The project on which we report here originated as an outcome of a long-standing research collaboration on biocorrosion between the three partner institutes. We realised that by bringing interested staff together in an exchange project with an educational/didactic point of view, we could strengthen these ties, and contribute to common internationalisation aspirations in our three institutes: to enhance our institutional network, to enhance and modernise our teaching capacity, and to provide (for the Ukrainian partners) opportunities to develop better skills at communication in English. The objectives of the project were:1. to create international courseware on biological aspects of corrosion. 2. to look for a common teaching language. 3. to improve teacher skills among the participants.4. to provide a stronger network for the participantsThe practical aim was to provide a Train the Trainer course on biocorrosion (building on our ongoing common research interests), for 10 Ukrainian staff members (to be trained) and several members of the staff in Antwerp (all Ph D students, post-docs and tenured teaching staff). This course was organised by a coordinating team of three staff members, one from the three partner institutes, with the Antwerp side delivering the electrochemical knowledge and the teaching methodology, and the Ukrainian partners on the biological aspects. The different chapters in the course were prepared in a series of mutual visits of the coordinating team, leading to the course programme as added to the Annexes. Each chapter was then worked out using a suitable didactic model, in order to cover a wide array of practical methods (as well as some background and the opportunity to discuss the methods in class). Also, we sought an equilibrium between (interactive) lectures, seminars and group activities among the participants (including staff from Antwerp), and practical (hands-on) lab activities (e.g. on the analysis of anti-corrosive paint, and on the use of cheap Arduino-style electronics in a class setting). Cultural visits (Antwerp port, Antwerp Port HQ, Bruges and Antwerp culture) were foreseen to enable the participants to form ties with the Antwerp staff in an informal setting, and attention was given to an introduction into intercultural communication and its challenges. The chapters were tested among the coordinating team to ensure that at least on that level, everything was clearly understood. Finally, the Train the Trainer course took place in the first half of April 2019, at Antwerp Maritime Academy. The response of the participants indicates that most of the objectives (see below, par. 4) were achieved, as they reported an increase in their linguistic skills, the strength of their network and networking skills, their interest and enthusiasm for interactive teaching. Over the summer, several participants have developed ways to implement these newfound didactic competences into their own courses (Kahoot quizzes, a new style of lecturing,...), and have used their new network to come up with novel projects, irrespective of any funding so far. In the long run, we believe that the exchange in this project will not only help to modernise the didactic experience of the staff involved, but also encourage them to take part in more exchanges (and to set some up themselves).
