The impact of instructional guidance on learning outcomes in higher biomedical education is subject of intense debate. There is the teacher-centered or traditional way of teaching (TT) and, on the other side, the notion that students learn best under minimal guidance such as problem-based learning (PBL). Although the benefits of PBL are well-known, there are aspects susceptible to improvement. Hence, a format merging TT and PBL (hybrid-PBL, h-PBL) may advance education in biomedical sciences.
Studies that employed h-PBL in higher biomedical education compared to TT and/or pure PBL were systematically reviewed. Specifically, this review addressed the following question: does h-PBL in biomedical sciences result in superior marks and a better student's perception of the teaching and learning process?
We found that the use of h-PBL in higher biomedical sciences was superior compared to TT and pure-PBL. This was evidenced by the higher performance of the students in h-PBL as well as the level of student's satisfaction as compared to TT or pure PBL.
These findings encourage more research on investigating the pedagogical benefits of h-PBL. In addition, these data support an eclectic system in which the pedagogical tools from TT and PBL are used cooperatively in the best interest of the education and satisfaction of the students.
教学指导对高等生物医学教育学习成果的影响是一个激烈争论的话题。有以教师为中心或传统的教学方式（TT），另一方面，也有观点认为学生在最少指导下学习效果最佳，例如基于问题的学习（PBL）。尽管 PBL 的好处众所周知，但仍有一些方面需要改进。因此，一种融合 TT 和 PBL 的模式（混合 PBL，h-PBL）可能会促进生物医学科学的教育。
系统回顾了在高等生物医学教育中采用 h-PBL 与 TT 和/或纯 PBL 进行比较的研究。具体来说，本次综述提出了以下问题：在生物医学科学中使用 h-PBL 是否会导致更高的分数和学生对教学过程的更好感知？
我们发现，在高等生物医学科学中使用 h-PBL 优于 TT 和纯 PBL。这一点可以从 h-PBL 中学生的表现以及与 TT 或纯 PBL 相比学生的满意度水平得到证明。
这些发现鼓励更多地研究 h-PBL 的教学效益。此外，这些数据支持一种折衷的系统，即在 TT 和 PBL 的教学工具的基础上，为了教育和满足学生的利益而进行合作。
