Good evening fellow classmates,
I understand the parents' concern. It is possible for someone could piece together enough information from the portfolio to identify the student. Is it possible for the e-portfolios to be placed on an intranet? Is it possible to encrypt or password protect the e-portfolios?
What about using a password-protected Google site? Our one that is only shared with key players (student, parents, admin, current teacher)?
What blogging system are you using? Kidblog has many different security features that help to prevent unwanted people from veiwing your students portfolios. I have not had any issues with them.
It is frustrating, but as someone else pointed out, it is often possible to piece together enough information to identify someone without names and locations. Remember that the parents may have a person reason that you do not understand. I once worked with a situation where parents did not want their children's pictures posted because the children were adopted and they did not want to risk natural parents seeing and identifying the children. In this particular case, the adoptive parents were quite well known and quite wealthy and the child was adopted locally in a blind adoption.
And consider that divorced parents often have custody concerns.
This doesn't help your particular question, but perhaps my age sheds a different light on the situation.
We are also a PYP school and just moving to using eportfolios, rather than paper only. We are using Evernote. It's quick and easy to get the items (digital or 'digitialized') into the portfolio and then a link is shared only with the parents. They see only their own child's portfolio. We have also invested in a 'Business' account for the school, which allows for sharing amongst the teachers in a private space, as well as more storage space.
Perhaps you could investigate the system which you are using to post the e-folios more closely, so that you can understand the encryption that they use, the security they have put in place to prevent general access, etc. Some questions regarding whether or not e-folio work was isolated from the general traffic of the internet would probably also help allay their fears.
I previously worked for a school district which required its students to post their work to an e-folio site. Each student had a login, and each teacher had a login, as did administrators. As far as I know, the information was kept intra-site, and was not released onto the internet. I know access for teachers was limited only to those students which were in your homeroom. Most sites are quite well-protected, as they open themselves up to liability should harm come to a child as a result of information being leaked.
Hope that helps.
