ICT is about making my life easier!


Communicating with
parents and students

Tracking Homework

The idea is to use recycling
paper to print calendars on.

http://www.re-print.me/

Print one for each class and put it up on the wall.
The teacher (or a student) can write the homework
each day.

The move to online homework tracking

1. Use TwInbox to post to twitter
2. Get RSS Feed from Twitter
3. Use twitterfeed.com to post to facebook page

http://www.facebook.com/

Communicate homework and vital
information to students and parents

Students (and parents) can access directly!

Parents want to help their son with homework?

DEC (Dept of Ed and Communities) has developed
a site to help parents know what students are doing
in schools

http://www.schoolatoz.nsw.edu.au/

There are some quick factsheets which student may
find helpful when revising. Example.


Flipping the Classroom

Flipping the Classroom

Lecture part of the lesson at home.

More engaging, interesting activities in class.

Example: Year 8 Number Plane Graphs
- Tick Sheet
- Screencast Videos (recorded using
http://screenr.com)
- Quizzes and solutions (assessment for
learning)

Flipping the classroom: Feedback

Did you like the freedom in how you could
learn in this topic?


How good do you think your understanding was of this
topic, compared to the way you usually learn?


Feedback from a parent…

“I want you in front of the class, teaching!”


Comments from students:

I hated this topic doing it on the computer and thought it
was a terrible way to learn

i really disliked learning by myself, id rather be tought by
the teacher and be given and forced to do homework. i felt i
didn't know anything for this topic


Comments from students:
When he made us choose our homework, i feel i didn't do
enough.

I liked how could work at our own pace but I need to work faster
if I want to achieve better results.

I liked how we could chose to do what subjects we did and did
not understand.

I really liked that we could choose what to do and then move on
if we know the rest.

Screencasting

Screencasting is recording a video of your
computer screen, while you are working
on it. It can also record sound.

Blogging with Year 8

Data: Graphs and Tables

Task: Decide on a topic that you are interested. Write a blog post on
Scholaris explaining why you are interested in this topic and what you
can investigate statistically.
In future posts, you will need to create and upload graphs to your blog.
Find a source of data that you can use to investigate your topic. You
may like to consider the following:
• Cars
• iPhone / iPad
• Harry Potter – IMDB
http://www.imdb.com/title/tt0926084/business
• NRL http://stats.rleague.com/rl/rl_index.html
• Cricket http://cricket.com.au/stats-scores
• Climate Change http://www.bom.gov.au/climate/data/
• Music http://www.ariacharts.com.au/
• Radio

Making it Web2.0

• Students were directed as to whose blog
they had to comment on…

• Example 1
• Example 2
• Example 3


Teaching and Learning
Applets

Applets

• This is where I started, putting technology
into my lessons

• Teacher Applets

• Students Applets

• Lets students visualise Mathematics

Applets: Examples

• GeogebraTube
• Student Applets:
– Isometric Drawing Tool
– Constructions
• Creative Commons Images: Slope

Bookmarking

Online Social Bookmarking lets you easily store
bookmarks in one place (backed up), search them
and share them with others.
http://www.delicious.com/
http://www.diigo.com/
https://bookmarks.google.com/
Store your links, so that you can find them again
Share links with colleagues – each department to
have a diigo group?

Google Earth

Runway numbers are chosen based on the magnetic heading of the runway. In
areas where the compass indication are unreliable the true north heading
is, denoted by a T prefix. Example: Sydney Airport NS Runway is on a bearing
of

Google Earth

The Pentagon (US) – Is it a regular
pentagon? “Exmouth Cape Tourist Village” –
(look slightly to the north)
Check Angles and check sides

Google Earth: 2D Measurement

To easily find the perimeter and area, you can use a Google Earth Add-on called
GEPath. This can be used to check calculations. Find the perimeter and area of your
school. How big is your school oval? Most likely, it will be close to 1 Ha.

Find the area of the sector below, by
Have students create a field diagram
taking appropriate measurements.
(by taking measurements) to work out

the area of the school, or their home.
Sydney Olympic Park).

Google Earth: 3D Measurement

Find the Great Pyramid at Giza – by taking appropriate measurements, what is
the surface area and volume? (Its height is approximately 139 m). You can also
show 3D Buildings to get a good look.

Google Earth: Parabolas

To the east of Lydd Airport, KENT, United Kingdom. See
http://en.wikipedia.org/wiki/Acoustic_mirror for information on these
fantastic structures!

Google Docs

Use google docs to collaborate for documents or
spreadsheets

http://www.offisync.com/
http://tinyurl.com/googlecloudconnect

I check homework, using my iPhone and then use
OffiSync to open the Google Spreadsheet in Excel

Microsoft Word and Maths

• Equations Suck!
• Microsoft Math
• Symbols ALT-0176

Comics

Create a cartoon / comic strip. Drag and drop the
speech bubbles, people and scenes.

http://www.bitstrips.com/

Create a cartoon yourself for a topic, or get students
to present their work in cartoon form.

Copy part of a picture

Copy parts of images or parts of your screen.

Microsoft Office > Insert Screen Shot > Screen Clipping
Snipping Tool

Modify difficult diagrams
And make the background transparent

Convert PDF Files to Word Documents

Convert PDF documents, with diagrams,
into word documents to edit.

http://www.pdftoword.com/

Example

Wolfram Alpha

How many hairs are on a human head?
Solve 2x+10=15

Students can investigate a topic, taking difficult
mathematics out of the equation – and explaining
how to do it!

Skype

• One of my students in Year 11 Extension 1 Mathematics was
scheduled to have an operation on his knee and came up with
a brilliant plan to not fall behind. The course goes very quickly
and missing any lesson can be difficult – we were going to
cover Superannuation using a GP.
• He organised with a friend to skype in from home to watch the
lesson as we progressed.
• For part of the lesson, he was sitting on a table in front of the
projector screen (well… the laptop he was skyped into).
• For the rest of the lesson, he sat in his usual seat.
• I wonder if UStream would have been an easier alternative –
although it would not have allowed him to put up his hand
and ask any questions.

Hardware

• Bluetooth mouse!!
• Monitor
• Lectern
• Eye-fi Card

Hardware

• The future of Mathematics Education…

The Samsung Windows 8 Tablet
