Communication barriers between students and lecturers can negatively impact students' education. Some potential barriers include speech or language differences that make it difficult for students to understand lessons or communicate due to fear or embarrassment. Boring classroom lessons can also reduce effective communication if students are not engaged. Personality differences between students and lecturers may lead to frustration if they do not connect on a personal level. Peer pressure can influence student communication as early as first grade by encouraging them to act funny or disengaged in class. A negative attitude toward a subject from students can limit good communication, so lecturers should strive to change negative attitudes.
