 2024 Key Changes
IB Diploma ESS

  • Main Course Content

    Both SL and HL students gain an understanding of the complexities of environmental issues, solutions, and management during the ESS course. Common features of the course at both SL and HL include: 
     
    1. A concept-based syllabus that promotes holistic thinking about strategies to address environmental issues (discussed below) 

    2. A foundation topic (Topic 1) that introduces and explores the key concepts 

    3. A common internal assessment (IA) 

    4. The collaborative sciences project, where students work with other students across all the IB Sciences to explore a real-world problem. 

    The SL course provides a fundamental understanding of ESS and experience of the associated skills. The HL course includes HL-only understandings, underpinned by an exploration of ethical, legal and economic issues relating to the environment (the ‘HL lenses’). The additional content within topics 2-8, along with the HL lenses, allow HL students to analyse problems at greater breadth and depth, with additional potential for higher-level evaluation. For HL students, the HL extension lenses apply across both SL and HL content. Suggested connections of the HL lenses to topics 1 to 8 are made throughout the course.

  • Key Concepts

    ESS has always been a concept-based curriculum, but in the new Guide this has been streamlined to three essential key concepts: perspectives, systems and sustainability. The first topic, Foundation, explores these three concepts so that students can apply them throughout the course. There is a clear intention in the 2024 Guide for these foundation topics to be taught first. 

    The holistic understanding required by the course is supported in the new syllabus by the interplay between the ESS concepts, skills and content. These three components act like threads, weaving throughout the course and providing a clear framework for students. This networked learning enables students to connect ideas and develop a deep-seated understanding of the issues covered by the course. ‘Big questions’, which helped students make connections between different parts of the course in its previous iteration, are no-longer used in the 2024 Guide, but strong links between all aspects of the course are evident throughout.

  • Guiding Questions

    A new innovation in the new Guide is the ‘guiding questions’, which are shown at the beginning of each subtopic. The guiding questions frame and direct inquiry for the learning within the subtopic. To help students and teachers navigate the course, each subtopic is now divided into numbered understandings, which are, in turn, divided into a content statement and notes. 

    This allows connections to be easily made between different parts of the course. Some understandings also include reference to the application of skills, discussed below. Most subtopics also have additional content which is for HL students only (Topics 2-8). The content statement indicates the content to be taught, and the notes provides guidance on the scope and requirements of the content statement, e.g., the level of detail needed. Each understanding has numbered links to other sections of the Guide, to allow students to make connections between all parts of the course.

  • Skills Applications

    There are many skills needed to study the ESS course successfully. These skills include experimental techniques, technology, mathematical and inquiry skills, and the constructing and interpretation of systems diagrams. Skills are at the heart of the ESS syllabus and emphasise the practical nature of the subject. By actively applying these skills in context, students are more likely to develop and retain an understanding of how these skills can be realised. In previous iterations of the ESS course, these skills were implicit, and it was left to teachers when and how to deliver them.

    In the new Guide, ‘application of skills’ are listed in many understandings, providing both students and teachers with a clear context in which to explore and develop these key skills. Skills are therefore made explicit. There is a new section in the Guide, ‘Skills in the study of environmental systems and societies’, where skills are categorized as ‘tools’ (including experimental techniques, technology, mathematical skills, and systems and models) and ‘inquiry’, which lay out investigative skills that can be applied in the Internal Assessment.

  • Student Engagement & Altruism

    The ESS course is not just an opportunity to study an innovative and demanding subject, but one which also asks students to engage and act on the issues they are studying. A new initiative in the 2024 Guide are engagement activities, with potential engagement opportunities provided at the end of each subtopic. Although these are not examined, some of these may be a foundation for CAS activities within DP, whereas others may be a starting point for individual or whole-school action. These engagement opportunities could also be labelled as chances to ‘take action’, which helps them to develop a sense of agency about the environmental issues they study. Rather than simply becoming frustrated by environmental issues, students have the opportunity to do something about them.
