The course conceptually describes the need for a change in the field of toxicity testing replacing the decades-old cruel method of animal testing. The availability of instructors from a vast variety of areas is the most important asset of this course. THIS IS ONE OF THE BEST COURSES EVER!!

Very nice and the teachers explanation are clear . It’s very interesting, specially if you work in the research-lab section

A very well-taught course with lots of useful information. I highly recommend it.

Awesome course! Highly essential information for all toxicologists!

Excellent Information. I would say every toxicologist should once go thorough this wondaful series of lectures covering almost all the aspect of Toxicology. Very well designed course. My best wishes to all the facilitators for their hard work. Looking forward some similar course from Johns Hopkins University.

Thanks for the opportunity to be part of this course. With this course, I have been able to understand the current trend in the field of Toxicology where animal testing has giving a way for the new advance technology such as cell culture, omics, highthroughput test.

The course was fabulous and was equally effective and it is the ultimate need of today . The idea of paradigm shift in toxicology to in vitro toxicology testing was and is realistic and much more helpful. I owe my sincere thanks to all the professors of this course.

This was a very well run course with helpful activities. I have used the material in my profession. It is not a lightweight course; some courses you can breeze through, but this one will take some effort and time. But it's well worth it.

one of the best course helps students & researcher about what are challenges faced in toxicology in 21 century and finds the routes to develop new routes and methods for toxicology tests

Very nicely designed course. The instructors offer an excellent and easy to understand overview of a range of promising Tox21 tools and approaches using good examples and illustrations.

I am very happy and glad to part of your course.Thank you

Very good!

Very challenging, only for people having already a background in toxicology.

Helpful Course in Understanding Current trend in toxicological testings

There is really no need for this to be a course. All you need to know is how much to use and where to use portions and which dosages are lethal and which ones aren't.

i recommend this course to anyone especially those in the toxicology field. i have really learnt alot. i thank the team from John Hopkins University for making this course interesting and easy to learn and understand and i also thank Coursera for making this course available online to people

Es un curso que toca temas relevantes respecto de las tecnologías actuales y futuras en el campo de la evaluación toxicológica de sustancias

very useful course. Really Very informative.

Much needed course for any toxicologist

very helpful and good course

Very informative one

Many Thanks

Good

I think the course was ok, useful overall. But there were several issues: 1) peer graded assignments. I was waited for 3 weeks to get the results and then they were not even fair. I disagree with a score and there were no comments why the score was lowered, but also I felt like I don't want to wait even longer to get a higher grade. Overall, the idea is that someone without knowledge in the subject will grade you is not making much sense to me. Also when I was checking other people assignments it was very obvious they a lot of them just used ChatGPT. Ridiculous. 2) many links in the material are not working and are not updated. 3) some lectures are very good any easy to follow and well structured, but others - just extremely complex, definitely for people who are already deep knowledgeable in the subject. To be honest, I feel that I also have a background that can be useful, I have a PhD in chemistry with a focus of pharmaceutical chemistry, but still some material, especially publications in suggested reading material - I could not follow. Overall it was not clear what was the message of this, feels like this material was there just to fill the space.

No obtengo las calificaciones cuando finalizo el curso, muy mal
