Abstract:

Objective:
With the aim of improving the basic competences evaluated in the SABER PRO test at the National-Center-of-Hotels-Tourism-and-Food-Industries (CNHTyA), parallel tests (two types of diagnostic tests) were carried out in natural sciences that were the antecedent for the design and application of guidelines of learning, that framed the strategies used for the strengthening of basic competences in Natural Sciences from the MPFPI (Pedagogical Model of the Integral Professional Training) in the CNHTyA.

Methodology:
Between 2017-2018, it was realized a descriptive investigation of case of study with a quantitative approach where a pedagogical strategy is designed and applied to develop basic skills in Natural-Sciences. The descriptive research is carried out with a quantitative approach based on the parameters of the SENA from pedagogical engineering (SENA, 2014A); (SENA, 2014B); (SENA, 2014C) in order to strengthen basic skills in Natural Sciences in the CNHTyA, which required:
- Diagnostic instrument design.
- Application of the instrument.
- Analysis of the information.
- Determination of training needs by competences.
- Plan the training to be developed.
- Plan the learning route that will allow the installation of skills in the trainees (SENA, 2014B).

The methodology used for the diagnosis consisted of taking the information of 991 trainees distributed in 51 records of all the CNHTyA coordinations following 6 steps:
1. Identification of the required competences.
2. Definition of what, how, where and when the test was to be performed.
3. Definition of the type of instrument to be used
4. Design of the evaluation instrument.
5. Formulation of the evaluation criteria.
6. Validation of the diagnostic process. Validation of the instrument

Result:
Through The Methodology there were a numerical increase in the development of all competencies (explanation of phenomena, comprehensive use of scientific knowledge, inquiry) by 40%, which was possible through the contextualization of the application of the guide when identifying the learning styles of apprentices. For the identification of learning styles within the training environment, something that the MPFPI (Pedagogical Model of the Integral Professional Training) did not contemplate, as the starting point to structure the learning guides to the training needs, the instrument of Alonso, Gallego & Honey (1994) has been used. In this way, the strengthening of basic skills in Natural Sciences from the Pedagogical Model of Integral Vocational Training at the CNHTyA, has seen learning as a cyclical process in which the identification of learning styles promotes success in learning and the achievement of the objectives that are outlined as an instructor.
