Therefore, when carrying out scientific education activities, young teachers should make reasonable use of the surrounding environment and educational resources, and create a scientific teaching environment that meets the psychological characteristics and thinking needs of young children according to their physical and mental development laws. Teachers should also play their own guiding role to lead children into scientific exploration, so as to enable children to construct scientific concepts, enhance scientific experience and develop scientific attitudes in scientific exploration, thus effectively cultivating children's scientific literacy. Based on this, this article will think about the significance and current situation of science education activities in kindergartens.展开更多

Innovative career calls for innovative talents. To lead the world in scientific and technological innovation, China must discover talents in innovation practices, cultivate talents in innovation activities and pool talents in innovation undertakings." The grand blueprint of "accelerating the building of an innovative country" described in the report of the 19th CPC National Congress is desirable. Chongqing youth science and technology model competition is a traditional competition project which is jointly sponsored by Chongqing science and technology association and Chongqing education commission. The event has been held every year since 1990 and has been held for 24 consecutive years. This paper summarizes the development situation of the 24th Chongqing youth science and technology model competition "Electronic Baipin", analyzes the data of the competition, summarizes the experience of the competition, in order to provide reference for the future holding of related competitions.展开更多

This serves as a unique and valuable means of the public communication of science and technology and informal science education activities, with the public at the centre of the process. To achieve this, SRWs integrate action and reflection not as a dichotomy, but as a complementary relation in which sensorial interaction is not a thoughtless process and mental activity is not disembodied. In this way, SRWs create virtuous cycles of meaningful learning.However, SRW practitioners thus far have not paid enough attention to the development of a theoretical foundation to support their strategies;they remain highly dependent on empirical experience and tacit knowledge. The little attention paid to the creation of a conceptual framework represents a critical barrier for reflection, discussion and, with them, the maturation of the SRW community.This work links a characterization of the SRW, built upon empirical experiences, to a variety of learning theories to identify an essential basis for discussion on the subject. Our objective is to complement the rich empirical tradition of the SRW with analytic elements intended to encourage discussion and promote—as tends to happen in activities with the public—virtuous cycles of theory and practice.展开更多
