Many organizations utilize some form of automation in the test assembly process; either fully algorithmic or heuristically constructed. However, one issue with heuristic models is that when the test assembly problem changes the entire model may need to be re-conceptualized and recoded. In contrast, mixed-integer programming (MIP) is a mathematical…

Machine learning is a popular topic in data analysis and modeling. Many different machine learning algorithms have been developed and implemented in a variety of programming languages over the past 20 years. In this article, we first provide an overview of machine learning and clarify its difference from statistical inference. Then, we review…

LiaScript is an attempt to enable everyone to create free and interactive online courses, without the need of being an experienced programmer. Instead, it aims to bring both parties, software- and course-developers, closer together by introducing Open-Source techniques into the Open-courSe development process. LiaScript was designed to be…

The quantitative evaluation of experimental data and their graphical presentation are integral to teaching and research in chemistry and the life sciences. Data are commonly fitted to physical models, which in all but the simplest cases are expressed as nonlinear mathematical functions. To facilitate data evaluation in both teaching and research…

This study aims to explore an educational learning environment that supports students to learn conceptual modelling with the unified modelling language (UML). In this study, we call the describing models "UML programming." In this paper, we show an educational UML programming environment for science, technology, engineering, art, and…

The traditional method of assessment (examination) is often characterized by examination questions leakages, human errors during marking of scripts and recording of scores. The technological advancement in the field of computer science has necessitated the need for computer usage in majorly all areas of human life and endeavors, education sector…

The US Bureau of Labor Statistics predicts over 8 million job openings in IT and computing, including 1 million cybersecurity postings, over the current five-year period. This paper presents lessons learned in preparing middle-school students in rural Georgia for future careers in computer science/ IT by teaching computer programming in the free,…

Lectures of courses at universities are increasingly being recorded and offered through various distribution channels to support students' learning activities. This research work aims to create an automatic system for producing and distributing high quality lecture recordings. Opencast Matterhorn is an open source platform for automated video…

This paper describes the framework for the development of OER-based learning materials "TCC121/05 Programming Fundamentals with Java" for ODL learners in Wawasan Open University (WOU) using three main development phases mainly: creation, evaluation and production phases. The proposed framework has further been tested on ODL learners to…

This paper describes an integration of different Relational Database Management System (RDBMS) of two Course Management Systems (CMS) called Sakai and the Common Factory for Inspiration and Value in Education (CFIVE). First, when the service of CMS is provided campus-wide, the problems of user support, CMS operation and customization of CMS are…
