	The Validity of Health Claims on the World Wide Web: A Case Study of the Herbal Remedy Opuntia Date: 2000-05 Creator: Veronin, Michael A. Description: The World Wide Web has become a significant source of medical information for the public, but there is concern that much of the information is inaccurate, misleading, and unsupported by scientific evidence. This study analyzes the validity of health claims on the World Wide Web for the herbal Opuntia using an evidence-based approach, and supports the observation that individuals must critically assess health information in this relatively new medium of communication. A systematic search by means of nine search engines and online resources of Web sites relating to herbal remedies was conducted and specific sites providing information on the cactus herbal remedy from the genus Opuntia were retrieved. Validity of therapeutic health claims on the Web sites was checked by comparison with reports in the scientific literature subjected to two established quality assessment rating instruments. 184 Web sites from a variety of sources were retrieved and evaluated, and 98 distinct health claims were identified. 53 scientific reports were retrieved to validate claims. 25 involved human subjects, and 28 involved animal or laboratory models. Only 33 (34%) of the claims were addressed in the scientific literature. For 3% of the claims, evidence from the scientific reports was conflicting or contradictory. Of the scientific reports involving human subjects, none met the predefined criteria for high quality as determined by quality assessment rating instruments. Two-thirds of the claims were unsupported by scientific evidence and were based on folklore, or indirect evidence from related sources. Information on herbal remedies such as Opuntia is well represented on the World Wide Web. Health claims on Web sites were numerous and varied widely in subject matter. The determination of the validity of information about claims made for herbals on the Web would help individuals assess their value in medical treatment. However, the Web is conducive to dubious health information and individuals should exercise caution in accepting health claims unsupported by scientific evidence. > more info \| Use restricted to UNT community

	Attitudes toward Research and Teaching: Differences Between Faculty and Administrators at Three Saudi Arabian Universities Date: 2000-05 Creator: Alsouhibani, Mohammed A. Description: This study is an investigation of the perceived attitudinal differences between administrators and faculty toward research and teaching at three Saudi Arabian universities, King Saud University (KSU), King Fahd University of Petroleum and Minerals (KFUPM), and the Islamic University (IU). The researcher also investigated the effect of several variables, such as rank, university, and academic field on administrators and faculty members' attitudes toward teaching and research. Little Attention has been given to studies that examine the differences between faculty and administrators with regard to their attitudes toward the priorities of teaching and research in Saudi Arabian institutions. Also, little research has been conducted regarding the effects of rank and academic field on faculty attitudes in Saudi Arabian institutions. The author used a mail survey and collected 518 useable responses from a total of 710 questionnaires distributed. Factor analysis, MANCOVA, MANOVA, and ANOVA were the statistical methods employed in data analysis. Five attitudes were identified as a result of factor analysis: (a) attitudes toward teaching; (b) attitudes toward research; (c) mission; (d) promotion; and (e) interest. Results indicated that there was a significant difference between faculty and administrators regarding teaching and resea4rch. Administrators showed stronger attitudes toward teaching than faculty at all three universities. There were also significant differences regarding these attitudes in terms of rank, academic field, and university. Full professors had the strongest attitude toward a research emphasis compared to assistant professors. Assistant professors had the strongest teaching orientation. In addition, faculty members in the humanities had stronger teaching orientations preferences than did those in the natural and social sciences. Regarding the universities, faculty members at IU had the strongest teaching orientation preferences, whereas faculty members at KSU had the strongest research orientation preferences. > more info \| Use restricted to UNT community

	The nature of the impact of a reading tutoring program on participating students in the classroom: A qualitative study Date: 2000-08 Creator: Arrowood, Dana R. Description: The purpose of this qualitative multi-case study was to explore the nature of the impact that a tutoring program, which featured preservice teachers as tutors, had on participating fifth grade at-risk students literacy behaviors in the classroom.The researcher served in the role of passive participant observer during the scheduled language arts period three days per week in the participating students classroom for a period of twenty-three weeks. Field notes were made in the classroom and coded, and audio tapes were recorded and transcribed of the tutoring sessions. Formal and informal interviews with the teacher, tutors, and participating students were conducted, transcribed, and coded. Lesson plans and reflections developed and written by the tutors were gathered and coded. Observations indicated that there were four types of reading required on a daily basis in the classroom. Assigned readings made by the teacher included narrative and expository texts. Pleasure readings were materials chosen by the students, but at certain times were teacher initiated and at other times, student initiated. The four types of reading found in the classroom were mirrored by the tutoring sessions. Students observed in the classroom could be divided into two types and four categories. Those with positive attitudes were called eager readers. Eager readers were made up of good readers and struggling readers, who lacked some of the reading skills possessed by good readers. Reluctant readers were the second type and had either ambiguous or explicitly negative attitudes toward reading. The type of reader, together with the type of reading required, determined the success of the tutoring sessions. The results of the data analysis show that student motivation toward reading was a key factor in determining the success of the tutoring program. Two of the three student participants in the study reported learning skills in the tutoring program that they used in other contexts. > more info

	The developmental stages of concern of teachers toward the implementation of the Information Technology curriculum in Kuwait Date: 2000-08 Creator: Alshammari, Bandar S. Description: Change is best carried out by individual teachers, and, thus, identifying and resolving teachers concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis of the first highest and second highest concerns among teachers revealed the development of three patterns of concerns: self concerns, mixed concerns, and impact concerns. Results indicated that the majority of teachers were at the mixed-concern level. With more years of experience, teachers concerns shifted from self to task and finally to impact concerns. The results of concern analysis are consistent with Fullers theory of concern development. MANOVA revealed significant differences in means between females and males at management and refocusing stages. Females had higher concerns about management; males had higher refocusing concern. However, no significant relationship was found between experience and the reported stages of concern. For successful implementation, the concerns of teachers must be resolved. The CBAM including the SoCQ is recommended to KISITP coordinators as a diagnostic tool to facilitate change and to provide appropriate staff development. Suggestions were made for future research to continue validation of the SoCQ in Arabic cultures. > more info

	Curriculum analysis in teacher preparation programs at the college of basic education in Kuwait Date: 2000-08 Creator: Bufarsan, Fawzi A. Description: Preparing quality teachers is a continuing issue and concern in discussions about the future of schools in many countries. This study described and compared the stated goals and perceived outcomes of teacher preparation programs at the College of Basic Education (CBE) in Kuwait. This information will assist educational decision makers in Kuwait to align teacher preparation at the CBE and decide what is needed to make the programs more effective. The study assessed the perceptions of knowledge, skills, and attitudes of student teachers, new teachers, and instructors toward the existing program at the CBE in Kuwait. The discussion of teacher preparation in Kuwait was used to set a cultural and historical context. The literature reviewed recommendations from the United States to develop a framework of five common standards for analyzing the teacher preparation curriculum: content knowledge, instruction, diversity, professional development, and field work. In addition, research and evaluation of teacher education programs were reviewed for perceptions of student teachers and new teachers about their preparation and for methodology. Document analysis techniques were used with current documents from four major teacher preparation programs in the CBE. Five standards from U.S. recommendations were also found in the CBE curriculum. However, the analysis suggested that the curriculum in Kuwait might increase attention to professional attitudes and use of new technologies to prepare teachers. A three-part questionnaire was developed based upon the questionnaires of Van Zandt, Smith, and Zelazek et al. The questionnaire was translated into the Arabic language, and 280 responses to the survey instrument were analyzed. Perceptions of pre-service teachers, new teachers, and instructors toward the existing curriculum at the CBE in Kuwait were positive (3.3 and higher on 5-point scale) toward preparation of teachers knowledge, skills, and attitudes. However, a significant contrast was found between groups in perceptions of knowledge and skills. Pre-service teachers were more positive than first-year teachers or college instructors in their perceptions. No significant differences were found in attitudes. Recommendations included a suggestion to the faculty at CBE for continuing the model of curriculum analysis from this study to evaluate and address possible improvements in the teacher preparation program, such as use of technology and more attention to professional attitudes. Replication of the study was also suggested for other colleges of education in the Middle East. > more info \| Use restricted to UNT community

	The Effects of Parenting Stress and Academic Self-Concept on Reading Ability in a Clinic Referral Sample Date: 2001-05 Creator: Maldonado, Michele L. Description: This study investigated the relationships among the variables of parenting stress, academic self-concept, and reading ability. The purpose of this study was to determine whether parenting stress and academic self-concept contributed to the child's reading ability. Two hypotheses were investigated in an effort to accomplish this purpose. The subjects used in this study were forty-nine children and their primary caretakers referred to The Child and Family Resource Center, The University of North Texas, Denton, Texas, during the academic years of 1994 through 1999. Subjects ranged in age from seven to eighteen years of age. Academically, the subjects ranged from first graders through eleventh graders. All subjects lived in and attended schools in Denton County or neighboring counties. Parental employment ranged from unskilled laborers to medical doctors. The participating families included biological, step, adoptive, single, and divorced families. Abidin's Parenting Stress Index was used to measure parental stress experienced by the primary caretaker. The Intellectual and School Status cluster of the Piers-Harris Children's Self-Concept Scale was used to measure the child's academic self-concept and the Woodcock Reading Mastery Test-Revised provided a measure of the child's reading ability. Test scores were obtained following a review of The Child and Family Resource Center's documented files. Multiple regression statistics revealed no significant relationship between neither parenting stress and the child's reading ability nor the child's academic self-concept and reading ability. Standardized beta coefficients and bivariate correlation results indicated a relationship between academic self-concept and reading ability. Additional research is recommended for future research that encompasses a larger and more diverse sample. > more info \| Use restricted to UNT community

	An analysis of sales people's perceptions of performance appraisal criteria at a telecommunications corporation. Date: 2001-12 Creator: Harris, Ellen L. Description: The purpose of this study was to identify and analyze sales people's perceptions of performance appraisal criteria in a telecommunications corporation. The study was prompted by the perceived disillusionment of the sales people with the current performance appraisal criteria. The perceptions of 67 sales people were assessed using a questionnaire developed by the researcher. One-way analysis of variance procedures (ANOVA) were used to determine if there were statistically significant differences in premise and telemarketing sales people's perceptions of performance appraisal criteria. Findings indicated that there were no statistically significant difference in premise and telemarketing sales people's perceptions of the 38 performance appraisal criteria statements. Findings did not indicate a statistically significant difference in premise and telemarketing sales people's perceptions of the performance criteria statements, the attitude or satisfaction statements, and the peripheral issue statements. Based on this study, the sales people appear to have clear perceptions of the performance appraisal criteria. > more info

	A content analysis of reading software commercially available for Pre-K to 3rd grade children. Date: 2002-05 Creator: Nakjan, Sutat Description: The purpose of this qualitative study was to investigate the content and characteristics of the currently available commercial reading software for Pre-K through third grade children. The design of the study was a content analysis. Based on the evaluation rubric established by the researcher, ten commercial reading software were selected to be analyzed. By reviewing and transcribing, the data were obtained, and then coded, categorized, and interpreted. The findings from the analysis revealed that all reading software programs offered exercised for practicing basic phonics skills; the alphabetic principle, letter-sound association, word knowledge, sentence building, and reading comprehension. Depending on the software developers, phonics-based practice was presented in two ways; separate skill-based practice emphasis and storybook-reading emphasis. All software programs utilized drill-and-practice, direct instruction and mastery learning methods and utilized gaming strategies to motivate and engage the learners. Multimedia technology was used to make the software more appealing. All reading software programs were developed on the perspectives that view learning to read as the continuum of a child's oral language development and background experience about words. It is recommended that parents and teachers review and select the software based on reliable information sources, use the software as supplementary practice based on the learning objectives identified and individual student needs. > more info

	Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology. Date: 2003-05 Creator: Bray, Kaye Evitt Description: Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted that refereed journals were rated higher than nonrefereed journals for the Academic Prestige criterion. Survey respondents indicated that individual journals were not valued for the same reasons. This finding implies that the formation of any equitable measure for determining the value of faculty members' journal article publications would be best if based on definable criteria determined by colleagues. Lists of valued journals for each area of faculty assessment would provide standards of excellence both inside and outside the E/IT field for those who serve on tenure and promotion committees in educational institutions. > more info

	Examining the nature of interactions which facilitate learning and impact reading achievement during a reading apprenticeship: A case study of at-risk adolescent readers Date: 1999-12 Creator: Arthur, Mary L. Description: The purpose of this qualitative case study was to explore the interactions that take place during a reading apprenticeship which facilitate the learning of reading strategies by adolescent students who are at the middle school level and are still at-risk for reading failure and to investigate how a reading apprenticeship affects reading achievement in the areas of fluency, vocabulary development, comprehension, and the self-perception of the reader. The case study was descriptive and interpretive in nature, and examined two students, each of whom was part of a one-to-one reading apprenticeship. The researcher served as participant observer in both cases and was the teacher in each of the one-to-one reading apprenticeships. The primary data set was qualitative in nature, and elements of quantitative data were also considered. Sessions included pretesting and posttesting using the Classroom Assessment of Reading Processes (Swearingen & Allen, 1997), reading from narrative or expository books, working with words, writing, and dialoguing about the reading. Reading strategies were directly taught, modeled, and reinforced by the teacher/researcher with the goal of the students internalizing the strategies and improving their reading in the areas of fluency, vocabulary development, and comprehension, as well as improving their attitudes toward reading and their self-perception about their reading ability. This study described a reading apprenticeship which positively impacted reading achievement for two students in the areas of fluency, comprehension, and vocabulary development, as well as influencing their motivation for reading and their self-perceptions as readers. The environment of the reading apprenticeship, the dialogue that occurred throughout the reading apprenticeship, and strategy instruction, modeling, and reinforcement were found to be factors and interactions which facilitated learning during this intervention. > more info
