Krashen's theory includes five axioms about second language acquisition: 1) Students acquire new vocabulary comprehensively, 2) Students produce basic comprehension, 3) Students begin with phrases and statements, 4) Students use more complex statements, and 5) Students develop specialized vocabulary and grammar. The theory also includes processes like the strategic process of analyzing ideas, the affective-humanistic process, and supporting processes like dialogues and charts. Some example activities are designed to build motivation through value, self-efficacy, and attributions by having students listen to experiences, work with grammar, and organize language tasks.
