/ GCSE Biology Marking
This has included some past papers. Many questions are of the form "explain/give a reason for X".
Looking at the mark scheme, it appears that no marks are deducted for wrong answers.
For a one mark answer, you could put down two possible answers e.g.
- deep roots
- shallow roots
If one of these is correct, then you get the mark.
Is this correct?
I don't know if this is still the case, but there used to be a general principle (so not in the mark scheme for individual questions) that you would loose any marks awarded for statements you then contradicted.
My teachers would write eg "+2" next to the correct answer and "-2 SIF" next to the wrong one. SIF standing for "shot in foot".
When they say no marks are deducted for wrong answers they mean wrong answers that don't contradict the right answer you also gave.
That was 10 years ago mind...
I wouldn't be surprised though if you didn't loose marks for putting two contradicting staments
e.g. if a person lists several correct answers then that's fine they will get 1 mark.
If they put two answers for a 1 mark answer then if one is incorrect it will negate the correct answer and they'll get nothing.
Occasionaly they say in the mark scheme IGNORE xxxx which wouldn't negate a marking point.
Mark schemes are quite pedantic when it comes to what will and what won't be accepted. You would almost definitely not get any marks for putting all the possible answers to a question. Marks are never deducted, they just don't get given if the answer is wrong or not answered acording to the mark scheme.
make sure he understand the importance of looking at the question and paying particular attention to the number of marks available to that question. if it's just 1 mark - just a word that answers the question will generally suffice.
It is very rare to get a science exam question with more than 3 or 4 marks available for a question. The reason for this is simple - it's easier to mark.
The general advice is to spend no more than 1 min per mark and USE SCIENTIFIC WORDS where necessary.
Not any more. we have 6 mark questions now. 3 per paper so about 30% of paper. The main aim i would say is to aim to get SOME marks on each of these. There are 3 bands to the answers L1 L2 L3. to get
L1 generally incomplete science, poor use of techinal terms.
L2: technical terms used correctly and partly complete explanation OR complete explanation but naff language
L3: the full shabang.
I would aim for L2: the advice i'm giving my students is to list at the side all technical terms to do with the answer/topic and then write an aswer incorporating them - as long as they know a bit of the science it might open up L2 which is enough imho.
I have noticed a few questions that ask a question based on some given info. The answer required is Yes or No backed up with reasons.
Full marks can be achieved with a well argued yes or no.
I find these really odd, because often there is not enough data to answer either yes or no and no marks appear to be available for stating that a yes or no answer is not possible because of X.
The exams are certainly wordy (biology, chemistry and physics) with few calculations and no requirement to know even the simplest of formulae -which are often give, so the student just has to plug the given numbers in.
There must be quite a big gap now between GCSE and A level in these subjects.
