  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.",
