Book Five of the Learning to Apply Series, is a consolidated version of two former manuals, titled Fieldworks (Duncan, 2010) and Applying Research (Duncan, 2010), used in 10th and llth grades at West College High School. This reform, at the suggestion of Director Cynthia Delgado, is consistent with the fact that the undergraduate paper that West's students prepare is developed precisely over these two academic years as a single project. During level ten-eleven, students consolidate their capacity for self-education -learning how to learn, learning how to comprehend the subjects studied, and learning how to apply the knowledge acquired when faced with today's challenging and changing reality, thereby achieving the final aim of the Series. Students will design and develop an undergraduate report, ("tesina" in Spanish) which is the final research-report that they are expected to present as part of their graduation process. The tesina is basically an individual study that each student carries out to demonstrate his capacity to formulate a problem, confront it with a basic theoretical framework, using proper methodology and adequate techniques required to close this stage of his academic experience. The course is divided in two parts: Fieldworks, designed to recap formerly acquired knowledge, to set up a professionally oriented research plan and to complete preliminary investigation. The second part, Applying Research, guides students to the completion of their investigation and to the delivery of a competent report.
