abstract: One of the major issues confronting education in Arizona and across the United States has been the consistent low performance of culturally and linguistically diverse (CLD) students in comparison to their peers as evidenced by the disparity of the achievement gap at every level in the educational pipeline. A contributing factor has been the lack of teacher preparation focused on teaching CLD students. Preparation focused on a culturally responsive curriculum about dispositions and pedagogical knowledge and skills as well as field experience placement with CLD students have been previously identified areas to consider when training preservice teachers (PSTs). Therefore, this study examined how a Culturally Responsive and Linguistic Teaching (CRLT) Framework would raise preservice teacher’s critical consciousness about teaching CLD students. The CRLT Framework focused on two specific areas; (a) a culturally responsive curriculum and (b) a team-based service-learning experience. The CRP curriculum included lessons designed to increase PSTs understanding about how their sociolinguist views influenced their pedagogical knowledge about teaching CLD students. In addition, the team-based service-learning approach, as a community of practice, provided experiences for PSTs to apply theory to practice. A mixed method analysis was employed to collect and analyze the quantitative data (surveys) and qualitative data (interviews and photovoice). Results from this study suggested increases in PSTs’ knowledge, self-efficacy, and perceptions of usefulness of CRP in their future practices. The team-based, service-learning component, which was based on a community of practice framework, enhanced the learning experience by allowing students to move from theory to practice and served as an important contributing factor to the overall results. Given the findings of this research study, it appeared that an introductory course focused on a culturally responsive and linguistic teaching influenced PSTs’ dispositions, knowledge, and skills. Thus, providing an introductory course, earlier rather than later, has the potential to change the trajectory of preparing PSTs so they were more prepared to teach CLD students as they continued through their program of study. Results showed effective work with CLD students was about so much more than ‘just good teaching.’ / Dissertation/Thesis / Doctoral Dissertation Educational Leadership and Policy Studies 2019

Τα τελευταία χρόνια παρατηρείται μία μεταρρύθμιση στα Αναλυτικά Προγράμματα Σπουδών των Μαθηματικών, διεθνώς, ως προς την θέση που κατέχουν τα Στοχαστικά Μαθηματικά (Στατιστική και Πιθανότητες) σε αυτά. Στη χώρα μας αυτή η αλλαγή συντελείται με την εισαγωγή του νέου Α.Π.Σ. (2011) των Μαθηματικών για την υποχρεωτική εκπαίδευση, στο οποίο η Στατιστική κατέχει ιδιαίτερη θέση. Για να μπορέσει, όμως, το νέο Α.Π.Σ. να εφαρμοστεί με αποτελεσματικότητα είναι απαραίτητο πρώτα οι δάσκαλοι να έχουν κατανοήσει σε βάθος το αντικείμενο της Στατιστικής που καλούνται να διδάξουν. Με αφορμή την διαπίστωση αυτή, στην παρούσα διατριβή διερευνήθηκαν οι γνώσεις που χρειάζεται να έχουν οι υποψήφιοι δάσκαλοι και αξιολογήθηκαν οι υπάρχουσες γνώσεις τους σε σχέση με την ύλη της Στατιστικής που καλούνται να διδάξουν μετά το πέρας των σπουδών τους αλλά και υπό το πρίσμα του Στατιστικού Γραμματισμού. Για τον προσδιορισμό των γνώσεων που χρειάζονται να έχουν οι υποψήφιοι δάσκαλοι αναλύθηκαν τα Α.Π.Σ. (Ελλάδας και χωρών του εξωτερικού) και τα σχολικά εγχειρίδια ως προς τη θέση της Στατιστικής σε αυτά. Επιπλέον, διερευνήθηκαν οι Μεγάλες Ιδέες της Στατιστικής μέσω της βιβλιογραφικής ανασκόπησης. Η διαμόρφωση του θεωρητικού πλαισίου στηρίχτηκε στο πώς ορίζεται η γνώση για την διδασκαλία των Μαθηματικών αλλά και ειδικότερα της Στατιστικής, στην έννοια του Στατιστικού Γραμματισμού και στον διαχωρισμό της γνώσης στην εννοιολογική και διαδικαστική διάσταση της. Η μεθοδολογική προσέγγιση που χρησιμοποιήθηκε εντάσσεται στην ποιοτική έρευνα και βασίστηκε σε έναν αναδυόμενο ερευνητικό σχεδιασμό. Για τους σκοπούς της έρευνας κατασκευάστηκε και διανεμήθηκε ένα ερωτηματολόγιο με ερωτήσεις ανοικτού τύπου σε 100 υποψήφιους δασκάλους και στη συνέχεια διενεργήθηκαν συνεντεύξεις με 15 από αυτούς. Για την ανάλυση των απαντήσεων των συμμετεχόντων χρησιμοποιήθηκε η ταξινομία SOLO (Biggs & Collis, 1982, 1991) σε συνδυασμό με μία μέθοδο αξιολόγησης που έχει προταθεί από την Garfield (1993). Μέσω των αποτελεσμάτων της παρούσας έρευνας αναδείχθηκε ότι η στατιστική γνώση του περιεχομένου των συμμετεχόντων δεν ήταν επαρκής ενώ η παιδαγωγική γνώση του περιεχομένου τους ήταν ελλιπής. Συγκεκριμένα, οι συμμετέχοντες αντιμετώπισαν δυσκολία στο να αξιολογήσουν τις λανθασμένες απαντήσεις μαθητών και να προτείνουν την ενδεδειγμένη λύση. Επιπροσθέτως, σε αρκετές περιπτώσεις επαναλάμβαναν τα λάθη και τις παρανοήσεις των μαθητών. Προέκυψε, επομένως, ότι δεν είναι σε θέση να αναπτύξουν τον Στατιστικό Γραμματισμό στους μελλοντικούς μαθητές τους. Έχοντας ως βάση αυτά τα αποτελέσματα διατυπώθηκε μία ολοκληρωμένη πρόταση εισαγωγής, στα Παιδαγωγικά Τμήματα Δημοτικής Εκπαίδευσης, μαθημάτων που το περιεχόμενο τους θα εστιάζει στην μάθηση και την διδασκαλία της Στατιστικής για το Δημοτικό σχολείο. / This thesis explores the knowledge needed for teaching statistics at the elementary (primary) school level. It is a fact, that statistics has a relatively short history in the elementary school curriculum, compared with mathematics. Recent research in statistics education has prompted a worldwide move away from the teaching of statistical skills, towards a deeper understanding of statistical notions aiming to the statistical literacy of students and subsequently adults. The new nationally mandated curriculum of Greece reflects this move. Consequently, little is known about the knowledge needed to teach statistics effectively. An analytic study of the current literature, including national standards and school textbooks, was conducted to identify the important aspects of statistical knowledge for teaching. Ideas from three contemporary areas of research, namely teacher knowledge (content and pedagogical) in relation to mathematics and statistics, statistical literacy and procedural and conceptual knowledge are incorporated in a framework for exploring knowledge for teaching statistics and for assessing this kind of knowledge. The study’s methodological approach is based on an emergent research design. A written assessment instrument was developed and administered to a sample of 100 prospective elementary school teachers. The purpose of the instrument was to gather data in order to describe teachers’ conceptions for teaching statistics at the level of elementary school. A subset of the sample (n = 15) was interviewed to provide deeper insight into their conceptions and to assure reliability of the instrument. The data produced in response to the written item were examined in light of the Structure of the Observed Learning Outcome (SOLO) taxonomy (Biggs & Collis, 1982, 1991) and a scoring method offered by Garfield (1993). The results of this study indicate that prospective elementary school teachers may not be prepared to teach statistics at the level of depth that is needed according to the new curriculum. Their statistical content knowledge is not enough while their pedagogical content knowledge is limited. In particular, participants showed difficulties in judging students’ answers and identifying students’ misconceptions. There are several implications that are drawn from the results including the importance of a statistics course during teacher preparation programs and careful consideration during the creation of curricular materials, like new textbooks.

Developing professional expertise of prospective teachers not only in terms of theoretical knowledge but also in terms of competencies of designing challenging and cognitively activating learning opportunities in the mathematics classroom is certainly one of the key aims of internship phases in pre-service mathematics teacher training. As mathematics-related theoretical contents of teacher training and practice-related learning opportunities of school internships are not always linked in an optimal way, this paper aims at discussing a model of an intensive internship phase combined with a triple coaching approach partly integrated in a course accompanying the internship phase.

H πολυπολιτισμικότητα, τόσο στην κοινωνία όσο και στην εκπαίδευση, είναι μία πραγματικότητα στον 21ο αιώνα και σημαντικές αλλαγές έχουν γίνει στη διάρθρωση του εκπαιδευτικού μας συστήματος ώστε να ανταποκριθεί στις προκλήσεις της πολυπολιτισμικής, πια, ελληνικής τάξης. Σημαντικές αλλαγές έχουν γίνει και στην εκπαίδευση των μελλοντικών δασκάλων. Καθώς οι εκπαιδευτικοί αποτελούν κινητήριο δύναμη του εκπαιδευτικού συστήματος ο εμπλουτισμός των Προγραμμάτων Σπουδών των Παιδαγωγικών Τμημάτων Δημοτικής Εκπαίδευσης. Mε γνωστικά αντικείμενα συναφή με τη διαπολιτισμικότητα θεωρήθηκε ότι θα δώσει στους μελλοντικούς δασκάλους τις δεξιότητες, τη γνώση και τις πρακτικές που χρειάζονται για να κατανοήσουν τη δική τους ταυτότητα καθώς και την ταυτότητα των διαφοροποιημένων μαθητών τους με σκοπό μια αποτελεσματική διδασκαλία για όλους τους μαθητές. Η παρούσα εργασία μελετάει τη συμβολή του Προγράμματος Σπουδών στη διαπολιτισμική επάρκεια και ετοιμότητα των μελλοντικών δασκάλων, αποφοίτων του Παιδαγωγικού Τμήματος Δημοτικής Εκπαίδευσης Πατρών. Εξετάζει την πορεία της διαπολιτισμικής εκπαίδευσης στο Πρόγραμμα Σπουδών του Παιδαγωγικού Τμήματος Δημοτικής Εκπαίδευσης Πατρών, τις απόψεις των μελλοντικών δασκάλων πάνω σε διάφορα θέματα που σχετίζονται με τη διαπολιτισμική επάρκεια και ετοιμότητα καθώς και τις απόψεις τους σε θέματα που σχετίζονται με την ύπαρξη αλλά και τον τρόπο εργασίας με αλλόγλωσσους μαθητές. Η συλλογή δεδομένων έγινε με τη χρήση ερωτηματολογίου που δόθηκε σε τεταρτοετής φοιτητές κατά τη διάρκεια των τελευταίων πρακτικών ασκήσεων. Η ανάλυση των αποτελεσμάτων έδειξε ότι ο περαιτέρω εμπλουτισμός του Προγράμματος Σπουδών των δασκάλων τόσο για την απόκτηση θεωρητικών γνώσεων όσο και για την απόκτηση διδακτικών δεξιοτήτων πάνω στη διαπολιτισμική εκπαίδευση είναι αναγκαίος. / Multiculturalism, not only in society but also in education, is a reality in the 21st century and important changes have become in the structure of our educational system in order to corresponds to the challenges of the multicultural Greek classroom. Important changes have also taken place in the education of pre-service teachers While teachers have an important role in the educational system, the enrichment of the undergraduate educational programmes of studies in Greek University Departments of Elementary Education with subjects related to intercultural education is seen as affording pre-service teachers with skills, knowledge and practices needed to understand their own identity as well as the identity of their diverse students with the aim of an effective teaching and learning for all students. This thesis seeks to set out how the undergraduate programme affects the intercultural competence and readiness of pre-service teachers, who will graduate from the Department of Elementary Education in University of Patras. It looks at the development of intercultural education in the undergraduate educational programme and examines the opinions of pre-service teachers about issues related to intercultural competence and readiness. It also focuses on how they feel about working in a multicultural class. The questionnaire was given to students who were in the last year of their studies during their supervised teaching practice at schools. The analysis of the results showed that further enrichment of the educational programme of pre-service teachers in theoretical knowledge and practical experience in intercultural education is necessary.

Esta pesquisa foi realizada em um Instituto Federal de Educação, Ciência e Tecnologia e dedicou-se ao estudo de alguns conceitos de Física Quântica na formação de professores de Física, sob a perspectiva do referencial sociocultural, tendo o foco dirigido à complementaridade de segundo tipo, uma das teses da interpretação de Copenhagen, e ao emaranhamento quântico. O marco teóricometodológico adotado foi a teoria da mediação de Vygotsky e a filosofia translinguística de Bakhtin. Foram realizados três estudos qualitativos com o objetivo de investigar quais são os significados socialmente construídos sobre conceitos de Física Quântica por professores de Física em formação, sendo um estudo piloto e duas intervenções didáticas junto a uma disciplina de Física Moderna e Contemporânea em nível de graduação. As atividades de ensino foram conduzidas a partir de exposições teóricas e simulação computacional com o Interferômetro Virtual de Mach-Zehnder, orientada por roteiros exploratórios. A partir do estudo dos fenômenos da interferência e emaranhamento quânticos nesse dispositivo semiótico, buscou-se compreender em que medida as ações mediadas pelo uso do software como recurso didático atuaram no sentido de promover entre os professores uma construção conceitual colaborativa sobre esses conceitos da Física Quântica. A análise do discurso, fundamentada em conceitos bakhtinianos, possibilitou uma melhor compreensão sobre o processo de construção de conceitos culturalmente válidos acerca da interferência quântica, da complementaridade e do emaranhamento. No contexto explorado, verificamos que se estabeleceu o dilema da manutenção de visões antagônicas, o que pode ser evidenciado a partir dos modelos explicativos elaborados pelos estudantes. Para aqueles que atribuíram um caráter corpuscular aos fótons, os fenômenos intermediários permanecem como um conflito ainda não resolvido, enquanto para os demais a complementaridade onda-partícula passou a compor um nova classe de conceitos. A noção de não-localidade, necessária para compreender o emaranhamento quântico, não foi reconhecida pelos estudantes, evidenciando a forte presença de noções clássicas nos modelos explicativos utilizados na tentativa de obter uma explicação plausível para o fenômeno. / The research presented in this thesis was developed in a Federal Institute of Education, Science and Technology is directed to research about an approach of the some foundations of Quantum Physics in pre-service teachers’ training, based on the sociocultural perspective and this work focuses on the second kind of complementarity, one of the thesis of the Copenhagen interpretation, and the quantum entanglement. The theoretical and methodological framework adopted in this research is the Vygotsky’s theory of mediation and Bakhtin’s translinguistics philosophy. Three qualitative researches were performed in order to investigate which are the socially constructed meanings on QP foundations in the context of pre-service teachers’ training: one in an introductory course with physics teachers and two along a didactic intervention during a pre-service teachers’ training course on Modern and Contemporary Physics. The teaching activities were conducted mediated by theoretical lectures and computer simulation using the Virtual Mach- Zehnder Interferometer, conducted by the exploratory guide. From the study of interference phenomena and quantum entanglement in this semiotic tool, one tries to understand how the pupils actions are mediated by the software in the sense of promoting a collaborative conceptual construction among teachers about these foundations of QP. Discourse analysis grounded on Bakhtin’s concepts allowed us to evaluate the potentialities of the software and a better understanding of the process of conceptual construction that are culturally valid about quantum interference, complementarity and entanglement. In this context we perceive that was created the dilemma of maintaining competing visions, which can be evidenced from the explanatory models designed by the students. For the students that admitted a corpuscular character to photons so that intermediate phenomena remain as a unresolved cognitive conflict, while for others the wave - particle complementarity has became a new class of concepts. The non-locality notion, pre-requisite to understand the quantum entanglement, wasn’t learned by the students, demonstrating the strong presence of classical notions in explanatory models used to obtain a plausible explanation for the phenomenon.

Os Parâmetros Curriculares Nacionais do Ensino Médio, também, orientam que a evolução biológica seja um conceito unficador da biologia, uma vez que, a compreensão da teoria evolutiva pode se interligar a outros conceitos biológicos e, assim, propiciar um ensino menos fragmentado. Diversas pesquisas apontam que os alunos tem dificuldades de compreensão ou aceitação do conceito de evolução. Uma das razões que contribuem para esta dificuldade de compreensão dos históricos presentes nos livros didáticos. Sendo assim, objetivou-se investigar como a inserção de uma discussão epistemológica sobre o conceito de evolução biológica pode contribuir para a aprendizagem de alunos de graduação de licenciatura em ciências biológicas. Para esta dissertação, os instrumentos de pesquisa utilizados foram os questionários, entrevistas semi-estruturadas, e discussões em grupos focais sobre os temas propostos, nas quais questões gerais foram focadas em três eixos: Evolução, História da Biologia e Ensino. Após análise coleta inicial foi possível criar categorias que permitiram agrupar resposta com padrões de explicação similares. Em seguida foram feitas intervenção didáticas, utilizando-se um material didático, organizado pelos autores desta pesquisa, contendo textos da História e Filosofia da Biologia sobre o conceito de evolução biológica. A partir da coleta final pôde-se, então, fazer uma análise comparativa dos dados iniciais, com a finalidade de se observar quais e como os objetivos propostos foram atendidos com a intervenção didática.

The National Curricular Parameters of High School, also, suggest that the biological evolution is a unifying concept of biology, because, understanding of the evaluative theory can establish a connection with other biological concepts and thus promote a less fragmented education. Many researches point that the pupils have difficulties to understand or accept of evolution, being one of reasons that contribute to this difficulty of understanding of related concepts to the theory of evolution, appertain to the misconceptions present in textbooks. Wherefore, it was aimed to investigate as an insertion of an epistemological discussion on the concept of biological evolution can contribute to learning of students in pre-service teachers' education in biology's graduation. For this dissertation, it was used questionnaire, semi-structuralized interviews, and discussion in focal groups about considered subjects, which general questions had been concentrated in three axles: Evolution, History of Biology and Education. After initial analysis of the data, it was possible to create categories that allowed the group to give answers with similar explanations standard. After they were made dicactic intervention, using a didactic textbook organized by the authors of this research, it having texts of History and Philosophy of Biology about the concept of biological evolution. From the finals data a comparative analysis of the initial data could be made, with purpose of observing which and how they considered aims had been reached with the didactic intervention.
