Useful Instructional Strategies for Literature-Based Instruction. There are many different strategies that research has shown are effective in literature-based instruction (Cooper, 1993). These include scaffolding of instruction, modeling, cooperative learning, student choices, self-initiated reading and writing, using different modes of reading, activation of prior knowledge, and student responses to literature.
What Is Peripheral Artery Disease? Peripheral artery disease (P.A.D.) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in the body's arteries, the condition is called atherosclerosis.
PAD is a medical condition caused by blockages of the arteries that provide blood flow to the arms or legs. You may have also heard of this problem referred to as peripheral vascular disease (PVD) or âbad circulation.â In PAD, the arteries become blocked by cholesterol plaque caused by atherosclerosis.ecause PAD-related blockages in the arteries limit blood flow to the legs, patients with PAD have low blood pressures in the ankles. Your physician will use the ratio of the leg pressure to the arm pressure (ankle blood pressure divided by arm blood pressure) to determine whether you have PAD.
