Biology

At one end of the scale are the cell, its molecular structure and the complex metabolic reactions that take place there. At the other end of the scale, biologists investigate the interactions that regulate the functioning of entire ecosystems. There are still many discoveries to be made and it is expected that he will experience great progress in the 21st century.

Through the study of a science subject, students should be aware of the way in which scientists work and communicate with each other. Although the scientific method can take many different forms, a practical approach is emphasized. In addition, through the overarching theme of "Nature of Science", this knowledge and skills will be put into context in terms of how science and scientists operate in the 21st century, and the ethical debates and limitations of activity scientific

The sciences are taught in a practical way. Students have the opportunity to design their research, collect data, acquire manipulation techniques, analyze results, collaborate with colleagues, and evaluate and communicate their findings. They can carry out laboratory investigations or use simulations or databases. Students develop the skills necessary to work independently in their own design, but also in a group manner (including collaboration with schools in different regions) to reflect the way in which scientific research is carried out throughout the community.

Main characteristics of the curriculum and evaluation models

• Internal evaluation (individual research): 20%; External evaluation: 80%
• The practical approach to the delivery of the course is emphasized through the interdisciplinary activity of the 4 Group project and a mix of short and long term experiments and research.
• The internal evaluation represents the 20% of the final evaluation and is evaluated through a single individual investigation. This research may involve a practical approach, the use of databases, the creation of models, simulations or a combination of the above options. The work of the students is evaluated by the teacher internally and moderated by the IB externally.
• The external evaluation of Biology consists of three written tests. The 1 test contains 30 multiple-choice questions. The 2 test contains short-answer and long-answer questions on core topics. The 3 test has two sections: section A contains a data-based question and several short-answer questions about experimental work on core topics. Section B contains short answer and long answer questions for each of the four options.
