This study is a qualitative case study of collaborative learning in two chamber music ensembles in a public high school orchestra program. Collaborative learning, as applied to chamber music education, is a setting in which musicians engage in a common musical task and are accountable to the other members of the group. Using social constructivism as a conceptual framework, I sought to explore student collaboration within chamber music ensembles through social interaction and the development of creative rehearsal strategies. Attention was directed to the way in which students identified problems and developed rehearsal strategies to solve them. The following research questions guided this study: (1) How do students in the selected chamber music ensembles engage in collaborative learning? (2) What are the learning structures that enable collaboration within each group? (3) How do the students interact with each other in the selected chamber music ensembles? (4) What are the social structures that enable collaborative learning within each group? Using Mediated Discourse Analysis (MDA) I analyzed and interpreted the collaborative learning that occurred in the musical development of these high school chamber musicians. Data collection occurred during one semester of instruction (five months) and included individual interviews, focus group interviews, and observations, which included field-notes and digital video of rehearsals. The research methodology used in this study comprised the “interpretive–descriptive” method and focused on turning the participants’ words and actions into the development of potential themes and implications. My approach used a three-step process to analyze data in which concepts were coded relating to the phenomenon of collaborative and mutual learning as well as sociocultural mediation. In this study, I examined the collaborative learning process among the student participants. My study was further informed by the participants’ perceptions of their own collaborative learning processes. Themes found were learning structures that allowed for collaboration in interpretation and problem solving, and social structures that enabled peer pressure, socialization and a work ethic. Results indicated that when given the opportunity to work in small groups toward pre-determined musical goals, the participants in this study: (1) worked with internal group leaders to identify musical problems and develop creative rehearsal strategies to solve them, (2) used positive and negative peer pressure that created an organic social structure which contributed to team efficacy, and (3) showed a willingness to work harder toward group goals when empowered with the responsibility for their own learning. The results of this study suggest that a collaborative learning environment that includes small groups of heterogeneously mixed students can advance student learning in multiple ways. The traditional teacher centered learning environment may not be the most effective learning environment because it may limit student development in one or more capacities, including decision making and social development. Recognition of the active, purposeful character of human development and respect for the shared understanding (socially distributed knowledge) that enables peers to teach one another ought to shape the music educator’s role and function; to serve as a musical guide, facilitator, and source of social support. Based on the results of this study, it appears that it may be possible to adapt collaborative learning to diverse instructional situations regardless of the heterogeneous makeup of the learning group.

Teachers tend to refrain from using a postcolonial perspective in their teaching of literaturebecause they do not know quite how to approach the task. The purpose of this essay is to remedy such a problem. The argument is built on three concepts: unhomeliness, dual identities and othering. These concepts will first be introduced within a postcolonial context generally and will then be studied more specifically – through close reading – as main themes in Jamaica Kincaid’s novel Lucy. This essay aims to provide a model for educators to implement postcolonial theory in the classroom. Moreover, collaborative learning and dialogue will be presented as key elements in a teaching strategy that encourages teachers totackle the postcolonial perspective didactically.

Student success in chemistry has been linked to a wide range of factors. Some of these factors are familiar, easily quantified measures; colleges typically rely on factors like high school GPA and measures of aptitude to make admission decisions or set course prerequisites. Success in chemistry courses can be linked to these measures, and math aptitude scores in particular are often used as prerequisites for introductory chemistry courses. However, success in chemistry can also be affected by factors like motivation, peer interactions, sense of belonging, and metacognitive skill. Additionally, outcomes in chemistry and other STEM courses like math and physics have been repeatedly found to be inequitable. In Chapter I, background information relevant to the subsequent chapters will be discussed. In Chapter II, group quizzes were implemented as a collaborative learning tool in a large-lecture format first-semester organic chemistry classroom. Chapter III describes a multifaceted scholarship support program for chemistry, physics, and math majors. This program strove to support traditionally underrepresented groups in chemistry through several components, including a team-building course and mentorship. Heavy emphasis was placed on building a peer support network. In Chapter IV, confidence surveys were implemented to encourage student metacognitive monitoring. Student success and confidence were assessed through three scopes: as they pertained to the overall course, by exam, and by individual topic.

Constructing common ground and the associated convergent conceptual change is critical to cooperative work and learning. Convergent conceptual change is achieved as participants in a conversation update common ground through presentations, repairs, and acceptances of utterances. People employ available techniques that utilize the least collaborative effort for current purposes. Although sharing physical co-presence of interlocutors' facial expressions doesn't make grounding more efficient even in more open-ended and less task-focused dialogues, visual co-presence of the addressee's workspace is essential to work-related tasks, such as information transmission and collaborative problem-solving. However, handheld-mediated collaborative activity makes sharing the workspace challenging, especially when we consider that handhelds possess small screens and permit activities of a distributed nature. In a handheld-mediated classroom, a teacher must be able to check students' work for various reasons (e.g., grading, checking whether they are following directions correctly or paying attention) and at various phases of the activity. Gazing into the small screen of a handheld over someone's shoulder is a tricky task at best. The teacher may misread the information on the screen and thus provide incorrect feedback. Another challenge involves the difficulty inherent in latecomers joining the collaborative activity when each student is involved with his or her individual and small screen. This exclusion from joining on-going activity can reduce the chance of student's vicarious and serendipitous learning. Although such events may occur naturally in the learning environment, they become important concerns when one attempts to focus collaborative activities with handheld devices. I therefore created a new handheld network service called "Look," which is designed to facilitate the acquisition of common ground and allow a latecomer to do meaningful monitoring of ongoing conversation about the workspace. I tested empirically the value of this shared physical/virtual context in the task of creating common ground by examining task performance and conversation quality. / Ph. D.

Educators are struggling to meet the ever-increasing challenges of preparing students to meet the demands of a global society. The importance of collaboration and social interaction in online education has been well documented (Berge, 1998; Brown, Collins & Duguid, 1989, Fulford & Zhang, 1993; Gunawardena & McIssac, 2003; Kanuka & Anderson, 1998; Kearsley & Schneiderman, 1999; Sardamalia & Bereiter, 1994). Teachers and instructional designers are struggling to change the academic environment to meet the needs of millennial learners. The purpose of this study is to develop a theory driven process for designing computer-supported collaborative learning in an online environment. A careful analysis of the process for creating collaborative online instruction is conducted and a design strategy for the process is developed. The study provides suggested guidelines for practitioners to create collaborative online instruction. The design procedures emphasize social interaction to allow learners opportunities to explore, discover, and negotiate meaning in an authentic context. Online instruction requires the coupling of multiple areas of expertise to be successful. Although the pedagogical principles are the same, the global implications of "flat world" technology require an important weaving of collaborative interaction, graphic design, and pedagogy. Technology provides the transportation for achieving a collaborative environment; and, quality pedagogical practices provide the GPS (guidance positioning system) to direct collaborative instruction to its ultimate destination–knowledge building. / Ph.

With the rise of big data, it is becoming increasingly important to educate students about data analytics. In particular, students without a strong mathematical background usually have an unenthusiastic attitude towards high-dimensional data and find it challenging to understand relevant complex analytical methods, such as dimension reduction. In this thesis, we present an embodied approach for visual analytics designed to teach students exploring alternative 2D projections of high dimensional data points using weighted multidimensional scaling. We proposed a novel application, <i>Be the Data</i>, to explore the possibilities of using human's embodied resources to learn from high dimensional data. In our system, each student embodies a data point and the position of students in a physical space represents a 2D projection of the high-dimensional data. Students physically moves in a room with respect to others to interact with alternative projections and receive visual feedback. We conducted educational workshops with students inexperienced in relevant data analytical methods. Our findings indicate that the students were able to learn about high-dimensional data and data analysis process despite their low level of knowledge about the complex analytical methods. We also applied the same techniques into social meetings to explain social gatherings and facilitate interactions. / Master of Science
