Scholarships and bursaries that help students with extra tuition classes are lifesavers for some families. Some students have the brains and are smart enough to do the research, but just need a little help to get their ideas down on paper if for example English isn't their second language. Some countries/organisations require a commitment from the student to take English lessons as well.
Perhaps it depends on who is paying for these classes. Students often don't work as hard when it is someone else's money they are wasting since there isn't much of a sense of ownership. That is especially true if a student never intended to go to school in the first place, but finds himself or herself attending school on scholarship or on some quota program where so many women or so many minorities have to be accepted for the the university or college to be kept out of trouble. In my experience, I've heard several comments in the Registrar's line where a student is yelling across the room to someone else about being "on probration for grades, but I have one more semester to party!" In those cases, I don't think if matters one bit to the student about those classes or the grades.
On the other hand, those students who are working to put themselves through school are killing themselves to make the grades. The ones on scholarship or grants who worked very hard to receive those honors also work very hard and appreciate what they've got since allowing GPA to drop often means the money drops, too. In many cases, students can only attend college if there is scholarship money or if they work a full-time job at the same time. Those students know what they want, and they do what it takes to get it.
I think it depends on the student and their willingness to participate in the learning. If the student is not interested in learning it will not matter what kind of class they are in. The students I have worked with even in one to one settings have to have a desire to start learning. It has to be their own desire not that of their parents or anyone else.
I thought perhaps the author was talking about classes where you have to pay--like college classes or private schools as opposed to public education. Theoretically they would be more productive academically because not only is education at stake, but money is too.
This gives rise to an interesting question. If parents of students who fail public school classes (due to well documented lack of effort) had to pay the tuition for that student to repeat the class, would more parents be motivated to make their kids be engaged and productive in class?
This is an interesting question. First, there are a lot of variable that one needs to define and limit the essay to a specific area, or else things will be unmanageable. For instance, you can write a good essay on the merits and differences between private school (where you certainly pay tuition) and public school (where there is no tuition). If you were to do this route, you could create a great thesis. I would say that "generally" private schools are better, because they have smaller classes (not everyone can afford a private school education), teachers are usually better (since these school want the best teachers possible and have the money to hire them), and parents have more time to help or get tutors to help (since they have more money).
Presuming the same lines as the first response, tuition classes being small group or one on one help in addition to regular classes, I think they have the potential to help students. I say "have the potential" because it really falls to the student wanting to be there and putting in the work. A tutor/teacher can give students guidelines, formulas, and tools to improve their skill set in any discipline, however it is the active application of these by the student that results in success. The one on one attention allows a teacher to focus his or her style to that student's learning, whether it be visual/audio/kinetic/etc. This specialized teaching is ideal for students. If a student has a certain learning style and a teacher taps into that and uses that mode as the primary teaching style, learning is optimal. Think of the teaching style being a certain key and the student's learning style being a lock. If they match up perfectly, the lock opens: the student's abilit to learn information is vastly great than it would be if being in a general style in a large classroom.
I presume that here you are talking about extra tuition classes for students (such as one to one sessions) where students can focus in on their studies more deeply with a dedicated personal tutor? Certanily, if so, this would help certain kinds of students to achieve their best. For example, for some students, although they know their research very well it may be that English is not their first language. They may need support in expressing themselves more articulately - or even in interpreting the unique colloquilaisms of a set text. Obviously, the tutor cannot write the essays for the student, but extra help with languages such as English can only benefit the learning process - especially with getting the student's own knowledge down onto the paper.
I would have to believe that tuition classes that are paid for by the students themselves would have a far greater benefit in relation to the student completing and his making an extra effort to do well in the class. However, if the student's tuition is paid for by parents the emphasis is a bit less likely. This being said, I do not feel this is the case in all scenarios.
In looking at the student who pays for his won tuition, he has even more to lose if he is unsuccessful in his class. He had worked hard to earn the money which took his time and income away from leisure activities. He would loose the benefit that he hopes to gain by concluding the class and gaining a positive grade. In addition, he would have wasted his time and money. Therefore, I believe having made the investment in his own education is more likely to inspire his success.
