As a teacher I could clearly understand, through my experience, the necessity of a Science teaching involving the real context of the learner. The reflections on my teaching practice motivated me to a teaching challenge that made a relation between the student conceptual domain and the real situations in his community . Thus, the purpose of this research is to investigate evidences of a critical attidude from the CTS teaching conception through problems presented related to electrical energy consumption. I tried to answer the researching question about how to enable critical analysis from students regarding to their own use of residential electricity. This research was conducted through a qualitative approach, the action research type. A workshop was developed using conceptual energy content, in order to integrate the topics of the teaching unit. As an analysis strategy of the collected data, I developed an interpretative analysis, the intention was to give meaning to the situations raised by the students during the classes. The information was obtained through questionnaires and records in field notes. The results presented that CTS teaching approach enabled students the critical thinking mainly about values and ethical issues, relating their social reality to the habit of excessive electrical energy consumption,considering that for some students the illegal connection is a justification for wasting energy. The research has shown the dialogic and changing potential of this educational approach as the record of some students changing attitudes in that situation. I believe that, in this sense, this project demonstrated that CTS approach in schools is possible and that citizenship needs to be developed, being the technological scientific literacy of their rights and duties important for the students good achievement in society.
