We have analysed the Junior Cert Maths results 2013-2017 .The table below show the percentages getting A,ABC,D and fail . We have also plotted a scatter plot and calculated the correlation coefficient of numbers sitting the exam versus % A grade .You would think that as the numbers sitting the exam increases the % A rate would decrease but no! The % A rate actually increases. There are a number of ways of explaining this.(I)Standards have fallen ! (ii)The % rate getting A is being manipulated !

Year | A | A,B,C | D | E,F,NG | Number |

2017 | 14.1 | 74.2 | 21.5 | 4.5 | 34822 |

2016 | 11.7 | 76.3 | 20.2 | 3.5 | 32830 |

2015 | 11.3 | 74.7 | 21.1 | 4.2 | 32535 |

2014 | 10.7 | 73.00 | 22.5 | 4.5 | 32041 |

2013 | 12.0 | 78.4 | 18.4 | 3.3 | 30500 |

In question 9 Leaving Cert Higher Maths Paper 2017. Students were asked to insert scaled axes on a given diagram .The marking scheme gives 10 marks (out of 20) for drawing a vertical or horizontal axis (unscaled) or 18 marks for fully scaled vertical or horizontal axis. So why are the marks so generous?. Reason **the question cannot be done !** The information in the question is conflicting and incorrect.

We are given f(t) = a+bCosct and told that f(2)=5.5 and f(14.56) = 5.5, but using information in the question we get f(0) =5.5 ,f(2) = f(14.56) = 4.6 .It is therefore impossible to label and scale the axes .**Any student who attempted the question should receive full marks (20).**

Leaving Cert H Maths Results Number sitting exam V Number getting less than 40%

Year | total sitting exam | % getting < 40% | Number getting <40% E,F,NG,H7/H8 | % getting A1/H1 |

2017 | 16395 | 8.3 | 1361 | 5.8 |

2016 | 15198 | 4.5 | 683 | 5.6 |

2015 | 14961 | 5.0 | 734 | 5.2 |

2014 | 14322 | 4.5 | 644 | 3.9 |

2013 | 13014 | 3.3 | 429 | 5.6 |

2012 | 11131 | 2.3 | 256 | 3.4 |

2011 | 8237 | 3.1 | 255 | 5.7 |

2010 | 8390 | 3.6 | 302 | 7.5 |

Scatter Plot of Numbers sitting the exam V % getting marks < 40%

The correlation coefficient is +0.7062 indicating a strong correlation of % failure rates (<40%) and numbers doing the exam .The more people that sit the exam the higher the % failure rate .2017 had the highest failure rate 8.3% ever! Over 3 times the failure rate of 2012 and more than twice the average % failure rate from 2010-2016

Scatter Plot of numbers doing the exam v % getting A1/H1

Correlation coefficient (r): -0.29426139992469. (2010-2017)

Indicating a very weak negative correlation between students sitting the exam and the % getting A1/H1

I we just include the data from 2012 -2017

The Correlation coefficient (r): is 0.69763743659003 this indicates a strong correlation between numbers doing the exam and the % getting A1/H1.This is interesting as you would expect as the numbers sitting the exam increase the % of A1/H1 would decrease.

Five years ago, Project Maths was rolled out to secondary schools around the country.

Around the same time, students were offered the incentive of 25 bonus CAO points if they sat the higher-level paper.

Thousands responded to the incentive; this year, a record 36 per cent of Leaving Cert candidates took the more challenging paper, up from 20 per cent in 2011.

But have the changes to maths education been a success, and is it time we looked at it afresh?

**Algebra is disappearing from the Junior Cert Higher maths exam and Syllabus.**

On first look at the Junior Cert H Algebra syllabus there appears to be very little change.

But on deeper inspection the significant absence of equations of the form( a/x ) +b/(x +c) = d

And ( a/x ) +b/(x +c) = d/(x)(x+c)

Is very worrying

Students are arriving into higher level leaving cert maths totally lacking the skills required to survive leaving H maths

**How the marks (and content) for Algebra has decreased;**

Years | Marks (out of 300) allocated to algebra | % Total Marks(600) |

1970’s | 150/300 | 25% |

1980’s | 150/300 | 25% |

1990’s | 140/300 | 23.3% |

2000’s(before Project maths) | 140/300 | 23.3% |

Project Maths | 75/300 | 12.5% |

Another very worrying trend is there is **no Algebra** in the Common Introductory Course for Junior Cycle Mathematics! In many cases students study no algebra until 2nd year!
