A computational experiment that investigates the optical activity of the amino acid valine has been developed for an upper-level undergraduate physical chemistry laboratory course. Hybrid density functional theory calculations were carried out for valine to confirm the rule that adding a strong acid to a solution of an amino acid in the l…

Oscillating chemical reactions (OCRs) have been known since 1828, with the Belousov-Zhabotinskii (BZ) reaction the most studied example. Initially, OCRs were considered to be special cases due to the small number detected and because the oscillatory behavior did not seem to agree with the second law of thermodynamics. However, OCRs have become…

The study of chromatin constitutes one of the most active research fields in life sciences, being subject to constant revisions that continuously redefine the state of the art in its knowledge. As every other rapidly changing field, chromatin biology requires clear and straightforward educational strategies able to efficiently translate such a…

This study examines the effects of a new CAI program designed to remediate text comprehension difficulties in less skilled comprehenders at the beginning of learning to read. In a randomized control trial design, two groups of second grade children experiencing comprehension difficulties were selected and trained using two CAI programs. One of…

E-learning technologies have allowed authoring and playback of standardized reusable learning objects (RLO) for several years. Effective mobile learning requires similar functionality at both design time and runtime. Mobile devices can play RLO using applications like SMILE, mobile access to a learning management system (LMS), or other systems…

This study explored the curriculum orientation preferences of K-12 public school teachers who provided instruction in virtual settings (n = 47) in a midwestern state. Curriculum orientations were explored using a mixed-methods design. Quantitative assessments data revealed a pattern of curriculum orientations similar to teachers working in…

In CSCL research, collaborative activity is conceptualized along various yet intertwined dimensions. When functioning within these multiple dimensions, participants make use of several resources, which can be social or content-related (and sometimes temporal) in nature. It is the effective coordination of these resources that appears to…

Purpose: Traditional evacuation drill is monotonous. Therefore, evacuation drill should be diversified to get more people interested in disaster prevention. Our idea is game-based evacuation drill using real world edutainment (RWE). This paper aims at clarifying how RWE-based evacuation drill is realized. Design/methodology/approach: RWE provides…

Introduction: Nowadays, language and intercultural competences have become core employability skills in many fields, supporting the development of other skills which emphasizes the necessity for specific pedagogic approaches in developing online learning materials and courses that would develop learners' language competence and other relevant 21st…

This study explored how students viewed the role of ideas for knowledge work and how such a view was related to their inquiry activities. Data mainly came from students' online interaction logs, group discussion and inquiry, and a survey concerning the role of ideas for knowledge work. The findings suggest that knowledge building was conducive to…

Instructional methodologies increasingly require teachers' efficacy and implementation of computer-assisted learning (CAL) practices in general and particularly in the science classroom. The South African National Education Department's e-Education[1] policy also encourages the use of computers and computer software in implementing outcome-based…

This study examined the effects that computer-assisted instruction had on students' attitudes toward a mathematics lesson and toward learning mathematics with computer-assisted instruction. The computer software we used was based on the ASSURE Instructional Systems Design and the ARCS Model of Motivation, and the software was designed to teach…

This article outlines research into innovative language teaching practices that make optimal use of technology and Computer-Mediated Communication (CMC) for an integrated approach to Project-Based Learning. It is based on data compiled during a 10- week language project that employed videoconferencing and "machinima" (short video clips…

Research shows that computer-generated corrective feedback can promote second language development, but there is no consensus about which type is the most effective. The scale is tipped in favor of more explicit feedback that provides metalinguistic explanations, but counterevidence indicates that minimally explicit feedback of the…

Structured argumentation support environments have been built and used in scientific discourse in the literature. However, to the best our knowledge, there is no research work in the literature examining whether student's knowledge has grown during learning activities with asynchronous argumentation. In this work, an intelligent computer-supported…
