Courseware repositories contain large amounts of lecture videos and text. When searching for lecture material on a given topic, it would be useful if the repository also indicates the topics that are pre-requisites. In this paper we present a technique that automatically constructs the ontology (dependency graph) from the given lecture notes. We show how this ontology can be used to identify the pre-requisites...
Electronic learning(e-learning) is used to access the learning content using desktop computers. But the limitation with e-learning is its immobility. Mobile learning(mlearning) is an advanced stage of e-learning where in the learner is equipped with handheld mobile device to access the learning content using various wireless technologies. Though m-learning provides mobility, it is not context sensitive...
Many universities offer distance learning by recording classroom lectures and making them accessible to remote students over the Internet. A university's repository usually contains hundreds of such lecture videos. Each lecture video is typically an hour's duration and is often monolithic. It is cumbersome for students to search through an entire video, or across many videos, in order to find portions...
Technology has grown rapidly with scientific advancement over the world in recent decades. Therefore, there is a need to redesign the educational system to meet industrial needs better. The advent of computerswith sophisticated software hasmade it possible to solve many complex problems very fast and at a lowercost. Almost all studies in various disciplines use computers to solve their problems. Making...
We propose a novel method to recognize symbols of the American Sign Language alphabet (A-Z) that have static gestures. Many of the existing systems require the use of special data acquisition devices like data gloves which are expensive and difficult to handle. Some of the methods like finger tip detection do not recognize the alphabets which have closed fingers. We propose a method where the boundary...
With advent of mobile technology and its huge popularity, mobile devices become truly ubiquitous and they can serve as ideal tools for learning. Though there may not be much difficulty in accessing the learning content using desktop PCs and laptops, accessing the content using mobile devices makes a difficult task because of the varying device capabilities and form factors. Ubiquitous learning systems...
One of the grand challenges in computing education is to teach programming to novice students. Typically, novices find it difficult to understand compiler error messages. Hence a prototype of web based programming assistance tool has been developed to assist them in the programming process. It is an online program development environment to help beginners to debug programs in C language. The debugger...
In educational and professional environments, effective communication (e.g. reading, writing, speaking, and teaming) is important and can be developed with a variety of activities and assignments. This paper summarizes ways that wikis can facilitate these practices and help educators to achieve their goals, and provides examples of successful wiki activities.
This paper presents a case study wherein 498 school Computer Literacy teachers spread all over the State of Goa, were trained over a 2 year period by Goa University, using a blended approach, under the Post Graduate Diploma in Computers and Educational Technology (PGDCET) project. The paper gives a brief description of the approaches used in designing and implementing the course. In particular, it...
Tectonic shifts are rapidly occurring in the education-space. Two streams of thought are rapidly emerging: Current academia produce fails to meet industry expectations, thus, impacting employability readiness of fresh entrants into the corporate; Life-style changes in millennials, concomitant with technology advancements, rendering current academic approaches inadequate, and outdated This paper reflects...
The key characteristic of adaptive learning technologies implies specific challenges for evaluation. Despite an increasing awareness of the need for sound evaluations, the current evaluation practice still suggests considerable weaknesses in the approaches applied and calls for further research on appropriate and sophisticated evaluation methodologies. This paper aims at further advancing the maturity...
The need for Information Communication Technology (ICT) in education today cannot be over-emphasized. An ICT-enabled pedagogy entails that the teachers take on newer and challenging roles to facilitate an effective teaching-learning process. In this context, our tutorial is an attempt to bring out the key elements of facilitation required in using an ICT-enabled method for teaching-learning. In particular,...
Are we teaching students what to think but not how to think? Drawing upon considerable experience in using educational technologies in the classroom and in teaching pure online courses, we explore the potential of such technologies for deep learning, more specifically, learning that can further critical thinking, creative thinking, and wisdom, regardless of the subject domain. We present actual examples...
E-Learning that blends the internet, the web and the educational activities, is becoming one of the prominent ways for defining teaching and learning experiences as anywhere anytime process. Any teaching learning process must be designed to suit the needs of all and must consider all types of learners including people with disabilities. One of the major learning disabilities found related to learners...
The shortage of experimental platforms needed for learning IT systems in a hands-on way is one reason for the lack of quality education in the area of IT. For most students who have access to a PC, their ability to experiment on that machine is limited by the risk of possible irrecoverable damage their experimentation may cause to the equipment. We report the development of a 'Virtual Laboratory for...
Proving program correctness has a significant side-benefit of leading the step-wise systematic development of programs. Correctness is proved formally using predicate logic, which requires certain mathematical maturity from the programmer. This work proposes a diagrammatic reasoning tool for representing the predicates, with a minimal blend of symbolic notation, thus providing an easy-to-use tool...
In this paper, we discuss a model for large-scale synchronous distance mode teacher training. A two-week workshop using satellite and Internet was conducted in a synchronous distance mode, in which 641 teachers from 218 engineering colleges participated. We conducted a survey to determine participants' feedback and role of factors such as, gender, age, qualification and location of college in the...
The success of e-learning systems depends heavily on high quality content being available. They can be prolific only if regular teachers and educators (who are not professional content creators) are able to easily create and use learning content. Standards such as SCORM allow reusable learning objects (RLOs) to be created and shared across the e-learning community. However, the existing tools and...
