This study constructs two different model structures called projective and injective model on the category of differential graded modules over a differential graded ring and also provides an explicit description of fibrant and cofibrant objects for these models. The constructions are based on the concept and properties of semi-projective and semi-injective modules and other kinds of projectivity and injectivity in the category of differential graded modules. Also an analysis of behavior of functors; restriction, extension and co-extension of scalars is given. Furthermore, some conditions under which an adjunction becomes a Quillen pair and a Quillen pair becomes a Quillen equivalence are described. Additionally, a relationship between restriction and co-extension for compact Lie groups is discovered.
