摘要: Throughout the last decade, increasing attention has been given to discontinuity phenomena of university students in mathematics during their transition from school university. We hypothesize that two transformations this period have played an important role: transformation character and learning strategies necessary at Following hypothesis, we will present a study analyzing comparing German textbooks upper secondary level level, respectively. assume both can be understood more deeply when examine way are designed. Hence, categorical system developed which focuses on criteria such as “development concepts”, “deduction theorems”, “proof” “tasks” well “motivation”, “structure visual representation”. This article presents framework discusses results feasibility studies conducted with different widely used levels.
