“熊大熊二逛森林”是以学习序数为载体,发展幼儿观察、思维、表达等多种能力的一个中班数学综合活动。为更好地提炼幼儿的核心经验,我们通过一课二研的教学形式,围绕“连环式跟进”的教育策略设计,展开了研究。本节活动的“连环式跟进”从教学设计方面来说,是指教学环节的层层递进,以及提问设置的连环式跟进 “Bear Bear 2 visits the forest ” is based on learning ordinals as a carrier, the development of children observation, thinking, expression and other abilities of a middle school math comprehensive activities. In order to better refine the core experience of young children, we conducted a study through the teaching of one lesson and two studies, and the design of education strategies of “chain follow-up”. The “chain follow-up” in this section of activities is, in terms of instructional design, referring to the progressive progression of teaching and the continuous follow-up of question setting
