The term Lehrstücke, or learning-plays, describes a series of experimental works written in the 1920s and early 1930s by Bertolt Brecht and a number of collaborators, including Kurt Weill, Hanns Eisler and Elisabeth Hauptmann. The intention behind writing and performing these experimental plays was not necessarily to culminate in a finished, final product to be replicated exactly during each performance. Rather, the ideal Lehrstück performance is also something of a rehearsal, or, as Frederic Jameson (1998) describes it, "one continuous master class" (p. 62-63). Jameson suggests that the process of acting in a Lehrstück is the end result: "the decision to act out this particular gesture; or not to act it out, or to act out its opposite-now proves to be the annulment of difference on another, and perhaps even more basic, one: namely, that between actors and public" (p. 65). As performer and audience are synthesized, this opens up a new realm of possibilities for action and choice within the framework of the play.In experimenting with the fundamental dynamics of the stage through the Lehrstück, Brecht dissolves the difference between player and spectator, and instead advocates a "große Pädagogik" which "only recognizes actors who are simultaneously students" (Brecht, 2003, p. 88). Whereas difference is eradicated in terms of actor/spectator, it is highlighted in the potentials open to the characters within the world of the drama. In focusing not on one final product, but rather on the process of artistic development as in a rehearsal, the Lehrstück aims to bring about a kind of self-realization in those taking part. Brecht suggested that "[t]hese experiments were theatrical performances meant not so much for the spectator as for those who were engaged in the performance. It was, so to speak, art for the producer, not art for the consumer" (Brecht, 1964, p. 80). As this essay explains through an examination of the process and development of the 1930-31 Lehrstücke for young audiences, Der Jasager (He Who Says Yes or, He Said Yes) and Der Neinsager (He Who Says No or, He Said No), audience members were empowered as they became engaged in the process of production. As such, Brecht's Lehrstück-theory can be useful to both practitioners of theatre for young audiences and its scholarly community.While children factor into Brecht's ideas on pedagogy and theatre, the Lehrstücke are not traditionally thought of as children's theatre; only Der Jasager and Der Neinsager were written for young people. Much of Brecht's Lehrstück-theory deals with adult participants, both as performers and audience members, yet these ideas
