Abstract
There has been a dearth of studies exploring the development of online learning platforms in Indonesian ESP classes in recent years. To fill such a lacuna, the present study was designed to develop an online learning application for pharmacy students in their ESP learning in an Indonesian higher education setting. Encapsulated by Gall, Borg, and Gall's (2003) Research and Development (R&D) model, the study's findings showcase that (1) the application, named "Absyak," has been successfully developed at the design stage based on the needs analysis; (2) the variables of material, media, and student responses on learning have been validated and corrected according to the suggestions of two validators as media experts and three validators as material experts; (3) responses from 30 students showed that the indicators for each variable were valid, reliable, and very feasible to implement; and (4) the implementation phase with 60 students indicated that the developed material effectively enhanced the pharmacy students' English speaking skill. Implications from this study are offered at the end of this article.
