Industry 4.0 - Smart Companies and Smart Schools, Partnership for Educational Europe project was an intensive international six-sided cooperation of ICT teachers, their students (partners from the Czech Republic - MSŠ - applicant organization; Norway - AVGS and Austria - BHAK-HBLW - partner organizations), and also ICT experts (ATS, Dynatec, and Oberaigner Powertrain GmbH - partner organizations) in the field of Industry 4.0. The cooperation was divided into Data Collection and Reporting, basics of Manufacturing Execution Systems and Manufacturing Operations Management, Smart Products, Mechanical and Product Design, and Marketing 4.0. All these fields were supervised by successful international ICT companies, which practically solve these areas in their commercial activities. The project's main objective was to improve pupils' ICT skills concerning ICT companies' requirements – their potential future employers. Also, the teachers of ICT subjects (and even their students) gained the opportunity to enhance their skills and VET competencies and compare the Czech, Austrian, and Norwegian school practice differences. The results and outputs of the project are the following: 1) Innovation, modernization, improvement of the teaching of vocational subjects that relate to the Industry 4.0 (mainly ICT subjects - database systems, programming, robotics, 3D printing, etc., as well as economics, vocational English). We got to know using PLC = production line control mechanism, samples of data collection and production line simulator, and work with the database – reporting. Moreover, we got knowledge and skills in SolidWorks software as an advanced tool for the Mechanical Design and production of a modeled unit on a CNC machine.2) The comparative study that maps the strengths and weaknesses in the relationship between secondary school pupils' professional training and effectiveness of professional involvement in the Industry 4.0. 3) We processed and tested the two-phase graduation questionnaire. We asked the young employees of ICT companies operating in Industry 4.0 how the VET schools prepared them to exercise their profession, what precisely in their work can be used, and what they missed during the studies. 4) Amendment of curricula among all the participating schools is one of the most crucial project results. 5) We managed to reach out to various local communities, especially young people, experts, and educational policymakers, through dissemination activities. The teachers and pupils joint in the project presented their experience, skills, and abilities in the areas of Industry 4.0 and the outputs of the project in the #ErasmusDays campaign. We received the award for the best-organized 2018 event in the Czech Republic. For this, we made big information panels at the square of the town of Nový Jičín. We prepared project maps, interactive presentations of the project results achieved so far, and competitions for primary school pupils The project was based on 2 training activities - joint student workshops in Data Collection and Reporting, Manufacturing Execution Systems, Smart Products, Mechanical, and Product Design. Due to the closure of borders and schools, and the need for social isolation (COVID-19 measurements), we had to cancel the Marketing 4.0 workshop in AT. Important preparative and evaluation moments were 4 transnational project meetings, where the teachers of ICT and other relevant VET subjects, project management, and Industry 4.0 professionals were present. Teachers were first trained by expert staff from the partner companies. Under the supervision of companies' professionals, these teachers from the 3 partner schools created work tasks and assignments, which they solved together with their students and shared the ongoing results and work (video conference, shared documents, social networks, electronic communicators). An essential point of verification of successful solution of tasks and the quality of teaching lessons at school was the organization of workshops, some of which occurred in the partner companies. In cooperation with their teachers and international remote collaboration, pupils solved the work tasks arisen from the assignment created during transnational project meetings. According to their project role, experts from companies trained VET teachers in specific areas of Industry 4.0. And subsequently, lead the program during training activities. They continuously monitored the success rate of solving tasks. Project activities will bring long-term results, even outside organizations directly involved in strategic partnerships. Sustainability of the project is guaranteed by joining members of the local community, local and regional politicians, VET teachers, coordinators of EU projects, and education system from regional authorities, press, and media representatives into the dissemination plan.
