Abstract (eng)
In this master's thesis, the question of how activating the textbook tasks are with regard to the different operator levels in order to achieve the current curriculum objectives of geography and economic education lessons in the 7th grade of lower secondary school is answered. In addition, a second research question will be investigated to determine the extent to which the respective trends in the requirement areas of the tasks in the textbooks contribute to supporting successful internal differentiation. To investigate these questions, a quantitative textbook analysis is used to analyse the geography and economic education textbooks approved in Austria for the 7th grade of lower secondary school (as of the 2023/24 school year). With the new geography and economic education curriculum from 2023, the operationalised learning objectives of lower secondary level now include operators from all three requirement areas and thus fulfil the curriculum objectives of dealing with current and future social and environmental phenomena and developing these topics in a problem-solving manner. However, the previous curriculum is still visible in the approved textbooks for the 2023/24 school year, which is why the tasks in terms of operator levels strongly reflect the preference for requirement area I – reproduction and knowledge –. Similarly, despite the comprehensive operationalisation in the textbooks analysed, there are still tasks without operators. This and the increased use of tasks with only a low level of operators make qualitative internal differentiation during lessons more difficult. In order to support teachers with regard to internal differentiation with the help of tasks, it would be necessary to equalise the distribution of the operator levels used per curriculum topic in the textbooks or to create tasks with requirement level II and III operators more frequently.
