The world is changing

• Population growth

• Resource consumption

• Globalisation and international trade

• Climate change

• Ocean acidification

• Pollution

• Rapid decline of biodiversity

• Habitat loss and fragmentation

• Invasive pests

Biology is changing

• Collaborative

• Multi-disciplinary

• New technology

• Next generation DNA sequencing

• Massive amounts of data

• New analytical methods

• Reproductive technologies

• Genetic manipulation

• Synthetic biology

Biology is changing

Keys to success in modern biology

• Shift from specific knowledge to generic skills

• Shift from specialisation to multi-disciplinary collaboration and

synthesis of ideas

• Shift from particular technological approaches to strategies for

learning and adapting new techniques

• Ability to integrate knowledge from different areas

Research skills, philosophy of science, how to make and record observations, ask questions, construct testable hypotheses, design experiments, analyse results, make inferences, communicate findings, etc.

Information literacy, finding and assessing the quality of information, critical thinking, critical literacy

Keys to success in modern biology

Quantitative thinking, data management, computing, maths, bioinformatics, statistics

Visualisation, creative presentation of data, dissemination of research outcomes, public outreach

Collaboration, working as part of a team, understanding, empathy, effective communication

• Cultural sensitivity, cross-cultural communication, languages

• Entrepreneurship, commercialisation, business knowledge, economics, policy

• Ethics, moral philosophy, social science

Keys to success in modern biology

A high-level of academic achievement is not necessarily as important as…

• Curiosity

• Enthusiasm

• Creativity

• Logical reasoning

• Practical ability

• Persistence

The New Zealand curriculum

• Nature of science strand

• Integration of biology with other strands (e.g. maths and statistics, technology, social science)

• NCEA achievement standards (biology matrix)…

2.1 – Carry out a practical investigation in a biological context, with supervision

2.2 – Analyse the biological validity of information presented to the public

3.1 - Carry out a practical investigation in a biological context, with guidance

3.2 – Integrate biological knowledge to develop an informed response to a socio-scientific issue

Careers in biology

Biology + computing = bioinformatics

Biology + social sciences = management, policy making, politics, communication

Biology + commerce = product development, commercialisation

Biology + languages = international collaboration, economic development

Biology + arts = data visualisation, landscape ecology, biomimetics
