the core of the essay. In some cases, footnotes were also included but no quotation marks were inserted in
the text where whole sentences and even paragraphs were directly taken from textbooks, magazines or
Criterion H Holistic judgment
Man y supervisors did not offer any comments on the cover sheet, making it more difficult for the
examiners to assess the originality of the essays or the personal input of the candidates. Routine
investigations or general surveys could not score well. General ly, inventiveness and flair were rare.
Experimental techniques in laboratory -based essays were not always challenged. Top marks were few.
Criterion J Principles of physics
Overall, the knowledge of the candidates was acceptable. Very few students managed to demonstrate
excellent knowledge. Some failed to communicate their knowledge or chose trivial topics. Candidates
who chose a “straightforward” topic (outside the syllabus) and performed their own experimental
investigation were able to score high marks. Some survey essays contained little or no physics. In the
weaker essays, there was a tendency to give what are essentially qualitative descriptions of physical
The study of a topic beyond the level of understanding expected in the theory examinati ons should
generally be discouraged, as it is here that weaknesses become apparent! Examiners are not necessarily
impressed by complicated equations extracted from advanced textb ooks or web pages when it is evident
that the candidat e is actually overwhelme d by the top ic! Some models associated with difficult topics
were actually flawed. Some candidates explored concepts beyond the IB physics syllabus and
successfully took advantage of external resources to the school.
Criterion K Use of methods or sources appropriate to physics
In a good number of laboratory essays, the methods chosen were appropriate but, unfortunately, they were
executed routinely with little flair or personal input. Very few candidates we...
