In the digital society emerge educational approaches mediated by digital technologies that aim to respect the time, pace and form of learning of each student individually. The main ideas embedded in the logic of blended and adaptive learning - autonomy, student protagonism, customization, monitoring and continuous evaluation of learning - are not new and are also present in traditional classroom-based education. The main difference lies in the fact of recognizing in technology the potential of expanding the forms and places of learning, providing a parallel and integrative way, not substitutive and not simply complementary to face-to-face teaching, in order to achieve learning objectives. The general objective of this research is to present the conception, operationalization and implications of two educational approaches mediated by digital technologies, blended learning and adaptive learning. The thesis was structured in the multipaper format containing three independent studies that safeguard thematic unit and theoretical alignment, thus maintaining an interrelation. The adoption of an alternative model for writing the thesis responds to the demand for the research object, which is plural, diffuse and multifaceted. The first study, a systematic survey of the literature from the academic production in the area of Informatics in Education, sought to identify the conceptions and characteristics of hybrid and adaptive models that aim at personalization of learning. The second study is the report of an online training experience for teachers that sought to explore the concepts of blended and adaptive learning, as well as to mobilize mechanisms for its operationalization. The third study aimed to verify, from the teachers perception of the degree programs and the curriculum analysis of their courses, if the initial teacher training is in line with the emerging educational approaches mentioned above, as well as their intertwining with specific and complementary public educational policies, which aim to promote the incorporation of digital technologies into education. This work has also an introduction, where the theoretical and conceptual framework of the three studies is presented, as well as a conclusive synthesis, presenting an integrated discussion of the results. The research results show the need for greater interaction between professionals in the areas of Informatics and Education in the development of environments and systems that support personalized learning, which implies in the accomplishment of more experimental research and, mainly, in the reconfiguration of the teacher training in order to effectively prepare teachers to play their role, which is no longer a transmitter of knowledge but a mediator in the learning process, re-signifying its modus operandi based on the principles of curatorship, design and orientation.
