Augmented reality is a technology that allows combining realworld life with digital information, through other technologies such as computers, tablets or smartphones. Currently, it is used in diverse areas such as advertising, medicine, arts and education, among others. This research was carried out in the city of Ocosingo, Chiapas, Mexico, in a context where it is difficult to access technology and, above all, connectivity. It focused on using augmented reality in a didactic sequence for the teaching and learning process of the circulatory, respiratory and digestive systems in the Natural Sciences subject, in order to demonstrate whether the use of this technology as a didactic tool allows 4th grade students to improve their academic performance. The study was carried out under a quantitative, quasi-experimental and descriptive approach, using data collection tools such as tests designed with dichotomous responses (pre-test and post-test) and surveys with closed-ended questions under the Likert scale. The results show that using augmented reality in the teaching and learning process, within the classroom, significantly increases the academic performance of students compared to the traditional way of teaching these topics in the aforementioned subject.

The mixed methodology (Blended Learning) seeks to implement the use of Information and Communication Technologies (ICT) to provide studies of Technological Higher Education to people who are immersed in the labor market. This modality was implemented for the first time at the Universidad Tecnologica La Selva, located in the city of Ocosingo, Chiapas, for the educational program of Information Technology Engineering. This research focused on knowing the perception of the students who pursued their professional career under this modality and who are currently employed, the study was carried out under a non-experimental quantitative approach with descriptive transactional design, which evaluated the educational platform used, the teachers and the study modality. A survey with closed questions under the Likert scale and an open question for suggestions that allowed improving this modality were used as an information collection tool. The results show that for students who are immersed in the labor field, blended learning is excellent to continue with their professional studies since they can manage their time, moreover, they hope to improve their professional performance as well as their economic conditions when getting a professional engineering degree.
