Practice mode · self-paced练习模式 · 自主进度

Train your thinking — one quick round at a time.训练你的思维——每次一小轮。

Skill units技能单元

Pick a unit.选择一个单元。

Each unit drills one thinking skill from the course. All 12 Track A units are ready; Track B practice comes after the pilot validates the feel. 每个单元训练课程中的一项思维技能。A 线 12 个单元已全部可用;B 线练习模式等试点验证手感后再做。

What practice mode does — and doesn't do. These exercises drill recognition — spotting a trick fast, picking the better question. They are auto-checked, so the answers are fixed. The deeper skill — writing your own reasoning, naming your own way to check a claim — lives in the full lessons with a facilitator. Practice mode is the warm-up, not the whole gym. 练习模式能做什么——不能做什么。 这些练习训练的是识别能力——快速发现把戏、挑出更好的问题。它们由系统自动批改, 因此答案是固定的。更深层的技能——写出你自己的推理、说出你自己核实某个说法的方法—— 存在于由教师带领的完整课程中。练习模式是热身,而不是整个健身房。
