The present study examined whether or not different input delivery modes have an effect on listening comprehension of Turkish students learning English at the university level. It investigated the effect of one single mode, which is audio-only, and three dual input delivery modes, which were audio-video, audio-video with target language subtitles and audio with PowerPoint presentation, on listening comprehension. The data have been gathered through: a listening proficiency exam, a topic familiarity questionnaire, listening comprehension tests, think-aloud protocols and a semi-structured focus group interview. Analysis of data demonstrated that the students’ listening comprehension scores were significantly lower in audio-video with subtitles mode. In addition to this, the students stated that they experienced most confusion and anxiety in understanding through audio-video with subtitles. Moreover, the students mentioned that they were most successful in the audio with PowerPoint presentation mode. Results also indicated that the students were influenced by their pre-university listening class experiences, meaning that they were most accustomed to the audio-only mode, and therefore felt most relaxed when they listened only.  相似文献

Spatial skills necessary to design and analyze orthographic drawings are sometimes lacking in students. This study investigated whether computer animated graphics which replicate mental images of rotation and dimensional transformation would be useful in the development of spatial skills. Subjects viewed films of three architectural types of graphic representations. In both color and wire frame form, rotating to top and side views, and changing from three to two dimensions. Results indicated that viewing the animated images did have a significant effect on increasing orthographic but not mental rotation test scores. The order in which subjects viewed the films significantly affected their orthographic scores. Furthermore, viewing wire frame images first had a significantly negative effect on subjects’ first mental rotation score.  相似文献

Summary The present study investigated the relationships of meaningfulness, picture detail, and presentation mode on visual learning. Subjects, 123 broadcasting students at Brooklyn College, viewed slides of animal pictures previously classified by judges into high-and low-meaningful groups. All Ss saw both high-and low-meaningful stimulus items. Half saw the stimulus items as full-color pictures while the other half saw them as line drawings. In addition, one-third saw the stimulus items as pictures presented alone, one-third saw them as pictures with each animal name printed underneath its picture, and one-third saw the pictures (without printed names) accompanied by the spoken animal name as each slide was shown. Following presentation of stimulus slides, Ss were shown a series of full-color test slides containing dummy items randomly intermixed with stimulus items. During two showings of test slides, Ss first indicated those animals recognized from the learning trial and second, wrote down those animal names they knew. Results included significant main effects on recognition accuracy for meaningfulness and presentation mode in addition to significant interactions for meaningfulness-by-mode and mode-by-picture-detail. A significant main effect of presentation mode resulted for correctly named stimulus items. Three significant main effects (meaningfulness, picture detail, and mode) and one significant interaction (mean-ingfulness-by-picture-detail) were obtained on error scores.  相似文献

Mobile social media often feature the ability to “Like” content posted by others. This study examined the effect of Likes on youths' neural and behavioral responses to photographs. High school and college students (N = 61, ages 13–21) viewed theirs and others' Instagram photographs while undergoing functional Magnetic Resonance Imaging (fMRI). Participants more often Liked photographs that appeared to have received many (vs. few) Likes. Popular photographs elicited greater activity in multiple brain regions, including the nucleus accumbens (NAcc), a hub of the brain's reward circuitry. NAcc responsivity increased with age for high school but not college students. When viewing images depicting risk‐taking (vs. nonrisky photographs), high school students, but not college students, showed decreased activation of neural regions implicated in cognitive control.  相似文献

This study hypothesized that increased intensity of graphic information, presented in computer-generated instruction, could be differentially beneficial for students with hyperactivity and inattention by improving their ability to sustain attention and hold information in-mind. To this purpose, 18 2nd–4th grade students, recruited from general education classes, were presented with sequenced geometry instruction, which involved projections of solid geometric images accompanied by text and color. Children were randomly assigned to two levels of intensity: high visual intensity (HVI) with information from the light source (e.g., contrasts, shadows) and low intensity (LVI) projecting only a single value. In support of theoretical predictions, students with hyperactivity/inattention performed better than typical comparisons during the performance of advanced problems in the HVI condition. Furthermore, the students with inattention demonstrated significantly better performance in the HVI than in the LVI condition. Educational, research, and development implications of these findings were discussed.  相似文献

Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science.  相似文献

ABSTRACT

Readers often comprehend belief-consistent information from multiple texts better compared with belief-inconsistent information (text-belief consistency effect). The aim of the present study was to investigate whether adolescents’ comprehension of multiple texts is similarly impacted by their beliefs. Moreover, readers’ prior knowledge and an alternating (compared with a blocked) mode of presenting multiple texts were expected to attenuate the text-belief consistency effect. High school students read two belief-consistent and two belief-inconsistent texts on one of two scientific issues in different modes of presentation (blocked vs. alternating). A recognition task was used to assess situation model strength for each text, and prior beliefs and prior knowledge were measured before the main experiment. As expected, in the blocked mode of presentation high school students had a stronger situation model for belief-consistent texts. In the alternating mode of presentation, participants had similar situation model strengths for the different texts. Moreover, high-knowledge participants experienced a text-belief consistency effect, whereas low-knowledge participants had weaker and similar situation models for the texts.  相似文献

This article describes a pedagogical approach to collage based on the work of art historians John Berger (1926–2017) and Aby Warburg (1866–1929). Its aim is to understand how images can be used to develop critical visual thinking skills within the context of architectural education and architectural theory in particular. Drawing on the notions of ‘visual literacy’ and ‘visual learning’ familiar from educational theory, the article proposes collage as a means to challenge the predominantly verbal modes of assessment prevalent in contextual and critical studies, where ‘contextual’ refers to the wider contexts (cultural, social, historical, theoretical) within which architecture is situated. The Collage Workshop, which the author has developed over the last five years whilst working closely with students at both undergraduate and postgraduate level, is a concrete attempt to implement visually oriented forms of learning and reduce the reliance on written assignments across the curriculum. By analysing some examples of collages produced by students who participated in the workshop, the article hopes to show how images can be used in the construction of an argument and, perhaps more crucially, how seeing assumes meaning in an image‐saturated world.  相似文献

In the Visible Korean project, serially sectioned images of the pelvis were made from a female cadaver. Outlines of significant structures in the sectioned images were drawn and stacked to build surface models. To improve the accessibility and informational content of these data, a five‐step process was designed and implemented. First, 154 pelvic structures were outlined with additional surface reconstruction to prepare the image data. Second, the sectioned and outlined images (in a browsing software) as well as the surface models (in a PDF file) were placed on the Visible Korean homepage in a readily‐accessible format. Third, all image data were visualized with interactive elements to stimulate creative learning. Fourth, two‐dimensional (2D) images and three‐dimensional (3D) models were superimposed on one another to provide context and spatial information for students viewing these data. Fifth, images were designed such that structure names would be shown when the mouse pointer hovered over the 2D images or the 3D models. The state‐of‐the‐art sectioned images, outlined images, and surface models, arranged and systematized as described in this study, will aid students in understanding the anatomy of female pelvis. The graphic data accompanied by corresponding magnetic resonance images and computed tomographs are expected to promote the production of 3D simulators for clinical practice.

This study investigated the relationship between the communication source variables of attraction, credibility, and perceived similarity and the overall image of public figures. The arrangement of 15 public figures in a multidimensional space was compared to their arrangement on measures of attraction, credibility, and similarity. The arrangement of public figures in the multidimensional space was based on respondents' paired comparisons among all public figures. Results indicated that most of the theoretic concepts were used by respondents to construct their iamge of public figures. However, the concepts did not emerge as major determinants of that image. It was suggested that these concepts might be part of a latent structure which emerges whenever public figures are viewed as communicative sources.  相似文献

This study investigated five different aspects (mental image, physical image, source of the image, 'scientists around us', and 'my favourite scientist') of Korean students' images of the scientists. The data, quantitative and qualitative, from the responses of a total of 1137 students from three different groups (age 11, 13and 15) were analysed to calculate the relative frequencies of some identified patterns of responses and to make comparisons between different genders and different age groups. Korean students generally showed, but to a slightly lesser extent, some stereotypical images of the scientist which were revealed in previous studies. These were influenced more by affective and ethical personal characteristics of the scientist than by their cognitive and gifted abilities. Some noticeable age-related and gender-related differences were also found and discussed.  相似文献

Anatomical relationships are challenging concepts for first‐year medical students. The use of progressive drawing, where an image is created from a blank template, has long been utilized for outlining anatomical relationships and continuity from one region to another, and has shown positive outcomes for student learning. More recently, computerized progressive drawing has been introduced; however, challenges, including issues with visual clarity, have been described. In this study, 17 computerized screencasts of drawings covering neurovasculature of the limbs, abdomen, pelvis, head, and neck were created and provided to first‐year medical students at Morehouse School of Medicine. An animated method for drawing was utilized to increase visual clarity. Surveys were provided to 181 first‐year medical students to collect feedback about these screencasts. Sixty percent (n = 108) of students completed at least one survey. Respondents rated all 17 screencasts with a minimum of 4.7/5 for helpfulness in learning the material for course examinations. A majority of students (77.8%) reported viewing the screencasts more than once on at least one survey, and students reported varying methods for utilizing the screencasts. A majority of students provided positive feedback relating to technical quality. Some significant differences in course performance were seen based on screencast usage. The positive responses from students indicate that this is a useful method in medical education. Anat Sci Educ 11: 445–460. © 2018 American Association of Anatomists.  相似文献

It is common in the everyday art class to find many examples of avoidance, omission and exaggeration in young adolescents’ depictions of the human figure. When students depict sophisticated human images, they make every effort to avoid the difficult parts, and some students tend to exaggerate the size or distort the shape of the human image. Art educators see these types of behaviour and modes of expression as unnatural, and claim that they may hinder the development of the creativity of young adolescents. Relevant discussions in the literature from a psychological perspective are mainly concerned with the negative impact of such behaviour and modes of expression on the formation of young adolescents’ identities. However, in the context of popular visual culture, the findings of recent studies on young adolescents’ comic drawings have suggested that when young adolescents draw comic characters, they use their everyday life experiences in their drawings. This article reports on a five‐year qualitative longitudinal study conducted in a Hong Kong secondary school. The aim of the study was to deepen our understanding of this behaviour on the part of adolescents in art classes. The findings of the study confirmed the view that these aspects should be interpreted from a cognitive learning perspective. It is suggested that art educators reconsider these types of behaviour and modes of expression as a potential means for improving secondary students’ learning of the art of popular visual culture.  相似文献

Assessment feedback is increasingly being provided in digital modes, from electronic annotations to digital recordings. Digitally recorded feedback is generally considered to be more detailed than text-based feedback. However, few studies have compared digital recordings with other common feedback modes, including non-digital forms such as face-to-face conversations. It is also unclear whether providing multiple feedback modes is better than a single mode. To explore these possibilities, an online survey asked 4514 Australian university students to rate the level of detail, personalisation and usability of the feedback comments they had most recently received. Of the students who received a single feedback mode only, electronic annotations and digital recordings were rated most highly on the three quality indicators. Students who received multiple modes were more likely to agree with all three indicators than those who received a single mode. Finally, students who received multiple modes were more likely to agree that the comments were detailed and usable when one of those modes was a digital recording. These findings enhance our understanding of feedback design, indicating that it is important to consider the strengths and weaknesses of particular modes, and the value of offering multiple modes.  相似文献

This article looks at the way in which the changing visual environment affects education at two levels: in communication patterns and research methodologies. The research considers differences in the variance and quantity of types of visual media and their relationship to the written mode in the urban landscapes of Tokyo and London, using Google Street View to make comparisons. It reflects on the parallels this might have in the ways in which children encounter text in the environment. The data were analysed using Visual Content Analysis and colour coding. It found the Tokyo sample to have a higher density and diversity of visual media types at a wider range of heights. Visual and written communication also appear to be confined to more separately definable spaces with more equal weighting in the use of written and visual modes. Particularly, within the context of early childhood education it is hoped these findings will increase knowledge concerning young children's exposure to the visual mode, initiate wider discourse around this less researched mode's role within new multimodal communication practices and that the methodology furthers understanding of the potential of new media in image‐based research.  相似文献

Anatomical examinations have been designed to assess topographical and/or applied knowledge of anatomy with or without the inclusion of visual resources such as cadaveric specimens or images, radiological images, and/or clinical photographs. Multimedia learning theories have advanced the understanding of how words and images are processed during learning. However, the evidence of the impact of including anatomical and radiological images within written assessments is sparse. This study investigates the impact of including images within clinically oriented single-best-answer questions on students' scores in a tailored online tool. Second-year medical students (n = 174) from six schools in the United Kingdom participated voluntarily in the examination, and 55 students provided free-text comments which were thematically analyzed. All questions were categorized as to whether their stimulus format was purely textual or included an associated image. The type (anatomical and radiological image) and deep structure of images (question referring to a bone or soft tissue on the image) were taken into consideration. Students scored significantly better on questions with images compared to questions without images (P < 0.001), and on questions referring to bones than to soft tissue (P < 0.001), but no difference was found in their performance on anatomical and radiological image questions. The coding highlighted areas of “test applicability” and “challenges faced by the students.” In conclusion, images are critical in medical practice for investigating a patient's anatomy, and this study sets out a way to understand the effects of images on students' performance and their views in commonly employed written assessments.  相似文献

Popular culture images of reading tend to portray readers as solitary individuals deeply immersed in reading a single text in a quiet, undisturbed spot. Yet, in our documentation of adolescent students reading in Singapore secondary schools, we find that there are many ways and modes of reading, much of which is social in nature. Through the use of comparative, critical visual analysis, this paper expands the understanding of what it means to read and to understand how adolescent readers experience reading in school contexts. Visual images serve to disrupt dominant readings of what counts as reading to elicit new considerations for engaging adolescents in reading.  相似文献

The large number of experimentally determined molecular structures has led to the development of a new semiotic system in the life sciences, with increasing use of accurate molecular representations. To determine how this change impacts students’ learning, we incorporated image tests into our introductory cell biology course. Groups of students used a single text dealing with signal transduction, which was supplemented with images made in one of three iconographic styles. Typically, we employed realistic renderings, using computer-generated Protein Data Bank (PDB) structures; realistic-schematic renderings, using shapes inspired by PDB structures; or schematic renderings, using simple geometric shapes to represent cellular components. The control group received a list of keywords. When students were asked to draw and describe the process in their own style and to reply to multiple-choice questions, the three iconographic approaches equally improved the overall outcome of the tests (relative to keywords). Students found the three approaches equally useful but, when asked to select a preferred style, they largely favored a realistic-schematic style. When students were asked to annotate “raw” realistic images, both keywords and schematic representations failed to prepare them for this task. We conclude that supplementary images facilitate the comprehension process and despite their visual clutter, realistic representations do not hinder learning in an introductory course.  相似文献
