Analysis of Official Marking scheme LCH Project maths Paper 1 2012 .
Standards in freefall towards the bottom .The reasons for such a generous marking scheme are as follows .
(i)The extra 3,000 students who came up from Ordinary level who were there just for the 25 extra points (98% of those got the 25 extra points) and were not able for the papers.(ii)The exam was an experiment in full blown project maths and the experiment failed!
Note in 2013 there was little or no project maths on the leaving cert papers, is the SEC fighting back?

Question 1; Coordinate geometry of the Line
(a)Incomplete statement of method 9 marks out of 15 (60% )
(b)Any reasonable step 4 marks out of 10 ( 40% )
52% of the marks for any reasonable step!
Question 2 Coordinate Geometry of the Circle
(a,b,c,d) Any reasonable first step 15 out of 25 marks (60%)
Question 3 Coordinate Geometry of Circle .
Any reasonable first step such as g = f 15 marks out of 25 (60%).
Writing centre as (r,r) 20 out of 25 marks (80%)
Question 5 Probability/Statistics :
(a) Some relevant diagram 7 marks out of 20 (35%)
Question 6 Geometry :
(a) Any correct step 4 marks out of 10 (40%)
Question 7 Statistics
(a(i)(ii)(iii) Incomplete or Partial Statement 11 marks out of 20 (55%)
(d) (i)(ii)(iii) Uses a relevant number 11 marks out of 25 (44%)
(e) One relevant step 7 marks out of 20 (35%)
Question 8 Robotic Arm
(a)(i)(ii)(iii) 55 marks out of 75 (73%) for Using Pythagoras and the Cosine Rule twice.
In the pre project maths exam this would have been worth 25 marks.
Note also the “low partial credit for part (a) was 27 marks out of 55 (49%)
Getting the average mark for these questions for just turning up 47% That is 47 % of the marks for these questions were given for attempts and getting no correct answers.!
This came from teachers at the meeting on Mon,who taught the relevant levels this year.This is a litany of errors,Typos ,topics no longer on the course being asked.In one case Q8 LH P2 the question as asked had a triangle that cannot be constructed!

Question 1 Statistics : Much more straightforward than 2012 but parts a and b are basically the same thing.
Question2 robability this was all over the place not difficult dame as q1 2012 P2 but this time you were given the numbers.Most students did not know what a Bernoulli trial was.
Question 3:The line .typical old course question most should be happy .
Suggested solutions (a) -1.5,(b)2x-3y-14=0,(c)(-2,-6)
Question4:The Circle: Would have suited most people part (c) would have tested weaker students
Suggested solutions(a) x^2+y^2=100,(b) (x-4)^2+(y-3)^2 =25 (c) (8,0)
Question 5: Area/Volume Odd question lots of space most should be happy ,part c may challenge some students.
Suggested solutions(a) Lenght of rectangle 62.83mm,(b)4500Pi(c)900Pi.
Question 6A: Geometry /Construction pretty basic .
Question 6B Ignored by most students but there is a lovely way of doing this by breaking the diagram into the three triangles APC,BQA, and BCR.
Question7: Statistics Another dreadful question spread over 4 pages by the time you got to the end of this you had lost the will to live!Students had to flick back and forth to check the data.
Suggested solutions (c)Median 50,inter quartile range 5,(d) mean 78333,(dii)68-89(e)4,556,000(f)27792
Question 8:Trigonometry : Nice question but spread over 4 pages! They asked the entire trig syllabus.Most students should have got some marks.
Suggested solutions: (a) 60 degrees (ii)389.7 (iii)82.6% (iv) 30km(v)Equilateral triangle.(b)188Km (iii)90degrees(iv)45 minutes(c)(i)25.98km(ii)17.32Km
Overall verdict :Most students happy but something will have to be done about big questions spreading over 4 pages.
The 24 Pilot schools asked to answer question on Topics not on the course !
Paper 1 Friday 7th June LOrd Project maths Phase 3.
Pilot School students were surprised to discover that they were been asked to answer questions on Differential Calculus which are no longer on their course.In fact they are not part ofOrd Level strand 5 functions and Calculus which was examined for the first time in 2012.
In Paper 1 question 5 (a) Students were asked to differentiate a product but the product rule is no longer on the Ord Level Syllubus. In question 5(c) on the same paper they were asked to differentiate a quotient but the quotient rule is no longer on the Ord level course. Mistakes like this are unforgivable you would think that those setting the exam would know what was on the course.
This was a 25 mark question 2/3 of which was not on the course.
Meanwhile on the Higher (Question 5 Paper 1) paper students were asked to find the area between a sine graph and the x axis using Integration but finding areas under sine curves by Integration are not on the course !
This rendered pats c and d of this question invalid .
Verdict easier than the samples or 2012/2o11 papers
Question 1 Probability .Nice question But lots of rote learning.
Question:2 Normal distribution very predictable part b may have caused problems.
Suggested solutions (a)0.9452,(ii)0.08904
Question : 3 The Line very basic just about Ord level standard.
Suggested solutions (a)l,l,h,m,k and l (b)30 degrees
Question ;;4 The circle Not a bad question similar to old course
Suggested solutions b(i)-7/5,-4/5 b() 4x+3y+8 = 0
Question:5 Trigonometry ;Again very basic question ,similiar had been asked before on Ord level.
suggested solutions (b)49,131,(c)7
Question6 :Geometry More rote learning ,Construction of the Orthocentre for a triangle with an obtuse angle was expected.
Question 6B :Geometry .(a)Very basic junior Ord level.
Question7:Probability/Statistics; not a bad question far too much information.
suggested solutions 0.231,0.238,not independent ,(e)0.7 is outside confidence interval. No new margin of error is 0.2236,(f) 0.88.
Question 8:The question with the impossible triangle.
suggested solutions (a)(i) 37.62KM or 47.02km (ii)193.93km or 168.35
Question 9 ;Trigonometry /Geometry Looked much worse than it actually was . It ran out of ideas before the end.
(a) k =4/2 ,.(b)P =2piR1.(ii)8pi c(iii)9pi(d) Show the figure TCRS has 4 right angles.
Teachers have discovered that the triangle given in question 8 paper 2 has too much information in it .
The dimensions of triangle HRP are given as follows /HR/=80km,/RP/=110KM the /<HRP = 124′/ and /<RHP =36′/
It follows that the 3rd angle is 20′ .
(a)i asks to find the perpendicular height of the triangle which is 80 sin 36 = 47.02 or 110sin 20 = 37.62 not exactly equal .
(a)iiThey asked you to find /HP/. Using the area of a triangle method you get /HP)=193.92km which is strange as it fails the triangular inequality rule /a/</b/+/c/.
If you use the cosine rule you get /HP/=168.35km .
But the story does not end here.On the Irish version of the paper the angle of 36′ was omitted in the diagram but the Irish speaking schools were contacted by the SEC to sort out this error.But if the SEC told the Irish speaking schools to insert the 36′ it means they were not aware of the error that the triangle with these measurements was impossible.
The following is an extract from a post on Twitter by Minister Sherlock concerning the 2012 marking scheme .
“Marking of the exams:
Standards do not radically vary year on year for large cohorts of students. When new
knowledge and skill sets are being tested the standard required is difficult to tie down in the first year.
Editors Comments :2012 was in fact the 3rd year project maths was examined.
This is particularly the case with Project Maths where candidates are developing new skills
and more are sitting the exam at higher level. These candidates cannot be treated unfairly
compared to previous candidates.
The exam papers and marking schemes for Project Maths are new. For this reason, some latitude is required in the development and implementation of the marking scheme. This is fully in line with international practice in large scale public exams like the Leaving Certificate.Last year, the number of candidates who got an A1 was 345, compared to 486 in 2011.
Editors comments The A1 % rate in 2012 was 3.2% : The A1 Rate in 2011 was 5.9%:The A1 % rate in 2010 was 7.5% and in 2009 the A1% rate was 6.9%! Project maths has reduced the numbers getting A1 by 50% .
This does not suggest that the exam has been “dumbed down”. In contrast, 256
candidates were awarded an EFNG grade in 2012 compared to 246 in 2011. Whilst any
increase in EFGN grades is not desirable, a difference of 10 candidates is in no way
Editors comments :The failure rate in 2012 was 2.3% (lowest ever)Pre Project maths the failure rate was about 4%! Project maths has reduced the failure rate by 40% !
The State Examinations Commission (SEC) is satisfied that the marking schemes used in
the marking of the 2012 Project Maths examinations were fully appropriate and fit for
purpose. The development and finalisation of these schemes followed the normal
practices and procedures which apply across all exams delivered by the SEC in the early
years of a new syllabus”.
There is only one different question on this paper in comparison to the regular paper.
Question 9: Functions/Calculus:Parts a,b very easy ,c,d,e,f may have caused some difficulty but if teachers had practiced this type of question there should not have any problems.
Verdict : about the same level of difficulty as the regular paper.
Question1:Complex Numbers . Nice question provided students were familiar with modulus .Nothing new here.
Question 2: Algebra/Area .Trapezoid rule a bit of a surprise but the table will get most marks even if student uses the table function on the calculator.
Question 3: Number :Parts a,b, just use your calculator (foundation level ML) ,(c) will have troubled some students.
Question 4: Compound Interest /Money; Just use your Calculator (ML says a half decent 1st year could have done this question.
Question 5: Patterns/sequences:Same question as the flowers on the sample .Weaker students will have struggled with some parts of this question.
Question 6: Patterns /Number; Identical to question 5; Probably more difficult than Q5 as it had more parts.
Question 7:Calculus (old course);Part c will have troubled some students ,although not difficult it is based on the old Q8 which mant students tend to avoid.
Question 8;Calculus Old Course : Part b (max and min plus graph )Students would normally be given a domain (none given here) this may have upset some students.Part c was expected identical tom old course.
Verdict : Nice paper ,easier than the mocks , the worry would be Q5,Q6, depending how they are marked.
The big difference is the style of questions very similar to the old course ,very much to the point , very little English .Very little in context questions.This looks like that project maths in it’s original format is dead !
There were 3 different questions on this paper in comparison to the regular paper .
Question 5 : Functions/Calculus.Given 4 graphs and asked to identify the graphs of the first and 2nd derivatives.This is a recycled question from the old course .Based on the fact if you differentiate a quadratic you get a line if you differentiate a line you get a constant.Very,Very,Very easy should have taken 2-3 minutes.
Question 6:Functions/Calculus/Area :The trapezoid rule not expected on H paper but again very basic.
Question 8: Functions/Calculus;Identical to Sample infact practically the same question !On the sample it was a snowball here it is a raindrop. 50 marks for very little .The Calculus on the regular paper was more difficult .
Verdict : The Project maths paper for the Pilot schools was easier than the paper used by the regolar schools.
