This study presents a pilot evaluation study of LAMS performed by Greek Computing teachers. The aim of this study is twofold: to investigate the usability of LAMS as a whole context of tools as well as to evaluate a specific learning tool - entitled the Questions & Answers Cognitive Skills-Wizard (Q&A CS-Wizard) - through the lens of the aforementioned teachers. This tool is integrated within LAMS for the improvement of the creation of questions to encourage the development of students' cognitive skills. Seventeen Computing teachers participated in a learning design experiment for the design of lesson plans using LAMS. The analysis of the data shows that those teachers' lesson plans were improved - through the use of the Q&A CS-Wizard within LAMS - when compared with their lesson plans designed without the use of this tool. Positive views also expressed by these teachers about the usability of LAMS and the whole experience they acquired during their participation in the said experiment.
