Every CALL class made me open my eyes in computer areas. Most of them could be so helpful in my future classes at school. More specifically 'quizelet' is a useful tool to introduce vocabulary to the students in a more interesting way. 'VOKI' and 'Voicethread' are so exciting. I can use these sites to cover reading passages in class. These days students want more freshing and updated learning tools. And they want more visual stuff in class. So Call stuff can meet their demand.
