Research results of two personal learning environments experiments in a higher education institution
Victoria Marín Juarros Jesús Salinas Ibáñez Bárbara de Benito Crosetti 《Interactive Learning Environments》2014,22(2):205-220
This paper focuses on institutionally powered personal learning environments (iPLEs). The concept of the iPLE can be seen as a way universities can incorporate learner-centred approach into the architecture of their technology-enhanced learning environments. The aim of this paper is to pose that there are other ways to learn complementary to virtual learning environments, such as using distributed Web 2.0 tools from personal learning environments (PLEs). With that aim in mind, this paper presents an exploratory study with two different iPLE configurations, analyses how they modify the learning–teaching process, and reports their perceived usefulness from the students' point of view. These two case studies were carried out by a research group of educational technology from a Spanish university in graduate and postgraduate courses. As reported by other case studies, the results revealed that students use the environment basically in the academic context and this usage is conceived as another time and effort requiring task. This fact can be observed in the low level iPLEs customization. The overall conclusions we can extract are, on the one hand, that the new environment to integrate informal and formal learning should be flexible and adaptable to the student's needs and preferences and, on the other hand, that academic tools might someday become personal tools. 相似文献

This paper sets out to develop key messages for the theory and practice of environmental education from a review of recent research literature on climate change communication (CCC) and education. It focuses on how learners of climate science understand messages on climate change, the communicative contexts for education on climate change, the barriers that can be found to public engagement with climate change issues, and how these barriers can be addressed. 92 peer-reviewed studies were examined. The analysis focuses on the goals and strategies of CCC, and how barriers can be addressed given the research findings on: (a) the content of CCC, (b) visualizations, (c) framing, (d) audience segmentation. The paper concludes that CCC and education need to address barriers to public engagement on several levels simultaneously. It recommends that scholars of environmental education focus critical attention on how practice addresses senses and spheres of agency; sociocultural factors; and the complexities of developing scientific literacy given the interpretative frames and prior understandings that are brought to bear by the public in non-formal education settings. 相似文献

Automated essay scoring programs are becoming more common and more technically advanced. They provoke strong reactions from both their advocates and their detractors. Arguments tend to fall into two categories: technical and principled. This paper argues that since technical difficulties will be overcome with time, the debate ought to be held in terms of the principles. A thought experiment, based on a technically perfect Automated Essay Scorer, is proposed in order to explore the moral questions related to this topic, such as whether students deserve to have their work read by a human. It concludes that affect is an important component both of writing and of the debate, but that if the move to automated scoring stops being an ‘all or nothing’ debate, then many of the objections on principle will be obviated. 相似文献

Spatial visualization ability and laparoscopic skills in novice learners: Evaluating stereoscopic versus monoscopic visualizations 下载免费PDF全文
Victoria A. Roach Manisha R. Mistry Timothy D. Wilson 《Anatomical sciences education》2014,7(4):295-301
Elevated spatial visualization ability (Vz) is thought to influence surgical skill acquisition and performance. Current research suggests that stereo visualization technology and its association with skill performance may confer perceptual advantages. This is of particular interest in laparoscopic skill training, where stereo visualization may confer learning advantages to novices of variant Vz. This study explored laparoscopic skill performance scores in novices with variable spatial ability utilizing stereoscopic and traditional monoscopic visualization paradigms. Utilizing the McGill Inanimate System for Teaching and Evaluating Laparoscopic Skills (MISTELS) scoring protocol it was hypothesized that individuals with high spatial visualization ability (HVz) would achieve higher overall and individual MISTELS task scores as compared to low spatial visualization ability (LVz) counterparts. Further, we also hypothesized that a difference would exist between HVz and LVz individual scores based on the viewing modality employed. No significant difference was observed between HVz and LVz individuals for MISTELS tasks scores, overall or individually under both viewing modalities, despite higher average MISTELS scores for HVz individuals. The lack of difference between scores obtained under the stereo modality suggested that the additional depth that is conferred by the stereoscopic visualization may act to enhance performance for individuals with LVz, potentially equilibrating their performance with their HVz peers. Further experimentation is required to better ascertain the effects of stereo visualization in individuals of high and low Vz, though it appears stereoscopic visualizations could serve as a prosthetic to enhance skill performance.

The benefits of peer collaboration on strategy use, metacognitive causal attribution, and recall were supported in an earlier study (Manion & Alexander, 1997). Following that study two primary questions remained: Would the observed benefits last beyond an immediate posttest, and would they last regardless of which strategy the children chose to use? The current investigation explores those questions. Thirty-one fourth-grade students from two public schools in Sydney, Australia, experienced either a peer-collaborative treatment condition or an individual task (control condition). A posttest was conducted 5.5 weeks later. As was the case in the original study, children in the treatment condition outperformed children in the control condition in strategy use, metacognitive understanding of strategy chosen, and recall gain. Benefits also sustained regardless of the strategy children chose to implement on the task. Most importantly, the benefits lasted after a period of over a month. Implications for future research are discussed. 相似文献
