"Creating a modern and efficient STEM education system is a priority in all European countries as education faces a digital challenge: need to adapt traditional teaching methods and offer a mix of face-to-face and online learning possibilities. The pandemic situation has cleraly highlighted the relevance of this situation So, in this context, ITEMS main objective is to design and promote innovative methods, pedagogies, learning materials integrating e-assessment tools and assignments activities for STEM teaching, at Higher Education and high school level as well. Good digital learning materials and exercises, as well as e-assessments for STEM subjects require interactive graphic possibilities, randomized questions, multi-language options, and adaptive automated responses. In ITEMS we brought these technologies together, by using the Learning Management system Moodle, the question types STACK and Formulas, as well as the JavaScript graphics library JSXGraph.Project partnership is composed of five-country multi-sectorial consortium composed of a research institute (Center for Mobile Learning, Bayreuth U), three universities: Aalto U(FI), Maribor U(SL) and Jihoceska U (CZ), a high school (IES Mediterrània, SP), an edutech company (BNedu, SP) and a regional education authority (Conselleria Educación de Comunitat Valenciana, SP) working in a collaborative European perspective. This consortium has achieved the following results:1. ITEMS has gone further in the research and development of JSXGraph software. In close collaboration among all partners important new features have implemented and the interplay with Moodle questions types STACK and Formulas has been much improved and made easier.A relevant event has been the 1. International Conference (https://jsxgraph.org/conf/program/) held online in October 2020.On the one hand, ITEMS has facilitated extensive use of JSXGraph by educators through the creation of an interactive HANDBOOK which has been publicized through several communications (e.g. https://itemspro.eu/2019/11/27/items-project-at-moodlemootglobal/) and through the MOOC: JSXGraph programming. Big interest in learning advanced JSXGraph features has been expressed during the conference. As a result a free monthly webinar on “Advanced JSXGraph programming"" with a worldwide audience has been established (https://jsxgraph.org/wp/docs).On the other hand, all of these developments had a positive influence on the creation of more effective and engaging activities for students by the project partners. By using JavaScript technology it is guaranteed that these ITEMS modules will run in every platform and any browser including mobile devices.2. ITEMS partnership has developed 3 STEM-Moodle courses: one at University level and two at High School level. All of them integrate JavaScript based interactive animations in Moodle quizzes mainly using JSXGraph, integrated in Formulas and STACK questions. This allows students to perform function plotting, charting and visualization aimed to enhance conceptual understanding in STEM subjects. During the development phase, materials were presented at several professional development activities and finally discussed among educators community through two MOOCs. 3. ITEMS project results have been disseminated through more than 10 presentation events at conferences and teacher training activities and through social media (project blog, youtube, ...). In addition, three professional development courses and workshops have been performed, at national level, and four at European level involving in total more than 100 teachers.3. Through the ITEMS Academy, modules have been piloted by partners and collaborator schools several times in different educational contexts during the project lifespan, involving more than 900 students. Project impact has increased by means of using innovative LTI tools which allow schools easy access to ITEMS modules. Project partners have contributed by mentoring teachers in using project materials while they are teaching their own students. As a result of this experience, schools have provided feedback that have contributed to the improvement of materials. Educational researchers and software developers now could use project results as examples of evidence-based guidance on effective uses of technology for improvement in STEM achievement.Finally, as long term benefit, ITEMS project server will offer permanent access to the materials as examples of good practice and to facilitate networking between the STEM teacher community.
