A mediação de tecnologia sustentável no ensino e aprendizagem em ciências implementado ao cultivo hidropônico

Abstract

This work presents the use of sustainable technology, which is the concept related to the adoption of good practices in the exploitation of natural resources, involving the use of technology to promote the sustainability of the environment. This work covers a proposal of extraclass activity that allows a qualitative data collection, where the teacher can explore through the process of mediation, the participation of its students, creating subsumes in their cognitive, focusing on a non-mechanical learning of contents. The process of mediation occurs in a participatory way between the mediator (teacher) and the learner (students), stimulating a reflexive and critical thinking with a CTS vision. In this learning environment, the garden, students can interact directly with a learning tool that covers energy transformations, through the information provided by the operation of a wind generator and the installation of a photovoltaic board, comprising concepts of sustainable energy and sustainable technology , in addition to the chemical controls that occur in the hydroponic system, such as pH, concentration, inorganic nutrients function and water electrical conductivity. In this process the student will also be able to contemplate the operation of the Arduino micro controller and through the basic programming will be able to develop more complex automated projects. The importance of this project is to arouse students' interest and curiosity in the study of science involving the use of technology, which is part of their day-to-day life.
