A middle school science class that contains many ESL learners is taught collaboratively by the science teacher and the ESL teacher. The two teachers introduce the topic of earthquakes by leading a class discussion and creating on the chalkboard a semantic map. As an introductory activity, this strategy is helpful to ESL students primarily because it:
1) Allows them to practice their speaking and listening skills
2) Helps them understand the vocabulary related to earthquakes
3) Encourages them to participate in group discussions
4) Provides visual support for understanding the topic
