数学需要猜想,数学课堂中的猜想,可以使学生获得发现的机会,发散学生数学思维,提高学生解决问题的能力,缩短解决问题的时间。审视当前数学课堂教学,大部分数学教师只关注数学知识教学,忽视学生数学猜想意识的培养和猜想能力的训练,在课堂上很少给学生猜想的时间和机会。为了学生的可持续发展,教师要转变教学观念,以长远的眼光重视课堂猜想,让猜想点燃学生的探究激情,激活发散思维,获得创新发现。
Mathematics needs to be guessed. The conjecture in mathematics classroom can make students get the chance of discovery, diffuse students’ mathematical thinking, improve their ability of solving problems and shorten the time to solve the problem. Examining the current mathematics classroom teaching, most of the mathematics teachers only focus on the teaching of mathematics knowledge, neglect the cultivation of students’ mathematical conception consciousness and the training of the conjecture ability, and rarely give the students time and opportunities in the classroom. In order to ensure the sustainable development of students, teachers should change their teaching ideas, pay more attention to the classroom conjecture in the long-term perspective, make the conjecture ignite the students’ passion for inquiry, activate the divergent thinking and obtain the innovation discovery.
