环节”教学模式以初中生物新课程标准为依据,运用了建构主义理论、生成性学习理论和现代教
The new junior high school biology curriculum aims to improve students ’scientific literacy and lay the foundation for students’ lifelong learning. This requires that the biology teacher under the new curriculum must optimize the classroom teaching mode and create an efficient classroom teaching mode that takes students’ active participation and the two-way interaction between teachers and students. The author combines many years of teaching practice, formed a “preview - explore - show - feedback - generate ” five aspects of classroom teaching mode, greatly improving the effectiveness of classroom teaching. “Five links ” teaching model to junior high school biology curriculum standards as the basis, the use of constructivism theory, generative learning theory and modern teaching
