Science produces new knowledge or new perceptions of existing knowledge. For example, it can provide descriptions of new or hitherto unexplored phenomena, clarify current understandings, or criticise, even refute previously established knowledge.
To create knowledge that can be approved by other scientists requires working academically and scientifically. This is how you validate new knowledge.
Working academically and scientifically
A big part of being a student is learning how to work scientifically and academically within your subject. You will need to learn about scientific methodology, academic norms and the academic genre.
Therefore, you must demonstrate that you understand the academic framework of the type of assignment you’re writing. You do this by being familiar with academic language and the academic genre, and by arguing academically.
