科艺小实验中材料的投放与幼儿的兴趣及操作有着密切的相互作用。材料投放的好,投放的巧,能激发幼儿的探索欲望,满足幼儿兴趣的材料能促进幼儿思考,提高实验的成功率。那么中班上学期如何更加有效地开展这类活动呢?通过实践探索和案例分析,我们深深体会到只有提供符合幼儿身心发展特征和认知规律且富有趣味性的材料,科学小实验活动才能开展得有声有色。 The small experiments in science and technology materials and children’s interest in the operation and operation have a close interaction. Materials put good, put ingenuity, can stimulate young children’s exploration desire to meet the children’s interest in materials to promote children’s thinking, improve the success rate of the experiment. So how to carry out such activities more effectively in the first semester? Through practical exploration and case studies, we deeply understand that only by providing interesting materials that conform to the characteristics of children’s physical and mental development and cognition, can science experiment activities To carry out impressive.
