形成性评价和迭代原型似乎是一个有趣的方法来构建协作学习系统。我们创建软件系统的方法包括迭代分析、规范、实现和评估的连续阶段。最后，这个过程变成了一个五遍循环，在两年内完成，在第三和第四个原型版本之间进行了重大的重新实施。我们描述了每个版本的主要功能，以及随后的评估技术。对第一个周期进行了更详细的介绍，并对其余周期的相关方面进行了总结。每个评估包括学习活动的设计，原型的配置，以执行的经验，设置和观察与真实的学生和导师进行的活动，最后得出的结论，包括考虑下一个设计阶段的改进。
Formative evaluation and iterative prototyping seem an interesting approach for building collaborative learning systems. Our approach to create our software system consisted on iterating successive stages of analysis, specification, implementation and evaluation. At the end, the process turned out to be a five-pass cycle, carried out in two years, with a major reimplementation between the third and the fourth prototype version. We describe the main features for each version, as well as the evaluation techniques followed. The first cycle is presented in more detail and relevant aspects are summarized for the rest. Each evaluation includes the design of a learning activity, the configuration of the prototype to carry out the experience, the set-up and observation of the activity performed with real students and tutors, and finally the drawing of conclusions including the improvements to consider for a next design phase.
