Education is about freedom and the medium of educating people plays a pivotal role in empowering them to move beyond conditions of oppression and control to that of liberty and development. In other words, the ability of individuals in a linguistic society to engage in reflection and dialogue in a common language goes a long way in liberating and empowering the citizenry for national development. Pedagogical roles of the English language worldwide, are contributing to global emancipation through increasingly participation and sharing of information and knowledge across the globe. The multilingual nature of the Nigerian community makes the choice of English as a medium of expression pertinent because it helps to facilitate contacts among Nigerians of diverse language backgrounds and cultures: thus, helping to create unity among the Nigerian people. Apart from being a language of expression, the Federal Government of Nigeria has specific pronouncements on the importance of English as a medium of instruction in the Nation’s educational system. The National Policy on Education (1997, Reviewed 1981), stipulates that in the lower primary school, the medium of instruction should be pupils’ mother tongue or the language of the immediate environment and that in the secondary school, every Nigerian child should learn one of the three major languages in addition to his or her mother tongue. In the Junior Secondary, the child is taught the English language and two Nigerian languages as school subjects while in the senior secondary school, the child is taught English and one Nigerian language also as school subjects. However, the English language still remains the medium of instruction at the upper primary to the tertiary levels. It should be noted that the quality of education handed to a child is in a wide sense determined by his/her level of acquisition of the language of education and expression. With the advent of Information and Communication Technology (ICT) the language is really playing the emancipation role by exposing students and other users of the language to the international world, thereby taking them from the world of obscurity to that of social, political, economic and technological enlightenment and development. This study adopted a descriptive survey research design of ex-post facto type. Self- made instruments were developed and samples were selected for the study. Emancipation role of English as a Language of Education and Emancipation role of English as a Language of communication are independent variables while national development is the dependent variable. The study population consisted of coordinate bilinguals in the Nigerian society. These are adult members who are proficient users of English Language as well as their Mother tongue. 100 bilinguals were sampled through quota (selection is based on definite characteristics. The characteristic is used to the researcher’s satisfaction) and snowball (used when the no of population is not known. One element/sample links to others) sampling techniques. Self-made questionnaire titled “EROELECQ” was adopted to gather information for the study. The questionnaire comprised two sections. Viz: background information and English language as a language of education and communication. The researchers with the assistance of two trained research assistants sought for the respondents and administered the instruments to them after explaining the study objectives to them individually. Data gathered from the respondents were analyzed through Pearson’s Product Moment Correlation (PPMC) to determine the significant relationship between emancipation role of English as a Language of education and communication as well as their impact on national development in Nigeria.
