Abstract: Under the background of educational informatization， the construction of digitalteaching materials has entered the stage of comprehensive exploration. The construction of“scale + characteristics”of digital teaching materials empowered by information technology willevolve from integrated application to innovative development. The large-scale and characteristicconstruction of digital teaching materials have similarities in value and differences in practice. Theyare opposite to each other and complement each other， showing the contradiction of “separation”and “combination”. Starting from technology empowerment， this paper constructs the operationlogic of the construction of “scale + characteristics” of technology empowerment digital teachingmaterials from three core dimensions： probing realistic challenges， the mechanism of technologyempowerment， and the possible ideal results. At present， the development of new era mustbe active docking requirements， from the perspective of theory and the future development ofthe global， broken state simultaneously， broaden the thinking， more support， more measuressimultaneously， through technology can assign digital textbooks strategic transformation of theconstruction of the “scale + characteristics”， go with characteristic scale， quality and quantity ofdigitalization construction of teaching material.
