Around two years ago, Prof. Abu-Zidan came with a plastic triangular shape spatula to one of our morning meetings. He said that
It was not a surprise for me seeing such a sample proposed from a person who always thinks simple educational options. The process which started that day improved with the addition of play dough into the core discussions. After two years of discussions their values in ultrasound skills education, we wrote a methodology paper which accepted by World Journal of Emergency Surgery with unexpectedly valued comments by reviewers .

As a bottom line, this article says there is no need for expensive simulators for ultrasound training. The tools which can be created less than 10 USD and used repeatedly can help to teach ultrasound enjoyably and effectively, especially in the limited resourced settings.
Students understand the actual views and windows easily while they fan or tilt the knife. In addition to this practice, when the play dough added, the joy starts. Students create normal and pathologic anatomical samples and apply different angles with their triangular shape knife. This practice helps them to understand more about the image that they acquire on the screen. Then, real ultrasound practice follows on real patients or human models. You can imagine how it is enjoyable and effective for their learning. One of the advantages of this simple, cheap simulator is that its reusability. Less than 10 USD, but you can use it for 70-100 students during all academic year.
We found only three educational papers/posts about play dough usage for medical education. The first, Dr. Eftekhar and his group published a paper showing effective use of play dough for visualization of complicated cerebral aneurysm anatomy . The second, Dr. Herur and her team published an article regarding play dough modeling of neurologic anatomy by students as an active learning tool . The third, Dr. Adam Bystrzycki used this method to teach heart anatomy in the Echo in Life Support courses .
Yes, we enjoyed a lot while we were writing this paper. However, applying and testing it during the sessions was amazing. And, I shared the article in social media which I have no significant number of followers. However, even with this small attempt, we started to hear some feedback, recommendations, and samples shared by other groups and individuals who are using these tools.
Even one of the biggest ultrasound congresses, WINFOCUS, announced that they are going to use these simple teaching tool in their student course the first time.
These are promising news.
As we all know, radiology and emergency medicine are the two leading specialties that implement ultrasound training into the student curriculum [5, 6]. As the iEM Education project, it is our aim to promote emergency medicine and provide free educational resources. Therefore, we just wanted to share in case you may think to use it in your ultrasound sessions.
This tool is so cheap. It can be created by anyone, anywhere, anytime. We are looking to hear more feedback from world ultrasound experts regarding the effectiveness and joy of this tool.
