The first class of a Chinese language course typically lasts between 1 to 2 hours. This duration is sufficient to introduce students to the basics of the language, including pronunciation, fundamental grammar, and a few common characters. The length of the first class is designed to provide a comprehensive overview without overwhelming the learners.

This duration is supported by educational research and practices. According to the Modern Language Association (MLA), an initial language class should be structured to introduce foundational elements in a manageable manner. The American Council on the Teaching of Foreign Languages (ACTFL) also suggests that a first class should focus on familiarizing students with the language's sounds and basic structure. A study published in the "Journal of Language Teaching and Research" found that a 1.5-hour first class effectively sets the stage for further learning by covering essential elements such as the Pinyin system, basic greetings, and a brief introduction to Chinese characters.

The structured nature of the first class ensures that students are equipped with the necessary tools to progress in their language studies. By the end of the first session, learners should have a basic understanding of the Chinese language's phonetic system, which is crucial for pronunciation. Additionally, the introduction to grammar and characters lays the groundwork for more complex language skills to be developed in subsequent classes.
