  1. IBO Biology General information

  2. SL group 4 curriculum model Theory Core: 180 hours 2 Options: 30 hours (Neurobiology and Behaviour, Microbesand Biotechnology) Practical work Investigations: 30 hours Group 4 project: 10 hours

  3. HL group 4 curriculum model Theory Core: 80 hours Additional higher level: 55 hours 2 Options: 45 hours Practical work Investigations: 50 hours Group 4 project: 10 hours

  4. SL Assessment specifications

  5. HL Assessment specifications

  6. Paper 1 • Made up of multiple-choice questions that test knowledge of the core • The questions are designed to be short, one or two-stage problems • No marks are deducted for incorect responses • Calculators are not permitted, but students are expected to carry out simple calculations

  7. Paper 2 • Tests knowledge of the core (for student SL) and the core and AHL for students HL • A calculator is required for this paper • Paper is divided into 2 sections: • Section A, there is a data-based question that requires students to analyse a given set of data • Section B, students SL are required to answer 1 question from a choice of 3, and students at HL are required to answer 2 questions from a choice of 4. These extended-response questions may involve writing a number of paragraphs, solving a problem, or carryimg out a piece of analysis or evaluation

  8. Paper 3 • Tests knowledge of the options • Students at SL are required to answer several short-answer questions in each of the 2 options • Students at HL are required to answer several short-answer questions and extended-response question in each of the 2 options • A calculator is required for this paper

  9. Internal assessment criteria There are 5 assessmentscriteria that are used to assess the work of both SL and HL students: • Design (D) • Data collection and processing (D&P) • Conclusion and evaluation (C&E) • Manipulative skills (MS) • Personal skills (PS)

  10. The first three criteria are each assessed twice • Manipulative skills is assessed summatively over the whole course and the assessment should be based on a wide range of manipulative skills • Personal skills is assessed once only and this will be during the group 4 project

  11. The maximum mark for each criterion is 6 Design: 2 x 6 =12 Data collection and processing: 2 x 6=12 Conclusion and evaluation: 2 x 6 =12 Manipulative skills: 1 x 6 =6 Personals skills: 1 x 6 =6 Total: 48 This is scaled at IBCA to give a total out of 24 %

  12. Syllabus overview • Statistical analysis • Cells • Cell theory • Prokaryotic cells • Eukaryotic cells • Membranes • Cell division • Meiosis (+AHL) 3. The chemistry of life • Chemical elements and water • Carbohydrates, lipids and proteins (+AHL)

  13. 4. Enzymes, Cell respiration, Photosynthesis (+AHL) 5. Genetics • DNA structure (+AHL) • DNA replication (+AHL) • Transcription and translation (+AHL) • Chromosomes, genes, alleles and mutations • Theoretical genetics (+AHL) • Genetic engineering and biotechnology 6. Digestion + Option: Human nutrition and health (just for SL) and Digestion, absorption of digested food, functions of the liver (just for HL) 7. Gas exchange + Option: Gas exchange (just for HL)

  14. 8.The transport system + Option: The transport system (just for HL) 9. Defence against infectious disease 10. Nerves, hormones and homeostasis + Option: Hormonal control (just for HL) 11. Reproduction

  15. AHL (just for VIP-s) • Proteins • Meiosis • DNA structure • DNA replication • Transcription • Translation • Dihybrid crosses and gene linkage • Polygenic inheritance • Enzymes • Cell respiration • Photosynthesis • Plant structure and growth • Transport in angiospermophytes • Reproduction in angiospermophytes

  16. Defence against infectious disease • Muscles and movement • The kidney • Reproduction
