What is Xiaosi AI?
XiaoSi AI is an AI learning product launched by Xueersi. Its official website takes "Asking better questions is better learning" as its external proposition. Based on the Jiuzhang Large Model, it provides problem-solving and Q&A support. The product concept tends to be guided explanation, that is, helping students figure out the answers on their own through follow-up questions and prompts instead of directly giving the answers. For students who hope to train their thinking process rather than just pursue results, this design has practical significance and is closer to the original purpose of teaching. For students who prefer to be guided rather than directly fed answers, this interaction method is worth long-term use, and it is also easier for them to accumulate real problem-solving experience.
Who is it for?
- Primary and middle school students: When they get stuck on problems, they need guidance on thinking rather than directly copying answers to get through homework and exercises.
- Parents: They hope to guide their children during tutoring, avoid making the child dependent by directly giving answers, and gradually let go.
- Teachers: It is used to design heuristic questions, serve as a reference for classroom interaction and example explanation, and enrich teaching methods.
- Learners who need to build a solid foundation: It helps them identify exactly where their understanding gaps lie and then make targeted improvements.
Key features
6Guided Problem-Solving
The official emphasis is on driving thinking through questions, guiding students to understand the problem-solving path through step-by-step hints rather than directly presenting the final answer.
Support from the Jiuzhang Large Model
The product is supported by the Jiuzhang Large Model developed by Xueersi. It provides analysis and explanations for subject-related questions, making it targeted for educational scenarios.
Multi-round Interactive Q&A
It is used in a conversational manner, allowing users to continue asking follow-up questions about the same problem until they fully understand the key steps and the underlying conceptual principles.
Focus on subject scenarios
The official website takes math Q&A as the entry point, suitable for explaining calculation, application and geometry problems at the primary and secondary school levels.
Learning concept communication
The official regards the ability to ask questions as one of the learning goals, which is suitable for cultivating the habits of independent thinking and active questioning.
Heuristic Guidance Design
Compared to directly providing a complete solution, the product tends to give hints first and then gradually narrow down the scope, allowing students to retain space for their own reasoning.
How to use Xiaosi AI
- When using it, first state your own train of thought.
- it will be easier for the AI to point out the specific step where you made a mistake, rather than repeating the entire process verbatim.
- If the model's explanation is inconsistent with the textbook's methods, follow the textbook and your teacher's instructions and take the initiative to verify with your teacher.
- Take the guidance process as an opportunity to practice thinking.
- It is not recommended to directly ask for the final answer and skip the derivation process, as the benefits will be limited.
- For math problems, ensure that symbols, units and conditions are complete when inputting.
- ambiguous expressions will significantly affect the accuracy and availability of the explanation.
- Be wary of the illusion of "seeming to understand" with learning tools: the step-by-step solutions provided by AI are smooth, but skipping your own derivation process won't lead to long-term memory.
- It is recommended to use it as a practice partner you can ask at any time, not as a shortcut to do your homework for you.
