A simple yet effective tool for classroom learning; student-mentoring; counselling; planning.
At a personal-level I have had 'fantastic' results from students and individuals I've worked with in a mentoring-counselling capacity, more often leaving them to their own devices to create the detail.
A highly-effective revision tool for any student, particularly those preparing for exams, to arrange their thoughts in order and gain that ever-so-important visual perspective of their work.
