IBBio: Investigation Cycle

This is an attempt to capture the internal assessment descriptors (for the new guide) in a format similar to the MYP’s Experimental Cycle and Design Cycle diagrams. Click here to download a higher-quality .svg file for poster printing.

Updated Turnitin GradeMark QuickMarks

Here’s a new set of Turnitin GradeMark QuickMarks I have saved to More IA resources on the IA pages here.

My QuickMarks

They correspond to the self-assessment codes in the rubric and checklists I use with students, and will only work if your school subscribes to the full Turnitin WriteCycle suite. Each comment has a check or cross, a title and some guidance or further description in the box. You can add your own comments individually to each as you use them in student work.

Some others:
If you make changes to the QuickMarks and Sets yourself, be sure to save them periodically by exporting them to your computer – there is no ‘are you sure?‘ popup when you hit ‘delete set’ by accident
If your school is already using Turnitin, it is well worth asking for access to the full suite of tools. They have a discount for IB schools and you can give quality, paperless feedback.
The presentation below outlines how these can be used (you don’t need to have Moodle):

Excel Graphing Screencasts

These two videos are for my classes, made using the free screencast tool ScreenCast-O-Matic.

The first is for my IB Bio group for setting up a graph for a complex set of data, adding extra datasets, error bars and formatting. The second is a similar video for a simple Physics investigation in Grade 10.

Hopefully they are helpful as you can go back and re-watch important bits as you do the write-ups.

If anyone knows of a decent way to add best-fit curves (lines are easy) to datasets, please let me know!

By JoVE, it’s Science on video!

They also have a sister site here:

It’s a blog/youtube site for Science only, and has some decent videos sorted into categories. I’m still trying to work out how to save or embed these videos, but it’s well worth a look. Great for introducing up-to-date Science topics in class.
