Educational Technology The history of educational technology is marked by the increasing complexity and sophistication of devices, exaggerated claims of effectiveness by technology advocates, sporadic implementation by classroom teachers, and little evidence that the technology employed has made a difference in student learning. Although technology proponents have from time to time claimed that technology will replace teachers, this has not occurred. The typical view among educators is that technology can be used effectively to supplement instruction by providing instructional variety, by helping to make abstract concepts concrete, and by stimulating interest among students.

Curiosity is the main driver of learning. As a basic principle of learning, it makes little sense to force students to memorize large reams of text that they will either begrudgingly recall or instantly forget. The key is to let students focus on exploring an area which interests them and learn about it for themselves. A perfect example of a teaching technique based on self-learning is outlined by http://www.ted.com/talks/lang/es/sugata_mitra_the_child_driven_education.html" target="_blank" rel="noopener">Sugata Mitra at the TED conference. In a series of experiments in New Delhi, South Africa and Italy, the educational researcher Sugata Mitra gave children self-supervised access to the web. The results obtained could revolutionize how we think about teaching. The children, who until then did not even know what the internet was, were capable of training themselves in multiple subjects with unexpected ease. A common technique for exploring self-learning is the use of https://www.goconqr.com/mind-maps/" target="_blank" rel="noopener">Mind Maps. Teachers can create a central node on a Mind Map and allow students the freedom to expand and develop ideas. For example, if the focus is the Human Body, some students may create Mind Maps on the organs, Bones or Diseases that affect the human body. Later the students would be evaluated according to the Mind Maps they have created and could collaborate with each other to improve each others Mind Maps and come to a more comprehensive understanding of the Human Body.

Many students with ADHD have significant difficulties with organization.    They are more likely to respond positively when teachers establish class routines and set procedures and maintain a well-organized learning environment.    Clear rules and advanced planning are keys to success for teachers of students with ADHD. The following organizational supports are particularly useful. Students should be taught to use these tools through teacher modeling and guided practice with feedback before being expected to use them more independently. Assignment Notebook: Provide the student with an assignment notebook to helporganize homework and seatwork.Color-Coded Folders: Provide the student with color-coded folders to helporganize assignments for different academic subjects.Homework Partners: Assign the student a partner who can help recordhomework and other seatwork in the proper folders and assignment book.

School interventions should include a team approach across multiple settings, consisting of bothpreventive and intervention strategies.    Interventions must be based upon assessment data that includes information about the student’s strengths and needs as well as the environmental conditions in which her characteristics of ADHD occur.    Progress monitoring and strategy adjustments are critical to the success of any intervention plan (Wolraich & DuPaul, 2010).
