Ethanedioic Acid Titrations

It's that time of year where if you are in IB1 you may well be starting to think about your IA. What will you do?! I hope today's post gives you some ideas. Have you thought about working with Ethanedioic acid (HOOCCOOH) or oxalic acid to give you its more common name? Ethanedioic acid occurs as a free acid in beetroot leaves and rhubarb. Could you extract it and see how much you have? You could titrate it with a base, such ...

6/VACAF, EE/RPPF and EE/CS

(Don't you love acronyms?) I lead DP visual arts workshops, both online and face-to-face, and just before Christmas finished my last visual arts workshop of 2017. It was a category 1 and these are invariable full, packed and busy—so much to cover, so little time to do it in! As ever it was a lively and enjoyable workshop, but a couple of things sometimes seem to get pushed to the back of the line and possibly overlooked—visual arts coursework authentication, reflection on the extended ...

Preparing students in Grade 11 for Internal Assessment

By Friday, September 29, 2017 , , , , 2

The Internal Assessment represents an examination of the students understanding of the experimental programme. To this end, Grade 11 is of great importance in preparing students for the independent investigation (or II) that is most commonly carried out in Grade 12.   The experimental programme is pivotal in the teaching of Biology, illustrating, teaching and reinforcing the theoretical concepts of IB Biology. It comprises three parts: Practical activities including Applications / Skills / Mandatory labs (These can be found within 'My IB' (the platform which ...

Carrying out a good IA project

Have you stated your Internal Assessment(IA) yet? If you are a 'May session' school, this anytime from May of IB1 until December of IB2 seems a likely time that your school will carry this out with you and ask you to write it up. Which means that you need to get some ideas on what types of things you can investigate. However, the aim of this blog post is to give you some ideas for writing and carrying out a good ...

INTERNAL ASSESSMENT: THE CURSE OF OPTIMISM

THE CURSE OF OPTIMISM   Of course, I'm not against optimism.  And just to show what a positive blog this is I'm kicking off with a couple of happy songs, courtesy of YouTube ("Happy" and "Happy Talk"). Enjoy! https://www.youtube.com/watch?v=y6Sxv-sUYtM     https://www.youtube.com/watch?v=JwIddYGse9g But to be honest, this blog is not so much the curse of optimism as the curse of optimistic marking.   November IA “November schools” (mostly schools in the Southern Hemisphere) have been uploading their files and marks for the November session. Unless you only have five students, the ...

What is VACAF?!

What's VACAF? It's an acronym that stands for Visual Arts Coursework Authentication Form. (Those of you who either regularly visit the OCC or have an on-the-ball DP Coordinator will know about it). ***Not to be confused with VACAF camping holidays in France (CAF: ”Caisse d’Allocation Familiale“) PPF - That was Then There used to be a requirement for schools to submit a planning and progress form (PPF or to be precise 6/VAPPF) for each visual arts candidate whose work was selected for the IA sample. It’s ...

Uncertainties in Lab Work

It may be holiday time in the Northern hemisphere but that doesn’t say things go quiet in the world of blogging. If you are a student who is about to start on your IB Chemistry course, or, if you are a student who has yet to do their IA this post is for you! When recording measurements or data in lab work it is vital that you record things correctly, especially in your IA (that’s internal assessment to all you new ...

Mandatory Lab Ideas, 1.2, Empirical Formula

As you well know, the IB now tells us that we must carry out up to twelve mandatory labs or skills (I say up to as there is some debate whether 9.1, the application of the Winkler method is mandatory or not and the ‘single replacement labs’ occur twice, in 15.1 and 19.1). So I thought I would focus the next few blog posts on some of these mandatory labs, starting with the first on one the list, namely, topic 1.2, ...

The new IA – views from DP subject experts

The Group 4 IA is changing. For those teaching students in their first year of the DP, these changes will be taking effect now. As a teacher or a Head of School, do you know which methods and practices your school will be adopting?
