2. CuRRicula Each partner country prepared a document outlining all the topics covered in the curricula of the three subjects covered by the OTA project: Mathematics, Chemistry and Physics. The countries were asked to describe the curricula and track some data specifically: - Content - Content subset - Operational goals - General competences - Interdisciplinary integration The aim was to find common topics within the four different curricula between the countries and on this basis to build the survey and the next project results. Although the four curricula were somewhat different, the consortium managed to create a list of common topics and sub-topics. These were then used and incorporated into the second part of the survey, the aim of which was to investigate which topics were considered by teachers to be the most difficult to teach online and which topics they perceived most difficult for their students during online learning. 4
