IB Syllabus Changes: The New IBDP Chemistry Curriculum
The realm of IB Chemistry is undergoing a transformative journey with the imminent arrival of the new curriculum, initially delayed by the global upheaval caused by the COVID-19 pandemic. Set to commence in August/September 2023, with the first exams scheduled for May 2025, this revamp promises to bring fresh perspectives and challenges to aspiring chemists.
The heart of the new program beats with a commitment to foster a conceptual understanding of chemistry that transcends traditional boundaries. Divided into two distinct strands – “Structure” and “Reactivity” – the curriculum departs from the previous listing of 11 main topics. This shift aligns with a broader educational philosophy aimed at exploring scientific knowledge claims within a real-world context, sparking students’ curiosity and interest.
Despite the absence of current options providing real-world contexts, the hope is that the incorporation of applied chemistry material into the new structure and reactivity strands will compensate. However, until the full syllabus is unveiled, the extent to which this integration has occurred remains a tantalizing mystery.
Assessments In The New IB Chemistry Syllabus
External Assessments: The restructuring isn’t confined to content alone but extends to the examination format. Moving from three papers to two, the new external assessment retains the essence of challenging students’ comprehension. Paper 1, which once solely featured multiple-choice questions, now includes data-based questions and queries on experimental work.
Using calculators and data booklets, forbidden fruit in the current Paper 1, adds a new layer of complexity. The potential inclusion of errors and uncertainties in multiple-choice questions raises intriguing possibilities, aligning with the curriculum’s focus on real-world applications.
Internal Assessment: A crucial segment, the internal assessment undergoes nuanced modifications. The introduction of four criteria – research design, data analysis, conclusion, and evaluation – underscores the multifaceted nature of this evaluation, now accounting for 20% of the final marks.
While students can collaborate in small groups for data collection, the requirement for independent report submission ensures individual understanding. The 6-12 page limit shackles have been lifted, replaced by a more generous 3000-word maximum for the report, eliminating concerns about font size intricacies.
Group 4 Project:
The collaborative project, a cornerstone of real-world applications, stands resilient in its ten-hour format. Offering a bridge between theory and practice, it continues to challenge both teachers and students, demanding a demonstration of comprehensive understanding gleaned throughout the program.

IB Syllabus Changes: The New IBDP Biology Curriculum
If you’ve been acquainted with the DP Biology curriculum between 2016 and 2023, the winds of change may have caught your attention in the new IB Biology 2023 syllabus. Aiming to foster a more profound conceptual understanding, this transformative shift not only alters the layout but also brings a fresh approach to teaching biology.
Layout & Approach Changes:
The most conspicuous change lies in the layout, meticulously designed to kindle a more conceptual grasp of biology. The guide encourages teaching approaches that weave connections between topics, enabling students to see the bigger picture within the realm of biology. The appearance and titles of topics may seem novel, but the essence of the content remains grounded, ensuring the guide is not only more useful but also more effective.
Guidance For Innovative Teaching:
Accompanying the layout alterations is an updated IB sciences experimentation guide. This guide specifically outlines the methodologies for conducting experiments in microbiology, ecology fieldwork, risk assessment, waste disposal, animal experimentation, and dissections.
The emphasis is on ethical conduct, acknowledging that certain animal experiments can be conducted ethically with adherence to specific guidelines. These changes provide teachers with a broader spectrum of resources, fostering innovative and engaging ways to teach biology.
External Assessments:
Assessment Objectives:
- The four assessment objectives persist with slight changes in wording.
- Command terms in exams remain consistent.
- A general understanding of the nature of science is expected.
Internal Assessment (The Scientific Investigation):
The individual investigation (IA) now takes on the name “The scientific investigation” but retains its weightage of 20% in the overall assessment. The collaborative dimension is heightened, allowing students to work in groups of up to three while retaining individual research questions. Key changes include:
- Word Count: A maximum of 3,000 words, with clear guidelines on what constitutes a word.
- Assessment Criteria: Research design, data analysis, conclusion, and evaluation are assessed, each with equal weighting, emphasizing concluding and evaluating skills.
- Flexibility: While the name and assessment criteria evolve, the overarching purpose remains unchanged — to nurture scientific skills through independent research.
Syllabus Content Changes:
Volume Reduction: A deliberate reduction in content, approximately 5%, compared to the 2014 guide.
Options Integration: The removal of options from the 2023 guide reduces content hours (15 SL, 25 HL). However, parts of the options are integrated into SL and HL courses, offering a more consolidated learning experience without increasing the total content.
Terminology Changes:
Individual Investigation → Scientific Investigation
Group 4 Project → Collaborative Sciences Project
In essence, the changes in the IB Biology 2023 syllabus bring a more dynamic and interconnected approach to biology education. It offers students greater flexibility, encourages collaborative learning, and ensures that the assessment criteria align with the evolving demands of scientific inquiry.
