With the final objective of using computational and chemometrics tools in the chemistry studies, this paper shows the methodology and interpretation of the Principal Component Analysis (PCA) using pollution data from different cities. This paper describes how students can obtain data on air quality and process such data for additional information…

One of the most promising avenues of research in computer-assisted language learning is the potential for language learners to make use of language corpora. However, using a corpus requires use of a corpus tool as an interface, typically a concordancer. How such a tool can be made most accessible to learners is an important issue. Specifically,…

The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load, and intrinsic motivation in an interactive multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were…

Insignificant consideration in multimedia research has been given to the features that are associated with cognitive functioning in general, and working memory (WM) in particular for preschoolers. As correlational research works discovered a close association between WM and learning achievement, multimedia research works that are tapping into…

Purpose: E-learning is emerging as a potential delivery medium for education and training. This is evident from the increasing number of educational institutions and organizations adopting e-learning. In India, there has been an upsurge in the number of students going for management education. But, before management institutes embark on this…

The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…
