37. Persuasive Technologies in Education: Improving Motivation to Read and Write for Children.

Abstract

In this paper we present an example of how principles of motivation can be designed into educational software to support students in achieving their goals. The objective of our software was to develop a reading habit in children between 8 and 11 years of age by motivating them to improve their reading and writing skills. By designing activities that integrate Gardner's Multiple Intelligence theory to our software, we were able to motivate children to read while acknowledging individual differences in their learning process. The results on presenting this software to different groups of children from the city and rural environments show how we were able to motivate students to read through the software itself and the activities it proposes, in a way that was credible and connected to the real-world environment children lived in. Our results show the importance of integrating principles from Persuasion such as similarity, tailoring and credibility, together with theories such as Gardner's in educational software to achieve motivation to read and write in children.

Abstract

Chronic stress detrimentally affects animal health and homeostasis, with somatic growth, and thus skeletal muscle, being particularly affected. A detailed understanding of the underlying endocrine and molecular mechanisms of how chronic stress affects skeletal muscle growth remains lacking. To address this issue, the present study assessed primary (plasma cortisol), secondary (key components of the GH/IGF system, muscular proteolytic pathways, and apoptosis), and tertiary (growth performance) stress responses in fine flounder ( Paralichthys adspersus) exposed to crowding chronic stress. Levels of plasma cortisol, glucocorticoid receptor 2 ( gr2), and its target genes ( klf15 and redd1) mRNA increased significantly only at 4 wk of crowding ( P < 0.05). The components of the GH/IGF system, including ligands, receptors, and their signaling pathways, were significantly downregulated at 7 wk of crowding ( P < 0.05). Interestingly, chronic stress upregulated the ubiquitin-proteasome pathway and the intrinsic apoptosis pathways at 4wk ( P < 0.01), whereas autophagy was only significantly activated at 7 wk ( P < 0.05), and meanwhile the ubiquitin-proteasome and the apoptosis pathways returned to control levels. Overall growth was inhibited in fish in the 7-wk chronic stress trial ( P < 0.05). In conclusion, chronic stress directly affects muscle growth and downregulates the GH/IGF system, an action through which muscular catabolic mechanisms are promoted by two different and nonoverlapping proteolytic pathways. These findings provide new information on molecular mechanisms involved in the negative effects that chronic stress has on muscle anabolic/catabolic signaling balance.
