LITERATURE REVIEW
Vocabulary Acquisition in Second Language Learning Vocabulary is central to second language proficiency
because it supports comprehension, expression, and overall communication (Nation, 2013; Webb & Nation,
2017). Learners typically gain receptive understanding before developing productive use, yet long term
retention remains a challenge when words are learned in isolation (Schmitt, 2008). Traditional approaches such
as memorisation and translation exercises promote only surface recall and often fail to create meaningful
associations. Research consistently shows that repeated exposure and use of words in authentic communicative
contexts are crucial for consolidation and retrieval (Webb & Nation, 2017). In other words, vocabulary
learning is strengthened when it is embedded in purposeful tasks that require interaction and understanding
rather than simple recall.
Gamification in Language Learning Gamification refers to the use of game elements in educational settings to
increase motivation and engagement (Deterding et al., 2011). Elements such as points, challenges, feedback,
and cooperation make learning more interactive and goal oriented. Studies have shown that gamified learning
environments enhance learner motivation and vocabulary acquisition by combining enjoyment with cognitive
effort (Reinhardt & Sykes, 2014; Liu, Lin, & Paas, 2020). Gamification also supports self-regulation and
persistence, which are essential for vocabulary growth. However, most existing research focuses on digital and
classroom-based implementations, leaving limited exploration of embodied, outdoor gamified activities that
merge physical and social engagement.
Embodied and Situated Learning Embodied cognition theory asserts that learning occurs through the body’s
interaction with the environment. Movement, gesture, and sensory experience activate cognitive processes that
make learning more memorable (Barsalou, 2008; Glenberg, Witt, & Metcalfe, 2011). Situated learning theory
complements this view by emphasising that knowledge is constructed through authentic participation in social
contexts (Lave & Wenger, 1991). Together, these perspectives provide a strong foundation for Vocabulary
Quest, where learners interact physically with language in meaningful, team-based situations. The combination
of embodiment and social context allows words to be linked with experiences, actions, and collaboration,
deepening understanding and recall.
Game-Based and Outdoor Learning
Game-based learning uses the structure of play to achieve educational goals through competition, problem
solving, and collaboration (Gee, 2005). Outdoor learning extends these principles beyond the classroom,
allowing learners to connect language with the environment. Studies show that learning outdoors increases
engagement, motivation, and memory retention by providing novelty and authenticity (Rickinson et al., 2004;
Tobin, 2021). Recent work also indicates that outdoor vocabulary activities improve contextual understanding
and promote active participation (Mariappan, 2025; Richardson, 2025). Despite these advantages, research in
higher education remains limited, highlighting the need for further empirical evidence.
Learner Engagement and Motivation
Engagement is a multifaceted concept involving behavioural, emotional, and cognitive dimensions (Deci &
Ryan, 2000; Dörnyei, 2001). Gamified and embodied activities sustain engagement by offering immediate
feedback, clear goals, and opportunities for collaboration (Landers, 2014). When learners are emotionally
invested, they are more likely to engage deeply with vocabulary, leading to improved retention. Studies by Su
and Cheng (2015) and Cheng (2025) show that learners often attribute successful word learning to enjoyment
and teamwork. These findings suggest that engagement functions both as a psychological condition and as a
mechanism for learning.
Research Gap and Objectives
Although many studies have demonstrated the benefits of gamification and digital learning, there remains a
lack of research on physically embodied, outdoor vocabulary activities at the tertiary level. Most studies are
