One paradigm that has beenwidely adopted in industry is MapReduce as implemented in open-source tool, Hadoop [3].Although these systems are based on many years of research work, the conceptual framework onwhich these systems were built differs largely from what could be found in the earlier researchwork and education curricula. University courses available today are largely focused aroundvarious areas (some from repackaged content) that cover some selected parts of Big Dataspectrum, mostly: data mining, distributed systems and most recently data science [5][6][7].We believe that the pedagogical approach used by related education

process to achieve the same goals.1. Introduction1.1 AttitudesEducators regularly assess their students’ work with carefully constructed tools. There are manytools available such as tests, projects, and homework assignments. These tools are used based onthe task at hand and new tools are developed as necessary. Such assessments assist the educatorin determining the student’s degree of subject mastery. Formative assessments point out gaps ina student’s understanding and provide opportunity for improvement. Final, summativeassessments involve the review of not just the final course average, but also the progress thestudent has made, the consistency of effort, and additional factors.

Although there is alot of research to conduct regarding visualization as a tool for teaching and learning, there is a consensusin terms of the effectiveness of catering to this style of learning.

Though there is not a cure for the disease,physical therapy (PT), particularly when applied to the upper extremities, has been shown toameliorate some CP symptoms 1, 18. Despite the demonstrated effectiveness of PT, patientadherence to therapy is problematic, as patients tend only to maintain their regimen whileactively enrolled in a therapy program 2.
