nook and cranny cleaning tools

The following is a reflection on the cleaning tools teaching activities: ** 1. Setting goals ** 1. ** The target should be focused on the core content ** - In teaching activities related to cleaning tools, the goal should not be too scattered. For example, the activity goals included things like " learn to control your emotions and not cry when you're sad or in pain " and " understand the main symptoms, and understand the self-protection awareness of prevention and treatment ", which were not strongly related to cleaning tools. This would cause the focus of the activities to be not prominent, and it would be difficult for teachers to design and guide effective teaching activities around a core during the teaching process. 2. ** Increase the difficulty of the target ** - The difficulty of setting the target had to be increased. If the goal of the whole activity is not challenging, the child's ability development in the activity may be limited. For example, it only stopped at the basic level of understanding the names and uses of cleaning tools. It did not further guide children to explore the working principle of cleaning tools or the optimal selection of different cleaning tools in different scenarios. ** 2. Teaching process ** 1. ** The purpose of a toddler's operation ** - In the process of children operating cleaning tools, it was necessary to strengthen the purpose of the operation. If the child was only playing with the tools and lacked a clear operation task, such as just feeling the tools without a clear cleaning task, the educational value of the operation process would be greatly reduced. Teachers should design operation tasks with clear purposes in advance. For example, by setting up different cleaning scenes, children should choose the appropriate cleaning tools according to the needs of the scene and complete the cleaning work. 2. ** The continuity between links ** - There needed to be a clear link between the teaching segments. For example, from understanding cleaning tools to class labor day activities, to sharing the results of labor, the transition between each link should be natural and smooth. If there was a lack of connection between the links, the entire teaching activity would seem stiff and fragmented. It would be difficult for children to establish a complete knowledge system and operational experience system in the activity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
