Enhancement of spatial ability in girls in a single-sex environment through spatial experience and the impact on information seeking. (open access)

Enhancement of spatial ability in girls in a single-sex environment through spatial experience and the impact on information seeking.

The test scores of spatial ability for women lag behind those of men in many spatial tests. On the Mental Rotations Test (MRT), a significant gender gap has existed for over 20 years and continues to exist. High spatial ability has been linked to efficiencies in typical computing tasks including Web and database searching, text editing, and computer programming. The relationships between the components of visuospatial ability and performance are complex. However, research strongly indicates that a connection exists, and further research is necessary to determine the interactions between the variables of environment, genetics, and spatial training. Spatial experience can enhance spatial skills. However, to what extent spatial skills can be enhanced in female adolescents through a spatial curriculum to reduce the gap in scores has not been fully researched, nor has the impact of spatial skill on information seeking. This research project investigated spatial skill in adolescent females by examining (1) the extent to which the intervention of teaching a spatial curriculum in a single-sex setting could improve mental rotation test scores, and (2) the impact of spatial skills on an information seeking task in a single-sex setting. The extent to which a spatial visualization curriculum can improve MRT …

Globally Distributed Agile Teams: An Exploratory Study of the Dimensions Contributing to Successful Team Configuration (open access)

Globally Distributed Agile Teams: An Exploratory Study of the Dimensions Contributing to Successful Team Configuration

Drawing upon configurational theory, work group design research, virtualness concepts, and the software agility literature, the purpose of this study was to provide a starting point for theorizing about the successful configuration of globally distributed agile teams by exploring the dimensions of team structure, virtualness, and agility. Due to the complex nature of this topic, the need to examine the phenomenon within its natural setting, and the limited amount of research that has been conducted in this particular area, this study adopted an embedded multiple-case research design. The primary data collection method consisted of semi-structured interviews involving members of globally distributed agile teams within three U.S. based organizations with members located in distributed sights in multiple countries. Additional data were collected from archival records. Within-case and cross-analysis was conducted using qualitative data analysis software. This study provides a starting point for answering the question of how the configuration of globally distributed agile teams differs from the configuration of other types of globally distributed teams; it synthesizes past research and findings into a comprehensive theoretical framework; it provides a starting point for theorizing about the successful configuration of globally distributed agile teams; it helps practitioners to identify and address the challenges …

Affordances of External Representations in Instructional Design: The Effect of Narrative and Imagery in Learning. (open access)

Affordances of External Representations in Instructional Design: The Effect of Narrative and Imagery in Learning.

Consisting of both theoretical and empirical inquires, this study examines the primary functions of narrative and the relationship between narrative and mental imagery. The study proposes a new framework to interpret semiotic resources. Combining this with the linguistic functional theory of Halliday (1978), a functional method to empirically investigate semiotic representations was also developed. In the empirical inquiry, the study developed a latent construct method to empirically test the effects of narrative in a real learning situation. This study is the first to investigate the functional relationship between narrative and mental imagery, and among the first to suggest a theory and empirically investigate representations of a multimodal nature. The study is also among the first to use latent constructs to investigate the learning experience in a real educational setting. Data were collected from 190 library professionals who enrolled in three sections (two in narrative and one in plain text) of an online course administered through Vista 4.0 and who completed the course and responded to several instruments. Essay data (n = 82 x 2) were analyzed using content analysis based on the narrative analysis framework developed. Quantitative data analysis methods include univariate data analysis, factor analysis, and structural equation modeling …
