Analog and digital technology - What's the difference? - 41 views

  • Now pretty much everything seems to be digital, from television and radio to music players, cameras, cellphones, and even books
  • we first convert the information into numbers (digits)

      It is during this conversion process that information can be lost. Depending on the process digital doesn't always capture all the gradations in analog data. Think of the difference between an analog clock (with an hour hand and a minute hand) and a digital clock (showing just hours and minutes). WIth a digital clock you can only ever see the exact minute 12:01am or 12:02am. The digital information doesn't show you the time between 1 minute past and 2 minutes past. But with an analog clock the minute hand is always moving. At halfway between 12:01 and 12:02 the minute hand will be halfway between the 1 and the 2 minute mark. If you look closely you will be able to see that it's halfway between.

      That is a really interesting point and not one i've reaaly thought about untill now.
  • People accept digital things easily enough, often by thinking of them as electronic, computerized,

  • It's not the same thing as time itself: it's a representation or an analogy of time

    To me analogue means the old and digital means modern, and i am kicking myself because I knew on the quiz that the TV was not digital but because I thought of it as a way to communicate I ticked true. I have a digital watch (fitbit) and I wear my analogue one as it does not go flat on me, the joys of digital technology.

    I actually thought similar to Susan, hence why I also chose true for the television question. I assumed ICT was any means of relaying information or delivery information, other than books or paper articles. Definitely a lot to learn regarding ICT

    What being digital means Being digital means more and more ICT devices are far more instant. They need to be mastered because this is the world we live in now even though there is still room for analog technology. ICT devices are all digital and is widely used in school and society itself.

    The teachers using effective pedagogy to help students in mastering ICT devices needs to be put into consideration in our local schools and community. The more ICT devices are explicitly taught, the more school community and activities around ICT become accessible in our classroom.

WiFi in Schools Australia - Risks. The darker side of ICT - 5 views

  •  
    This is something worth reading! Have you considered the long term effects of WIFI in the classroom on student health? Or maybe your childrens health? Watch the Video and be informed. As teachers we have a moral obligation to ensure the safety of students.

    You may also wish to explore a little further on this issue, rather than just rely on a single source. Teachers also have an obligation to be fully informed.

    WIFI - The uncontrolled global experiment on the health of mankind There are little to no studies of the long-term effects of EMFs and on a developing brains, which are physiologically more vulnerable than the adult brain for a number of reasons. With WIFI being a relatively recent technology, there is a gap in the literature addressing longitudinal studies of EMF and children. If you wish to view a recent peer reviewed study assessing just the short-term effects you may read Kuzniar et al. (2017). As we know, in our current metropolitan environment we are exposed to EMFs constantly. Markov and Grigoriev (2013) have clearly addressed some of the ethical and political issues arising from the use of WIFI technology and the unregulated global approach and safety guidelines. Grigoriev has explored this with a number of peer-reviewed studies. One that I found interesting was his article "Cellular communications and public health, 2012". From what I have read, there seems to be a consensus in the scientific community that this is an area for further research as conclusive results of the long-term effects of EMF on children cannot be found.

    Thank you for sharing I watched the video and it certainly illuminates some serious concerns not only in schools but also in our homes. I will now be looking at where our wifi unit will be situated and taking a closer look at our homes technologicial set up. This is very important to share and my children will be taking a look at this video later today. I have also read about some experiments students have done at school with a living plant that they placed near the computer and Wi-Fi as a science experiment I will see if I can find the link. I agree it is also important to research such a topic to get a broader scope of the situation. Regards Faye U1069753

    Thanks for your input Faye, The intent of my original post was not to create hysteria but to encourage critical thinking, as National Government institutions can be slow to respond to new global research...especially when it may challenge our current 'comfortable' way of life and assumptions. Cheers, u1070429

    Thank you for sharing this information. My thoughts are an education in civilised countries can't function without these devices. Children response to technology than any other educational diverse. There are more positive than negative. Using technology in the 21st century is helping our kids engage in the classroom, and our children need these devices to function in their learning to become capable and able students in future. I work in a school setting where the majority of the student's complete task using computer and iPad. We as teachers need these devices to function properly in our role as educators. Technology is fun, engaging and reliable to some extent, these methods over the years have help to improve our student outcome. Thanks, Joy

    thanks for sharing. it is amazing the possibilities students have to express their ideas and creativity with the use of ICT! only a few years ago I couldn't have imagined early primary students being able to use anything more than Microsoft word, and maybe Powerpoint to create a digital story! and now they can use an iPad and create a full multimodal text with ease! online study mummy

    This is a great app when I was on a placement I saw this in use it was a wonderful tool and the students were very engaged creating some amazing work.
  •  
    Thanks for the share. What an amazing app for students. Can't wait to show this to my upcoming placement mentor to see if we can implement it into a lesson :) Cheers, Shaz
