HERNANDEZ-JUNCO, Luisel et al. The laboratory practice in the subject General Chemistry and its research approach. Rev Cub Quim [online]. 2018, vol.30, n.2, pp.314-327. ISSN 2224-5421.

In order to contribute to the research approach in the laboratory practice in the subject General Chemistry, didactic procedures are exposed. These procedures are based on the following elements: the methodological approach to conduct experiments in the Natural Sciences, the special didactic for teaching Chemistry regarding the teaching of the chemical experiment, its forms of organization, the experimental task, the levels of complexity, the stages to train the experimental skills and the connection between the experiment and research. Within the didactic procedures proposed, the requirements for the direction (guidance, execution and control), the organization from the interaction objective-content-experimental tasks, the development of experimental skills (stages and levels), evaluation and control are considered. The results presented constitute a flexible proposal, applicable to General Chemistry in majors related to the natural sciences, since it allows improve the scientific training based on laboratory practices.

Palavras-chave : methodological approach; experimental skills; didactic procedures; experimental tasks.
