Description: · Dewey seem to persuade men to teach a mode of learning and knowing which they themselves do not know and which they cannot grasp by their habitual ways of learning. Joseph Schwab · Pädagogik hat mit den Werdenden zu tun: mit den werdenden Menschen und - im Unterrich, als Didaktikk - mit dem Werden des Wissens in ihm. Martin Wagenschein · Læreren må møte og ta opp i sin undervisning elementer fra elevens verden utenfor skolen. Læreren må kunne improvisere. Læreren må forstå betydningen av å kunne opptre på en slik måte at innsikt fra posisjoner utenfor skolen nyttiggjøres i skolen. Asle Høgmo · Tact know no rules, yet tact is not unruly. .. Instead, tact is improvisational. Max van Manen · Unterrichtsplanung ... kan nie mehr als ein offener Entwurf sein, der den Lehrer zu … flexiblem Unterrichtshandeln befähigen soll. Der Massstab für die didaktische Qualität einer Unterrichtsplanung ist …ob die Planung dem Lehrer didaktisch begründbares, flexibles Handeln im Unterricht und den Schülern produktive Lernprzesse … ermöglichte. Dewey Square is a modern jazz standard, written by Charlie Parker in the late 1940ies. The proposal of this presentation is to look to jazz improvisation in general and to key institutions in the jazz world like the jam session for examples that might support investigation of professional improvisational competences also in the world of schooling and teaching. A recurrent motif is whether improvisation can be seen as a counterpoint to the focus on the pre-active preparation by teachers in theories of teaching and pedagogy, including in german and nordic didaktik/didaktikk. The quotes on top of the abstract indicate some of the keywords and scholars within the field of education that will be revisited in the seach for explicit or implicit reference to improvisation in relation to teaching and pedagogy. As a part of the transatlantic comparison of curriculum theory and didaktikk a number of researchers have focused on the key position of the professional teacher in the didactical tradition, and the understanding of teaching and teacher competences here will be compared with motifs from the jazz world like jamming, repertoire and standards, the professional flexibility that come from the sophisticated ability to play by ear. The presentation will be based on an article in norwegian that is to be published this year in a book on "Improvisasjon" ed. by Bjørn Alterhaug and Henning Sommerro and Ketil Steinsholt.
