 The following list includes papers that discuss the initial version of TRAKLA [56], its web-based front-end WWW-TRAKLA [48], and finally the latest version TRAKLA2 [32]. The main contribution is the concept of visual algorithm simulation [30] and the corresponding exercises utilized in TRAKLA2. We have conducted a number of evaluation studies [18,31,45,41] that have revealed many important aspects of these exercises as well as web based learning environments in general. For example, the intervention study [41] shows that there is no difference in learning results among students practising on the web with algorithm simulation exercises and students working in closed labs if the assignments are the same.
