The European Language Portfolio has been at the core of the CEFR. The ELP is connected to learner autonomy, reflective learning, formative assessment and many more areas. The implementation had its ups and downs. The Round Table Talk invites those in the field of foreign language teaching who are interested in the use of a portfolio in language teaching and want to discuss and share implementations, case studies, experiences with the ELP, language portfolio, learning portfolio, journal etc. The ELP is connected to learner autonomy, reflective learning, formative assessment and many more areas. At recent conferences, since the launch of the CEFR/CV there is a steady increase on papers on language portfolio. This Round Table Talks wants to initiate a synergetic working group. You are welcome to take part and share and listen and discuss. CEFR & Language Portfolio SIG wants to emphasize on the CEFR and CEFR/CV as well on the second part of its name, the Language Portfolio.
