2001), the connection between vocabulary cognition and language use is reciprocal and
interdependent. Having a robust vocabulary facilitates proficient language usage, while
engaging in active language use fosters the development and growth of vocabulary
knowledge. Consequently, vocabulary acquisition is of paramount importance for those
learning English as a second language (ESL) or as a foreign language (EFL). It is also crucial
for all language abilities, including speaking, listening, reading, and writing (Nation &
Nation, 2001). Vocabulary acquisition is instrumental in unlocking all other language skills in
ESL/EFL learning. It fosters confidence, enables clear communication, and facilitates fluency
and deeper engagement with the language.
A well-developed vocabulary, both in scope and depth, is a strong predictor of academic
success (Dakhi & Fitria, 2019). Research consistently indicates a positive correlation between
vocabulary knowledge and academic achievement across various disciplines and educational
levels. The strength of vocabulary lies in its ability to facilitate comprehension,
communication, and higher-order thinking skills. A rich vocabulary enables students to
understand complex academic texts, express themselves effectively, and analyze information
critically. This equips them for success in academic discourse, problem-solving, and creative
exploration. Therefore, prioritizing vocabulary development through active learning is not
just an enriching exercise, but a strategic investment in academic achievement (Mayer, 2002).
The current situation shows that vocabulary learning might be done in various ways.
For instance, by using technology. Smart technology has brought us to the social media era
which leads us to do anything from social media. TikTok is an example of a well-known
technology today, based on data from statisca, in january 2024, TikTok users from Indonesia
has reached 126 million users. TikTok is utilized for educational as well as commercial and
recreational objectives. The instructors provide valuable insights based on their experience
and have a good influence on the viewers of their films (Rahmawati, Syafei, & Prasetiyanto,
2023).
Moreover, TikTok's expansive audience and aesthetically captivating content have been
recognized as a suitable platform for disseminating factual information and transforming
education (Maulida, Noviyanti, & Wahyunengsih, 2022). This channel affords learners
chances to encounter language and prevalent vocabulary and phrases, ultimately improving
vocabulary mastery and comprehension.
As is well known, the use of video in academic settings has numerous advantages,
including the potential to engage students in learning through video presentations by their
teachers. The deployment of videos can also facilitate the delivery of learning materials to
students by teachers. (Richard, E Mayor, 2002) TikTok is used to disseminate content for
educational purposes as well as for commercial and recreational objectives. Instructors
provide valuable insights based on their experience and exert a positive influence on the
viewers of their films. The definition of each new word that students learn may be more easily
visualized if all words were represented using images or videos. As (Rahmawati et al., 2023)
highlight, the utilization of educational videos enhances not only individuals' abilities but also
their creativity, motivation, and vocabulary. The use of video as a medium for language
learning realistically presents language, combining visual and audio elements. This can assist
young learners in comprehending vocabulary meanings and generating enthusiasm for
vocabulary acquisition. Therefore, it is necessary to abandon the idea that pupils may improve
