  The tutor-web drilling system is designed for learning so there are typically
no limits on the number of attempts at improving performance. This system is
used at multiple schools and universities in Iceland and Kenya, mostly for
mathematics and statistics. Students earn SmileyCoin, a cryptocurrency, while
studying. In Iceland the system has typically been used by students who use
their own devices to solve homework assignments during the semester, accessing
the Internet-based tutor-web at http://tutor-web.net. These students typically
take final exams on paper at the end of the semester. In Kenya the system is a
part of a plan to enhance mathematics education using educational technology,
organised by the Smiley Charity with the African Maths Initiative. This has
been done by donating servers running the tutor-web to schools and tablets to
students. Typically these schools do not have Internet access so the
cryptocurrency can not be used. Innovative redesign was needed during COVID-19
in spring, 2020, since universities in Iceland were not able to host in-house
finals and schools in Kenya were closed so tablets could not be donated
directly to students. Remote finals were held in Iceland but the implementation
was largely in the hands of the instructors. In Kenya, community libraries
remained open and became a place for students to come in to study. Innovations
included using the tutor-web as a remote drilling system in place of final
exams in a large undergraduate course in statistics and donating tablets to
libraries in Kenya. These libraries all have access to the Internet and the
students have therefore been given the option to purchase the tablet using
their SmileyCoin. This paper describes these implementations and how this
unintended experiment will likely affect the future development and use of the
tutor-web in both countries.
