Cognitive Science is interested in being able to develop methodologies for analyzing human learning and performance data. Intelligent tutoring systems need good cognitive models that can predict student performance. Cognitive models of human processing are also useful in tutoring because well-designed curriculums need to understand the common components of knowledge that students need to be able to employ. A common concern is being able to predict when transfer should happen. We describe a methodology first used by Koedinger that uses empirical data and cognitively principled task analysis to evaluate the fit of cognitive models. This methodology seems particularly useful when you are trying to find evidence for“hidden" knowledge components, which are hard to assess because they are confounded with accessing other knowledge components. We present this methodology as well as an illustration showing how we are trying to use this method to answer an important cognitive science issue.

Master of Arts / Department of Modern Languages / Earl Brown / This report studies ESL tutoring feedback to Chinese and Saudi students. The objective is to research the reasons of feedback differences and similarities, which include previous and current English learning styles, habits, purposes for receiving tutoring, and evaluations of tutors. Faced with L2 learners who come from different cultural backgrounds, it is helpful for instructors and tutors to know L2 students’ previous English learning experiences in their home countries so that instructors and tutors can adjust teaching or tutoring for each student. In addition, students who speak the same L1 have common problems of English learning due to their L1. In this way, ESL tutors not only tutor English skills, but also promote cultural awareness. Meanwhile, knowing students’ cultural background is necessary to give tutoring for each L2 learner. The present study aims to explore L2 learners’ feedback from previous and current English learning experiences and will help L2 instructors and tutors to know some basic knowledge about two different language groups.

Thesis (MPhil)--University of Stellenbosch, 2000. / ENGLISH ABSTRACT: Technikon Southern Africa defined its role as distance learning institution with the implementation of the Integrated Learner Centred Distance Learning (ILCDE) model. This model implied the establishment of regional offices as well as the implementation of a tutor system. The tutor system implied the appointment of tutors at the different regional offices. In an attempt to take the distance out of distance learning the following functions of tutors were identified: • Telephone tutoring • Conducting contact sessions • Assessing assignments The focal point of this study was tutor development within a flexible learning system as no structured learning programmes for tutors exist at TSA. The purpose was to investigate and analyse the learning needs of tutors in a flexible learning system. Various critical questions stimulated this study. However, the following three questions formed the basis of this study: • What is the role of training and development in the tutor system? • Do tutors have a need for continuing professional learning programmes? If so, what . should the nature of such learning programmes be? • What should the criteria be to evaluate and monitor the development oftutors? A qualitative research approach was followed and the data was obtained by means of interviews and participative observation sessions. The subjects of the study were the tutors of the Subject Group: Management Leadership: Policing appointed for the registration period May 1998 - May 1999. One of the conclusions of the study was that the following processes regarding the tutor system need attention: • Recruitment and selection • Interviewing and appointment • Job descriptions • Orientation, training and development programmes • Evaluation and monitoring programmes • Role clarification • Marketing strategy The following recommendations were formulated: • A guide for the recruitment and appointment processes of its tutors should be compiled. • An assessment of the support needs of learners should be performed. • Establishing a continuing professional learning unit should be considered. • A proposal for learning interventions for continuing professional learning should be developed. / AFRIKAANSE OPSOMMING: DIE ROL VAN TUTORONTWIKKELING IN 'N PLOOffiARE LEERSTELSEL Die Technikon Suider-Afrika het sy rol as afstandsonderriginstansie gedefinieer toe die Geïntegreerde Leergesentreerde Afstandsonderrigmodel (lLeD£) geïmplementeer is. Hierdie model het die daarstelling van streekkantore asook die implementering van 'n tutorstelsel veronderstel. Die tutorstelsel het die aanstelling van tutors by die onderskeie streekkantore tot gevolg gehad. Om die afstand uit afstandsonderrig te haal, is die volgende drie funksies van tutors geïdentifiseer: • Telefoonbegeleiding • Fasilitering van kontaksessies • Assessering van werkopdragte Die fokuspunt van hierdie studie was tutorontwikkeling binne 'n plooibare leerstelsel, aangesien geen gestruktureerde leerprogramme vir tutors by TSA bestaan nie. Die doel was om die leerbehoeftes van tutors in so 'n plooibare leerstelsel te ondersoek en te ontleed. Verskeie kritiese vrae het aanvanklik hierdie studie gestimuleer, maar die volgende drie vrae het die basis van die studie gevorm: • Wat is die rol van opleiding en ontwikkeling in die tutorstelsel? • Is daar 'n behoefte aan deurlopende professionele leerprogramme? Indien ja, wat behoort die aard van die programme te wees? • Wat behoort die kriteria te wees om die ontwikkeling van tutors te evalueer en te monitor? 'n Kwalitatiewe navorsingsbenadering IS gevolg en die data IS deur middel van onderhoudvoering en deelnemende waarnemingsessies ingesamel. Die tutors wat aangestel is vir die registrasietydperk Mei 1998 - Mei 1999, van die Vakgroep: Bestuursleierskap: Polisiëring is vir die studie gebruik. Een van die gevolgtrekkings van die studie IS dat die volgende prosesse lil die daarstelling van die tutorstelsel aandag vereis: • Werwing en keuring • Onderhoudvoering en aanstelling • Posbeskrywings • Oriënterings-, opleidings- en ontwikkelingsprogramme • Evaluerings- en moniteringsprogramme • Roluitklaring • Bemarking Die volgende aanbevelings is geformuleer: • 'n Handleiding vir die werwing en keuring van tutors behoort saamgestel te word. • 'n Behoeftebepaling van die ondersteuningsbehoeftes van die leerders behoort gedoen te word. • Die vestiging van 'n deurlopende professionele leereenheid behoort oorweeg te word. • 'n Voorstel vir leerintervensies vir personeelontwikkeling behoort ontwikkel te word.

The need to give educators the ability to enter a particular teaching strategy of their choice into an Intelligent Tutoring System (ITS) and have the ITS respond appropriately to each student has been stated by many researchers. For example, an educator could tell the ITS to keep students within a certain help level ratio (how much help they request), or to introduce a new topic in a particular manner and the ITS simply carries this out at each learning point of interest. Educators could then try new strategies, ones that unaided are impossible to try out in class (such as keeping a student within a help-seeking range) or difficult within an ITS (as the ITS would have to be specially programmed in that way). Current ITSs provide adaptivity to the student at the domain level but not necessarily at the pedagogical level. While a variety of pedagogical strategies have been implemented (e.g. apprenticeship, socratic, practice), there is no system that offers parts or all of these strategies with the ability to choose between them dynamically. In this project, we designed a new framework for an ITS to include multiple, potentially adaptable pedagogical strategies. This was done by breaking up the pedagogical module into separate components. The Pedagogical Strategy Set (PSS) contains all the strategies, written as constraints. The Pedagogical Student Model (PSM) keeps track of which pedagogical strategies were used by each student. Within the ITS, there is still a smaller, separate pedagogical module to deal with domain-specific strategies. The Pedagogical Control Centre (PCC) contains the logic of when and how to use the pedagogical strategies. It gathers its information from the other modules and uses decision logic to trigger strategies. We implemented and evaluated this framework within the context of SQL-Tutor and found that the framework could be used to enter pedagogical strategies, which in turn compared favourably to the original SQL-Tutor. This proof of concept opens up the possibility of the logic and algorithms that could be implemented (e.g. in the PCC) in future ITSs. The PSS is a separate module, written in a different language, independent of ITSs. This could lead to sharing of pedagogical strategies between tutors. Furthermore, students learn differently to each other; this framework allows them to do so.

The purpose of this study was to investigate the effectiveness of cross-age tutoring by high school students on the affective perception of fourth graders in the areas of self-concept, perception of self as a student, perception of self as a social studies student, and perception of self in the school environment. The tutoring was done in social studies--specifically in Arizona history--relating to the culture, history, and environment of the students' own surroundings. A rationale for the study was based on the social learning theory. High school students modeled behavior for the elementary students and reinforced positive learning experiences dealing with their own culture. This experience would enhance the elementary students feelings of self-worth, and improve their self-perception. The literature was reviewed from three aspects: cross-age tutoring, self-concept, and affective perception. Eight elementary classrooms, four experimental and four control, in four schools in the southwest part of Tucson, Arizona were involved in this one study. Nine hypotheses were tested dealing with self-concept and perception of self. Results of the study were assessed through the Piers-Harris Children's Self-Concept Scale pre- and post-measures, and the Affective Perception Inventory. An analysis of data was subjected to a two-factor analysis of variance using a hierarchical design. The primary aspect of this design is the assumption that an individual's score is partly influenced by the social unit of which the individual is a member. In all categories the treatment of cross-age tutoring had no effect on the experimental means. The hypotheses did not prove to be significant at the F = .05 level of significance. (A significant difference was found in the direction of the control group's mean score on the post self-concept scale.) It is the finding of this study that there were too many variables, other than the tutoring process, that could not be controlled. A further examination of the results shows that there were significant school within treatment effects, in the perception of self in the school environment, which indicates that the treatment interacted with classroom variables.

The goal of this study was to evaluate whether Electroencephalography (EEG) estimates of attention and cognitive workload captured as students solved math problems could be used to predict success or failure at solving the problems. Students solved a series of SAT math problems while wearing an EEG headset that generated estimates of sustained attention and cognitive workload each second. Students also reported on their level of frustration and the perceived difficulty of each problem. Results from a Support Vector Machine (SVM) training indicated that problem outcomes could be correctly predicted from the combination of attention and workload signals at rates better than chance. The EEG data was also correlated with students' self-report of problem difficulty. Findings suggest that relatively non-intrusive EEG technologies could be used to improve the efficacy of tutoring systems.

The aim of this PhD thesis is to develop a framework for adaptive intelligent tutoring systems (ITS) in the domain of Modern Standard Arabic language. This framework will comprise of a new approach to using a fuzzy inference mechanism and generic rules in guiding the learning process. In addition, the framework will demonstrate another contribution in which the system can be adapted to be used in the teaching of different languages. A prototype system will be developed to demonstrate these features. This system is targeted at adult English-speaking casual learners with no pre-knowledge of the Arabic language. It will consist of two parts: an ITS for learners to use and a teachers‘ tool for configuring and customising the teaching rules and artificial intelligence components among other configuration operations. The system also provides a diverse teaching-strategies‘ environment based on multiple instructional strategies. This approach is based on general rules that provide means to a reconfigurable prediction. The ITS determines the learner‘s learning characteristics using multiple fuzzy inferences. It has a reconfigurable design that can be altered by the teacher at runtime via a teacher-interface. A framework for an independent domain (i.e. pluggable-domain) for foreign language tutoring systems is introduced in this research. This approach allows the system to adapt to the teaching of a different language with little changes required. Such a feature has the advantages of reducing the time and cost required for building intelligent language tutoring systems. To evaluate the proposed system, two experiments are conducted with two versions of the software: the ITS and a cut down version with no artificial intelligence components. The learners used the ITS had shown an increase in scores between the post-test and the pre-test with learning gain of 35% compared to 25% of the learners from the cut down version.

Tutorial support has become more relevant in recent years because of its implications on the socio-emotional and academic performance of students. Consequently, many universities are implementing institutional plans designed to enable students to strengthen their skills and abilities. In that sense, the study seeks to examine the perception of a group of 30 inland students, between the ages of 15 and 18, with respect to the activities developed during the 2014-1 tutorial program. A qualitative phenomenological design was used, as well as focus groups and projective techniques for the data collection process. The results indicate that students view the tutorial program as a space for support and attention, which contributes to the college-life adjustment process; however, they indicate that it should be adapted to the group’s ever-changing needs. / El acompañamiento tutorial, en los últimos años, ha venido cobrando relevancia debido a la implicancia que tiene en el desempeño socioemocional y académico de los estudiantes, es por ello que muchas universidades diseñan planes institucionales que permiten a sus estudiantes fortalecer habilidades y capacidades. En ese sentido, el presente estudio pretende conocer cuáles son las percepciones que tiene un grupo de 30 estudiantes, entre 15 y 18 años, provenientes del interior del país, respecto a las actividades desarrolladas en el programa tutorial del semestre 2014-1. Se empleó un diseño cualitativo de tipo fenomenológico, y para la recolección de datos se emplearon grupos focales y técnicas proyectivas. Los resultados indican que el programa tutorial es concebido por los estudiantes como un espacio de apoyo, escucha que favorece al proceso de adaptación a la vida universitaria, aunque, también, señalan que éste debe ajustarse de acuerdo a las constantes necesidades del grupo.

M.Ed. / The adult in today's society, is increasingly aware of his/her shortcomings regarding existing training skills and knowledge structures, as well as the need to supplement or refresh in order to keep up with demands. Conventional training methods alone cannot supply in the demand for competent educators to train the increasing number of adult learners, with their unique needs and approach to learning. The purpose of the study is the design of a self-study module as a possible training method for adult educators, as it is regarded as a cost-effective method to develop these educators by means of distance education and due to its availability regardless of their socio-economic background of the prospective educators. A study of literature and descriptive research was conducted to determine the structure and requirements of a selfstudy module. Relevant models of training program design were also studied. The information obtained was used to develop a selfstudy module dealing with the designing of training programs for adult learners, based on the Wheeler/KrUger model (1979). The following issues were addressed in the selfstudy module: A situation analysis, the planning of learning experiences for these adult learners, the setting of goals and objectives, the selection of teaching and learning opportunities, the development of teaching strategies, and evaluation of the training program. The selfstudy module is preceded by a short pretest for the prospective adult ducator. Each topic is succeeded by a selftest to assist the adult educator in determining his/her progress. On completion of the module he/she should be equipped to design a training program for adult learners. Although the designed module has not been tested, the conclusion could be made that selfstudy modules as a teaching method could supply in the demand for educators of adults. Self study modules seem specially appropriate in the South African setting with its geographically scattered society and varying academic and economic backgrounds.
