Due to its open-ended nature, project-based learning (PBL) is a suitable methodology to achieve student motivation and enrich creativity skills. This article describes the design of PBL activities in two undergraduate courses on digital signal processing techniques. The academic context is a bachelor's degree in telecommunication engineering at the Universidad de Extremadura in Spain. Full specifications for five project proposals that other instructors could use are explained, including an in-depth analysis of one of them in relation to the learning outcomes. The results of a survey designed to gain insight into students' perceptions of the PBL process are provided. All of the participants agree or strongly agree that PBL improves the long-term retention of knowledge and provides learning with a more practical orientation toward real goals than conventional learning. Also, 91% of them consider that PBL motivates them more than traditional methodologies. The instructor's conclusions after the project development and assessment are that PBL considerably helped the students to think more creatively and increased their motivation in comparison to other activities.

多学科基于项目的学习：提高学生学习信号处理的动机


由于其开放性的性质，基于项目的学习（PBL）是一种适合激发学生积极性和丰富创造力技能的方法。本文介绍了数字信号处理技术两门本科课程中PBL活动的设计。学术背景是西班牙埃斯特雷马杜拉大学电信工程学士学位。解释了其他教师可以使用的五个项目提案的完整规范，包括对其中一个与学习成果相关的深入分析。提供了一项旨在深入了解学生对 PBL 过程的看法的调查结果。所有参与者都同意或强烈同意，PBL 可以提高知识的长期保留，并为学习提供比传统学习更实际的目标导向。此外，91% 的人认为 PBL 比传统方法更能激励他们。教师在项目开发和评估后得出的结论是，与其他活动相比，PBL 极大地帮助学生更具创造性地思考并提高了他们的积极性。
