Which hypothesis emphasizes the need for a positive classroom environment in language acquisition?

The Affective Filter Hypothesis is a concept introduced by Stephen Krashen, which posits that emotional factors can significantly influence a learner's ability to acquire a new language. This hypothesis highlights the importance of a positive classroom environment in fostering language acquisition. When students feel anxious, unmotivated, or self-conscious, their “affective filter” rises, which can impede their ability to take in language input and master new skills. Conversely, when students feel relaxed and encouraged, their affective filter lowers, allowing for better reception of the language input necessary for learning.

A supportive and engaging environment can enhance motivation and reduce anxiety, thereby facilitating more effective language learning. This understanding makes the Affective Filter Hypothesis central to creating effective teaching strategies and promoting successful language acquisition among learners.
