The new curriculum of 12-year basic education officially debuted after the start of school in August 2019. Even though the literacy, indicators and learning performances have been listed, the three stages of primary school learning are not planned in the science and technology field. The scientific and technological literacy, learning content and learning performance indicators were also deleted in full, which led to teachers and students a sense of abandonment and a panic about the connection between science and technology curriculums in high school. This paper summarizes the evolution of the small science and technology field in the country, and learns and designs a brand new curriculum for the simplification of the small and medium-sized, inter-disciplinary (information, life science and technology, characteristics or school-based) courses. The new model of teaching plan is a feasible solution to solve the problem of class assignment, teaching and suffering without teaching materials. It can effectively reduce the burden of teachers and students and can effectively learn.
