Abstract: This researcher seeks to advance Thai university students’ English achievement through a greater understanding of the influence of ICT and its impact on students’ English language achievement, students’ participation within English classes and student attitudes towards learning English. This mixed method study was conducted using a pre-test, post-test design. Participants were 278 students attending a rural University in North-eastern Thailand, who were arranged into blended learning and face-to-face classes. A course web site was developed for course instruction. This site and social network tools such as Skype, Twitter and Facebook were utilised by the blended learning class for communications and language acquisition. Data was collected from the pre-test and post-test instruments, class room observation check lists, questionnaires, semi-structured interviews and researcher’s field notes in order to compare ICT blended instruction and traditional face to face instruction.
