Nine television news stories were presented to 60 college students under three different visual format treatment conditions: newscaster‐only presentation, newscaster‐plus‐film or newscaster‐plus‐stills. Detailed information gain from the news stories was tested using a 27‐item multiple‐choice questionnaire which was administered immediately after viewing. It was found that overall learning was slightly, though not significantly, poorer from stories accompanied by picture materials than from those presented by the newscaster alone. It is suggested that news editors assumptions about the effects of pictorial material upon news impact may be only partially correct. 相似文献

A sample of 68 university undergraduates were presented with a sequence of violent and nonviolent news stories either audiovisually (via television), in audio only or in print. Subjects were tested for cued recall of story content immediately after presentation. There was a significant main effect of presentation mode: recall of news was best from print and worst in the audiovisual condition. Significant interaction occurred between sex, mode and news type: males recalled violent news better than non‐violent news, while for females the reverse was true. Males also recalled violent news much better than females in the audiovisual mode, but no such difference occurred in any other mode. Results indicate that reading the news can produce better retention than listening to or watching it. Furthermore, the presentation of violent news stories audiovisually (on videotape) can produce especially impaired memory performance among female viewers. 相似文献

Research into picture effects on encoding of verbal material has paid little attention to the effects of picture changes. In this experiment, it was found that adults’ recall of the spoken text in a TV news item was impaired by mid‐sentence picture editing. In contrast, both 11‐12 year old and 14‐15 year old children's recall was enhanced by rapid cutting, so long as the accompanying pictures were relevant to the verbal text. Both adults’ and younger children's recall was better with some of the experimentally‐manipulated material than it was with the original broadcast version of the news item. However, 14‐15 year olds performed best with the original version.
It is suggested that viewers are differentially sensitive to unintended production effects and that their processing of verbal information can be disrupted by inappropriately‐timed picture cuts. Research on picture‐text relationships in audio‐visual material needs to take account of picture‐timing, as well as picture content, and television editing procedures may need to be tailored more specifically to suit the intended audience. 相似文献

Kagan's Matching Familiar Figures Test was used to select 36 impulsive and 36 reflective children at each of three grade levels: kindergarten, second, and fifth. An incidental learning paradigm was used to assess the child's recall of central and incidental information. Reflective subjects recalled more central and incidental information than impulsives, suggesting that impulsives have difficulty encoding information for storage. Central recall increased with grade level but incidental learning remained constant, a finding consistent with the developmental trend found in previous investigations. A task order effect was found in the recall of central information with more errors made when the central recall task was presented after the incidental. This order effect may account for the higher central recall scores found in previous investigations. Other problems with the incidental learning paradigms raise questions about the validity of the task for inferring selective attention. Despite the problems associated with the task, the results offer further evidence to support the notion that impulsive and reflective children differ on dimensions other than response latency. 相似文献

The purpose of this investigation was to quantitatively and qualitatively identify the study methods and learning strategies that veterinary students used to study anatomy during their first year of professional school and to correlate these with their academic achievement and long‐term recall of information. It was surmised that active study methods would be more beneficial than passive method, but this hypothesis was not supported. The activity or passivity of each study method was secondary to the way in which the students processed the learning. No single study method was associated with academic success or long‐term recall; instead, successful students used a multitude of study methods while the struggling students relied on a single method alone, although these methods varied from student to student. Students and their study methods were profiled using the qualitative technique known as phenomenographic analysis to find those who studied in a deep or surface way. The deep‐processing students, who commonly used multiple study methods, not only succeeded in the class but also had better recall. Students who relied on a memorization‐heavy surface approach to learning had limited recall and tended to perform poorly in the class. These results strongly suggest that by encouraging students to integrate their studying by using multiple methods educators can improve both student grades and recall of complex topics.

The following study investigated the effectiveness of comprehension preadjunct questions as a learning strategy for older adults in a classroom setting. Preadjunct questions are questions presented at the beginning of the to‐be‐learned material to guide what is learned and to increase the likelihood that learners will correctly answer criterion test questions. Fifty‐five adults from 55 to 70 years of age were randomly assigned to two groups: the preadjunct question group and a no‐question control group. The groups viewed a video on high blood pressure and completed a recall posttest immediately after viewing the video and 7 days later. Results demonstrated that there was no significant difference between groups. However, the no‐question control group obtained a higher mean score on both the immediate and delayed recall tests than did the preadjunct question group. Results were explained in terms of resource theory of cognitive aging. If educators plan to use preadjunct questions when teaching older adults, they are advised to build opportunities for training and practice into their teaching plans. 相似文献

The construction of asynchronous learning environments often involves the creation of self‐paced multimedia instructional episodes that provide the learner with control over the pacing of instruction (segmentation); however, does the amount of segmentation impact learning? This study explored the effects of the degree of segmentation on recall and application of new knowledge and the nature of learner dispositions toward segmentation. Undergraduate students (n = 212) were randomly assigned to engage in a 9‐minute multimedia tutorial (ie, instructionally designed video‐based presentation) addressing historical inquiry that was divided into 1, 7, 14 or 28 segments (degree of segmentation) where students had control over when each segment began via a “Continue” button. Students' dispositions toward the segmentation—helped learning, made learning easier, made learning confusing, was annoying or seemed appropriate—were also measured. Results indicated that increased segmentation facilitated recall and application; however, learners perceived a high degree of segmentation (28 segments) more negatively. Overall, these results indicate that increased segmentation within a multimedia instructional environment has a positive influence on recall and application, regardless of the learner's disposition toward the segmentation. 相似文献

The present study considers the design and implementation of immediacy behaviors for an animated agent and the influence of such an agent on viewers. Immediacy, a widely studied construct in human communication research, is defined as the verbal and nonverbal communication behaviors that enhance physical and psychological closeness between people. In this study, the use of animated agent immediacy with new technology, a handheld computer, was studied as a form of affective computing. The purpose of the study was first to find out whether users perceive the communication behaviors of the agent that were intended to enhance immediacy, second, what effects animated agent immediacy has on evaluations of a news service, and third whether affective learning or recall of news content is related to agent immediacy. The results revealed that communication behaviors that enhance immediacy were perceived by the users. Those behaviors were also related to their perception of immediacy. However, the animated agent immediacy did not have a significant effect on evaluation of the news service. Additionally, agent immediacy had no effect on affective or cognitive learning from the news. The results show that it is possible to construct immediacy behaviors for the animated agents, but in this context the influences differed from those reported in human‐to‐human communication. The possibilities for and consequences of agent immediacy are also discussed, as are the reasons why the effects of immediacy on evaluations and learning were not found in the present study. 相似文献

This paper reports a study exploring the learning styles and perceptions of a group of undergraduate and postgraduate learners in a university in the UK in relation to using the web for learning. In particular, we explore the sequential/global learning style dimension (which is concerned with the progress of understanding) in relation to three categories of web‐based interaction: learner‐tutor, learner‐learner, and learner‐information. An Index of Learning Styles is used as the tool to explore this dimension. The findings are presented with regard to the learning preferences of a group of learners towards these three categories of interaction. We conclude with a discussion of these findings in relation to Interactive Learning Systems (ILSs) design. 相似文献

Effortful retrieval produces greater long‐term recall of information when compared to studying (i.e., reading), as do learning sessions that are distributed (i.e., spaced apart) when compared to those that are massed together. Although the retrieval and distributed practice effects are well‐established in the cognitive science literature, no studies have examined their additive effect with regard to learning anatomy information. The aim of this study was to determine how the benefits of retrieval practice vary with massed versus distributed learning. Participants used the following strategies to learn sets of skeletal muscle anatomy: (1) studying on three different days over a seven day period (SSSS7,2,0), (2) studying and retrieving on three different days over a seven day period (SRSR7,2,0), (3) studying on two different days over a two day period (SSSSSS2,0), (4) studying and retrieving on two separate days over a two day period (SRSRSR2,0), and (5) studying and retrieving on one day (SRx60). All strategies consisted of 12 learning phases and lasted exactly 24 minutes. Muscle information retention was assessed via free recall and using repeated measures ANOVAs. A week after learning, the recall scores were 24.72 ± 3.12, 33.88 ± 3.48, 15.51 ± 2.48, 20.72 ± 2.94, and 12.86 ± 2.05 for the SSSS7,2,0, SRSR7,2,0, SSSSSS2,0, STSTST2,0, and SRx60 strategies, respectively. In conclusion, the distributed strategies produced significantly better recall than the massed strategies, the retrieval‐based strategies produced significantly better recall than the studying strategies, and the combination of distributed and retrieval practice generated the greatest recall of anatomy information.

This study assesses information processing and memory functioning in 50 children diagnosed with Attention Deficit Hyperactive Disorder (ADHD) with and without learning disabilities (LD). Mode of presentation (visual vs. auditory), type of memory processing (immediate, short-term, and long-term), and order of recall (ordered vs. unordered) were assessed using the Learning Efficiency Test-II (LET-II). Both groups demonstrated difficulty with auditory ordered recall and lost substantial information from immediate memory to short-term and long-term memory stores. The ADHD/LD group also demonstrated more difficulty with ordered recall than the ADHD only group. While there were no differences between the two groups in regard to immediate recall, the ADHD/LD group demonstrated more problems transferring information into short-term and long-term memory stores than the ADHD only group. Verbal interference effects significantly decreased retention for both visual and auditory processing. Results indicate that ADHD alone presents significant problems in information processing, but the comorbid effects of a learning disability further intensify the negative impact of ADHD. © 1996 John Wiley & Sons, Inc. 相似文献

An animated concept map is a presentation of a network diagram in which nodes and links are sequentially added or modified. An experiment compared learning from animated concept maps and text by randomly assigning 133 undergraduates to study 1 of 4 narrated animations presenting semantically equivalent information accompanied by identical audio narration. Two of the animations presented text; one with concurrent audio and another with delayed audio. Two of the animations presented concept maps; one in black and white and the other with nodes colored to represent semantic relatedness. The concept map groups outperformed the text groups on free recall (p < .05). The black-and-white concept map group outperformed the text groups on a multiple-choice knowledge test (p < .05). No advantages were statistically detected for color enhancements of the animated map. The results indicate that verbal information can be effectively communicated by learner-paced animated concept maps accompanied by audio narrations. 相似文献

Anatomy students studying dissected anatomical specimens were subjected to either a loosely‐guided, self‐directed learning environment or a strictly‐guided, preformatted gross anatomy laboratory session. The current study's guiding questions were: (1) do strictly‐guided gross anatomy laboratory sessions lead to higher learning gains than loosely‐guided experiences? and (2) are there differences in the recall of anatomical knowledge between students who undergo the two types of laboratory sessions after weeks and months? The design was a randomized controlled trial. The participants were 360 second‐year medical students attending a gross anatomy laboratory course on the anatomy of the hand. Half of the students, the experimental group, were subjected without prior warning to station‐based laboratory sessions; the other half, the control group, to loosely‐guided laboratory sessions, which was the course's prevailing educational method at the time. The recall of anatomical knowledge was measured by written reproduction of 12 anatomical names at four points in time: immediately after the laboratory experience, then one week, five weeks, and eight months later. The strictly‐guided group scored higher than the loosely‐guided group at all time‐points. Repeated ANOVA showed no interaction between the results of the two types of laboratory sessions (P = 0.121) and a significant between‐subject effect (P ≤ 0.001). Therefore, levels of anatomical knowledge retrieved were significantly higher for the strictly‐guided group than for the loosely‐guided group at all times. It was concluded that gross anatomy laboratory sessions with strict instructions resulted in the recall of a larger amount of anatomical knowledge, even after eight months.

This study investigated whether active learning within computer‐based training courses can be measured and whether it serves as a predictor of learner‐perceived course quality. A major corporation participated in this research, providing access to internal employee training courses, training representatives, and historical course evaluation data. Twenty sample courses were subdivided into 1,884 time‐based instructional events and categorized by eight design principles for learner engagement: attend, organize, recall, practice, interact, apply, explore, and absorb. This analysis produces a quantitative pattern for the cognitive activity a course encourages within the learner, summarized as the active learning index. A regression model, with the active learning index as a predictor variable for learner‐perceived course quality, resulted in a correlation coefficient of .83 (r2=.69) and a p‐value <.0001. These results suggest a framework for quantifying the active learning components in computer‐based training courses and guiding the work of instructional designers toward higher‐quality courses. 相似文献

An experiment in which four qualities of screen image from the same educational television programme were presented to randomised groups of school sixth‐form students is described. Picture quality was found to influence significantly short‐term recall of factual visual information from the programme, a matter having implications for broadcast standards and capital investment in ETV. Subsidiary findings regarding performance differences on visual recall tests according to sex and sixth‐form subjects studied are also reported. 相似文献

Abstract Whether and how the administration of one retention test affects performance in a subsequent test on the same material is a question of practical and theoretical interest to educationalists and psychologists. Previous research suggests a number of conclusions which generalise across both materials and procedures. A systematic investigation is described concerning the recognition and free recall of long lists of unrelated words. Finally, a model of recognition and recall is presented which claims that both tasks employ knowledge about the occurrence of individual items in the acquisition list and knowledge about the organisational structure of that list. It is argued that the administration of a recall test affects only the first kind of information, whereas the administration of a recognition test affects only the second kind of information. 相似文献

Changes in visual attention and story comprehension for children (N = 132) with attention deficit hyperactivity disorder (ADHD) and comparison peers were examined. Between the ages of 7 and 9 (Phase 1) and approximately 21 months later (Phase 2), children viewed 2 televised stories: 1 in the presence of toys and 1 in their absence. Both groups of children showed developmental increases in visual attention and stable group differences over time. Deficits in comprehension among children with ADHD, however, increased over time. Whereas comparison children’s recall of factual and causal information increased over time in both viewing conditions, children with ADHD showed no developmental improvement in recall of factual information in the toys‐present condition and no improvement in recall of causal relations in either viewing condition. 相似文献

The skeletons in our closet: E‐learning tools and what happens when one side does not fit all 
下载免费PDF全文
下载免费PDF全文 In the anatomical sciences, e‐learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual‐kinesthetic learning modalities are scarce. The study examined how a visual‐kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two‐dimensional (2D) e‐learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual‐task study to: (1) investigate if a dual‐task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them. Students were assessed using knowledge scores, Stroop task reaction times, and mental rotation test scores. Results demonstrated that the dual‐task paradigm was not an effective tool for measuring cognitive load across different learning modalities with respect to kinesthetic learning. However, our study highlighted that handing physical specimens yielded major, positive impacts on performance that a simple commercial e‐learning tool failed to deliver (P < 0.001). Furthermore, students with low spatial ability were significantly disadvantaged when they studied the bony joint and were tested on contralateral images (P = 0.046, R = 0.326). This suggests that, despite limbs being mirror images, students should be taught the anatomy of, as well as procedures on, both sides of the human body, enhancing the ability of all students, regardless of spatial ability, to take anatomical knowledge into the clinic and perform successfully.
