This study employed eye-tracking technology to examine how students with different levels of prior knowledge process text and data diagrams when reading a web-based scientific report. Students’ visual behaviors were tracked and recorded when they read a report demonstrating the relationship between the greenhouse effect and global climate change in 2 diagrams and 4 textual sections. Based on the pretest scores, 13 participants were categorized into high and low prior knowledge (PK) groups. Eye-tracking measures including the total reading time, total fixation duration, and total regression number on each area of interest of the 2 groups were compared. A heat map was further used to show the overall visual distribution of each group. In addition, the inter-scanning transitions between the textual and graphical information of the 2 groups were compared and further confirmed by the patterns of the scan paths. The results revealed that overall students spent more time reading the textual than the graphical information. The high PK students showed longer fixation durations and more regressions on the graphics than the low PK students. Meanwhile, the high PK students showed more inter-scanning transitions than the low PK students not only between the text and graphics but also between the 2 data diagrams. This suggests that the high PK students were more able to integrate text and graphic information and inspect scientific data which is essential for online inquiry learning. This study provides eye-tracking evidence to show that low PK students have difficulties integrating scientific diagrams with expository texts and inspecting scientific data diagrams that are commonly shown in websites. Suggestions are made for future studies and instructional design for online inquiry-based science learning.  相似文献

This study examined whether children’s reading rate, comprehension, and recall are affected by computer presentation of text. Participants were 60 grade five students, who each read two expository texts, one in a traditional print format and the other from a computer monitor, which used a common scrolling text interface. After reading each text, participants were asked to recall as much as they could from what they had read and then answered questions that measured text recall and comprehension. Children took more time to read the passage and recalled more of the text material that they had read from the computer monitor. The benefit of computer presentation disappeared when efficiency variables, which take time into account, were examined. Children were, however, more efficient at comprehending text when reading from paper. The results suggest that children may take more time to read text on computer screens and that they are more efficient when reading text on paper.  相似文献

Two questions regarding signals’ influence on memory were examined. First, the relationship between headings and text was manipulated to determine whether headings serve as visual cues, directing readers to recall all subsequent information, or content-specific cues, directing readers to recall only to certain information. Second, distance between headings and signaled information was manipulated to determine the extent to which headings focus readers’ recall. College students read a multiple-topic expository text. Free recall for main topics was facilitated by being related to headings and being close to headings and inhibited by being unrelated to headings and distant from headings. Conditional recall (recall of subordinate information pertaining to a main topic) was not affected by either relatedness of heading or distance. Results are consistent with research showing signals’ mixed influence on recall and suggest relation and distance as factors to consider when writing and reading exposition.  相似文献

Our purpose was to compare the effect of two types of textual semantic coherence — causal and teleological — on the organization of the mental representation elaborated after reading by learners with different levels of prior knowledge. Beginners, Intermediates and Advanced in computer domain read either the causal or the teleological version of a text describing three functions of a text editor, then performed a cued recall and a recognition task. We assumed that Advanced learners build a mental representation of the domain organized in a hierarchical goal/sub-goals structure, whereas Beginners and Intermediates have a mental representation organized in a causal path. If this is so, the results should indicate a significant interaction between prior knowledge and the semantic coherence of the texts: for the Advanced learners, recall and recognition of the teleological text should be better, whereas for the Beginners and Intermediates, the reverse was expected. As we assumed, results indicated that a teleological organization of textual information facilitated the comprehension of Advanced participants while a temporal-causal organization facilitated the comprehension of Beginner and Intermediate participants. The Construction-Integration model of Kintsch (1988, 1998) was used to, simulate the recall results and to reproduce the effect of prior knowledge on the retrieval of textual information.  相似文献

The authors examined whether relevance instructions compensate for differences in verbal ability on measures of reading time, text recall, and sentence recognition. College students (n = 81) with higher and lower verbal ability were assigned randomly to 1 of 2 relevance-instruction conditions before reading a text. They asked participants in each condition to focus on different categories of information within the same text. Relevant information took longer to read and was recalled and recognized better than nonrelevant information. Readers with higher verbal ability read faster and recalled and recognized more information correctly than did those readers with lower verbal ability. Results support the noncompensatory hypothesis, which states that relevance instructions and verbal ability make independent contributions to resource allocation and learning. Readers with lower verbal ability may need additional support even when given prereading relevance instructions.  相似文献

ABSTRACT

The present research tested the hypothesis that the reading of science text can create new misconceptions in students with incongruent prior knowledge, and that these new misconceptions will be similar to the fragmented and synthetic conceptions obtained in prior developmental research. Ninety-nine third- and fifth-grade children read and recalled one of two texts that provided scientific or phenomenal explanations of the day/night cycle. All the participants gave explanations of the phenomenon in question prior to reading one of the texts and after they read it. The results showed that the participants who provided explanations of the day/night cycle at pretest incongruent with the scientific explanation recalled less information and generated more invalid inferences. An analysis of the participants’ posttest explanations indicated that these readers formed new misconceptions similar to the fragmented and synthetic conceptions obtained in developmental research. The implications of the above for text comprehension and science education research are discussed.  相似文献

Students search the Web frequently for many purposes, one of which is to search information for academic assignments. Given the huge amount of easily accessible online information, they are required to develop new reading skills and become more able to effectively evaluate the reliability of web sources. This study investigates the distribution of their visual attention while reading webpages using eye-tracking methodology. The aim was to examine whether information received differential attention depending on the reliability of the source and whether the individual characteristics of topic-specific prior knowledge and epistemic beliefs moderated their visual behavior during reading. Factual knowledge after reading was also examined. Forty-nine university students read four webpages providing verbal and graphical information about the universal validity of the central dogma of molecular biology, which varied for reliability. Indices of first-pass and second-pass reading or inspection were used to trace the processing of information within each page. Findings revealed that readers made an implicit source evaluation as they spent a longer time inspecting the pictures about the more and less familiar information within the most reliable source during the immediate, more automatic, processing. In addition, topic-specific epistemic beliefs moderated this processing as readers with more availing convictions about knowledge attended more the information provided in pages that required more discernment. Moreover, readers increased their factual knowledge of the topic after reading. Educational implications are outlined.  相似文献

Three experiments are reported that investigate the cognitive processes underlying contextual and isolated word reading. In Phase 1, undergraduate participants were exposed to 75 target words under three conditions. The participants generated 25 words from definitions, read 25 words in context and read 25 in isolation. In Phase 2, volunteers completed either an explicit recall task (Experiment 1), an implicit word stem completion task (Experiment 2) or both tasks (Experiment 3). Our findings provide converging evidence that contextual and isolated word reading elicit different patterns of cognitive processing. Specifically, Experiments 1–3 demonstrated that words read in context were remembered similarly to words generated from definitions: words from both conditions were recalled more frequently in the surprise memory task and selected less often to complete the word stems in the implicit memory task. The opposite pattern was noted for words read in isolation. Reading in context is discussed in terms of its greater reliance on semantic processing, whereas isolated word reading is discussed in relation to perceptually driven processes.  相似文献

This paper reports a thorough investigation of reading habits and activities which may require skills used in prose recall tasks as they occur in the everyday lives of adults. Over the space of five weeks, fifty‐four participants (18 young, aged 18‐32; 18 middle, aged 40‐54; 18 older, aged over 62) kept structured diaries in which they indicated how they spent their time, as well as the specific materials they had read and how long they had spent reading each item. Analyses were performed on each of 23 reading variables and 20 activity variables. Part I of this paper considers whether there were age and vocabulary differences in activities. Results indicate that while such differences exist, primarily in the amount of time spent reading, everyday activities and reading habits were also related to the requirements of daily life‐‐school, employment, retirement. Part II uses a cluster analysis of the data to demonstrate that the patterning of everyday activities was influenced more by current schooling and career factors than by the age and vocabulary level of the participants. Part II also considers the ecological validity of prose recall studies by examining the frequency of activities similar to laboratory‐style prose recall tasks and finds that such activities have a very low incidence in the everyday lives of adults.  相似文献

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general.  相似文献

This study examines how high school students use diagrams and summaries during reading and the effects of such on comprehension. The roles of verbal and spatial ability are also examined. Seventy-four Year 7 (13-year-old) students each read a text presented on a computer screen. The text was presented one sentence at a time and subjects could call up a diagram or content-equivalent summary of the main ideas of the text at any time. Time to read the sentences and the adjunct aids was controlled by the subject and recorded by the computer. In addition, the computer kept a record of where in the text subjects made a text-to-aid move. After reading, the subjects completed a 10-minute filler task and then produced free recalls of the text. The free recalls were examined for the inclusion of details and main ideas. Path analyses showed a significant direct effect of verbal ability on the recall of details and main ideas as well as a significant indirect effect through time on diagram. Spatial ability was not found to have any effect on recall, either directly or indirectly. Analyses of text-to-diagram moves showed more inspections in the first few sentences followed by an essentially random inspection pattern. Instructional implications are discussed.  相似文献

This experiment addressed the question of how headings influence readers' memories for text content. College students read and recalled a 12-topic expository text. Half of the participants were trained to construct a mental outline of the text's topic structure as they read and then use their mental outlines to guide their recall attempts. The remaining participants did not receive such training. Half of the participants read a text containing headings before every subsection; the other half read the same text without headings. The results were that participants who received training and/or read the text with headings remembered text topics and their organization better than participants who received no training and read the text without headings. The results support the hypothesis that signals induce a change in readers' strategies for encoding and recalling text.  相似文献

In this study, we examined the conditions under which readers are able to transfer revised knowledge as a result of reading refutation texts (i.e. texts that explicitly state and refute a misconception). Across three experiments, participants read refutation texts that addressed socioscientific and nonsocioscientific issues as well as transfer texts that were designed to reactivate the misconceptions addressed in refutation texts. In Experiments 1 and 2, the results indicate that reading a refutation text reduces interference from the misconception as participants read the transfer texts in close temporal distance, even when the misconception is reactivated. In Experiment 3, the results indicate that participants reading refutation texts could not transfer revised knowledge when the temporal distance between refutation texts and transfer texts increased. Students’ performance on pretest and posttest questionnaires also suggest that reading the refutation texts facilitated knowledge revision prior to transfer. We discuss the findings in the context of the Knowledge Revision Components Framework.  相似文献

Learning often involves integration of information from multiple texts. The aim of the current study was to determine whether relevant information from previously read texts is spontaneously activated during reading, allowing for integration between texts (experiment 1 and 2), and whether this process is related to the representation of the texts (experiment 2). In both experiments, texts with inconsistent target sentences were preceded by texts that either did or did not contain explanations that resolved the inconsistencies. In experiment 1, the reading times of the target sentences introducing inconsistencies were faster if the preceding text contained an explanation for the inconsistency than if it did not. This result demonstrates that relevant information from a prior text is spontaneously activated when the target sentence is read. In experiment 2 free recall was used to gain insight into the representation after reading. The reading time results for experiment 2 replicated the reading time results for experiment 1. However, the effects on reading times did not translate to measurable differences in text representations after reading. This research extends our knowledge about the processes involved in multiple text comprehension: Prior text information is spontaneously activated during reading, thereby enabling integration between different texts.  相似文献

Reading with Orthographic and Segmented Speech (ROSS) programs use talking computers to deal with deficits in word recognition and phonological awareness. With ROSS, children read stories on a computer screen. Whenever they encounter a word they find difficult, they can request assistance by targeting the word with a mouse. The program highlights the word in segments and then pronounces the segments in order. In previous studies, children improved in reading, but children with relatively lower initial phonological awareness (PA) gained less than the others. In order to maximize the benefits from ROSS for all children, the current study aimed to improve PA before and while reading with ROSS, by using some programs based on theAuditory Discrimination in Depth method (Lindamood and Lindamood 1975), and others focusing on phoneme manipulation with speech feedback for all responses. The study compared the effects of this training with training in Comprehension Strategies (CS) based on Reciprocal Teaching techniques (Palincsar and Brown 1984), among second- to fifth-grade students with problems in word recognition. While both groups received equal instructional time in small-groups and with the computer, the groups differed in how much time they spent reading words in context. Whereas PA children spent half their computer time on PA exercises involving individual words and half reading words in context with ROSS, the CS group spent all their computer time reading words in context with ROSS. Both groups made significant gains in decoding, word recognition, and comprehension; however the PA groups gained significantly more than the CS group on all untimed tests of phoneme awareness, word recognition, and nonsense word reading. The CS children performed better on a test of time-limited word recognition; they also achieved higher comprehension scores, although only while reading with a trainer. The PA children’s improved decoding skill led to greater accuracy, but slower responses with difficult words, after one semester’s training.  相似文献

This study examines the moderating effects of a situational factor (i.e., text type) and an individual factor (i.e., subject-matter knowledge) on the relation between depth of processing and performance. One-hundred and fifty-one undergraduates completed measures of subject-matter knowledge, read either an expository or persuasive text about the existence of extraterrestrials while thinking aloud, and then completed a passage recall task and an open-ended task. Results indicated that the relation between depth of processing and the open-ended tasks was moderated by the type of text participants read (i.e., expository or persuasive). Moreover, there was a significant interaction between the passage recall measure and open-ended task for depth of processing and type of text.  相似文献

The experiment reported here explored the importance of engaging 4-year-old children’s interest in the print itself during storybook reading. We explored the effect of computer animation of the print in order to draw the child’s attention to each word as it was read. We also investigated the influence of illustrating that not all visual displays are readable print on the child’s print knowledge. The measures of interest were print concept knowledge and early reading skill. Results indicated that simply drawing children’s attention to the print during shared reading was insufficient to facilitate children’s learning of print conventions, but this attention to print while hearing stories read did improve children’s letter reading. The child’s active engagement with the print during shared story reading led to further improvements in written language skills, as illustrated by gains in knowledge about print concepts.  相似文献

In this study, we examine the effect of background knowledge and local cohesion on learning from texts. The study is based on construction–integration model. Participants were 176 undergraduate students who read a Computer Science text. Half of the participants read a text of maximum local cohesion and the other a text of minimum local cohesion. Afterwards, they answered open-ended and multiple-choice versions of text-based, bridging-inference and elaborative-inference questions. The results showed that students with high background knowledge, reading the low-cohesion text, performed better in bridging-inference and in elaborative-inference questions, than those who read the high-cohesion text. Students with low background knowledge, reading the high-cohesion text, performed better in all types of questions than students reading the low-cohesion text only in elaborative-inference questions. The performance with open-ended and multiple-choice questions was similar, indicating that this type of question is more difficult to answer, regardless of the question format.  相似文献

We examined text memory in children with word reading deficits to determine how these difficulties impact representations of text meaning. We show that even though children with poor word decoding recall more central than peripheral information, they show a significantly bigger deficit relative to controls on central than on peripheral information. We call this the centrality deficit and argue that it is the consequence of insufficient cognitive resources for connecting ideas together due to these children’s resources being diverted from comprehension to word decoding. We investigated a possible compensatory mechanism for making these connections. Because a text representation is a synthesis of text information and a reader’s prior knowledge, we hypothesized that having knowledge of the passage topic might reduce or eliminate the centrality deficit. Our results support this knowledge compensation hypothesis: The centrality deficit was evident when poor readers did not have prior knowledge, but was eliminated when they did. This presents an exciting avenue to pursue for possible remediation of reading comprehension in children with word identification difficulties.  相似文献

The purpose of this mixed methods study was to investigate how relevance instructions influence readers’ personal reading intentions, reading goals, text processing, and memory for text. Undergraduates (n = 52) were randomly assigned to one of three pre-reading relevance instruction conditions that asked them to read from a perspective or to read for understanding. Experimental results showed that information was read slower and remembered better when it was relevant. However, some readers spent more time reading irrelevant information, whereas others spent less time reading this information. Post-reading interviews were analyzed to explain these reading time differences. The interview data indicated that relevance instructions influenced readers’ goals and the strategies they used to meet those goals. The data sets were complementary: the quantitative data indicated differences in reading time and recall, and the qualitative data allowed us to explain why these differences occurred. These data revealed three distinct reader profiles within and across conditions, and demonstrate how relevance instructions affect reader goals, processing, and comprehension.  相似文献
