Equivalency of paper-pencil tests and computer-administered tests.

Access: Use of this item is restricted to the UNT Community
Are computer-administered versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that have caused differences when not controlled. To prove equivalency between test modes, scores have to have similar means, dispersions, and shapes; the ranked-order of the scores must also be similar. Four tests were given over the course of a 16-week semester. The sample was divided, half taking paper-pencil tests and half taking the same test administered by a computer. The mode of administration was switched with each test administration. The analysis showed that, when the intervening variables were controlled, the two modes of administration were equivalent. The analysis used a 2x4 ANOVA, which showed no difference between test modes, but showed that each test administration was significantly different. The Levene statistic was used to test whether dispersions were equivalent and confidence intervals were established to test the kurtosis and skewness statistics. Finally, each of the test scores were transformed into their Normal Curve Equivalents so that Pearson's coefficient could be used to determine the equivalency of the …

The Effects of Career Group Counseling on the Self-Concept of At-Risk High School Students as Measured by the Piers-Harris Children's Self-Concept Scale (open access)

The Effects of Career Group Counseling on the Self-Concept of At-Risk High School Students as Measured by the Piers-Harris Children's Self-Concept Scale

The purpose of this study was to determine the effectiveness of career group counseling in raising the self-concept of at-risk high school students. The following subgroups were represented in the sample: male and female students, white and non-white ethnic groups, and students from sophomore, junior, and senior classifications. Two groups of students in the Lewisville Independent School District meeting the criteria for at-risk as defined by House Bill 1010 were administered a pretest and posttest using the Piers-Harris Children's Self-Concept Scale. The experimental group was from the Lewisville Learning Center. The control group was students enrolled in the Coordinated Vocational Academic Education (CVAE) classes at Lewisville High School. A treatment sample of 25 students received career group counseling. A nontreatment sample of 25 students did not receive any group counseling. The t-test for independent samples was used to analyze the data. The pretests for the experimental and control groups showed no significant difference at the .05 level. The treatment sample received 30 hours of group counseling in the Fall semester of 1994. At the end of 30 hours of counseling a posttest was administered to the treatment sample and to the control sample. The t-test for independent samples was used …

Enhancing skill maintenance through relapse prevention strategies: a comparison of two models. (open access)

Enhancing skill maintenance through relapse prevention strategies: a comparison of two models.

In a quasi-experimental field study, two posttraining interventions composed of relapse prevention (RP) strategies were compared and tested for the effects on participant transfer outcomes. Participant retention of training content, skill maintenance, use of relapse prevention strategies, and self-efficacy served as the dependent variables. Self-efficacy was also tested as a mediator between the experimental treatment levels and both participant skill maintenance and participant use of RP strategies. Participants (n = 39) included managers, directors, and supervisors from various departments within a multi-national telecommunications organization located in a large southern city. After participating in a four-hour leadership development training, two of the three groups participated in a 30-40 minute training where they received one of two RP interventions. One intervention included the steps of (1) identifying potential obstacles to positive training transfer, (2) predicting the first lapse to pretraining behavior, and (3) applying relevant coping strategies to thwart a lapse. The alternative RP intervention included the same steps in addition to a goal setting step. Descriminant descriptive analysis was used to test for group differences across the response variables and to identify on which variables the groups differed. Three separate regression equations were used to test for the mediating relationship of …

Visual Cueing: Investigating the Effects of Text Annotation on Student Retention Rates

This Study examines the grades of students using study skill methods and those who do not. The experiment consists of giving the treatment group the opportunity to use well- known study techniques. The Control group could only read the material. Both groups were given ten minutes to read a pre-selected text. The text consisted of an 1,807 word lesson on the, "Technical Training Management System." Each group was given five minutes to take a twenty item quiz. Fifty-five students in the control group were limited to only reading the material. Fifty-six students in the treatment group could choose between highlighting, note-taking, and underlining. The results of the test scores were compared using a t - test for dependent samples. One week later, the same students in each group were re-tested, using the same quiz they had taken earlier.

Reliability of Authentic Assessment in Fourth-Grade Narrative and Descriptive Written Language for Students with and without Learning Disabilities

The purpose of this study was to determine reliability estimates of authentic assessment for fourth-grade narrative and descriptive writing samples for students with and without learning disabilities. Three types of reliability estimates were established: (a) inter-rater, (b) score stability, and (c) alternate-form. The research design involved 40 teachers, trained in holistic scoring by Education Service Centers 10 and 11 in Dallas and Fort Worth, Texas, who scored 16 writing samples. Approximately 2 weeks later the teachers rescored 8 of the same writing samples. In addition to scoring the writing samples, the teachers also completed a demographic questionnaire. The writing samples, which consisted of eight narrative and eight descriptive writings, were selected based upon teachers' holistic scores and scores from 1993 writing sample of the Texas Assessment of Academic Skills. Based upon these scores, two narrative and descriptive writings of above-average, average, and below-average writings were selected. In addition, two narrative and descriptive writing samples of students with learning disabilities in written language were selected.

Students' Criteria for Course Selection: Towards a Metadata Standard for Distributed Higher Education (open access)

Students' Criteria for Course Selection: Towards a Metadata Standard for Distributed Higher Education

By 2007, one half of higher education students are expected to enroll in distributed learning courses. Higher education institutions need to attract students searching the Internet for courses and need to provide students with enough information to select courses. Internet resource discovery tools are readily available, however, users have difficulty selecting relevant resources. In part this is due to the lack of a standard for representation of Internet resources. An emerging solution is metadata. In the educational domain, the IEEE Learning Technology Standards Committee (LTSC) has specified a Learning Object Metadata (LOM) standard. This exploratory study (a) determined criteria students think are important for selecting higher education courses, (b) discovered relationships between these criteria and students' demographic characteristics, educational status, and Internet experience, and (c) evaluated these criteria vis-à-vis the IEEE LTSC LOM standard. Web-based questionnaires (N=209) measured (a) the criteria students think are important in the selection of higher education courses and (b) three factors that might influence students' selections. Respondents were principally female (66%), employed full time (57%), and located in the U.S. (89%). The chi square goodness-of-fit test determined 40 criteria students think are important and exploratory factor analysis determined five common factors among the top 21 …

Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.

Access: Use of this item is restricted to the UNT Community
Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a …

An investigation of the use of instructional simulations in the classroom as a methodology for promoting transfer, engagement and motivation. (open access)

An investigation of the use of instructional simulations in the classroom as a methodology for promoting transfer, engagement and motivation.

Innovative educators seek technologies to facilitate or enhance the learning experience while taking nothing away from the message of instruction. Simulations have been shown to meet this requirement. While simulations cannot replace the teacher or the message of instruction, they can provide a deeper and more cognitively engaging learning experience. Classroom use of simulations has been ongoing since the 1960's. However, substantive research on their efficacy remains limited. What research has been conducted indicates that simulations possess great potential as aids to instruction. The author of this dissertation pursued this question focusing on whether simulations contribute to instruction by facilitating transfer, improved motivation and increased engagement. This dissertation documents a study in which instructional simulations were used in undergraduate science courses to promote engagement, transfer and knowledge-seeking behavior. The study took place at Midwestern State University (MSU), a public university located in north-central Texas with a student population of approximately 5,500. The study ran during the fall 2006 and spring 2007 terms. Samples consisted of students enrolled in GNSC 1104 Life / Earth Science during the fall term and GNSC 1204 Physical Science during the spring term. Both courses were offered through the Department of Science and Mathematics at MSU. …

The Texas Assessment of Academic Skills (TAAS) Test Scores as Predictors of Academic Success of First-Year Clarendon College Students

The problem in this study was to determine the relationship between the scores on the three parts (reading, writing, and mathematics) of the Texas Assessment of Academic Skills Test (TAAS) and the academic success of first-year students at Clarendon College, Clarendon, Texas. High school grade-point average and gender were also included in the study. The purpose of the study was to develop an equation to predict first-year college grade-point average at Clarendon College . The predictor variables were the three parts of the TAAS Test (reading, writing, and mathematics) , high school grade-point average, and gender. The equation was developed through multiple correlation/multiple regression multivariate procedures. All statistical analyses were calculated through sub-programs of the Statistical Package for the Social Sciences (SPSS). The study was limited to using only 1992/1993 Texas high school graduates who had entered Clarendon College in the fall semesters of 1992 and 1993 directly following high school graduation. A search of Clarendon College records produced 115 students from these groups who fully met all standards defined for the study. Two predictor equations were developed. One developed through a simple regression command included all five predictor variables. The second equation was produced through a stepwise procedure. This …

A study of the relationship between work experience and occupational work ethic characteristics of baccalaureate nursing students. (open access)

A study of the relationship between work experience and occupational work ethic characteristics of baccalaureate nursing students.

The primary purpose of this study was to test the theory of experiential learning by measuring to what extent work experience predicts the work ethic characteristics of students in baccalaureate nursing programs at three regional universities in Texas, including Midwestern State University in Wichita Falls, Tarleton State University in Stephenville, and West Texas A&M University in Canyon. Work experience is the amount full-time or part-time on-the-job experience. Work ethic attributes are referred to as considerate, ambitious, dependable, and cooperative. Results generated in this study failed to reject the null hypotheses, which means that work experience, does not provide evidence of the ability to predict the development of work ethic characteristics in baccalaureate nursing students who participated in this research study. Knowledge generated in this study provided alternative directions for future research with respect to the relationship between work experiences and work ethic characteristics in nursing students. Such research may be useful to nursing educators and trainers in the design and delivery phases of the educational process for nurses.

An Investigation of the Impact of Technology Expenditures on Student Achievement in Texas Districts

The purpose of this study was to explore the relationship between money spent on technology hardware, software, and training on district-wide achievement as measured by Texas standardized achievement tests, the Scholastic Aptitude Test (SAT), and the American College Test (ACT). A series of studies were carried out to develop a model of the relationship between Texas district TAKS, TAAS, ACT, and SAT scores for all subjects and district expenditures on technology hardware, technology software, and technology training. The findings of this study showed that although the mixture of uneven distribution of training, incentives, and equipment in these Texas districts clouds the issue of effective integration as it does for all districts (Anderson & Becker, 1998), and the mean level of per pupil technology expenditure for participating districts is of an amount ($192 per student) deemed unlikely to have substantial impact on student outcomes (Anderson & Becker, 1998), there are strong positive links between levels of expenditure and student achievement on the Texas Assessment of Knowledge and Skills and the American College Test that indicate that establishing guidelines for levels of expenditure, schedules of acquisition of materials and equipment, and timeframes for training and implementation may be vital to the success …

Effect of Individualized Curricular Accommodations, Incorporating Student Interest and the Impact on the Motivation and Occurrence/ Nonoccurrence of Disruptive Behavior Displayed By Students with Emotional/behavioral Disorders. (open access)

Effect of Individualized Curricular Accommodations, Incorporating Student Interest and the Impact on the Motivation and Occurrence/ Nonoccurrence of Disruptive Behavior Displayed By Students with Emotional/behavioral Disorders.

As a result of the reauthorization of the Individuals with Disabilities Education Act of 1997, schools must now consider positive behavioral interventions and strategies to address problem behavior of students with Emotional/Behavioral Disorders (E/BD). Given the poor behavioral, academic, and social outcomes for these students, there is a compelling need to identify effective, proactive interventions. Current literature has well established the ineffectiveness of traditional, punitive, and consequence-laden strategies to deal with behaviors. Research has shown the manipulation of antecedent stimuli, in the form of curricular adaptations, can provide a positive, proactive means of managing behavior. Specifically, curriculum modifications, based on student interest, are proposed as a positive, proactive strategy used to manipulate antecedent stimuli to improve the behavior of students with E/BD. The purpose of this study was to investigate the manipulation of antecedent stimuli through the implementation of individualized, curricular adaptations, based on student interest, to reduce the problem behavior of students exhibiting disruptive behaviors. A second purpose was to explore the effect of those adaptations on the behavior motivation of students with E/BD. In this study, curriculum modifications based on student interest were used to reduce disruptive behavior, increase desirable behavior, and effect change in the motivation for …

Six classes containing a total of 109 students took the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of signifi­cance of .01 was established. An independent samples t-test was conducted on the sample. Additionally, a one-way analysis of variance was performed between the classes administered the Block One Tests on computers. Several other frequencies and comparisons of Block One Test scores and other variables were accomplished. The variables examined included test versions, shifts, student age, student source, and education levels. The study found no significant difference between test administration modes.

The Effects of Team Dynamics Training on Conceptual Data Modeling Task Performance

Database modeling is a complex conceptual topic often taught through the use of project-based teams. One of the problems with the use of project-based teams in university courses is the determination of whether this is the most effective use of instructor and student time involvement and effort level. Therefore, this study investigated the impact of providing team dynamics training prior to the commencement of short-duration project-based team conceptual data modeling projects on individual data modeling task performance (DMTP) outcomes and team cohesiveness. The literature review encompassed conceptual data design modeling, the use of a project-based team approach, team dynamics and cohesion, self-efficacy, gender, and diversity. The research population consisted of 75 university students at a North American University (Canadian) pursuing a business program requiring an information systems course in which database design components are taught. Analysis of the collected data revealed that there was a statistically significant inverse relationship found between the provision of team dynamics training and individual DMTP. However, no statistically significant relationship was found between team dynamics training and team cohesion. Therefore, this study calls into question the value of team dynamics training on learning outcomes in the case of very short duration project-based teams involved in …

Levels of resourcefulness and motivation as they relate to sales force success: An examination of correlates using the hope theory.

This study sought to determine whether a relationship existed between individual salesperson's levels of goal-directed cognition and motivation and their professional success as determined by the percentage of sales goals achieved. Salespersons represented two companies with national sales forces: one from the financial services industry and one from the apparel manufacturing industry. Both groups of salespeople were responsible for complex selling tasks. The skill sets for these professionals included high levels of communication skills, extensive product knowledge, and competitive market knowledge. Survey research, both paper and pencil and online, was conducted using the Hope Scale developed by C. R. Snyder and associates (1991). Hope is defined as a two-dimensional construct of goal-directed thinking: resourcefulness, thoughtful planning to overcome obstacles to goals, and motivation, cognition to sustain momentum toward goal achievement. Theoretically, upon assessing salespersons' Hope scores, organizations would be better prepared to assist those with low Hope Scale Scores (HSS) in one of the two areas. Those with low resourcefulness scores could be trained in cognitive techniques to overcome obstacles to goal achievement. Those with low motivational scores would be identified for further analysis, from a developmental perspective, to better determine what personally initiates and sustains motivation to attain their …

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students.

Applying Cognitive Load Theory to the Design of Online Learning.

The purpose of the study was to investigate the application of cognitive load theory to the design of online instruction. Students in three different courses (N = 146) were measured on both learning performance and perceptions of mental effort to see if there were any statistically significant differences. The study utilized a quasi-experimental posttest-only control group design contrasting modified and unmodified instructional lessons. Both groups were given a posttest to measure knowledge gained from the lesson (cognitive domain of learning) and perceptions of mental effort involved. Independent samples t-tests were used to compare the mean performance scores of the treatment groups (i.e. the sections using redesigned materials) versus the control groups for all three courses. Cohen's d was also computed to determine effect size. Mental effort scores were similarly compared for each group on the overall cognitive load score, for a total of six data points in the study. Of the four hypotheses examined, three (H1, H2, H4) found no statistically significant difference between the experimental and control groups. Negative significance was found between the experimental and control group on the effect of modality (H3). On measures of cognitive load, no statistically significant differences were found.

Detecting the Presence of Disease by Unifying Two Methods of Remote Sensing.

There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types.
