NETS- Which one is most important?

During the course Creative Teaching Techniques and Utilisation of Multimedia within the International Teaching MEd @ Framingham State University, we looked at the ISTE Standards for students (also known as the NETS). While all 6 are important in tailoring digital citizenship, at this moment I think that the most important one for me and my class is standard no. 3, which discusses the research process and information fluency. 
While I was teaching 3rd Grade, I noticed that many of my students were feeling overwhelmed whenever they needed to conduct any research, either because of the great amount of information they could find on a topic, or because of the lack of it. I realised how vital it is to provide students with the right, age-appropriate means of researching, including relevant databases, search engines, and criteria for evaluating websites.
This made me realise that I still have a lot to learn myself in order to help my students learn how to be effective researchers. I have to better myself  first to help my students better themselves. But that is what teaching is all about, isn't it? Learning so you can help others learn.
