Azulejos is a collection of texts to read from the 14th - 21st centuries to prepare students for the AP test. It is focused on reading and writing. There are other resources such as images, audio and video, activity ideas, and assessments. Compared to other online textbooks, these resources seem very limited. There are not listening activities, speaking activities, etc. because the focus is reading and writing for the AP test. There are practice AP tests. Overall, I think a student would be pretty bored compared to some of the other dynamic online textbooks, but if all you want is practice for reading and writing for the AP test, then I guess this is great. This material is rich in content but poor in presentation. I mean, it fulfills its informative objective by offering a variety of texts appropriate to the level of preparation for the AP exam, however, its presentation is very poor to engage the student in its content. It would be an adequate resource for college students, but for High School I consider that it does not reach the necessary level to engage students as other materials of the same style do.
