EFL STUDENTS STRATEGIES IN OVERCOMING SPEAKING DIFFICULTIES
Kata Kunci:
EFL students, speaking difficulties, strategies, overcoming,Abstrak
Students often encounter various difficulties when it comes to speaking, particularly in second language acquisition or public speaking situations. One common challenge is the lack of vocabulary and language fluency, which hampers their ability to express themselves effectively. Students may struggle to find the right words or phrases to convey their thoughts, leading to hesitation and a lack of coherence in their speech. Pronunciation issues can also impede communication, as students may find it challenging to accurately articulate sounds or stress patterns. Additionally, anxiety and self-consciousness can hinder students' speaking skills, causing nervousness, fear of making mistakes, and a reluctance to engage in conversations. Overcoming these difficulties often requires targeted instruction, practice, and a supportive learning environment that encourages students to take risks and develop their speaking abilities.
