Delivery options can influence performance. Students expect Nintendo-like responses to every click of the mouse. If you are considering software on a CD-ROM, chances are you won't have to worry about performance unless you will run the software on a slow computer. For Internet-based applications, remember that different users have different expectations for performance, and different web browsers and modes of Internet access produce different results. If you are going to use an application that contains extensive use of graphics, make sure the bandwidth can handle it.
Slow applications are frustrating.
Assessments should be well designed and should support instruction appropriately. Assessment can play a powerful role, from providing learning plans for individual students to evaluating their performance. Look for types of assessment that promote thinking, not guessing. Feedback should be tailored to the answer. For incorrect responses, the correct answer should be presented along with further information or instruction about the specific topic.
