This book utilizes a Problem-Based Learning (PBL) approach to curriculum development and delivery. PBL is an inquiry-based approach that can be defined as both a curriculum and a process. The curriculum consists of carefully selected and designed problems that engage the learner in the process of acquiring critical knowledge, developing proficiency in problem solving, engaging in self-directed learning, and participating in collaborative teams. Problem-Based Learning (PBL) is a multidisciplinary approach that integrates effective teaching and learning practices with computer technology. This curriculum integration process engages students in collaborative research that can be shared in the classroom, across a community or around the globe. So much fascinating information is at the fingertips of learners everywhere; and with the increase in the affordability and availability of technology, more and more learners have access to information sources. PBL approaches give students the ability to retain facts though critical thinking by working through problems logically and making connections to the real world. PBL features open-ended and cooperative activities that deal with real world issues and scenarios.
