Considering that digital assessment of mathematics is becoming widespread and comes both with affordances and constraints, we wanted to successfully achieve the following objectives for the participants of the project: (a) be informed about the features and functions of innovative digital tools that serve the assessment of students' mathematical knowledge, (b) learn how to integrate in their daily mathematics lessons digital tools that serve the principles of formative and summative assessment, (c) acquire digital skills that are required for creating and disseminating digital tasks that assess mathematical knowledge in a valid way, (d) learn how to interpret the automated scoring and other information that digital assessments provide, (e) learn how to use the results of digital assessments to offer constructive feedback to their students and improve their instruction, (e) link formative and summative assessment with the teaching and learning to support students' motivation and interest for the subject of Mathematics, (f) improve their language and communication skills, (g) become aware of other educational systems and best practices across Europe.
We applied for this project to promote the professional development of teachers, school leaders, and other school staff in aspects concerning the use of new technologies and innovative teaching, learning, and assessment methods. We considered that this Erasmus + project could play a key role in supporting the participants to (a) engage with the notion of digital transformation of education, (b) improve their digital skills and competences, (c) use, create and disseminate digital education content that complements and improves the quality of classroom activities. Mathematics was selected as the focal school subject, considering the significance paid by all school curricula across Europe on the development of mathematical reasoning and the high percentage of the teaching time devoted to this subject on a weekly basis. In this context, this project encouraged mobility activities that provided the participants with rich opportunities for training in new trends in the teaching, learning, and assessment of mathematics that are fit to the digital age. Moreover, the project aimed to enhancing the participants' knowledge about shared European heritage and practices that promote school development.
