Using combinations of video,audio and print to teach French at a distance: A case study of the formative evaluation cycle     

Beryl Crooks  Marie -Noëlle Lamy 《European Journal of Psychology of Education - EJPE》1995,10(2):131-144

The materials, procedures and findings of an evaluation of initial approaches to the use of audio visual media in a course teaching the French language to distance learners are reported as a case study of a formative evaluation. The study illustrates the design-research-revision stages of the formative evaluation cycle. Innovative features of the course were the pivotal role played by audiovisual (videocassette and audiocassette) media in providing resource material for teaching and learning, the use of short sequences for intensive study and the high degree of integration between the audiovisual media and the print. Key teaching design features of the draft audiovisual and print packages were identified and evaluated in terms of students’ reactions to them. Central issues of teaching design are discussed in relation to revisions made to the course materials in the light of the evaluation.  相似文献   

Learning Is Moving in New Ways: The Ecological Dynamics of Mathematics Education     

Dor Abrahamson  Raúl Sánchez-García 《学习科学杂志》2016,25(2):203-239

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning.  相似文献

Resistance as method: unhappiness,group feeling,and the limits of participation in a digital storytelling workshop     

Chloë Brushwood Rose 《International journal of qualitative studies in education》2019,32(7):857-871

This paper offers a narrative case study of Mirabel, one participant in a digital storytelling workshop for women who were newcomers to Canada, whose experience compelled me to rethink conceptualizations of participation in social justice-oriented, community-based participatory media projects. Drawing on the work of Sara Ahmed, I consider how Mirabel’s resistance to the ‘promise of happiness’ offered by the group was interpreted by others as a failure to participate. Conversely, I suggest that Mirabel’s experience and her digital story are generative for thinking about resistance as a method of participation and a political resource for the group. I argue that conceptualizations of participation should be complicated to include the kinds of agency demonstrated by participants like Mirabel who resist the norms of the digital storytelling workshop and group culture.  相似文献   

Evaluating a monolingual multinational digital library by using usability: An exploratory approach from a developing country     

lvaro Quijano-Solís  Raúl Novelo-Pea 《International Information and Library Review》2005,37(4):329

In this paper the authors present a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital libraries evaluation in the Mexican context. The study is framed in the evaluation of a multinational and monolingual digital library: the Miguel de Cervantes Virtual Library, from the University of Alicante in Spain. The evaluators were Mexican “expert” users (i.e. Spanish-speaking professional university librarians specialized in electronic reference services) who were asked to carry on an evaluation instrument based on usability criteria as taken from some models in developed countries. Some questions that might be answered with future research are outlined in this paper.  相似文献

The Co-Effects of Query Structure and Expansion on Retrieval Performance in Probabilistic Text Retrieval     

Jaana Kekäläinen  Kalervo Järvelin 《Information Retrieval》2000,1(4):329-344

The effects of query structures and query expansion (QE) on retrieval performance were tested with a best match retrieval system (InQuery¹). Query structure means the use of operators to express the relations between search keys. Six different structures were tested, representing strong structures (e.g., queries with facets or concepts identified) and weak structures (no concepts identified, a query is a bag of search keys). QE was based on concepts, which were first selected from a searching thesaurus, and then expanded by semantic relationships given in the thesaurus. The expansion levels were (a) no expansion, (b) a synonym expansion, (c) a narrower concept expansion, (d) an associative concept expansion, and (e) a cumulative expansion of all other expansions. With weak structures and Boolean structured queries, QE was not very effective. The best performance was achieved with a combination of a facet structure, where search keys within a facet were treated as instances of one search key (the SYN operator), and the largest expansion.  相似文献   

Mobile marketing research: The-state-of-the-art     

Kaan Varnali  Ayşegül Toker 《International Journal of Information Management》2010

Rapid proliferation in the business potential of mobile marketing attracts researchers from various fields to contribute to the growing body of knowledge on the phenomena. Although the literature on mobile marketing is accumulating, the stream of research is still in the development stage, hence is highly inconsistent and fragmented. This paper aims to organize and classify the literature on mobile marketing and assess the-state-of-the-art in order to facilitate future research. The review covers 255 peer-reviewed journal articles from 82 journals published between 2000 and 2008. The resulting framework summarizes the progress in mobile marketing research and provides future research directions.  相似文献
