  • Implementing Tablet Computers for Investigators at the Pinellas County Sheriff’S Office
    Implementing Tablet Computers for Investigators at the Pinellas County Sheriff’s Office Jim Main Abstract With the exception of a few specialized fields, like cybercrimes, most law enforcement investigators do the majority of their crime solving in the field. Research was conducted to see what other government agencies are doing to make their investigators more efficient in the field. Surveys were conducted with the detectives with the Pinellas County Sheriff’s Office to see what their views are in using tablet computers in the field. The findings of this research show that tablet computers should be implemented in several of the sections for use by the detectives in the field. Introduction Over the past several years, tablet computers have become very prevalent in society. With entry models priced in the range of just a couple hundred of dollars, they have become very affordable to the average person. In 2012, more tablets were sold than laptop computers and by 2014, one in five United States consumers will own a tablet (Horton, 2011). Like civilians, many law enforcement employees have acquired tablet computers. Because tablets can be used for much more than just checking email or browsing the web, law enforcement employees are starting to consider ways that tablets can be used for improving their performance at work. Detectives in the Knox County (Tennessee) Sheriff’s Office Major Crimes and Family Crisis units began using tablets after a detective bought one for personal use and found it useful on the job. One example of how a tablet is useful in law enforcement is when interviewing a witness to a crime involving a car, the tablet has been used to show photos of particular cars to the witness to more accurately report the correct information (Nadeau, 2001).

  • Student Engagement 1:1 Tablet Computer
    1 STUDENT ENGAGEMENT WITH 1:1 TABLET COMPUTER-BASED TEACHING IN THE SECONDARY ENGLISH, HISTORY, AND MATHEMATICS CLASSROOMS: MULTIPLE CASE STUDIES OF A PROGRAM IMPLEMENTATION A dissertation presented by Ugur Kocak to !The School of Education In partial fulfillment of the requirements for the degree of Doctor of Education In the field of Education College of Professional Studies Northeastern University Boston, Massachusetts July 2015 2 Copyright 2015 Ugur Kocak 3 Abstract The use of 1:1 tablet computer-based teaching is a rapidly increasing trend in education that calls for urgent examination, because such a fundamental change in teaching deeply impacts student learning and school budgets. The purpose of this study was to examine how 1:1 tablet computer- based teaching helps or hinders students’ procedural engagement in learning in English, mathematics and history classrooms at a high school. The study employed a qualitative case study method to collect data about this new pedagogical approach without changing existing classroom settings. In these classrooms, the students were expected to take notes on tablets, work on digital copies of practice worksheets, and read text from electronic textbooks. The study found that a large portion of the student population, varying somewhat among subject areas , utilized tablet computers for non-educational purposes during instructional time and teachers were unable to identify such misuse of tablets. The results also reveal that most students would like to continue learning with 1:1 tablet computers because of the tablet computers’ affordances, such as the ability to access multiple resources anytime, anywhere; organize learning materials; and track assignment submissions and grades.
