Behavior authoring for computer games involves writing behaviors in a programming language and then iteratively refining them by detecting issues with them. The main bottlenecks are a) the effort required to author the behaviors and b) the revision cycle as, for most games, it is practically impossible to write a behavior for the computer game AI in a single attempt. The main problem is that th...

This paper reports an exploratory study on Singapore secondary and primary school students’ perceptions and behaviors on using a variety of Chinese input methods for Chinese composition writing. Significant behavioral patterns were uncovered and mapped into a cognitive process, which are potentially critical to the training of students in inputting Chinese via computers. Due to the cognitive co...

In this study, we investigated the role of student characteristics and behaviors in a longitudinal study over a 50-year timespan (using a large U.S. representative sample of high school students). We addressed the question of whether behaviors in school have any long-lasting effects for one's later life. Specifically, we investigated the role of being a responsible student, interest in school, ...

Young people can be valuable motivational resources for health promotion. A project implemented from 2009 through 2013 in a small American Indian community in northwest Arizona recruited American Indian young people aged 10 to 21 as agents of change for health promotion through radio programming. Thirty-seven participants were recruited and trained in broadcasting and creative writing technique...

The capability of placing “comments” on the posts makes the blogspaces rather a complex environment. One of the interesting phenomena in blogspace is “blogger failure” when a blogger stops writing after a certain amount of time and will not return to blogspace for a long time, or when a blogger does not get any comment from her audience. In this paper we illustrate our observation on bloggers f...

This paper explores the annotation and classification of students’ revision behaviors in argumentative writing. A sentence-level revision schema is proposed to capture why and how students make revisions. Based on the proposed schema, a small corpus of student essays and revisions was annotated. Studies show that manual annotation is reliable with the schema and the annotated information helpfu...

A fuzzy controller design is performed for a three joint robot leg in protraction phase. The aim is to develop a controller to carry the tip point to any given destination. The design is based on the inspirations derived from optimal behaviors of the leg. The optimal trajectories are obtained by using optimization methods utilizing “numerical gradient” and “optimal control” successively. Separa...

Scripting custom content for computer role-playing games requires the designer to tell a story by writing small fragments of computer code distributed among the characters, props, and locations of the game world. The main challenge of these games is to create believable motivations and behaviors for the dozens or even hundreds of characters and rooms with which the player may interact. We prese...
