Any other AS DC struggling with GCSE science mark scheme because of pragmatics? Is it discriminatory?

DS has a statement because of his AS, specific language impairment and pragmatic difficulties. He is going into Y11 and doing relatively well in his mock GCSEs. He is really good at maths and sciences. He understands the science, but struggles to score marks because of theory of mind and pragmatics.

If you ask him explicit specific questions he would explain everything giving specialist terminology. But the questions in the exam papers are wage, indirect and convoluted. The marking scheme looks completely illogical, arbitrary to DS. From his point of view he answered correctly the question asked, but within the explicit question there were two other hidden questions and he really couldn't see them - how is he supposed to guess which other questions he is supposed to answer? There are too many other questions he could comment on, but these don't logically follow from the question asked on paper. He feels it is unfair.

For example:
Question: "Why radiator is painted black?"
DS answer: "Because black surfaces are better emitters of infrared radiation then light surfaces"
Marks: 1 out of 3. He needed to add "so higher rate of energy transfer" For DS this is self evident and contained within his answer "better emitters". He would never guess to add this. So he scores about a third of the marks!

Another example:
Question: "How would gas and nuclear power stations be used to meet the demand for electricity within 24 hours?"
DS answer: "The nuclear power station is used for baseline demand. The gas station is used to generate extra power when demand increases"
Mark: 2 out of 3. He needed to add "because of short start up time". But the question was How, not Why!

Often out of many possible valid answers the examiner only gives marks for one narrow specific answer that looks arbitrary, random to DS (even to me) in relation to the question asked. For example:

Question: "Vaccination against measles virus will not protect the child against rubella virus. Why?"
DS?s answer: "Because measles and rubella are different pathogens"
Marks: zero... not correct ???
I don't even know what the "correct" answer is but nothing in the way the question is articulated suggests that other answer. I can see what DS means by arbitrary and random mark scheme.

DS's problem is not with knowledge and understanding, but with guessing what the examiner wants. Theory of mind.

DS works very hard - 5 hours of homework and revision every day. Most of this time is dedicated to getting sense of pragmatics and mark schemes. However it doesn?t pay off. It looks to me that with exam papers like these higher marks are just unattainable for ASD DS because of pragmatic bias built in the questions.

Is DS the only one having this problem?
What can be done?

I agree this is not to do with SN. My DS has no special needs yet had exactly the same problem, one of his teachers taught him the strategy crazymum suggests of 1 sentence per mark, think of key words, etc. He did brilliantly once he learned to do this

Any examiners, exam board people here?

Non of this rubbish happened in our old style long essay questions, the examiners could give credit for understanding as well as dry facts.

This resonates

I have a dyslexic DD and she seems to manage science most of the time, but is having similar trouble with the very prescriptive answers need for Geography. It doesn't matter if you understand something, you just have to remeber the type example word for word, marks deducted for poor spelling and grammar Angry

She has a very very bright DF who's science teacher has to keep repeating "that's right, but for the purpose of GCSE, the answer is ......". Insert dumbed down exact phrase the mark scheme will allow.

I think it's due to a move to dumb down marking, make it defensible and marks close to 100% for an A* possible.

Honestly it is the same for all children trying to second guess what science examiners want in their answer.It is is nothing to do with his SN.My DB is a science teacher and 2 my DSs have done the 3 science s at GCSE and it is the bane of science teacher and science students lives!

My DC with ASD also struggle with this, their performance in exams is quite random because of this.

My DD has just taken her GCSEs this year, and the school spent a lot of time on exam technique. To be fair, many non AS DC also struggle with similar issues. Because marking schemes are so prescriptive, it is increasingly possible to give a right but not correct answer IYKWIM.

My DC's school recognizes these issues, and DD will be allowed to progress to science A levels regardless of her GCSE results, based on her teacher's assessment of her ability in science. Whilst this won't help with her CV, it will not hold her back, and so she is in a relatively good position I think.

He's not alone and despite teaching science for years I am still surprised by some of the answers on the mark scheme. The grade boundaries are ludicrously low in gsce science largely because the questions are so odd at times. I'd like to see a paper that gives students a chance to show what they know rather than questions that trip them up.
On a practical level, the best way to prepare is what you are already doing and complete lots and lots of past papers and get your son to mark them himself using the mark scheme, as this is the only way to get into the examiners mind set.
