Give students a conversation topic at the end of the class to talk about. Be sure it integrates the newly taught structure, or ask students to use the new structure as they speak. You can find conversation topics from current events, magazines or Spanish newspapers. Make the topic controversial to keep students interested and to get even the shiest of students to talk.
Bring a Spanish song or audio book to class that uses the new vocabulary or structures taught. Students can see how the new structure is used in real language situations through this type of activity. Give students the lyrics or audio transcript and ask them to note where the structure is used and how it is used. If you use a song, get students to participate even further by singing the song.
Add video content to your classes through small videos you create or use movies for more advanced students. Film a conversation in a restaurant, store or on the street. Upload the video to Youtube or record on a DVD. Introduce new vocabulary before watching the video. Play movies or historical documentaries for more advanced students. Ask students to use the vocabulary demonstrated in the video.
Play games in the classroom to integrate the newly taught structures. Integrate role playing games, or games like Tic Tac Toe, Hangman, Jeopardy or any other language game. Many of the language games played in teaching ESL can be adapted for use in the Spanish language setting.
