This video from the jct.ie site deals with the reasons for creating a language portfolio and may give you some ideas in your approach to it.
Here is the MFL Assessment Guidelines document (2017 edition – I don’t know if there’s an updated one). This document includes information about the Classroom-Based Assessments and important dates etc.
And yes, this is the task about which you will have learned on your Cluster Day, which the students complete in English. You can see here that it says in black and white that it will be worth 10% of the marks used to determine the final grade. This came up for discussion at the PDST MFL Alive day, where many teachers were left wondering whether in fact it was worth 10% or not, but it seems that it is.
And finally, this is a screenshot of information about the exam. Again at the PDST MFL Alive day, there were questions about the paper and what shape it might take, but the JCT MFL facilitators are not yet privy to this information, which will come from the SEC.
There are a couple of examples of student work on the curriculumonline.ie website, but you must be logged in to view them. Apparently new work will be added, but it has not yet been since last year.
This section entitled Planning, Teaching and Assessment, I found, quite frankly, confusing. They talk about “themes,” which we were explicitly told in our Cluster Day to avoid when planning. It appears to be an entirely separate document which looks extremely like the old syllabi but which individual schools or teachers might be expected to work up? I know that in our school we’re having enough time trying to get our heads around the units of learning, so I’d say we will be waiting for further information and guidance on this before embarking on it. In the meantime, if you do know more about it, please let me know and I’ll be happy to update this.
