1. Personalized teaching: Artificial intelligence technology can provide personalized teaching programs according to students' learning data and characteristics to help students learn and master knowledge better.

2. Intelligent CAI: Artificial intelligence technology can provide intelligent CAI tools, such as speech recognition and intelligent translation, to help students better understand and master knowledge.

3. Teaching quality evaluation: Artificial intelligence technology can help teachers evaluate teaching quality, find problems and deficiencies in teaching in time, and thus improve teaching quality.

However, artificial intelligence has also brought the following negative effects to the development of modern education:

1. Artificial intelligence replaces teachers: Some people worry that the development of artificial intelligence technology may replace the role of teachers, resulting in the loss of humanization in the teaching process.

2. Privacy issues: Artificial intelligence technology needs a lot of student data, which may lead to privacy issues, such as the disclosure of students' personal information.

3. Technical dependence: Excessive dependence on artificial intelligence technology in education may lead students to lose interest and ability in traditional learning methods and knowledge acquisition methods.
