5 Online Resources to Help Chemistry Students ace This Year’s C-SEC Exams

Advertisements

The Caribbean Secondary Examination Council (C-SEC) Exam season has started.

It’s a season that many students along with teachers and parents approach with some trepidation, some optimism, and others with much skepticism. Especially when it has to do with Mathematics and hardcore science subjects such as Physics and Chemistry.

And one can hardly blame them. Over the last decade or certainly in the last three years, Math and Science CSEC pass rates from year to year have shown little improvement. Exam results show a consistent decline in student performance in these subject areas.

Look at these stats.

For the purpose of this post, I’ve lifted these quotes about performance in the Science subjects from the 2016 report posted by the Caribbean Examinations Council, the examining body that sets C-SEC exams for Caribbean students. On their website,www.cxc.org, the examination body reported “a mixed performance in the science subjects this year” with results recorded as follows:

Chemistry saw a three per-cent decline in performance this year when compared with 2015 with 56 per cent achieving acceptable grades this year compared with 59 percent in 2015.

There was a seven-point decline in performance on Integrated Science this year when compared with that of 2015, sixty-four per cent of entries achieved acceptable grades this year compared with 71 per cent in 2015.

Physics and Human and Social Biology improved marginally, the exam body reported.

It noted, “Performance on Physics improved marginally with 63 per cent of entries achieving Grades I-III this year compared with 61 per cent in 2015,” and  an “eight-percentage-point improvement in performance on Human and Social Biology this year, 53 per cent of entries achieved acceptable grades compared with 45 per cent in 2015.”Though a specialist area, Agriculture Science students performed best overall in this area of science,  with CXC.org reporting as follows:

“Both Agricultural Science Double Award and Agricultural Science Single Award recorded very good performance this year with slight improvement in the Single Award and slight decline in the Double Award. Ninety-two per cent of entries for Agricultural Science (Double Award) achieved acceptable grades this year compared with 94 per cent in 2015. Eighty-nine per cent of entries for Agricultural Science (Single Award) achieved acceptable grades this year compared with 87 per cent in 2015.”

Following the release of the results each year, the media has put a spotlight on the issue. The ensuing discussions have brought some insight into the reasons why the majority of Jamaican candidates are failing the Science subjects. C-SEC students have complained that the questions are challenging while some STEM educators here believe this is because students here are not making the necessary connections with real life and chemistry. One Ministry of Education STEM consultant who shared her views

One Ministry of Education STEM consultant who shared her views on a TVJ produced panel discussion, convened in 2015 to discuss the concerns over the declining pass rates in Math and Science, believes that the root of the student’s difficulty in addressing these ‘application’ level questions on exams stems from poor classroom preparation.hat same discussion, Math and Science teachers were challenged to integrate more high-level thinking and deeper learning strategies in their classrooms.

Out of that same discussion, Math and Science teachers were challenged to integrate more high-level thinking and deeper learning strategies in their classrooms.

Of course,  these are strategies that will benefit students right across the national curriculum, but Science and Math subject requires a stronger push at this time if we are to see an uptick in the C-SEC Math and Science pass rates. The Ministry of Education has also launched campaigns like the observance of National Mathematics Week and a

The Ministry of Education has also launched campaigns like the observance of National Mathematics Week and a Math Counts Expo to help primary school children engage in the subject.

To address the inherent fear for Math among citizens said to be the Ministry also embarked on television advertising to encourage Jamaicans to embrace Mathematics instead of fearing it. An emphasis on STEM in the school system and an e-Learning portal where students can freely access learning resources for Science and other subjects form part of the government’s plan to turn around the attitudes of Jamaican students and their parents to the Sciences.

One may argue that in this age of information and the world wide web, finding resources should never have been an issue for any student or teacher seeking supplemental material to expand on topics.

As a parent and teacher, I have found that there are enough free resources online to draw on, but it appears that many of us, especially our students, are not doing the needed research or maybe do not know where to start looking. Hence, the purpose of this post is to show you a few resources that will help prepare your child or student, if you’re an educator, tackle the C-SEC Chemistry curriculum. If your child is in lower school, these resources will also give them a head start in their Science studies.

The resources I’ve listed here are engaging and will help the Chemistry student learn the concepts faster as well as help them make those important real world connections. This is not a complete list, but you’ll find some interesting content to get your student or child interested. Here they are.
