The paper contains results of a content analysis performed on the papers published in the proceedings from the previous fourteen years of the conference Project-based Education in Chemistry (1st-7th), Project-based Education in Chemistry and Related Fields (8th and 9th) and Project-based Education in Science Education (10th-14th). More than 200 papers were analysed.
As far as the topics are concerned, the traditional focus on practical examples of projects have been complemented with topics about inquiry-based education and also theoretical papers in the last several years. The trends suggest not only growing numbers of participants, but also orientation to broader spectrum of topics which are represented by student activating strategies.
The most frequent topic concerns salt followed by topics concerning food, water and environment.
