Visualization skills are vital for fast and efficient reading comprehension. Visualization Skills for Reading Comprehension builds this key skill quickly and efficiently. Visualizing is the ability to create mental pictures in our heads based on the text we read or the words we hear. It is one of the key skills required for reading comprehension. Students who visualize as they read not only have a richer reading experience but can recall what they have read for longer periods of time. Moreover, having a strong mental image of a text allows students to more accurately and effectively answer Higher Order Thinking (HOT) questions, such as inferencing, prediction, etc. If your learner struggles with reading comprehension, working on visualization skills should be high on your list of priorities. Visualization Skills for Reading Comprehension provides step-by-step activities to quickly build the ability to visualize information while reading.
