Motivation has long been identified as one of the main factors affecting English language learning (Gardner, 1985). This study examined the type and level of English language learning motivation ( instrumental or integrative) of 30 first-year undergraduate students at an international institute of engineering and technology in Thailand. A modified motivational survey of 20 items adapted from Gardner’s Attitude/ Motivation Test Battery (AMTB) was conducted. The data were analyzed by means of frequency, percentage, arithmetic mean and standard deviation. The main findings show that the students are relatively “highly” motivated and found to be slightly more “instrumentally” motivated to learn English. This reveals that instrumental motivation is a significant factor among this group of students learning English. Based on this study’s findings, some relevant and useful motivational learning implications are recommended for enhancement and improvement of the students’ motivation. Relevant language improvement programs and activities are also discussed in accordance with the students’ language difficulties as communicated in the open-ended questions to increase their motivation in English language learning.
