The purpose of this study is to use Dimension Authoring Language (DAL) to write a Computer-Based Education (CBE) program which can control the DECtalk device and to use GIGI. utility programs and graphics editors, to improve DAL graphic capability. CBE embodies the idea of using computers as a tool in teaching by computer. Also the CBE control programs can keep track of students' record in the instructor's area. This way, instructors can improve lecture materials according to those records. The first chapter explains. what CBE is and its applications in education. The second chapter explains how DAL works and how to solve some of the language's technical problems. The third chapter explains how DECtalk works and how we can control this device in DAL programs. Since pictures can improve CBE programs, the fourth chapter explains picture files and graphic editors. Some problems related to DAL, DECtalk, and picture files are solved in this paper. However, there are several problems which still remain unsolved.Ball State UniversityMuncie, IN 47306

This dissertation is based on results from an intervention study targeting working memory training. A group of 46 boys and 11 girls (aged 10.7) that were attending special units in 16 regular schools participated in the study. The treatment group (n = 42) trained at school every day for 30-40 minutes with an interactive computer program (Cogmed training) for five weeks. The performances of the treatment group on reading related measures and basic number skills are compared to those of a group of students (n =15) that were attending similar special units and received only ordinary special educational instruction. Working memory measures and non-verbal problem solving were compared to students (n = 25) in a control group from a previous study. In Study I, it was found that reading comprehension and working memory measures correlated and improved at post-tests (T2, T3) for the treatment group to a larger extent than for the comparison group. In Study II, it was found that working memory measures and basic number skills were highly related. The performance of the boys in the treatment group improved more than that of the boys in the comparison group on basic number test at both post-tests. In Study III, basic skills assessed three years later (T4) are reported. The treatment group achieved higher scores in reading comprehension compared to pre-tests and compared to the control group. The treatment group seems to have gained from the cognitive training of working memory with the computer assisted program directly after training, after seven months and at the three year follow-up. The gains were observed on visuo-spatial working memory measure (T2, T3), reading comprehension and on basic number skills in boys (T2, T3, T4). The possible mechanisms that may be involved in and may explain the observed improvements of performances are discussed: executive function, attention, memory, motivation, emotions. The study has some methodological limitations and more research is needed to substantiate the efficacy of the program. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Submitted.</p>

The purposes of this study was to investigate seventh-grade students&rsquo / misconceptions related to forming and solving equations and examine the role of technology use in preventing and remedying these misconceptions. A group of 18 seventh grade students was given a diagnostic test before they started the equations unit to determine their misconceptions related to the topic. Students studied equations for 6 weeks and half of the instruction took place in the computer lab where they used various electronic manipulative and activities on the computer. The students were given another diagnostic test at the end of the instruction. After a month, they took another diagnostic test for the third time. The diagnostic tests were equivalent to each other in terms of item structures and contents. The effect of technology use in changing students&rsquo / performances on the diagnostic tests was determined by repeated-measures ANOVA. Furthermore, changes in students&rsquo / misconceptions were also analyzed qualitatively. According to the results, no significant effect of technology use on preventing and remedying misconceptions was found. However, technology positively affected students&rsquo / feelings, thoughts and attitudes towards equations. Outcomes of this study have some implications for teachers, teacher educators, and curriculum writers as solving and forming equations is fundamental for learning algebra and a very significant strand of school mathematics.

Professional research project (Au.D.)--University of South Florida, 2002. / Title from PDF of title page. / Document formatted into pages; contains 35 pages. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: A need has been established for aural rehabilitation (AR) sessions throughout the years. The literature reviewed here demonstrates that new hearing aid users do benefit from a structured follow-up AR program. However, this need is often not met for a variety of patient and audiologist related factors. Therefore, an AR program that could be viewed at home has been suggested. I have developed a prototype for a CD-ROM based aural rehabilitation (AR) program. Included in the program are communication and speechreading strategies, which are the most prevalent materials in AR. The instructional and interaction portions of the prototype were created to be understood by the average person. The prototype includes the use of video, graphics, and audio to support the written information and to incorporate a sense of excitement into the CD-ROM based program. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
