Help with the Internal assessment (IA)

The internal assessment aspect of the course involves three principle elements:

1) The attainment of laboratory skills in the completion of either 40 or 60 hours of time involved in a practical scheme of work. This is a requirement of the course, although no grades will be submitted.

2) The Group 4 project, which will involve collaboration with other group 4 subjects (the sciences and mathematics).

3) The IA Individual Investigation, which is worth 20% of the over all grade.

The IA Individual investigation dominates the landscape of the new IB criteria, and a comprehensive guide can be downloaded from the link below.

What should it look like?

Three examples of successful student Biology IAs (with moderators comments). They are contrasting types:

  1.  experimentation
  2. manipulation of secondary data,
  3.  use of a simulation

How do you judge the quality of an IA? An IA is graded using the following rubric:

A reminder…the Conclusion and Evaluation section is probably the most important. See this guide to doing a good job of the conclusion and evaluation section
