Chapter 6: Explaining Reading Comprehension: Models of Reading. This chapter reviews the major current model of reading comprehension that underlie much of current research on reading comprehension, both in L1 and L2 contexts. The chapter quickly notes more metaphorical explanations and then moves on to models and frameworks that are key for interpreting reading comprehension research: the Simple View of Reading, the Construction-Integration Model, the Landscape Model, the Verbal Efficiency Model, and the Reading Systems Framework Approach. The chapter closes with a specific discussion of L2 reading comprehension as interpreted by current models, and finally with implications for instruction.
