Green screen in iMovie 09

A Green Screen made from wide bright green poster paper for classroom displays




This week my class have been film making and they are really enjoying the experience. I recapped the use of story boards and after demonstrating the use of Windows Movie Maker (and warning them that it might crash constantly) I pointed them towards this wonderful site from the BBC called me and my movie for extra tips on camera shots, lighting, story boards and editing.

As the class worked on their story boards I noticed that they all wanted sfx such as scenery and sound. That's when I remembered that iMovie'09 on the Mac can put Green screen effects onto a movie. What this means is that you can change the background of a video clip to any other background as long as the first clip is shot in front of a green screen. I thought that obtaining a green screen would be expensive but I decided,
'Why not try bright green poster paper?'
 I did and the effect has been more than I could have hoped for. Here's a short video demonstrating it. If you want to do this yourself then make sure you have a Mac with iMovie'09 installed and follow these instructions or watch my video on this post.

How to use proxy setting with Linux Mint

The dreaded proxy server has reared its head again. If you read my post about Linux OS for old tech you would have found me advocating Ubuntu, Elementary and Linux Mint. Unfortunately, I have found Linux Mint to be problematic if your school server uses proxy settings to get online. Ubuntu and Elementary also require changes to the network settings if you use a proxy, but this only involves a simple change in the Network Settings panel. This doesn't work in Linux Mint, the settings can be entered but will not remain saved.

So, here's the 'how to' courtesy of the askUbuntu Q&A section - if you're not keen on using terminal commands I suggest you either don't bother using Linux Mint and stick to Ubuntu or Elementary (or any other Linux distro) or swallow your fears and give this a go.

Use terminal to open /etc/environment using a text edit app as superuser - e.g. interminal type sudo gedit /etc/environment     (enter password when asked)Add the following line…

My latest lesson observation feedback

This was the outcome of my latest lesson observation - I received Good with Outstanding features (whatever that actually means). The form is based on the 2013 Ofsted criteria for a whole school observation, such criteria is not meant to be used to grade individual lessons so why are schools doing exactly that?
To achieve an Outstanding grade on this form I would have needed to do the following in the length of time the lesson observation took place.  Almost all pupils make rapid and sustained progress across the curriculumMarking and feedback from the teacher and pupils is frequent and of consistently high qualityTeaching of reading, writing, communication and maths is exceptionalUse of well judged and often imaginative teaching strategies that match individual needsTime taken to develop skills in other subjectsAppropriate and regular homeworkNow to pick some of these apart. No teacher can possibly be expected to ensure all pupils make sustained and rapid progress across THECURRICULUM

Marking in primary schools is verging on the ridiculous

Marking in primary schools used to be done with a red pen or whatever colour happened to be closest at hand. I've even marked in pencil once, but most of that marking was rubbed out by the children. What's happened now however has been steadily creeping in over the last few years - red pen is seen as bad, a terrible colour to mark with. Children view it as negative even if their work is correct. Red is now a banned marking colour in many primary schools across the land and has been replaced with a plethora of colour coded marking schemes, all followed to the colour due to the ridiculous nature of some primary school marking policies.
