The purpose of this study was to compare receptive language, expressive language, and socialization skills of preschool children who have a history of expressive language delay (ELD) with age mates who have a history of normal language development.

Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

When children grow up in a Christian home they learn fidelity is essential in a relationship. The inconsistency of biblical messages and parental infidelity is identity altering for children. In this study I use autoethnography to explore how my parents’ infidelity collided with religious teachings to shape my identity and influence my interpersonal relationships. I also use narrative interviewing to identity the ways my siblings were affected by the same experience and how such discrepancies in our home influenced their identities. The theory of narrative inheritance (Goodall, 2005) serves to be a source of empowerment as well as a contributing factor to definitions of infidelity. Familial roles are illuminated as I explore how my siblings and I negotiated cognitive dissonance that resulted from the conflicting narratives of Christianity and parental infidelity.

This study analyzes oral recipe sharing practices as they emerge in Southern cooking. Researcher and participants were immersed in cooking recipes together in a qualitative research method that combined interactive interviewing with sensory ethnography. Findings revealed a category of oral recipe sharing practices that is missing from the literature: cooking lessons. This study identified cooking lessons as a distinct recipe sharing practice and worked to further operationalize and concretize such practices in hopes of spurring further research.

This study examines levels of politeness in real time instructor responses to classroom incivility behaviors. Student participants were randomly assigned to view a video of an instructor responding to either passive or active student incivility behaviors in various ways. The responses were based on politeness theory conceptualizations of avoidance, mid-level politeness, or bald on record responses. A 2 (i.e., passive, active student incivility) x 3 (i.e., avoidance, mid-level, or bald on record instructor response) experimental design formed six conditions. High quality video simulations of a classroom environment, portraying one of the six conditions, were created to specifically address these dimensions. Participants took a web based survey and evaluated the instructor with respect to effectiveness, credibility, and impact on student motivation. Results demonstrate students had most positive responses to bald on record instructor responses to active student incivility. When responding to passive student incivility, a less harsh response (i.e., avoidance, mid-level), while not significantly different from a bald on record response, indicate better outcomes. Therefore, in accordance with politeness theory, instructors should consider the level of imposition created by uncivil student behavior when calibrating responses, as student perceptions can be greatly affected. Theoretical and practical considerations as well as avenues for future research are presented.

Modern companies are increasingly relying on groups of individuals to reach organizational goals and objectives, however many organizations struggle to cultivate optimal teams that can maximize performance. Fortunately, existing research has established that group personality composition (GPC), across five dimensions of personality, is a promising indicator of team effectiveness. Additionally, recent advances in technology have enabled groups of humans to form real-time, closed-loop systems that are modeled after natural swarms, like flocks of birds and colonies of bees. These Artificial Swarm Intelligences (ASI) have been shown to amplify performance in a wide range of tasks, from forecasting financial markets to prioritizing conflicting objectives. The present research examines the effects of group personality composition on team performance and investigates the impact of measuring GPC through ASI systems. 541 participants, across 111 groups, were administered a set of well-accepted and vetted psychometric assessments to capture the personality configurations and social sensitivities of teams. While group-level personality averages explained 10% of the variance in team performance, when group personality composition was measured through human swarms, it was able to explain 29% of the variance, representing a 19% amplification in predictive capacity. Finally, a series of machine learning models were applied and trained to predict group effectiveness. Multivariate Linear Regression and Logistic Regression achieved the highest performance exhibiting 0.19 mean squared error and 81.8% classification accuracy.

Millennials are growing within the workforce, but they are becoming difficult to attract and retain for longer than two years at a time. In addition, Millennials have generational-specific values that are different than their predecessors. Identifying and applying these workplace expectations to organizational policies have made it challenging for leaders to appeal to this generation. Millennials desire five aspects from their workplace: work with a purpose, to be their own boss or work for a boss that is a mentor, a collaborative work environment, flexible work schedules, and work-life integration and/or work-life balance. Using a survey research method, this thesis outlines how Millennials appreciate these values in a workplace and, because of this appreciation, employers and recruiters should consider them for attrition and recruitment purposes. This thesis also examines why the assumption that Millennials are job hoppers who would rather work for themselves than an established corporation is unfounded. Finally, this thesis finds that the risk aversion trait Millennials possess affects their potential for decision making regarding their career that this trait can be used by organizations to market communication positions to this generation.

Academic engagement has been found to significantly predict students' future achievement. Among adolescents, the peer context becomes an increasingly important point of socialization and influence on beliefs and behavior, including academic engagement. Previous research suggests that those peers with whom an adolescent spends much of their time significantly predict change in engagement over time (Kindermann, 2007). Bronfenbrenner's ecological systems theory (Bronfenbrenner & Morris, 1998) postulates that exosystem effects (those influencing factors that are not directly connected to individuals) play an important role in development, and social network theorists have suggested that the position one occupies within the greater network is a key factor that determines one's power of influence (Borgatti, 2005). An individual's own position in a network emerges from his or her own connections, as well as from the structures formed by the connections of his or her affiliates (the exosystem). Utilizing an existing dataset, social networks analysis techniques were used to examine how three different forms of centrality (degree, closeness and eigenvector), which are markers for micro- and exo-system effects, relate to classroom engagement and its change over time. Results showed that although centrality in a network is positively related to academic characteristics at one point in time, students who have large numbers of immediate connections (degree centrality) tend to decrease in engagement over time. In contrast, eigenvector centrality showed a positive interaction with peer group influence on change in engagement over time. For those students who had highly interconnected peers the positive effect of peer group engagement was increased.

The purpose of this study was to understand how early adolescents talk about cross-racial and cross-ethnic friendships. Gordon Allport's intergroup contact theory provided the framework for studying the elements needed for inter-racial and inter-ethnic friendship formation. Qualitative data were drawn from four separately recorded peer group conversations. Participants (n=18) were recruited from Parrish Middle School in Salem, Oregon. Patterns that emerged from the data were sorted, categorized and identified according to the tenets of intergroup contact theory or extensions of intergroup contact theory. Analysis also looked at the use of metaphors and storytelling among adolescents. Results showed that while intergroup contact theory tenets of interdependence and common goals can foster cross-ethnic and cross-racial friendships, most students form these friendships through friendship chaining and common interests. Dual racial identity and peer group influence can also be positive factors in cross-racial and cross-ethnic friendship development. Further, storytelling examples by adolescents showed similar techniques to those used by adults. Overall the results from this study support intergroup contact theory as continuing to be a useful conceptual framework for encouraging cross-group relations.

This study focuses on confrontational behavior patterns exhibited by Japanese and U.S. college students in the Portland Metropolitan area. Four questions are addressed: 1) is there a difference Japanese and U.S. confrontation styles? 2) do Japanese use differing confrontation styles depending upon whom they are interacting with? 3) do U.S. individuals use differing confrontation styles depending upon whom they are interacting with? and 4) is there a significant gender difference between Japanese and U.S. confrontation styles? In addition, correlations between the Japanese and U.S. reported confrontation styles and their demographic data are examined.
