The individual study system in teaching general and agricultural economics: Methodology and results
介绍了瓦赫宁根农业大学在普通经济学和农业经济学课程中采用个人学习系统的经验，证明该方法能有效展示两门课程的联系，适合农业经济学学生。
General economics and, more particularly, agricultural economics can be fruitfully applied to the agricultural sector. Students of agricultural economics may benefit from knowledge of the general economic theory, not only because of the links between the theories, but also because of the growing interrelatedness of agriculture with the rest of the economy. Combination of these courses has the advantage of clearly showing these relations. Experience at Wageningen agricultural university proved that the Individual Study System is an appropriate form for these courses.
