The Importance Of Maths…

Before this module I never realised the extent to which maths is involved in every day life and how beneficial having a mathematical knowledge can really be.

In a recent module we had Dr Ellie (from the university medical school) come to talk to us about maths and statistics. She told us how important it was for professions such as doctors and nurses to have a profound understanding of fundamental maths. For example a nurse has to be able to measure correct amounts of medication in order to treat patients correctly (Education Scotland, 2008). This involves having an understanding of measurments and graphs.

Measurements are used by nurses in order to measure out the correct medicine dosage in relation to children’s weight. Nurses also have to have a knowledge of graphs and charts, in order to monitor progress and keep track of how much medication a patient has consumed (Hothersall, 2016), Thus showing how important a knowledge of fundamental maths can be in order to save lives.

Learning about graphs and data analysis is not only beneficial for employees to know but also children of a younger age. Teaching graphs from primary school will build on a child’s life skills by encouraging them to become confident individuals and function independently in society as they will have the ability to process information (Education Scotland, 2008). This may help with aspects of their future, from simple tasks like reading train times to understanding and adapting to the way in which the world is changing and be able to work out problems.

Yes, maths is essential in the workplace, but also during a persons regular day. From setting your alarm, planning how long a task will take, calculating money in a shop and even cooking dinner, many aspects of fundamental maths are involved. Such as simple estimating, problem solving and addition and subtraction. From now on instead of saying ‘im not a maths person’ I want to remind myself of the many aspects of maths I participate in pretty much every day.

Can Animals Count ?

Leave a reply

In a recent maths input I was asked the question, ‘Can animals count?’. Straight away I laughed and responded with not a chance, but after the input and doing some of my own research, I am now unsure of my answer.

The first piece of information which made me doubt myself was down to a horse called ‘Clever Hans’. In the 1900’s it was believed that Hans could count. Apparently when the horse was asked maths questions involving addition and division, it would answer by tapping out the answer using its hoof. It turned out that infact Hans couldn’t count and instead of understanding maths problems was understanding commands from his master ‘Van Osten’. Through experiments and observations it was discovered that instead of the animal quickly doing the sum in his head, he was responding to his owner’s movements to know how many times to tap his hoof (Jackson, 2005).

At this point in my research I was feeling pretty confident with my response of animals cannot count, however further into the input we looked at chimpanzees and ants understanding of maths which were the most convincing examples of all.

Over 30 years ago a professor created a study to demonstrate how Amuyu the chimp was a very intelligent animal and could respond to mathematical problems. The study showed Amuyu getting shown 9 numbers randomly placed across a screen for 60 milliseconds before they disappeared. He then was able to click the numbers in the correct order of what he had previously seen. After I had a shot and failing at this exact test I was amazed to see (in the video we were shown), the speed of which the chimp completed the task and also how when numbers were missing he was still able to remember the order they were in. This ultimately suggests that chimps can engage with mathematical skills, however I am still unsure if I’m convinced or believe this was down to Amuyu having remarkably good memory skills (BBC, 2017).

Something I didn’t know before this module was how clever ants were. When ants leave their nest to go and get food they remember the distance they have travelled by apparently counting the number of steps they have taken in order to get back to the right place. This should then mean that ants have an understanding of numbers and counting…….

Researchers Martin Muller and Rudiger Wehner decided to investigate this theory and find out if that is the case. One of the tests they done was shortened the ants legs and the other was increasing the ants legs by adding match sticks to them, in order to see if the variables would affect the ants ability to calculate the distance they have travelled back to their nests. The researchers concluded that the ants with the longer legs continued to walk past their nests and the ants with shorter legs stopped before their nests. This was put down to the ants having internal pedometers, meaning that the ants do in fact count how many steps they have taken from leaving their nest and then take the exact amount of steps back. So by having longer or shorter legs, the ants still counted their steps back to their nests but just travelled a shorter or longer distance (Carey, 2006).

From the studies I have researched I still cannot pick a side as to whether animals can count or not. I do believe animals can understand the concept of counting (proven by the ant investigation), however I’m not sure if they can count as they cannot talk meaning they don’t have words for numbers.

In the future this would be a topic in which I would be interested in researching some more in order to have an answer. I believe this would be a great topic to look at with my future class to demonstrate how maths can be fun and associated with topics they are interested in (animals).

Can animals count ? The research continues…..

Maths in Music

Leave a reply

Music has always been a subject which I love but have never been very good at, after TRYING to learn the violin (we wont talk about that today) I discovered I was never going to be a musical genius. I love nothing more than listening to a bit of Taylor Swift or watching a good musical. Sadly, that’s as far as my musical knowledge goes.

A recent maths input, which I very much enjoyed, was discovering the links between maths and music. At the beginning of the input, we were asked to think of as many links as possible, my list consisted of rhythm and beats in a bar. After being proud of coming up with 2 links you can imagine how amazed I was to discover the list is pretty much endless. Some links, which I wasn’t aware of included:

Note values
Tuning/pitch
Counting songs
Fingering on music
Time signature
Scales
Fibonacci sequence
Patterns and repetition

Patterns and Repetition

In any piece of music, pattern and repetition are usually involved in order to create a rhythm, which is a regular repeated pattern or sound (Rhythm, 2017). According to Professor Peter Schickele, the reason for this “is that regularity of pattern builds up expectations as to what is to come next”, thus making the piece more exciting and memorable. However when composing a piece of music it is essential to create the right balance of repetition as too much can make the piece boring and predictable (Schickele, 1980).

Fibonacci Sequence

The Fibonacci sequence, according to Elaine J. Home (2013) is “a series of numbers where a number is found by adding the two numbers before it”. For example, the sequence starts like 0,1,1,2,3,5,8,13,21. Lets take the number 8, this number belongs in the sequence as the two numbers found before it equals 8 (3+5+8).

In music, a chord is made up of the 1^st(the root), 3^rd and 5^th note on a scale. These are all Fibonacci numbers. Fibonacci numbers also re appear in the octave and multiple scales too (Meisner, 2012). The video below demonstrates how the Fibonacci sequence appears visually in a musical context.

The ‘music in maths’ input was one of my favourites as, even though music is something I listen to on a daily basis, I had never associated it with maths. This highlights the idea that maths is a common theme in many aspects of our lives. In the future, I would be interested in having a second go at trying to learn an instrument. After this input and with a basic fundamental mathematical knowledge, I might have more luck this time as I will be able to look out for the links!

Maths In Sport

Leave a reply

When I first heard we were going to be having lecture on maths in sport, I was extremely confused as I couldn’t think of a link between the two subjects. However, after some research yesterday, and todays input, I have been made aware of the links between these subjects and discovered how the fundamentals of mathematics are used in the majority of sports.

Before todays input, I researched the ways in which maths is used in basketball, and was amazed by the many ways in which maths can influence a player’s performance. I discovered that the force, the length of the players arms and their speed are only some factors which influence a players shot. Angles are another mathematical concept which regularly appear in basketball. For example, if shooting behind the free through line, a smaller angle is necessary as the player is closer to the hoop, and when a defender is trying to block a player a higher shot is necessary. To achieve this, elbows should be as close to the face as possible and the shot should be taken from a 45 degree angle (Mathsblaster.com, 2017).

At the beginning of todays input, we studied an old football league table in our groups. We then rearranged it to look like a modern league table, which we would see today. My group began by noting down the differences between the old and new league tables, and then started making changes to the old table. First we rearranged the teams in order of who came first, depending on the amount of games won. We also used simple algebra to work out the amount of points each team had, as we discovered that, on the old league table, if you multiplied the team’s amount of games won by two and added the number of games they drew, you would receive the final answer of how many points they had (winnings x2 + number of games drawn = total number of points).

After this activity, my group decided to create a new set of rules for netball. We considered the length of the court, the distance in which each player can move and the likelihood of teams scoring, while constructing the new set of rules.

By extending the courts length, more opportunities would be available for changeovers, as more space provided a longer distance for the ball to travel. Providing three hoops instead of one creates a higher chance for points to be made, as players have a choice to decide which hoop they are more likely to score depending on the angle in which they are positioned.

We also made a rule where the closer the player shoots from the hoop the more points their team will receive. This makes the game more exciting and competitive.

Another factor we could have considered is the surface area of the court. Having the court raised in the middle would make it difficult for players to get the ball to the other side of the pitch, as gravity would be forcing the ball back down the hill (Gravity, 2017).

In this new version of netball with new rules, players would have to consider maths constantly throughout the game. They would have to visualise the angles they should use to position themselves in order to have a higher chance of shooting. They would have to calculate the distance in which they have to pass the ball as a longer court means a greater distance for the ball to travel. Players would also have to use basic addition and subtraction skills to work out which hoop would give their team the most points and how many points are needed to win the game.

From this input, I have discovered how many fundamental mathematical concepts are used by, not only league table creators, but also by sports players to improve their performance e.g. distance, speed and time.

In the future when I have my own class, I would like to highlight to pupils how basic mathematical concepts are used in every day activites such as sport. This will provide a good example to show how maths is relevant in other subjects they may be interested in (The Scottish Government, 2008).

Profound Understanding Of Fundamental Mathematics

Leave a reply

Before starting the “discovering maths” module, I had never heard of PUFM (profound understanding of fundamental maths). To be honest I thought it sounded quite daunting, however, after doing some research and breaking it down I discovered that PUFM is not quite as intimidating as I had thought. It consists of 4 principles and according to Lipping MA (2010), “to fully promote mathematical learning, teachers must have a profound understanding of fundamental mathematics”. In other words teachers must have a deep, broad and thorough understanding of the mathematical topics in which they are and will be teaching (Ma, 2010).

If you are still as confused as i was initially, think of a bus driver. Bus drivers know the roads well and know how to make short cuts and reroute if needs be. Teachers with PUFM are like bus drivers, only relating to maths. They know the topics they are teaching very well and can take students from their understanding of maths to future learning, and in the process of this they know many ways in which the journey can do it (National Research Council, 2001).

The four principles in which PUFM is made up of are:

Interconnectedness: A teacher with PUFM is able to identify and make connections between the mathematical topics they are teaching (Ma, 2010). They are able to make links with the pupils current knowledge and their future learning, expressing how these depend on each other.
Multiple Perspective: This refers to a teacher being able to approach solutions and mathematical problems in a number of ways (Cuarezma, 2013). This can ensure flexible learning within the classroom as teacher are able to adapt their teaching and give mathematical explanation in regards to their approach (National Research Council, 2001).
Basic Ideas: This involves teachers knowing the, ‘simple but powerful basic concepts and principles of mathematics’. This allows teachers to be able to reinforce basic maths ideas within students, as some of the most basic principles in maths recur through most learning (Cuarezma, 2013).
Longitudinal Coherence: As Teachers, we have to understand that one mathematical topic builds on another, and what we teach students today is a base for future learning (Ma, 2010). A teacher must be able to revisit topics to sole date learning but also move on with their teaching in order to cover the whole curriculum while ensuring the needs of the learners are being met (Curezma, 2013).

Having PUFM as a teacher is essential as teachers must have a deep and thorough understanding of the concepts they are teaching in order to teach them to others. I will be remembering the 4 principles to PUFM when I teach maths in the future to identify how they can be applied when teaching each topic.

Maths Anxiety

Leave a reply

Looking back to seven years ago, I was in primary seven getting ready to start secondary school. Maths was something I loved and a subject I felt confident in.

Six years ago I remember sitting through a maths class in S1 looking at the teacher who was desperately trying to teach me how to do ‘The St. Andrews flag method’. I had no idea what she was talking about and remember feeling like I wanted to cry. How and when did I get so bad at maths?

From S1 to S4 maths was a struggle I remember fearing every lesson and trying to think of any excuse to avoid class whether it was ‘feeling sick’ or having ‘dentist appointments’. This of course made things worse as I began to make myself believe maths was more scary than it actually was. I began to give up listening in class or paying attention as I believed I would never understand and paying attention was in vain.

This evidently affected me as I sat crying the night before my national 5 maths exam. Frantically looking through every textbook and jotter praying for a miracle that would somehow turn me into a math genius. This of course didn’t happen. I ended up spending my whole night watching ‘Mr maths genius’ on Youtube explaning ‘sin, cos and tan’ which, to me, were just random words. To cut a long story short, I failed the exam.

Despite getting good grades in my other subjects I remember feeling disappointed in myself. Looking through every university’s entry requirements, I began to realise if I was serious about becoming a primary teacher I was going to have to try again.

Round 2….

Despite hating the walk to maths and dreading every lesson, I made sure I concentrated in class. After a year of sticking it out, I achieved an A at nat 5 maths. Out of all my grades I had achieved at Higher level, I felt most proud of this as it meant my dream of becoming a teacher could happen and maths was no longer holding me back.

A month ago I found myself sitting at a desk looking at a power point which read ‘Discovering Maths’ and thought “what have I done…?” The sheer mention of the word maths made me want be sick.

The first topic we looked at was maths anxiety. Reading through the symptoms and causes, I realised this was something I suffer from.

Maths anxiety is something I had never heard of until recently, and according to Hill, ‘is a debilitating negative emotional reaction towards mathematics’ (Hill, 2016). After researching I have discovered I am not alone in feeling anxious towards maths in fact it is believed that a quarter of the worlds population share this feeing (Brain, 2012).

When I become a teacher, maths anxiety is something I cannot bring into the classroom. I will refuse to pass my fear of maths onto any future generations. It is, therefore, my aim to become more confident in my maths abilities and defeat the monster that maths is.

Scientific Literacy

Scientific literacy and fair testing – Áine O’Neill, Gillian Daly, Iain Thomson

“Scientific literacy is the capacity to use scientific knowledge, to identify questions and to draw evidence based-conclusions.” (OECD, 2003) It allows us to expand our knowledge on science and allows us to learn about new things. It is very important to teach children about scientific literacy at a young age so they can start questioning scientific knowledge from a young age and gets them into the habit of questioning and understanding scientific literacy from a young age. Although scientific literacy is helpful with acquiring new scientific knowledge, not all scientific literature is true. A lot of scientific literature on the internet is false due to scientists lying about their results or falsifying evidence. Therefore, it is important to carefully read scientific literacy found online to make sure it is true. It is important to teach children that not everything they read on the internet is true.

A lack of scientific literacy could lead to inaccurate media reporting. An example of this is the ‘Changing diet could stop cancer’ theory.

In 1924, Otto Warburg suggested that an acidic diet could affect and be the cause of cancerous cells, after he discovered that cancer is caused by low oxygen and an acidic PH. His suggestion to patients was to change their diet to be less acidic and more alkaline by eating more of a green diet.

This suggestion caused fear within the public as it was new information released about cancer, and caused a great deal of hype within the media. However, after various investigations scientists concluded that cancer cells can not live in an overly alkaline environment, concluding that Otto’s theory was wrong. Scientists provided closure to Otto’s theory by discovering that blood is slightly alkaline, and is tightly regulated by kidneys and cannot be changed by what you consume. Due to this any extra acid or alkali that isn’t needed in the body is released from the body in urine.

Developing understanding of scientific concepts and language is a very time consuming activity. The scope of science is enormous and varied, so basic knowledge of scientific practice and language should be taught at a young age. This can be as a foundation for more skills, knowledge, and scientific inquiry required in the sciences.

Bybee (1997: cited Dunn and Peacock, 2015) suggested that scientific literacy followed a hierarchy, from knowledge of some scientific terms with no deep understanding of them, to multidimensional scientific literacy, where learners can apply concepts and theories to the world around them. There is much learning and teaching to go from the initial stage to the latter, so the introduction of science in the classroom at an early age is important.

The teaching of fair testing in schools gives children an idea of scientific practice, an introduction to scientific vocabulary, and the beginning of understanding how scientific evidence is used and interpreted. Without these skills, young people will struggle to understand the difference between scientific theories that have been verified through experimentation, and false scientific claims built on faulty, or fictional, scientific evidence (as above).

Throwback to 12 years ago….. I was a bossy 7 year old teaching an innocent 4 year old to count. After 2 hours of me nagging she eventually counted to ten and from that moment I knew that teaching was the profession for me.

In primary school I didn’t just sit in my primary class and get taught like any normal child, instead I analysed the teachers movements and noted down techniques that I would hopefully use when I became Miss Daly. Throughout primary school I used to day dream about having my own primary class and taking the children on school trips, but when I started secondary school reality hit me when I realised if I was really passionate about doing teaching I was going to have to work hard.

Third year of secondary school was when I began to doubt myself, I began to wonder if I should become a midwife, social worker or psychologist. I looked into many courses but somehow in my head I knew I was wasting my time, and teaching was what I really wanted to do. In my fifth year of school I began to go on work experience. I volunteered at nursery’s and primary schools and loved every moment. I found it very interesting to watch the way children learned and interacted with one another.

On the first day of work experience when I walked into a classroom not as a pupil but as ‘Miss Daly’ I began to see that my old day dreams in school could be turned into a reality.

So now being at uni, studying the profession that I’m truly passionate about makes me very happy, as I know that i’m on the right path to become the teacher i’ve always wanted to become.
