An Architectural Approach for Reducing Power and Increasing Security of RFID Tags

Radio Frequency Identification (RFID) technology is currently employed for a variety of applications such as RFID-based wireless payment, healthcare, homeland security, asset management, etc. Due to newer privacy requirements and increasingly secure applications, typical RFID tags are required to expand security features such as data encryption and safe transactions. However, RFID tags have extremely strict low-power consumption requirements. Thus, reduced power consumption and secure data transactions are two main problems for the next generation RFID tags. This dissertation presents an architectural approach to address these two main problems.

A Co-operative Web Services Paradigm for Supporting Crawlers

To address these issues, we present a collaborative approach where the Websites coordinate with the crawlers to provide increased capabilities. Our system supports a querying mechanism wherein the crawler can issue queries to the Web service on the Website and to answer these queries, we exploit valuable information present in the Web logs and file system on the Web server. We also investigate a novel URL ordering algorithm that exploits the access count information present in the Web logs on the individual Websites. In particular, we develop URL ordering algorithms based on internal and external counts and compare them empirically with a breadth first search crawl.

A Comparison of Student Perceptions of Learning in Their Co-op and Internship Experiences and the Classroom Environment: A Study of Hospitality Management Students

Unlike many other studies, this study investigated student perceptions of learning in both their classroom environments and their experiential learning assignments at the same time. This allowed the researcher a unique opportunity to compare and contrast each learning environment and identify specific benefits for each.

A Framework for Active Learning

A prototype of such a framework is developed with an additional construct known as Show Me Mode that enables students to view animations of the execution of an algorithm.

Storytelling as an Active Learning Strategy in Introduction to Psychology Courses

Phenomena of psychology do not occur in a vacuum nor should the instruction of psychology. Previous research indicated a movement towards active learning, which affords instructors and students of psychology the opportunity to break down classroom barriers to bridge academia and real life. Although a substantial amount of research has supported the use of active learning, a gap exists in identifying both the effectiveness of specific techniques and the use of storytelling across disciplines. Specifically, little research has focused on the effectiveness of storytelling as an active learning strategy in introductory college courses, especially in comparison to traditional methods. Therefore, the purpose of the present study was to examine the effective use of active learning through storytelling as a means to foster connections between conceptual material and real world application. Participants in this repeated measures, quantitative study included 109 college students who were randomly assigned to one of three experimental learning conditions: No Storytelling, Instructor Story Only, and Instructor Story Plus Student Response. Analyses of variance indicated no significant difference on test scores at Pretest and Posttest 2; however, significant differences were found at Posttest 1. Social change implications for this study may include promoting active learning through storytelling that has the potential to transform learners, instructors, campus environments, online learning communities, and curriculum development practices across higher education.

Art in Action: Traditional Art Appreciation Moves Into Active Learning

The 21st century age of information has arrived and many higher education faculty instructors are still stuck in the 20th century, age of industrialism. However, twelve years ago a small south Texas community college was consciously founded upon active-learning student-centered models of teaching. In accordance with the college plan, all incoming faculty hired had to be willing to change their traditional professor persona and move away from lectures. This qualitative phenomenological study looks at how the art appreciation teachers in this college made the transition from the traditional slides and lecture format to a student-centered active learning teaching environment. The interviewed volunteers consisted of all different ages, ethnicities, levels of teaching experience and who were hired on at different times - thus ensuring a rich cross selection of change experiences to explore.

Scientific studies based on human learning are leading institutions and
instructors toward a more active learning environment. As Meier (2000) notes, “

Theoretical Foundations of Active Learning

I study the informational complexity of active learning in a statistical learning theory framework. Specifically, I derive bounds on the rates of convergence achievable by active learning, under various noise models and under general conditions on the hypothesis class. I also study the theoretical advantages of active learning over passive learning, and develop procedures for transforming passive learning algorithms into active learning algorithms with asymptotically superior label complexity. Finally, I study generalizations of active learning to more general forms of interactive statistical learning.

A Comparison of Traditional and Active Learning Methods: An Empirical Investigation Utilizing a Linear Mixed Model

Three topics (in the introductory business statistics course) and five instructors covering seven class sections are used with three different experimental teaching methods. Method topic combinations are randomly assigned to class sections so that each student in every class section is exposed to all three experimental teaching methods. A linear mixed model is utilized in the analysis. The effect of method on student score was not consistent across grade point averages. Performance of students at three different grade point average levels (high, middle, low) tended to converge around the overall mean when learning was obtained in an active learning environment. Student performance was significantly higher in a traditional method (versus an active learning method) of teaching for students with high and mid-level grade point averages. The effects of the teaching method on score did not depend on other student characteristics analyzed (i.e. gender, learning style or ethnicity).

Active learning using cooperative approaches is well suited for preparing
business students because of its social, teamwork, and real-world applicability (

The Effect of Active Learning Exercises on Academic Performance and Nonintellectual Learning Factors

Two graduate student instructors and four courses of general psychology were recruited for participation. SAT scores, course grades, student ratings of teachers, and measures of nonintellectual learning factors were collected for analysis.

Active learning, when considered as a compound word, can be simply
understood as “being in physical motion” while in “the act, process, or experience
of gaining knowledge or skill” (Dictionary.com, n.d.). Researchers, on the other
