How BioEd Online could help me? You can find educational videos, read supplementary materials, read about recent news and hot topics in biology.

What is good and what is bad about it? News section with hot topics and urgent discoveries is engaging. Videos and materials are also helpful, however, they cover limited number of topics. As for the website itself, the design looks a little outdated, however it is well-structured.

The next source we want to talk about is BioEd Online – «Science Teacher Resources from Baylor College of Medicine». In fact, BioEd Online is created for teachers to help them make their classes better. However, we think that this website could be used by students as well. As you see, there are different sections on the website. Videos could help you to remember topics you studied at class and to prepare for the test. Library with different reading materials can be valuable if you are working on your research paper, group project or individual essay.

How DOAJ could help me? Look for articles in biology for any assignment.

What is good and what is bad about it? There are 3 million articles that you can find, the majority of them are on biology and medicine. The search process is clear and easy. As for weak points of DOAJ, we could mention that this search engine is for academic articles search only .

Practice shows that students often don’t know how to search information they need for their assignments. There are a lot of databases and academic search engines that you could use in your studies. We want to present you one of them – Directory of open access journals. This is probably the best free source to look for biology related information.
