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.

John Oliver: Climate Change Sketch

This funny (but sweary) John Oliver sketch skewers the non-debate on climate change.

“The debate on climate change should not be whether or not it exists, but what we should do about it.” 

With 97% agreement from scientists on the human cause of climate change, are the media skewing the debate with 1:1 representation?

This is connected to the Greenhouse Effect topic resources. Don’t play it in class without listening first – there is some strong langauage.

BioNinja: App & Website

The Future of i-Biology

iBiologyStephenThis post is in response to a number of emails, comments and other messages I’ve received recently regarding plans to update the site. 

A new IB Biology guide has been released for first teaching in summer 2014 and first examinations May 2016. It outlines significant changes to the course, especially in terms of internal assessment and examinations and the prescriptive nature of the content coverage has shifted to be more open-ended.

Much of the content-based work on here will remain useful, though will need to be reorganised (eventually). I will leave the IA support stuff up here for the coming year and will work over the coming academic year to update the site as far as possible. I will likely remove a lot of IA-related content, as we are to expect significant teacher support material on the OCC, and that is where teachers should be making their first stop for reliable documentation.

Personally, my load has shifted a lot in recent years. It has taken about seven years to build this site and all of its assets, and I am happy to continue to share them freely. However, most of my time is now taken up with being an MYP Coordinator and teaching MYP science classes, as well as being HOD for science and having larger groups of students with no lab support. My IB Biology class are currently in IB1, and I will keep them next year on the current guide. I also have family, MA studies and other commitments, so will not likely be able to revamp the presentations in the immediate future. Please give it time and use your judgment as to what is useful and valuable if you are starting teaching of the new guide this summer.

Update: October 15 2016

My load has shifted again, and I am now Director of Learning and MYP Coordinator, still at Canadian Academy, Kobe. With no teaching load and being stretched very thin for time, I am less likely than before to make any major updates to the site. I will keep paying for site hosting as long as it proves useful to teachers and students. I will start to prune some pages where possible.


Biology4Good Charity Project Update

Biology4Good - click to make a donationWe have now passed 3.4 5 million views on the site, with over £4 5,000 in charity donations made through Biology4Good. If you donate £20 or more, you can have access to a folder of all the editable resources I still have. These donations and the ability to support a selection of my favourite charities are significant motivators for continuing to update this site, so thank-you for the ongoing support.



Update: June 7 2014

It was sad to see John Burrell’s announcement that he plans to close Click4Biology, as he has given a great service to students and teachers through his online notes over the last decade. However, his reasoning is sound – the change in the subject guide to move away from such defined assessment statements makes producing these resources more challenging. At the same time, the text resources, such as Allott & Mindorrf’s Course Book, with it’s online edition, have really upped the quality of what is available to students from the publishers.

Looking at this year’s statistics on, there was the usual big spike around the May exams (around 10,000 on peak day, compared to 2,000-4,000 on regular days), but it was far below the record of over 20,000 last year. From the discussions around #IBBio on twitter, it seems that much of the review traffic has swung towards BioNinja’s apps and notes that are set up for mobile learning and review. Again, this is a great service to students, and there is little point trying to replicate that.

I will think carefully over the coming year about how this site will continue, and it will likely be more streamlined in terms of course content but with more organised ideas for teaching and ed-tech.

If you have any suggestions, please leave them in the comments below, or find me on Twitter (@sjtylr).

IB Biology Orientation

Welcome to the 2013-14 School Year!

Here is a quick overview of for new and returning users – teachers and students – and I wish you all the best in your studies. Please note that this is not an official IB product and so should be treated with due caution. I do my best to keep it current and accurate, and appreciate constructive feedback.

I am active on Twitter, sharing ideas and resources using the #IBBio hashtag.

The purpose of this site

Follow me on Twitter

This was designed as a support site for my own students, and hosts all of our class resources: presentations, links, videos and more. It is intended to allow for more student-focused teaching in that we do not go through every presentation as a lecture, this resource acts more as a student text and set of provocations for discussion and inquiry. Having said that, we are preparing for a terminal examination, so there is significant content to prepare students.

I have students keep track of their progress in their own personal GoogleSites and we have focused sessions on some topics and subtopics where needed. We use Quia extensively for pre-assessment and practice, and all tasks are based around model exam questions, data analysis, discussion and lab work. There is a high degree of cooperative learning in the class. Students have their own copy of Allott’s Study Guide and we have some Course Companions in the class.


By using the tabs at the top of the site you will find pages for all Core subtopics and all of the options and HL topics that I have taught. I do not have (nor plan to have) content for the remaining options.

The front page of this site is a blog, which is periodically updated with resources, news or discussion of science and education. Follow it, if you wish. I appreciate comments and sharing through Twitter.

Biology4Good Charity Donations

Pay It Forward

This work is open and shared so that others can benefit and save time, focusing on good teaching and learning instead of having to reinvent the wheel. I do not charge for access, though I really appreciate it when people make small donations to one of my chosen charities through my JustGiving page Biology4Good. Pay it Forward – please estimate the time and money you have saved by using this and give a small proportion to charity. Find out more here. Donors giving GBP20 or more (and leaving their email address) will be given access to a DropBox folder with more editable powerpoint files.


I moderate all comments. This is a site for students, so please behave accordingly. I do appreciate questions and suggestions for corrections.



Technical Issues with SlideShare

Some of the SlideShare presentations have been displaying poorly recently, and many of the links have stopped working from within the presentations. This seems to affect the presentations which are more than a couple of years old. I have re-uploaded a couple, which might help. Hopefully SlideShare will fix their issues soon, as with over 90 presentations, 40 documents and lots of links and embeds it is too big a job to start from the beginning.

EDIT – I’ve contacted SlideShare and they say they aware of the problem and are acting to fix it. 

Solutions for now:

  • Use the images in the presentations as keyword hints for searches
  • Follow links on the subject content pages here
  • Download the presentation and follow the links (but stick to the acceptable use guidelines and do not re-host on other internet servers).

If anyone knows of other good presentation servers, please let me know. SlideShare works well with WordPress – Prezi, Slidrocket and others cannot be embedded here, due to the WordPress security settings regarding Flash.
