COMMAND TERMS
These command terms indicate the depth of treatment required for a given assessment statement. These command terms will be used in examination questions, so it is important that students are familiar with the following definitions. They are used throughout the syllabus to let you know what you are expected to do with each piece of information. PLEASE learn them early and get a head-start!
EXAM TIP
If you know the meanings of all the command terms, then you know what the examiner expects you to do – no more, no less. Pay attention to the number of marks available for that question and make at least that many relevant points (better to try to make >2 extra points)
Here are the ESS Command Terms.

NATURE OF THE SUBJECT
As a transdisciplinary subject, environmental systems and societies is designed to combine the techniques and knowledge associated with group 4 (the experimental sciences) with those associated with group 3 (individuals and societies). By choosing to study a transdisciplinary course such as this as part of their diploma, students are able to satisfy the requirements for both groups 3 and 4 of the hexagon, thus allowing them to choose another subject from any hexagon group (including another group 3 or 4 subject). Transdisciplinary subjects therefore introduce more flexibility into the IB Diploma Programme. The environmental systems and societies course is offered at SL only.
The prime intent of this course is to provide students with a coherent perspective of the interrelationships between environmental systems and societies; one that enables them to adopt an informed personal response to the wide range of pressing environmental issues that they will inevitably come to face. Students’ attention can be constantly drawn to their own relationship with their environment and the significance of choices and decisions that they make in their own lives. It is intended that students develop a sound understanding of the interrelationships between environmental systems and societies, rather than a purely journalistic appreciation of environmental issues. The teaching approach therefore needs to be conducive to students evaluating the scientific, ethical and socio-political aspects of issues.
The international dimension
Environmental issues are both local and global in their extent. This course reflects the international element throughout but, where it may be drawn particularly to the attention of the students, this is highlighted alongside some assessment statements (Int).
We all live on one planet Earth, yet use much more than one planet Earth’s worth of resources. This is obviously not sustainable and this course attempts to discuss the issues surrounding resource use at various scales—from that of the individual (for example, attitudes to recycling) to that of the global community (aims 1, 2, 6 and 8 in particular).
Internationally, both governmental and non-governmental environmental organizations are considered in the course, from the United Nations Environment Programme (UNEP) to Greenpeace and the World Wide Fund for Nature (WWF).
Environmental scientists work internationally at all levels. In this course, students may share data collected with those in other IB Diploma Programme schools on other continents just as professional scientists pool their data. Students taking this course should thus become more aware of the diversity of cultural perspectives on the environment (aim 4) and appreciate that environmental issues may be controversial as they cross geographical and cultural boundaries (aim 7).

Assessment statements
Assessment statements, which are numbered, are expressed in terms of the outcomes that are expected of students at the end of the course (for example, “2.1.1 Distinguish between biotic and abiotic (physical) components of an ecosystem”). These are intended to prescribe to examiners what can be assessed by means of the written examinations. Each one is classified as objective 1, 2 or 3 according to the command terms used (see the “Glossary of command terms” section). The objective levels are relevant for the examinations and for balance within the syllabus, while the command terms indicate the depth of treatment required for a given assessment statement.

Top tips for Exam Success!
1. Practice, practice, practice, practice, practice, practice, practice, practice, practice,
2. Learn the Command Terms!
3. Revise well ahead of time
4. Check that you are happy with all the relevant sections in the syllabus. Can you give them J
5. Start your revision with the bits you DON’T like – then you can fill in the gaps before you start going over all the stuff you already know
6. Practice some more. Ask for more practice. And then do more practice. There are only so many questions the examiners can think of, so if you master them all, you can’t go wrong!
In The Exam
1. Read the paper through once completely before you even write anything down. It will help you judge the time.
2. Read every question carefully. Avoid silly mistakes
3. Highlight the Command Terms as you go through – it will help you focus on what the examiner wants to read
4. If the question is worth one mark, write one point. If it is worth five marks, they are looking for five bits of information. If possible write six or seven relevant points. Pay attention to the marks!
5. Of course, CHECK YOUR ANSWERS.
Strategies for Data-based Questions:
Ø Questions will ask you to read the data or draw conclusions from it.
Ø Check the marks for each question. The examiner will compare your answer to the accepted answer. You can write as much as you like as long as you don’t contradict yourself. If you write something wrong, no marks are deducted, BUT if you contradict yourself, you will receive no marks.
Ø You are expected to use the data within the question
Ø Become familiar with units - kJm-2yr-1
Ø If asked to calculate , you must show working
Ø Compare – clearly relate BOTH similarities and differences between 2 sets of data, usually involves numeric data and MUST include units. Do a full comparison and be sure to state whether any difference is an increase or decrease.
Ø Use a RULER to draw lines on graph to help you increase your chance of being within the tolerance allowed by mark scheme.
Strategy for Open-ended Questions
Ø You MUST be familiar with Command terms. Discuss, explain, describe and outline – give the facts, not an opinion or theory.
Ø Explain – relate mechanism of how something works, usually requires a long response. There are no penalties for writing too much. Check the marks.
Ø Discuss – make sure you present at least two alternate views. Eg. Imagine there is a discussion question on conserving the rainforest. You must give opposing views why the rain forest should and should not be conserved.
Ø List – you must give the EXACT number of things asked. Eg. If asked to list 3 factors which affect distribution of plant species – only list 3. If you list 4, the fourth answer will not be marked.
TIPS TO REMEMBER
1. The examiner does not know you. You must communicate fully what you know and not expect the examiner to “fill in the blanks” for information that you do not relate.
2. State the obvious in your answers. Many of the items in the mark scheme will be information that is very basic in relation to the question.
3. Do not use abbreviations that may be unfamiliar to someone else. Be clear and concise with your choice of words
4. If you have handwriting which is very small or not clear, PRINT your response. If the examiner cannot read your writing, you will get NO MARKS
INTERNAL ASSESSMENT
General information
For internal assessment, a number of assessment criteria have been identified. Each assessment criterion has level descriptors describing specific levels of achievement together with an appropriate range of marks.
