I think that we, here in the UK, have the resources in today's age to teach robust and in-depth courses that will produce thinkers and Ullama who have both eyes open; they know and understand the Islamic Sciences thoroughly and they also understand the Western or secular way of life as well as imploring skills that will benefit them in the West and help them navigate their way through it and, hopefully, to others in the propagation of the Deen.
In my opinion, the Islamic teaching needs to be of a very high level, up to Ifta Level Studies for those who are looking to teach or work for the Deen, but, what is just a important, especially today, is building competency in the students and this can be done by working on their communication skills, reasoning skills, critical thinking and increasing their general knowledge and understanding of science and so on.
I say the above because unfortunately sometimes when our scholars have completed their education they seem and feel out-of-touch with the rest of society. If they are not out of touch with the outside world then their purpose will be better served, thus why I believe our courses should aim to produce scholars who are no longer narrow minded or oblivious to society's status...
In terms of a syllabus or course layout, I'm also a strong advocate of the traditional Dars Nizami system and it is my opinion that it should be taught in the UK more. However, I believe that it should be inclusive of other subjects and the course should include seminars from guest lecturers and professionals from other fields and also hold workshops, to broaden the students' mindsets and, again, prevent tunnel-vision, narrow minded and ill-informed scholars.
