Unit2《Sailing the oceans》教学设计

（新人教版选修9）

Part One: Teaching Design Period 1: A sample lesson plan for reading (SAILING THE OCEANS) Teaching aims: To help students read about sailing the oceans

To help students learn about the predicate To guide the ss to talk about navigators and nautical instruments. Procedures Step1: ■Warming up by leaning about navigator

What is a navigator? A navigator is the person onboard a ship responsible for the navigation of the vessel. On aircraft, the position may also be referred to as a flight officer. The navigator's responsibilities include planning the journey, advising the captain (or pilot) while en route, and ensuring that hazards or obstacles are avoided. What is exploration? Exploration is the act of searching or traveling for the purpose of discovery, e.g. of unknown regions, including space (space exploration), or oil, gas, coal, ores, water (also known as prospecting), or information.

Exploration has existed as long as human beings, but its peak is seen as being during the Age of Exploration when European navigators travelled around the world.

In scientific research, exploration is one of three purposes of research (the other two being description and explanation). Exploration is the attempt to develop an initial, rough understanding of some phenomenon. Step2: ■Warming up by talking about Zheng He's Seven Voyages and other famous navigators. In July 11, 1405, the eunuch Zheng He of the Ming Dynasty royal court set out on his first overseas voyage. 初中数学、数学课件、数学综合练习题、数学教学教案、试卷数学

In the following 28 years, this navigator proceeded to carry out six more voyages, accompanied by a huge entourage of nearly 30,000 people. By traveling throughout Southeast Asia, and around the Indian Ocean to

the Red Sea and East Africa, he also landed at over thirty different nations.

He was the earliest largest scale navigation in world history, coming more than half a century earlier than Columbus'famous exploits... ■Talk about Marco Polo. Do you know this man? Yes, he is Marco Polo. Marco Polo (1254-1324), is probably the most famous Westerner traveled on the Silk Road. He excelled all the other travelers in his determination, his writing, and his influence. His journey through Asia lasted 24 years. He reached further than any of his predecessors, beyond Mongolia to China. He became a confidant of Kublai Khan (1214-1294). He traveled the whole of China and returned to tell the tale, which became the greatest travelogue. Step3:I. Pre-reading

What are navigational instruments?

●Navigational instruments were built in the age of exploration to guide the explorers to their destinations. ●navigational instrument - an instrument used for navigating

artificial horizon, flight indicator, gyro horizon - a navigational instrument based on a gyroscope; provides an artificial horizon for the pilot compass - navigational instrument for finding directions depth finder - navigational instrument used to measure the depth of a body of water (as by ultrasound or radar) inclinometer - an instrument showing the angle that an aircraft makes with the horizon instrument - a device that requires skill for proper use asdic, echo sounder, sonar - a measuring instrument that sends out an acoustic pulse in water and measures distances in terms of the time for the echo of the pulse to return; sonar is an acronym for sound navigation ranging; asdic is an acronym for anti-submarine detection investigation committee Step4: Read the passage and answer the following questions. 初中数学、数学课件、数学综合练习题、数学教学教案、试卷数学

1.What’s the main idea of the passage?

2.What is the use of a bearing circle,

astrolabe, quadrant or sextant?

What is the use of a compass? 3.Why are speed and time important in working out the longitude of a ship? 4. Why is the position of the sun and various stars useful for working out latitude? Step5:discussion Suppose you were a sea captain aiming to sail round Africa. Discuss in groups: What skills would you seek in your sailors? Step6：Consolidation Step7：homework
