This article is taken from http://www.openculture.com which contains fantastic open source resources for you, me and our kids. By way of example, it was World Water Day the other day which I only knew because there was an offer by government to subsidise the purchase of rainwater tanks.

At a conference last year, over one third of the participants had an iPhone. Half my nieces and nephews have an iPhone. Half the people in the lift at work who want to avoid i-contact, look at their iPhone... so here is the borrowed article...

Since the release of the iPhone App Store, numerous sources have commented on the potential of educational apps. While these apps can’t compete with the general popularity of gaming and leisure apps, there are a number of educational apps that mobile learners will find handy.

Continue on to view the top free iPhone apps for education.

Given the iPhone’s capacity for audio and visual learning, it’s no surprise that many of the most popular education apps focus on language learning. Free Spanish Tutor, the most downloaded free app, comes from the 24/7 Tutor series, and it’s described as follows:

24/7 Tutor provides a set of the most common and useful words and phrases, organized by topic and category. An audio recording by a native speaker is available for each element. These are all integrated into a multi-function learning system, with measurement of progress tracked by quiz scores. A priority-filter mechanism is provided that allows you to optimize your efforts by focusing on those items most needing additional practice.

Another highly popular free language app is Japanese Phrases FREE. Like 24/7 Tutor, it also offers a paid version with additional content and features. There are also free applications available for French, Italian, Arabic, German, Korean, and Russian.

The second most popular free education app is Maps of the World, which allows users to browse 20 historical maps. While this won’t be useful to someone who needs directions, it’s a fun diversion for students of history and geography.

myHomework is an interesting student productivity app that allows students to keep track of their homework, classes, projects and tests while interacting with a visually appealing notebook-like design.

Other popular free apps cover the areas of SAT prep (Vocab Quiz SAT lite), spelling (Spel It Rite), and chemistry (The Chemical Touch lite).
