<p>This report presents the use of questions by both teachers and students in chemistry class. Both students and teachers have been observed during 24 lessons, both theoretical and practical. In addition, interviews have been made with the teachers and the students have answered a questionnaire. The result show that a high number of questions are asked, more than one per minute and that both teachers and students ask the same amount of questions. This contradicts earlier findings were teachers questions dominate. Another significant finding is that the distribution of questions over time is very similar between teachers and students. In a comparison between different teachers the conclusions can be drawn that the amount of questions asked in a classroom correlates more to the specific teacher than any other factor. This study also shows that both teachers and students are satisfied with the dialog and that the socio-cultural theories about dialogue base teaching have been assimilated into the Swedish classroom.</p>

This study takes a particular look at mathematics teacher education communities of practice (CoPs) in order to provide rich descriptions of the CoPs and make claims about its relation/in relation to teacher preparation and particularly the preparation of preservice teachers for teaching mathematics in multilingual classrooms. The three dimensions of communities of practice proposed by Wenger (mutual engagement, shared repertoire and joint enterprise) were used in conjunction with Mortimer and Scott’s notion of meaning making as a dialogic process as a theoretical lens to gain an entry into the nature of communities of practice in pre-service mathematics teacher education classrooms. Data was collected through pre-observation interviews of 12 teacher educators at four Universities in one Province in South Africa in Phase One of the study. A methodological approach based on Wenger’s CoP theory and Mortimer and Scott’s dialogic process was developed and used to analyse classroom observation videos of four of these teacher educators’ classroom communities of practice in two universities in Phase Two of the study. Using the privileged practices in the CoPs as points of departure and how these practices shaped and were shaped by other dynamics in the CoPs, the findings emerging from the study indicate that within the multiply layers of teacher education, there is an overarching emphasis given to the acquisition of mathematical content. Nevertheless, the communicative approaches and patterns of discourse used by the different teacher educators opened up different possibilities as far as preparing preservice teachers for teaching (in multilingual classrooms) is concerned. Wenger’s community of practice theory has found applications in different spheres of life and in different organisational and educational settings. Its use to understand and describe mathematics pre-service classrooms is, however, still largely unexplored. A theoretical contribution that this study makes lies in the extension of Wenger’s CoP theory to include dialogic processes. A methodological contribution lies in the development of an organisational language (based on Wenger’s three dimensions of CoP) to characterise pre-service teacher education classrooms.

Theoretically, we are grounded on assumptions of Conceptual Linguistics, whose interest analyzes our cognitive apparatus in correlation with our socio-cultural and bodies experiences. We intend to check how is the process of meaning construction and integration of various cognitive domains that are activated during the reading activity. That s why, we take the concept of cognitive domains as equivalent to the structures that are stored in our memory from our sociocultural and corporeal experiences and they are stabilized, respectively, through the frames and schemas. The activation of these conceptual domains, as evidenced by our data, supports the assumption that previous knowledge from our inclusion in specific sociocultural contexts, concurrently with the functioning of our sensory-motor system are essential during the construction activity direction. With this research, we still intend to present a proposal confront the expectations of responses produced by students from the activation of frames and schemas with our predictions / Nossa pesquisa tem por meta principal descrever e analisar os processos relacionados ao acionamento de dom?nios conceptuais subjacentes ? compreens?o do Padr?o Discursivo charge por parte dos alunos da terceira s?rie do Ensino M?dio, na Escola Estadual Professor Ant?nio Bas?lio Filho, em Parnamirim. Teoricamente, estamos ancorados nos pressupostos da Lingu?stica Cognitiva, cujo interesse est? em analisar nosso aparato cognitivo em correla??o com as nossas experi?ncias socioculturais e corp?reas. Pretendemos verificar como ocorre o processo de constru??o de sentidos e a integra??o dos diversos dom?nios cognitivos que s?o acionados durante a atividade de leitura. Para isso, tomamos o conceito de dom?nios cognitivos como equivalente ?s estruturas que s?o armazenadas em nossa mem?ria a partir de nossas experi?ncias socioculturais e corp?reas e s?o estabilizam, respectivamente, a partir dos frames e esquemas. O acionamento desses dom?nios conceptuais, evidenciado nos dados sob an?lise, corrobora o pressuposto de que os conhecimentos pr?vios oriundos de nossa inser??o em contextos socioculturais espec?ficos, concomitantemente com o funcionamento de nosso sistema sens?rio-motor, s?o determinantes durante a atividade de constru??o de sentido. Com esta pesquisa, intentamos ainda confrontar as expectativas de respostas produzidas pelos alunos, a partir do acionamento dos frames e esquemas, com as nossas predi??es
