The document summarizes a field study observation of a high school English class. The curriculum was found to use a vertical design, where topics are taught in increasing depth across grade levels. It was also learner-centered, with an active learning approach. Reporting helped build students' confidence. The summary also outlines how different subjects can be integrated horizontally in grammar lessons, using examples from history, science, art, and literature. Finally, it analyzes aspects of the curriculum that could be modified to address issues such as non-readers, by reducing topics and increasing time for core subjects in early grades.
