Within the growing field of publications on El Sistema and Sistema-inspired programmes around the world, a marked divide can be observed between the findings of critical academic studies and commissioned evaluations. Using evaluations of El Sistema in Venezuela and Aotearoa New Zealand as our principal case studies, we argue that this gulf can be explained at least partly by methodological problems in the way that some evaluations are carried out. We conclude that many Sistema evaluations display an alignment with advocacy rather than explorative research, and that the foundation for El Sistema's claims of social transformation is thus weak.

谁看守望者？评估 El Sistema 的评价

在世界各地关于 El Sistema 和受 Sistema 启发的计划的出版物不断增长的领域中，可以观察到批判性学术研究的结果和委托评估的结果之间存在显着差异。使用对委内瑞拉和新西兰奥特罗瓦的 El Sistema 的评估作为我们的主要案例研究，我们认为，这种鸿沟至少部分可以通过某些评估的方法问题来解释。我们得出的结论是，许多 Sistema 评估显示出与倡导而非探索性研究的一致性，因此 El Sistema 声称的社会转型的基础很薄弱。
