This systematic review of literature examines the effectiveness of blended learning programs in the instruction of the English language in Saudi universities. The aim of this review is to critically analyse current studies on the efficacy of BL programs in teaching English language courses in Saudi universities. The review draws attention to impact of blended learning models on English education in Saudi universities and offers insight on how to enhance the use of these models in English language instruction at the tertiary level. Seven research databases were searched, generating 132 studies. Studies published before 2010, not written in English, non-peer reviewed, non-journal, not evidence-based, without abstracts, non-BL focused, and not focused on English learning or university education were excluded, leaving 56 full articles which were then coded based on the data type they presented. The coding model employed was inductively formulated based on a preliminary review of the articles selected together with the most frequent groupings and hence no specific theoretical model guided the process. For each respective coding group, the number of articles that showed BL models were more effective in teaching English courses in Saudi universities was added to the number of articles that showed the approach led to better English language outcomes. The total number of the articles whose findings did not precisely indicate the effectiveness of BL was also obtained. Results show a significant proportion of the studies suggested BL programs positively affected English language learning in Saudi universities. This is evidenced by significant improvements in language skills and the general course learning outcomes.
