Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
The contents are initially developed in a theoretical and practical way through lectures, open to questions and discussion. These will allow the basic framework necessary for the understanding of physics in everyday experiences. These classes will be complemented by more practical classroom and field activities, followed by presentation and discussion of experimental activities. Through the development of a group investigation, students define a research theme, making observations, recording and analyzing the results to draw a conclusion. This work will enable them to develop core competencies for understanding experimental science teaching. The evaluation will consist of two individual written tests related to the theoretical component (50%), the delivery of a laboratory notebook with the activities performed (25%) and the oral presentation and presentation of group research work (25%).
