This research aims to assess the importance of Extensive Reading (ER) in developing reading comprehension, vocabulary development, and speaking fluency among English as a Foreign Language (EFL) students at King Khalid University (KKU). Most EFL students appear to be under pressure and confront anxiety while acquiring English language competency in basic language skills. According to MacIntyre and Gardner (1994, p. 284), language anxiety is the "feeling of tension and apprehension" with language learning, including listening, speaking, and language comprehension. One thought of making language learning an enjoyable activity is to make language acquisition a natural process instead of a forced and external one. According to Day & Bamford (2002), the goal of ER is to help students become fluent, independent, and confident readers. ER encourages L2 learners to explore the English language independently, especially in an EFL environment. ER inherently encourages language acquisition by allowing students to read extensively in a relaxed and natural environment, thus developing the basic nuances of the language effortlessly. This approach is also referred as uninterrupted sustained silent reading (USSR). Two distinct groups of students, namely experimental and control groups, will participate in this study. The results will help measure the effect of ER on students' reading comprehension, vocabulary development and speaking fluency. The experimental group will practice effortless ER for almost 12 weeks. Students' performance in the assigned reading task, vocabulary development, and speaking proficiency will be analyzed using SPSS. Finally, the researchers will suggest efficient measures to implement ER as a teaching methodology at the English department, and will also encourage implementation of an ER club at the faculty of languages and translation, KKU.
