# Stick or Twist

Gambling – the activity or practice of playing at a game of chance for money (Dictionary.com). But are we really playing by chance? Let’s find out.

First let’s discover what chance is;

Chance is the possibility of something happening (oxford dictionary). It can also be described more mathematically as probability.Say you have a coin. It has two sides; heads and tales. If you flip the coin your chance of getting one of the sides is 1/2.Take a dice, it has six sides. Therefore, by rolling it you have a 1/6 chance of it landing on any of the sides.

probability of an event happening = number of ways it can happen / total number of outcomes (mathsisfun.com)

The first ‘chance’ game we are going to look at is the “Monty hall problem”. This is a situation where you are faced with three doors; two of which conceal goats and behind the other is the star prize, a car. The game show host will ask you to choose a door. After doing so he or she will then reveal one of the doors that you have not picked and reveal a goat. You will then get the choice to stick or switch from the door you have originally chosen. This leaves you with a 50/50 chance, right? Wrong.

So how does this work? By switching doors, you actually change to probability of picking the car. There is a 1/3 chance that the prize is behind the first door that you picked. Therefore, there is a 2/3 chance that the prize is behind one of the remaining doors. Since we know that the prize cannot be behind the door that the game show host has revealed, the probability affectively concentrates to the remaining door – leaving its probability as 2/3 (gizmodo.com). So, you are twice as likely to win the prize by switching doors.

“New research shows that almost half of people in Britain gamble” (Gambling Commission). Is that not shocking? And we are all losing money. “Each game you play at a casino has a statistical probability against you winning. Every single time. This house advantage varies for each game, and helps ensure that over time the casino won’t lose money against gamblers. For people who are really good at Blackjack, the advantage for the casino might only be 0.5%, but certain types of slot machines might have a 35% edge over a player, and other games fall somewhere in between” (Investopedia.com). Of course, people can win, and they do, but the amount of people who do not drastically out-weighs the amount that do. As a nation, we are throwing out money into a pot where the probability is stacked against us.

We are not playing by chance. We are participating in games and gambling where it is designed and planned that we will lose. Just like the Monty hall problem we have to consider the probability of our actions whilst we are playing games to win. The games are designed to make us believe that our chance of winning is no what we think it is. The only way around this is maths. By calculating our probability of winning we can participate in games that give us a better chance of leaving it better off than we started.

# Doctor Who?

Time Travel – a Doctor Who-esque phenomenon that has been a fantasy to many for thousands of years. But it turns out that we have been doing it all along. How? You might ask. The answer is simply light, the five-letter word that we all take for granted. Light has been enabling us to see way back in time for ages and ages, literally.

Take the big bang for example. We have learned that we can see right back until a few million years before the Big Bang and it occurred 13.8 BILLION years ago. So how is this possible?

Let us put the universe into perspective: if you were to drive on one straight road around the Earth at its largest circumference, 24,900 miles, at an average on 60 mph it would take 415 hours – 17 and a half days (Quora.com). We are just one planet in our solar system made up of 8 planets in which we are the fifth smallest – Jupiter being the largest at 1120% of our size (universe today.com). Feel small yet? Well our solar system orbits around just one start in our Galaxy – the Milky Way. There are approximately 100,000,000,000 stars in our galaxy. That means we are 1 in 100,000,000,000… feel small now? But that is just a galaxy, galaxies make up our universe – in fact, 100,000,000,000 galaxies make up our universe. This colossal number of stars has intrigues people to put this into perspective, people like Carl Sagan who came to the conclusion that there are in fact more stars in the universe than grains of sand on all the beaches and deserts on Earth COMBINED (outerplaces.com)

So now we know roughly just how big our universe is we can now begin to understand why we can see back in time. Because our universe is so exponentially massive, the time it takes for light to be emitted from a source and then to reach a telescope on Earth is astronomical. This distance is measure in light years – the equivalent distance that light travels in one year. So, if a star is millions of miles away that is emitting light we will not see that light until the amount of light years it takes for that light to reach us, therefore we are seeing the light that has been emitted in the past. Between the time it takes for the light to be given off and then to meet our telescope, that star could cease to exist and we would not know until the light no longer reached us, light years later. Hence, we are seeing back in time.

If you wanted to see back in time you don’t need a Tardis, your answer is all in light.

# A Different Way to Learn

I love maths. I find the subject to be so challenging yet so satisfying that I was able to enjoy my experiences of maths throughout my education. My love of maths began in my Primary 5 class when my teacher provided myself and my classmates an opportunity to learn maths in a different way, through play.

Maths through play is an unconventional method of teaching maths skills according to the old traditions of teaching. Maths has always been perceived and a ‘textbooks open, sum after sum’ subject. This old-fashioned way of teaching leaves children bred and disengaged from one of the most valuable curricular areas. By teaching maths trough play we are opening up the possibilities for all children to be able to work problems out in a way that suits them.

According to the Curricular Guidance for pre-school Education “Play is an effective vehicle for fostering Mathematical concepts and developing positive attitudes to mathematics…” This shows that children will be able to successfully deal with more complex problems through play rather than by traditional methods as they are given the opportunity to discover their own way to solve problems. By teaching maths through play, we are allowing children to enjoy the maths that they are learning. Maths will be less daunting as they are learning in a fun and engaging way.

So why can children learn better through play? “Young children engage in significant mathematical thinking and reasoning in their play – especially if they have sufficient knowledge about the materials they are using – if the task is understandable and motivating if the context is familiar and comfortable” (Scholastic) If a child is more engaged in their learning they are more likely to gain a higher level of understanding. If a child is disinterested in their learning they will not be able to take anything from it, therefore the teacher’s precious time will be wasted.

Rather than delivering content rich lessons we should be delivering valuable, engaging and worthwhile lessons. In order to engage more children, we should be delivering lessons that provide them with opportunities to learn in the best way for them. So, learning maths through play can spark new ideas and enthusiasm for the subject and therefore leave children feeling more engaged and confident.

# The Process of Reflection

Semester 1 opened my eyes to many different issues over the course of the 12 weeks. The values module in particular made me think specifically about my own values and beliefs that will shape the way I conduct myself as of now. Before this module I failed to realise the importance of knowing and understanding my own values. I am unable to pinpoint an exact moment where I realised how important my personal values are to my professional development as it was definitely a progressive process.

The SPR states that student teachers should “adopt an enquiring approach to their professional practice and engage in professional enquiry and professional dialogue” and the values module certainly encourages this. After the lectures, very often myself and some peers would gather for lunch or in a café and we would find ourselves having good, professional discussions about prior lectures. Throughout the semester I found myself discussing the topics of feminism, race and sexuality the most often as I found these topics very interesting.

Another standard in the SPR states that one should be able to “reflect and engage in self-evaluation using the relevant professional standard”. The values module helps to ensure that each student teacher understands how to act professional and take into consideration every factor of a child’s life not just the immediately apparent ones. This enables us to teach a child the most appropriate way for the individual.

The Process of Reflection

Throughout my school career I have never had much need to reflect upon my actions and how they impact others around me. However, since starting university I have started to see the importance of reflecting on your thoughts and actions in order to shape yourself into a better person.

After reflecting on different aspects of my life I have started to see many areas which require changes, for instance, time management or organisation. Reflection must be seen in a constructive way and not a critical way as you better yourself further once you process the way in which you have acted. Improving my reflective skills will help me to become a more productive student and a better person overall.

# Resource Allocation Workshop

During our first values workshop the group was split into five tables and each assigned an envelope of resources. The groups were instructed to design something that would help a new student starting at the University of Dundee. Each group pitched their ideas to the remainder of the class and the lecturer. During this our group (group two) noticed that our lecturer seemed to be getting less interested as each group stood up and talked but we thought nothing of this initially.

As the ideas were being pitched it became apparent that not all of the groups had the same amount of resources. For instance, we had various different colours of card, pens, post its, scissors etc, whereas group five had only a few paper clips and some small pieces of paper.

After pitching our ideas each group then made their helpful resource for the new student. Our group made a colour coded personalised timetable as we felt that the timetable was the most difficult aspect to figure out when starting university. Our timetable had a different colour for each module and removable tabs for the classes and events that varied each week. We based the sample timetable on my own as I had the fullest timetable.

In groups, we presented our final design to the rest of the workshop group. Just as the lecturer lost interest in the initial pitching of ideas, she also lost interest as each group presented their resource. It was apparent that the groups presenting later on were feeling unfairly treated.

Finally, Brenda gave our final designs a mark out of 10 and they ranged from group one getting a very high mark to group five getting 1/10. Brenda then went on to explain that she was intentionally acting this way and hoped that none of us were offended.

The workshop taught us that each student should be treated in the same way no matter what their situation is. Just because one person has less to work with does not mean that they deserve less attention or praise. I felt that the workshop was very effective in making us realise that we may act this way unintentionally but we should make an effort to ensure that it does not happen again. All student should be treated as equal to one another.
