This book presents a methodology for introducing an interactive system in classrooms that makes it possible to save considerably in production costs. It also examines the use of feedback as an intervention for the improvement of both teacher proficiency and student achievement. Research has shown that a scientific breakthrough has been achieved in biological knowledge that can raise society to a new level of development. What this means to science educators is presented. Other chapters analyse the shortcomings of lecture in teaching physics and explores the benefits of using wireless pen-based computing knowledge and the interdependence of science and reading. This book explains the effect of pre-school teachers reading to children on language development. The importance of free symbolic play is also explained. Furthermore, dyslexia is a multifaceted impairment. The book emphasises the importance of noting the differences in the definition of dyslexia when evaluating research. A review of the problems associated with construct and criterion-related validities of developmental dyslexia and issues associated with measurement are explored as well.
