Software
For this core topic, the syllabus requires students to:

·          define and describe a software system
·          explain the purpose of a software system

·          distinguish between types of software
·          select and justify the use of software for a given situation


They may already have an understanding of software as it would have been touch upon during the Hardware topic as a way of distinguishing between the two. I believe this video will allow students to again gain an understanding of both types of software and be able to accomplish the syllabus requirements. The video may be an intro to a more in-depth activity to ensure understanding is acquired

Robotics and Automated Systems
I think this topic can be of particular interest for school students as robots are not only know from a technical computing point of view but are part of children’s lives from a young age in popular culture and fantasy. There are many kids TV shows and movies that display robots as an amazing thing of the future that we can interact with and can help us accomplish tasks. These could be mentioned to start off the unit and get students interested but relating it to things they know and enjoy such as star wars robotic characters, the robot you can buy in the Sims game to do the house work, I Robot movie, The step ford wives, inspector Gadget,  The Terminator, The Jetsons, Transformers etc. It is also part of the syllabus to:
- investigate the image of robots from Hollywood and the scientific community
Therefore discussing some of their favorutie TV show/movies is quite relevant.



The following video gives a really quick, uncomplicated and easy to understand history of robotics which is a syllabus dot point. It could be turned into a quiz where students need to try to remember or write down as many points as they can about the video and then get into groups and share their notes. The group that covers the most information provided in the video gets a prize. Students at this age are very competitive; especially boys so turning activities into competitive games, tends to really motivate them in class.

People
The aspect i found most interesting about this lecture was the computer industries increasing lack of popularity to women. I could relate to that as i have always found that computer related subjects or tasks are one step ahead of my comfort zone or level of capability and find myself asking the boys for assistance continually. I think this may have developed from my own self efficacy in relation to computing. I already believed i was incompetent before trying to master the skills. This made me interested to find out why this is common to women in general not just myself.
A research study was initialize by the Associate Dean for Undergraduate Computer Science Education at Carnegie Mellon University, and Jane Margolis, a social scientist and expert in gender equity in education, suggested the main issues discovered in interesting and retaining women in computer science were feelings of an experience gap, confidence doubts, interest in curriculum and pedagogy, and peer culture.
I believe there needs to be more done from an early age to motivate girls in computing. As high school teachers we don’t get them until year 7 at which point they may already have developed a low self efficacy for computing, however with certain positive reinforcement interventions such as afternoon computer clubs or class activities that have a particularly appealing subject matter to girls may help to improve their low self confidence or lack of interest in the subject.

Networking Systems
In the presentation for this topic i found the video very informative and great for a stage 5 class. The video can be stopped and start to allow for discussion and sections can b skipped or saved for another lesson if the teacher did not want to show the entire video. I think this topic can be quite dry and i found it very difficult to understand when we learnt it last year. Many students like myself find it hard to picture something that cannot visually be seen like a network. For this reason i think the more visual explanations the better and thus, videos are a good start.


The text book Multimedia: Making it work by Tay Vaughan is a fantastic resource for this topic. It provides easy to understand and detailed information on everything network related including:

A communications network

·          nature and role

·          advantages and disadvantages of a communication network such as
        sharing of peripheral devices
        application programs
        data
        security of information
        access to databases

Protocols such as

·          TCP/IP

·          IPX/SPX

·          netbui

·          appletalk


Data transmission modes

·          simplex

·          half duplex

·          full duplex

Data transmission rates

·          baud rates

·          bits per second

Data transmission media

·          wire

·          wireless

Types of networks such as

·          Local Area Network (LAN)

·          Wide Area Network (WAN)

·          Virtual Private Network (VPN)

Client server and peer-peer networks

Components of networks such as

·          servers-file sharing servers
·          print servers
·          mail servers
·          workstations
·          hubs
·          switches
·          routers
·          gateways
·          repeaters
·          bridges
·          network interface card
Security of information

·          storage

·          backup

·          security
Network topologies including

·          star

·          ring

·          bus

Network operating systems

·          purpose

·          management such as establishing users and groups users and groups, security permissions and policies and profiles, use of compression technology


All of the above are direct “learn abouts” from the stage 5 syllabus for this option topic. And all are covered in the listed text book.

This week we had one presentation on Artificial Intelligence, Simulation and Modelling.

This was great. I would have had no idea what artificial intelligence or simulation before this lesson. If someone asked me to take a guess at what it was I would have probably said something that the CIA would use or government spys to gain information or help them in covert missions. But I was really surprised to learn that it is in our everyday lives, video games, computers etc.


I thought the lesson was fantastic. The teachers made a point that there would be a quiz so they needed to take notes, this made us all listen and write stuff down. We then did the quiz which was quite tricky but were able to get the answers we missed during the class discussion. The teachers also asked for answers from each table so it wasn’t the same student always answering the questions, everyone was involved. The conclusion of the lesson was awesome. We all had to log on and play a simulation game where we either had to drive a car or fly a helicopter, it was really hard but so much fun and a great way to tie up a lesson that was heavily content based with something that was still perfectly relevant to the topic but also really fun for the students. Its almost like a reward for trying hard in the quiz etc. I really loved this lesson and if I am teaching this topic I will definitely integrate these methods into some of my lessons.


The link is the trailer to a fantastic Steven Spielberg film called Artificial Intelligence. It is set in the future where the possibilities of Artificial Intelegence have progressed. The story is about a boy, a robotic boy who is programmed with the ability to love.  I think this could be a great movie for the students to watch as they will be interested since it’s by Steven Spielberg. It may help them to start thinking about artificial intelligence and how it can and can’t or shouldn’t work.


Past, Current and Emerging Technologies


I am really interested in new and emerging technologies and the considerations that come with it. I remember for the trial HSC I wrote a response on obsolescence. Much of what I wrote I still remember and I think it is really important to know. I could discuss some of these points with a class and see what their opinions are.



“With new and emerging technology obsolescence is a huge issue.

Planned obsolescence could be seen as ethical in that the world is fast passed today with new and emerging technologies. Planned obsolescence forces the public to keep up with the rest of society. We also greatly rely on our economy and the workforce. And important segment of that is sales and goods and services. To prevent the economy from falling into recession, society need to continually be requiring goods and services and be purchasing them.

It becomes unethical when designers and marketers deliberately over use planned obsolescence to generate massive long-term sales and financial profits.


Designers also need to consider the environment. If they are going to adopt planned obsolescence into their designs they need to ensure the resources and materials used to continually make the products do not have negative effects on the environment. Resources need to be infinite (water, wind, air, trees) and materials biodegradable or environmentally friendly, so that they do not add to land fill. It would be unethical for designers to use finite materials and resources (coal, oil, fuel) as they would be making more products than necessary which harming the environment. Looking after the environment can draw the line between ethical and unethical behaviour. Our environment is of huge concern today and designers need to consider this in our changing world. we all leave our own environment footprint, so we should make it a positive one.” extract from my year 12 essay.
