【hypothesis】Classically a prediction derived from a theory,such that if the prediction itself proves false then the theory must be questioned.For example,if a learning theory predicts that language learners will benefit more from uncontrolled practice than from controlled practice with grammatical explanations,we can therefore hypothesize,for the sake of an experiment,that a given group of learners will make significantly more practical linguistic progress engaging in uncontrolled practice than a parallel group engaging in controlled practice with grammatical explanations.If this result is not obtained,then the original learning theory will need to be re-examined.
