<![CDATA[Learning in the perspective of formal education is interpreted as a process that occurs in everyone during his life and runs in a complex manner. Where, in every learning activity, there will be activities that are carried out intentionally with the intention of transforming knowledge, socio-cultural values as well as norms from generation to generation in order to remain preserved. The learning process occurs because of the interaction between a person and his environment. Therefore, learning can happen anytime and anywhere. This can be proven by changes in a person's behavior that can occur at the level of knowledge, skills, or attitudes. Cultural values can be effectively implemented if students have the ability to understand and explain. These two abilities are the basic abilities to seek the development of knowledge and the preservation of an educational culture that seems to be missing in this decade. Therefore, the application of contextual learning methods, which in this study is the Practice-Theory learning method, becomes important. Action research was carried out in four learning cycles by applying the Practice-Theory learning method and the ability to understand and explain students' explanatory texts as research objects. Based on the results of the research and discussion, it can be concluded that the application of the Practice-Theory learning method can improve the ability to understand and explain and improve student achievement in grade 6 SD Negeri Ngagelrejo V/400 Surabaya.
