苏霍姆林斯基说过:在人的心灵深处,都有一种根深蒂固的需要,这就是希望自己是一个发现者、研究者、探索者。在新课程标准中,对猜想有这样的基本要求:尝试依据已有经验和知识对问题的成因提出假设猜想,对探究的方向和可能出现的实验结果进行推测与想象。教学中积极推行猜想,是培养学生的创新精神和实践能力的重要途径,有助于学生全面掌握知识,并能活跃其思维,开阔其视野,促进学生智力的发展与提高。
Sukhomlinski said: In the depths of human mind, there is a deep-rooted need, which is to hope that he is a discoverer, researcher, explorer. In the new curriculum standard, there is such a basic requirement for conjecture: trying to put forward hypothetical conjecture on the cause of the problem based on the existing experience and knowledge, and speculating on the direction of exploration and possible experimental results. The active promotion of conjecture in teaching is an important way to cultivate the students’ innovative spirit and practical ability, which helps students acquire a complete knowledge of the subject and can stimulate their thinking and broaden their horizons so as to promote their development and improvement.
