Passage: In the era of digital transformation, universities are increasingly adopting adaptive learning platforms to enhance student engagement. A recent pilot study at a mid-sized state university revealed that while 70% of participants reported higher satisfaction with personalized feedback loops, only 40% showed statistically significant improvements in final exam scores. The discrepancy suggests that motivation alone does not equate to mastery. Furthermore, the system's algorithm tends to prioritize speed over depth, often skipping foundational concepts if a student answers initial diagnostic questions correctly. This 'efficiency trap' can lead to knowledge gaps that surface later in complex problem-solving tasks. Educators argue that without human intervention to audit these automated pathways, the technology may inadvertently reinforce misconceptions rather than correcting them. Question: What is the primary concern raised by educators regarding the adaptive learning platform? A) Students are generally dissatisfied with the personalized feedback provided by the system. B) The algorithm's focus on speed may cause students to miss foundational concepts. C) The pilot study failed to demonstrate any increase in student engagement or motivation. D) Final exam scores dropped significantly for all participants using the platform.
