Perkins Activity and Resource Guide Chapter 2 – Foundations of Learning Language, Cognition, and Social Relationships [EPUB ebook] 

Foundations of Learning: Language, Cognition and Social Relationships The Perkins Activity and Resource Guide is a handbook for teachers and parents of students with visual and multiple disabilities. In this chapter we have combined the topics of communication, social relationships, and cognition, because it is critical that teachers think of these as integral parts of each activity and not as isolated classes to be taught at a specific time during the day. These areas must be addressed throughout the day in all activities.
