| May 21, 2020 at 10:34 | comment | added | ACR | @YusufHasan, You are right, I cannot locate an online copy of his article. I had a scanned copy shared by a professor. The full citation is Gillespie, Ronald. "Chemistry–fact or fiction? Some reflections on the teaching of chemistry." Chemistry Canada 28.11 (1976): 23-8. | |
| May 21, 2020 at 10:29 | comment | added | Yusuf Hasan | @M.Farooq Can't find a link to the aforementioned work; can you provide me a source for "Chemistry: Fact or Fiction"? | |
| May 21, 2020 at 10:27 | comment | added | Knight wants Loong back | I agree with @M.Farooq, IIT JEE is a kind of smudge in the education system that needs to be stained off. No exam will ever want a student to memorise 50-100 without even knowing “where can we find vanadium for making $\ce{V_2O_5}$?”. | |
| May 21, 2020 at 10:20 | comment | added | Yusuf Hasan | @M. Farooq Ok,will definitely give it a whirl :) | |
| May 21, 2020 at 10:19 | comment | added | Yusuf Hasan | .... I am not abusing anyone,just stating what should have been the way to handle this situation | |
| May 21, 2020 at 10:17 | comment | added | Yusuf Hasan | @zombie You didn't get my point. I haven't used any slang; he did as he gave the reaction a made-up name RMR. Moreover,it is the duty of the teacher to teach the mechanism of the reaction along with the reaction equation(if a mechanism exists). If he doesn't do so, atleast he or she should state outright that a mechanistic pathway exists for this reaction,but we won't be covering it here. Stating a reaction outright as "Ratta Maar" (meaning rote memorization) when studies on mechanisms have been done is both incorrect as well as undermining to the scientists who have worked on the research.... | |
| May 21, 2020 at 10:14 | comment | added | ACR | @YusufHasan, If you are interested in why chemistry never attracts the best and the brightest, you should read "Chemistry: Fact or Fiction" by Gillespie from 1970s-yes the same person who came up with VSEPR theory. Despite being a 50 year article, the facts remain true today. | |
| May 21, 2020 at 10:12 | comment | added | ACR | @zombie, I am sorry but the coaching centers, the way they make the students cram for exams are curse in the education system. These systems can never create original thinkers. The same college teachers who are unable to teach in a govt. college become perfect instructors in coaching centers. Not all coaching centers are like that but a majority it. | |
| May 21, 2020 at 10:06 | comment | added | zombie | @Mr. Yusuf ; on my online video lecture my organic chemistry teacher told that we can convert benzene to phenol by using O2/V2O5 at 300⁰C which called ' RMR ' and he told its full name as Ratta Maar Reaction. Whatsever, we had not asked him anything he was just teaching the theory . So there is no cause to use any slang . You should not abuse any educator or any coaching centre like that. | |
| May 21, 2020 at 8:44 | comment | added | Yusuf Hasan | @Micelle Yeah,I know about Allen and such related cram schools(once prepared for such exams myself). And sadly,your point is very true; this reaction does have a mechanism as I have higlighted in the comments above,but if the teacher doesn't know it or isn't willing to teach it,he proclaims it as ratta maar. This creates a false impression about the nature of chemistry in high school students, and hence there questions are highly downvoted on SE. It's painful to watch as there questions receive negative ratings and are closed ultimately :( | |
| May 21, 2020 at 8:30 | comment | added | Micelle | Allen is a coaching institute for the JEE exams... You'll find many such "unexplained" phenomena in the coaching manuals. Half of the traffic on SE is due to these questions caused by loose ends which were not explained fully, because they won't ask the reason in the exam. | |
