Children develop narrative skills by understanding and actively building connections between elements, image text matching, and consequences. However, it is challenging for children to clearly grasp these multi level links only through explanations of text or the facilitator's speech. To address this, we developed Colin, an interactive storytelling tool that supports children's multi level narrative skills through both voice and visual modalities. In the generation stage, Colin supports the facilitator to define and review the generated text and image content freely. In the understanding stage, a question feedback model helps children understand multi level connections while co creating stories with Colin. In the building phase, Colin actively encourages children to create connections between elements through drawing and speaking. A user study with 20 participants evaluated Colin by measuring children's engagement, understanding of cause and effect relationships, and the quality of their new story creations. Our results demonstrate that Colin significantly enhances the development of children's narrative skills across multiple levels.

翻译：儿童通过理解并积极构建元素间的联系、图文匹配以及因果关系来发展叙事技能。然而，仅通过文本解释或引导者的口头讲解，儿童难以清晰掌握这些多层级关联。为此，我们开发了Colin，一种通过语音和视觉模态支持儿童多层级叙事技能的交互式故事创作工具。在生成阶段，Colin支持引导者自由定义并审阅生成的文本与图像内容。在理解阶段，问题反馈模型帮助儿童在与Colin共同创作故事时理解多层级联系。在构建阶段，Colin通过绘画与口语表达积极鼓励儿童在元素间建立关联。一项包含20名参与者的用户研究通过评估儿童的参与度、因果关系的理解程度以及新创故事的质量，对Colin进行了验证。结果表明，Colin显著促进了儿童多层级叙事技能的发展。
