This WebQuest is highly recommended for ESL learners, especially for teenagers in their 4th year of E.S.O. or Bachillerato. Students will actively work on the creation of a tourist guide while they unconsciously develop their linguistic skills. They will discover the essence of a new city by exploring the arts, music and culture of the capital of England. This task-based activity is really motivating as it is oriented towards a real research. Students will learn to look for useful information and this will make them learn the English language by means of communication.
