In the field of education, k 12 cc usually refers to the learning content related to natural science in the basic education stage. K 12 CC, that is, "implementing the practice outline of science and engineering among students in grade k- 12", aims to improve students' scientific literacy and innovation ability by allowing them to carry out scientific research and engineering practice, and to train students to become scientists and engineers who will contribute to society in the future.

The learning contents of k 12 cc include science, mathematics, engineering, technology and other fields, all of which are to help students master the latest scientific and technological knowledge. In the learning process under the framework of k 12 cc, students will face challenging problems, which need to be solved through independent thinking and experiments. This way of learning pays attention to students' autonomy and innovation, and encourages students to explore the same problem in various ways.

With the popularization of Internet technology, the implementation mode of k 12 cc is replacing the traditional teaching mode and becoming one of the main ways of education and teaching in the future. K 12 cc advocates students to exert more subjective initiative in the whole learning process, cultivate innovative thinking and problem-solving ability, master more diversified scientific knowledge, and cultivate more useful talents for the future science and technology industry. Therefore, k 12 cc will effectively promote the development of future education and enable more students to realize their self-worth in independent practice.
