    • A look into students’ interpretation of electric field lines

      Campos, Esmeralda; Zavala, Genaro; Ramírez-Montoya, María Soledad (IGI Global, 2017)
      This chapter is focused on learning different ways in which undergrad students in introductory Electricity and Magnetism (EM) courses interpret and use electric field lines diagrams to describe the electric field at any point in space. Due to its abstract nature, the electric field is a concept that tends to be misunderstood. Several representations of the electric field may have a different effect on the correct understanding of the electric field; such as the use of vectors and the electric field lines diagram. A correct interpretation of these representations should, theoretically, lead to a better understanding of the concept of electric field, and to a correct use of concepts such as the principle of superposition, electric force and repulsion. The problem that this research tackles is to identify how students interpret electric field lines, and what effect their interpretations may have on the conceptual understanding of the electric field.
    • Quantitative Analysis of U.S. News & World Report University Rankings

      Fangmeyer Jr, James Andrew; Galeano, Nathalie; Cantu-Ortiz, Francisco J.; Tecnologico de Monterrey (CRC Press, 2017-10-26)
      This chapter reviews the impact of U.S. News university rankings in science and culture. Section 12.1 recounts the magazine’s ranking history and recent activity. Section 12.2 explains methodology from the BGU ranking. The scientific relevance of U.S. News university rankings is developed by means of a literature review in Section 12.3. The first part of Section 12.3 is a Scientometric review of 233 documents related to U.S. News rankings. Questions asked include, Who publishes about U.S. News? Which academic disciplines research U.S. News? Where is research on U.S. News published? The second part of Section 12.3 organizes the contents of the articles to understand perspectives and preoccupations around the rankings. The story would not be complete without a supporting cast; U.S. News is compared with other international rankings in Section 12.4. Finally, this chapter concludes in Section 12.5 by predicting future directions for global university rankings and U.S. News in particular.
