Videos, generally a fun and effective teaching tool, can be a source of stress for students who are deaf or hard of hearing--especially when shown in classrooms in which a handful of deaf or hard of hearing students find themselves surrounded by students who hear. In fact, for deaf and hard of hearing students, video watching may be a source of…

This paper describes the application of new Virtual Learning Environments (VLEs) in engineering education. It demonstrates how VLEs improve student learning in two engineering concepts compared with the traditional classroom setting. Literature has conflicting studies on both the advantages and disadvantages of learning in VLEs. The application of…

One apparent challenge associated with learning analytics (LA) has been to promote adoption by university educators. Researchers suggest that a visualization dashboard could serve to help educators use LA to improve learning design (LD) practice. We therefore used an educational design approach to develop a pedagogically useful and easy-to-use LA…

This paper considers emotions and learning through multimedia learning, mediated message processing, and affective computing. In multimedia learning, the emotional design includes all relevant features from the visual design, so emotional and motivational features are given through visual appeal. The Limited Capacity Model of Motivated Mediated…

The central focus of my dissertation concerns the issue of representation. The issue of representation is important for science education research for two reasons: (1) the use of external representation in science teaching and learning, particularly in chemistry education, is ubiquitous as microscopic entities are not directly visible, and (2) the…

Videos as instructional materials have become an important part of higher education. The ability of videos to be shared and used in social and educational settings demonstrates their increasingly significant contemporary impact. Identifying the video features that affect student engagement as a success indicator can therefore contribute to the…

The introduction of Computational Chemistry via "Molecular Modelling and Drug Design" course at undergraduate level has opened wide possibilities for students to expand their knowledge of quantum chemistry, organic reaction mechanisms, protein-ligand interactions, drug design, and probable "in vivo" behavior of drug candidates.…

Chemical kinetics is a branch of physical chemistry that constitutes an essential part of undergraduate education. In general, a complex and expensive experimental apparatus is indispensable for observing the kinetics of a chemical process owing to the continuity of chemical reactions. Thus, intuitive visualization of the chemical kinetics using a…

Potential energy diagrams have been central tools for chemistry teaching and research for over 50 years. We present an application, EveRplot, which is accessible by web browser (including mobile devices) and can be used to create energy versus reaction coordinate plots quickly and easily. Through three case studies, we illustrate the use of the…

The literature on U.S. Americanization in Puerto Rico's public schools suggests that "de jure" U.S. Americanization culminated in 1949 when an administrative order made Spanish the official language of instruction. However, the same literature seems to indicate that students continue to experience the impacts of U.S. Americanization…

A computational experiment investigating common organic chemistry mechanisms has been developed and implemented in a junior/senior-level physical chemistry laboratory course at two institutions. Students investigated various reactions that proceed via S[subscript N]1, S[subscript N]2, E1, and E2 mechanisms using hybrid Density Functional Theory…

Solution equilibria diagrams are excellent tools for understanding chemical speciation in multireaction chemical systems. They are usually plotted using software packages that efficiently perform advanced calculations, giving the possibility to graphically visualize thermodynamic and composition information. However, this approach frequently…

The purpose of this study was to assess the effectiveness of timetable scheduling that was developed using graph coloring for the class period time tabling. This study presents a study of using graph coloring for effective timetable scheduling at ordinary secondary level, a case study of Dodoma central secondary school in Dodoma city. Algorithms…

Attending to distracting or competing information is typically considered detrimental to learning, but the presence of competing information can also facilitate learning when it is relevant to ongoing task goals. Educational settings often contain contextual elements such as classroom decorations or visual aids to enhance student learning. Despite…
