In IB Physics First Assessment 2016, electric fields is a subtopic of Topic 5, electricity and magnetism. This subtopic has the following understandings associated with it.
- Charge
- Electric field
- Coulomb’s law
- Electric current
- Direct current (dc)
- Potential difference
In this part of the analysis, I am particularly interested in “What is the frequency distribution of the questions concerning electric fields understandings?”
Frequency distribution of questions by electric fields understandings for HL
Between 1999-2023
For the entire dataset for HL, almost half of the questions assessed understanding the electric field. Electric charge, Coulomb’s law, and electric current accounted for the remaining half of the questions. Potential difference was rarely assessed. Direct current was not assessed at all.
Figure 1
Between 2016-2023
Between these years, the emphasis on the electric field remained. Electric current also became dominant. Potential difference was again rarely assessed. Again, direct current was not assessed at all.
Figure 2
Frequency distribution of questions by electric fields understandings for SL
Between 1999-2023
For the entire SL dataset, the questions are more evenly distributed among the understandings. Only direct current was barely assessed.
Figure 3
Between 2016-2023
Between these years, the understanding of charge was not assessed. The emphasis on electric field and electric current increased.
