This thesis is concerned with the principled design of a computational environment which depicts an animated view of program execution for novice programmers. We assert that a principled animated view of program execution should benefit novice programmers by: (i) helping students conceptualize what is happening when programs are executed; (ii) simplifying debugging through the presentation of bugs in a manner which the novice will understand; (iii) reducing program development time. The design is based on principles which have been extracted from three areas: (i) the problems that novices encounter when learning a programming language; (ii) the general design principles for computer systems; and (iii) systems which present a view of program execution. The design principles have been embodied in three 'canned stepper displays for Prolog, Lisp and 6502 Assembler. These prototypes, called APT-0 (Animated Program Tracer), demonstrate that the design principles can be broadly applied to procedural and declarative; low and high level languages. Protocol data was collected from subjects using the prototypes in order to check the direction of the research and to suggest improvements in the design. These improvements have been incorporated in a real implementation of APT for Prolog. This principled approach embodied by APT provides two important facilities which have previously not been available, firstly a means of demonstrating dynamic programming concepts such as variable binding, recursion, and backtracking, and secondly a debugging tool which allows novices to step through their own code watching the virtual machine in action. This moves towards simplifying the novice's debugging environment by supplying program execution information in a form that the novice can easily assimilate. An experiment into the misconceptions novices hold concerning the execution of Prolog programs shows that the order of database search, and the concepts of variable binding, unification and backtracking are poorly understood. A further experiment was conducted which looked at the effect that APT had on the ability of novice Prolog programmers to understand the execution of Prolog programs. This demonstrated that the performance of subjects significantly increased after being shown demonstrations of the execution of Prolog programs on APT, while the control group who saw no demonstration showed no improvement. The experimental evidence demonstrates the potential of APT, and the principled approach which it embodies, to communicate run-time information to novice programmers, increasing their understanding of the dynamic aspects of the Prolog interpreter. APT, uses an object centred representation, is built on top of a Prolog interpreter and environment, and is implemented in Common Lisp and Zeta Lisp and runs on the Symbolics 3600 range of machines.

Above-elbow myoprostheses aim to restore the functionality of amputated limbs and improve the quality of life of amputees. By using electromyography electrodes attached to the surface of the skin, amputees are able to control motors in myoprostheses by voluntarily contracting the muscles of their residual limb. An advance in myoelectric control called targeted muscle reinnervation (TMR) reinnervates severed nerves into healthy muscle tissue and increases the number of muscle sites available for use in control purposes. In order to improve rehabilitation after TMR surgery, an inexpensive myoelectric training tool has been developed in collaboration with the Glenrose Rehabilitation Hospital that can be used by TMR patients for biofeedback applications. The training tool consists of a robotic arm, signal acquisition hardware, controller software, and a graphical user interface. This dissertation describes the design and evaluation of the training tool and its use as a research platform for testing novel controllers.

Every published introductory psychology textbook includes boldfaced terms throughout the chapters. These boldfaced terms are theoretically included to help students learn the material. Are they really beneficial for student learning? An experimental/control group designed study was conducted to answer this question. Volunteers were provided with a chapter excerpt. The experimental group received the excerpt with no boldfaced terms included (the bold type had been removed), whereas the control group received the excerpt as it normally appeared in the textbook, boldfaced terms included. Both groups were quizzed using a 10-item multiple-choice quiz. Statistical analyses showed that those who studied the excerpt with boldfaced terms included scored significantly higher, F(1, 180) = 5.68; p = .02; partial ç2= .03, with an effect size of .32. This study and the resulting conclusions provide support for the inclusion of boldfaced terms in textbooks to aid student study and learning.

Software development is no longer a task limited to professionally trained computer programmers. Increasing support for software customization through scripting, the opening of application programmer interfaces on the Web, and a growing need for domain specific application support have all contributed to an increase in end-user programming. Unfortunately, learning to program remains a challenging task, and the majority of end-user programmers lack any formal education in software development. Instead, these users must piece together their understanding of programming through trial and error, examples found online, and help from peers and colleagues. While current approaches to address the difficulties facing end-user programmers seek to change the nature of the programming task, I argue that these challenges often mirror those faced by all novice programmers. Thus, pedagogical solutions must also be explored. This dissertation work investigates the challenges that end-user programmers face from a computer science education perspective. I have engaged in a cycle of learner-centered design to answer the high-level questions: What do users know; what might they need to know; how are they learning; and how might we help users discover and learn what they need or want to know? In so doing, I uniquely frame end-user programming challenges as issues related to knowledge and understanding about computer science. Rather than building new languages or programming tools, I address these difficulties through new types of instructional materials and opportunities for felicitous engagement with them. This work is contextualized within a specific domain of non-traditional programmers: graphic and web designers who write scripts as part of their careers. Through an in-depth, learner-centered investigation of this user population, this dissertation makes five specific contributions: (1) A detailed characterization of graphic and web design end-user programmers and their knowledge of fundamental computing concepts. (2) An analysis of the existing information space that graphic and web designers rely on for help. (3) The implementation of a novel case-based learning aid named ScriptABLE that is explicitly designed to leverage existing user practices while conveying conceptual knowledge about programming. (4) Initial confirmatory evidence supporting case-based learning aids for the informal computing education of web and graphic design end-user programmers. (5) An argument in support of the value of normative computing knowledge among informally trained programmers.

Title: The learning aids for educational therapy of dysortographia of primary school pupils pupils Thesis "The learning aids for educational therapy of dysortographia of primary school pupils" aims at assembling a list of method of reducing dysortographia - a specific grammar disability - and assessing their effectiveness for treating this disability. The theoretical part of the thesis covers terminology, symptoms and ethiology of specific learning disabilities. Next, the topic of specific learning disabilities is discussed in the context of primary school (ages 7 - 12). Diagnostics, methods of educational therapy and learning aids are described in relation to dysortographia. The reserch part of the thesis describes the methods used in special pedagogical intervention and, based on analysis of input and output diagnostics, assesses the effect of used methods on management of dysortographia in a chosen sample of pupils, compared to the control group which hasn't been treated with these methods.

I detta examensarbete utforskar jag hur en kan arbeta med en designprocess i möbler för en skolmiljö med ett bredare fokus än vad möblerna på marknaden är idag. Genom att utgå från barn i klassrummet med varierande behov, hoppas jag på att designa skolmöbler som passar fler individer. Med det har jag utgått i designprocessen med perspektivet och arbetsmetoden – Design for all och tagit fram en möbel som kan placeras in en skolmiljö i dagens klassrum. Min förhoppning är att kunna formge skolmöbler som inkluderar hjälpmedel som stimulerar och hjälper till i elevens arbete. Syftet med att fördjupa mig i ämnet skolmöbler är att jag vill fördjupa mig i skolans värld och lära känna miljöerna som möblerna sätts in i. Detta med en önskan att sedan i arbetslivet arbeta med att ta fram anpassade möbler. Arbetet inleds med en teoretisk undersökning där jag gör platsbesök på skolor, har samtal med pedagoger och med en fysioterapeut vid namn Ulrika Myhr som jag har samarbetat med samt dialog med handledare. Med ett valt fokus på mellanstadiet arbetar jag utifrån ett befintligt klassrum tillhörande en fyra bestående av två mentorer och 34 elever. Där har jag en dialog med eleverna och pedagogerna om hur de ser på och arbetar i sin miljö. Därefter gör jag egna analyser från de resultaten och gör ett förslag på möbler tänkta för det klassrum jag arbetat med. Därpå går jag över till en praktisk undersökning där jag har en kontinuerlig dialog om ergonomi med Ulrika Myhr samt jag testar hur ergonomi och design möts tillsammans i en form som till slut blir min design. Min slutsats visar på att det är svårt att få in alla funktioner i en möbel och tillgodose alla elever även ifall om man designar utifrån perspektivet design for all. Men däremot går det att designa för fler och för fler än vad det görs nu. Jag drar också slutsatsen att ha involverat eleverna själva i designprocessen har visat på att de har tydligt själva vet vad de vill ha och deras åsikter har gjort att mitt arbete har gett ett så gott resultat. / In this degree project, I explore how one can work with design processes in furniture for a school environment with a broader focus than the furniture on the market today. By focusing on children in a classroom, all with a broad spectrum of different needs, I hope to design school furniture that suits more individuals. I have started this particular design process with the perspective, and working method, of "design for all"; and produced a piece of furniture that can be placed in a school environment in today's classroom. My hope is to be able to design school furniture that includes features which can stimulate and assist the student's work. The further purpose of this project is that I want to immerse myself in the world of today's pupils, getting to know the environments that the furniture they use is placed in. My hope is that this will aid me in my further desire to then work on creating customized furniture in my professional working life. My working process begins with a theoretical investigation where I make on-site visits to schools, have conversations with educators and with a physiotherapist named Ulrika Myhr, with whom I have also collaborated, as well as dialogue with supervisors. With a chosen focus on the ages of 9-12, which constitutes the Swedish school system's later primary school years, I work on-site with access to a fourth-grade class and classroom, consisting of two mentors and 34 students. There, I have a dialogue with the students and teachers about how they view and use their working environment. I then make my own analyzes from those results which leads to a proposal for new furniture intended for the classroom I worked with. I then move on to a practical investigation where I have an on-going dialogue about ergonomics with Ulrika Myhr, and I test how ergonomics and design meet in the form that ultimately becomes my design. My conclusion shows that it is difficult to include all necessary functions in a piece of furniture while still satisfying the needs of all students, even if you design it from the perspective of "design for all". But on the other hand, it is possible to design for more people than is currently being done. I also conclude that having involved the students themselves in the design process has shown that they clearly know what they want, and their opinions have given the results of my work a greater legitimacy in its relevance.
