“…There are several works on the effectiveness of YT in terms of improving different language skills, such as vocabulary acquisition (Hakim, 2019;Heriyanto, 2015;Kabooha & Elyas, 2018), speaking (Riswandi, 2016;Watkins & Wilkins, 2011), listening (Saputra & Fatimah, 2018;Watkins & Wilkins, 2011), writing (Mayora, 2009;Watkins & Wilkins, 2011), reading (Watkins & Wilkins, 2011), or pronunciation (Watkins & Wilkins, 2011). However, other studies point out some disadvantages, such as lack of motivation to use this website as a medium to study English outside of class and develop some degree of autonomy (Kelsen, 2009); poor sound quality, pronunciation mistakes, and slang language (Ghasemi et al, 2011); low writing performance (Styati, 2016); or the fact that schools may have blocked the YT website because students might use it for non-educational purposes (Alhamami, 2013).…”
