The ideas and lessons in the book help students to communicate with people in faraway places; gather information from around the globe; develop sophisticated research skills; increase knowledge across the curriculum; strengthen creative abilities; develop fluency in keyboarding, reading, and writing; and engage in both cooperative and independent learning.
