Critical digital literacy, the capacity to evaluate, question, and act on information encountered online, has become a necessary skill for second language learners, who increasingly meet their target language first through screens, algorithms, and unfamiliar digital norms rather than face-to-face interaction. This piece argues that second language acquisition (SLA) draws on many of the same cognitive processes that critical digital literacy requires, and that the language classroom is therefore a natural, if underused, site for cultivating it.
According to language development frameworks, acquiring a second language later in life draws on cognitive processes distinct from those used in first language acquisition, requiring greater involvement of metacognition, analysis, and pattern recognition. These are not incidental skills. They are also the building blocks of what Zagzebski (1996) and other virtue epistemologists would call intellectual virtue: the capacity to evaluate claims carefully, recognize one’s own assumptions, and revise belief in light of evidence. If SLA trains these capacities, it may also be training the specific dispositions that critical digital literacy depends on.
In Virtues of the Mind, Zagzebski (1996) examines how epistemic vocabulary, terms such as duty and obligation, is often borrowed from moral theory without much scrutiny of what that borrowing carries with it. Anscombe’s (1958) earlier argument, which Zagzebski’s project responds to, traces this vocabulary further still, to a law-like conception of ethics inherited from Judeo-Christian moral thought. The point, for language learners, is not theological. It is that acquiring a second language means encountering these inherited assumptions from the outside: a learner moving between languages notices that moral and evaluative terms do not translate cleanly, that “right” and “wrong” carry different weight in different linguistic systems. Recognizing this is itself a form of intellectual virtue, one that asks the same skepticism toward inherited categories that critical digital literacy asks of a reader navigating an unfamiliar platform’s norms.
This recontextualizing capacity does not stay confined to grammar and vocabulary. Acquiring a second language challenges learners to re-contextualize their ingrained assumptions and existing mental models, extending cognitive skills not as a one-time behavior but as a lifelong practice that builds guardrails directing cognition toward more virtuous modes of thought. That same capacity extends naturally into digital spaces, where learners are asked to evaluate unfamiliar norms, sources, and identities without the scaffolding of their first language or culture to fall back on.
Dörnyei’s (2005, 2009) concept of the ideal L2 self, one component of his broader L2 Motivational Self System, offers a useful cognitive framework for understanding this process: learner motivation is shaped by how learners picture themselves as future speakers and users of the language, an image increasingly built and rehearsed in digital spaces, through media, online communities, and self-directed practice. Bandura’s (1986) triadic model of reciprocal determinism describes how this happens: personal factors, behavior, and environment continuously shape one another, so a learner’s self-concept, the digital literacy practices they engage in, and the online spaces they inhabit form a mutually reinforcing loop rather than the simple two-way exchange it can appear to be at first glance. Practiced within this loop, critical digital literacy is not a separate skill layered onto language learning, rather it’s one of the things SLA is already training.
Second language acquisition, then, is not simply a linguistic exercise. It asks learners to notice their inherited assumptions, question unfamiliar norms, and build a self-concept as a user of new tools and systems, the same competencies critical digital literacy requires. Perhaps digital literacy instruction might see a more feasible path in deeper integration with SLA rather than attaching it onto overloaded curricula as a separate learning unit, another skill that one must acquire in order to perform a language.
