Writing in complete and grammatical sentences is absolutely necessary in academic writing. If you must make a point in an essay or a writing assignment, then write strong sentences that may prevent your argument from being dismissed offhand by someone who sees grammar errors that may reflect poorly on your ideas or thoughts. In order to avoid making such mistakes, consider purchasing a Modern Language Association (MLA) handbook/style guide. The MLA is an organization of teachers and professors that determine what makes up correct writing practices.
Periods, commas, semicolons and the other punctuation marks all have specific uses and meanings. Your writing should reflect an understanding of the differences. An MLA handbook can assist you in learning the appropriate use of punctuation marks in formal writing.
It is of the utmost importance that your thoughts be understood by whoever evaluates your writing; moreover, your writing needs to make sense to your reader or readers. The student in an English class does well to remember that his thought process is unique and readers will not necessarily understand the connections between ideas and sentences in his writing unless he makes those connections clear. In many cases, his writing will need a main point or controlling idea. This main idea will be supported by all of his other sentences. The reader will need to understand the connections between the supporting information and the main idea.
In many cases, an English class will require research. Research develops your argument by supporting it with credible facts and information. Ideally, a student will find new and interesting sources of valid information rather than consult sources too often used by other students. If you can find new information and perspectives, then your writing will be full of new ideas and insights. Teachers appreciate solid writing with new approaches.
Many instructors expect you to participate during class sessions. This may involve answering questions presented in class, providing insightful comments, or giving feedback to the ideas of other students. Keeping up with your reading and spending a reasonable amount of time thinking about what you learn will enable you to participate in a meaningful way.
