In 2018 Paul spent considerable time developing his knowledge and understanding of how block coding worked and used this with his 5/6 class to program Sphero robots. In 2019 he has continued to extend and develop his knowledge of programming, using the Parrot Mambo drones with his class.
This Digital Technologies unit involved students extending their knowledge of block coding, learning about drone safety, how to manually fly the drones, understanding and using the Tynker app, and programming the drones through an obstacle course. Students also had to use a variety of interpersonal skills to successfully work with a partner during the program.
As with most technologies being used for the first time the drones required a significant amount of persistence and problem solving. In preparation Paul did taught himself how to use the drones ensuring he knew some of the issues students would face when working with the drones. The students demonstrated considerable problem solving skills and a good understanding of block coding to achieve the end goal of moving their drones through a series of obstacles.
Comments made by the students included:
“We had to make sure we put in the correct information to make the drones work, things like height, distance and time”.
“I really liked making the drones flip and do 360 degree turns, being able to program the drone was fun”.
“It was fun working with a partner to program the drones. I enjoyed interacting with the drone rather than just sitting at a computer”.
“We had some problems connecting to the drones sometimes but most of the time they worked well”.
“It was fun flying the drones but it was a challenge to program them correctly”.

The DEC Intranet provides some useful resources around STEM including information about STEM learning and its importance, STEM learning programs and STEM learning resources.
One of the resources is a best advice paper titled Putting STEM education into perspective. The purpose of this paper is to clear up misconceptions about STEM education. I have summarised the key points.
STEM is not new emerging in the 1990s in the U.S.A. Much as it is now, the driving forces were economic and political. The original focus was science and maths. Technologies evolved within this framework in the later 90’s.
There is speculation about what STEM actually is. Some see it as only pertaining to an interdisciplinary focus (Breiner, Johnson, Harkness & Koehler, 2012). While The National STEM School Education Strategy states: STEM education is a term used to refer collectively to the teaching of the disciplines within its umbrella: science, technology, engineering and mathematics; and also, to a cross-disciplinary approach to teaching (Education Council, 2015, p.5).
The paper highlights real world examples of connections between the each. Examples provided include connections between two subject areas to all four.
At the centre of the figure is integration across the four areas of science, technology, engineering and mathematics. Again, using the telescope example, current construction of the Giant Magellan Telescope in the Chilean Andes moves beyond technology to become a mathematical and engineering feat, given its seven 8.4m mirrors and aperture of 24.5m. It is predicted that this mega-telescope and others will increase our current understanding of the nature of the universe exponentially (Spinks, 2016).
In more recent times STEM has been seen as seperate to its four foundational areas making STEM a separate entity. The rhetoric communicated around this view is that unless children or students are building, designing and solving problems they are ’not doing STEM’.
STEM as a seperate entity is often accompanied by the idea that the pedagogy is the focus and this will automatically allow students to learn, for example problem solving, problem based learning, collaboration and group work. Missing from this thinking is a focus on ‘traditional’ content knowledge.
There is no educational premise for STEM being a separate entity (taught isolated from the weekly maths, science and technology lessons). When taught as a separate entity the risk is focusing on the associated pedagogies with little thought for content knowledge which is required to successfully explore authentic problems.
While these pedagogies are effective, content discipline knowledge is a requirement, as is teacher direction and guidance. In actual fact, using these pedagogies appropriately requires considerable skill and teacher expertise (Rosicka, 2016).
What does this mean for our practice?
STEM should not be viewed as a new/separate subject to teach.
Depending on your previous practice you may need to adjust your teaching:
to create clearer, practical links between the STEM subjects
to provide tasks that allow students to apply content knowledge from one or more STEM related disciplines to authentic problems.
A lesson of building, making, problem solving, problem based learning (at any year level) is not STEM without the underlying scientific, technological, engineering and mathematical principles being explicitly identified and applied.
We have identified a room in our school which staff and students refer to as the “STEM room”. We must be careful not to associate this with where STEM is taught. It is one of the many spaces STEM can be taught in our school.
We should not lose sight of the importance of content knowledge, careful teacher guidance and explicit teaching. While Hattie can often polarise educators I think he explains this well in the following video discussing why pedagogies like inquiry based learning can fall down without the supporting content knowledge.
We should continue to develop a deep understanding and knowledge of:
the science, technologies and maths curriculums and how to teach the content effectively
“Most questions are safe, that is they surface what is already seen or understood, they lead to regurgitated ideas and opinions. In other words, most questions people ask really surface what is already known. Top performers however, they ask questions that go deep. They ask questions that move us from automatic, reactionary thinking to deep thinking, they ask questions that inspire creativity, fuel passion and lead to profound ideas. Most importantly they ask questions that spur people into action.” Mike Vaughan, 2015
The success of a good answer relies on the words we choose. For example, when confronted with a challenge consider two ways you might look at the problem, 1. What should we do? (narrowing possibilities) or 2. What could we do? (widening possibilities). Mike Vaughan, 2015
Do the majority of questions we ask in the classroom fall into the safe category? That is, questions we know the answer to, with a high chance that some or all students will also know the answer. It isn’t that we shouldn’t ask safe questions, they are important and provide us with an insight into the level of knowledge students have. However, if these are the only types of questions we ask are we doing a disservice to our students?
How will they learn to apply their knowledge to complex problems?
How will they use their knowledge to critically evaluate?
How will they use their knowledge to create?
How will they know it is ok to ask a question, which they do not know the answer to?
This article is written by Microsoft who supply laptops to schools so I will take it with a grain of salt that they don’t see the value of mobile phones in the classroom but I will say it does reflect my experience. I see little use in my HPE classroom for student mobile phones when we have access to school iPads and 1:1 laptops. My general experience is that across the school day phones distract considerably more than they influence learning.
After teaching students about sound and how it works set students the challenge of amplifying your phone. Have students work in groups with each group presenting their ‘speaker’ to the class using your phone as the audio source.
What materials worked best?
What shapes worked best?
What size works best?
What other things need to be considered to improve amplification?

Rube Goldberg was born in 1883. In 1904 he graduated Berkley College as an engineer which eventually gave way to him becoming a sports cartoonist for the San Francisco Chronicle. He continued as an editorial cartoonist for the New York Sun and his fame came from a fictional character he created, Professor Lucifer Gorgonzola Butts. Through this character he would illustrate complex inventions later to become known as Rube Goldberg machines.
A “Rube Goldberg Machine” is an extremely complicated device that executes a very simple task in a complex, indirect way. rube-goldberg.com

“Do Ink’s excellent Green Screen app is a fantastic addition to the amateur film maker’s armory.” – iPad Insight
“Single best green screen app ever produced…” – iPadEducators
This app is on all of our classroom iPads and combined with the green screen and lighting kit in the STEM centre provides an opportunity for students to create some great videos.
Recording lessons can be a powerful way to support student learning. However before implementing any new technology, especially those that require student engagement outside the classroom certain questions should be asked:
Is there a benefit for my students?
Do I want to invest some time in this?
Is the technology going to work in my school environment?
If not who can help me make it work and will the time it takes be worthwhile in the long term?
Is the technology available to my students at home?
Is it easy to use and access?
Recording a lesson should be no more complicated than opening
the software, pressing record, going about your lesson in exactly the same
manner as any other lesson, press stop recording and then uploading the
video to a place for students to access.
Five reasons to record your lessons:
Absences: Student absences are frustrating. There is nothing worse than teaching a critical lesson, outlining a new topic or explicitly teaching a new concept and one or more students are away. If the lesson has been recorded then the student has the opportunity to catch up on what they have missed without the teacher having to spend time during the next lesson ‘catching the student up’. The link to the video can also be sent to the parent via email or txt message.
Note taking: If students know they can access a video of the lesson at any time they do not need to spend time taking notes during the lesson. Removing the need for note taking allows students to focus on the lesson being presented rather than rushing to keep up with note taking.
Teacher feedback: Recording lessons can pick up the discussions that occur during lessons (a good microphone may need to be purchased). This allows the teacher to hear who is responding and their understanding of concepts. It also provides feedback to the teacher about the lesson – How did it go? What would I change? Was my questioning effective? etc.
Flipped learning: A growing trend in education is flipped learning. This requires the teacher to 1. create a lesson (or part of) outside of normal lesson time or 2. find a video made by someone else and ask students to view the video for homework reducing the time needed in class for explicit teaching of the concept and more time for application and discussion of the concept.
Revision/parent involvement: A series of lessons recorded on a topic provides a resource for students to look back on to revise for an assessment task or test. If parents are made aware of how to access recorded lessons they can support their child at home to access them. This is true for younger students whose parents may wish to sit down and help them strengthen a concept.
You may not be someone who wants to record every lesson (I don't). But you
may want to record the odd lesson or section of a lesson every now and then.
For example a 15 min explicit teaching lesson in maths or a 10 minute
procedure in science or a 5 minute grammar rule in English.
If it is something you always teach then the video becomes a resource
you can use in the future. Having the skills and tools to do this
is a valuable addition to your teaching strategies.
How can I record lessons?
Screen record on the iPad using a new iOS 11 feature
iOS11 has the ability to screen record your iPhone or iPad which allows teachers to create recorded lessons using these devices. iOS11 saves the video into the Photos app. There were some bugs initially with the audio not working when the video file was uploaded to sites like You Tube or apps like iMovie. This bug has been fixed in iOS11.2.
ShowMe developers say: ShowMe allows you to record voice-over whiteboard tutorials and share them online. It’s an amazingly simple app that anyone can use. ShowMe is a very simple and easy way to get into recording lessons. I have used this app previously for this purpose and it is best used with a stylus to write on the iPad screen. Creating a ShowMe account allows you to upload your videos to an online account providing a place for your students to access the completed lessons. You can also access other teacher’s ShowMe lessons in a variety of subject areas. Lessons will also be saved in the app without having to upload to the ShowMe website.
Educreations is another whiteboard app that I have used to record lessons and works in a similar way to ShowMe. It offers more functionality and options but is essentially the same idea. It allows you to record lessons and upload them to the Educreation’s website to be accessed by your students. Educreations also has its own You Tube channel which allows you to access other teacher’s Educreation videos.
As well as creating lessons on the iPad you can also create lessons on your computer once you have logged in with your account. This does require writing with the mouse which I find annoying (easier with a stylus on the iPad or a touchscreen laptop).

Quick Time (Mac)
Quicktime is the video playback app available on Mac which has a function allowing screen recording. If you own a Mac then Quicktime comes as part of the operating system and does not need to be downloaded. If you own a Widows PC or laptop you will need to download Quick Time although it is worth noting that Apple have dropped support for Quick Time on Windows past Windows 7. Apple says: QuickTime 7 is for use with Windows Vista or Windows 7. If installed on other versions of Windows, it may not offer full functionality. You can download Quick Time for Windows 7.7.9 here.
There are many web based screen recorders like Screen Cast-O-Matic. I have used the free version of this (15mins free recording) and it works well. The paid version is also relatively cheap, a one year subscription costs $1.50 per month or a three year subscription costs $1 per month.
This app costs AU $30.99 (US $19.90 for Windows or Mac). While it is expensive compared to other apps it offers some great functionality for those serious about screen recording lessons. Download Ink2Go here. I have not had the chance to use the app to record a full lesson but have played with it and it seems to do a good job.
Ink2Go website says: Ink2Go is an extremely simple yet powerful screen annotation and recording software. You can easily write on top of any other application that is currently active on the desktop, even on a running video. You can then save your annotations as an image file or even record the whole session as a video for sharing. It is a useful tool for presenters to communicate and share ideas during a live session, for educators to create effective video tutorials.
Flipped learning may not be something you want to explore and recording some or all of your lessons does not mean you are ‘Flipping’ your classroom. If you are interested in finding out more about Flipped learning visit the Byron Bay High Math faculty blog which has detailed information about how they have applied the concept of Flipped learning.
