**Building a Swimmer: The Instructor's Approach**

In the chapter "Deep Water" from the Flamingo textbook of English Class 12, the instructor plays a crucial role in transforming Douglas into a swimmer. He follows a systematic and patient approach, which can be summarized as follows:

**1. Assessing Douglas's Fear:**
The instructor begins by understanding Douglas's fear of water. He observes Douglas's uneasiness and fear when it comes to swimming, and realizes that gaining his trust and building his confidence is essential.

**2. Creating a Safe Environment:**
To alleviate Douglas's fear, the instructor ensures a safe and comfortable learning environment. He chooses a shallow pool, where Douglas can stand, ensuring that he feels secure and in control throughout the learning process.

**3. Establishing Trust and Confidence:**
The instructor understands the importance of trust-building. He starts by holding Douglas's hands and gradually introduces him to the water, making sure Douglas feels supported and safe. The instructor's gentle and patient demeanor helps build Douglas's confidence and trust.

**4. Gradual Progression:**
Recognizing that Douglas's fear cannot be overcome instantly, the instructor takes small steps to help him develop swimming skills. He begins by teaching him to float, assuring him that water can support his body weight. This step-by-step approach helps Douglas gain confidence in the water.

**5. Encouragement and Motivation:**
Throughout the learning process, the instructor keeps Douglas motivated by providing constant encouragement. He praises Douglas for every small achievement, reinforcing his progress and boosting his self-esteem. This positive reinforcement helps Douglas overcome his fear and continue learning.

**6. Teaching Techniques:**
The instructor employs various teaching techniques to build Douglas's swimming skills. He demonstrates different strokes, such as the breaststroke, and explains the movements involved. Through repetition and practice, Douglas gradually learns and improves his swimming technique.

**7. Patience and Support:**
The instructor remains patient and understanding throughout the learning process. He understands that overcoming fear takes time and provides the necessary support and guidance to Douglas. His empathy and understanding help Douglas feel comfortable and motivated to learn.

In conclusion, the instructor's approach to building a swimmer out of Douglas involves understanding his fear, creating a safe environment, establishing trust and confidence, gradual progression, encouragement, teaching techniques, patience, and support. This comprehensive approach leads to Douglas overcoming his fear of water and becoming a confident swimmer.
