Im Rahmen des Beitrags werden Konzeptdialoge als Aufgabenformate für die Entwicklung gemeinsamer fachlich tragfähiger Erklärungen in einer heterogenen Lerngruppe zu einem naturwissenschaftlich-technischen Phänomen sowie als Erhebungsmethode zur Erfassung von Vorstellungen und Präkonzepten von Schüler*innen für den inklusiven Sachunterricht vorgestellt. Fortführend werden Konzeptdialoge sowohl als Aufgabenformate als auch als Erhebungsmethode für den Einsatz in der ersten Phase der Lehrer*innenbildung, angelehnt an die Reflexion Masterstudierender in einem modulbezogenen Projekt mit Konzeptdialogen zum Phänomen Kuchenbacken, diskutiert. Abstract In this article, concept dialogues are presented as task formats for the development of common, professionally viable explanations in a heterogeneous learning group about a scientific-technical phenomenon, as well as a survey method for recording students' conceptions and pre-conceptions for inclusive Sachunterricht. Further, conceptual dialogues are discussed both as task formats and as a data collection method for use in the first phase of teacher education, based on the reflections of Master's students in a module-related project with conceptual dialogues on the phenomenon of baking cakes., QfI - Qualifizierung für Inklusion.

Biomass crops are perceived as a feasible means to substitute sizeable amounts of fossil fuel in the future. A prospect of CO2 reduction (resp. CO2 neutrality) is credited to biomass fuels, and thus a potential contribution to mitigate climate change. Short rotation coppices (SRCs) with fast growing poplar and willow trees are an option for producing high yields of woody biomass, which is suitable for both energetic and material use. One negative effect that comes along with the establishment of SRC may be a decrease in groundwater recharge, because high rates of transpiration and interception are anticipated. Therefore, it is important to measure, analyze, and model the effects of SRC-planting on landscape water budgets. To analyze the effects on the water budget, a poplar SRC plot was studied by measuring hydrological parameters to be used in the hydrological model WaSim. Results reveal very low or even missing ground water recharge for SRC compared to agricultural land use or grassland, especially succeeding dry years. However, this strong effect on plot level is moderated on the larger spatial scale of catchment level, for which the modeling was also performed. In addition to water, nutrient fluxes and budgets were studied. Nitrogen is still a crucial issue in today’s agriculture. Intensive fertilization or increased applications of manure from concentrated livestock breeding are often leading to high loads of nitrate leaching, or enhanced N2O emissions to the atmosphere on arable crop fields. SRC or agroforestry systems on former crop land may offer an option to decrease such N losses, while simultaneously producing woody biomass. This is mainly due to the generally smaller N requirements of woody vegetation, which usually entail no need for any fertilization. The trees supply deep and permanent rooting systems, which can be regarded as a “safety net” to prevent nutrient leaching. Thus, SRC altogether can help to diminish N eutrophication. It is important to offer viable and attractive economic perspectives to farmers and other land managers besides of the potential ecological benefits of SRCs. For this reason, an integrated tool for scenario analysis was developed within the BEST project (“BEAST – Bio-Energy Allocation and Scenario Tool”). It combines ecological assessments with calculations of economic revenue as a basis for a participative regional dialog on sustainable land use and climate protection goals. Results show a substantial capacity for providing renewable energy from economically competitive arable SRC sites while generating ecological synergies. Open Access Publikationsfonds 2015 peerReviewed
