Indonesian foreign language users (Bahasa Indonesia bagi Penutur Asing, BIPA) must juggle a wide array of different affixation patterns when working within Indonesian to create grammatical sentences. It has been shown that even at advanced levels, these affixation patterns remain an area of confusion when BIPA students produce languages (Nugraha, 2003; Suyitono, 2007; Defina, 2017; Riana, 2018). To address this issue a visual-spatial, gamified practice tool of several affixation patterns was created to support BIPA learners in their application of these forms. The tool’s design process was guided by the ADDIE framework and second language pedagogies like repetition, grammar in context, and interaction with language forms.

Usability was evaluated with three participants (n=3) through online and in-person synchronous sessions. Learning effectiveness was assessed using pre- and post-surveys and assessments with 15 participants (n=15). The usability study found general positive feedback and uncovered suggestions for several areas of improvement, such as adjusting the focus-content for repetition, ease of use with interactive elements across tech-tools, and clear bilingual (Indonesian and English) instructions. The learning effectiveness test indicated participants’ scores improved, and qualitative data from surveys showed mixed feedback on the structure and methodology of the learning tool. Where this tool was well received by intermediate to advanced learners, future work could focus on building in more support for beginning BIPA learners. Key takeaways include that the participant responses toward the gamified elements were split, and that iterative improvements based on user feedback are essential for optimizing this practice tool.
