Abstract :Individuals are expected to have multiple skills in order to be successful participants in the society of the future. This expectation has also changed the understanding in the education-teaching process. Considering the changing needs in the changing world, it can be said that innovative practices should be developed in the learning-teaching processes in order to raise individuals equipped with the basic skills required in the 21st century. For this reason, it is very important to re-code learning processes through these changes. With the rapid development of technology in the globalizing world, competence in communication and language skills forms the basis of success not only in academic but also in daily life. Therefore, the increasing demand for the development of these skills has created a new literature on the skills of this century. 4C skills have been added to this literature in recent studies. This concept, abbreviated as 4C skills, is actually a combination of communication, collaboration, critical thinking and creativity. These skills are considered key skills for 21st century students. From this point of view, in this study, within the framework of the future of language lessons, what the 4C skills are and how these skills can be applied in the field of language teaching by integrating them with 4 basic language skills (reading, writing, listening, speaking).The connections of 4C skills with language teaching and their contribution to the development of 4 basic language skills have been tried to be explained. By examining the 4C skills, it is discussed what is happening in the 21st century understanding of education and what may happen in the future, and how these changes can affect language teaching. As it is known, interactive technological tools and innovative applications developed in the education process offer new methodological approaches to teachers. In order for these new methodological approaches to be learned and applied in the classroom, the curricula must be updated and the skills combined with these new methodological approaches must be included in these programs. In addition, teachers should support their students to acquire these skills. At the end of the study, primarily suggestions for the language learning-teaching process were presented to the program makers and teachers. At the end of the study, it has been suggested what can be done in the language teaching-learning process for these skills. Keywords : 21st century, language skills, 4C skills, education, training
