Previous research has shown that pictures can be effective in enhancing text memory. For example, Waddill and McDaniel (1992) found that pictures depicting detail information in an expository text effectively enhanced recall of those details and pictures depicting relational information effectively enhanced recall of those relations. However, the research on picture enhancement effects raises the question of whether the mnemonic value of pictures is simply a by‐product of having drawn attention to parts of the text through selective repetition of text content. The present study addressed the question by comparing the relative effectiveness of pictures versus simple verbal captions in promoting text memory. The results replicated the Waddill and McDaniel (1992) pictorial enhancement effect. However, the results showed that repeating the targeted information in a verbal caption was as effective as providing a pictorial illustration, thus suggesting that repetition of text content rather than nonverbal pictorial illustrations produced the effect. The findings generalized across three texts that differed in the amount of spatial content they conveyed. 相似文献

Instructional pictures may be classified on the basis of how they convey meaning including classification as representational, analogical, or arbitrary (Gropper, 1963; Knowlton, 1966). Some previous reviews of picture effects have dealt with only the first category of pictures-that is, pictures that are isomorphic with the objects or concepts that they represent (Alesandrini, 1982; Levin and Lesgold, 1978). Other reviews have also considered arbitrary or non-representational pictures such as flowcharts and graphs (Levie and Lentz, 1982; Macdonald-Ross, 1977a). This article discusses research on all three types of pictures and considers how each type may play a crucial, yet different, role in the learning process. The focus is on picture effects in adult meaningful learning such as concept learning, learning from prose materials, and learning from expository text. 相似文献

Preservice teachers studied texts about three fundamentally important science concepts. They read versions with no analogy, versions with a simple analogy, and versions with an elaborate analogy. An elaborate analogy is one that consists of text and pictorial components in which similarities between the analog and the target concept are made explicit. Verbal and imagery processes combine to promote a mapping of conceptual features. The findings indicated that elaborate analogies improved the science knowledge and attitudes of preservice teachers by relating what is familiar to what is new. The findings are consistent with a constructivist view of learning science and suggest that science texts for preservice teachers should be adapted to take advantage of elaborate analogies in a systematic way. 相似文献

Learning from split-attention materials: Effects of teaching physical and mental learning strategies
Learners learn more from spatially separated text and pictures after they have been instructed to physically integrate these sources than without such an instruction. We investigated whether instructing learners to mentally integrate textual and pictorial information would yield similar results. Eighty-seven participants studied a picture with accompanying text about an electrical circuit. Text and picture were presented as spatially separated sources or in an integrated format. In the separated format, participants were instructed to use (1) a mental learning strategy, (2) a physical learning strategy, or (3) no learning strategy. Participants in the separated condition using a mental learning strategy and the integrated condition obtained higher recall and comprehension (but not causal inference) performance than participants in the separate conditions with the physical- or no learning strategy. This indicates that instructing learners to mentally integrate spatially separated text and pictures when studying split-attention material can be an effective learning strategy. 相似文献

How analogies foster learning from science texts 总被引：1，自引：0，他引：1
This article provides an introduction to extended text-based analogies used for instructional purposes in science textbooks. A theoretical framework for understanding learning via extended analogies is discussed, and examples of extended textual analogies are provided. Research which provides direction in how to optimally use analogies in science instruction is reviewed. Characteristics of good analogies, types of learners who might benefit from the use of analogies, and kinds of learning which might be facilitated are discussed. The issue of possible misconceptions generated via instructional analogies is addressed, in conjunction with suggestions for remediation. Finally, recommendations for effective use of analogies in text are made, suggestions for instructional practices accompanying textual science analogies are provided and directions for future research are suggested. 相似文献

This paper reports two studies on comprehension of pharmaceutical texta containing pictorial and written instructions by mothers in rural Kenya. The subjects were asked to read and recall instructions for preparing and administering a solution for the treatment of dehydration due to diarrheal disease in children. A set of pictures describing the preparation procedure, together with written text instructions under two conditions, (a) original, as in the commercial product, and (b) revised, to include familiar terminology and explanations of some procedures, were presented to two groups of Kenyan mothers. The verbal protocols generated were transcribed and analyzed using propositional representation of instructional procedures.The results showed that mothers recalled the procedures for the preparation as in the pictures but not those presented in the written instructions. The written instructions were generally found to be difficult, with the original text being more difficult than the revised text. Any conflicting information between the written and pictorial instructions was resolved by selecting the familiar procedure. The information recalled from the revised text that was recalled was that which supported the procedures in the pictures. The results have implications for writing adequate pharmaceutical texts for users such that little room is left for misinterpretation. 相似文献

This paper describes an analogy classification framework used with high school chemistry textbooks. The framework takes into account aspects of past research into analogies in science education to allow for a systematic classification of textbook analogies based upon nine criteria including chemistry content area. Many of the 93 analogies classified described abstract chemistry concepts such as atomic structure and bonding, however, the frequent use of simple analogies, and the scarcity of stated limitations, are likely to create learning problems for students. In some textbooks, authors made use of margin spaces to include more analogies and these marginalised analogies often contained a pictorial component. Recommendations for further research into analogies in science education and possible methodological approaches are suggested. 相似文献

An experimental study with 60 students investigated the effects of including static or dynamic visuals in an expository text on a learning outcome and the use of learning strategies while working with those visuals. For the study, two illustrated and one text-only version of a computer-based learning text on an astrophysical subject were developed and served as the learning material. Considering the cognitive task demand in a learning test, we found significant differences between the illustrated versions and the text-only version, but not between the two illustrated ones. We used think-aloud protocols to examine the learning processes initiated by both types of visuals. The coding of the recorded learning activities was based on recent theories of learning strategies. The results for both types of illustrations indicate different frequencies in the use of learning strategies relevant for the learning outcome, and therefore indicate the contribution of the cognitive process quality for the supportive function of visuals. 相似文献

Visuo-spatial text adjuncts such as static or animated pictures, geographic maps, thematic maps, graphs, and knowledge maps that have been analyzed in the articles contained in this special issue provide complex pictorial information that complements the verbal information of texts. These spatial text adjuncts are considered as depictive representations that can support communication, thinking, and learning. An essential precondition of this supportive function is that the visuo-spatial displays interact appropriately with human visual perception and the individual's cognitive system, which is characterized by prior knowledge, cognitive abilities, and learning skills. Accordingly, effective learning with visuo-spatial text adjuncts can be fostered by instructional design and by adequate processing strategies, both dependent on sufficient understanding of how the human cognitive system interacts with these displays. Perspectives for further research in this area are provided. 相似文献

ABSTRACT The effect of instructional materials enhanced with textual metaphors versus graphical metaphors was investigated. In the text‐plus‐textual metaphor material, the learning content described computer programming logic patterns (i.e. sequence, selection and repetition control structures) in a generic text format, followed by expository examples in the form of textual metaphors. The text‐plus‐graphical metaphor material consisted of the generic text instruction with the expository examples replaced by graphical metaphors (pictures). A total of 37 adult learners attended one lecture and two tutorials to learn how to write programming algorithms. All of the participants completed Riding and Cheema's (1991) Cognitive Styles Analysis (CSA) to measure their position on two cognitive style dimensions: Wholist‐Analytic and Verbal‐Imagery. The participants were paired based on their similar CSA ratios. One participant from each pair was given the text‐plus‐textual metaphor treatment, while the other was given the text‐plus‐graphical metaphor treatment. The treatment groups were controlled for instructional format and cognitive style. These independent variables were used to test for their effect on learning abstract computer programming concepts. Performance, as measured by the difference between pre‐test and post‐test scores, was analysed using statistical means and the QUEST probability analysis program. Both methods show that graphical metaphors improve participants’ performance. They also show that the best performance is achieved by Verbalisers, given the graphical metaphor instructional material. 相似文献

The difficulties encountered by pupils and students when learning physics can often be explained by the differences that exist between their spontaneous ideas about the real world and how the scientist models this reality. How can children and adolescents be helped to better understand scientific ideas that could be of use to them? What is the role in learning and in teaching of: peer group interaction, different forms of representation (pictorial analogies, schemes, graphs), intelligent tutoring systems; etc? In this special edition there are a number of pieces of recent research of interest both to the researcher and to educator concerned with the development of knowledge and the teaching of the experimental sciences. 相似文献

The study compared the comprehension processes and outcomes obtained with refutation and expository text and their association with learning outcomes. After a knowledge pretest, undergraduate students read an extended expository text or a corresponding refutation text that addressed three potential misconceptions about the scientific concept of energy. Think-aloud, cued recall, and posttest data indicated that the positive impact of refutation text was more associated with comprehension outcomes than processes. Refutation text did not influence comprehension processes but facilitated valid inference generation in recall and minimized the negative effects of distortions on learning. The findings suggest the timing of the refutation text effect to be later, after reading, and its nature to be that of neutralizing the influence of any misconceptions on learning from text instead of changing them. 相似文献

The study examined whether the modality effect is caused by either high visuo-spatial load or a lack of temporal contiguity when processing written text and pictures. Students (N = 147) viewed pictures on the development of tornados, which were accompanied by either spoken or written explanations presented simultaneously with, before, or after the pictures. For verbal recall no modality effect was observed, whereas for transfer the influence of modality varied as a function of phonological working memory capacity. For pictorial recall the results showed a modality effect that was limited to simultaneous presentation, apparently in line with the temporal contiguity explanation. However, spoken simultaneous presentations were not superior to spoken sequential presentations, which contradicts the temporal contiguity explanation for the modality effect. Rather, it seems as if learners with simultaneous presentation of written text and picture concentrated more on the text and ignored the pictures, resulting in worse pictorial recall. 相似文献

Learning from expository text in computer-based instruction (CBI) was examined as a function of text density level (high,
low, or learner-controlled) and learner characteristics in achievement, attitudes, and reading ability. Low-density text was
found to be as effective for learning as high-density text, but was more popular among students and also reduced completion
time. The highest achievement was obtained in the learner-control condition, with low-ability readers showing a greater tendency
to select high-density text than did high-ability readers. Reading ability was also positively related to achievement in learning
from high-density computer text and to preferences for learning from CBI relative to print. Based on the resulte, use of low-density
text is suggested as a standard feature or learner-control option for CBI lessons. 相似文献

The objective of this study was to investigate the effects of three different screen sizes (small, medium and large) and two types of multimedia instruction (text only and text with pictorial annotation) on vocabulary learning. One hundred thirty‐five Korean middle school students learning English as a foreign language were randomly distributed into six groups and were given a pretest, a self‐study multimedia instruction, a posttest and a retention test online. The pretest, posttest and retention test were identical and included 30 vocabulary questions. Results show that the large screen multimedia instruction helped the students to learn English vocabulary more effectively than the small screen instruction as demonstrated on both the posttest and retention test. However, there was little difference in vocabulary learning between the text‐only and text‐with‐pictorial annotation instructions. Although visual perception can be influenced by each learner's expectations and knowledge, using a smaller screen for instruction causes more challenges for learners to perceive and comprehend vocabulary learning. 相似文献

The hypothesis that narrative text structure would be more interesting than expository text structure, and would therefore motivate more learning, was tested using an experimental design. Five classes of secondary school students read a history textbook chapter written in conventional expository style, and another five classes read a narrative version in which the same subject matter was embedded in a story involving fictional characters. All students also received instruction from their teachers. Contrary to prediction, the two groups did not differ significantly on the achievement posttest. Both groups also had similarly positive attitudes toward the text version they read, although in a face-to-face comparison the majority of the students preferred the narrative version. Recommendations for further tests of the hypothesis are offered. 相似文献

Learning strategies for making sense out of expository text: The SOI model for guiding three cognitive processes in knowledge construction 总被引：7，自引：0，他引：7
Richard E. Mayer 《Educational Psychology Review》1996,8(4):357-371
This article examines learning strategies that promote meaningful learning from expository text as evidenced by problem-solving transfer. The teaching of learning strategies involves decisions concerning what to teach, how to teach, where to teach, and when to teach. The teaching of learning strategies also depends on the teacher's conception of learners as response strengtheners, information processors, or sense makers. Three cognitive processes involved in meaningful learning are selecting relevant information from what is presented, organizing selected information into a coherent representation, and integrating presented information with existing knowledge. Finally, exemplary programs for teaching of learning strategies are presented. The most effective method for teaching students how to make sense out of expository text is for students to participate in selecting, organizing, and integrating information within the context of authentic academic tasks. 相似文献

New technologies allow the display of text, static visuals, and animations. Although animations are inherently attractive,
they are not always beneficial for learning. Problems may arise especially when animations modify the learner's cognitive
load in an unintended way. In two learning experiments with 40 and 26 university students, the effects of animated pictures
on knowledge acquisition were investigated. Some pictures displayed visual simulations of changes over time, whereas other
pictures could be manipulated by learners to represent different states in time. Results showed that manipulation pictures
had an enabling function for individuals with high learning prerequisites, whereas simulation pictures had a facilitating
function for individuals with low learning prerequisites. However, the facilitating function was not beneficial for learning,
because learners were prevented from performing relevant cognitive processes on their own. A careful analysis of the interrelation
between different kinds of cognitive load and the process of learning is therefore required. 相似文献

Social precursors to symbolic understanding of pictures were examined with 100 infants ages 6, 9, 12, 15, and 18 months. Adults demonstrated 1 of 2 stances toward pictures and objects (contemplative or manipulative), and then gave items to infants for exploration. For pictures, older infants (12, 15, and 18 months) emulated the adult's actions following both types of demonstration trials. For objects, infants did not emulate actions following either stance at any age. The findings suggest that infants enlist their imitative learning skills in the context of learning the conventions of action on pictorial symbols. The data are interpreted as pointing to the importance of social learning in developing an understanding of the referential function of pictorial symbols. 相似文献
