This diagnostic resource is designed to help students identify the text architecture of short passages and summarize their central ideas. Students are guided through understanding text structures such as 'Cause and Effect', 'Compare and Contrast', and 'Sequence (Order of Events)'. The resource includes several passages with corresponding questions aimed at assessing students' ability to label text structures, explain the main points, and evaluate their confidence in these skills. Through various exercises, this diagnostic promotes critical reading and comprehension skills necessary for effective analysis of texts.
