nus bell curve
Well, it’s easy to remember at least! I am a lover of learning. The university admitted to using the bell curve for grading purposes after the story was released. I am from the science faculty, and have heard “90%-true rumors” from seniors on which professors to try to avoid, because getting an A- or above from those professors is close to impossible. Additionally, much goes on post-exams, before the grades are finalized and released to students. I graduated from NUS in 2009. The NUS administration also does not operate in a “we know what’s best for you” way; this blog project is in fact a portal through which I can interact directly with students and get direct feedback on what’s best for you! In terms of the impact the marker has on a bell curve grading, it is ok as long as the same marker marks the same question across all papers, or a highly standardised key is used. The perpetuation of transparent systems requires responsibility from both sides – we, as people who run, maintain, and reform the system need to communicate to the students the rationale for certain traits that exist in the system and justify them, but the students, if sincere about introducing meaningful reform, need to be responsible in their use of language as well. I think we singaporeans also need to be less critical of everything and be able to adapt to all sort of systems. In normal cases, no one will satisfy with a low grade. which is approximately 3.34, or roughly B grade. Given that most students probably would not go into research after their graduation, i find that requirement irrelevant. The weights of NUS students probably follow a normal distribution too. We have been engineering our environment for thousands of years, nowhere near to simply adapting to it. NUS need transparency for the exam and grading system. Today is the last day of recess week. The benefit of having a “senior” who has taken the same course under the same lecturer, and passing his material to you, is tremendous, as I can personally attest. Without the bell curve, an absolute grading system wouldn’t completely get rid of kiasuism either. I don’t. Second, we are not looking for a perfect fit, i.e., we usually ignore small deviations. Which module do you think people will take? Can there be special consideration for those with learning difficulties, like a special one to one consultation with the lecturers and more assessment time for quizzes and exams? As such, NUS adopts a ‘recommended grade distribution’ in the following manner. Once you make it through your 1L year, the curve will change for your 2L and 3L year. 3. Should we simply care about crossing the line between one grade and the next? For LSM1401, Chemical Engineering, Pharmacy and Chemistry students all have similar A level qualifications, and it is fair to put them all in one group for teaching and for grading. Effective with the September 2008 graduating class, the GPA cutoffs for each category are determined by the combined GPA distribution from the preceding academic year, all graduation moments included. A university that panders to the likes of students is not a university. NYU, for instance, is a private college and takes in a small group of very good students. Our problem is always one of scale. I am heartened to see students posting lengthy and some well-considered commentaries. You need to be really careful with reading the questions and its options, and not to over think. 4. You could say in that case that no one is qualified to mark exam papers. Spam protection has stopped this request. I like your suggestion that our Deans and Heads attend classes to get a sense on the teaching. Finals was a completely different monster. I just looking forward to your new works!I have really enjoyed reading your blog posts.I’m actually enjoying the theme/design of your blog.Hope you have another good post! In a blog post written in 2012 by NUS’ provost, it was explained that the need to modify grades is partly due to the varied backgrounds of the examiners. I am from the business school and would like to understand why the classification of first class honours is dependent on not just CAP but also a thesis component. So if everyone is able to retain the highest understanding in his field, what is wrong for everyone to obtain first honour? In my humble opinion, this could allow for a more straightforward in the analysis of consistency throughout the duration of the course. An A may be an A, but 80% for an A or 100% for an A make a different to students’ perspective. However, NUS employs a recommended grade distribution in addition to the bell curve, the actual spread of the grades will be different from a standard normal distribution. And in the event that everyone is first honour graduate and is able to show their outstanding capability at work, that will greatly improve the reputation of the university. For instance, if a lot of students report that they found the exam easy but for some odd reason their scores prior to grade assignment were low, that could signal a serious conceptual error that must be addressed. Generally speaking, someone who has already passed through the Bachelor’s system should be ok for marking. NUS grades their students on a bell curve system, much like how A levels are graded. To my understanding, effectiveness of learning is how much you can apply that understanding you have learned to the subject or work that needed this understanding. But then without that system, employers would also have an even greater headache sorting through potential applicants for positions. For me the meaningful challenge is to make NUS a better place for current and future students. #3: Thanks, Kim, for the nice story about the Economics professor. Even with successful implementation of the best system thought of, who knows really how good is it? This is a very effective way to learn the real lesson. Be it political or school grading. While we are on the topic of grades, I have an honest question which I hope the provost can shed some light on. AY17/18 Sem 1 CS2103T - CS2101 - CG2271 - EE2020 - EG2301 - GEQ1000 CS2103T Software Engineering Difficulty: Hard Grade Obtained: B+ Lecturers: Prof Damith This is a 4MC core module for CEG students so there's no escaping this. One of my second year core modules had an average grade of C, with most of the class doing badly and almost nobody getting A. Even for large classes, if the professors provide good reasons and convince us that students have learnt, we would be happy to accede to their request. So biasness in exam should not be the reason why bell curve is used. Further checks are conducted at the University level by the Board of Undergraduate Studies and Board of Graduate Studies to ensure that there is consistency of assessment across Faculties/Schools. I forgot to add, most likely your final exam papers are graded by the grad students (esp Science, Com and Engineering course with class >100), and not by professors themselves. In probability theory, the normal distribution is a continuous probability distribution that has a bell-shaped probability density function, known as the Gaussian function, or informally, the bell curve. Most if not all major universities have variants of degree classes or GPA scores. 2. I have come out with 4 points that show why bell curve is unnecessary. For smaller classes, Professors are given discretion on an appropriate grade distribution because small sets of data may not be normally distributed. Likewise, if I set exams targeted at the average competency of a group of students, and if the class is large enough, the exam scores are likely to follow a normal distribution curve. I humbly suggest that NUS should come up with a short one-page letter, that would help NUS students be more competitive when going for further studies. We need to complement exams with other instruments. #6: Grading aside, one of the best way to learn is to teach. Do not worry too much, more often than not, we err on helping students along. I humbly propose that NUS should have a letter explaining its bell curve, to help NUS students applying for graduate schools in the US/UK. #18: It is true that NUS has expanded (in student enrolment) quite rapidly over the last 10 years. And for the NUS examination system to be fair, allowing students to see their graded papers is indeed necessary, even if they are not returned to them but kept by NUS after the reviewing.

The bell curve is used as a guide in a class of "reasonable size", referring to 20 or more students, in the following manner: 20 per cent to 25 per cent to get A+, A or A-; 35 per cent to 40 per cent to get B+ or B; 35 per cent to 40 per cent to get B-, C+ or C; and 0 per cent to 5 per cent to … First, the grade profiles for individual modules are examined and compared at the Department level, and then across Departments at the Faculty level. In the business school, where there is no direct honours, most students who are weaker would graduate in three years. Meritocracy must necessarily lead to kiasuism. For example, some modules belonging to special programs in the various Faculties/Schools have their own distributions. I agree with Douglas and MJ on their views regarding the classification of first class honours. on the same note, how about exchange students? I know at least one module where a lot of lecturers from the same department shared the marking of all the final examination papers because it was a huge class. The bell curve is also known as the normal distribution, and this is what it looks like: source: mathisfun . I believe this is setting students back in the working world, where employers may not understand the technicalities between the degree classifications in the various university. If the current NUS administration did not value the feedback of students at all, the 2nd highest ranked member of the administration wouldn’t be wasting time on this site. #9: Thanks, Jack, for arguing very convincingly why moderation is required to smoothen the effects of exams, despite the fact that it is itself an imperfect tool for testing learning effectiveness. P2:12 Openly engaging the institution you are ostensibly trying to change in a hostile manner is unlikely to produce the desired result of change. if students. The professor (it was said) rigorously demanded these grades because the cohort did not know the material and he wanted them to know it. This would have the effect of reducing competition between students, reducing kiasu-ism. I could get a Secondary 3 student to grade it; if she follows the given key closely enough, I find no issue in letting her mark me. Dear Jensen – thanks for sharing your thoughts. Hell, I don’t. Students have complained that it heaps unnecessary pressure upon them to outperform their peers. Posters, oral presentations, interviews are all continuous assessments used more and more by our professors. So yes, even though it would be theoretically “fairer” to students if exam were released, the presence of the above type of students totally negate and reverse the “fairness” of releasing the exam. You had raised relevant points in your previous comment, including the return of exam papers which does have merit to it, but as I have said, it is another one of my battles as Provost. 2. And while my earlier points may not have been too “diplomatic”, the points raised are nevertheless relevant, but were unfortunately glossed over. Is it justifiable for us to change for the environment or do you think that it is better for the environment to change for its students? Thanks for alerting us on the computation and we’ve adjusted it! 1. This trains you to be more judicious about priority setting and time management between Hall life, CCAs, activities beyond university and studies. NUS need transparency for the exam and grading system. (b) Have obtained a grade of A- or better in at least 40% of the subjects taken at NUS. #P1:9 What was the outcome of the discussion on the evaluation? There are no two ways about it but to ensure that our CE students are competent in both. For such scenario , why is it not possible that the school gives everyone the same grade since everyone is good at the paper? But if the benefits of something new outweigh the costs of changing from the old, we should not dismiss it just like that. My students told me of professors who contact the students who are potentially going to fail the module, and some even counsel them individually and suggest that they ‘withdraw’ in order to protect the students’ CAP. As of this moment it makes no difference to CAP, but I’m sure you’ll agree with me that a student with 9 A+ and 1 B+ deserves a better appraisal based on results alone than another with 9 A and 1 A-; at the moment there is no academic incentive for students for either NTU or NUS to go for A+. McGill’s practice is good and warrants a close study. Based on my understanding from the past 18 years of education, learning is the understanding of a subject, which will be used to complement future work or more understanding of relevant subject. #10: Alex thought that it is unfair to subject exchange students to our high standards. This paper tests applications of concepts extensively/this paper is mainly an exercise in regurgitation. Alas, one must always temper one’s expectation, after all this is NUS. It was too easy and the bell curve was very bad. #5: I sense that you may have taken the GEM Living with Math, and found that you did not learn anything valuable. While it is easier to have a program like the USP for 200 students, our challenge is to scale up such experiences 30 fold. Lastly, I do not understand the rationale behind having a bellcurve for level 4000 modules in Business School. What this means is that only a fixed number can score As for a subject in bell curve,while for absolute scoring,as long as you hit the intended score,you get the grade. The Bell Curve God usually sleeps in NUS or NTU residences, and is usually woken during recess week, where desperate university students seek answers. For instance, a professor may set what seemed to be a difficult paper, but he may have posed similar questions during tutorials or discussions.
