Google has a couple of other options that may prove useful in your searching.
You can find it under the More menu option on the main Google search page.
Google does a fair job keeping track of academic publications of all sorts. There are advanced options available to help you narrow your searches. Your search may also pull up a book or two. If the book has been digitised by Google you can then use Google books to find the text or ideas of interest.
Google also tracks citations, that is papers that cite or reference the paper or book. So if you find an article or book of interest, it is often worth having a look at the papers that have cited the paper or book.
Google Books can sometimes be handy if you need to either locate a quote or find a reference in a section of a book you don't have access to. You can search for text in Google Books. It is a project that aims to digitise every book on the planet! However, it does not mean you can simple read a book online (which is not a good idea). Only portions of the book will be made available to you.
Google alerts is a facility offered by Google in which you can decide a search term, e.g. "classroom management" and tell Google to send you an email as frequently as daily if you wish for all of the times it finds a new mention of that term. Now obviously you'll need to be very careful with deciding the search terms or you will fill your mailbox with junk! You can always try out an alert and if it generates too much stuff it can always be deleted. I find that a key author's name, if it is not too common a name, is not a bad way to keep an eye on some parts of a field. You can find the alerts, other than if you use Google Scholar, under the Even More menu of Google.

A blog which is short for web blog is a place where people or groups choose to write on areas of interest. There are blogs for almost everything you could possible imagine and then some. The reason for pointing to blogs and being able to search only blogs is that if you can find one or two blogs that are close to your area(s) of interest then they can often work out to be your very own unpaid research assistants, that is they will find stuff, report on a book or a conference or other blogs they come across that is related to their interests which are close to yours. You can waste your life reading these things so again, you have to be pretty ruthless in what you choose to keep an eye on. Some blogs offer an RRS (really simple syndication) feed which means you can access the blog posts, often in an abbreviated form using RSS reader software or your email (if it has that facility).
I know many research students who maintain blogs. You may locate one or two who have similar interests to your own and may be able to establish a relationship with them to share ideas, articles, or information.
Other Google stuff
Google Trends is also worth a look if your topic is one that is fairly topical. You can track over time the frequency in which a term is mentioned in searches, e.g. national curriculum. The best way to get an idea of what it does is to have a play.
Google ngram viewer is similar but draws on the data that Google has acquired by scanning most of the books on the planet. You can search for phrases and it will given you a mapping, over time, of the occurrence of the phrase in books. You can also compare phrases and the output provides linsk to google book searches for the phrase, i.e. you can go and look at particular books. For the adventurous, you can download the data about the phrase.
Google also provides free facilities for sharing such as blogger (for your own blog), docs, for sharing the writing of documents and so on. These are found under the even more menu.
