The purpose of this study was to examine a ubiquitous/pervasive computing initiative from a Community of Practice perspective. It sought to understand how faculty fit technology use into the already paramount goals they had for their students learning, and how that technology’s role became a part of that essential domain. Furthermore, it sought to determine the extent to which a community of practice emerged around the use of technology as a central practice. Using case study methodology with mixed-methods data collection strategies, this study explored practice among faculty participating in a ubiquitous laptop initiative within a pre-kindergarten through fourth-grade teacher preparation program. This program was part of a college of education in a major research university in the southern United States. Doing so involved an examination of the roles of participants, primarily faculty, in the community or communities to identify the primary domains of concern, and to determine to what extent the use of laptops in the classroom has itself become a practice around which a community has emerged. Findings from this study suggested that instructors were, to varying extents, involved in an emerging community of practice that included the use of technology, specifically laptops, to enhance the development of elementary school teachers. This community of practice was heavily dependent upon infrastructure provided by the administration of the college and the ubiquitous laptop initiative. At the same time, these instructors were less involved with a domain that included teaching teachers to use technology, or Technological Pedagogical Content Knowledge (Mishra & Koehler, 2006). / text

The feeling of ownership is a topic of research that has not been addressed as a component in the integration of technology in the K-12 classroom. The effectiveness of this abstract concept in relationship to digital computing is important in the evaluation of one-to-one initiatives in education. This paper reports findings of a research study conducted using a new ownership survey instrument I developed, the Laptop Usage Inventory (LUI). Also administered during the study was the Student Attitude Survey given in a pretest/posttest design. The instruments were administered to seventh and eighth grade students in a north Texas middle school in the 2007-2008 school year. The methodology used to evaluate the Laptop Usage Inventory consisted of Cronbach's alpha and various scaling methods. LUI scale scores were correlated with the results of the Student Attitude Survey to compare students' attitudes toward school before and after using a laptop computer for the school year. Implications for laptop initiatives and for the classroom are discussed and a future research agenda is presented.

For laptop computers, the conventional internal antennas are usually used to operate in the WLAN system only, which can not provide sufficient and seamless services for wireless users. In order to overcome this problem, we propose some internal antennas having dual-/multi-network operation capability in this dissertation. Firstly, we present a combo antenna, which combines two shorted monopole antennas for operating in the WWAN/WLAN dual-network system. Secondly, we introduce a shorted monopole antenna through adding a parasitic element to enhance the impedance bandwidth for operating in the WLAN/WiMAX dual-network system. Thirdly, for achieving the compact-size antenna, we present a composite antenna which is composed of a ceramic chip and a printed radiating portion. Fourthly, we introduce a wideband shorted monopole antenna which can provide a wide bandwidth to cover the WPAN, WLAN, and WiMAX operations, and apply it to the MIMO system. Finally, we propose a coupling-type monopole antenna having multi-network operation capability and a compact size, which is about the smallest antenna for wideband operation in the laptop computer so far.

The purpose of this project was to address the need for integrated technology in schools by presenting LaunchPad as a means of implementing student-owned laptops in the classroom.

The use of computers equipped with Internet access by students during face-to-face (F2F) class sessions is perceived as academically beneficial by a growing number of students and faculty members in universities across the United States. Nevertheless, some researchers suggest unstructured computer use detached from the immediate class content may negatively influence student participation, increase distraction levels, minimize recall of recently presented information, and decrease student engagement. This study investigates graduate students' beliefs about computer use with Internet access during graduate face-to-face lecture classes in which computer use is neither mandated nor integrated in the class and the effect of such use on student recall. Methods include a 44-item questionnaire to investigate graduate students' beliefs about computers and two experiments to investigate the influence of computer use during a lecture on students' memory recall. One experimental group (open laptop) used computers during a lecture while the other (closed laptop) did not. Both groups were given the same memory recall test after the lectures, and the resulting scores were analyzed. Two weeks later, a second phase of the experiment was implemented in which laptop groups were reversed. Results from the first experiment indicated no statistically significant difference in recall scores between the open laptop group (M = 54.90, SD = 19.65) and the closed laptop group (M = 42.86, SD = 16.68); t (29) = -1.82, p = .08 (two tailed). Conversely, the second experiment revealed statistically significant differences in scores between the open laptop (M = 39.67, SD = 15.97) and the closed laptop group (M = 59.29, SD = 26.88); t (20.89) = 2.37, p = .03 (two tailed). The magnitude of the difference in mean scores (mean difference = 19.62, 95% CI: 2.39 to 36.85) was large (eta squared = 0.17). Multiple regression analysis suggests two factors accounted for 10% of the variance in recall scores: (1) students' beliefs about distractions from computer use, and (2) beliefs about the influence of computer use on memory recall. Based on survey findings, participants (N=116) viewed computers and Internet access in graduate classes as helpful academic tools, but distractions from computer use were major sources of concern for students who used computers in graduate classes and those who did not. Additionally, participants believed academic productivity would increase if instructors integrated computer use appropriately in the curricula. Results of the survey and experiments suggest unstructured computer use with Internet access in the graduate classroom is strongly correlated with increased student distractions and decreased memory recall. Thus, restricting unstructured computer use is likely to increase existing memory recall levels, and increasing unstructured computer use is likely to reduce memory recall. Recommendations include changes in the way students use computers, pedagogical shifts, computer integration strategies, modified seating arrangements, increased accountability, and improved interaction between instructors and students.
