This blog has two main themes: one is mathematics and the other is multimedia. The mathematics part will discuss ideas behind mathematical concepts from elementary to undergraduate topics. For now, I will be concentrating on discussing mathematics concepts from Grade 6 through Grade 12, although, from time to time, I might post topics in lower or higher levels. The multimedia part will discuss the use of different media such as text, graphics, sounds, video and animation in teaching mathematics. I will refer readers to multimedia and Web 2.0 teaching resources that can be used in teaching and learning mathematics, and I will discuss how-to tutorials on the use different software, particularly freewares. Unfortunately, most software that will be discussed in this blog are only limited to Windows platform, although many software nowadays are already cross-platform, so Linux and Mac users are invited to check the tutorials from time to time. Hopefully, I would be able to discuss software with other platforms in the future.

Twurdy uses text analysis software to "read" each page before it is displayed in the results. Then Twurdy gives each page a readability level. Twurdy then shows the readability level of the page along with a color coded system to help users determine how easy the page will be to understand. The Goal Twurdy's goal is to provide web searchers with information that is most appropriate for them. This will mean that 10 year olds doing school assignments don't have to click through difficult material to find something they can use. It will also mean that phd students do not have to click through websites designed for kids in order to find what they are looking for.

Evaluating web pages skillfully requires you to do two things at once: 1. Train your eye and your fingers to employ a series of techniques that help you quickly find what you need to know about web pages; 2. Train your mind to think critically, even suspiciously, by asking a series of questions that will help you decide how much a web page is to be trusted. This page is organized to combine the two techniques into a process that begins with looking at your search results from a search engine or other source, follows through by investigating the content of page, and extends beyond the page to what others may say about the page or its author(s).

"How can we best prepare children and adolescents to thrive in the 21st century? This question is at the heart of what every educator attempts to do on a daily basis. Apart from imparting content of knowledge and facts, however, it's becoming clear that the " noncognitive competencies " known as grit, perseverance , and tenacity are just as important, if not more so , in preparing kids to be self-sufficient and successful. To that end, the Department of Education's Office of Technology has released a report called Promoting Grit, Tenacity, and Perseverance"

What is Big Think? bigthink.com is a new and growing website, currently in its beta version, with a simple mission: This is a digital age, one in which a wealth of accessible information empowers you, the citizen-consumer. But where is the information coming from? How accurate and unprocessed is it, really? Ask yourself this: how empowered do you feel debating a television screen or a newspaper?

When you log onto our site, you can access hundreds of hours of direct, unfiltered interviews with today's leading thinkers, movers and shakers. You can search them by question or by topic, and, best of all, respond in kind. Upload a video in which you take on Senator Ted Kennedy's views on immigration; post a slideshow of your trip to China that supports David Dollar's assertion that pollution in China is a major threat; or answer with plain old fashioned text. You can respond to the interviewee, respond to a responder or heck, throw your own question or idea into the ring. Big Think is yours. We are what you think.

"The issues surrounding copyright have never been more visible. But the classroom presents its own copyright-related challenges, for students and teachers alike. How is an educator to know what the rules are? How do those rules apply in the classroom? And how can we make sure that students know the rules as well? To help educators answer these questions, the Copyright Alliance has established the Copyright Alliance Education Foundation. Working with Young Minds Inspired, the Foundation has developed a comprehensive program for teachers. Additionally, we have compiled a library of free curricula that helps teachers of all grades and subject areas incorporate copyright into existing lesson plans."

"The sites are labeled by grade level to help guide you to those that best suit your students.

I tried to find sites that would give students a chance to generate their own original works of art. What could be better?"

"When I asked my students recently how blogging in class makes a difference to them, they had lots to say. Blogging has allowed them to meet students from all over the world and discover new interests.

But for the teacher, bringing blogging into the classroom can be both thrilling and terrifying at the same time. No doubt about it, making the decision to try student blogging is an act of courage. With that in mind, I'd like to share eight things I've learned that can help ensure your brave step is also a wise and successful one for you and your kids. "

"US Copyright laws may be years behind the fast-paced world of social media and blogs, but they still control how a copyrighted work can be used. And while there are aspects of Copyright law that have "gone digital," the Digital Millennium Copyright Act doesn't provide anything new when it comes to explaining how to properly use another person's photos or images online. And because most people won't read the law and even those who do may not understand exactly what it means, I offer you these to help you"
