Title: DEVELOPMENT AND VALIDATION OF THE BEILE TEST OF INFORMATION LITERACY FOR EDUCATION (B-TILED).

Show moreFew constituencies exist where it is more important to produce information literate individuals than teacher candidates, yet rarely is it suggested that practitioners entering the field are adequately prepared to teach and model information literacy to their students. As a result, information literacy has been established as a key outcome by a number of teacher education accrediting bodies and professional associations. Corollary to this initiative is the effort to develop valid instruments that assess information literacy skills. Yet, at the time of this dissertation, no rigorously reviewed instruments were uncovered that measure the information literacy skills levels of teacher candidates. The study describes the development and validation of the Beile Test of Information Literacy for Education (B-TILED). Funded in part by the Institute for Library and Information Literacy Education and the Institute of Museum and Library Services, the study is part of a national initiative spear-headed by the Project for the Standardized Assessment of Information Literacy Skills (SAILS). Test content is based on nationally recognized standards from the International Society for Technology in Education and the Association of College and Research Libraries. Procedures designed to enhance the scale's validity were woven throughout its development. 172 teacher education students at a large, metropolitan university completed a protocol consisting of 22 test items and 13 demographic and self-percept items. This instrument can be used to inform curricular and instructional decisions and to provide evidence of institutional effectiveness for program reviews.

Title: IMPLEMENTATION AND TESTING OF A BLACKBOX AND A WHITEBOX FUZZER FOR FILE COMPRESSION ROUTINES.
Creator: Tobkin, Toby, Guha, Ratan, University of Central Florida
Abstract / Description: Fuzz testing is a software testing technique that has risen to prominence over the past two decades. The unifying feature of all fuzz testers (fuzzers) is their ability to somehow automatically produce random test cases for software. Fuzzers can generally be placed in one of two classes: black-box or white-box.

Show moreFuzz testing is a software testing technique that has risen to prominence over the past two decades. The unifying feature of all fuzz testers (fuzzers) is their ability to somehow automatically produce random test cases for software. Fuzzers can generally be placed in one of two classes: black-box or white-box. Blackbox fuzzers do not derive information from a program's source or binary in order to restrict the domain of their generated input while white-box fuzzers do. A tradeoff involved in the choice between blackbox and whitebox fuzzing is the rate at which inputs can be produced; since blackbox fuzzers need not do any "thinking" about the software under test to generate inputs, blackbox fuzzers can generate more inputs per unit time if all other factors are equal. The question of how blackbox and whitebox fuzzing should be used together for ideal economy of software testing has been posed and even speculated about, however, to my knowledge, no publically available study with the intent of characterizing an answer exists. The purpose of this thesis is to provide an initial exploration of the bug-finding characteristics of blackbox and whitebox fuzzers. A blackbox fuzzer is implemented and extended with a concolic execution program to make it whitebox. Both versions of the fuzzer are then used to run tests on some small programs and some parts of a file compression library.

Show moreIn Florida a number of highway bridges were retrofitted on their reinforced concrete (RC) girders with carbon-fiber reinforced polymers (CFRP) during the 1990's. Their conditions, after being in service for approximately 10 years, are of significant interest to the State's highway authority, as well as researchers in the region. This paper will evaluate if a load test on one of such bridges, which was retrofitted with CFRP at the girders in the splash-zone and thus was subjected to severe environmental conditions, is a feasible technique to evaluate the actual condition of the CFRP. A 3-dimensional Finite Element Model (FEM) was utilized to assess the load-deflection behavior of the bridge. An analytical study was used to evaluate the effective moment of inertia of the strengthened beams modeled on the FEM. The results indicate that the deflection change due to the amount of CFRP sheets assumed to be effective on the beam is insignificant. The paper also shows that it would not be feasible to estimate changes in the properties in the CFRP based only on deflection and strain measurements.

Show moreThis study measures the effectiveness of the National Computer Systems (NCS) Learn SuccessMaker Math Concepts and Skills computer program on standardized test scores at a middle school in east central Florida. The NCS Learn Company makes three claims for the SuccessMaker interactive computer program, Math Concepts and Skills (MCS): 1. Student Florida Comprehensive Assessment Test (FCAT) scores will improve from using the software 30 hours or more; 2. The increase in FCAT scores is directly related to the length of time the students' spend using the program; 3. The software package grading system is equivalent to the FCAT scoring. This study was designed to evaluate each claim. To test the first claim, the FCAT Norm Referenced Test (NRT) Mathematics scale scores of the 6th-grade middle school students were compared to the same students' previous FCAT scores. The scores were compared before and after they used the Math Concepts and Skills program. An independent t test was used to compare the scores. There was a statistically significant difference in scale scores when the students used the MCS program for 30 hours or more. Further investigation is needed to establish the causal effect for the observed differences. To test the second claim, the 6th- and 8th-grade students' time on task in the laboratory was compared to their change in FCAT scores. A Pearson correlation coefficient of 0.58 was found to exist for the complete 6th-grade data set and a 0.71 correlation for the 8th-grade group. To test the third claim, the MCS computer program grade equivalent scores were compared to the mathematics FCAT Level using the dependent t test to see if the two scores were equal. The analysis revealed that the difference in the two scores was statistically significant. Therefore the claim that the two scores are equivalent was not true for this data set. Recommendations were made for future studies to include qualitative data, a control group, and larger sample sizes. Studying the effect of the Math Concepts and Skills program on FCAT scores continues to be a project for investigation as implementation of the computer software is contingent on improving FCAT scores.

Building upon the conceptual framework, are constructs of school climate and assessment to develop themes such as leadership role, teacher role, district role, and coach's role as well as teacher practice, classroom assessment, standardized assessment, and the alignment of curriculum to standardized testing. In discovering the parallel between standardized testing and teacher practice, both qualitative and quantitative data were collected through research and observations, but more importantly through a survey and focus group. Over a two-semester period, it became evident that there was an eminent parallel between each the themes and constructs within the conceptual framework, ultimately answering the research question. Although the data fulfilled the research question of this study, future research would require a more in-depth, longitudinal study in order to suggest possible ideas for solutions.

Show moreABSTRACTWith the passing of the No Child Left Behind legislation (2001), individual states have been required to administer standardized tests to measure students' academic achievement in several academic areas, including reading comprehension. Many schools are using curriculum embedded reading comprehension tests to assess students' progress in achieving grade level expectations before the administration of state standardized test. This study used de-identified student data on curriculum embedded reading comprehension tests and the state standardized reading test, FCAT 2.0 to assess the correlation between a specific curriculum-based measure and the FCAT 2.0. The researcher used Pearson and Spearman Correlation to assess the predictive relationship of the curriculum-embedded reading tests and FCAT 2.0 reading. Strong correlations were found between the two assessments which educators may find useful when planning and differentiating reading comprehension instruction throughout the school year.

Show moreToday's focus on high-stakes standardized tests has had a massive impact on education throughout America, and standardized test preparation is one of the ugly, open secrets of education. Ever since 2001 when President Bush signed into law No Child Left Behind (NCLB), a bipartisan reauthorization of Johnson's landmark Elementary and Secondary Education Act of 1965, students have been bombarded with standardized tests from the earliest grades. Politicians believe these measures are the only way to remedy the perceived weaknesses in the education system because (")stringent accountability mandates… [provide] vital levers of change, inclusiveness, and transparency of results(") (Education Week, 2011, para. 15). Yet as time progresses, the quantity and importance of the exams increase to such proportions that, by the time students are in high school, their performance dictates whether they will graduate or attend college. While proponents of such exams say that they only test the skills that students ought to be learning anyway, the reality tends to be that teachers start to focus only on the specific questions the test will cover, and thereby lose the ability to provide full, comprehensive education. "Teaching to the test" is the much-maligned experience of most high schools. In order to combat the pressure students feel to perform and teachers feel to shortchange the learning experience, a (")Build Your Own Adventure(") manual designed around research-based principles demonstrated to improve student learning gains will allow students to focus on the key areas needed to improve test performance, demystify the test itself, and thus help students obtain score improvement. In so doing, students will not only perform better on standardized assessments, but ultimately be able to attend more elite colleges.

Show moreUniversity of Central Florida College of Engineering Thesis; The development of distributed applications has not progressed as rapidly as its enabling technologies. In part, this is due to the difficulty of reasoning about such complex systems. In contrast to sequential systems, parallel systems give rise to parallel events, and the resulting uncertainty of the observed order of these events. Loosely coupled distributed systems complicate this even further by introducing the element of multiple imperfect observers of these parallel events. The goal of this dissertation is to advance parallel and distributed systems development by producing a parameterized model that can be instantiated to reflect the computation and coordination properties of such systems. The result is a model called paraDOS that we show to be general enough to have instantiations of two very distinct distributed computation models, Actors and tuple space. We show how paraDOS allows us to use operational semantics to reason about computation when such reasoning must account for multiple, inconsistent and imperfect views. We then extend the paraDOS model with an abstraction to support composition of communicating computational systems. This extension gives us a tool to reason formally about heterogeneous systems, and about new distributed computing paradigms such as the multiple tuple spaces support seen in Sun's JavaSpaces and IBM's T Spaces.

The research aimed to determine the influence of tutoring participation for urban high school students.Participants included students enrolled in one urban high school who participated in the FCAT Reading and EOC assessments and is was identified if they participated in the school tutoring program or not.Quantitative results revealed the relationship between students' frequency of participation and performance outcomes on state assessments. Then, the relationship between achievement on state assessments for all students, students with disabilities, and English Learners who participated in after school tutoring and those who did not participate in after school tutoring were examined. Finally, the relations of frequency of participation in tutoring to corresponding final grades were evaluated. Participants included students enrolled in one urban high school who participated in the FCAT Reading and EOC assessments and it was identified if they participated in the after school tutoring program or not. Statistically significant differences in performance outcomes existed between tutored students in mathematics courses who participated in tutoring and those who did not. However, there was no statistically significant difference in performance outcomes with students in courses that were heavily based on reading as a result of their participation in tutoring. The students with disabilities subgroup as well as the English Learners subgroup both experienced statistically significant differences in reading scores as a result in tutoring participation. These same subgroups did not experience statistically significant difference on other assessments: Algebra 1 EOC, Geometry EOC, Biology EOC, and U.S. History EOC.Although this study identified relationships tutoring participation had with accountability measures achieved by students there is still much to be understood. The structure and approach to tutoring intervention programs should continue to be sought after in research in an effort to continue providing all students with opportunities for success on high stakes testing.

Show moreThe advance of technology is thought to help ease the myriad tasks that are usually involved in operating equipment. Training and testing in modern times have been replacing with simulation technologies that mimic the actual live operations and testing. Many successful stories of flight simulation come from military fighter aircraft and commercial pilot programs. The possibilities of safety in saving lives, economic incentive in reducing the operational cost and reducing the carbon footprint via simulation makes simulation worth looking into. These considerations quickly boosted the transfer from live training operations to virtual and simulation, as were easily adopted in the history of flight training and testing. Although, there has been a lack of application, the benefits of the computer based simulation as a modeling and simulation (M&S) tool can be applied to the commercial driver license (CDL) for the trucking industry. Nevertheless, this is an uphill battle to convince CDL administrators to integrate modern technology into the CDL program instead of using the traditional daily business of manual testing. This is because the cost of trucking industry live operations is still relatively affordable; individuals and companies are reluctant to adopt the use of the modeling and simulation driving or testing system. Fortunately, cost is not the only variable to consider for the training and testing administrators and their management. There is a need to expand the use of technology to support live operations. The safety of the student, trainer, and tester should be taken into account. The availability of training or testing scenarios is also an influencing factor. Ultimately, the most important factor is driving safety on the American road. The relationship of accidents with driver license fraud has led the Federal Department of Transportation to want to reduce fraud in third-party Commercial Driver License (CDL) administration. Although it is not a perfect solution that can fix all, the utilization of simulation technologies for driving assessment could be a solution to help reduce fraud if it is applied correctly. The Department of Transportation (DOT) authorized the statesÃ‚Â' independent authority to administrate the local CDL including the use of the Third-Party Tester (TPT). As a result, some criminal activities prompted the Federal investigation to recommend changes and to fund the states to take action to stay in compliance with the Federal regulation. This is the opportunity for the state CDL administrator to explore the use of M&S to support its mission. Recall, those arguments for the use of the M&S is the thought of safety in saving lives, economic incentive in reducing the operational cost, and reducing the carbon footprint via using simulation. This makes simulation a viable resource. This paper will report the research study of using the computer based testing modeling and simulation tools to replace or augment the current state examiner as means of assessing the CDL TPT proficiency in basic backing skills. This pilot study of this system has several aspects to address. The scenarios must be relevant to test the knowledge of the TPT by using closely comparable scenarios to the current manual testing method. The scenario-based simulation should incorporate randomness to provide a greater sense of reality. In addition, the reconfigurable built-in random behavior scenarios provide the administrator greater control of behaviors and allow the administrator to be able to select among the random scenarios. Finally, the paper will present the data sampling from relevant participants of the CDL TPT and methodology applied. The analysis of data presents in this research study will be valuable for the State and Federal CDL administrator to consider the pros and cons of applying or adding a computer based simulation to their current testing methodology.

Show moreThis applied dissertation paper introduced a program evaluation of a secure laptop-based testing (SLBT) program, which was implemented from 2009 to 2014 in an undergraduate nursing program at a private institution in the southeastern region of the United States (US). Computerized testing is an old topic in the educational research field, but the instructor-made, laptop-based secure testing that utilizes learning management systems (LMS) for undergraduate nursing programs is a fairly new topic in the US. Traditionally, testing has been administered with paper and pencil in the undergraduate nursing programs in the US for security reasons. Recently, with different robust LMSs, together with availability of affordable laptops, SLBT has become a reality on many campuses. The undergraduate nursing program at the Adventist University of Health Sciences (ADU) began to implement the SLBT program in 2009, which allowed students to use their newly purchased laptops to take secure quizzes and tests in their classrooms. After nearly five years' SLBT program implementation, a formative evaluation was conducted to seek constructive feedback from students, faculty, and technology support personnel to improve the program. Evaluation data show that, overall, students believed the SLBT program help them get hands-on experience of taking exams on the computer and get them prepared for their National Council Licensure Examination for Registered Nurses (NCLEX-RN) which is also computerized. Students, however, had a lot of concerns on laptop glitches and campus wireless network glitches they experienced during testing. Faculty and technology support personnel, on the other hand, were very satisfied with the SLBT program. Another goal of this evaluation study was to determine if students' first-time passing rate of NCLEX-RN has been improved significantly after the implementation of the SLBT program. NCLEX-RN first-time passing rate data were analyzed using the Chi-Square test and it revealed that there was no significant association between the two types of testing method (paper-and-pencil testing and the secure laptop-based testing) and whether or not students would pass NCLEX-RN the first time X2(1) = 3.53, p (>) .05. Based on the odds ratio, however, the odds of students passed NCLEX-RN the first time were 1.37 times higher if they were taught with the SLBT testing method than if taught with the traditional paper-and-pencil testing method in nursing school.

The first question asked if SJT response instructions (i.e., 'Should Do', 'Would Do') moderated the validity of an SJT in a maximum performance context. The second question asked what the upper-bound criterion-related validity coefficient is for SJTs in talent selection contexts in which typical performance is the criterion of interest. The third question asked whether the SJT used in the present study was fair for gender and ethnic-based subgroups according to Cleary's (1968) definition of test fairness. Participants were randomly assigned to complete an SJT with either 'Should Do' or 'Would Do' response instructions and their maximum decision making performance outcomes were captured during a moderate fidelity poker simulation. The findings of this study suggested knowledge, as measured by the SJT, interacted with response instructions when predicting aggregate and average performance outcomes such that the 'Should Do' SJT had stronger criterion-related validity coefficients than the 'Would Do' version. The findings also suggested the uncorrected upper-bound criterion-related validity coefficient for SJTs in selection contexts is at least moderate to strong (β = .478). Moreover, the SJT was fair according to Cleary's definition of test fairness. The implications of these findings are discussed.

Title: HIGH PRESSURE TESTING OF COMPOSITE SOLID ROCKET PROPELLANT MIXTURES: BURNER FACILITY CHARACTERIZATION.
Creator: Carro, Rodolphe, Petersen, Eric, University of Central Florida
Abstract / Description: Much Research on composite solid propellants has been performed over the past few decades and much progress has been made, yet many of the fundamental processes are still unknown, and the development of new propellants remains highly empirical. Ways to enhance the performance of solid propellants for rocket and other applications continue to be explored experimentally, including the effects of various additives and the impact of fuel and oxidizer particle sizes on burning behavior.

Show moreMuch Research on composite solid propellants has been performed over the past few decades and much progress has been made, yet many of the fundamental processes are still unknown, and the development of new propellants remains highly empirical. Ways to enhance the performance of solid propellants for rocket and other applications continue to be explored experimentally, including the effects of various additives and the impact of fuel and oxidizer particle sizes on burning behavior. One established method to measure the burning rate of composite propellant mixtures in a controlled laboratory setting is to use a constant-volume pressure vessel, or strand burner. To provide high-pressure burn rate data at pressures up to 360 atm, the authors have installed, characterized and improved a strand burner facility at the University of Central Florida. Details on the facility and its improvements, the measurement procedures, and the data reduction and interpretation are presented. Two common HTPB/AP propellant mixtures were tested in the original strand burner. The resulting burn rates were compared to data from the literature with good agreement, thus validating the facility and related test techniques, the data acquisition, data reduction and interpretation. After more than 380 successful recordings, an upgraded version of the strand burner, was added to the facility. The details of Strand Burner II, its improvements over Strand Burner I, and its characterization study are presented.
