Run two search engines at the same time

how do you use the Google search box to get just the right amount of information, analyze it for authenticity, and get it quickly? The new Google Search Lessons are aimed at helping teachers and students learn the inside scoop about skillful searching. Check out nine compelling and practical lessons for students to understand and be successful with the Google search process. The lessons are divided into three modules; Understanding Search Engines, Search Techniques and Strategies, and Search Features. Each topic contains three lessons that build on the skills taught in the previous lesson. Teachers can mix and match lessons depending on the skills they want to emphasize. The lessons provide a guide for teachers, inquiry questions, a slide presentation, and search challenges for students.

We took a new approach to go beyond search to build what we call a decision engine. With a powerful set of intuitive tools on top of a world class search service, Bing will help you make smarter, faster decisions. We included features that deliver the best results, presented in a more organized way to simplify key tasks and help you make important decisions faster.

Looking for the best iPhone® and iPod Touch® Apps but tired of seeing the same lists over and over? AppBeacon is your personal App discovery engine for the iPhone. * Start at the New Apps link above. * See the list of all apps you haven't reviewed. * Don't like an App? Sink it. You'll never be bothered by it again. * Find a gem but not ready to buy yet? Bookmark the App and get updates on prices and new features. * Already own an App? Mark it as Owned. AppBeacon will help you keep track of news and information on it.

A new search engine with less garbage and better results. With less clicking forward and back between results, it is for anyone who wants to get information faster. You can click on an icon to easily search through sites such as Twitter and New York Times.

Connects math, science, technology & engineering to the real world of careers & achievement, so that students can envision a context & purpose for what they are learning.

A mathematics search engine. Includes many "higher ed" links, but still useful and thorough.

"Welcome to the Siemens STEM Academy site: A premier online community designed exclusively to foster achievement in Science, Technology, Engineering, and Math (STEM) through the collaboration of STEM educators, and sharing of "best practices"."

Number Gossip is an outstanding math tool that I learned about from the excellent blog ZarcoEnglish-Tool of the Day. Number Gossip is a search engine for numbers only. Type in any number and you will learn "everything you wanted to know about it but were afraid to ask". For example, when I search for the number 2 I learn: 2 is the smallest prime number, 2 is the only even prime number, the smallest field has 2 elements, for any polyhedron, 2 is the number of vertices plus the number of faces minus the number of edges. I can also learn the rare properties of two, and the common properties of two. Now that is pretty cool!

"Wolfram|Alpha is a free online computational knowledge engine that generates answers to questions in real time by doing computations on its own vast internal knowledge base. Our long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. This can be valuable to educators in many ways. "

More of the wondrous WolframAlpha project. This is the demonstration site that shows some of the most astounding computations that this search engine is capable of doing.

Share this with your math teachers. Let this start the discussion of what it might be like in ten years. Twenty years. It's a game-changer. I hope they all realize that.

Creating an App Inventor app begins in your browser, where you design how the app will look. Then, like fitting together puzzle pieces, you set your app's behavior. All the while, through a live connection between your computer and your phone, your app appears on your phone. Read more... App Inventor is a part of Google Labs, a playground for Google Engineers and adventurous Google users. Send us your suggestions and ideas, but remember to wear your safety glasses while building your apps.

"...what is a "Google-proof question?" It is a question that can not be directly answered via Google (or any other search engine) because it requires, analysis, interpretation, and investigation. Writing such questions can be challenging. A helpful tool is Bloom's Taxonomy. "

" The answer to almost any question is available within seconds, courtesy of the invention that has altered how we discover knowledge - the search engine. Materializing answers from the air turns out to be the easy part - the part a machine can do. The real difficulty kicks in when you click down into your search results. At that point, it's up to you to sort the accurate bits from the misinfo, disinfo, spam, scams, urban legends, and hoaxes. "Crap detection," as Hemingway called it half a century ago, is more important than ever before, now that the automation of crapcasting has generated its own word: "spamming.""
