Abstract: The present investigation aims to investigate the factors that affect the teaching and learning processes of English teachers and learners at Thai Nguyen University. These factors were divided into two categories: socio-psychological (interest, personality family circumstances) and teaching situation (teachers and syllabus). Two sets of questionnaires were administered as the data collection instruments to gain enough data for the analysis. Results from both questionnaires show that social psychological factors influence the students’ attitude and motivation towards learning the English language.
