In the last few decades, different teaching methodologies have been proposed to promote more active learning of students. However, it is still essential to understand the practical implications of the theoretical concepts incorporating additional methodologies, for example, problem-based learning. This methodology could include practises focused on students' programming or on using appropriate software tools. For more meaningful learning, the use of a graphic tool instead of programming provides more insight into those concepts throughout a simple and practical resource. Taking this into account, a software tool has been developed in addition to theoretical sessions in the context of a subject of the Degree in Computer Science, where the learning objectives are related to the representation and compression of multimedia content. In addition, this tool allows to configure useful exercises for these practical sessions, such that students can experiment and analyse the results from a visual perspective. The results of the surveys show a high degree of satisfaction of students, who highlight that the tool has helped them to better understand the curriculum content. In addition, there are signs of improvement in the academic results corresponding to the evaluation of performance with such software.

用于教学数字图像表示基础的教育图形工具

在过去的几十年里，已经提出了不同的教学方法来促进学生更主动的学习。然而，理解包含额外方法的理论概念的实际含义仍然很重要，例如基于问题的学习。这种方法可以包括侧重于学生编程或使用适当软件工具的实践。对于更有意义的学习，使用图形工具而不是编程可以通过简单实用的资源更深入地了解这些概念。考虑到这一点，除了计算机科学学位主题的理论课程之外，还开发了一种软件工具，其中学习目标与多媒体内容的表示和压缩有关。此外，该工具允许为这些实践课程配置有用的练习，以便学生可以从视觉角度进行实验和分析结果。调查结果显示学生的满意度很高，他们强调该工具帮助他们更好地理解课程内容。此外，与使用此类软件进行绩效评估相对应的学业成绩也有改善的迹象。
