To ASCII or not to ASCII?

Wrapping my head around how best to deliver content from the Digital Technologies Curriculum continues to keep me awake at night. The most recent dilemma being just how deep to dive when it comes to explaining the complexities of data transmission to Year 5, whose eventual assessment task will involve them telling the story of data from user input to output via a network printer. These students have little to know prior knowledge to build on, and while in subsequent years students will bring more with them to build on, right now I feel like an alien speaking in clicks and honking sounds.

What on earth is she talking about?

The content descriptor being addressed is:
Examine the main components of common digital systems and how they may connect together to form networks to transmit data.
​(Year 5-6 Digital Technologies Knowledge and Understanding)
The elaborations provide the following information:

While the elaborations do break this down a lot more, it is still very open to interpretation. Getting Year 5 students to describe the process in Laymen's Terms didn't seem ambitious enough. Why not dive a little deeper? It seems reasonable to at least mention it........right?

Sometimes teaching is like performing a dance...

The fact is that not all concepts are the most engaging or to easy to communicate. It can be a little like performing a complex dance in front of a panel of hyper-critical adjudicators. Stumble...and you lose them. Dazzle them...and they won't take their eyes off you. The difference here was that instead of performing a dance I was trying to explain a very abstract concept in a simple way.

And so it began....I opened by stretching out the acronym, sashayed into examples of common letters and symbols, pirouetted around  the involvement of the CPU, pliéed into the role of binary before ending with a bow and an example of data transfer in pixel maps.

At this point I luckily had some "ah-ha" moments in the audience because it connected with our previous data transference lesson.

I took a breath.....not a total flop.

Having some fun with it: ASCII to Binary Chinese Whispers

So at the end of my dance at the front of the classroom I was happy to see the majority were still with me, although there were some very big eyes in the audience. At this point I always find getting the kids up and acting out processes has a big impact. So we played a sort-of Chinese Whispers in groups.

Roles included:
  • Keyboard
  • CPU
  • Software 
  • Monitor 
The members of the team stretched across four points in the classroom.

The keyboard decided on a letter which they sent to the CPU in ASCII. The CPU used an ASCII to Binary converter to produce a Binary Code which they then passed to the Software. The software created a pixel map of the letter before passing it to the monitor to hold up for the keyboard to confirm on the other side of the classroom with a thumbs up.

After the first round, it became a little bit competitive and the teams wanted to then race each other. It turned out to be a good brain break and provided the children with a more physical representation of the process. 

What do you think? Should kids in Primary School be learning about ASCII? How deep do we go? Leave me a comment! I'd love to hear what others think.

Powerful Learning Environments

22/2/2017

Powerful learning environments occur when three key elements connect: effective teachers, engaged learners and meaningful content. I have created the picture below to visualise this thinking. 

In my opinion, the adjectives are important here. A powerful learning environment doesn't just happen when you throw together teachers, learners and content in a blender. The creation of a powerful learning environment relies heavily on the individual qualities of these elements.

Effective Teachers

There is so much evidence and research which proves that great teachers get great results. I like to think of teachers as "master learners" and in being these masters, exhibit all the characteristics of what makes a great learner. Effective teachers are mindful about the needs of their students. They are constantly innovating, reflecting and seeking to improve their practice. 

Engaged Learners

While student engagement is influenced by many external factors and systems such as environment, biology, content and teacher effectiveness, there is a certain internal engagement factor that each student has. An engaged child is more receptive to content and instruction and so this contributes to a powerful learning environment.  

Meaningful Content

Back in my schooling years, I remember sitting in my childhood classroom thinking "when will I ever use this?" There are still children thinking the same thing. Designing authentic and deep learning opportunities are more common these days. And while higher bodies dictate curriculum outcomes, making the delivery and application of content meaningful is something we can influence - and in doing so make it more powerful. Being clear about the skills and knowledge being developed with students can help them to see value in a lesson.

Data Transmission: Using the Collaboration Space in OneNote Class Notebook to teach children about how computers transmit data to peripherals

20/2/2017

Over the last few weeks, I have been working with Year 4 and 5 students to develop their knowledge on hardware, software and peripheral devices. Last week we cracked open an old desktop computer to explore its internal components. Most found this very interesting. ​

This week I wanted to explore how a digital system communicates with a peripheral device (such as a printer). We started discussing binary and how 1's and 0's represent on and off electrical states. Australian National Curriculum in upper primary requires only a rudimentary understanding of binary, so to help demonstrate this process we completed the following activity using the Collaboration Space in our OneNote Class Notebook.

Students worked in teams. Half of the team pretended to be a "computer" with a picture to send to the other half of the team who were the "printer". The computers recorded the picture in the Collaboration Space as 1's and 0's. The printing team interpreted the code and recreated the picture on the other side of the room using a laminated grid and cards. Both parts of the team took a photograph of their image to check their work. 

I found this worked really well and promoted a good conversation about data transmission.

My tips for conducting research in schools

16/2/2017

0 Comments

 
I was flattered to be invited to return to ISQ recently to speak about my experiences in Action Research. Last year, along with two of my colleagues, I conducted an inquiry into how to best leverage 1:1 devices in upper primary classrooms and investigate the impact they had on pedagogical approaches and outcomes. 

The Action Research process is flexible, but in order to maintain momentum, researches need to commit to the ongoing process. Here are my tips to getting the most out of research projects in schools:
  • Maintain regular team meetings - regular team meetings keep team members accountable and help push actions forward. 
  • Work within a shared space - my team found a shared OneNote Notebook a fantastic place to document our findings, keep reflective journals, keep meeting records and share materials.
  • Base your research and direction on data - It's well and good to research something of interest, but researching a solution based on a need identified through collected data is more valuable and will have a greater impact in your school.
  • Set aside time for relevant academic reading and connect with other teaches online - there is a world of experience out there. Chances are that you are not the first teacher to experience a particular difficulty with something. There are great teachers filling social media spaces such as Pinterest, Twitter and Instagram with great ideas.
  • Maintain an open mind about the direction of your inquiry - As you complete research cycles, post-data may change the direction of your inquiry. Be open to heading in a new direction and making new discoveries. Planning the road ahead can sometimes make for a boring journey!
  • Promote your work and findings - Teachers rarely promote the great work that they do. Sharing your experiences can engage others in your research and pique curiosity.
  • Use Action Research as a vehicle for change - conducting research provides you with data that can be used as evidence for proposals and changes in practice

Have you done any research projects in your school? Share your experiences below! Feel free to contact me if you would like to discuss conducting research in schools.
