Teachers’ dilemmatic decision-making: reconciling coexisting policies of increased student retention and performance

In recent years, many countries within the Organisation for Economic Co-operation and Development have formulated educational policies aimed at providing better education to more students. However, this may be perceived as constituting dilemmatic spaces, where teachers must make efforts to reconcile coexisting political demands in their everyday work. The purpose of this article is to provide insight into how teachers handle coexisting educational policies of increased student retention and performance. Empirical findings from a one-year field study at a Danish vocational school explore how teachers’ decision-making as response to coexisting demands of increased student retention and performance involves the development of various pedagogical approaches to the students: an active ‘caring’ approach, a passive ‘wait until this class is over’ approach, an active ‘vocational gate-keeping’ approach, and a passive ‘wait and see whether they drop out’ approach. Based on the findings, it is argued that the various pedagogical approaches are developed through social negotiations with leaders, students, and other teachers. Moreover, these pedagogical approaches lead to the development of further negotiated, dilemmatic decisions to be made. Thus, a dynamic approach to teachers’ dilemmatic decision-making is proposed.     

Teach For/Teach First candidates: what conclusions do they draw from their time in teaching?

Teach For and Teach First programs now constitute a significant pathway into teaching in a number of countries. One criterion for selection into these programs is leadership capacity, and evidence indicates that many candidates do move into leadership roles in education, business, and policy in the years following their time as a Teach For/Teach First candidate. Given their capacity to influence policy directions and school practice, and to speak with the authority of at least some experience in challenging schools, it is important to understand the types of conclusions they draw from their time in teaching, and the solutions they propose to the problems of educational inequality. This study set out to explore the types of attributions made by 76 Teach For candidates for the low achievement of disadvantaged students, and what they consider to be potential means of effectively addressing the achievement gap. Participants gave most importance to the types of people attracted to and retained in teaching, and placed relatively little importance on improving school resourcing or addressing systemic and structural contributions to educational disadvantage. Implications for those training and working with Teach For candidates are discussed.     

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.     

The impact of international programs on pedagogical practices of their participants: a Russian experience

International exchange and training programs play a significant role in the development of international cooperation between educators from different nations. More and more teachers and school administrators participate in exchange programs and implement new curricular and instructional practices in their institutions. The objectives of this interpretive exploratory case study were (a) to investigate the impact of international exchange and training programs on pedagogical practices of Russian school teachers and administrators and (b) to find out how participants of international programs apply, implement, and transfer their experiences and knowledge that they obtain during their programs. The data were collected through personal interviews, observations, and materials from several debriefing sessions in 2005. The study demonstrated that the participation in international programs significantly impacts educators’ pedagogical practices, expands the range of their instructional approaches, makes program alumni more culturally sensitive and perceptive, and influences their interpersonal relations in schools, their professional growth, and social status. This research can be of interest to perspective participants of international programs and practitioners who develop and organize international programs for educators.     

MAGIS: mobile augmented-reality games for instructional support

ABSTRACT

We present Mobile Augmented-Reality Games for Instructional Support (MAGIS), a framework for the development of mobile augmented-reality (AR) games for education. The framework supports off-the-shelf, state-of-the-art technologies that enable AR tracking and rendering on consumer-level mobile devices, and integrates these technologies with content-generation tools that simplify the development of educational AR games, especially those that extensively use narrative-based game design and player-location tracking such as location-based historical or museum adventure games. We use Igpaw: Intramuros, a proof-of-concept game developed using MAGIS, to help describe the current state of the framework and to show its efficacy for implementing outdoor location-based educational games, and we briefly outline future development plans to improve MAGIS’ AR support (especially those involving indoor scenarios) as well as to improve the instructional design and authoring phases of AR applications written using this framework.     

Education 3.0: breaking the mold with technology

In order to meet the needs of today's knowledge economy, education needs to move beyond the industrial age approach of treating all learners as if they are the same and adopt a learner-centered model of education suitable for the information age. To support this model, a new and transformative technology is needed that focuses on mastery and customized learning. This article reviews the existing approaches to educational technology before proposing a new, customizable, open, and interoperable technology: a personalized integrated educational system (PIES) that provides full functionality for students, teachers, parents and other stakeholders and bridges the gaps between formal and informal learning. PIES' four primary functions: record keeping, planning, instruction, and assessment, as well as secondary functions, are defined and described. Future challenges and research opportunities are also identified.     

Reading in pairs Network: a training model based on peer learning (pairs of teachers and school networks) for the sustainability of educational innovation / Red Leemos en pareja: un modelo de formación basado en el aprendizaje entre iguales (parejas de profesores y redes de centros) para la sostenibilidad de la innovación educativa

Abstract

This article presents a study on a Primary and Secondary Education teacher training network from Catalonia for the implementation of the Reading in pairs program. The goal is to describe, analyse, and assess the training model’s characteristics in relation to the learning promoted among participants, as well as the possibilities of actually incorporating educational innovation in the schools. The results suggest that this formative ecosystem permits a degree of learning and understanding of the program and its conceptual foundations that is relevant to the ability to implement it creatively and to adapt it to each school so that its sustainability is guaranteed.     

‘Teaching between the lines’: discussing,interpreting and writing stories together / ‘El aula entre líneas’: hablamos,interpretamos y escribimos historias conjuntamente

Abstract

The purpose of our study was to carry out a writing workshop in a collaborative setting in which the teacher and the 14 year-old students made up stories while being observed by a researcher. We used a qualitative methodology similar to the Ethnography of Communication and Discourse Analysis, in which narrative and analytical analyses are seen as complementary, in order to interpret all aspects of the participants’ activities. The analysis of the conversations held in the different working situations defined by the presence or absence of the teacher shows that the guiding role played by the teacher is essential in terms of the students’ acquisition of knowledge concerning the generalization of meanings, the organization of social relations and the structuring of the task. Likewise, within a group of peers involved in working towards a common goal, one or several of them tend to take on the guiding role when the teacher is not present.     

Pedagogy in the multimodal classroom: an analysis of the challenges and opportunities for teachers

Contemporary commentary notes that students are frequently ahead of their teachers in their ability to manipulate and be creative with the internet, digital programs, and mobile technology. In this context it is important to ask, ‘What knowledge do teachers need to teach in the contemporary context where texts are elaborately multimodal, constructed not just of print but of image, sound, and movement?’ This paper proposes some signposts to assist teachers with navigating in this environment. Using teachers’ and researchers’ reflections on practices in a diverse range of settings, both primary and secondary, the analysis explicates the challenges that teachers face in this multimodal context and elucidates some ways they can effectively operate within it. In particular, it argues that it is teachers’ expertise as analysts and critics of texts that needs to guide their planning and teaching in this ‘new’ text world.
