The construction of a scientific educational material platform based on the digital interactive service model mainly solves two problems in science education: one is to solve the problem of quantity and quality of teaching materials; the other is to construct the cognitive-involvement-inquiry learning process of scientific knowledge and help learners gain “meta-cognitive abilities” for the ontology of science education. The design of this platform adopts the form of new media, based on internet thinking, cloud storage, big data technology, and integrated terminal equipment applications, with a view to establishing a nationwide non-differentiated teaching material platform. The science education teaching material is essentially digitally oriented. Therefore, this paper designs the function and application model of the platform based on the digital interactive service model and constructivism learning theory. The platform design includes two paths and six modules. The two paths are “content chain” and “information transmission chain”; the six modules are: collection of teaching materials, content planning of teaching materials, brand packaging of teaching materials, platform software development, cloud storage services, and terminal equipment integration. The application of the platform, the use of digital technology, co-construction and sharing of ideas, across the time and space constraints, scientific education for science education, art, visualization of digital teaching materials, stimulate students' thirst for knowledge, enhance the expressiveness of knowledge, and improve the overall effect of science education.
