abstract = "A problem with teaching Computer Science to first-year
students in a South African context is that many
students come from disadvantaged backgrounds and have
not been exposed to computer technology. To address
this issue, a new curriculum has been adopted for
first-year students, the first topic of which covers
the design and specification of algorithms. One of the
problems encountered in this course is that if the
students cannot execute their algorithms they do not
know whether the algorithms are correct. One approach
to this problem is to require that students be familiar
with a programming language. This paper investigates an
alternative way of executing algorithms, the ALEX
system, and discusses how the system can be used to
assist in the teaching of algorithms. ALEX allows
students to specify algorithms in an English-like
manner and translates these algorithms into an
equivalent executable high-level language code, which
is then executed. Based on the evaluation of individual
students, the use of ALEX is beneficial. However,
further experimentation has to occur before the
effectiveness of using ALEX can be properly assessed.",
