For students with poor academic performance, teachers' educational methods should be more encouragement than criticism. Too much criticism may make students lose confidence and motivation, which will lead to poor academic performance. Encouragement can enhance students' self-confidence and learning motivation, and promote students' enthusiasm and academic performance.

When encouraging students, teachers can adopt the following methods:

Affirm students' efforts and progress, not just pay attention to students' achievements.

Encourage students to try new learning methods and strategies to help them explore their own advantages and potentials.

Provide positive feedback and give students correct guidance and suggestions.

Stimulate students' interest and make them feel happy and satisfied with their studies.

In a word, teachers should strike a balance between encouragement and criticism, and adopt different educational methods according to students' actual situation and needs to help them realize their potential and goals.
