The OER is constantly updating and adding new articles and materials. I recently came across several that I hadn’t realized existed, as they are included in other courses. For example, "Growth of Cities" offers an intriguing exploration of various ancient cities, introducing concepts such as social hierarchies, urban poetry, trade networks, and the rural-urban divide. I plan to introduce this article to my students because of its clear presentation of concepts and the variety of examples it provides. Have you used it? If so, what activities do you assign to students after they read it? Do you use the three close reading technique? Andrea Wong
