Junior Cert 2013 – 2017 Maths results

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                 

Error in 2017 leaving Cert H Maths Q9 Paper 1 may have cost you points!( eventhough you got 10/20 marks for drawing an axis)

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 of students sitting exam V Number getting less than 40% and Getting A1/H1

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

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.

Project maths: Do the reforms add up for students?

Records numbers are sitting higher level maths but many struggle with basic skills

 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.

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!
