ANALYSIS OF PRACTICAL LABORATORY WORKS PREPARED BY FUTURE TEACHERS OF NATURAL SCIENCES

This work aims to study on practical laboratory works elaborated by a group of future teachers in physics and chemistry, at the province of San Juan in the Argentine. The objective was to analyze the proposals presented by students in the framework of an extracurricular workshop. We identify strengths and weaknesses, in order to propose actions for the improvement of future teaching performance. We analyze protocols based on previously established categories. Results show different elements that could be facilitators or impediments to the successful performance in the future teaching practice on Natural Sciences. Among facilitator elements, we found the presence of contextualized situations, and the adaptation to the school level of the students. Meanwhile, among the obstacles, can be mentioned the absence of activities that promote progress from observations to interpretations. For all of this, it would be advisable to train future teachers in the revision of their experimental designs, looking to consider observations, incorporate analyzes that lead to interpretations, and finally, propose activities to mobilize these new learnings to apply in the analysis and resolution of everyday situations.
