Final degree projects (FDPs) are a challenging stage in the academic life of students, but it is also a challenge for teachers as FDPs could represent a key link between university and professional environment, including scientific research. In a way, this stage is a transition for students, where they can achieve maturity in many aspects such as critical thinking, autonomy, self-confidence, or ethics, among others, getting ready for the real world where mentorship might not be as usual as expected. In other words, FPDs (apart from the obvious academic benefit) could be an essential experience to shape different appreciated values that could help our students to make right decisions in the future. However, according to our experience, students usually present worrying lacks in many facets, including research ethics, which is the subject of this work. Thus, our goal is to show an update of our didactic unit devoted to the suitable development of FDPs, focusing on research ethics and some basic guidelines concerning different aspects such as authorship, plagiarism, the use of artificial intelligence, etc. As a result, high-quality FDPs were obtained, and the students learned to avoid ignoble practices such as plagiarism or reference lumping.
