The relationships between social participatory roles and cognitive engagement levels in online discussions

Understanding the relationship between social interaction patterns and cognitive engagement levels has critical implications on collaborative learning theory, pedagogy, and technology. This study used a multi-method approach to examine the relationship between students' social participatory roles and cognitive engagement levels within asynchronous online discussions. Results showed that students' social participatory role was a critical indicator of cognitive engagement level. Socially active students made more cognitive contributions to knowledge inquiry and knowledge construction. But there were exceptions: after taking leadership roles (i.e., discussion designers and facilitators), some students moved from peripheral participation to active participation. Second, there was a progressive development process: individual students' deep-level knowledge inquiry could trigger peer interaction, which could further advance group knowledge construction. Third, students had a tendency to keeping social-cognitive engagement patterns throughout discussions. Based on the result, this study proposed implications for collaborative learning theory, pedagogy support, and tool development.     

Interventions supporting baccalaureate achievement of Latinx STEM students matriculating at 2-year institutions: A systematic review

Numerous national reports have identified the importance of significantly improving pathways that begin with Latinx students enrolling in 2-year institutions and ultimately completing baccalaureate degrees in STEM fields at 4-year institutions. Many programs using multiple interventions have been designed, implemented, and studied to achieve this goal. To synthesize what has been learned from studies of these programs, this article presents a systematic review of published studies of programs designed to support Latinx student success in 2-year institutions and successful transfer to 4-year institutions, particularly for STEM majors. A total of 49 quantitative, 9 qualitative, and 16 mixed-methods studies published as reports, articles, or dissertations since 1980 were identified that met the criteria for the review. Studies covered a wide range of interventions, including mentoring, counseling, advising, study groups, tutoring, scholarships, orientations, career services, undergraduate research, articulation agreements, and transfer programs. Individually, these studies report positive influences on student success outcomes, including 2- and 4-year graduation, transfer to a 4-year institution, retention, and success in individual courses. However, the number of qualifying studies was surprisingly small, considering the importance of improving success of Latinx students and the length of time during which the problem has been repeatedly emphasized. Few interventions have been undertaken from explicitly assets-based perspectives or theoretical frameworks. The lack of explicit frameworks underlying interventions—combined with a sole/primary focus on students—suggests many interventions were approached from a deficit-based perspective. Further, the study found no pattern of replication studies that might confirm effectiveness of potentially promising interventions. Based on our analysis of evaluations presented in the studies, it does not appear that the research community has developed agreed-upon methods to evaluate commonly agreed-upon outcomes. Finally, no intervention has been sufficiently supported that widespread implementation could be recommended.

关联理论下的言语幽默探析

文章从关联理论的角度研究言语幽默,它对幽默话语具有极强的解释力。幽默是说话人表达信息时在恪守最佳关联原则和＂关联理论＂为会话幽默的推导下所提供的理解模式,妙语语境效果小,关联性小,是言语幽默效果产生及理解的关键。     

城市生活垃圾产量的组合预测

引入一种新的预测垃圾产量的方法——组合预测方法,该法能够综合利用不同预测方法提供的信息提高预测精度。结合厦门市1996～2008年的垃圾产量,分析不同预测方法的预测精度,并预测5年后的垃圾产量。通过研究发现:单一预测模型中,线性回归法和年增长率法的预测结果偏小,误差较大,灰色理论GM(1,1)的预测结果偏大,误差较小,基本在10%以内;组合预测模型的预测精度高于单一预测模型;厦门市城市生活垃圾年平均增长率约为10%,低于国民生产总值和社会消费品零售总额年平均增长率,高于城镇居民消费性支出年平均增长率。

张爱玲小说标题意象分析

张爱玲善于将各种自然意象、社会意象融入到小说标题中,赋予这些意象独特的主观感受,表现自己对生命意义的体悟。张爱玲小说标题的意象,高度凝练,隽永深刻,具有哲理性、象征性、求解性、多义性,以及现代主义的荒诞性。意象的成功运用为张爱玲小说悲剧性主题的表达提供了物质基础,奠定了苍凉黯淡的基调。
