Changes in college students' perceptions of use of web-based resources for academic tasks with Wikipedia projects: a preliminary exploration

Motivated by the need to facilitate Net Generation students' information literacy (IL), or more specifically, to promote student understanding of legitimate, effective use of Web-based resources, this exploratory study investigated how analyzing, writing, posting, and monitoring Wikipedia entries might help students develop critical perspectives related to the legitimacy of Wikipedia and other publicly accessible Web-based resources for academic tasks. Results of survey and interview data analyses from two undergraduate courses indicated that undergraduate students typically prefer using publicly accessible Web-based resources to traditional academic resources, such as scholarly journal articles and books both in print and digital form; furthermore, they view the former as helpful academic tools with various utilities. Results also suggest that the Wikipedia activity, integrated into regular course curriculum, led students to gain knowledge about processes of Web-based information creation, become more critical of information on the Web, and evaluate the use of publicly accessible Web-based resources for academic purposes. Such changes appear more conspicuous with first year than with upper division students. The findings suggest that experiential opportunities to grapple with the validity of publicly accessible Web-based resources may prepare students better for their college and professional careers. The study results also indicate the need for integrating multiple existing frameworks for IL into one comprehensive framework to better understand various aspects of students' knowledge, use, and production of information from cognitive and technical perspectives and for a variety of purposes.     

Teachers' Instructional Use of Summative Student Assessment Data

This study examines the extent to which classroom teachers self-report using summative assessment data in formative ways to shape instruction. A Web-based survey was administered to elementary, middle, and high school teachers in a large, suburban school district in central Virginia. Teachers reported administering a variety of summative assessments with varying frequency, and analyzing data at the aggregate level, most often using central tendency statistics. Useful methods for disaggregating data by content standards or student subgroups were not as frequently reported. Regardless of the methods of data analysis, a majority of teachers reported using assessment results to evaluate their instructional practice and make adjustments to support student learning. The results suggest, however, that teachers engaged in a cursory analysis of student performance fairly regularly but conduct more in-depth analyses less often. The study raises questions about how teachers can effectively use summative data for instructional purposes.

Examining Online Instruction in Undergraduate Nursing Education

Web-based courses have increased in number as one of the primary modes of distance education in undergraduate nursing programs across the United States. An online survey of 171 nursing faculty in the United States with experience teaching Web-based courses served as the primary data source. Interviews and a review of course Web sites provided additional comparative information. Results of this study indicated online faculty spent significantly more time in planning and implementing a Web course than they did a traditional course. Despite this time commitment respondents perceived the teaching experience to be a successful and effective form of instruction that they felt could be used to deliver any type of nursing course. The online teaching experience was described as both collaborative and highly interactive. Most respondents indicated they preferred online teaching to traditional face-to-face instruction. This positive reaction to teaching online supports the future viability of Web-based instruction at colleges of nursing.

Distance Learning on the Internet: An Exploratory Study

The Internet and Web-based technologies have become a popular platform for the development and delivery of distance learning (DL) programs in an online class setting. While these programs have proven popular with both students and faculty, few research studies have been done to determine the impact of these virtual courses on student learning and/or satisfaction. This article presents the development of a Web-based course model and the results from an exploratory study conducted to determine the effectiveness of this model on student satisfaction. Results from the survey reveal that the students had a positive experience with this Web-based course model. Students were generally satisfied with the online learning environment, appreciated the flexibility of being able to access course material any time and any place, and were satisfied with quality and course content.     

College Student Responses to Web and Paper Surveys: Does Mode Matter?

We examined the responses of 58,288 college students to 8 scales involving 53 items from the National Survey of Student Engagement (NSSE) to gauge whether individuals respond differently to surveys administered via the Web and paper. Multivariate regression analyses indicated that mode effects were generally small. However, students who completed the Web-based survey responded more favorably than paper on all 8 scales. These patterns generally held for both women and men, and younger and older students. Interestingly, the largest effect was found for a scale of items involving computing and information technology.     

Web-based data acquisition

The research work on Web-based long-distance data acquisition (DAQ) is valuable for application to tele-detection machine faults. With an expert system for machine fault detection, faults in a distantly located machine can be diagnosed through the internet. The distant user logs on to the expert system Web page, fills in the requirements, and starts-up the diagnose process. The system then connects to the DAQ server that is installed in the machine, samples data required for diagnoses through the internet, and sends back diagnose results. In such a long-distance system, Web-based DAQ plays an important role by automatic sampling and transferring of data through the internet. We have built an experimental data acquisition system using a National Instruments AT-MIO-16E-10 board running under Ch language environment. In this experimental example, the user can acquire data online. The principle of this experimental method is introduced in this paper. A detailed programming technique is described with an example.

Guiding Principles for Facilitating Higher Levels of Web-Based Distance Teaching and Learning in Post-Secondary Settings

The purpose of this study was to develop guiding principles to encourage higher levels of teaching and learning in Web-based distance education. The research framework used Zetterberg's (1962) model for change. Data from semi-structured interviews with university instructors who had experience in teaching Web-based distance education courses, a focus group interview with educational technologists, a review of related literature, and my own reflective journal, provided insights for the development of teaching and learning principles. A validation process was then conducted from experts and scholars in the field through a consensus survey. The outcome was the development of a model with nine principles that facilitate higher levels of teaching and learning in Web-based distance education.     

Exploring the effects of personality type on perceived satisfaction with web-based learning in continuing professional development

The purpose of this study was to determine if there is a relationship between learner personality types and perceived satisfaction when using Web-based instruction for mandatory and self-regulated continuing professional development. Two hundred and four real estate practitioners who participated in a Web-based professional development course completed the Millon Index of Personality Styles (MIPS) instrument and a survey to compare personality type and satisfaction. No relationship was found between personality types and satisfaction when using Web-based instruction. The majority (97%) of participants were satisfied with the course regardless of their personality characteristics.

This paper describes the lessons learned by the authors' experiences and research and offers a specific set of pedagogical and assessment strategies that they have found to be successful in online settings. The authors have found that classes delivered on the Web provide a viable option for professional development of K-12 teachers, and that the learning that occurs is of equal quality to those university courses taught on campus. Web-based courses offer students an opportunity to take courses anytime, anyplace.     

An analysis of multiple factors affecting retention in Web-based community college courses

The current study examined four factors affecting retention in Web-based community college courses. Analyses were conducted on student demographics, student learning styles, course communication and external factors. The results suggest that Web-based courses are more attractive to busy students who are also more likely to fail or drop the course. The combined results from the four factors provided evidence that time management and procrastination are the primary reasons that community college students fail or drop a Web-based course. The study also found evidence that inability to get feedback from instructors may contribute to student dropout and failure in Web-based community college courses.
