D.1 Human nutrition – essential nutrients

Not all nutrients required by the body, are synthesized by the body. An example of these are the essential and non-essential amino acids. Essential amino acids are those that are not synthezied and are therefore "essential" in our diet. FYI - You do NOT need to learn the names of the essential or non-essential amino acids. Vitamins are organic compounds that are required in small amounts in order for effective metabolism. They cannot be synthesized by the body and all have ...

Using a simulation for your IA

There are several options available to you when conducting your Internal Assessment as part of the Biology diploma. These include: 1.Hands-on experiment 2.Use of database for analysis and modelling 3.Extraction and graphical analysis from a database 4.Simulation (interactive/open-ended) 5.Hybrid hands-on + spreadsheet/database 6.(Qualitative and quantitative data are valid). This posting is focussing on computer simulations. To explain what a computer simulation is and how they can be used take a look at the following video from the lawrence Livermore national Laboratory. You may not wish to watch all ...

CALP

I would like to draw your attention to a page found within the TSM that I believe to be relatively new,  Cognitive academic language proficiency (CALP). This focuses on language proficiency, specifically a conceptual framework of language proficiency as devised by Dr James Cummins1, exploring English literacy development and the social and academic barriers that limit learning for English-language learners (ELLs). Cummins introduced a distinction within language between English for social or basic survival which he referred to as Basic Interpersonal Communication Skills (BICS) and ...

The biology subject guide for first assessment in 2016 represents a significant shift, in a number of aspects, from the previous biology course and this TSM is specifically designed to assist both new and experienced teachers to build or revise their course design so that it reflects the ...

ATTL and inquiry based learning

Aproaches to Teaching and Learning (ATTL or is it ATL?) represents a progressive and explicit focus from the IB on ensuring the philosophy of the organisation is delivered and experienced within the classroom. It was launched in January 2015 and it is to be hoped that you have been made aware of the plentiful resources available within the OCC Teaching via your Diploma Co-ordinator, If not, go explore. In essence, as teachers we are encouraged to ensure the deilivery of ...

TED talks / Google Science awards and the COOLing Earth

Biology at the micro level can often feel a conceptual study of processes that have been inferred from abstract data, such as the Kreb's cycle or DNA replication. The following TED video offers a glimpse into the computer generated visualizations of the processes themselves. This video will hopefully provide inspiration as it highlights three young women winning the top prizes at the first Google Science Fair. My third video in the slow month of July is from a favourite website of mine www.labroots.com. I began ...

International Society for Technology in Education / Kahoot

As teachers we are constantly put under pressure from the school community to remain current (or ahead of the game) when it comes to implementing technology into our classroom to deliver our biology curriculum. This brings with it many issues and one way to address these can be to establish a Professional learning network. One easy way to do this can be through the International Society for Technology in Education. To subscribe to the ISTE youtube channel go HERE. The organisation has "passionate educators, leaders and ...

A2. The Human Brain

The Brain The human brain weighs approximately 1.4 kg (approximately four tubs of butter), is about the size of a grapefruit, is shaped like a walnut and can fit in the palm of your hand. Though it weighs approximately 2 percent of your body weight, it consumes nearly 20% of our calories. Brain metabolism requires a large amount of energy. Different parts of the brain have specific roles Click on the link to check out an interactive website exploring the functions of the different ...

Internal Assessment

This is not a regular post, perhaps its an anomalous one (?) But please do no exclude it. I am presently moderating Internal Assessments and I feel compelled to write on behalf of all the moderators out there, who open up a bag of scripts to find not a single word has been written on the submitted labs. Please Please Please ANNOTATE your scripts. I know that the syllabus is changing and that the Internal Assessment has had a revamp etc. However, you will still ...

How to learn with zero effort

  The brain's capacity is unlimited, if only you use it correctly (Credit: Getty Images) What is the easiest way to learn? David Robson meets a group of scientists and memory champions competing to find techniques that make facts stick... fast. As exam season is upon us and the Grade 12 exams are soon to begin, I thought you might be interested in "how to learn with zero effort". I was recently reading an article at BBC that discussed such a topic. The article discusses ways ...
