In a language class, encouraging students' willingness to communicate (WTC) using the target language is essential, as it is a good signal whether or not the language has been successfully acquired. Given the importance of students' willingness to communicate in English class, the 2013 national education curriculum promotes students' oral communication skills, including in foreign languages, particularly English. The present study aims at investigating students' WTC in English classes. It examines the patterns of WTC patterns employed by Indonesian students in class. Drawing from close observation on two English classes at a junior high school in Aceh Timur, findings reveal that different task types lead to different patterns of WTC. It pedagogically implies the need to provide varied tasks and activities in order to increase students' engagement and varieties of their WTC patterns.
