E‐books are a potential assistive technology, offering significant advantages over print books, and accessible materials are now a financial and legal necessity within UK academia. It is often difficult to find supplier information on accessibility, for example, whether files have been tagged for reading order or whether the interface has been tested with assistive technologies. Equally, library staff may lack confidence in identifying accessibility features, making it hard to promote them to students or demand them from suppliers. This article reports on a crowdsourced e‐book audit of 44 e‐book platforms that was undertaken by 33 UK universities during 2016. The research scored different platforms for a range of accessibility issues, and the resulting open data set is presented in a manner that can be interrogated by libraries looking for specific features. A key finding was that the platform can dramatically affect the accessibility of a publisher's content, making it important for publishers to work with suitable vendors to disseminate their publications.  相似文献

Our main goal in this study was to determine whether the use of computer animation and illustration activities in high school can contribute to student achievement in molecular genetics. Three comparable groups of eleventh‐ and twelfth‐grade students participated: the control group (116 students) was taught in the traditional lecture format, whereas the experimental groups received instructions that integrated a computer animation (61 students) or illustration (71 students) activities. We used three research instruments: a multiple‐choice questionnaire; an open‐ended, written questionnaire; and personal interviews. Five of the multiple‐choice questions were also given to students before they received their genetics instruction (pretest). We found that students who participate in the experimental groups improved their knowledge in molecular genetics compared with the control group. However, the open‐ended questions revealed that the computer animation activity was significantly more effective than the illustration activity. On the basis of these findings, we conclude that it is advisable to use computer animations in molecular genetics, especially when teaching about dynamic processes; however, engaging students in illustration activities can still improve their achievement in comparison to traditional instruction. © 2007 Wiley Periodicals, Inc.

This study addresses concerns about boys’ underperformance on literacy tasks compared to girls, by investigating male and females students’ responses to narrative texts. Participants were 142 Grade 9 and 10 students. Achievement orientations, including goals, self‐efficacy, and self‐handicapping, were measured and approach and avoidance factors identified. Boys scored higher than girls on the avoidance factor. The task presented to participants involved reading sections from two narrative texts representing typically male or typically female reading interests. Interest ratings for the narrative text topics and interest levels while reading the texts were monitored, and students’ answers to multiple‐choice questions on text content recorded. Regression analyses confirmed that the influence of gender, achievement orientation, and on‐task text interest on reading performance varied with different patterns of task interest. The findings suggest that students’ achievement orientations and task interests are both important for understanding gender differences in students’ response to narrative texts.  相似文献

A survey of primary schools in England found that girls outperform boys in English across all phases (Ofsted in Moving English forward. Ofsted, Manchester, 2012). The gender gap remains an on-going issue in England, especially for reading attainment. This paper presents evidence of gender differences in learning to read that emerged during the development of a reading scheme for 4- and 5-year-old children in which 372 children from Reception classes in sixteen schools participated in 12-month trials. There were three arms per trial: Intervention non-PD (non-phonically decodable text with mixed methods teaching); Intervention PD (phonically decodable text with mixed methods teaching); and a ‘business as usual’ control condition SP (synthetic phonics and decodable text). Assignment to Intervention condition was randomised. Standardised measures of word reading and comprehension were used. The research provides statistically significant evidence suggesting that boys learn more easily using a mix of whole-word and synthetic phonics approaches. In addition, the evidence indicates that boys learn to read more easily using the natural-style language of ‘real’ books including vocabulary which goes beyond their assumed decoding ability. At post-test, boys using the nonphonically decodable text with mixed methods (Intervention A) were 8 months ahead in reading comprehension compared to boys using a wholly synthetic phonics approach.  相似文献

Autoethnography and narrative inquiry, with their focus on researching the personal dimensions of human experience, are overlapping realms within the field of qualitative research. While the dominant ways of knowing and researching in the academy remain that of empirical observation and critical analysis from a distanced perspective, these approaches attribute little meaning to the culturally relevant and reflexive accounts of those involved in the autoethnographic and narrative inquiry. In this paper, I critically reflect on my experiences of negotiating identities as an academic and educational researcher over time against a backdrop of professional anxieties produced by policy and political imperatives that have increasingly pervaded modern higher education in the UK. Adopting an autoethnographic style, I contemplate the complexities and opportunities that have inscribed my various identities as an educational researcher over a career, crossing from traditional research to creative narrative and arts-informed approaches.  相似文献

Three different techniques were employed to analyze the associative structures mediating performance on an instrumental biconditional discrimination. In all three experiments, rats were trained concurrently on two tasks in which different stimuli signaled which one of two responses would be followed by reward. In each task, one response was rewarded in one stimulus and the other response was rewarded in the other stimulus. Correct responses earned pellets in one task and sucrose in the other task. The transfer procedure was used in Experiment 1A to identify whether or not an association developed between a biconditional discriminative stimulus and its instrumental outcome. Evidence was obtained that a biconditional cue elevated preferentially a new response trained with the same outcome. Experiments 1B and 3 examined the potential contribution of this stimulus-outcome association to biconditional performance by training the biconditional cues as signals (S-s) for the nonreinforcement of a different response. There was no evidence that this operation interfered with the ability of a biconditional cue to control performance of its correct response. In Experiments 1B and 2, the value of the instrumental outcome was reduced in an attempt to assess the contribution of stimulus-response associations to performance on the biconditional discrimination. The results of Experiments 1B and 2 reveal that correct responses were depressed following devaluation of the outcome used to train them, suggesting that learning about the response-outcome relation occurs. The implications of these results for binary and hierarchical models of instrumental learning are discussed.  相似文献

ABSTRACT: This analysis documents the outcomes and impacts from a series of food protection and defense educational programs conducted over a 3‐y period for private and public sector food system professionals. Several measures were used to determine the professions of participants; their improvements in skills and abilities that resulted from workshops; the audiences' most valued program content; practice changes resulting from educational program participation; abilities to recognize and change food system vulnerabilities; and changes in knowledge levels. Findings indicate that the knowledge level and interest within the target audience progressed over the 3‐y period from basic awareness level through more complex and higher order skills and competencies such as being able to walk through a food production, processing, distribution, or retail facility and identify specific vulnerabilities and make specific risk control recommendations. Pre‐ and posttest scores from the 3rd y of educational activities indicate that baseline awareness levels of core content on food protection and defense is now high among those most likely to attend these types of events, and that participants need to be challenged with additional higher‐level education to promote specific skills. This program series proved successful in building important relationships among food industry and regulatory partners. Analysis of the food security investigation (FSI) series will be useful in the development and delivery of new education and outreach efforts. It is hoped that the analysis and discussion will provide the motivation to further develop a set of competencies that can be used to ground educational efforts that focus on securing and defending our food system.  相似文献

Using a Computer Animation to Teach High School Molecular Biology   总被引:1,自引:1,他引:0  
We present an active way to use a computer animation in secondary molecular genetics class. For this purpose we developed an activity booklet that helps students to work interactively with a computer animation which deals with abstract concepts and processes in molecular biology. The achievements of the experimental group were compared with those of a control group by means of a written questionnaire, which the students received right after the molecular genetics instruction. Analysis of the post-test showed that the mean score of the experimental group was significantly higher than the mean score of the control group. This positive trend was also reflected in personal interviews.  相似文献

Mentored undergraduate research has been identified as a high-impact practice that enhances teaching and learning in higher education. It is reported to influence students’ academic, affective, and behavioral outcomes. However, there is only an emerging literature related to student outcomes associated with identity development, specifically students’ personal and professional identities. This integrative literature review examines the intersections and interrelationship across mentoring, undergraduate research, and student identity development. Its results uncover the complexity of the constructs, and their dynamic interrelationship, especially when viewed through the lenses of the sociocultural perspective grounded in the notion of mediated action. Two assumptions undergird this perspective: first, that all investigation takes place at the intersection of these constructs with mediated action, not individuals in isolation, as a unit of analysis; and, second, that any study of identity must focus on an understanding of identity as multiple, dynamic, and situated in personal and cultural contexts (institutional, disciplinary, and external community culture and values). Thus, the sociocultural perspective and its underlying assumptions shape the proposed research agenda. This research agenda has the potential to advance current knowledge related to mentored undergraduate research and the confluence of elements that contribute to student personal and cultural identities (academic, disciplinary, and professional). Findings from this work will inform our understanding of learning and knowledge construction in sociocultural context, and the trajectory of identity development of students engaged in high-impact learning experiences.  相似文献

Problem-solving by everyday individuals is thought to occur as a two-step process. First, an individual identifies or formulates a problem, followed by entering into a subsequent search to find the best solution. Here, however, we consider an alternative process that everyday individuals may use for solution finding first theorized by von Hippel and von Krogh (2016). Specifically, von Hippel and von Krogh proposed that everyday individuals may sometimes discover a solution and the need it satisfies simultaneously without the need for apriori problem formation, a cognitive process they called “need-solution pair recognition”. Utilizing a rich literature from psychology and neuroscience, we propose that seemingly spontaneous discoveries found by need-solution pair recognition are natural products of the object recognition system and its underlying mechanisms. This view asserts that on encountering an object and reasoning how it might be used (i.e. functional object understanding), an individual's perception of an object may culminate in recognizing the object as a solution, and in some cases, as a solution to a problem previously unknown to him or her, thus bypassing formal problem-formulation and active solution searching entirely. To empirically test this view, we manipulated the ability of everyday individuals to functionally reason about objects while we examined the spontaneous occurrence of solutions found by either need-solution pair recognition or traditional problem-first problem-solving. Consistent with our hypothesized mechanism, our results indicate that need-solution pair recognition occurs more frequently when constraints on functional object understanding are reduced. That is, we found that needsolution pair discoveries outpaced solutions found from traditional problem solving, in environments with unfamiliar objects, where participants were not directed to solve specific problems. Our results provide clear evidence that everyday individuals in the household sector do not always innovate through traditional problem-solving processes, but instead may arrive at solutions as they recognize and reason about objects. Implications for research and practice in household innovation, and for innovation more generally are considered.  相似文献
