We investigated the influence of self-efficacy beliefs and working memory capacity on mathematical problem-solving performance, response time, and efficiency (i.e., the ratio of problems solved correctly to time). Students completed a letter-recoding task (Experiment 1) or an operation span task (Experiment 2), rated their self-efficacy for solving mental multiplication problems, and then solved similar problems of varying complexity. We tested the motivational efficiency hypothesis, which predicted that motivational beliefs, such as self-efficacy, increase problem-solving efficiency through focused effort and strategy use. Experiments 1 and 2 reported a significant effect for self-efficacy on problem-solving performance and efficiency, but limited effects for time. A self-efficacy by working memory interaction occurred in Experiment 1, suggesting self-efficacy is beneficial as demands on working memory increase. These findings suggested that self-efficacy increased problem-solving efficiency through strategic performance rather than faster solution times, and were consistent with the motivational efficiency hypothesis. 相似文献

We examined whether making cause and effect relationships explicit with an adjunct display improves different facets of text
comprehension compared to a text only condition. In two experiments, participants read a text and then either studied a causal
diagram, studied a list, or reread the text. In both experiments, readers who studied the adjunct displays better recalled
the steps in the causal sequences, answered more problem-solving transfer items correctly, and answered more questions about
transitive relationships between causes and effects correctly than those who reread the text. These findings supported the
causal explication hypothesis, which states that adjunct displays improve comprehension of causal relationships by explicitly
representing a text’s causal structure, which helps the reader better comprehend causal relationships. 相似文献

In this qualitative study, the authors examined master's‐level counselor trainees' reactions to difficult dialogues in the classroom regarding racism, heterosexism/homophobia, and ableism over a 3‐year period. Using the Consensual Qualitative Research method as introduced by C. E. Hill, B. J. Thompson, and E. N. Williams (1997), the data analysis team analyzed narrative and reaction papers submitted during a didactic course on multiculturalism. Behavioral reactions were identified that form the basis for this study: denial, deflection, rationalization, intellectualization, principium, false envy, minimization, and benevolence. 相似文献

低氧诱导因子与乳腺癌转移 总被引:2,自引:0,他引:2

概肿瘤,特别是实体瘤,其内部微环境处于一种低氧或缺氧的状态,肿瘤的这种低氧微环境将诱导活化低氧诱导因子(HIF-1)信号通路。HIF-1信号通路在乳腺癌的转移中发挥着重要的作用。乳腺癌的转移涉及肿瘤细胞的浸润、进入血管、通过血液循环迁移、到达远端毛细血管内壁、穿透血管壁进入新的器官以及在新的部位形成转移灶等步骤,过程非常复杂。本文重点围绕 HIF-1在转移各个步骤中的作用进行综述。 相似文献
