You are teaching in class with a focus not only on the subject area, but also on SUPPORTING TRANSVERSAL SKILLS. You want to understand and assess students' performances in a holistic manner, considering the learning process as well as the learning product.
It is difficult to get an insight into a student's learning process. The learning process can be only analyzed retrospectively, provided enough documentation is given.
Therefore, use the EPORTFOLIO-approach in class, a specific form of a content-management-system (CMS), which allows students to collect and present their artifacts. Within the portfolio, the collected learning products can be linked to the learning process. This way, a basis for documentation, reflexion and presentation of learning is established. The teacher, who is an "outsider" to the students' learning process, can gain a holistic understanding of the students learning pathway and is able to assess both, the process and the product of learning.
Students document the learning process through an online learning journal. Furthermore, they collect learning products. This evidences of learning are the basis for ASSESSMENT, SELF-ASSESSMENT, FEEDBACK, RECOGNIZING and APPRECIATING.
In a Greek school, a teacher used the EPORTFOLIO-approach in English Class. Students documented, discussed and reflected on Mahara, an open-source EPORTFOLIO-plaftorm. Get a better idea of how the EPORTFOLIO helps to document individual learning pathways and watch this video: A Greek student explaining how she used her EPORTFOLIO and other features of the Mahara-platform to document her learnings about Safety on the internet in English Class.
