Does the presentation style of questions inserted into text influence understanding and retention of science concepts?

The purpose of this research was to determine the relative effects of the presentation style of questions inserted into text materials for students in university introductory biology. The sample was randomly assigned to seven treatment groups of approximately equal size and read a 2,354-word passage on bacterial adaptations taken from a popular university general biology textbook. Experimental treatment groups read the same passage with (1) questions placed at the beginning of selected paragraphs and with the questions presented with (2) underlining, (3) in uppercase, (4) set above the paragraph, (5) underlined and set above, and (6) set above in uppercase respectively. The criterion variable was a 20-item multiple-choice exam with five possible answers per question given once to all students immediately after they read the passage and again exactly four weeks later. Presentation strategy groups were contrasted against the reading without questions groups. Four of the six groups reading with questions at the beginning of the paragraph scored significantly higher on the test given immediately after the reading than the group reading without questions. There were no significant differences between any of the group scores for the test given four weeks after reading. Other differences in results between these strategies and implications for text writers are discussed.     

On inserting questions before or after segments of text

It has been concluded in all major reviews of adjunct question research that a group given questions after related text segments (postquestions) yields greater recall than a group given questions before related text segments (prequestions) or one not given any questions at all. However, closer examination of the earlier research and an analysis of recent research reveals that for certain types of verbatim questions and for certain high level questions, postquestions produce recall equivalent to or less than prequestions. Moreover, in many studies wherein postquestions exceed prequestions, the postquestion group equals the reading-only control group in recall of nonquestioned (incidental) material. Hence, despite frequent pronouncements to the contrary, no firm recommendation can be made regarding the optimal placement of adjunct questions in text material.     

How word decoding skill impacts text memory: The centrality deficit and how domain knowledge can compensate

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.     

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.     

Role of epistemological understanding and interest in interpreting a controversy and in topic-specific belief change

This study focuses on the influence of high school students’ (10th and 11th grade) epistemological understanding and topic interest on their interpretation of a dual-position expository text about genetically modified food, as well as on the change in their beliefs about the topic. After reading, students were given different tasks: (1) to write a conclusion for the text, which presented two opposing positions but lacked an overall concluding paragraph, (2) to write personal comments on the text, (3) to answer questions on conceptual understanding, and (4) to rate their interest in the text. Participants were also asked to rate their beliefs about transgenic food before and after reading the text. The findings show the effects of students’ level of epistemological understanding when writing conclusions to the text, and commenting on (a) the role of science and scientists’ work with respect to nature, (b) the need for further scientific investigation, and (c) the effective value of transgenic food production. Students’ topic interest affected their answers to the questions on the text arguments and their text-based interest. In addition, after reading, a change emerged in students’ beliefs about the topic in relation to their epistemological understanding.     

从阅读到“悦”读

在英语教学中“听说读写”是“四大要素”,而阅读能力的培养更是英语教学中最基本、最重要的内容。先看问题后读文章,生活常识很重要,议论文找出论点很重要,查找主要事实或特定细节,从而将阅读转化为“悦”读。     

Do bilingual children read words better in lists or in context?

The aim of this study was to determine whether 11-year-old children in Singapore, from English Dominant or English Non-Dominant backgrounds, read better orally when words were presented in list or text. The children read words in passage and in list form presented in counterbalanced order. In a study of good, average and poor readers, Nicholson (1991) found that context was of more benefit to poorer readers and to younger readers. With the English Non-Dominant readers in the present study regarded as less proficient readers of English, these children should be expected to show the greatest gains from passage presentations. Error analyses showed that English Non-Dominant readers performed less well in list readings relative to text readings, while the English Dominant readers produced no difference in performance for these conditions. This indicates that readers with less exposure to English relied more on contextual information than the more experienced readers. Thus, Goodman's (1965) idea of enlightened guessing was again questioned in this study for the case of bilingual readers. Additionally, reading miscues were found to vary in type according to whether the same words were being read in list or in context.     

How prior knowledge affects word identification and comprehension

While prior knowledge of a passage topic is known to facilitate comprehension, little is known about how it affects word identification. We examined oral reading errors in good and poor readers when reading a passage where they either had prior knowledge of the passage topic or did not. Children who had prior knowledge of the topic were matched on decoding skill to children who did not know the topic so that the groups differed only on knowledge of the passage topic. Prior knowledge of the passage topic was found to significantly increase fluency and reduce reading errors, especially errors based on graphic information, in poor readers. Two possible mechanisms of how prior knowledge might operate to facilitate word identification were evaluated using the pattern of error types, as was the relationship of errors to comprehension. Implications of knowledge effects for assessment and educational policy are discussed.     

How generalization inferences are constructed in expository text comprehension

Three questions regarding adult readers’ processing of generalization inferences (conceptually broad statements that subsume several specific statements) are investigated. College students (N = 193) read expository texts containing target statements that were consistent, inconsistent, or off-topic in relation to a generalization implied by one paragraph. Reading times were faster for consistent than inconsistent statements and faster for inconsistent than off-topic statements, indicating adult readers construct generalization inferences online during initial reading of a text and that the inference they construct is relatively narrow in scope. This pattern of faster reading time for consistent sentences occurred under different reading goals, suggesting generalization inferences are a pervasive component of expository text comprehension.     

语篇语言学及语篇意识在翻译中的体现

英语词汇在语言使用中是以语篇的形式出现的，语篇语言学有其自身的特点。翻译时应该把语篇当作一个整体来看待，语篇虽然是由一个个段落、一个个句子组成，但是它不是语句的机械叠加，而是一个有机的、动态的组合。连行翻译时，在把握住原文语篇特点的同时，译者还要对每一节、每一段给予足够的关注，认真理清语篇的发展脉络，层次及句与句之间的链接。虽然译者翻译的是一个个的词、词组和句子，但必须意识到，只译好了一个句子，并不等于完成了翻译任务。要将句子集合起来组成句群、段落直到语篇。了解文化与语篇意识，将语篇意识应用到英语翻译中，可进一步提高翻译的准确性。     

The Nature of the Refutation Text Effect: An Investigation of Attention Allocation

ABSTRACT

Students often hold misconceptions that conflict with scientific explanations. Research has shown that refutation texts are effective for facilitating conceptual change in these cases (Guzzetti, Snyder, Glass, & Gamas, 1993). The process through which refutation texts have their effect is not clear. The authors replicated and extended previous research investigating cognitive processes involved in the refutation text effect. Undergraduates read either a refutation or an expository text on seasonal change. Individual reading times were recorded. Participants’ conceptions were measured at pretest, posttest, and delayed posttest. Results showed that readers spent less time reading the refutation paragraph compared to the expository paragraph. The refutation text group had fewer misconceptions at posttest. These findings suggest that refutation text processing differences mirror similar findings in the attention literature, which may account for their effectiveness.     

英汉论说文体段落组织的差异性分析

由于思维模式的差异，英汉段落在组织上体现出明显的差异。在统一性的问题上，汉语段落显然要宽容得多，螺旋式的展开方式使汉语段落可以“迂回而言它”；英语段落则单刀直入，不容许任何偏离主题的句子出现，内容上高度统一。连贯性在汉语中更多地以“意合”的方式来体现；英语段落则使用显性手段明确地做出标记。多数汉语段落的完整性要跨自然段来实现；英语的自然段则往往就是意义段甚至可以等同于小文章，结构上很完整，圆满地交待清楚主题思想。     

Training students to process text with adjunct aids

Hypotheses about how readers learn from text augmented by objectives or by adjunct postquestions were operationalized by training students to use specific processes while reading. Achievement on a one-passage and on a four-passage curriculum was analyzed using regression analyses to identify treatment effects and aptitude-treatment interactions. Training students to use theoretically appropriate processes associated with objectives or adjunct postquestions generally reduced aptitude-treatment interaction effects, but it did not yield the expected increments in learning compared to placebo groups. Discussion centers on a pointer effect prompted by objectives and postquestions that relates to aptitude. The methodological difficulties and theoretical advantages of operationalizing students' cognitive responses to instructional stimuli by training are also described.     

Textual and graphical refutations: Effects on conceptual change learning

Refutation text is potentially more effective than standard text for conceptual change. Learning from text and graphic is also potentially superior to learning from text alone. In two studies, we investigated the effectiveness of both a refutation text and a refutation graphic for promoting high school students’ conceptual change learning about season change, as well as their metacognitive awareness of conceptual conflict and knowledge revision. In both studies, participants were randomly assigned to one of four conditions: (1) standard text with standard graphic, (2) standard text with refutation graphic, (3) refutation text with standard graphic, or (4) refutation text with refutation graphic. Both studies had a pretest, immediate post-test, and delayed post-test design and involved students with an initial common misconception about the causes of season change. In Study 2, explicit relevance instructions to observe the important illustration were given to the participants. In both studies, refutation text with refutation graphic was not more beneficial than other instructional materials, either at immediate or delayed post-test. In Study 1, more stable conceptual change learning emerged in readers of the refutation text with standard graphic compared to readers in the control condition. In Study 2, readers of the standard text with refutation graphic performed as well as readers of the refutation text with standard graphic. In addition, more readers of the refutation text with either graphic showed metacognitive awareness of their knowledge change compared to readers in the control condition. Educational implications underline the importance of relevance instructions for guiding readers toward the graphic and of the design of text-graphic pairing to sustain knowledge revision.     

What predicts adult readers’ understanding of STEM texts?

The current study examined the relations among key variables that underlie reading comprehension of expository science texts in a diverse population of adult native English readers. Using Mechanical Turk to sample a range of adult readers, the study also examined the effect of text presentation on readers’ comprehension and knowledge structure established after reading. In Study 1, ratings of situational interest, select reading background variables, and select measures of readers’ knowledge structure accounted for significant variance in comprehension. In Study 2, the knowledge structure metrics of primacy, recency, and node degree as well as several text ratings were found to be comparable across text presentation formats. Participants who read the text sentence-by-sentence obtained higher scores on measures of comprehension and provided higher ratings of situational interest than those who received the whole paragraph text at once. Knowledge structure measures for the sentence-by-sentence and paragraph formats were similar (68% overlap). We discuss implications for future research examining factors that underlie the successful comprehension of science texts.     

Patterns of inverted reading and subgroups in dyslexia

Reading performance of 46 poor readers was compared with that of 20 normal control readers. All subjects were second grade children. In Experiment 1 two matching word lists were presented under two conditions: one version of the test was read in the upright position and the other inverted. In Experiment 2 the eye movements of all subjects were recorded during reading of two meaningful sentences in the normal and inverted position. While the controls were negatively influenced by inversion of the text, the poor readers showed a variety of responses. Overall, the poor readers showed a slight tendency to be better at reading in the inverted position when the text must be scanned from right to left. An individual analysis of the data revealed that in 28.3% of the poor readers inverted reading improved performance at least 15 %, a phenomenon found in none of the controls.     

Statement-Pie: a strategy to improve the paragraph writing skills of adolescents with learning disabilities

This study investigated the effects of teaching a metacognitive text structure strategy upon the paragraph writing skills of eighth-grade students with learning disabilities. The technique, called Statement-Pie (Hanau, 1974), teaches students to understand the relationship of supporting details to a main idea. Four students were taught to use an outline as a paragraph planning guide, which they then used to convert information into written expository paragraphs. All subjects reached instructional outcome criterion on the writing of comparison/contrast and sequence paragraphs. One week after reaching mastery in the special education classroom, students generalized their paragraph writing skills to other teachers and to different classrooms. The results of this investigation indicate that when provided with direct, intensive instruction in a text structure strategy, adolescents with learning disabilities can improve their skills in paragraph writing.     

The Influence of Critical Reading Orientation on External Strategy Use during Expository Text Reading

This study examined the influence of critical reading orientation on use of external strategies such as note‐taking and underlining while reading an expository text. In two experiments, undergraduate students were asked either to review an article on a linguistic policy (critical reading) or to summarise it (less‐critical reading). Experiment 1 indicated that, when permitted to do so, the majority of students used note‐taking and/or underlining strategies for critical reading as well as for less‐critical reading. In Experiment 2, an analysis of think‐aloud protocols, notes, and underlines revealed that critical readers produced more critical notes/underlines and fewer summary notes than did less‐critical readers. Also, critical readers substantially increased their production of critical notes/underlines over the course of reading and decreased highlightings, whereas less‐critical readers increased summary notes and decreased highlightings.     

Development of software to support argumentative reading and writing by means of creating a graphic organizer from an electronic text

This paper describes the development of a software program that supports argumentative reading and writing, especially for novice students. The software helps readers create a graphic organizer from the text as a knowledge map while they are reading and use their prior knowledge to build their own opinion as new information while they think about writing their essays. Readers using this software can read a text, underline important words or sentences, pick up and dynamically cite the underlined portions of the text onto a knowledge map as quotation nodes, illustrate a knowledge map by linking the nodes, and later write their opinion as an essay while viewing the knowledge map; thus, the software bridges argumentative reading and writing. Sixty-three freshman and sophomore students with no prior argumentative reading and writing education participated in a design case study to evaluate the software in classrooms. Thirty-four students were assigned to a class in which each student developed a knowledge map after underlining and/or highlighting a text with the software, while twenty-nine students were assigned to a class in which they simply wrote their essays after underlining and/or highlighting the text without creating knowledge maps. After receiving an instruction regarding a simplified Toulmin’s model followed by instructions for the software usage in argumentative reading and writing along with reading one training text, the students read the target text and developed their essays. The results revealed that students who drew a knowledge map based on the underlining and/or highlighting of the target text developed more argumentative essays than those who did not draw maps. Further analyses revealed that developing knowledge maps fostered an ability to capture the target text’s argument, and linking students’ ideas to the text’s argument directly on the knowledge map helped students develop more constructive essays. Accordingly, we discussed additional necessary scaffolds, such as automatic argument detection and collaborative learning functions, for improving the students’ use of appropriate reading and writing strategies.
