Networked learning is part of an emergent networked society. As such networked learning forms part of a wider debate concerning the nature of social processes, power and culture and their relationships with technology.

The context of higher education has been changing alongside the introduction of new technol
Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will
Interpreting Electrospray Mass Spectra
This site is a tutorial on interpretation of electrospray mass spectra of multiply charged molecules. It provides a simple explanation of the electrospray process and the potential for the creation of multiply charged species, especially when working with peptides. The mathematics of determining the charge state and molecular weight of the peptide is also explained. Although this site provides a good foundation on electrospray MS of peptides, students requiring an advanced understanding of MS
