CTE Policy Past,Present, and Future: Driving Forces Behind the Evolution of Federal Priorities

Federal legislation has driven and been receptive to the vision of a rigorous, relevant career and technical education (CTE) system integrated with academics and aligned across middle school, secondary school, and postsecondary education. This article uses a social policy analysis approach to trace the history of federal CTE policy throughout the 20th century and the beginning of the 21st century. Through this overview, we demonstrate how federal CTE policy has repeatedly evolved and responded to changing economic and social needs, while also incorporating policy flexibility that has led to variation in program implementation on the state and local levels.     

Exploring the experience of ten Australian Honours students

Honours study is viewed as a transition from undergraduate to postgraduate study and/or to enhanced career prospects. In Australia, Honours is usually an adjunct to the standard undergraduate degree. This paper provides an ethnographic study of 10 Australian Honours students. Seeing their experience through their reflections, in their own voices, reveals that Honours may be more than transitional – these students were transformed personally. Such emotionally charged transformations require academics to reflect on the best forms of support for Honours students.     

Mother–child joint writing in Chinese kindergarteners: metalinguistic awareness,maternal mediation and literacy acquisition

The present study examined the relations of Chinese word reading and writing to both maternal mediation of writing and a number of metalinguistic and cognitive skills in 63 Hong Kong Chinese kindergarteners. The whole process of maternal mediation of writing, in which mothers individually facilitated their children's writing of 12 two‐character words in their own ways, was videotaped. This study replicated and extended previous work on the cognitive strategies mothers use to help children in writing Chinese words. Mothers' typical mediation strategies were positively and significantly associated with both children's independent word reading and writing. In addition, maternal mediation of writing was uniquely associated with Chinese word reading, but not word writing, even with metalinguistic and cognitive skills, including phonological awareness, morphological awareness, orthographic processing and visual knowledge, statistically controlled. Findings underscore the importance of mothers' early scaffolding in facilitating children's literacy acquisition.     

Individualism-collectivism among Americans, Turks and Turkish immigrants to the U.S.

Whether immigrants to the U.S. from collectivist cultures will adopt American individualist values is an important question at the intersection of theories on acculturation and individualism/collectivism. According to the assimilation hypothesis, Turkish immigrants to the U.S. should become more individualistic with increasing length of stay. Alternatively, the immigrant interdependence hypothesis proposes that the exigencies of immigration require retaining or increasing collectivist values and behaviors, especially the willingness to rely on others. Measures of individualism and collectivism were obtained from Turkish immigrants to the U.S., Turks residing in Istanbul, and residents of Boston. Bostonians and Istanbul residents differed primarily on vertical collectivism, which is the tendency to subordinate ones own goals to those of in-group authority figures. Immigrants’ values did not change with increasing length of stay in the U.S., refuting the assimilation hypothesis. When immigrants were compared to non-immigrants, immigrants endorsed stronger horizontal and vertical collectivism and more desire to both give and receive, consistent with the immigrant interdependence hypothesis. However, this hypothesis was not uniformly supported. Compared to non-immigrants, immigrants reported more self-reliance with competition, and more internal locus of control, indicating a sense of agency and responsibility. Findings are consistent with the view that immigrants adjust in complex ways to their new society, and may have different temperaments than non-immigrants.     

论艺术教育的意义与价值

社会上存在很多对艺术教育的迷思,比如,艺术与教育的关系是什么?艺术是否可教?艺术完全是灵感的产物吗?艺术是否值得被教?艺术教育的作用是什么?符号理论可以表明艺术教育的可行性及价值。我们不应该将艺术仅仅视为达成某一具体目的的手段,而应该将其既看作目的,又视为手段。艺术完全是灵感的产物这一假设是没有根据的,学生的感觉回应和情感反应可以被教育,艺术教育是可能的,也是有价值的。     

Fictitious Academic Expertise and Processing Resources

A previous study showed that pairs of students interacting in a second language produced more words when they were assigned a fictitious expert position in a specific competence dimension than when they were assigned a nonexpert position. It has also been shown that the usual level of expertise has an impact on the assigned fictitious expertise effect. The present study was designed to determine whether the processing capacity allotted to the current task could partly determine performance. A given position of expertise may demand a large or small attentional capacity. Two experiments were conducted using a dual-task paradigm. As expected, the different expertise positions led to different reaction times on the secondary task. The second experiment showed that the impact of assigning a position of expertise to students depends on their usual academic standing. This study supports the idea that in interactive situations, performance variations as a function of the expertise position can be partially explained by differences in the processing resources allocated to the task. Implications for teaching are discussed.     

Effects of a Mindfulness-Based Intervention on the Perception of Basic Psychological Need Satisfaction among Special Education Students

Mindfulness-Based Interventions (MBIs) have been increasingly implemented in schools to foster better emotional regulation skills for students with special education needs such as learning disabilities (LDs). This pilot study aimed to evaluate the impact of a MBI on the need satisfaction of elementary students with severe LDs. A prospective quasi-experimental design involving one group and two time points was employed. A sample of 14 elementary school students from a severe LDs special education class participated in this project. Repeated-measures ANOVAs were conducted and revealed a significant reduction in need satisfaction, with a large effect size (η² = .35). Contrary to our hypothesis, the MBI appeared to be negatively related to need satisfaction among participants. These results indicate that MBIs could be linked with better self-evaluation skills in students with severe LDs, which, in turn, may change (or increase the accuracy of) the perception that children have of their own need satisfaction.
