Psychology by the numbers

September 29, 2013

funny - math - paranormal distribution

Psychology would seem, at first look, to be one of the sciences with the least involvement with mathematics. After all, psychology is all about the mind, all about people – what does mathematics have to do with that?

Well, as it turns out, a lot! The main reason is that mathematics is of use, is that psychology has one aspect that most people don’t consider. Most think of psychology as relating to a single person, but there is one other consideration. We also care about how groups respond, and how the individual compares to the group.

To this end, we need a simple way to describe groups, so we can compare them to each other and to the individual. The best way to do this reliably is to use mathematics – and we are interested in two particular concepts – the idea of what the average value of a group is, and the idea of how much the group is distributed.

In this post, I will cover the basic mathematics you will need to describe these concepts – which you will need for your Empirical Research Activity (ERA) report that is due at the end of term 4. The mathematics is *not* difficult, and you will be able to the majority of it on your computer, by using microsoft excel (or a similar piece of software).

Avoid making ERRORS in your ERAs.

Psychology-is-fun-psychology-22111146-500-372To get the right answer, you must know how to ask the right question(s) – and psychology is all about questions  – how to ask them, what to ask, and most importantly of all, why to ask them.

Psychology will teach you about how to think – and how to understand something about the way others think. The starting point for our studies in psychology is how to approach the study of people – their behaviours &  and how the mind is related to them – in a scientific fashion. To do this, we are working toward defining and working with variables, and forming and testing hypotheses.

This process is recorded in an report called an “Empirical Research Activity” (and “ERA”), and you have to write one – just in case you weren’t paying attention for the last 10 weeks!

It’s rubber glove time!

October 14, 2012

STRETCH… SNAP.

It’s a horrible sound – the snap of a rubber glove. The implications of impending future are… not enjoyable. You are  about to have a physics exam which is the metaphorical equivalent of a rubber glove inspection for your brain. You’d better get ready!

The best way to prepare is to do enough questions. What is enough? Well, about twice as many as you think you should have done.

Reading Assignments

It is *absolutely* necessary to make good friends with your textbook. You should know everything about it, where to find information and critical facts. You must become completely familiar with it – to annotate and develop it so completely that you have extracted every last microgram of potential knowledge out of it – you should be able to turn to any piece of information without consulting the table of contents or the index.

But that is not enough. Not nearly enough – because Physics is not an “open book” subject – you can’t bring the textbook into (most) assessment tasks. (p.s. this is something to be very thankful for – you will discover (in time) that “open book” is the nastiest thing that any teacher of any subject can do to you…). You need to understand the difference between active and passive knowledge – and you *need* to make your knowledge of physics *active*

Passive knowledge is the sort of understanding of a topic you have when an expert explains it to you, and you feel that it makes sense. Active knowledge is when you can explain the knowledge that you have to someone else in a way that they understand it – and that you can use the knowledge you have to solve problems and apply it to a variety of unfamiliar contexts.

Physics Codes

Well, no class today for you – but there are still things to do. First of all, at the end of this post is the information I told you that you might want. Of course, being a physics teacher I can’t make it easy for you – I have to teach you something interesting.

Encryption is a fun mathematical process  – but it also has some very useful applications – like putting information in public view, but knowing that only those who are supposed to be able to read it can, because they have the key.

I have used a free online encrypt/decrypt tool which you can also use the link is: http://www.tools4noobs.com/online_tools/decrypt/, and I have used Blowfish/CBC/Base64. The key is our where we have our classes at Croydon…

Genetically modified lizard and alligator invades on year 10 science class. Who will survive?

April 23, 2012

For all the news and updates of genetic information and natural selection this is a must read!

This post is an evolutional changing experience, taking you from the basic building blocks of life through to inheritance then through to natural selection of monsters vs students? Who will survive?

The monster was last seen in the classroom and reports of finding eggs are still flooding the phone lines with sighting of the monster and monster egg being discovered. Let’s hope for the human race all eggs have been found and destroyed.

The monster is still at large and numerous sighing have been reported. Where it can be found no one knows, but one thing is for sure the environment it is in is suitable for the monster.
