To do this they must develop their hypothesis. Then researchers can develop a verbal and numerical hypothesis in which they will be able to test this hypothesis.

The Natural Approach and the Input Hypothesis emphasize unconscious acquisition by receiving comprehensible input. The Natural Approach is the method focusing on providing understandable spoken language known as comprehensible input and classroom atmosphere without anxiety.

If this comprehensible input is provided adequately‚ language acquisition progresses “naturally” (Larsen-Freeman)
