7 communication mistakes students don’t realise they are making

Effective communication is a superpower in academics and beyond. Whether you’re giving a class presentation, emailing a professor, or collaborating on a group project, how you communicate shapes your success. However, many students unknowingly fall into common traps that dilute their message or create misunderstandings.Here are 7 communication mistakes students often make without realising — and how to fix them to boost your confidence and clarity.

Speaking without considering your audience

One of the biggest mistakes students make is using the same style of communication regardless of who they’re talking to. The way you chat with friends is different from how you should interact with professors, mentors, or potential employers. Using slang or overly casual language in formal situations can appear disrespectful or unprofessional, while sounding too stiff in casual settings can create distance.How to fix it:Before speaking or writing, ask yourself: Who am I addressing? What tone is appropriate? Match your language, formality, and body language to your audience. For example, emails to professors should be polite and clear, while group chats with classmates can be relaxed.

Overusing filler words

Fillers are small words or sounds that fill pauses when we’re thinking. While natural in conversation, overusing fillers in presentations, interviews, or formal discussions can distract listeners and reduce your credibility. They often indicate nervousness or a lack of preparation.How to fix it:Practice your speaking skills by recording yourself or rehearsing in front of friends. Become aware of your filler habits and pause silently instead of filling gaps with “um” or “like.” This creates a more confident and polished impression.

Being too passive or too aggressive in group settings

In group projects or discussions, communication balance is key. Some students shy away from contributing, fearing judgment or conflict. Others dominate conversations, unintentionally shutting others out. Both extremes can damage collaboration and learning.How to fix it:Aim for assertive communication—express your ideas clearly and confidently without overpowering others. Listen actively and encourage quieter members to share their thoughts. Practicing empathy helps build a respectful environment where all voices are heard.

Writing emails like text messages

Emails remain a primary way students connect with professors, admissions officers, or potential employers. Yet many write emails as if texting friends—informal greetings, slang, missing punctuation, or vague requests. This casual approach can hurt your image and delay responses.How to fix it:Treat emails as professional communication. Use a clear subject line, proper greetings (e.g., “Dear Professor Singh”), and polite language. Be concise but specific about your purpose. End with a courteous closing like “Thank you” or “Best regards.” Always proofread before sending.

Avoiding eye contact and poor body language

Nonverbal cues like eye contact, facial expressions, and posture play a massive role in communication. Students often underestimate their power. Avoiding eye contact can make you seem disinterested or untrustworthy, while slouching or fidgeting can signal nervousness or lack of confidence.How to fix it:Maintain comfortable eye contact to show engagement and confidence. Sit or stand upright to project energy and openness. Practice in front of a mirror or record yourself to become aware of distracting habits. Remember, your body speaks as loudly as your words.

Not actively listening

Communication is a two-way street. Many students listen with the intent to reply, rather than to understand. This leads to missed information, misunderstandings, and weaker responses—especially during lectures, group discussions, or interviews.How to fix it:Focus fully on the speaker without interrupting. Use verbal and nonverbal cues like nodding, paraphrasing what you heard, or asking clarifying questions. This shows respect and helps you absorb information better, making your responses more relevant and thoughtful.

Assuming everyone understands what you mean

It’s easy to forget that your background, experiences, and knowledge shape how you communicate. Using jargon, abbreviations, or vague phrases without explanation can confuse classmates or instructors unfamiliar with your context. This often happens during presentations or collaborative work.How to fix it:Aim for clarity by explaining unfamiliar terms or ideas. Check for understanding by inviting questions or feedback. When writing, keep sentences simple and organised. If presenting, use examples and visuals to make concepts easier to grasp.Strong communication skills don’t come automatically—they grow through awareness and practice. By avoiding these common mistakes, you’ll not only improve how you express ideas but also how you connect with others. This sets a solid foundation for academic success, career opportunities, and lifelong relationships.
