junior Cert H maths Project maths more evidence of Dumbing down

There is yet again more evidence of the dumbing down of the Junior H Project maths .

(i) Question 1: (a) Give 2 reasons why -7.3 is not a Natural number .

Marking scheme : Total marks for 2 reasons 15 marks but 10 marks for one reason such as -7.3 is not a positive number!

The marks allocated per question do not relate to the suggested time for the question.

Leaving Cert 2012 Project maths Paper 2

Comparison of results obtained using different marking schemes based on a student obtaining the Low partial credit in all questions

From the table we can conclude that there has been massive marks inflation between pre 2009 and post 2009 (project maths ) in LC H maths .

The most telling result is the % attempt marks awarded .

Using the 2010 trial exam marking scheme a student who attempted every question in 2012 P2 would have received 36%

Using the 2012 marking scheme a student who attempted every question in the 2012 P2  received 49%

This is most remarkable considering that 3,000 extra (formally Ord level students) sat the exam.

More good news

If one assumes that the extra 3,000 students who sat LCH maths were probably only doing higher maths because of the extra 25 points and that they were most likely to achieve a C or D.

Then based on the number of students who achieved an A or B grade (5235 ) and the average number of students taking H LC maths (8500) in the previous years we get a remarkable result .

Pre 2012 the A/B rate was about 45%  in 2012 the A/B rate was 63%. This is a 40% inflation in the A/B  rates.

Maths Crisis what Crisis ?

Leaving cert H maths pass rate 97.7% , A,B Rate 63%

Scottish Advanced  pass rate 66%   A,B Rate 45%

Scottish Higher  pass rate 72%  A,B Rate 50%

Junior Cert H maths results

 

The junior cert results are out today and about 80% of the 27913 students talking H math (22330) achieved an A,B,or C should they all want to take H Maths at Leaving Cert because of (i)The new low failure rate at HMLC of  2.5% (97.5% *pass the exam) (ii)The attempt mark rate of 49% (a student who got no part of any question correct but attempted every question)got 49%*

(iii)The Honours rate of 84% (84%* of the students who did the exam received an honour. (*official SEC figures)

We will not have enough qualified teachers to teach them!
