This thesis investigates the process of communication between a person who has in-depth and technical knowledge about certain items and a person who has very broad and non-technical knowledge. For example, a doctor has detailed knowledge about all types of diseases, whereas, an ordinary person only knows a few common type of them. People use categories to communicate; the language, which is used in communication, is categorical. In addition, knowledge can be expressed in categories, and the categories are formed based on the knowledge that the person has. If the person has a superficial knowledge about a specific subject, he then creates superficial categories; whereas, if he has in-depth knowledge, he creates detailed and technical categories. The communication process between a person with technical categories of knowledge and a person with non-technical categories can be presented by the way that they match their categories. Shared cognition is formed if a category exists or is formed that is completely understandable for both parties. Literature on communication studies have never focused on the way that people with categorical knowledge communicate; therefore, an exploratory study is designed to figure out the process of communication when people have categorical knowledge. The task that is used in this study simulates the situation that two persons with categorical knowledge are communicating. The results of this thesis introduce a new representation for the communication process between a technical and non-technical communicators and the way that shared cognition can be analyzed.

Multiteam systems are an integral part of our daily lives. We witness these entities in natural disaster responses teams, such as the PB Oil Spill and Hurricane Katrina, governmental agencies, such as the CIA and FBI, working behind the scenes to preemptively disarm terrorist attacks, within branches of the Armed Forces, within our organizations, and in science teams aiming to find a cure for cancer (Goodwin, Essens, & Smith, 2012; Marks & Luvison, 2012). Two key features of the collaborative efforts of multiteam systems are the exchange of information both within and across component team boundaries as well as the virtual tools employed to transfer information between teams (Keyton, Ford, & Smith, 2012; Zaccaro, Marks, & DeChurch, 2012). The goal of this dissertation was to shed light on enabling the effectiveness of multiteam systems. One means of targeting this concern was to provide insight on the underpinnings of MTS mechanism and how they evolve. The past 20 years of research on teams supports the central role of motivational and affective states (Kozlowski & Ilgen, 2006; and Mathieu, Maynard, Rapp, & Gibson, 2008) as critical drivers of performance. Therefore it was my interest to understand how these critical team mechanisms unravel at the multiteam system level and understanding how they influence the development of other important multiteam system processes and emergent states. Specifically, this dissertation focused on the influence motivational and affective emergent states (such as multiteam efficacy and multiteam trust) have on shaping behavioral processes (such as information sharing-unique and open) and cognitive emergent states (such as Transactive memory systems and shared mental models). Findings from iv this dissertation suggest that multiteam efficacy is a driver of open information sharing in multiteam systems and both types of cognitive emergent states (transactive memory systems and shared mental models). Multiteam trust was also found to be a critical driver of open information sharing and the cognitive emergent state transactive memory systems. Understanding that these mechanisms do not evolve in isolation, it was my interest to study them under a growing contextual state that is continuously infiltrating our work lives today, under virtual collaboration. This dissertation sought to uncover how the use of distinct forms of virtual tools, media rich tools and media retrievability tools, enable multiteam systems to develop needed behavioral processes and cognitive emergent states. Findings suggest that the use of media retrievability tools interacted with the task mental models in promoting the exchange of unique information both between and within component teams of a multiteam system. The implications of these findings are twofold. First, since both motivational and affective emergent states of members within multiteam systems are critical drivers of behavioral processes, cognitive emergent states, and in turnmultiteam system performance; future research should explore how we can diagnose as well as target the development of multiteam system level efficacy and trust. Second, the virtual communication tools that providemultiteam systems members the ability to review discussed materials at a later point in time are critical for sharing information both within and across component teams depending on the level of shared cognition that multiteam system members possess of the task.Therefore the ability to encourage the use and provide such tools for collaborative purposes is beneficial for the successful collaboration of multiteam systems.

The purpose of this intrinsic case study was to show how Expert Team Theory can explain the application of goal orientated rehearsal strategies which were designed for this study for an ad hoc ensemble at the School of Music of the North-West University, Potchefstroom, South Africa. The case study was considered as the most suitable research method to investigate the ways in which goal-orientated rehearsal strategies influence dynamics during rehearsals of a new music ensemble, and the experiences by the members of their interaction, because this approach allowed me to investigate these strategies in a real world environment. This study was born out of an interest in rehearsal strategies and in different ways to structure music rehearsals. The characteristics of a new music ensemble determined the use of Expert Team Theory as the theoretical basis for the design of the goalorientated rehearsal strategies. These characteristics correspond well with that of an expert team as “a set of interdependent team members, each of whom possesses unique and expert-level knowledge, skills, and experience related to task performance, and who adapt, coordinate, and cooperate as a team, thereby producing sustainable and repeatable team functioning at superior or at least nearoptimal levels of performance” (Salas et al., 2006:439-440). Based on interviews with the participants and the observations of video recordings of the rehearsals, the results show that interpreting the data through the theoretical lens of Expert Team Theory enabled me to explain the rehearsal process as a dynamic confluence of experiences created through the interaction of the ensemble members who grew through increasing cooperation and coordination to resemble an expert team. Their sense of collectiveness and their trust coupled with strong leadership allowed the success of the strategy of prebrief-performance-debrief. The ensemble developed progressively clearer shared mental models and understandings of roles and responsibilities. A clear, valued and shared vision helped them to manage and optimize performance outcomes. The findings are also interrogated in terms of cooperative learning to further explain the web-like way in which different themes developed. This led to a discussion of the limitations of this study and suggestions for further research. / MA (Performance), North-West University, Potchefstroom Campus, 2015

Abstract This study focused on enriching collaborative learning through pedagogically scripted multiplayer games. Collaborative learning was examined in the synchronous discussions of small group problem-solving activities in face-to-face and virtual game settings. The theoretical approach is socio-cognitive and builds on the contextual and situated nature of learning. Interaction between group members in social situations is a key mechanism fostering students’ collaborative learning. In the field of Computer-Supported Collaborative Learning the underlying aim is to stimulate and structure socially shared construction of knowledge and development of shared understanding among the collaborators. This thesis consisted of three empirical studies. The first study focused on analysing the macro-level elements of teacher education students’ face-to-face discussions in a context of an international web-based course. The focus of the second and third empirical studies was on how distributed collaboration can be enriched by scripting multiplayer game environments. The game environments were developed and tailored as part of the empirical studies. The main aim was to analyse small-group micro-level interactions and activities taking place during the game. Moreover, the particulars of a 3D voice-enhanced multiplayer game context for small-group shared collaborative activities were investigated. The focus of the last empirical study was on aspects of collaborative game activity and shared problem solving described from the perspective of individual players. The results indicated that the synchronous small-group discussions, on the macro-level, consisted of explaining, sharing knowledge, providing critiques, reflection, and joint engagement. The micro-level elements of the players’ discussions during the game were questions, content statements, social statements, suggestions, instructions or orders, encouragements, and responses. Both macro and micro level elements varied in random order during the discussion, forming a base for small-group discussion and joint problem-solving efforts. Not all problem-solving situations in the game data were shared, indicating that if shared collaborative activity was pursued, the scripting of the game tasks must require equal participation and teamwork during the game. The 3D game environment created a strong shared context for the distributed groups by engaging the players and reinforcing individual participation through the avatar activity. The findings of this thesis contribute to the future development of serious games and highlight the potential of multiplayer games as tools for supporting the social aspects of distributed teamwork. / Tiivistelmä Väitöstutkimus tarkastelee yhteisöllisen oppimisen rikastamista pedagogisesti vaiheistettujen virtuaalipeliympäristöjen avulla. Tutkimuksessa on analysoitu pienryhmien sosiaalista vuorovaikutusta luokkahuonekeskusteluissa ja puhevälitteisissä peliympäristöissä. Teoreettisesti tutkimus pohjautuu sosiokognitiiviseen käsitykseen oppimisesta, jonka mukaan sosiaaliset tilanteet voivat käynnistää yksilöissä oppimisen kannalta keskeisiä mekanismeja, kuten esimerkiksi selittämistä ja tiedon jakamista. Yhteisöllisen oppimisen ytimeksi katsotaan jaetun ymmärryksen rakentaminen sosiaalisessa vuorovaikutuksessa, mitä tietokoneavusteisen yhteisöllisen oppimisen tutkimuslinjassa pyritään tukemaan vaiheistamalla oppimisympäristöjä. Tutkimus koostuu kolmesta eri osatutkimuksesta, joista ensimmäisessä analysoitiin korkeakouluopiskelijoiden pienryhmäkeskustelua luokkahuonetilanteessa. Lähitapaamiset toimivat kurssilla hajautetun kansainvälisen verkkotyöskentelyn tukena. Toisessa osatutkimuksessa tarkasteltiin, voiko hajautettua yhteisöllistä oppimista rikastaa puhevälitteisen monenpelaajan peliympäristön avulla. Pelin tehtävät suunniteltiin ja vaiheistettiin yhteisöllistä toimintaa vaativiksi sekä jaetun ymmärryksen rakentamista tukeviksi. Analyysi keskittyi korkeakouluopiskelijoiden pelinaikaisen keskustelun ja ongelmanratkaisutilanteiden tarkasteluun. Kolmannen osatutkimuksen tavoitteena oli tutkia, mitä osatekijöitä työelämäkontekstista tulleet osallistujat joutuivat hallitsemaan puhevälitteisessä monenpelaajan pelissä. Tutkimusten video- ja haastatteluaineistot analysoitiin laadullisen sisällönanalyysin menetelmin. Tutkimustulokset osoittivat, että pienryhmän vuorovaikutus koostuu makrotasolla mm. selittämisestä, tiedon jakamisesta ja reflektoinnista. Mikrotasolla mm. kysymykset, toteamukset, auttaminen ja ehdottaminen vaihtelivat puheenvuoroittain ja muodostivat yhteisen toiminnan pohjan pienryhmän pelaamisessa. Kaikki ongelmanratkaisutilanteet pelin aikana eivät kuitenkaan olleet jaettuja. Tulokset osoittavat, että kun tavoitellaan aidosti yhteisöllisiä tilanteita, pelin tehtävät täytyy vaiheistaa niin, että ne vaativat kaikkien osallistumista ja pitävät ryhmää virtuaalisesti yhdessä. Tässä tutkimuksessa käytetyt peliympäristöt muodostivat hajautetuille ryhmille vahvan jaetun tilan ja virtuaalisten ihmishahmojen eli avatarien kautta osallistuminen vahvisti yksilöiden toimijuutta pienryhmän osana. Tuloksia voidaan hyödyntää hajautetun tiimityön kontekstissa sekä käyttää tukena tulevaisuuden virtuaalisten tiimipelien suunnittelussa.

Esta pesquisa tem como objetivo investigar a prática de formulação na fala-em-interação de uma sala de aula de inglês como língua adicional na Educação de Jovens e Adultos (EJA). Os conceitos teóricos e a fundamentação metodológica estão embasados na Análise da Conversa Etnometodológica (ACE). O conjunto de dados se constitui de cerca de 14 horas de gravações audiovisuais realizadas em uma escola estadual situada na periferia geográfica e econômica de Porto Alegre. Houve trabalho colaborativo entre a pesquisadora e a professora de inglês da escola que produziram em conjunto o material didático utilizado nas aulas. A análise dos dados evidenciou que a prática da formulação foi uma prática recorrente utilizada pela professora para conduzir a aula. As formulações auxiliaram no destaque e na exposição da construção de conhecimento realizada no grupo, bem como na checagem de entendimento e na resolução dos problemas de intersubjetividade através do reparo em terceira posição. Também foi observada e analisada a relação entre a prática de formular e a cognição socialmente compartilhada e a relação das formulações com o ensino-aprendizagem. A análise detalhada das interações revelou o engajamento dos participantes com a construção conjunta de conhecimento, revelou também essa construção sendo tornada explícita por eles na interação. / This research aims at investigating the formulating practice in talk-in-interaction at an young and adults’ (EJA) classroom in which English is taught as an additional language. The theoretical and methodological concept underlying the research is the Conversation Analysis (CA). The research collection is comprised of a fourteen-hour video recording of interactions carried out at a state school situated in Porto Alegre geographic and economics’ suburb. There was a collaborative work between the researcher and the school English teacher, they elaborated the didactic material used in class. The data analysis provided evidence that the formulating practice was a recurrent practice used by the teacher to conduct the class. The formulations helped in pointing out and explicit the construction of knowledge which was being done by the group, to check understanding and to solve intersubjectivity problems by the third position repair. It was also observed and analyzed the relation between the formulating practice and the socially shared cognition and the relation between formulation and learning-teaching. A detailed analysis of the interactions reveals the participants’ engagement to the joint construction of knowledge and it also shown this construction being made explicit by them in the course of their interaction.

The main goal of this study was to identify some determinants of collective efficacy in small groups. A multilevel approach was used to posit hypotheses and research questions relating individual and shared beliefs of collective efficacy to collective cognition activities, task interdependence, self-efficacy for group work, and collective orientation. A two-phase longitudinal design was employed. The sample comprised 270 university students, enrolled in seven courses and involved in 86 work groups in both phases of the study. All groups were required to perform interdependent academic tasks. The results of multiple regression analysis of aggregated variables provided some evidence that the more group members perceived themselves to be interdependent in the early stages of group work and assigned their tasks interdependently during group processes, the more likely they developed high collective efficacy in the final stages of group work. Collective efficacy was also related to the group average of self-efficacy for group work when task interdependence was high. Multilevel analysis was also used. These results showed that variation at the individual level was considerable, and there was significant but relatively little variation at the group level, with small effect sizes, for a few variables including collective efficacy. Structural equation modelling was used to confirm the theoretical framework at the individual level after accounting for group level variation. The results suggested that integration and constructive evaluation of ideas during group processes and self-efficacy for group work may have been determinants of collective efficacy at the individual level. Moreover, collective efficacy at the individual level was related to an interdependent perception of self in relation to other group members. The results suggest that helping group members learn how to evaluate and integrate each other???s ideas during group activities, and perceive themselves to be interdependent may enhance group capabilities for performing tasks. In addition, improving students??? self-efficacy for group work was identified as a key factor, as it may enhance a sense of interdependence among group members, improve the extent to which group members participate in integrating and evaluating ideas, and increase the whole group???s capabilities for performing tasks.
