Learning vs acquiring: How learning grammar can change everything

Learning vs acquiring: How learning grammar can change everything
Stephen Krashen, a renowned linguist and educational researcher, developed several hypotheses related to second language acquisition. His theories emphasize the importance of comprehensible input and natural language acquisition over explicit grammar instruction. However, learning grammar can still play a role in language learning. Below is an overview of Krashen’s hypotheses and how learning grammar may complement his theories:
Krashen’s Hypotheses
1. The Acquisition-Learning Hypothesis
Krashen distinguishes between acquisition (a subconscious process similar to how children learn their first language) and learning (a conscious process that involves studying grammar rules).
He argues that acquisition is the primary way people become fluent, while learning has a limited role.
2. The Natural Order Hypothesis
Learners acquire grammatical structures in a predictable order, regardless of explicit instruction.
Some grammar points are acquired earlier, while others come later.
3. The Monitor Hypothesis
Conscious learning (such as studying grammar rules) acts as a "monitor" or editor.
Learners use grammar knowledge to refine their speech or writing when they have time to do so, but it does not drive fluency.
4. The Input Hypothesis
Language acquisition occurs when learners receive comprehensible input-language that is slightly beyond their current level.
Instead of focusing on grammar, learners should be exposed to meaningful language in context.
5. The Affective Filter Hypothesis
Emotions such as anxiety, motivation, and confidence affect language acquisition.
Stressful environments that focus too much on grammar rules can hinder learning.
The Role of Learning Grammar in Language Acquisition
Although Krashen downplays the role of explicit grammar instruction, it can still be beneficial in certain ways:
Enhances accuracy - While grammar alone does not lead to fluency, it helps learners refine their speech and writing.
Supports writing skills - In academic and professional settings, formal grammar knowledge is often required.
Aids in understanding complex structures - Some advanced grammatical concepts are difficult to acquire naturally, so explicit instruction can clarify them.
Boosts confidence - Some learners feel more comfortable speaking when they understand grammatical rules.
Balancing Krashen’s Approach with Grammar Learning
Prioritize comprehensible input - Exposure to real-life conversations, books, and media should be the main focus.
Use grammar as a tool, not a goal - Grammar should support communication rather than be the main focus.
Encourage meaningful communication - Instead of memorizing rules, learners should apply grammar naturally through speaking and writing.
In summary, Krashen's hypotheses suggest that natural acquisition through exposure is key to fluency, but explicit grammar learning can still support accuracy and confidence in language learners. The best approach is a balance between meaningful input and occasional grammar study.
