In the past, input in language learning meant any exposure to the new language, like hearing or reading it. Teachers usually used input to explain grammar rules and then made students practice speaking or writing. VanPatten and Cadierno (1993) explained that real input should be meaningful language—sentences that give information and help learners understand meaning, not just grammar.

VanPatten’s Principles of Input Processing (2002) show that learners focus on meaning first and form later. They notice words like nouns and verbs before small grammar endings. Learners also think the first noun in a sentence is the subject. Because of this, they often miss grammar details when listening or reading.

Processing Instruction (PI) is a teaching method based on these ideas. In PI, students don’t produce sentences but do activities that make them notice grammar while understanding meaning. For example, they listen or read and decide who does what in a sentence. Research shows that PI helps students understand and use grammar better because it changes how they process language in their minds.

Methods based on input type

Comprehensible Input: This is input that is slightly above your current level, making it understandable yet challenging. It's a core concept in language acquisition.

Modified Input: This includes techniques like simplification, which makes the language easier to understand, or elaboration, which provides more detail.

Structured Input Tasks: These tasks are designed so learners must rely on specific grammatical forms or vocabulary to understand the meaning, helping them to focus on and learn those structures.

Enhanced Input: This involves highlighting or emphasizing specific elements in the input, such as using bold text or a different tone of voice, to help learners notice them.

Traditionally, input refers to the language exposure learners receive, seen as the essential raw material for acquisition. In classrooms, input comes from listening, reading, and interaction with teachers or peers. The prevailing assumption is that comprehensible input — language just beyond the learner’s current level — naturally leads to internalization of words, grammar, and structures

Looking at VanPatten & Cadierno and VanPatten, first review the traditional concept of “input” in language acquisition and the language classroom. Take time to explore VanPatten’s “Principles of Input Processing” (Table 1). Discuss the degree to which you have observed these principles either in yourself learning a language or in language learners. Then describe what is meant by “processing instruction” (PI)
