Abstract
Learning the first steps in programming is one of the key
activities in the area of educational computing. Although a lot
of different programming languages and environments have
arisen in the past years, many of the modern ones being
completely visual, the LOGO programming language is still
considered one of the most elaborate and most widely used
for learning the first steps in programming for the children in
elementary education. In this paper we present an educational
programming environment based on the LOGO programming
language implemented entirely as a web application. Using
only a web browser the users can access the web application
where they can learn the LOGO programming language by
writing LOGO programs, executing them and instantly
observing the output of the execution in the browser. The
code editor and the interpretation of the LOGO code are
implemented in JavaScript and the output is drawn on
HTML5 canvas element so that complete processing is
performed client side. The code editor is aware of the LOGO
syntax and provides syntax highlighting, auto completion and
programming help in the form of tooltips. The web page
promotes the “learning by doing” approach to LOGO
learning. It contains explanations of the basic LOGO
instructions and set of predefined tasks for user exercise. The
tasks are in the form of target drawing and the user is
requested to write the LOGO program that will produce the
requested drawing. The system also keeps a record of the user
activities and his progress.
