Contractions, in which two words are shortened and combined into one word (e.g., "I'm" and "isn't"), are usually reserved for informal communication. Since academic writing typically has a formal style, contractions should generally be avoided. Instead, spell out the words in full: "I am" and "is not". If you are writing a document that requires an informal style, you could check with your instructor as to whether contractions are acceptable.
