Although the merits of practical work in physics are often questioned, it remains part of physics curricula world-wide. In distance education the incorporation of practical work into the curriculum is considerably complicated by the unique logistics of the setting and the high cost involved. The research reported in this thesis emanated from the need to improve the practical work module for first year physics at the University of South Africa, one of the largest distance education universities in the world. Specifically, the home-based component which, up to the commencement of the research had been entirely text-based, needed to be addressed. To this end it was necessary to identify a valid and attainable set of objectives and to determine the characteristics, abilities and needs of the students in the target group. A survey polling the viewpoints of South African physics lecturers and students about the objectives of practical work was conducted and an extensive student profile comprising a biographic, cognitive and affective component was compiled. Biographically, the target group is unique in the sense that it consists mainly of adult learners, a large percentage of whom study in a second language. The cognitive component of the profile covered aptitude, proficiency in English, mathematics and the integrated science process skills and level of cognitive development, all of which were investigated for possible influence on performance in practical work. On an affective level, students displayed a very positive attitude towards practical work, seated mainly in their need for concrete exploration of the theory. A practical work module structured around an experiential learning cycle adapted to the distance education environment was subsequently designed. The study material developed for the module comprised an interactive study guide on data processing and experimental procedure, a home experiment kit with accompanying workbook and a laboratory manual. From the pilot study forming part of the development process, it was found that students performed significantly better in an assignment based on home-experimentation than in any of the pen- and paper assignments preceding it. Based on the results of the pilot study, a full home experiment kit was designed, evaluated, refined and implemented. / Physics / D.Phil. (Physics)

An exploratory, descriptive design in the phenomenological approach was used to describe and explore how student tutors' experienced the process of evaluation of their clinical teaching in a specific distance-learning programme. The researcher conducted a tape-recorded focus group interview with seven participants who voluntarily agreed to participate. After transcription, the data was analysed using Tesch's (1992:92) method of analysis to code the data into themes in order to identify commonalities. The findings of this study indicated that participants experienced the evaluation process positively and negatively. The negative experiences included difficulty in obtaining access to evaluators, practica facilities, and inconsistencies of evaluators. Recommendations were made for improving evaluation of teaching skills of student tutors in this distance programme. / Health Studies / M. A. (Health Studies)

The research aims to analyze textualization regarding communication practices between tutors and distance learning students. Specifically the research aims to verify if the educational forum is considered pertinent for knowledge construction as well as identify subject?s behavior in e-Proinfo environment. The research also aims to understand the dynamics of the teaching and learning techniques related to the forum?s printed material. This is done in order to acknowledge discourse on behalf of subjects through the presented educational assignments. In order to address the issue, the work dealt with the relations present in distance learning forums, the forms in which the assignments are made, the way social actors interact and how this debate happens in the virtual environment. The research emphasized an educational forum used in a higher education institution at Rio Grande do Norte/Brazil. Thus the research corpus is composed by messages that were posted in the forum in the module called computer material . This module is one of the last in a set of six modules that are part of The Basic Cycle for Media Training promoted by the Center for Distance Learning in a public university at Rio Grande do Norte/Brazil. The research deals with a qualitative type approach in the perspectives of Merriam (1988), Cresswell (1994) and Minayo (1996). In order to achieve this analysis, the research dealt with theoretical landmarks related to distance learning present in (Silva, 2008; Brait, 1993; Sperbe and Wilson, 1986; Marquesi and Elias 2008 as well as Xavier, 2005, amongst others. As for aspects related to media and technological perspectives present in the forum, the research dealt with (Baranov, 1989; Neuner, 1981; Kearsley and Moore, 1996). Textualization was dealt according to (Marcuschi, 2008; Costa Val, 2004) and the conceptions and functions regarding tutors was seen according to (Salgado, 2002). In the conclusion and recommendations it was seen that these discussions present relevant contributions to distance learning and go beyond the practical universe present in electronical interaction. In the final considerations it is pointed out that this research is relevant for areas such as applied linguistics and presents guidelines for those involved in continuous education and aim meaningful knowledge that is coherent with distance learning education / Esta pesquisa tem como tema o ambiente de textualiza??o no ensino a dist?ncia, com foco no f?rum educacional utilizado por uma institui??o de ensino superior do Rio Grande do Norte, tendo como objetivo geral analisar a intera??o que se estabelece entre tutor e cursistas e suas implica??es para o processo de ensino e aprendizagem. Outros objetivos, mais espec?ficos, foram tamb?m considerados, tais como: verificar a pertin?ncia do f?rum educacional para a constru??o do conhecimento no ensino a dist?ncia, entender as fun??es dos pap?is desses sujeitos no e-Proinfo e, ainda, identificar na constru??o discursiva dos sujeitos frente ?s tarefas agendadas como ocorre a aprendizagem nesse ambiente. Para explorar o tema, tomamos por base uma problem?tica que interroga, sobretudo, em rela??o aos modos de intera??o no f?rum, como os temas s?o postos na discuss?o, como os atores sociais dialogam entre si e como ocorre o debate no ambiente virtual em fun??o da aprendizagem. O corpus comp?ese de mensagens postadas no f?rum durante o m?dulo Material Inform?tica , ?ltimo dos seis que integram o Ciclo B?sico do Programa de Forma??o M?dias na Educa??o, promovido pelo N?cleo de Educa??o a Dist?ncia (NEAD). A pesquisa caracteriza-se como uma abordagem qualitativa, na perspectiva de Merriam (1988), Cresswell (1994) e Minayo (1996) e situa-se no ?mbito da Lingu?stica Aplicada, tendo em vista que aborda quest?es que dizem respeito ao processo de ensino e aprendizagem em ambientes virtuais. Para a an?lise, recorremos a aspectos te?ricos referentes ao ensino a dist?ncia em autores como Silva (2008), Brait (1993), Sperbe e Wilson (1986), Marquesi e Elias (2008), Xavier (2005), entre outros. Com rela??o ?s m?dias e ?s perspectivas das tecnologias aplicadas ao f?rum, recorremos a Baranov (1989), Neuner (1981), Kearsley e Moore (1996); ao ambiente de textualiza??o Marcuschi, (2008), Costa Val (2004), assim como ?s concep??es e fun??es do tutor encontradas em Salgado (2002). Nos resultados, percebemos que a intera??o tutor-cursista fica comprometida pelo apagamento da tutora, que muitas vezes, se posiciona apenas como propositora do t?pico sem participar das discuss?es para o aprofundamento e fechamento avaliativo do conte?do sugerido, prejudicando assim a aprendizagem. Observamos tamb?m a aus?ncia de uma progress?o t?pica realizada pelos cursistas devido a falta de orienta??o e reorienta??o das quest?es discutidas, bem como pelo distanciamento da postagem de uma mensagem a outra. Desse modo, consideramos pertinente a participa??o dos cursistas e tutores de forma mais efetiva no espa?o interacional com vistas ? constru??o de novos saberes para a aprendizagem em ambientes de EaD

Indiana University-Purdue University Indianapolis (IUPUI) / The nursing shortage has reached unprecedented levels in the United States. In a response to meet current educational needs and demands to recruit, retain, and expand enrollment of students in baccalaureate programs in nursing, the growth of online education has been dramatic. As growth continues, graduation rates and program retention are a concern. The purpose of this study is to examine the relationship between student motivation, academic context, cost-benefit appraisal, and intent to persist in RNBS completion online programs. The conceptual model used in this study was Student Online Academic Persistence a researcher developed model which is primarily based on the work of Tinto, Bean & Metzner, and Rosenbaum. Research questions: 1. Among students enrolled in RNBS completion online programs, do motivation and context predict cost-benefit appraisal? 2. Among students enrolled in RNBS completion online programs, what is the relationship between cost-benefit appraisal and intent to persist in the program? Data were collected via a Web-based self-report questionnaire and subjected to descriptive and inferential analyses which included the use of linear regression and correlations. From a population of 3606 students from three schools of nursing who were enrolled in an RNBS completion online program, 704 usable surveys were returned, with a response rate of 19%. Technology self-efficacy correlated positively with goal orientation, goal commitment, satisfaction with institution and faculty, cost-benefit appraisal and intent to persist. Goal commitment to the program and satisfaction with institution were found to be important in the persistence of students. A continual decision making process involving cost-benefit appraisal was also found to impact student intention to persist in the program of study. Recommendations for faculty include assuring student technology self-efficacy and developing an online transition course designed to normalize the experience of adults engaging in online education. Future research which further tests the Student Academic Online Persistence model and explores the lived experience of the online student is suggested.

This study focuses on student support service quality with particular reference to an Open Distance Learning (ODL) environment. Taking student support services as anchors in mainstreaming ODL, the aims of the study are to develop an instrument that can accurately measure student support service quality in an Ethiopian ODL environment. Simultaneously, it is to investigate an alleged gap between students’ expectations and experiences of service quality in the Ethiopia-UNISA context. In doing so, an attempt is made to determine the students’ level of satisfaction with the student support services provided. The study relies on quantitative methods and a design-based research strategy, which involves iterative and step-by-step processes of investigation. The theoretical framework employed in this study is Gaps Model by Parasuraman, Ziethaml and Berry (1985). Using an instrument of which the possible level of external and internal validity has been ensured, data are collected and quantitatively analysed using a standard Statistical Package for the Social Sciences (SPSS). The data suggest that there are five dimensions that play a cardinal role in the measurement of student support service quality in an ODL context, namely supervision support, infrastructure, administrative support, academic facilitation and corporate image. In the Ethiopian context, there appears to be a discrepancy between students’ expectations and their experiences of the quality of student support services. More than often their expectations exceed their actual experiences of quality service provision. Students’ satisfaction levels are negatively affected by the quality of four of the support services provided by UNISA as measured through expectations and experiences. In contrast, the students’ responses show that they are highly satisfied with the corporate image UNISA holds both in Ethiopia and internationally. From among the five dimensions, however, corporate image and supervision support stand out to be the most important dimensions in contributing to the students’ satisfaction and dissatisfaction, respectively. As a recommendation, this study highlights that these two dimensions must be focal areas by UNISA as more effort must be exerted to build the image of UNISA in Ethiopia and to improve the supervision support provided to students. / Educational Leadership and Management / D.

Student assessment and feedback is not new to open and distance learning (ODL) but there is a paucity of empirical evidence as to its effectiveness in improving the performance of students and institutions. The objective of this study was to identify key aspects required to optimise feedback in ODL. In various studies, feedback has been heralded for its key role in the improvement of student learning. However, there are on-going expressions of uncertainty about whether assessment feedback is indeed delivering this potential, particularly in ODL mode. Against this backdrop of uncertainty and circumspection, this study offers a critical reflection on assessment feedback with particular focus on ODL. This case study was undertaken using semi-structured interviews with the students, which were conducted to explore and extrapolate their experiences and views on feedback. Focus group interviews with tutors were also conducted to provide an in-depth understanding of participants’ experiences and perceptions. Document analysis was used to make informed recommendations. The study recommends that creating an effective assessment programme, developing criteria, guides, exemplars and models; discussing and refining them and communicating them to students and their staff — will have a positive impact on the workload for staff with coordinating responsibilities. It is recommended that a student charter be devised to lay out student expectations alongside the expectations of an ODL institution. Such a student charter will ensure that both tutors and students know what is expected of them during the feedback giving and receiving process. My findings offer a deeper understanding of the assessment of code disciplines which require a specialist gaze for the judgement of student work, and the pressures experienced in this type of assessment in an ODL context. It is envisaged that the research findings will assist ODL practitioners with decisions related to assessment and feedback. There are clear implications for staff in ODL institutions to encourage changes in feedback culture. / Curriculum and Instructional Studies / D. Ed. (Curriculum and Instructional Studies)

The knowledge-driven, network society is founded upon technology. Educators need to implement technology effectively into the three main pillars of education, namely teaching, learning and assessment. This would assist students to become independent, confident and motivated life-long, self-directed learners that can use technology effectively in an educational environment. It would also ensure that graduates are able to become change agents, transferring their knowledge, skills and values to others in their communities. Alternative assessment methods that are technology driven could enable both educators and students to become more effective in a network society. This study advocates the use of alternative assessment methods by using technology driven assessment tools for possible replacement of traditional, paper based and "one size fits all" assessment methods within the subject field of Theology. Document analysis was used in a broad sense to evaluate technology-based multimedia documents. Ten documents were identified and evaluated as possible alternatives for traditional assessment methods. Inter-rater reliability ensured that the investigation provided constant estimates and results. The SECTIONS model used for this evaluation provided opportunities to include criteria important for higher education, the use of technology and subject relevant information to ensure that the evaluation was done with a specific purpose and scope in mind; to find technology-based tools that can substitute traditional assessment tools in order to enhance effective education to students. / Educational Studies / M.

This study was conceptualised within a social-constructivist ontological orientation and, further, uses an interpretive epistemological lens to extract information from the participants who are coming from different life worlds. This thesis, Effective assessment in open distance and e-learning: using the Signature Courses at the University of South Africa as a model for future practice, investigated how emerging information communication technologies (ICTs) can be used to transform, enhance and influence student assessment practices in Open Distance and e-Learning (ODeL) contexts. The ultimate objective of the study was to establish assessment guidelines for effective student assessment in distance education using technology as an enabler. To achieve the objectives of this study, a mixed methods research methodology was adopted in which Unisa lecturers’ and first-year students’ experiences, perceptions, attitudes, and beliefs regarding the use of ICT as a tool to enhance and influence student assessment were sought. Despite some limitations, the study was able to reveal that technology has the potential to influence student-lecturer, and student-peer interaction thereby bridging the isolation gap that normally exists between them. Further, these potential benefits also include the identification of teaching strengths and weaknesses, the indication of areas where instructional change or modification is needed, and the application of more effective means of interacting with students. A key function of this study, therefore, is to help the lecturers involved in higher learning assessment to use technology effectively and efficiently to enhance assessment practices as a means of maintaining both the academic standards and enhancing the quality of the student learning experience. In addition, the study has shown that technology has the potential to enhance and influence student learning and motivation. Furthermore, this study made theoretical and practical contributions to the literature on information communication technology implementation on lecturers’ and students’ pedagogical and technological readiness to online learning and assessment in open distance and e-learning. / Curriculum and Instructional Studies / D.
