Students are becoming less prepared for tests. For seven out of ten university professors (68%), one of the main causes is a gradual loss of the habit of reading and studying university textbooks in their entirety, despite the fact that these are the most effective teaching tools (88%) and are frequently designated as mandatory (50%) and recommended (45%) for exam preparation. Only 17% of professors believe that the educational materials produced by publishers are frequently read today. Over the last three to five years, 83% of teachers have observed a shift in study methods, with fewer consultations of suggested or mandatory readings, a larger reliance on summary materials and summaries, and more difficulties in dealing with complex or lengthy texts. According to professors, the most commonly used materials are course presentations and slides (69%) and notes (52%). What was the result? Without textbooks, critical thinking and analytical abilities deteriorate. 68 percent of teachers believe that a lack of habit of reading and studying whole textbooks is the root cause of major concerns in students' preparation. The most frequently stated shortcomings are inadequate analytical and critical reasoning skills (41%), shallow knowledge of facts (28%), trouble connecting themes (24%), and a lack of comprehension of basic concepts (19%).
