These studies inform Route L2’s design; they did not directly evaluate the game.
Noticing and Attention to Form
What the research suggests
Schmidt (1990) argued that noticing plays a central role in turning language input into intake—the portion of input that becomes available for learning. In a study with beginning adult learners of Spanish, greater awareness of target forms was associated with better recognition of those forms (Leow, 1997). In a computerized problem-solving study with adult learners of Spanish, more explicit learning conditions were associated with greater awareness, and greater awareness was associated with stronger recognition and production of new examples immediately and over time (Rosa & Leow, 2004).
How Route L2 applies it
Much of Route L2’s core practice draws attention to meaningful endings and other form contrasts by presenting them as short choices and then displaying the completed form after each answer. This gives students repeated opportunities to notice, compare, and select the form that fits each prompt during play.
Repeated Practice and Skill Development
What the research suggests
Knowing a grammar rule is different from applying it accurately during a task. Presson et al. (2013) found that beginning and intermediate learners improved their production of Spanish present- and preterite-tense forms after web-based practice with corrective feedback. Improvement extended to untrained verbs; for beginning learners, gains remained evident 18 weeks later relative to an untrained comparison group. Dracos and Henry (2018) likewise found that multisession, task-essential practice led learners to rely more on person and tense information in Spanish verb endings during sentence interpretation.
Computer-delivered correction provides additional support for this design. Sagarra and Abbuhl (2013) found that computer-delivered recasts—which supplied the target Spanish form after noun–adjective gender and number errors—led beginning learners to produce more target-like forms and repair more errors than a simple error signal or no feedback.
How Route L2 applies it
In its official question banks, Route L2 revisits target grammatical contrasts through short, varied prompts. It immediately displays the completed correct form after each answer and uses a sound to confirm whether the response was right or wrong. A missed item is scheduled to return after several intervening questions if play continues. Students therefore have repeated opportunities to notice the form, check their choice, and try the distinction again.
Game-Based Learning and Engagement
What the research suggests
A systematic review of 26 studies involving second-language learners ages 6–18 found that digital learning games may support language learning, learners’ attitudes, emotional responses, and participation. Across the reviewed studies, the authors repeatedly highlighted appropriate challenge, feedback, clear goals, learner autonomy, interactivity, and ease of use as influential design features (Acquah & Katz, 2020).
After eight weeks of game-like activities using a grammar-focused mobile application, 82 university learners of Spanish reported increases in enjoyment, intrinsic goal orientation, perceived control of learning, and self-efficacy, and they evaluated the activities positively (Cho & Castañeda, 2019). These findings are consistent with purposeful game-like activities as one way to encourage engagement with Spanish grammar practice.
How Route L2 applies it
Route L2 connects each grammar choice to visible progress in a race: correct answers accelerate the Route L2 chiva—the game’s colorful bus—while incorrect answers slow it down and reveal the correct form. Short rounds, visible progress, and classroom races are intended to sustain participation and repeated practice as part of broader instruction.
