Reading your post has prompted me to research further on the subject with a view to enhancing my instructional design skills. Instructional designers should strive to design learning materials that have the potential to reduce the cognitive load of learners, thus making the learning process effective. The manner in which learning material is organized and presented plays a part in reducing cognitive load (Chandler & Sweller, 1991), for example appropriate combination of audio and visual techniques. After going through the literature, I have also noted that while it is important to provide novice learners with instructional guidance in order to reduce possible cognitive overload, this technique can be counter-productive to experienced learners (Artino, 2008). Paas, Renkl and Sweller (2003) suggest that as the level of leaner expertise increases, it is appropriate to decrease instructor control and increase learner control in the learning process.

]]> Comment on Apple Blocks Adobe’s Flash-to-iPhone Compiler in Latest SDK Agreement by admin http://raypastore.com/wordpress/2010/04/apple-blocks-adobes-flash-to-iphone-compiler-in-latest-sdk-agreement/comment-page-1/#comment-28 admin Sun, 11 Apr 2010 13:36:19 +0000 http://raypastore.com/wordpress/?p=190#comment-28 Steve jobs responds: If that were to happen, there’s no lock-in advantage. If, say, a mobile Flash software platform — which encompassed multiple lower-level platforms, running on iPhone, Android, Windows Phone 7, and BlackBerry — were established, that app market would not give people a reason to prefer the iPhone. .... And, obviously, such a meta-platform would be out of Apple’s control. Consider a world where some other company’s cross-platform toolkit proved wildly popular. Then Apple releases major new features to iPhone OS, and that other company’s toolkit is slow to adopt them. At that point, it’s the other company that controls when third-party apps can make use of these features. Gruber also believes that these cross platform compilers rarely produce high quality native apps. Steve Jobs reiterated this point in a followup email: We’ve been there before, and intermediate layers between the platform and the developer ultimately produces sub-standard apps and hinders the progress of the platform.
