This study was performed to investigate the impact of the virtual classroom on second/foreign language (L2) interaction. A total of 90 Saudi female undergraduate students participated in this study. All participants were enrolled in an English language course in the Preparatory Year Programme (PYP) at a Saudi English Language Centre (ELC), with the English language being taught as a core module in this course. The English language proficiency level of the participants was equal to beginner or low intermediate, which was determined to be the A2 language level of the Common European Framework of Reference for Languages (CEFR). A quantitative research method, a questionnaire was developed with 19 statements to test the hypotheses of this study, which sought to determine whether virtual classes had an effective impact on language interaction and L2 learning, and whether participants had a positive attitude towards interaction and learning via virtual classes. The study revealed that there was a good degree of communication and interaction among Saudi students specifically in virtual classes. Also, participants showed a positive attitude towards using online classes for L2 learning. Thus, implementing virtual classes for language learning and teaching is highly recommend not only in this particular Saudi learning environment, but also across other EFL contexts. The study aspired to answer the following research questions:1. How effective are virtual classes for promoting interaction through the English language in the preparatory year in Saudi Arabia? 2. To what extent can Saudi students use virtual classes for learning English?
