A couple of decades ago, there was only one place to watch a movie: Film theater or talkies. You have to wait until the release of movie usually on Friday, go to the theater buy ticket and watch the movie. Theaters had fixed and regular times for shows.
About a decade or so ago, things started changing. Introduction of CD allowed people to watch movies at places and times of their convenience such as at home and in the evening- provided they can afford CD player. Some time later Cd rental opened up movie watch opportunities ti many more on weekdays- in office- in functions and in bus during travels or in hotels during stay. In other words theater gradually lost the primary position as the place for watching movies.
Something similar has happened or happening to class room teaching and learning. While I was studying in school during 1970's, it was classroom where most or even all learning and teaching happened. if someone missed class for whatever reason, there was not second chance or any other resources to reply upon except a friendly classmate's notes or help. Things started changing slowly in late 1980's and rapidly in 90's. Learning was never confined to classroom only. Alternatives became available: tuition classes, guides, notes, coaching classes, summer coaching centers and so on. The appeal and popularity of these and other avenues for learning alternatives so much so that most students practically forced to avail or subscribe one and many time more of such services. My daughter who is appearing for X standard exam this year has many resources including exam recokner.
Because of these classroom proceedings today are so boring for students that they hate it.
With such kind of learning environment for well over 12 years or so, today students enter professional courses such as engineering or medicine or management. They find it hard to orient themselves for classroom learning.
