This thesis focuses on learner support in Chinese distance education. It draws a picture of Chinese modern distance education, covering the major issues in the field of learner support, and small group work as peer support. The aim of the study is to find out whether or not the learner support, that distance students at university level obtained, has the tendency to support students’ deep learning. The aim has been achieved by examining learner support in six institutions of ICT-based distance education in China. Three other sources of learner support are investigated. The main objectives of the study are: 1) to describe the distance students’ characteristics; 2) to examine their learning habits, learning organizations, and their interactions; 3) to investigate the student support provided by the institutions; family support; societal support; and peer support in the form of small group work. The purpose of this study is to define current practices of learner support in the six distance education institutions, determining the extent of similarities and differences on learner support services among these institutions. The study is applying a case-study approach, using qualitative and quantitative methods to investigate the six Chinese distance education institutions. During the first stage, several field visits were conducted in different research sites with on-site participant observation, non-participant observation and interviews for obtaining knowledge of Chinese distance education. In the second stage, a survey with a student questionnaire was distributed to students present and others online, in total 587. In addition, semi-structured interviews with staff members (administrators, instructors and tutors), individual students, and student focus groups were performed. The present research is one of the few in-depth case studies that focus on the relation between learner support system and different approaches to learning. On the basis of these research findings, the importance of a well-designed learner support system for the distance learner, a system for fostering creative, critical or independent thinking skills, or deep learning, in line with Chinese cultural and social conditions, is underlined.

Web-based learning should move away from static transmission of instruction to dynamic pages for effective interactive learning. Furthermore, automated assessment of learning should move beyond rigid quizzes or multiple-choice questions. This study describes the design, development, implementation, testing and evaluation of two prototypes of an electronic assessment tool to enhance the effectiveness of automated assessment. The tool was developed in the context of a distance-learning organisation and was built according to a development research model entailing a cyclic design-intervention-outcomes process. The first variant, E-Grader, was developed to test an algorithm for assigning marks to open-ended textual responses. The second variant, Web-Grader, was an interactive web-based extension of E-Grader. It provided immediate interactive support to students as they responded textually to content-based questions. This multi-disciplinary study incorporates principles and techniques from software engineering, formal computer science, database development and instructional design in the quest towards electronic assessment of web-based textual inputs. / Computing / M.Sc.

This study was motivated by the need to overcome the pedagogical hindrances experienced by introductory object-oriented programming students in order to address the high attrition rate evident among novice programmers in distance education. The initial phase of the research process involved exploring a variety of alternative visual programming environments for novices. Thereafter the selection process detailed several requirements that would define the ideal choice of the most appropriate tool. An educational tool Raptor was selected. Lastly, the core focus of this mixed method research was to evaluate undergraduate UNISA students’ perceptions of the Raptor e-learning tools with respect to the perceived effectiveness in enhancing novices’ learning experience, in an attempt to lower the barriers to object-oriented programming. Students’ perceptions collectively of the Raptor visual tool were positive and despite the fact that the sample size was too small to achieve statistical significance, these quantitative and qualitative results provide the practical basis for implementing Raptor in future. Thus providing learning opportunities suited to learner interests and needs, can lead to an enormous potential to stimulate individuals’ motivation and development in creating a more positive learning experience to overcome barriers in programming and enhance concept understanding to address the diverse needs of students in distance education that could lead to a reduced dropout rate. / Computing / M.

Das Thema Information Retrieval hat insbesondere in Form von Internetsuchmaschinen eine große Bedeutung erlangt. Retrievalsysteme werden für eine Vielzahl unterschiedlicher Rechercheszenarien eingesetzt, unter anderem für firmeninterne Supportdatenbanken, aber auch für die Organisation persönlicher E-Mails. Eine aktuelle Herausforderung besteht in der Bestimmung und Vorhersage der Leistungsfähigkeit einzelner Komponenten dieser Retrievalsysteme, insbesondere der komplexen Wechselwirkungen zwischen ihnen. Für die Implementierung und Konfiguration der Retrievalsysteme und der Retrievalkomponenten werden Fachleute benötigt. Mithilfe der webbasierten Lernanwendung Xtrieval Web Lab können Studierende praktisches Wissen über den Information Retrieval Prozess erwerben, indem sie Retrievalkomponenten zu einem Retrievalsystem zusammenstellen und evaluieren, ohne dafür eine Programmiersprache einsetzen zu müssen. Spielemechaniken leiten die Studierenden bei ihrem Entdeckungsprozess an, motivieren sie und verhindern eine Informationsüberladung durch eine Aufteilung der Lerninhalte. / Information retrieval has achieved great significance in form of search engines for the Internet. Retrieval systems are used in a variety of research scenarios, including corporate support databases, but also for the organization of personal emails. A current challenge is to determine and predict the performance of individual components of these retrieval systems, in particular the complex interactions between them. For the implementation and configuration of retrieval systems and retrieval components professionals are needed. By using the web-based learning application Xtrieval Web Lab students can gain practical knowledge about the information retrieval process by arranging retrieval components in a retrieval system and their evaluation without using a programming language. Game mechanics guide the students in their discovery process, motivate them and prevent information overload by a partition of the learning content.
