Effect of in-app components,medium, and screen size of electronic textbooks on reading performance,behavior, and perception

Although many app-based textbooks are available for students, reading have not been thoroughly outlined. This study aimed to understand how changes from paper to electronic textbooks have affected the academic reading task, investigate student users’ perceptions of in-app components and screen sizes, and identify issues affecting in-app components and task requirements. A mixed factorial design experiment was employed. Results showed that there were no significant changes in comprehension and time spent reading between print text and the iPad. Yet, student highlighting, notetaking, and reading behavior and perception significantly changed based on condition. In addition, students struggled to use in-app components and found them frustrating especially when accounting for sentence splitting. The findings presented can assist in understanding the changes in student reading behavior, which can be used to improve interface design of future e-textbooks.     

Reading Motivation: Multidimensional and Indeterminate.

The Motivations for Reading Questionnaire (MRQ) contains 54 items that are posited to tap 11 dimensions of reading motivation. The structural validity of the MRQ was investigated with 2 samples: (a) 328 students in Grades 3-5 from 2 suburban mid-Atlantic elementary schools and (b) 735 students in Grades 3-5 in 2 suburban southwestern elementary schools. With confirmatory factor analyses (CFAs), the theoretical 11-factor structure did not adequately fit the data in either sample. Subsequently, exploratory factor analyses found 8 factors for each sample with 6 factors defined by only 3 or 4 common items. However, a double CFA cross-validation found an inadequate fit for both samples. Given these results, the authors suggest that the MRQ be revised.

Annotations and the collaborative digital library: Effects of an aligned annotation interface on student argumentation and reading strategies

Recent research on annotation interfaces provides provocative evidence that anchored, annotation-based discussion environments may lead to better conversations about a text. However, annotation interfaces raise complicated tradeoffs regarding screen real estate and positioning. It is argued that solving this screen real estate problem requires limiting the number of annotations displayed to users. In order to understand which annotations have the most learning value for students, this paper presents two complementary studies examining the effects of annotations on students performing a reading-to-write task. The first study used think-aloud protocols and a within-subjects methodology, finding that annotations appeared to provoke students to reflect more critically upon the primary text. This effect was particularly strong when students encountered pairs of annotations presenting different viewpoints on the same section of text. Student interviews suggested that annotations were most helpful when they caused the reader to consider and weigh conflicting viewpoints. The second study used a between-subjects methodology and a more naturalistic task to provide complementary evidence that annotations encourage more reflective responses to a text. This study found that students who received annotated materials both perceived themselves and were perceived by instructors as less reliant on unreflective summary strategies than students who received the same content but in a different format. These findings indicate that the learning value of an annotation lies in its ability to provoke students to consider and weigh new perspectives on the primary text. When selected effectively, annotations provide a critical scaffolding that can support students’ critical thinking and argumentation activities. Collaborative digital libraries and applications for the Web 2.0 should be designed with this learning framework in mind.

基于表示学习和深度森林的长链非编码RNA编码短肽预测模型

长链非编码RNA（lncRNA）中的小开放阅读框（sORFs）能够编码长度不超过100个氨基酸的短肽。针对短肽预测研究中lncRNA中的sORFs特征不鲜明且高可信度数据尚不充分的问题,提出一种基于表示学习的深度森林（DF）模型。首先,使用常规lncRNA特征提取方法对sORFs进行编码;其次,通过自编码器（AE）进行表示学习来获得输入数据的高效表示;最后,训练DF模型实现对lncRNA编码短肽的预测。实验结果表明,该模型在拟南芥数据集上能够达到92.08%的准确率,高于传统机器学习模型、深度学习模型以及组合模型,且具有较好的稳定性;此外,在大豆与玉米数据集上进行的模型测试中,该模型的准确率分别能达到78.16%和74.92%,验证了所提模型良好的泛化能力。

阅读附带习得词汇国外研究之初探

词汇曾一度被认为是外语教学中的"灰姑娘"。近些年来,人们才逐渐认识到其在语言发展中的重要性,并就词汇习得问题作了很多研究。词汇习得又分为刻意学习和附带习得。词汇附带习得被认为是掌握大量单词的重要途径,极受重视。而阅读则是公认的词汇附带习得的主要途径之一。总体来看,这方面的研究在国内还不是很多;国外的研究数量多,且多属实证研究,有很多可借鉴之处;而且,国内大多数相关研究是对国外实证研究的简单重复,或是对国外相关理论的探讨或思辨,故本文主要关注于国外阅读中词汇附带习得的研究,以期读者可以借以了解国外该研究领域的现状。
