As learning moves online, the way students talk to teachers is changing. In Vietnam, during periods of remote study, many teachers noticed students sending messages as if they were texting friends. These messages often arrived late at night and used very informal language. This new digital environment requires students to learn a more professional style of communication to ensure their questions are understood and answered effectively.

To get a helpful reply, you must avoid common mistakes. Firstly, never write your entire message in capital letters, as it looks like you are shouting. Secondly, avoid using slang or text-speak like ‘u’ instead of ‘you’. This language is inappropriate for formal communication. Finally, always include a subject line. An email with no subject might be missed by your teacher or even go into the spam folder.

A good email has four key parts. It starts with a clear subject line, for example, "Question about History Homework." Then, use a polite greeting like "Dear Mr. Minh." The main body of the email should be concise and clearly state your question or problem. Don't write a long, confusing story. Lastly, end with a formal closing such as "Sincerely," or "Best regards," followed by your full name and class.

Why is this important? Writing a professional email shows respect for your teacher's time. It also makes it easier for them to give you the help you need. A clear, respectful email is more likely to receive a fast, useful response. This is especially true when you have important questions about the high school entrance exam, where a good answer is critical.
