基于应用型本科人才培养的离散数学教学改革探讨

《离散数学》作为信息管理与信息系统专业核心课程之一,由于概念多、理论性强且抽象,教学时容易造成知识点散、教师满堂灌的局面,使学生学习时感到吃力,从而失去对课程学习的兴趣。文章从信息管理与信息系统专业应用型人才培养的角度,对离散数学进行教学改革,广泛全面地增加应用案例,使学生在学习后能应用所学理论解决一定的实际问题。     

元结的诗歌理论和诗歌创作

元结是鲜卑族拓跋氏的后裔,身上具备义勇纯真的北方草原民族的特点。在文学的价值取向上,趋向于质朴和慷慨,更多地强调文学经世致用的政治功能一面。在诗歌理论和创作上,他提倡古诗古乐府,反对近体流行调;提倡言志抒情,不重儒家诗教。有的讽谏之作言词犀利,态度狷狂,有的诗歌古朴直切,与“主文而谲谏”相左,在一定程度上突破了儒家诗论的藩篱,表现了出身拓跋氏的元结“不师孔丘”的一面。

Teacher support and academic engagement among EFL learners: The role of positive academic emotions

Academic engagement and teacher support, as two important factors in education, have been largely neglected in the research literature of English as a Foreign Language (EFL) and applied linguistics. Given the facilitative role of positive emotions in learning processes, this study aimed to examine their mediating role in the relationship between teacher support and academic engagement among Iranian EFL learners. The participants were 435 EFL freshmen randomly selected via multi-stage cluster sampling. The data were collected through previously validated measures. The results of structural equation modelling showed that perceived teacher support could directly and positively affect academic engagement. Additionally, positive emotions mediated the relationship between teacher support and academic engagement. Finally, some important implications and suggestions for further research are presented.     

Computer-based knowledge of results feedback in different delivery modes: Effects on performance,motivation, and achievement emotions

Immediate Knowledge of Results (KR) feedback at the task level may motivate test takers by showing that their answers matter. Appealing feedback cues may help to prevent negative emotions in lower performers who receive a higher amount of negative feedback. In this experiment, we varied the presence of KR feedback and the feedback delivery mode in a 1 × 5 between-subjects design (i.e., no feedback vs. text, color, sound, or animation feedback) to investigate effects on learning outcomes and affective-motivational measures. Our sample included 661 fifth and sixth graders who solved two computer-based multiple-choice science tests. First, students worked on an 18-item treatment test (with experimental feedback manipulation). Students repeatedly rated their effort, enjoyment, pride, and boredom during the test, as well as their expectancy of success and attainment value after the test. Subsequently, they worked on a posttest (without feedback) that assessed recall and near-transfer learning. All KR feedback conditions significantly increased recall, but there was no evidence for near-transfer learning. Feedback had a significant, negative effect on attainment value, whereas significant interactions between the feedback conditions and students’ treatment performance revealed that feedback effects on several affective-motivational dimensions (i.e., expectancy of success, enjoyment, pride, and boredom) were performance-dependent. Feedback benefited higher performers’ motivation and affect but showed negative effects on some affective-motivational measures for lower performers. The pattern of results indicated that color/sound/animation feedback may have reduced the effect of performance on emotional feedback perception to some extent. However, none of the feedback conditions improved affective-motivational outcomes independent of students’ performance.

论口语表达中的模糊性－－模糊语言研究之三

模糊性是非人工语言的本质特征。口语表达比起书面表达，模糊词语和模糊言语使用频率更高，更有效。口语表达中的模糊性，除了由客观事物的模糊性所决定之外，还在很大的程度上源于思维的模糊性，情感的模糊，言语表达的有限性。     

The Theory of Motivated Information Management and Posttraumatic Growth: Emerging Adults’ Uncertainty Management in Response to an Adverse Life Experience

This study tested the degree to which the uncertainty management process that emerging adults go through following an adverse event predicts their perceptions of posttraumatic growth. Participants included 215 emerging adults who had experienced an adverse life event within the past year. Overall, the results largely supported the theory of motivated information management, as uncertainty discrepancies positively predicted negative emotions about the adverse event, which in turn predicted outcome expectancies, but not efficacy assessments. Outcome expectancies were predictive of efficacy assessments, which in turn were predictive of a willingness to seek information about the event from a parent. Collectively, uncertainty management behaviors predicted posttraumatic growth and included significant indirect effects for uncertainty discrepancies through communication and target efficacy, respectively.     

The role of elevation in moral judgment

ABSTRACT

Elevation is the emotion elicited by witnessing acts of moral beauty and may be framed as the opposite of disgust. Two studies investigated the role of elevation in moral judgment and its relation to disgust. In Study 1 it was investigated whether elevation can attenuate the effects of disgust on moral transgression judgments. Participants were either induced to experience disgust (by giving them a bitter beverage), or to experience disgust and elevation simultaneously (by video induction). No effects of either emotion on moral transgression judgments were found. In Study 2 the nature of causal connectedness between elevation and moral virtue judgments was investigated by testing whether elevation amplifies moral virtue judgments. It was found that participants judged morally good acts as being more morally good when being elevated, suggesting that there is a bidirectional causal link between elevation and judgments of moral virtue.
