Language materials are tools (such as texts, activities and complete textbooks) utilized for language learning; in fact, the degree of language acquisition is largely dependent on the types of materials used in the classrooms. Thus language materials have been an important focus of literature in the past two decades. “Many of the books published are ‘how to’ books… but they are not based on research studies into materials” (Garton and Graves, 2014: 1). In contrast, this book presents a fresh outlook about the field of second language materials by illustrating and applying the theoretical assumptions in research involving comprehensive analysis of the ESL textbook scenario in Pakistan for the first time. The opening chapters encapsulate the concepts focusing on materials and other related areas and specify the practices deemed to be effective for second language learning. The main chapters discuss the findings highlighted through a recent study critically investigating the different educational aspects (primarily the textbooks) which have influenced the English language teaching context in Pakistan.
