It appears the original intentions for usablity of this Web site meets the goals it was designed for and the intended audience. I think, it was designed with an intention to be "over-simplified" so as to lead students to resources like the Brain Dominance test and the Myers-Briggs preliminary quizzes and interpretations and to pique interest. I do not think it was the intention of the creators to make this a scientific resource, but one that can spark an interest for students about themselves, and to allow them to learn more about their learning styles and preferences. Often, this topic is something new college students have never really considered. I, like the author, teach an Academic Strategies course to first time college students, and the information they learn about their learning styles or preferences is often a real key to motivation and results in extending their approach to studiy habits. In this course, as in mine, the intention is not to provide an in-depth treamtment of understanding in detail of neuroscientific research and data. Taken from this viewpoint, and for the audiences intended this Web site is a great tool for new college students.
I found all the links working except for one. It was certainly easy to navigate, and not a busy looking site--defintely desgined for both the right and the left brains out there!
