The 13th Five-year Plan for Education Informatization in China clearly points out that new educational models such as STEM education and maker education should be explored. STEM, as an organizational course to cultivate students' innovation ability and computational thinking in the 21st century, is in a stage of vigorous development in China. The uneven development of primary and secondary education in China is caused by the differences in economic level, geographical location and population distribution in different regions. From the perspective of STEM education, this paper analyzes the difficulties faced by Primary and Secondary Education Reform in underdeveloped areas in China and it proposes strategies of promoting intelligence in Primary and Secondary Schools based on STEM education model -- Science and Technology Games in Primary and Secondary Schools, whose content, goals, teaching process and competition rules are carefully planned and designed. The first Junior Science and Technology Games was successfully held in Quannan County, Jiangxi Province. The empirical studies show that holding Science and Technology Games for Primary and Secondary Schools in underdeveloped areas is a new attempt to explore the strategy of promoting intelligence in Primary and Secondary Schools, which provides a strong practical basis for the development of primary and secondary education in underdeveloped areas and plays a very positive role in vigorously promoting the development of primary and secondary education in underdeveloped areas, stimulating and improving the innovation and creation ability of primary and secondary students, and cultivating their computational thinking.
