This study explored the influence of an excessively challenging reading task on middle school students’ motivation, attributions for failure, and persistence. In particular, the authors considered the possibility that relative topic interest might function as a buffer against the negative outcomes of excessive challenge. Students ranging from 10 to 14 years of age read a passage that was well beyond their current reading ability under 2 matched experimental conditions: high relative topic interest and low relative topic interest. Higher relative interest in the story topic buffered some of the negative influences of excessive challenge, sustaining interest/enjoyment of the task, and was related to fewer attributions for difficulty to any cause and persistence with the task.  相似文献

Wilson et al.'s (1998) revision of politeness theory has been applied to requesting, refusing and relational development, finding that different types of face threat are present in an interaction depending on the interaction goals. This investigation seeks to extend Wilson et al.'s (1998) work by determining how threats to a speaker's and hearer's face needs influence a requester's desire to persist and use of persuasion and forgiving statements after refusal. Results indicate that refusals creating greater threat to the positive and negative face needs of requesters yield greater desire to persist and use of persuasion statements. Specific face threats did not appear to be related to use of forgiving statements.  相似文献

Beliefs serve as an adaptation that helps teachers organize their teaching world. Little is known, however, about how beliefs change and serve to help retain and sustain teachers, particularly for beginning teachers who are most likely to leave teaching. This study explores teachers' beliefs about students in the US (N = 67) and if these beliefs change during the first five years of teaching. Results indicate that teachers hold beliefs about students that capture pride and participation. Over time, these beliefs become more positive. Implications for teacher education and policy are discussed.  相似文献

Early withdrawal from college can present problems for students and educators. In an effort to broaden our understanding of factors associated with students' persistence in higher education, we examined the ability of variables from Social Cognitive Career Theory assessed before college and during students' second semester to predict first-year college persistence. Hierarchical logistic regression analyses revealed that academic ability/past performance and social-cognitive variables assessed during students' second semester were significant predictors of first-year persistence. However, academic ability/past performance was the only precollege predictor significantly related to persistence. Implications for institutional assessment, intervention, and research are presented.  相似文献

《西游记》中唐僧、悟空、八戒、沙僧各自代表了一个人的几个不同方面。根据小说创作的思想文化背景、作者的创作意图和作品的客观效果,再结合小说所塑造的人物形象间的矛盾冲突,我们可以得出小说的主要精神乃是通过描写师徒四人西天取经的故事,写出了一个人悟道修真、修持心性的心路历程,即一个人以理想、信念为支柱,以认识、行动为手段,战胜内心欲念,抵制外界引诱,克服面对困难产生的犹豫、退缩情绪,最终达到“即心即佛”的境界,这样一个内部思想矛盾斗争的过程。  相似文献

以Keep为例,依托技术接受模型(TAM),通过发放问卷随机抽取400名被试,采用相关分析和回归分析检验假设模型。探索锻炼承诺在运动社交平台和锻炼坚持性之间的中介解释机制。结果发现互动性能够通过自我效能、满意度、锻炼动机预测锻炼承诺,而锻炼承诺能够预测大学生的锻炼坚持性。研究为互动性促进大学生坚持锻炼提供了一定的理论依据,并为运动社交平台的设计提供了可借鉴的参考。  相似文献

The current literature review explores the factors that contribute to academic persistence for adult learners. The aim of the study is to identify current research‐based strategies aimed at supporting learner persistence, particularly for low‐skilled adults. Elements of three theoretical frameworks, namely, expectancy‐value theory (EVT), goal theory (GT) and self‐determination theory (SDT) are conceptualised in a new, melded cognitive model to explain better the constructs that contribute to academic persistence. These theories are used to frame and explain the challenges that adult learners face when returning to school and to understand better the psychosocial demands on adult learners, based on social cognitive theory. This study is particularly significant in the light of current national attention directed towards redesigning adult basic education programmes to include more workforce development and strategies aimed at accelerating the progress of adult learners through basic skills and into post‐secondary education and/or career training. Questions guiding the current study include identifying research‐based strategies that instructors can use, and elements of programme design that support student persistence.  相似文献
