Dewey's experiential learning pedagogy (that is, learning through experiences) comprises the learner actively participating in personal or authentic experiences to make meaning from it

(1) with a feeling of something amiss, a unique and particular doubtfulness; this feeling endures as a pervasive quality imbued in inquiry and serves as a kind of “guide” to subsequent phases. Next, because what is initially present is indeterminate, (2) a problem must be specifically formulated; problems do not preexist inquiry, as typically assumed.[28] Next, (3) a hypothesis is constructed, one which imaginatively utilizes both theoretical ideas and perceptual facts to forecast the possible consequences of various operations. Next, in phase (4), one reasons through the meanings involved in the hypothesis, sizing up the implications or possible contradictions involved; frequently, what is discovered here requires a return to an earlier phase (to reformulate the hypothesis or even the problem).[29] Finally, inquiry comes to a close with phase (5), acting to evaluate and test the hypothesis; here, it is revealed whether a proposed solution solves the problem, or to put it LTI’s terminology, whether inquiry has converted an “indeterminate situation” into a “determinate one”.
