Marking the science tests
As in 2005, external markers, employed by the external marking agencies under contract to QCA, willmark the test papers. The markers will follow the mark schemes in this booklet, which is supplied toteachers for information.
This booklet contains the mark schemes for the levels 3–5 tests A and B. Level threshold tables will beposted on the QCA website (www.qca.org.uk) on 19 June 2006.
General guidance
The structure of the mark schemes
The marking information for each question is set out in the form of tables. The ‘question’ column onthe left-hand side of each table provides a quick reference to the question number and question part.The ‘mark’ column gives the number of marks available for each question part.
The ‘requirements’ column may include three types of information:
■ a general statement describing what is required for the award of the mark;
■ examples of specific creditworthy responses showing correct science;
■ examples of creditworthy responses beyond the key stage 2 programme of study.
The ‘allowable answers’ column gives examples of ‘allowable’ creditworthy responses, showing correctscience which may not be as clearly expressed.
The ‘additional guidance’ column may include different types of information:
■ specific responses which are not creditworthy either because information from the question hasbeen rephrased, or because the responses imply incorrect scientific knowledge;
■ answers which are insufficient in themselves to gain credit, but are not incorrectscience, and would therefore not lose credit if used with a correct response.
Where two marks are available for a question which describes the relationship between twocontinuous variables, the following will apply:
■ two marks will be awarded for a creditworthy general comparison of the variables in question,eg the bigger the grains, the longer the sugar takes to dissolve;
■ one mark will be awarded for a pair of creditworthy specific comparisons, eg big grains dissolveslowly and small grains dissolve fast;
■ one mark will be awarded for a single creditworthy comparison, eg the biggest grains dissolve mostslowly.
Applying the mark schemes
The mark schemes give scientifically correct answers to each question as well as providing guidanceon, and examples of, other answers which are allowable. In cases of alternative wording or where ananswer is drawn rather than written, external markers will exercise their professional judgement.
1
The child gives two or moreresponses to a particularquestion part.
The child has not used ticksto indicate the correctresponse in a multiple-choicequestion.
The child ticks more than therequired number of boxes.
In a planning question, noanswer is given in the expectedplace but the correct answeris given in the drafting box.
The child misspells a word.
a) If a child qualifies a scientifically correct answer with a scientifically incorrectstatement, no mark will be awarded for that question part.
b) If a child qualifies a scientifically correct answer with an incorrect statementwhich is not relevant to the context of the question, the latter response isregarded as ‘neutral’ and the mark will be awarded.
Any unambiguous positive indication of the correct answer will be accepted. Tickstake precedence over any other form of response. Therefore, when ticks and anyother sort of response are given together, the boxes with ticks will be assumed to bethe child’s response. If the correct boxes are left blank, no marks will be awarded.
One mark will be deducted for each incorrect answer.Negative marks will not be awarded.
Where a child has shown understanding of the question, the mark(s) will be given.
a) If it is clear that the child has made a simple error, eg ‘tow’ for ‘two’ or ‘son’ for‘sun’, then the incorrect spelling will be accepted and the mark awarded.
b) If a child misspells a word copied from the text of the question or from aselection given, and the new word does not have any inappropriate meaning,the incorrect spelling will be accepted and the mark awarded.
c) If specific scientific vocabulary is required in the answer, a creditworthymisspelling must be a phonetic equivalent of the required word, with the majorsyllables of the correct word represented in the answer.
What if...? Marking procedure
Recording marks awarded
In the margin, alongside each question part, there is a mark box for each questionpart. Depending on the type of response made to each part of each question by thechild, the external marker will put one of the following into each box:
‘1’ for an acceptable/allowable response; ‘0’ for an incorrect response;‘-’ if no response is made.
The number of marks gained on each double page will be written in the box atthe bottom of the right-hand page. The total number of marks gained on eachpaper will be recorded on the front of the test paper, and on the marksheet.
Each paper has the following number of marks available:
■ Test A has 40;
■ Test B has 40.
The 2006 key stage 2 science tests and mark schemes were developed by theNational Foundation for Educational Research (NFER) and the Centre forResearch into Primary Science and Technology (CRIPSAT) on behalf of QCA.
