The vision of K-12 standards-based mathematics reform embraces a greater emphasis on students’ ability to communicate their understandings of mathematics by utilizing adaptive reasoning (i.e., reflection, explanation, and justification of thinking) through mathematics discourse. However, recent studies suggest that many students lack the socio-cognitive capacity needed to succeed in learner-centered, discussion-intensive mathematics classrooms. A multiple case study design was used to examine the nature of participation in mathematics discourse among two low- and two high-performing sixth grade female students while solving rational number tasks in a standards-based classroom. Data collected through classroom observations, student interviews, and student work samples were analyzed via a multiple-cycle coding process that yielded several important within-case and cross-case findings. Within-case analyses revealed that (a) students’ access to participation was mediated by the degree of space they were afforded and how they attempted to utilize that space, as well as the meaning they were able to construct through providing and listening to explanations; and (b) participation was greatly influenced by peer interactional tendencies that either promoted or impeded productive contributions, as well as teacher interactions that helped to offset some of the problems related to unequal access to participation. Cross-case findings suggested that (a) students’ willingness to contribute to task discussions was related to their goal orientations as well as the degree of social risk perceived with providing incorrect solutions before their peers; and (b) differences between the kinds of peer and teacher interactions that low- and high-performers engaged in were directly related to the types of challenges they faced during discussion of these tasks. An important implication of this study’s findings is that the provision of space and meaning for students to participate equitably in rich mathematics discourse depends greatly on teacher interaction, especially in small-group instructional settings where unequal peer status often leads to unequal peer interactions. Research and practice should continue to focus on addressing ways in which students can learn how to help provide adequate space and meaning in small-group mathematics discussion contexts so that all students involved are allowed access to an optimally rich learning experience.

While the small group discussion is widely used in language classes, there is little empirical research on its efficacy. This research specifically focuses on novice level language students in order to understand the ways that they express agreement and disagreement in group interaction. This study utilizes the methodological framework of Conversation Analysis conducting a micro-analysis of student turn-taking practices and their embodied behavior. This research uncovered the fact that the novice level language learners utilized resources that are not generally considered when investigating agreement and disagreement. Nonverbal actions such as smiles and gaze shifts accomplished affiliative work mitigating disagreement turns. Facial expression, laughter, and gestures were often relied on to compensate for deficits in grammar and lexicon. A second finding of the research was that the students were able to accomplish significantly more as members of a group than they could as individuals. The multi-person context created a framework enabling members to participate. The students demonstrated a high level of collaboration, joining in word searches, successfully constructing collaborated completions, and frequently offering support to each other through receipt tokens, nods, and smiles. They proved to be each other's best resource. Another finding of the study was the importance of basic patterns of turns in effective group discussion. For example, in order for an argumentative sequence to emerge, a third response was expected: Turn 1, the claim; Turn 2, disagreement; and, Turn 3, defense, counterattack, or concession by the first speaker or a different speaker. For less skillful groups where topics were not well developed, only two-part sequences were utilized, not allowing subsequent and related talk to occur. Finally, this study contributes to research on the acquisition of disagreement strategies. Surprisingly, in expressing disagreement, these novice level language students employed a number of different means to express disagreement that were more often associated with advanced learners. For example, they delayed their disagreement turns, and they utilized accounts, exemplification, and elaboration when disagreeing. Though these students were not always able to express themselves fluently, they were nevertheless quite capable in expressing agreement and disagreement in the target language. / English

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.

Culturally responsive instruction refers to the identification of relevant cultural aspects of students’ lives and infusion of these into the curriculum. This instructional approach assumes that a culturally appropriate curriculum can potentially motivate, engage, and lead students to higher rates of achievement. This quasi-experimental study (N=44) investigated the relationship of culturally responsive instruction and the reading comprehension and attitude of struggling urban adolescent readers. The study incorporated the use of culturally responsive instruction using culturally relevant literature (CRL), the Bluford Series Novels, as authentic texts of instruction. Participants were seventh grade reading students at a Title I middle school in South Florida. After a baseline period, two different classes were taught for 8 weeks using different methods. One class formed the experimental group (n=22) and the other class formed the comparison group (n=22). The CRI curriculum for the experimental group embraced the socio-cultural perspective through the use of small discussion groups in which students read and constructed meaning with peers through interaction with the Bluford Series Novels; gave written responses to multiple strategies according to SCRAP – Summarize, Connect, Reflect, Ask Questions, Predict; responded to literal and inferential questions, while at the same time validating their responses through evidence from the text. The Read XL (basal reader) curriculum of the comparison group utilized a traditional form of instruction which incorporated the reading of passages followed by responses to comprehension questions, and teacher-led whole group discussion. The main sources of data were collected from the Gates-MacGinitie Reading Tests, the Florida Assessments for Instruction in Reading (FAIR), and the Rhody Secondary Reading Attitude Assessment. Statistical analyses were performed using Repeated Measures ANOVAs. Findings from the study revealed that the experimental participants’ reading attitudes and FAIR comprehension scores increased when compared to the comparison group. Overall, the results from the study revealed that culturally responsive instruction can potentially foster reading comprehension and a more positive attitude towards reading. However, a replication of this study in other settings with a larger, more randomized sample size and a greater ethnic variation is needed in order to make full generalizations.
