Language teacher education for intercultural understanding

Over recent decades language teaching and learning has undergone a redefinition of the subject and a rapid change in its methodology. Language programmes can now be delivered in technology‐based environments and communication at an international level can be a daily occurrence. This paper on the one hand analyses how these developments have extended and challenged the traditional roles and responsibilities of language teachers. On the other, it examines to what extent established models of language teacher education acknowledge and address the needs of language teachers today, in particular in relation to the integration of the intercultural dimension into language teaching and learning.

Au cours des récentes décennies l'enseignement–apprentissage des langues s'est vu redéfini et a connu une rapide évolution en matière de méthodologie. On peut aujourd'hui délivrer les cursus de langue par le moyen d'environnements technologiques, et il est devenu banal de communiquer internationalement de cette façon. Dans la présente étude nous cherchons d'une part à cerner les défis que présente cette évolution pour les rôles et responsabilités traditionnels des enseignants de langue. D'autre part nous demandons dans quelle mesure les modèles en vigueur en matière de formation des enseignants reconnaissent les nouveaux besoins de ceux‐ci, notamment en ce qui concerne l'intégration de la dimension interculturelle dans leur pratique.

Im Bereich Sprachenlehren und lernen haben sich in den letzten Jahrzehnten grundlegende Veränderungen ergeben, vor allem im Hinblick auf Methodologie. Sprachkurse können jetzt per Computer zu den Adressaten gebracht werden und Kommunikation über Grenzen hinweg wird potentiell zum alltäglichen Ereignis. Hier soll untersucht werden inwieweit diese Entwicklungen die traditionelle Rolle und den Verantwortungsbereich von Sprachenlehrer/innen erweitert und verändert haben. Darüberhinaus wird überprüft inwieweit die herkömmliche Ausbildung der Sprachenlehrer/innen den heutigen Anforderungen gerecht wird, vor allem im Hinblick auf die interkulturelle Dimension des Lehren und Lernens von Fremd‐ und Zweitsprachen.

En las últimas décadas la enseñanza y el aprendizaje de las lenguas ha pasado por una redefinición de su contenido y un rápido cambio en su metodología. Los programas de estudios se pueden realizar en entornos basados en las nuevas tecnologías y la comunicación a nivel internacional puede darse a diario. Este artículo de una parte analiza de qué manera estos cambios han ampliado y desafiado los papeles y las responsabilidades que los profesores de lenguas han tenido tradicionalmente. De otra parte, examina hasta qué punto los modelos que se han venido utilizando para la formación de profesores de idiomas reconocen y suplen sus necesidades en la actualidad, en particular en lo que se refiere a la integración de la dimensión intercultural en la enseñanza y el aprendizaje de las lenguas.     

Developing understanding of mathematical modeling in secondary teacher preparation

This study examines the evolution of 11 prospective teachers’ understanding of mathematical modeling through the implementation of a modeling module within a curriculum course in a secondary teacher preparation program. While the prospective teachers had not previously taken a course on mathematical modeling, they will be expected to include modeling as part of the school curriculum under current state standards. The module consisted of readings, analysis of the Common Core State Standards, carefully designed modeling activities, individual and group work, discussion, presentations, and reflections. The results show that while most prospective teachers had misconceived definitions of mathematical modeling prior to the module, they developed the correct understanding of modeling as an iterative process involving making assumptions and validating conclusions connected to everyday situations. The study reveals how the prospective teachers translated the modeling cycle into practice in the context of a carefully designed open-ended problem and the strong connections between modeling activities and promoting mathematical practices.     

Eliciting critical literacy narratives of bi/multilingual teacher candidates across U.S. teacher education contexts

This paper examines critical literacy narratives of bi/multilingual preservice teachers across contexts in the United States. It draws upon empirical data from two studies—a narrative inquiry with Latino teacher candidates in the Midwest and a participatory action research project with bilingual preservice teachers in Hawaii—to examine participants’ identities and experience in academia. Preservice teachers in both studies resisted the labeling practice of “minority” and challenged simplistic notions of “bilingual teacher identity.” This cross-examination argues for further ways to explore how teacher preparation programs should create dialogic spaces for making the voices of diverse preservice teachers heard.

Prospective teacher learning: recognizing evidence of conceptual understanding

This study examined prospective teachers’ (PSTs) ability to recognize evidence of children’s conceptual understanding of mathematics in three content areas before and after an instructional intervention designed to support this ability. It also investigates the role PSTs’ content knowledge plays in their ability to recognize children’s mathematical understanding. Results of content knowledge assessments administered at the beginning of the study revealed that content knowledge did seem to support PSTs’ analyses of children’s understanding when the child’s response demonstrated understanding or demonstrated a misconception. Content knowledge did not seem to support PSTs’ analyses of children’s procedural responses, as many PSTs with good content knowledge initially characterized procedural solutions as evidence of conceptual understanding. Similarly, content knowledge did not seem to support PSTs’ analyses of children’s responses with features commonly associated with understanding but not evidence of understanding. After the instructional intervention consisting of three multifaceted lessons in which PSTs examined many examples of student thinking, they showed improved ability to analyze responses with conceptual features and no evidence of conceptual understanding and responses demonstrating procedural knowledge. Results suggest that content knowledge is not sufficient for supporting PSTs’ analysis of children’s thinking, and that building activities such as the intervention into content courses may help develop this ability. Implications for teacher education programs and future research are considered.     

Language experience narratives and the role of autobiographical reasoning in becoming an urban science teacher

One of the central challenges globalization and immigration present to education is how to construct school language policies, procedures, and curricula to support academic success of immigrant youth. This case-study compares and contrasts language experience narratives along Elena’s developmental trajectory of becoming an urban science teacher. Elena reflects upon her early language experiences and her more recent experiences as a preservice science teacher in elementary dual language classrooms. The findings from Elena’s early schooling experiences provide an analysis of the linkages between Elena’s developing English proficiency, her Spanish proficiency, and her autobiographical reasoning. Elena’s experiences as a preservice teacher in two elementary dual language classrooms indicates ways in which those experiences helped to reframe her views about the intersections between language learning and science learning. I propose the language experience narrative, as a subset of the life story, as a way to understand how preservice teachers reconstruct past language experiences, connect to the present, and anticipate future language practices.     

Student and teacher experiences of assessing different levels of understanding

Examinations greatly influence course structures and student study strategies. A course for students in the civil and environmental engineering programme at Luleå University of Technology was reconstructed with the aim of increasing levels of understanding. A simple written test was designed to assess low levels of understanding (definitions, concepts, etc.). Laboratory work, fieldwork and extensive assignments (calculation tasks) were intended to assess medium levels of understanding (apply, use and combine algorithms, etc.). A final oral group exam that was used to assess high levels of understanding (compare/contrast, explain causes, analyse, relate) concluded the course. Peer assessment of laboratory work and assignments was also applied. The students ranked the entire course at 5 on a 6 grade scale and appreciated the extensive assignments and the assessment approach.     

Almost thinking counterfactually: children's understanding of close counterfactuals

Saying something almost happened indicates that one is considering a close counterfactual world. Previous evidence suggested that children start to consider these close counterfactuals at around 2 years of age (P. L. Harris, 1997), substantially earlier than they pass other tests of counterfactual thinking. However, this success appears to result from false positives. In Experiment 1 (N = 41), 3- and 4-year-olds could identify a character who almost completed an action when the comparison did not complete it. However, in Experiments 1 and 2 (N = 98), children performed poorly when the comparison character completed the action. In Experiment 3 (N = 28), 5- and 6-year-olds consistently passed the task, indicating that they made appropriate counterfactual interpretations of the almost statements. This understanding of close counterfactuals proved more difficult than standard counterfactuals.     

Toward an understanding of higher-order thinking among minority students

Recent investigations have established the importance of higher-order thinking in the acquisition and application of learning skills in diverse domains of inquiry. Such findings have implications for enhancing the quality of thinking of all children but have particular significance for those minority students who historically have not performed as well as their more economically advantaged peers. Although much has been written about the construct, research is still needed to identify the specific processes underlying higher-order thinking and to examine its use among minority populations. A principal-factors extraction with varimax rotation analysis was used in the present study to clarify the nature and function of higher-order thinking among minority students from economically disadvantaged backgrounds. The results allowed for a specification of the mental processes associated with the construct and the extent to which students reported an awareness and use of these processes in academic problem-solving situations.     

Videotaping: A tool for enhancing the teacher’s understanding of cognitive science and teacher self-development

Follow-up research is required to investigate the effects of our beginning teacher preparation programs for secondary science teachers on classroom performance, student achievement, and higher order mental functioning of classroom teachers. Nevertheless, preliminary indications from working with students during the last several years show many encouraging outcomes among beginning teachers, including: increased knowledge of cognitive science, especially applications in instruction and learning; development of more analytical, self-directed classroom behavior; and enhanced capability of utilizing and powerful tool of video-taping for professional self-improvment.     

Uses of video in understanding and improving mathematical thinking and teaching

This article characterizes my use of video as a tool for research, design and development. I argue that videos, while a potentially overwhelming source of data, provide the kind of large bandwidth that enables one to capture phenomena that one might otherwise miss; and that although the act of taping is in itself an act of selection, there is typically enough shown in a video that it rewards multiple watching and supports the kinds of arguments over data that are essential for theory testing and replication. In pragmatic terms, video presents phenomena in ways that have an immediacy that is tremendously valuable. I discuss ways in which videos help students and teachers focus on phenomena that might otherwise be very hard to grapple with. This article begins with a brief review of my uses of video, almost 40 years ago, for research and development in problem solving. It then moves to the discussion of very fine-grained research on learning and decision making. The bulk of the article is devoted to a discussion of the teaching for robust understanding (TRU) framework, which was derived in large measure from the extensive review of classroom videotapes, and which serves as the basis for an extensive program of pre-service and in-service professional development. The professional development relies heavily on the use of videos to convey the key ideas in TRU, and to help teachers plan and review instruction.     

Differentiation: Processing and understanding in teachers' thinking and practice

Teachers' approaches to differentiation are described as a relationship between their planning, daily practice and thinking. Differences between the practice and thinking of teachers and implications for improving practice in differentiation are considered.

The place of teachers' beliefs in research on teacher thinking and decision making,and an alternative methodology

Recent research on teacher thinking and decision making is reviewed, together with the models that gave rise to this work, to show first that scant and insufficient attention has been given to the content of teachers' thinking, specifically their beliefs and principles, and second that because of this, the inferences made in these studies are flawed by assumptions, especially by the assumption that teachers and researchers share perceptions and so understand language identically.An alternative methodology for acquiring an understanding of teachers' beliefs and principles is described and illustrated with a case study. This methodology is an adaptation of Kelly's Repertory Grid Technique.
