izzit.org: Free Educational Videos The Problem With Measuring Digital Influence Editor’s note: Dr. Michael Wu is the Principal Scientist of Analytics at Lithium where he is currently applying data-driven methodologies to investigate and understand the complex dynamics of the social Web. Social media is a required avenue for brands to engage their customers. However, social media engagement is primarily based on conversations and personalized interactions that are difficult to scale. Influencer marketing provides brands with the leverage to reach many by engaging only a few illusive influencers. This strategy depends on the accurate measurement of people’s digital influence, so brands can figure out who they need to engage. One of the reasons that brands don’t understand digital influence is because they don’t seem to realize that no one actually has any measured “data” on influence (i.e. explicit data that says precisely who actually influenced who, when, where, how, etc.).

Scribblar - Free Interactive Online Whiteboard Two Hands-on Economics Lessons for Students Yesterday I had a conversation with a teacher who had developed his own stock market game for his middle school social studies course.

How to Measure Someone's Social Influence Social Influence. How do you measure it? I asked this question on LinkedIn Answers and got a range of responses. Some said by looking up someone’s Klout score. Some said by the number of followers someone had. To me, you measure someone’s social influence, but it’s based on your opinion and what you look for. Social influence should be determined by a combination of factors. Take a look at the person’s fanpage. Subscribing to someone’s personal profile is still fairly new. Now let me preface this, there are people who buy Twitter followers. LinkedIn Endorsements are still fairly new. This is going beyond a Facebook page’s “talking about this”. Simple. See, you knew this would enter in somewhere. Kred measures someone based on their Twitter and Facebook activity. PeerIndex is another site that scores you on your social media. Very simple. These are my 10 factors that I use to determine social influence. So tell me, what do do to measure someone’s social influence? A Tour of Klout

Financial Literacy, Taxes, and Economics Lessons This evening I opened an email from Edutopia that contained a nice, simple infographic about the importance of financial literacy. The infographic has some basic statistics about the debt load carried by young people and how personal finance education can change those statistics. The infographic is really just a promotion for Edutopia's other materials about financial literacy. It also reminded me of some other resources for teaching students about personal finance and taxes. As the income tax filing deadline is just a few days away in the United States, I thought it would be good to highlight some resources for teaching about taxes too. The IRS website, Understanding Taxes, is a good source of lesson plans and individual learning materials about taxes and budgets. PBS Kids has a great lesson plan for introducing young students to the concepts of budgets and taxes. At Where Did My Tax Dollars Go? Just where does of all the collected tax revenue go?
