INTRODUCTION

            In today's globalized world, the ability to communicate effectively in English is more crucial than ever. For B2-level students, who are transitioning from basic proficiency to a more advanced understanding of the language, the acquisition of vocabulary plays a pivotal role in enhancing their communicative competence. Traditional methods of vocabulary teaching often fall short in providing the contextual richness that learners need to fully grasp and retain new words and phrases. (Brookfield, S. D., 2012)

This article aims to explore the potential of YouTube as a tool for teaching lexicon to B2-level students. By analyzing various channels and video types, we will identify how these authentic materials can be seamlessly integrated into lesson plans to enhance vocabulary retention, improve listening skills, and foster cultural awareness. Ultimately, this research seeks to provide educators with practical strategies for leveraging multimedia resources in the classroom, ensuring that students are not only learning words but are also able to use them meaningfully in their everyday lives.

METHODOLOGY

Using authentic materials from YouTube featuring scientists' opinions can significantly enhance vocabulary acquisition for B2-level students. This methodology not only fosters a deeper understanding of scientific language but also encourages critical thinking, creativity, and the ability to articulate complex ideas effectively. According to the Parker, W.C and Hess, D.E. the role of discussion in teaching and learning, emphasizing how engaging in dialogue promotes critical thinking, similar to case-based discussions. (Parker, W. C., & Hess, D. E., 2001)

Utilizing authentic literature-based materials from YouTube can significantly enhance vocabulary acquisition for B2-level students. This methodology not only fosters a deeper understanding of language but also encourages critical thinking, creativity, and cultural awareness through engaging literary content.

ANALYSIS AND DISCUSSION

Rationale for Using Authentic Materials

Real-World Context: Authentic materials like YouTube videos provide students with exposure to real-world language use, showcasing how vocabulary is applied in context. This enhances their understanding and retention of scientific terminology.

Engagement and Motivation: Videos featuring scientists discussing current research can captivate students' interest, making the learning process more engaging. The dynamic nature of video content can appeal to diverse learning styles.

Vocabulary Acquisition

Contextual Learning: By encountering vocabulary in context, students can better grasp meanings and nuances. This is particularly important for scientific lexicon, which often includes specialized terms that may not be encountered in everyday language.

 Repetition and Reinforcement: Repeated exposure to key terms throughout the video and subsequent discussions helps reinforce learning. Students are more likely to remember vocabulary they have actively engaged with rather than passively memorized.

Listening Skills Development

Active Listening: Watching videos requires students to practice active listening, a crucial skill in academic and professional settings. They learn to identify main ideas, supporting details, and the speaker’s tone.

 Diverse Accents and Speech Patterns: YouTube features a variety of speakers from different backgrounds, exposing students to various accents and speech patterns, which enhances their listening comprehension skills.

 Critical Thinking and Discussion

Analyzing Scientific Arguments: Engaging with scientists' opinions encourages students to think critically about the content. They learn to evaluate arguments, identify biases, and formulate their own opinions based on evidence.

Encouraging Dialogue: Group discussions following video viewings foster a collaborative learning environment. Students practice articulating their thoughts using new vocabulary, enhancing both their speaking and listening skills.

RESULTS

            The use of authentic materials from YouTube for teaching scientific lexicon to B2-level students resulted in significant gains in vocabulary retention, listening comprehension, and student engagement. While challenges were present, the overall impact was overwhelmingly positive, leading to a richer and more effective learning experience. Future iterations of this approach can build on these results by refining video selection and incorporating additional interactive elements. Using authentic YouTube materials for teaching scientific lexicon to B2-level students offers numerous benefits, including enhanced vocabulary acquisition, improved listening skills, and opportunities for critical thinking and discussion. While challenges exist, careful planning and implementation can lead to a rich and engaging learning experience that prepares students for real-world applications of their language skills.

            CONCLUSION

            The implementation of authentic materials from YouTube for teaching lexicon to B2-level students proved to be a highly effective approach. The use of engaging and relevant content not only enhanced vocabulary acquisition but also significantly improved listening comprehension and critical thinking skills. Students demonstrated increased retention of scientific terminology and developed a deeper understanding of concepts through contextual learning. Overall, this method has shown that integrating authentic resources can lead to a richer learning experience, encouraging students to connect language with real-world applications. Future teaching strategies can build on these findings by continuing to utilize diverse multimedia resources, further enhancing language learning outcomes for B2-level students.
