Students’ engagement with two-dimensional (2D) representations as opposed to three-dimensional (3D) representations of anatomy such as in dissection, is significant in terms of the depth of their comprehension. This qualitative study aimed to understand how students learned anatomy using observational and drawing activities that included touch, called haptics. Five volunteer second year medical students at the University of Cape Town participated in a six-day educational intervention in which a novel “haptico-visual observation and drawing” (HVOD) method was employed. Data were collected through individual interviews as well as a focus group discussion. The HVOD method was successfully applied by all the participants, who reported an improvement of their cognitive understanding and memorization of the 3D form of the anatomical part. All the five participants described the development of a “mental picture” of the object as being central to “deep learning.” The use of the haptic senses coupled with the simultaneous act of drawing enrolled sources of information that were reported by the participants to have enabled better memorization. We postulate that the more sources of information about an object, the greater degree of complexity could be appreciated, and therefore the more clearly it could be captured and memorized. The inclusion of haptics has implications for cadaveric dissection versus non-cadaveric forms of learning. This study was limited by its sample size as well as the bias and position of the researchers, but the sample of five produced a sufficient amount of data to generate a conceptual model and hypothesis.  相似文献

Structured document retrieval makes use of document components as the basis of the retrieval process, rather than complete documents. The inherent relationships between these components make it vital to support users’ natural browsing behaviour in order to offer effective and efficient access to structured documents. This paper examines the concept of best entry points, which are document components from which the user can browse to obtain optimal access to relevant document components. It investigates at the types of best entry points in structured document retrieval, and their usage and effectiveness in real information search tasks.  相似文献

In studying on-line communities, researchers must consider the unique environmental factors involved in order to minimize potential harm to human subjects. In particular, the often commented upon disinhibiting effect of computer-mediated communication can encourage people to agree to or even insist on a kind of public exposure by which they may eventually be harmed. On the Internet, where perceptions of interpersonal affect and effects may be obscured by the nature of the medium itself, care must be taken to guard against not only any increased tendency for researchers to objectify subjects, but also the tendency for subjects to underestimate the potential consequences of consent. The criteria for informed consent that may be sufficient in face-toface research environments are not necessarily so in a medium in which subjective experience is easily objectified and information is easily devalued.  相似文献

This paper traces the dramatic proliferation of leadership roles in English primary and secondar schools, due mainly to central government education policy of the past two decades. This has transformed schools from relatively simple to highly complex organizations and has impacted on the working conditions of, and demands on, teachers, together with many aspects of schooling. These changes are illustrated with typical examples of schools' leadership structures and their functioning. Interview data provide teachers' views on, and reactions to, the changes in school leadership. The paper also reviews the ways in which teacher education institutions have responded in terms of providing initial and in‐service education and training to equip the profession for this new and developing challenge. It examines the reception of such programmes by teachers and the reported impact on schools' management and the role of leadership within it.  相似文献

This paper presents results from an experimental study that examined embedded strategy prompts in digital text and their effects on calibration and metacomprehension accuracies. A sample population of 80 college undergraduates read a digital expository text on the basics of photography. The most robust treatment (mixed) read the text, generated a summary for each page of text, and then was prompted with a metacognitive strategy. The metacognitive treatment received metacognitive strategy prompts only, and the cognitive group implemented the cognitive strategy (summarization) only. A control group read the text with no embedded support. Groups were compared on measures of achievement, attitudes, cognitive load, and metacomprehension and calibration accuracy. Results indicated that a combination of embedded cognitive and metacognitive strategies in digital text improved learner achievement on application-level questions, yielded more accurate predictive calibration, and strengthened the relationship between metacomprehension and performance, all of which are common attributes of an academically successful learner.  相似文献

Students with Attention Deficit Hyperactivity Disorders (ADHD) frequently experience significant difficulty mastering basic academic skills. This meta‐analysis focuses on one specific potential area of learning difficulties for these students: namely, writing. To identify the extent and depth of the potential writing challenges faced by students with ADHD, we conducted a meta‐analysis comparing the writing performance of grade 1 to 12 students with ADHD to their normally achieving peers. We located 44 papers, yielding 45 studies with 87 effect sizes. The average weighted effect sizes showed that students with ADHD obtained lower scores than their normally achieving peers for writing quality (–0.78), output (–0.64), number of genre elements (–0.69), vocabulary (–0.76), spelling (–0.80), and handwriting (–0.62). Contrary to expectations, moderator analyses found that neither study quality nor the source from which ADHD students were drawn (i.e., school/community vs. clinic/hospital) accounted for variability above sampling error alone.  相似文献

Learners in the trades are faced with learning a large amount of technical vocabulary along with the content of their field, but they do not tend to encounter this language outside their courses of study. This technical vocabulary is a core element in their developing knowledge of their trade and their learner identity. This article focuses first on identifying technical vocabulary in Fabrication using specialised written and spoken corpora, and through extensive checking with experts in the field as well as reference sources. A technical word list of 1079 types was developed, along with a list of common abbreviations and their meanings and a list of proper nouns. The technical word list covers over 30% of the vocabulary in the written Fabrication corpus and just over 9% of the spoken Fabrication corpus. The second part of the article discusses this vocabulary in light of the concept of vocational thresholds and provides suggestions for incorporating the word list into pedagogy, including an apprenticeship approach in which a focus on literacy/literacy acquisition is embedded into content teaching. Suggestions for future research are also included.  相似文献

As a field, Teacher Education has lived with continued criticism from governmental and research bodies on the quality of professional preparation and the lack of a strong research base. We respond to such criticisms by considering possibilities for further exploration of the research of practice and the practice of research in both initial and continuing teacher education. As both a theoretical and methodological challenge, this is tied recursively with research and practice in teacher education, for teacher educators, about teacher education. We draw on the theoretical resources of practice theories, to argue that teacher education practice must be informed by the study of the practice of teaching as well as research addressing the teaching of practice. In conclusion, we make a methodological case for reframing the roles of teacher and researcher within a “thirdspace” to consider the practice of researching teaching as recursive and always regenerative.  相似文献
