As academic library collections are moved off site to make room for learning commons-type collaboration spaces, exploratory research processes (e.g. stacks browsing activities) are threatened. Given the range of benefits associated with chance information encounters in the physical book stacks, the disappearance of accessible collections is problematic. Fortunately, by focusing on embodied aspects of the physical browsing experience we can leverage emerging technologies to preserve instances of serendipitous information retrieval. Virtual reality, in this case, provides a browsing platform that allows for the type of search activity typically associated with research in the physical books stacks and preserves the benefits thereof.  相似文献

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.  相似文献

Listening and reading comprehension can be assessed by analyzing children’s visual, verbal, and written representations of their understandings. “Talking Drawings” (McConnell, S. (1993). Talking drawings: A strategy for assisting learners. Journal of Reading, 36(4), 260–269 is one strategy that enables children to combine their prior knowledge with the new information derived from an expository text and “translate” those newly-acquired understandings into other symbol systems, including an oral discussion with a partner, a more detailed drawing, and written labels for the drawing. The Talking Drawings strategy begins by inviting children to create pre-learning drawings. These initial drawings are a way of taking inventory of a child’s current content knowledge about a particular topic. After pre-learning drawings are created and shared, children listen to or read an expository text (e.g., information book, passage from a textbook) on the same topic as their drawing. Pairs of students discuss the information and either modify their pre-learning drawings to be more detailed or create completely new drawings that reflect the recently-acquired information. Students are encouraged to label their drawings with words in a diagram or schematic fashion. By evaluating the “before” and “after” artwork, educators can identify advances in students’ reading and listening comprehension of the terminology, facts, and principles on a particular topic.  相似文献

This article proposes a theoretical frame for technical communication peda- gogy based on six layered literacies: basic, rhetorical, social, technological, ethical, and critical. The layered literacies frame advocates diverse instruction in technical communication programs, ranging from the ancient art of rhetoric to the most contemporary of technologies, from basic reading and writing skills to ethical and critical situational analyses. The article also suggests how the frame can be applied to a program of study or individual course in order to establish teaching objectives; develop course and lesson activities; and assess pedagogical materials, students, and programs.  相似文献

Objectives: To explore how the library service expectations and perceptions of users might differ across health‐related libraries as against major research libraries not operating in a medical context; to determine whether users of medical libraries demand better library service quality, because the inability of users to access needed literature promptly may lead to a patient who cannot be properly diagnosed, or a diagnosis that cannot be properly treated. Methodology: We compared LibQUAL+® total and subscale scores across three groups of US, Canadian and British libraries for this purpose. Results: Anticipated differences in expectations for health as other library settings did not emerge. Conclusions: The expectations and perceptions are similar across different types of health science library settings, hospital and academic, and across other general research libraries.  相似文献

The researchers performed a survey study to determine the effectiveness of collegiate programmes in dispelling common misconceptions about traumatic brain injury (TBI) while preparing undergraduate and graduate students for special education (SpEd) careers. Respondents included 136 undergraduate and 147 graduate SpEd students in their final semesters before obtaining degrees. Each completed an 18‐item true/false survey about TBI and the associated recovery process. Results were compared with survey responses from 318 lay public respondents who participated in a previous study. Two major findings emerged: (a) no significant differences existed in misconception endorsement between SpEd students completing Bachelor's versus Master's degrees; and (b) graduating students in SpEd teacher preparation programmes endorsed similar misconceptions as lay public respondents; hence, these programmes do not appear effective in dispelling common TBI misconceptions. Improving academic preparation for special educators regarding TBI is imperative for effectively identifying, assessing and serving student survivors.  相似文献
