The teaching and learning of algebraic word problems is a basic component of elementary education. Recently, to facilitate its learning, a few approaches for automatically solving algebraic and arithmetic word problems have been proposed. These systems generally use either natural language processing (NLP) or a combination of NLP and machine learning. However, they have low accuracy due to their large...
One form of educational inequality is the disparity that exists between urban and rural settings. Equal distribution of quality education is a challenge for developing countries due to the unavailability of resources. Various approaches to equal distribution are distance learning, telecast learning and e‐learning; however, these approaches cannot achieve the desired objectives due to their limitations...
Two groups had participated in a study on the effectiveness of Semantic Web based mobile application for preschool cognitive skills learning. The first group had the traditional method with textbooks and teacher's teaching. The second group worked with the proposed application at school along with the classroom sessions. A quasi experimental pre and post tests model was conducted to measure the learning...
Primarily preschool cognitive skills are abilities of acquiring generic knowledge. Generic knowledge is said to be the knowledge about kinds of things. Currently these cognitive skills are taught through the use of pre-authored (in the form of books or worksheets) learning contents containing the objects and concepts of the real world. This method of teaching is known as instructional pedagogy that...
Requirements change management is a vital activity of the software development and even after maintenance. When we change one requirement it effects the other requirements of the system. A proper impact analysis maintains a repository of changing requirement, reusing previous experiences and reduces rework effort, is also essential for better requirement change management. There is also a need of...
Intelligent tutoring system (ITS) is a contribution from Artificial Intelligence domain. It is an expert system that has a very effective role in modern education. It facilitates both teachers and students in teaching or learning of some concept of a domain. Despite of large number of benefits from ITS, yet very few people have experienced it in real environment. It is primarily due to high complexity...
In semantic cache query processing, an important step is query trimming. Trimming a query can potentially reduce the answer size that is required to retrieve from a remote server. Existing query trimming technique is based on Boolean logic, which inhibits several shortcomings such as after trimming it expands number of predicate terms and induces disjunction even if conjunctive queries are under consideration...
Software practitioners realized the importance of software processes back in early 70's, that software quality could only be achieved by following a disciplined way. Previous work contributed heavily to this field, but every proposed process fits only to a given scenario. Software process improvement (SPI) produced new processes based on previous one. Still SPI is ongoing, creating more diversity...
