Prepare the soil based on its physical properties with a look to the future

Abstract

Preparing the agricultural soil from the physical properties, taking into account its conservation and restoration, is one of the professional skills foreseen in the model of the professional of the Agronomy career at the University of Pinar del Río. The training and development of professional skill is a problem and is of great importance in the professional performance of
the future engineer, so their training is intensified during the teaching-learning process of Physics at the University of Pinar del Río. The article aims to show the indicators that define the training and development of professional skill and the results achieved in a group of 18 second-year students, who are subject to three controls at different times during the development of the subject of classical mechanics. To meet this goal, three controversial situations are elaborated with which the results are validated through a double classification analysis of variance (ANOVA). The results achieved show that the initial training of the skill is quite adequate because when using the sum of the squares of the deviations, 85.31 percent of the students are determined by the exercise of the indicators.
