Learning outcomes

The intended subject specific learning outcomes. On successfully completing the module students will be able to:
Demonstrate knowledge and understanding of physical laws and principles of astrophysics, and their application to diverse areas of physics.
Identify relevant principles and laws when dealing with problems, and to make approximations necessary to obtain solutions.
Solve problems in physics involving stars and galaxies using appropriate mathematical tools.
Use mathematical techniques and analysis to model physical behaviour of stars and galaxies and the universe.
Present and interpret information about stars and galaxies graphically.
Make use of appropriate texts, research-based materials or other learning resources about astrophysics as part of managing their own learning.

The intended generic learning outcomes. On successfully completing the module students will be able to:
Solve problems, in the context of both problems with well-defined solutions and open-ended problems. Numeracy is subsumed within this area.
Use analytical skills – associated with the need to pay attention to detail and to develop an ability to manipulate precise and intricate ideas, to construct logical arguments and to use technical language correctly.

Notes
