Research on the cognitive style field dependence-independence establishes its influence on learning and students' outcomes across academic disciplines and at all levels of schooling. Field dependent learners generally perform less well than field independent individuals in most instructional environments. The consequences of cognitive style differences have not been thoroughly pursued by geography educators, and field dependent learners are generally disadvantaged. Review of literature suggests that field dependent learners may perform well in hypermedia-based environments configured to support their learning needs. This study presented geography students with a computer program that contained jigsaw puzzles made from maps and randomly varied the type of interactivity available to learners when solving the puzzles. Field dependent learners were expected to solve the puzzles more quickly and accurately when they were able to interact with the jigsaw puzzle. The interactive treatments provided by the program did not improve the performance of field dependent individuals as expected. / Ph. D.

An independent learner is one who actively takes responsibility for his or her own acquisition of knowledge, skills, and expertise. The capacity to self-regulate one's own learning is a necessity for success in higher education. Researchers have found that characteristics of independent learners begin to emerge in young children and continue to develop throughout childhood and adolescence as students grow into self-governing adults. The purpose of this study is to assess students' levels of independent learning attitudes and behaviors and to examine the relationships among parents' actions, family structure, independent learning, and academic achievement. Using a national sample of 10th grade students from the Education Longitudinal Study of 2002, several statistical analyses were performed in order to answer these research questions: 1. How do parents' actions relate to children's independent learning characteristics? 2. How do students' independent learning behaviors and attitudes correlate with their academic achievement? 3. How are parents' actions associated with their children's academic achievement? 4. Are single-parent children less likely to have developed characteristics of independent learning by grade 10 than children living with both of their parents? Exploratory factor analysis was conducted to arrange the available variables into appropriate subscales to be used in the statistical procedures for this study. Canonical correlations were used to measure the magnitude of relationships between three pairs of concepts: parents' actions and students' independent learning; students' independent learning and academic achievement; and parents' actions and students' academic achievement. Structural equation modeling was employed to test the hypothesized model of relationships among parents' actions, students' independent learning behaviors, and academic achievement. Finally, multivariate analysis of variance was used to compare the independent learning scores of students living in four different family structures to determine if a significant difference in the development of independent learning between groups exists. Results suggest actions that parents can take to help their children develop as independent learners and succeed in the academic realm. / Ph. D.

The relationship between teachers' participation in 4MAT learning style training and their perception of teacher efficacy was investigated three ways. Teachers who participated in 4MAT Fundamentals training were surveyed, observed, and interviewed. The Gusky and Passaro (1994) teacher efficacy scale was given to 120, K-12 teachers at 4MAT training sites. The survey was administered three times: before the workshop, immediately after the workshop and one month after the teachers had returned to their classrooms. The scale measured two teacher efficacy factors: (a) internal teacher efficacy -- perception of personal influence and impact on teaching and learning situations; and (b) external teacher efficacy -- perception of the influence and impact of elements that lie outside the classroom on teaching and learning situations. In addition, the teachers at one learning style training site were observed to determine how readily they adopted learning style terminology. Finally, six teachers were interviewed three times each to determine if factors found by Ashton (1984) to be associated with a high level of teacher efficacy were present. Perceptions of internal teacher efficacy increased significantly from pre- to post workshop administrations. After the teachers had been in the classroom for one month, internal teacher efficacy scores were lower than immediately after the workshop but still significantly higher than before the workshop. The training had no significant impact on external teacher efficacy scores. An interaction was found between teachers' level of previous knowledge and the reported gain in internal teacher efficacy. Those teachers with little previous knowledge of learning style theory and methodology showed higher levels of gain in internal teacher efficacy immediately after the workshop and on the one-month follow-up survey. The teachers' discourse during interviews and behavior during the workshops reflected all the elements Ashton outlined as associated with teacher efficacy: a belief in students' potential to learn and develop, awareness of the classroom as a social setting, and use of reflective behavior. These data also suggested that the maintenance of a high level of efficacy was influenced by the support of colleagues, modeling of instructional techniques, and validation of teachers' ideas concerning practice. It was also noted that teachers adapted 4MAT methodology idiosyncratically. These findings suggest that knowledge of learning style theory and practice can be valuable to teachers. It appears that examining the impact of learning style training on teachers' attitudes and behaviors may provide meaningful insights into why interest in learning style concepts continues despite an inconclusive research base. / Ph.

Virtual environments are visually dominant systems. It seems that individuals" visual perception abilities would have an effect on their performance in a virtual environment. One such visual perception ability that seems a logical fit for study in virtual environments is that of disembedding ability. Disembedding ability is one part of a greater psychological construct known as field dependence. This research investigates how the learner characteristic of field dependence affects learning outcomes in virtual environments In order to examine the effect of virtual environments on recall among learners of differing levels of field dependence, the following specific questions and hypotheses were formed: 1) Does the use of virtual environments affect participants" performance in a task of recall? 2) Do participants of different levels of field dependence perform differently on a task of recall when presented with virtual environments versus static images? 3) Do field-dependent participants score higher on a test of recall when presented with a virtual environment? An experimental design using a sample of Virginia Tech students was employed in this study. The analysis consisted of a 2 X 2 factorial design with main effects for two levels of field dependence (field dependent and field independent), two levels of image representation (virtual environment versus static images), and interaction effects between the two factors. The factorial analysis showed no significant difference in recall test scores for the two treatments. Likewise, there was no significant difference in test scores for field dependent participants who received the virtual-environment treatment versus the static-image treatment. However, a significant interaction existed between field dependence and treatment type, favoring the field-independent participants who received the virtual-environment treatment. It can be concluded from this study that virtual environments have no effect on the recall ability of field-dependent learners. Further research might focus on other individual differences, such as spatial ability, that may have an effect on field-dependent learners" strategies for working in a virtual environment. / Ph. D.

The purpose of this study was to examine whether cueing strategies embedded in computer delivered text messages affected the recall and comprehension of students who differed in their field dependent-independent cognitive style orientations. Two hundred thirty-eight undergraduate students of Virginia Tech participated the study, and 219 sets of valid data were used for the statistical analyses. All participants were given the Group Embedded Figures Test to determine their level of field dependence-independence. They were then randomly assigned to one of three treatment groups that varied in their use of cueing strategy. The first treatment group featured computer delivered text messages with color-highlighted-keywords, the second group featured the same textual content with color-highlighted-key-phrases, and the third group was a control group that featured the same content and employed no cueing strategy. Participants were administered two tests following the treatments, one that assessed knowledge of terminology and another that assessed comprehension. A 3 x 3 Analysis of Variance was conducted to explore the main effects for field dependency and cueing strategy and any interaction effect between the two factors. The results showed that field independents outperformed field dependents in all tests. There were no significant differences for the three treatments; the cueing strategies employed in this study had no effect on participants' learning. A significant interaction was seen between field dependency and cueing strategy. However, the results of a one-way ANOVA are unexpected: the cueing strategies employed did not improve field dependents' performance on the assessments and actually hindered the performance of field independents. / Ph.
