The meanings of differentiated instruction in the narratives of Eritrean teachers
2021
The principles of inclusive education largely accepted by governments of different countries require differentiated classroom instruction to meet the diverse needs of individual students. Despite this, teachers have differing experiences and understandings about implementing differentiated instruction (DI) and heterogeneous classrooms. This narrative study aimed at exploring the meanings of DI in the Eritrean context, where teachers are not explicitly familiar with the concept, although their teaching practices reflect some level of differentiation. The research data consisted of 17 narrative interviews with Eritrean mathematics and science teachers. The results of the narrative analysis sh…
Versatile Direct and Transpose Matrix Multiplication with Chained Operations: An Optimized Architecture Using Circulant Matrices
2016
With growing demands in real-time control, classification or prediction, algorithms become more complex while low power and small size devices are required. Matrix multiplication (direct or transpose) is common for such computation algorithms. In numerous algorithms, it is also required to perform matrix multiplication repeatedly, where the result of a multiplication is further multiplied again. This work describes a versatile computation procedure and architecture: one of the matrices is stored in internal memory in its circulant form, then, a sequence of direct or transpose multiplications can be performed without timing penalty. The architecture proposes a RAM-ALU block for each matrix c…
Synthesizing on a reconfigurable chip an autonomous robot image processing system
2003
This paper deals with the implementation, in a high density reconfigurable device, of an entire log-polar image processing system. The log-polar vision reduces the amount of data to be stored and processed, simplifying several vision algorithms and making it possible the implementation of a complete processing system on a single chip. This image processing system is specially appropriated for autonomous robotic navigation, since these platforms have typically power consumption, size and weight restrictions. Furthermore, the image processing algorithms involved are time consuming and many times they have also real-time restrictions. A reconfigurable approach on a single chip combines hardwar…
Student–teacher dialectic in the co-creation of a zone of proximal development: an example from kindergarten mathematics
2020
This paper reports on a case study which explores the co-creation of a zone of proximal development (ZPD) in a mathematics teaching-learning activity in a Norwegian kindergarten. To capture the com...
Teacher orchestration of classroom interaction in science: exploring dialogic and authoritative passages in whole-class discussions
2019
Whereas science is fundamentally a result of a dialogic debate, the authoritative approach has been conceived of as a fundamental part of school science. Dialogic interactions encompass the mutual appreciation of different ideas manifested in teacher supportiveness toward students and, in authoritative interactions, the focus is more on the science’s or teacher’s point of view. Whereas dialogic and authoritative interactions have been viewed as oppositional in recent educational research, authoritative interactions could well be the seed for and give strength and meaning to dialogic interactions, and thus, to the overall dialogue. The focus in this study is on the interplay between authorit…
New TEL Environments for Vocational Education – Teacher’s Instructional Perspective
2015
Modern vocational education is increasingly taking place in new technology-enhanced learning (TEL) settings. On the one hand, vocational education can benefit from the opportunities of technological development. On the other hand, such technologies may create new challenges for teachers. Therefore, there is a particular need to pay more attention to the dialogic pedagogical approaches in which teaching should be seen as a dialogical practice involving teacher-student interactions that create contextual opportunities for teachers to trigger students’ learning in new TEL settings. This article reports on an exploratory study about the different ways in which teachers’ instructional activities…
Ziel- und leistungsdifferenziertes Lernen und Arbeiten
2020
An increasing variety of language (learning) biographies characterize a differentiation of goals and achievements in foreign language teaching. At the same time, they have to comply with curricula and assessment standards. The paper points out and reflects possible steps and teaching methods that could be used.
Undergraduate experiment with fractal diffraction gratings
2011
We present a simple diffraction experiment with fractal gratings based on the triadic Cantor set. Diffraction by fractals is proposed as a motivating strategy for students of optics in the potential applications of optical processing. Fraunhofer diffraction patterns are obtained using standard equipment present in most undergraduate physics laboratories and compared with those obtained with conventional periodic gratings. It is shown that fractal gratings produce self-similar diffraction patterns which can be evaluated analytically. Good agreement is obtained between experimental and numerical results. © 2011 IOP Publishing Ltd.
Transnational turn and national models of higher education - The case of Finland
2014
The purpose of the article is to problematize the relationship between the Nordic democratic public higher education tradition and transnational market driven knowledge economy policies. The article illustrates this development with two cases -- quality assurance and internationalisation policies -- where external demands, based mostly on market ideologies, have been introduced with apparently transnational incentives but having national implementations. These transnational pressures are related to a kind of soft governance of higher education policy, characterized by networked decision making and use of expert consultants, which possibly promotes flexible decision-making and efficiency, bu…
Análisis del repertorio musical en los manuales escolares
2021
Una de las concreciones de la pedagogía crítica en la educación musical es la utilización de un repertorio que incorpore las preferencias del alumnado. En este estudio se aborda la presencia de dicho repertorio en los manuales escolares más utilizados en la actualidad. Para ello, se ha accedido a 15 libros de texto, analizando 985 piezas distintas. Las variables empleadas han sido el período histórico o género musical, el estilo dentro del repertorio de la música popular urbana, la antigüedad del autor y la tipología de propuesta didáctica asociada. Los resultados indican que la música popular urbana tiene una escasa presencia en los manuales (8.20%) y no coincide con las preferencias de lo…
