Because mobile technologies are overtaking personal computers as the primary tools of Internet access, and cloud-based resources are fundamentally transforming the world's knowledge, new forms of teaching and assessment are required to foster 21st century literacies, including those needed by K-12 teachers. A key feature of mobile technology…

The challenges that massive open online courses (MOOCs) bring to the learning arena spur adult educators to improve delivery. A framework for a new type of MOOC is presented to address some of the challenges presented by earlier models. This new MOOC, called a mesoMOOC, can bridge several challenges that hinder current effective delivery of MOOCs…

We investigate how the computerized dynamic assessment system improves the learning achievements of vocational high school students studying accounting. Our experiment was conducted under the one-group pretest-posttest design of 34 junior students. The questionnaire results were analyzed to determine student-learning attitudes and reactions toward…

Some evidence has emerged in recent years that plagiarism can be reduced through the use of online mastery tests that are designed to train introductory psychology students in awareness of academic integrity and referencing conventions. Although these studies demonstrated a reduction in incidents of plagiarism they did not directly examine whether…

The present set of 7 experiments systematically examined the effectiveness of adding causal explanations to simple refutations in reducing or eliminating the impact of outdated information on subsequent comprehension. The addition of a single causal-explanation sentence to a refutation was sufficient to eliminate any measurable disruption in…

Sensitivity to spacing information within faces improves with age and reaches maturity only at adolescence. In this study, we tested 6-16-year-old children's sensitivity to vertical spacing when the eyes or the mouth is the facial feature selectively manipulated. Despite the similar discriminability of these manipulations when they are embedded in…

Highly abstract predicates (e.g. "think") present a number of difficulties for language learners (Gleitman et al., 2005). A partial solution to learning these verbs is that learners exploit regularities in the syntactic frames in which these verbs occur. While agreeing with this general approach to learning verbs, we caution that this…

Information communication technologies (ICT) in education is an expanding field, and within this field there is a need for development of effective systems for faculty and learners to communicate feedback and assess performance. The increasing migration of many academic disciplines and courses to an online format has prompted an increased need for…

This article reports the design, development, and evaluation of an online software application for assessing students' understanding of curricular content based on concept maps. This computer-based assessment program, called the Assessment Agent System, was designed by following an agent-oriented software design method. The Assessment Agent System…

The present study investigated students' perception of computerized TOEFL test. Subject of this study were 100 adult male and female students who took the iBT TOEFL test in Iran. Participants were provided with a researcher-developed questionnaire on the advantages and disadvantages of Computer-Based Test (CBT) compared to Paper- Based Test (PBT).…

In this dissertation, I explore unsupervised techniques for the task of automatic short answer grading. I compare a number of knowledge-based and corpus-based measures of text similarity, evaluate the effect of domain and size on the corpus-based measures, and also introduce a novel technique to improve the performance of the system by integrating…

Working memory span tasks are popular measures, in part, because performance on these tasks predicts performance on other measures of cognitive ability. The traditional method of span-task administration is the experimenter-paced version, whose reliability and validity have been repeatedly demonstrated. However, computer-paced span tasks are…

We investigated whether success in number-conservation and class-inclusion tasks relies on a general ability to inhibit misleading strategies. Two groups of 10-year-olds performed inter-task priming between computerized versions of class-inclusion and number-conservation tasks (Experiment 1). In one group, the class-inclusion task served as a…

Derived from Vygotsky's works, dynamic assessment (DA) enables learners to move beyond their current level of functioning through offering needs-sensitized mediation. This study aimed at exploring the learners' development in novel and increasingly more challenging situations called transcendence (TR) in an L2 context focusing on reading…

Dynamic Assessment (DA) is a postmodern notion in testing which sees instruction and assessment as inextricably mingled contending that learners will progress if provided with dynamic interactions. The main purpose of the study is to see if the scores generated by the computerized dynamic assessment (C-DA) which is grounded in Vygotsky's…
