This study observes a particular group of students learning medical terms (MT) implicitly through studying medical subjects. That is, based on the policy followed in the context of the study, students shall not receive any deliberate terms instruction. This paper investigates their experiences and attitudes towards acquiring MT in such a situation. Students’ acquisition and proficiency, hypothesizing a positive relationship between the two constructs, are self-assessed through pre- and post-test surveys. The surveys included 114 and 95 students in each phase, respectively. Prior to the surveys, focus group discussions were conducted, according to which the questionnaire was developed. A statistical correlational Pearson test was done to examine the relationship between students’ proficiency and incidental terms acquisition. The results indicated a significant negative relationship between the two constructs tested. The study also tested the effect of time on increasing acquisition through conducting a paired independent t-test between the two sets of data. The results found that a more extended period was significant to incidental acquisition. Overall, through comparing the means, modes, and medians in the two phases (pre- and post-test), the findings reveal an increase in the students’ terms acquisition volume. However, students seem not to favour the approach and still advocate explicit instruction for technical terms.This study observes a particular group of students learning medical terms (MT) implicitly through studying medical subjects.
