This paper presents a case study conducted by two universities seeking to explore Open Education Resources (OER) in their precalculus course. Students not only gained access to their textbook for free on the first day of class, but also Lumen OHM, an online mathematics assessment platform. The majority of students involved in the study were…

The development of six online quizzes to support students' study of an introductory mathematics masters module at The Open University is described and their use evaluated. The quizzes were implemented using the "STACK" online e-assessment system, which is powered by a computer-algebra engine. Evaluation of student feedback and an initial…

Online teaching is growing in popularity. This paper presents a case study for an online business course investigating student exam scores obtained from non-randomized and randomized exams. We find that the non-randomized exam scores of the students are suspicious because there are statistically significant disparities from the randomized exam…

The present trend in developing and using semi-direct speaking tests has been supported by test developers and researchers' claim of their increased practicality, higher reliability and concurrent validity with test scores in direct oral proficiency interviews. However, it is universally agreed within the language testing and assessment community…

The eight-item eHealth Literacy Scale (eHEALS) is a previously validated scale developed to assess consumers' combined knowledge, comfort, and perceived skills at finding, evaluating, and applying electronic health information to health problems. In the present study, a Chinese version of the eHEALS was developed and its psychometric properties…

This paper deals with optimal partitioning of limited testing time in order to achieve maximum total test score. Nonlinear optimization theory was used to analyze this problem. A general case using a generic item response model is first presented. A special case that applies a response time model proposed by Wang and Hanson (2005) is also…

Item parameter estimates vary for a variety of reasons, including estimation error, characteristics of the examinee samples, and context effects (e.g., item location effects, section location effects, etc.). Although we expect variation based on theory, there is reason to believe that observed variation in item parameter estimates exceeds what…

This book is designed to help readers reflect upon their personal approaches to open and distance learning (ODL) assessment and to adapt their techniques to benefit learners. Part A explores issues and themes in ODL assessment. It examines key terms in assessment; the important relationship between assessment and learning; unique issues of…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
