Education really has changed in recent decades. My reasons for concluding this is true are many, varied, and too complicated to detail here. It is tempting to blame education for the changes in society that we observe, but that will gain us nothing and the blame is not deserved. All schools serve the learners who arrive at their doors (or at their learning management system in the case of online learners). They succeed with some and they fail with others; that has more to do with the variation of humans than it has to do with the faculty.
Schools reflect the society that creates them. Some of the turmoil attributed to schools in during the last decades of the 20th century and the first decades of the 21st century can be traced to the turmoil in society. The turmoil can also be attributed to changes in technology.
