The \_\_\_\_ model of teaching follows a “I do it,” “We do it,” “You do it together,” and “You do it alone” sequence of instruction.

責任逐漸轉移模式（gradual release of responsibility）由 Pearson 與 Gallagher 提出，後經 Fisher 與 Frey 發展為包含教師示範（I do it）、引導教學（We do it）、合作學習（You do it together）與獨立練習（You do it alone）的教學流程，完全符合題幹描述。
