1 Introduction

The proliferation and intelligence of mobile terminal devices are introduced, along with the advantages of mobile learning such as convenience and personalization. It is also noted that mobile learning is primarily realized through apps. Using HelloChinese as an example, its influence as a Chinese teaching app and user evaluations are discussed. The research focus is on analyzing the app's course design, including content, concepts, and methods, aiming to explore its success factors to guide the development of Chinese learning apps and support the international dissemination of Chinese.

2 Mobile Micro-Learning Theory

Introduces the theory of mobile micro-learning, including its fundamental characteristics such as mobility, micro-nature, ubiquity, interactivity, personalization, and sociality, as well as the composition of mobile micro-learning systems. Key emphasis is placed on analyzing the characteristics and design points of learning content.

3 Analysis of HelloChinese's Course Content, Teaching Philosophy, and Teaching Methods

This section provides an in-depth analysis of the course content, teaching philosophy, and teaching methods of the HelloChinese app. First, through comparison with the "International Chinese Language Education Chinese Proficiency Grading Standards," it is found that HelloChinese's teaching content is comprehensive at the elementary Chinese level, covering pinyin, Chinese characters, vocabulary, grammar, and more. It is aligned with HSK levels and suitable for beginners. The course is divided into four modules: "Learn," "Practice," "Stories," and "Immerse," featuring diverse topics and presenting texts in story form, emphasizing pragmatic communication skills and cultural experiences.

In terms of teaching philosophy, HelloChinese emphasizes gamification, immersion, micro-learning, and personalization. Gamification motivates learners through learning goals, progress feedback, and achievement displays, though it lacks sufficient progression levels. Immersive teaching enhances the learning experience by simulating teaching scenarios and interactions, but the level of interactivity needs improvement. The micro-learning course design aligns with the characteristics of mobile micro-learning, with small topic granularity, making it convenient for learners to utilize fragmented time. Personalization is reflected in the adaptive learning system and adjustable learning settings, catering to the needs of different learners.

In teaching methods, HelloChinese primarily employs quiz-based teaching, podcast teaching, and story-based teaching. Quiz-based teaching reinforces learning through tests, though there are accuracy issues with the answers. Podcast teaching uses audio materials to simulate real dialogue scenarios, enhancing the fun and practicality of learning. Story-based teaching presents texts in story form, increasing learners' engagement and interest. These teaching methods are grounded in behaviorist learning theory, emphasizing the connection between stimulus and response, as well as the role of reinforcement, to improve learning outcomes and motivation.

4 Suggestions for Improving HelloChinese's Instructional Design

Suggestions for improving HelloChinese's instructional design are proposed. First, it is noted that there is room for improvement in interactivity and social learning. The development of built-in social platforms and notification systems is recommended to promote learner interaction and community building. Second, regarding the quality of quiz exercises, optimizing the speech recognition system, establishing a professional content review team, and incorporating large language model technology to enhance translation exercises are suggested. Finally, for game design, introducing competitive game mechanisms and designing hierarchical game levels are recommended to increase the fun and challenge of learning.

5 Conclusion

Summarizes HelloChinese's teaching content, philosophy, and methods, noting its suitability for beginners. However, it also points out shortcomings in interactivity, sociality, quiz quality monitoring, and gamification challenges, while looking ahead to future directions for Chinese learning app development.
