                      【活动评析】

                      幼儿对日常生活中的科学现象和科学问题有着天生的好奇和探究欲望,《有趣的两面镜》就是因幼儿的兴趣生发出来的。(出自:屈老师网)在教学活动中,我先诱发幼儿的认知冲突,鼓励他们大胆提问和猜想。幼儿有了猜想和问题,并产生想寻求答案的愿望,主动探究才会进入真正的准备状态。接着在幼儿探究的过程中,我指导他们通过自身的探索,对两面镜进行感知、操作、发现问题、寻求答案。其间,我尊重接纳每个幼儿的观点,积极正确评价每一个幼儿的探究行为,对认真探索、积极动脑的幼儿加以肯定和表扬;对能力差的、依赖性较强的幼儿总是给予鼓励的支持,帮助孩子树立自信心,从而进一步调动幼儿主动的积极性,使他们的探究活动真正做到自主,学习的内驱力在中得以充分发挥,目标大成度高。
