摘要：

技术的进步提高了教学代理的语言能力，也使创建AI生成教学代理成为可能。但不同认知风格学生适合何种语言风格教学代理尚不清晰，其AI生成教学代理是否有效也有待探究。为此，实验1考察了会话和正式风格教学代理对不同认知风格小学生视频学习的影响。结果发现，场独立学生在两种条件下的社会临场感、认知负荷和测验成绩均无显著差异；场依存学生在会话风格条件下的社会临场感和测验成绩更高，且场依存学生的社会临场感在教学代理语言风格和测验成绩间起完全中介作用。实验2进一步探究了相较于真人会话风格教学代理，采用AI生成语音、AI生成语音及仿真形象和AI生成语音及卡通形象方式创建的会话风格教学代理对场依存学生是否同样有效。结果发现，AI生成语音及卡通形象的会话风格教学代理进一步提高了场依存学生的测验成绩。上述结果表明，会话风格教学代理对场依存学生更有效，AI生成语音及卡通形象的会话风格教学代理能进一步提高其学习效果。

Abstract:

Technological advances have improved the language capabilities of pedagogical agents, enabling the creation of AI-generated pedagogical agents. However, it is unclear which language style of pedagogical agent is appropriate for students with different cognitive styles, and further exploration is needed into the effectiveness of their AI-generated pedagogical agents. Therefore, Experiment 1 examined the effects of conversational and formal style pedagogical agents on video learning among pupils with different cognitive styles. The results indicated no significant differences in social presence, cognitive load, or test scores between the two conditions for field-independent students. However, field-dependent students exhibited higher social presence and test scores in the conversational style condition than in the formal style condition; the social presence in field-dependent students fully mediated the relationship between language style and test scores. Experiment 2 further examined whether the conversational style pedagogical agents created using AI-generated voice, AI-generated voice and human-like appearance, or AI-generated voice and cartoon appearance were equally effective for field-dependent students, compared to real-human conversational style pedagogical agents. The results indicated that only the conversational style pedagogical agents created using AI-generated voice and cartoon appearance further improved the test scores of field-dependent students. These findings suggest that conversational style pedagogical agents are more effective for field-dependent students, and their effectiveness can be further enhanced when they are created using AI-generated voice and cartoon appearance.

Key words: pedagogical agent, language style, cognitive styles, AI-generated pedagogical agents, pupils
