Elaborating pedagogical content knowledge: what it means to know students and think about teaching

The purpose of this study was to examine how a teacher understood her students and then thought and made decisions about content, curriculum and pedagogy. Pedagogical content knowledge (PCK) and Deweyan philosophies of experience and education provided the theoretical frameworks. Data were collected through observations (N?=?38) and interviews (N?=?38) over four months and analysed using constant comparison. Findings indicated that this teacher possessed a broad repertoire of knowledge about students that she used to think and make decisions about content, curriculum and pedagogy. The connections between knowing students and thinking about teaching were more sophisticated and interconnected than is typically recognized or articulated in teacher knowledge literature. Three themes are used to explain how this teacher understood her students’ emotional and social lives in and out of her classroom, and ways it influenced her thinking and teaching. The discussion centers on the need for more comprehensive analyses of teachers’ pedagogical content knowledge.     

Online educational videos according to specific didactics: the case of mathematics / Los Vídeos educativos en línea desde las didácticas específicas: el caso de las matemáticas

Abstract

The vast number of online educational videos available at the moment has generated an emerging area of research concerning their level of suitability. This study considers the epistemic quality of educational videos on mathematics, focusing on the specific content of directly proportional distributions. A qualitative study is used, based on the application of theoretical and methodological tools from the onto-semiotic approach to knowledge and mathematics instruction, principally the notion of epistemic suitability and the identification of algebraic levels. The sample consists of the 31 most popular videos in Spanish on YouTube? on directly proportional distributions. Analysis reveals interesting results on these kinds of resources. In general, it is observed that they are weak in epistemic suitability, which does not seem to affect their level of popularity. Moreover, the existence of videos with inaccurate arguments or incorrect procedures, together with the diversity of algebraic levels used, indicates that teachers should be careful when selecting them and only recommend those that better suit their students’ needs.     

Teacher educators working on their own professional development: goals,activities and outcomes of a project for the professional development of teacher educators

This article reports on the professional development of teacher educators within the context of a national project, ‘Professional Quality of Teacher Educators,’ where a professional standard and a standards‐based procedure of (self‐)assessment and professional development have been created and effectively implemented. This project offered a unique opportunity to analyze the goals, activities and outcomes of the process of professional development of teacher educators in a situation in which this development is promoted by the professional group as a whole. In our research, we used 25 completed portfolio's made by teacher educators participating in the standards‐based procedure of (self‐)assessment and professional development. We found that teacher educators, participating in this procedure, prefer the development of their knowledge and skills over the development of their attitudes and beliefs. For their professional development, the teacher educators experiment with new activities within the work‐situation and interact with colleagues within their professional community, more than that they study theory or reflect on their work. The participating teacher educators experience a positive impact at the personal level (change in cognition and behavior). More than one‐third of them share outcomes with others. Above, they report a more positive self‐esteem and more enthusiasm for teacher education. This article may motivate other countries or institutions to invest in the professional development of teacher educators. Further research is necessary on the essence of the professional qualities of teacher educators and the relation of their professional development with student learning.     

A dynamic analysis of why learners develop a preference for autonomous learners in computer-mediated communication

A large number of studies in CMC have assessed how social interaction, processes and learning outcomes are intertwined. The present research explores how the degree of self-determination of learners, that is the motivational orientation of a learner, influences the communication and interaction patterns in an online Problem Based Learning environment. Given the complexity of CMC, we expected that autonomous learners would be more willing to contribute to cognitive discourse. In time, we expected that control-oriented learners would develop a preferential attachment to contribute to discourse from autonomous learners. Data were gathered from 37 autonomous and 39 control-oriented learners who posted 1669 messages. Using a dynamic multi-method approach of content analysis of cognitive and social discourse, social network analysis, and measures of academic motivation, we find some preliminary evidence that motivational orientation influences communication and social interaction patterns amongst learners. From the beginning, most control-oriented learners develop a preference to connect to and communicate with autonomous learners, although a separate team-analysis indicates that group dynamics also influence how learners develop connections with other learners in time. Our findings further the understanding of differences found in distance learning courses about participation and drop-out.     

Towards flexible learning for adult learners in professional contexts: an activity-focused course design

This article argues for a flexible model of learning for adults which allows them to make choices and contextualise their learning in a manner appropriate to their own professional practice whilst also developing as a member of a learning community. It presents a design based around online ‘learning activities’ which draws on ideas of constructivism, collaborative learning and reflective practice. The model was developed for adult learning in Higher Education, and has been adapted and extended to a number of different programmes. Implementation of the model for the Teaching Qualification (Further Education) has been the subject of an interpretative evaluation using a multiple methods approach. Learners' experiences of this programme together with issues associated with the application of the model to other programmes are discussed.     

Transcultural Risk Communication and Viral Discourses: Grassroots Movements to Manage Global Risks of H1N1 Flu Pandemic

This article proposes a theoretical framework of transcultural risk communication to examine how global connectivities influence communication about H1N1 flu. A case study was conducted to investigate risk management policies at global, regional, and translocal levels to cope with health threats posed by the emerging H1N1 flu epidemic. We explored how risk management approaches by Chinese Internet users facilitated the employment of a unique risk measure of exit and entry screening for returnees to China.
