牛顿曾经说过:“没有大胆的猜想,就不可能有伟大的发现”.猜想作为一种思维活动,是科学探究的基本前提,是创新发明的动力源泉.物理探索需要经历发现问题、猜想假设、实验验证,得出结论的过程.因此,初中物理教学中,教师要重视猜想手段的运用,优选有效策略,鼓励学生大胆猜想,引导学生敢猜、想猜、乐猜,从而开发学生的智力和想象力,发展学生的思维能力,增强学生的物理探究和创造能力.一、创设猜想情境,激发猜想兴趣 Newton once said: “Without bold conjecture, there can be no great discovery.” Conjecture as a kind of thinking activity is the basic premise of scientific inquiry and the source of power for innovation and invention.Physical exploration needs to go through the process of discovering problems, Hypothesis hypothesis, experimental verification, and conclusion process.Therefore, teachers should pay attention to the use of the means of conjecture in junior high school physics teaching, optimize effective strategies, encourage students to make bold conjecture, and guide students to dare to guess, guess and guess so as to develop students Of intelligence and imagination, the development of students ’thinking skills, enhance students’ physical exploration and creativity.
