7 CONCLUSIONS
Digital technologies have allowed the realization of
LDL during the first Italian lockdown, resulting in a
massive use of such technologies for almost the entire
school population over three months. On the one hand,
the possibility of collecting and sharing information
in an efficient way is a known effect of digital
technologies. On the other hand, during the first
lockdown in our country, the widespread use of
digital technologies has become constitutive of any
didactical practices, generating a huge amount of data
at the disposal of students and teachers. Despite the
undeniable difficulties encountered, this period will
result in a wealth of experience on which teachers and
students can decide to work, making the most of it.
Within this work, we tried to shape this wealth of
experience using the construct of FA, that guides our
eye as researcher in mathematics education and limits
the multiple phenomena we observed during LDL.
More precisely, we structured a theoretical tool based
on FA theoretical framework in order to link FA
indicators to spontaneous teachers’ and students’
actions and behaviours we observed. We found that
the listed above 9 out of 72 indicators can be ensured
simply by being in a digital-technology based
environment and they are responsible for the huge
amount of didactical data that can be managed.
Nevertheless, not every teacher takes advantage of
this possibility in the same way, some of them feel
overwhelmed by all the received information. One
way to manage the increased workload could be the
intentional use of FA construct in its entirety, and FA
practices. For example, the use of S4 and S5 would
allow the teacher to redistribute workload between
her and the students. We could say that is the
management of the effect of the 9 indicators that led
to the emerging of practices that could be associated
with the FA construct. We have evidence of at least
one teacher whose spontaneous didactical agency can
be described using more than half of the FA indicators,
widespread along with the five FA strategies and we
believe that other teachers can take advantage from
this work. Indeed, every teacher that implemented
asynchronous practices, or that recorded her
synchronous lessons during LDL, has at her disposal
a huge amount of data of the same kind we analysed
about her didactical practices, and can eventually
analyse them herself. Moreover, professional
development on FA from now on could work not only
on shared experiences and individual practices, but
also in the direction of a decreasing of the workload
thanks to intentional use of FA from the teachers’ side.
As we show in the analysis of classroom observation,
some peculiarities of such environment impact the
deepest feature of human interaction, for instance, we
can refer to the storage and access to data introduced
in section 6. Thus, another direction seems to be of
high relevance within the context of digital-
technology based environment: the study of the
specific instantiations of known theoretical constructs
of mathematics education.
