taken the exam of Environmental Technical Physic

Development of the course

The course is developed through series of lectures, divided into blocks on specific topics and at the end of each phase of exercises designed to introduce students to the written test exam. As part of the course students can access the course materials in electronic form on the university website consists of: as pdf files on the slides shown during the lectures, the file in pdf related to numerical exercises carried out in previous academic years and the current one, the pdf's related to the tests of previous years and the work already undertaken in the current academic session, the results of the examinations.

Learning outcomes

Knowledge
Renewable energy is becoming one of the fastest growing industries in the face of the current environmental crisis, resulting from dependence on fossil fuels and unprecedented global rate of development. To the end of the instruction the student will have to know the functioning of all types of renewable energies technologies. The Renewable Energy Program gives the student a solid foundation in the fundamental design, installation techniques required to work with renewable technologies.

Ability to apply the knowledge
The student will also acquire the following professional skills: ability to make simple energy analysis, for example, the fuel used to cool the buildings on the territory in order to make strategies for the reduction of energy consumption and sending in the gas atmosphere greenhouse. Do anyway energy issue advice to the decision-maker with the aim of producing strategies to pursue environmental sustainability, reduce the consumption of fossil fuels and reduce the phenomenon of climate change.

Soft skills
The exercises, performed by students in a collaborative way, but also independently, allow to learn, as well as the examination procedures also wrote the cooperation mechanisms in the development of energy strategies for environmental sustainability. These practices allow to acquire independent judgment, ability to learn and draw conclusions independently, but also to develop communication skills, enhanced by teamwork.

Development of the examination

Methods for assessing learning outcomes:
Oral examination

Criteria for assessing learning outcomes: 
In the oral examination, students must demonstrate that they have acquired knowledge of national and international energy scenarios, regulations and strategies to reduce the consumption of fossil fuels and reduce the resulting environmental impact. The student will learn about alternative sources of energy and technologies intended for their exploitation

Criteria for measuring learning outcomes:
Oral exam will be given at the end of course at scheduled time. At the end of the oral test is given the vote of thirty. It confirms the exam when the vote is greater than or equal to 18. It is expected to be awarded the highest marks (30 cum laude).
 
Criteria for conferring final mark:Being an integrated course the final vote is attributed jointly following the oral exam of the Environmental Sustainability module and the Energetic Resources and Alternative Energies module. Praise is given if the student demonstrates full mastery of the subject.
