This was justified by the view that reflective practice could help teachers to feel more intellectually involved in their role and work in teaching and enable them to cope with the paucity of scientific fact and the uncertainty of knowledge in the discipline of teaching.(TPO9, 45)

paucity /ˈpɔsɪti/ n.少量，少许，少数

This was justified (by the view) (that reflective practice could help teachers to feel more intellectually involved in their role and work in teaching and enable them to cope with the paucity of scientific fact and the uncertainty of knowledge in the discipline of teaching.)(TPO9, 45)

分析：

修饰一：(bythe view)，介词短语，修饰justified

中文：通过这个观点

修饰二：(that reflective practice could help teachers to feel more intellectually involved in their role and work in teaching and enable them to cope with the paucity of scientific fact and the uncertainty of knowledge in the discipline of teaching.)，超级无敌长的同位语从句，解释view的内容，在从句中还有一个并列结构A and B

中文：反思实践可以帮助教师带着更多思考去融入他们在教学中的角色和工作，并使他们能在教学法中处理科学事实的缺乏和知识的不确定。

参考翻译：托福课程

这是合理的，因为基于这样的观点：反思实践可以帮助教师带着更多思考去融入他们在教学中的角色和工作，并使他们能在教学法中处理科学事实的缺乏和知识的不确定。

这个句子的主要修饰成分就是介词短语和从句，大家务必想清楚，每一个修饰成分修饰的是什么，才能看清楚这个句子的结构。
