Ashok Kumar J, Abirami Murugappan

Show Abstract

Abstract:

Open and Distance education is the form of education that delivers pedagogy, technology, and instructional designs to students who are not physically available at the same place in a traditional classroom or campus. Opinion mining (also called sentiment analysis) plays an important role in the field of social media. It computes people’s polarities such as positive, negative, neutral, which were expressed in online social media contents at various levels, namely, document level, sentence level, and corpus level. In this research paper, a multi-aspect based opinion mining system is proposed by applying opinion mining techniques for Open and Distance Education social media contents. The purpose of this research is to measure the public satisfaction of open and distance at the title level, document level, sentence level, and aspect level. The proposed system was employed by the data collection process, preprocessing, feature extraction, opinion detection and polarity classification using the Naïve Bayles classifier. The detected opinions at various levels are also visualized. The performance of the system is evaluated using precision, recall, f-measure, and accuracy.

Elias Rankapola

Show Abstract

Abstract:

This study focused mainly on the learners’ perspective and experiences with regard to the usage of lecture podcasts as opposed to the researcher’s perspective. To obtain the learners’ perspective, hypotheses were formulated to guide the study. Quantitative methods were employed to collect data and perform statistical analysis. Four hypotheses were fully supported whilst only one hypothesis was rejected. The outcome of the study attested that generally, learners are very receptive to podcasting technology and that lecture podcasts helped to enhance learning and accommodate different learners. This practice led to improved test grades. However, learners also indicated that lecture podcast should complement the traditional lecture.

Raj Kiran Doley

Show Abstract

Abstract:

Open and distance learning today has gained its momentum both in popularity and effectiveness amongst those who have not got the opportunity to join formal mode of education due to various reasons like inadequate time or financial hardship. Despite this, it is felt that the system of open and distance learning can be made more effective and result-oriented particularly in the Indian context. Some new innovative strategies can be developed to be included in this system, which is being analyzed and highlighted through this paper. The role of Information & Communication Technology (ICT) in education is very crucial in today’s pedagogy for an improved system of knowledge sharing. The present paper tries to suggest some strategies by which the ICT will be used as a tool for effective teaching-learning. The Government has notified that the qualification earned through open & distance learning mode is at par with that of the formal mode of education. This has complimented in attracting more and more working people towards this system of education through which such people can fulfill their desires of strengthening their academic career while in service.

The recent trends of open & distance learning have also created some negative impressions in the academic fraternity mainly owing to the unfair and illegal means through which degrees are improperly awarded by some institutions offering such programmes. While dealing with such illegal practices, the authorities have even closed down a number of institutions offering courses in the open and distance mode. This paper endeavours to find out the best ways to obtain assured quality education and steps to improve the existing system of open and distance learning for a country like India.

Show Abstract

Abstract:

This study examines the important of e-board learning and its effect in teaching at Defence University in Sri Lanka. Even after 3 years of usage of e-Boards there are some practical issues on usage of e-Boards. Therefore this study examines students’ and teachersimpact on e-board for learning and teaching process. In a developing country the importance of underlying information technology principles that are critical for an in-depth learningby e-board platform. A structured multiple choice questionnaire was distributed among students’ and lecturesthat were enrolled and employed at the General Sir John Kotelawela Defence University, Sri Lanka. A total of 300 students and 30 lectures participated in this study and completed written and online questionnaire related to e-board. The outcome of this study shows that there is a strong positive response on e-board learning among students and they believe lack of support from the technical support to improve the current situation. Lecturer’s perspective was entirely different they believe mixture of traditional method or blend will improve the quality of learning than eboard. Therefore there were somewhat 50% or more lectures avoid using the new technology due to this reason. Both parties believe that e-board is better than multimedia. Although the outcome is preliminary in nature, the results provide cause for concern over the status of e-board education in Sri Lanka which is not satisfactory

EFFECTS OF COLLABORATIVE M-LEARNING AND INDIVIDUAL ELEARNING ON THE ACADEMIC PERFORMANCE, ATTENTION BENEFIT AND CONSISTENCY OF LEARNING

Ananta kumar Jena, Kabita Pokhrel

Show Abstract

Abstract:

This study was a pre-test post-test non equivalent quasi-experimental design where both the experiment groups pretested. after an initial training, Experiment group 1 practiced through collaborative mobile learning for 3 months with 30-minutes session each day. Meanwhile, the experimental group 2 practiced individual e- learning with similar time frame and duration of learning and practice. The objective of the study was to study the effect of collaborative Mlearning and individual E-learning on the academic performance, attention benefit and consistency of learning of the learners over the traditional approach of learning. To conduct the experiment, the researcher has selected 125 university students out of three Indian universities. The sample students were randomly selected from MA (Education) odd semester, those were the targeted population. Out of more than 10,000 PG students of five universities of Assam, the researcher has randomly selected odd semesters from three education departments from three Universities. It was found that collaborative mobile learning and individual e-learning provides better academic performance among the students over the traditional approach. It was generalized that new method creates awareness among the learners over traditional approach. In this 21st century learners are thinking freedom of learning which is beyond normal classroom situation. That is why students were performed better in collaborative m-learning and individual e-learning but not in a traditional mode.

E-LEARNING AT THE UNIVERSITY OF CAPE COAST, GHANA-ARE OUR DISTANCE EDUCATION STUDENTS TECHNOLOGICALLY READY?

John K.E. Edumadze, Joseph I. Ogoe, Gabriel Essilfie, Gladys E. Edumadze, Alex Osei-Gyasi A., Robert E. Graham

Show Abstract

Abstract:

Since the adoption of e-learning involves high investment cost, Educational Institutions are expected conduct considerable up-front analysis to assess readiness among their stakeholders-lecturers, administrators and students in order to derive maximum benefit. Thus the study was conducted to measure University of Cape Coast Distance Education (UCC DE) students’ perceived readiness to engage in e-learning. The research design adapted was a descriptive survey, using open- and close-ended questionnaire developed through literature search to solicit responses from students’ readiness (self-assessment or perception). The results show that majority of DE students have diverse basic computing and Internet skills with regular Internet access. However, they have very little or no experience with LMS tools and majority are less freely willing to fund their e-learning activities. The study then recommended ICT and e-learning skills training as a solution to reduce or minimise the identified deficiencies.

HOW ONLINE COURSEWORK IMPROVES THE EDUCATIONAL ATTAINMENTS IN CLINICAL TRANSPLANTATION

Ahmed Halawa, Ajay Sharma, Julie M Bridson, Denise Precott, Sarah Lyon, Arpan Guha, David Taylor

Show Abstract

Abstract:

Introduction: Distance education is not yet popular in clinical medicine due to the strongly ingrained belief among medical professionals that face-to-face and bedside teaching is a pre-requisite to learning clinical medicine. Transplantation Science is a challenging subspecialty to teach and we demonstrate how our educational approach can be effective in improving the attainment of the postgraduate students. Methods: This online course was designed in the UK by an international board of academic and clinical experts and attracted international students (n=28) from 12 countries. The diversity of the student demographics presents inherent challenges mainly due to a fundamental disparity between perception and implementation of the knowledge. We employed multi-disciplinary coursework as the main strategy to improve the attainment of these students to overcome these challenges. Results: The significant attainment changes noted by implementing multi-disciplinary coursework-based pedagogy is exemplified by qualitative and quantitative improvement in performance in the final assessment marks when compared to the first assignment (66% ± 3.2 vs 56% ± 5.1, P <0.05). This improvement is reflected in ‘habitual use’ of critically reflective practice and implementation of evidence-based medicine. Conclusions: Well-designed, multi-disciplinary formative coursework is a valuable tool to develop the attainment of postgraduate sub-specialty trainees perusing a career in clinical medicine.

LEARNING SCIENCE THROUGH DISTANCE EDUCATION- A CHALLENGE AT KARNATAKA STATE OPEN UNIVERSITY

T. S. Harsha

Show Abstract

Abstract:

Distance education is the education of students who may not always be physically present at a class room. The modern use of electronic educational technology (also called e-learning) facilitates in distance learning and independent learning by the extensive use of Information and Communications Technology (ICT), replacing traditional content delivery by postal correspondence in general and for science discipline in particular. Science is an art related to field of study which draws upon many disciplines such as chemistry, physics, physiology, biology, hygiene, economics, rural development, child development, sociology and family relations, community living, art, food, nutrition, clothing, textiles and home management. The science, technology, society and environment education movement has a long history in science education reform, and embraces a wide range of theories about the intersection between science, technology and society. In delivering science courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. On developing strategies for successful Science and technology programme in Distance Education is to identify relevant mode to approach and to define and prioritize short and long-term objectives and the need to align the agenda with requirements. The present paper attempted to understand the challenges in Open and Distance mode with special reference to science subjects at KSOU and analyze the reasons in teaching science stream, and throw some light on the possible ways of solving the problems of ODL and encourage learner’s scientific mind.
