Effect of problem based learning with metacognitive scaffolding on achievement in sociology, problem solving ability and social skills among students

In the mid-twentieth century, mass production techniques and mass marketing changed the competitive landscape by increasing product availability for consumers. However, the purchasing process that allowed the shopkeeper and customer to spend quality time interacting with each other was also fundamentally changed. As a result, customers lost their uniqueness becoming an "account number". Shopkeepers lost track of their customers' individual needs as the market became full of product and service options. Many companies today are striving to re-establish their connections to new as well as existing customers to boost long-term customer loyalty (Chen and Popovich, 2003).
