Several mathematical concepts have application in physics; this paper reports the results of a pedagogical investigation based on the methodology known as didactic engineering, which has been proposed with the aim of improving the skills exhibited by a group of eleventh grade students from a private institution in the interpretation of kinematic graphs. The concept of the slope of the straight line and how this mathematical concept can represent velocity or acceleration according to the variables considered in the kinematics graph provided was enhanced in the pedagogical intervention. This methodology offers a process of internal validation, after comparing the results obtained in a knowledge test at two different points in time (pre-test and post-test). The results allowed us to identify improvements in all students in terms of basic kinematics graph interpretation skills, and a group of students stood out by advancing in more complex reasoning and interpretation processes. These results contribute to the improvement of the pedagogical practices of Physics teachers at secondary and middle school levels, making them more competent when they enter higher education.

Gatekeepers Training (GKT) is one of the most widely used and disseminated programs worldwide to train personnel in suicide prevention. The purpose of the program is to acquire the necessary skills and competencies to detect psychoemotional and mental health problems that could lead to self-destructive behaviors. In this research work, the level of risk related to suicide was evaluated by means of the ISO-30 psychometric test in high school students, then the effectiveness of a gatekeeper training program applied in the Tepatitlan Regional Preparatory School (TRPS) andsome of its modules was evaluated. The results of the ISO-30 psychometry showed that 64.5% of the students evaluated have a high-riskfactor for suicide related to the inability to cope with emotions. In addition to the above, a statistically significant difference was found (Mann-Whitney U Statistics = 4322.000; p0.001) in the level of competence of the participants in relation to a pre-training evaluation.It is important to note that the effect of the difference found is strong (Rosenthal’sr=0.67) so it is concluded that the GKT drastically improved the skills and competencies of the participants.

The perception that four teachers and one hundred students have of their teaching practices with theoretical support was explored, which served as a basis for discussion, of the incidence of teacher training on the educational task, from a qualitative research, inductive method, descriptive-interpretative approach. To address subjective aspects about before, during and afterthe practice, a non-participant observation guide and a student questionnaire were used as instruments. The results allowed recovering the contributions in two constructs: the theoretical meaning and the formative meaning. Here we present the analysis of the formative meaning that contemplates the subcategories of New Forms of Pedagogical Relationship (NFRP) articulated to critical dialogicity and Collaborative Work (CT) and derived from it, the importance of enhancing the formative nature of research.

This research reports the effects derived from the application of mathematical modelling in classroom work within the development of mathematics classes, which allowed the resignification of the concept of linear function, making use of various semiotic registers of representation applied to a wide range of everyday situations. The fieldwork was based on the application of a didactic sequence to two groups of ninth grade students from a public educational institution located in the capital city of northeastern Colombia. The students were expected to build a mathematical model that would fit the data provided framed in the situations in context in order to contribute to the re-signification of mathematical knowledge. The results show that the practice of modelling favours the motivation of students in relation to mathematical knowledge, giving it meaning and significance when confronted with real situations.
