除了采用面向对象的广泛支持，还有关于学习面向对象编程和设计的困难的报道。这表明，有必要完善对认知困难的研究，以便为更好地设计相应的教育提供指导方针。我们的研究结果涉及到面向对象设计的一般问题，特别是抽象的问题，其各种表现形式。基于学生的解决方案，我们提取了一个认知任务分析分类抽象和继承。我们讨论了我们的结果对对象导向教学和进一步需要的研究可能产生的影响。
Alongside the widespread support for adopting object orientation there are reports on difficulties in learning object oriented programming and design. This indicates the need for refining the research on cognitive difficulties in a way that will offer guidelines for better designing respective education. The presented findings of our study relate to general issues of object-oriented design and in particular to the abstraction issue with its various manifestations. Based on students' solutions we extracted a cognitive task analysis taxonomy regarding abstraction and inheritance. We discuss possible implications of our results for the teaching of object orientation and for further needed research.
