Sarah E. Shaner; Kari L. Stone – Journal of Chemical Education, 2023
A Fourier transform infrared (FTIR) experiment appropriate for an upper-level undergraduate laboratory such as chemical instrumentation is described. Students collect FTIR spectra of four protio-solvents and their deuterated analogues. In addition to qualitatively observing C-H and O-H peaks shift to lower energy upon deuteration, students apply a…

Hansen, S. J. R.; Hu, B.; Riedlova, D.; Kelly, R. M.; Akaygun, S.; Villalta-Cerdas, A. – Chemistry Education Research and Practice, 2019
This mixed method study investigation uses eye tracking and qualitative analysis to investigate the impact of animation variation and visual feedback on the critique of submicroscopic representations of experimental phenomena. Undergraduate general chemistry students first viewed an experimental video of a precipitation or oxidation reduction…

Di Vincenzo, Antonella; Floriano, Michele A. – Journal of Chemical Education, 2019
An application for visualizing the aggregation of structureless atoms is presented. The application allows us to demonstrate on a qualitative basis, as well as by quantitatively monitoring the aggregate surface/volume ratio, that the enhanced reactivity of nanoparticles can be connected with their large specific surface. It is suggested that,…

Goff, Eric E.; Reindl, Katie M.; Johnson, Christina; McClean, Phillip; Offerdahl, Erika G.; Schroeder, Noah L.; White, Alan R. – Biochemistry and Molecular Biology Education, 2017
The use of external representations (ERs) to introduce concepts in undergraduate biology has become increasingly common. Two of the most prevalent are static images and dynamic animations. While previous studies comparing static images and dynamic animations have resulted in somewhat conflicting findings in regards to learning outcomes, the…

Cheon, Jongpil; Chung, Sungwon; Crooks, Steven M.; Song, Jaeki; Kim, Jeakyeong – Educational Technology & Society, 2014
Since the complex and transient information in instructional animations requires more cognitive resources, the segmenting principle has been proposed to reduce cognitive overload by providing smaller chunks with pauses between segments. This study examined the effects of different types of activities during pauses in a segmented animation. Four…

Kelly, Resa M.; Akaygun, Sevil – Journal of Chemical Education, 2016
This article summarizes an investigation into how Flash-based cartoon video tutorials featuring molecular visualizations affect students' mental models of acetic acid and hydrochloric acid solutions and how the acids respond when tested for electrical conductance. Variation theory served as the theoretical framework for examining how students…

Cetin, Ibrahim – Computer Science Education, 2013
The purpose of this study was twofold: to investigate students' concept images about class, object, and their relationship and to help them enhance their learning of these notions with a visualization tool. Fifty-six second-year university students participated in the study. To investigate his/her concept images, the researcher developed a survey…

Jenkinson, Jodie; McGill, Gael – CBE - Life Sciences Education, 2012
Undergraduate biology education provides students with a number of learning challenges. Subject areas that are particularly difficult to understand include protein conformational change and stability, diffusion and random molecular motion, and molecular crowding. In this study, we examined the relative effectiveness of three-dimensional…

Williamson, Vickie M.; Lane, Sarah M.; Gilbreath, Travis; Tasker, Roy; Ashkenazi, Guy; Williamson, Kenneth C.; Macfarlane, Ronald D. – Journal of Chemical Education, 2012
A prior study showed that students best make predictions about the outcome of opening a valve between two flasks containing a fluid or vacuum when they view both a demonstration video and a particulate animation, but the study showed no influence from the order in which these visualizations were used. The purpose of this current research was to…

Paik, Eugene Sam – ProQuest LLC, 2010
A controlled experiment was conducted on the effects of two types of animation--motion and highlighting--on learning. The treatment consisted of a 3.5 minute multimedia presentation that described the workings of a flushing toilet tank. A 2x2 factorial design ({motion, no-motion} x {highlight, no-highlight}) was employed with two dependent…

Narasimhamurthy, Uma; Al Shawkani, Khuloud – Educational Technology, 2010
This article describes a model for teaching Java Programming Language through Dynamic Learning Objects. The design of the learning objects was based on effective learning design principles to help students learn the complex topic of Java Programming. Visualization was also used to facilitate the learning of the concepts. (Contains 1 figure and 2…

Pasko, Alexander; Adzhiev, Valery; Malikova, Evgeniya; Pilyugin, Victor – Journal of Information Technology Education: Innovations in Practice, 2013
Modern education technologies are destined to reflect the realities of a modern digital age. The juxtaposition of real and synthetic (computer-generated) worlds as well as a greater emphasis on visual dimension are especially important characteristics that have to be taken into account in learning and teaching. We describe the ways in which an…

Taylor, M.; Pountney, D.; Malabar, I. – Journal of Further and Higher Education, 2007
Mathematics can be perceived as being a difficult subject to learn due to the conceptual leaps required to understand particular mathematical topics. In some areas of mathematics, part of the difficulty may be associated with applying sufficient imagination to visualize a particular mathematical concept, and applying sufficient visio-spatial…

Edsall, Robert; Wentz, Elizabeth – Journal of Geography in Higher Education, 2007
Two experiments investigating the benefit of computer-based applications in geography education are presented. The computer-based methods employ concepts of visualization, including animation and interactivity, to facilitate active learning. These computer-based methods are compared with physical (i.e. tangible) models, which themselves can be…

Lin-Chih-Lung; Dwyer, Francis – International Journal of Instructional Media, 2004
The purpose of this study was to examine the instructional effectiveness of computer animated instruction, complemented by varied types of instructional strategies (advance organizers and adjunct questions and feedback) on learner achievement of different types of educational objectives. Ninety-three undergraduate students were randomly assigned…
