“…Therefore, it is uncertain how effective incidental vocabulary learning is for different types of multiword vocabulary units. Other studies suggest the importance of explicit vocabulary learning, which can be done through purposeful lessons and prepared materials (e.g., Kim, 2019;Koh, 2020;Seo, 2014) or vocabulary learning tools such as flashcards (e.g., Kaku, 2018;Nakata, 2020) or gap-fill activities (e.g., Strong & Boers, 2019;Strong & Leeming, 2024). However, most of the aforementioned vocabulary learning methods suggested tend to be single-mode tools, whereas more recent studies have suggested that online flashcards can be created to be multimodal, containing multiple choice questions (e.g., Takeda, 2023), writing exercises (e.g., Strong & Leeming, 2024), speaking and listening exercises (e.g., Spring & Takeda, 2023), and even video examples (e.g., Hamagami et al, 2024).…”
