古人云:“小疑则小进,大疑则大进。疑者,觉悟之机也,一番觉悟一番长进。”实践证明,课堂上让学生大胆质疑问难,能使学生处于兴奋状态,思维被激活,学习积极性不断高涨,变被动学习为主动进取。因此,课堂教学就应重视“以疑为线索,以思为核心”的教学方式,使之从有疑到无疑,再产生新疑,进而培养学生的创新能力。 The ancients said: “The small suspicion is small, big suspicion is big. Suspects, the realization of the machine also, some enlightenment some grow.” Practice has proved that students in the classroom boldly challenged the question, make the students in an excited state , Thinking is activated, learning enthusiasm is constantly rising, changing passive learning to take the initiative. Therefore, the classroom teaching should pay attention to “suspecting the clue as the core,” teaching methods, so that from doubt to doubtlessness, and then generate new doubts, thus cultivating students’ innovative ability.
