This is an outstanding peace of information inded. The whole topic on Authentic Assessment has been adequately exhausted, well presented and the content easily comprehensible.
The author's approach to the topic was appropriate as the assumtions of each assessment type were stated as a launching pad for the presentation.
I have used the the authentic assessment tool some time ago in an exceptional education classroom in a high school and I can attest that students' enthusiam in the project just hit the roof. My students wre classified as being learning disabled, and from that expeience, I learnt from their engagement in the project that it is critically important for teachers to, at anytime in the teaching and learning process, identify whatever instructional strategy that will fully benefit them. Students with learning disabilities in particular, dislike monotony, especially if the learning tasks are so regimented and uninteresting. Authentic Assessments are, therefore, one sure way of getting them interested and engaged. Even though the author does not single out any category of learners as being the most appropriate beneficiaries of AA, I have course to believe that those with learning disabilities will benefit from it the most, if well handled.
I particularly like the author's emphasis on the need for a combination of the types of assessments. Of course, it couldn't be all about one or the other.
