The aspects and ability groups in which little fish perform worse than big fish: Examining the big-fish-little-pond effect in the context of school tracking

The present study focused on junior high-school graduates who were equally able but attended different-rank high schools, comparing their academic self-concept, school adjustment, and academic achievement upon the completion of senior high school. An overall-school analysis was used to replicate previous findings, and an adjacent-school comparison was conducted to compare the performance of students at the bottom of a higher track and their similar-ability counterparts at the top of a lower track. The results indicated that the big-fish-little-pond effect (BFLPE) affects the academic self-concept and school adjustment of certain students, but not their academic achievement. Furthermore, the BFLPE was present between the bottom students of the first-ranked school and the top students of the second-ranked school, but not between the bottom students of the second-ranked school and the top students of the third-ranked school. The obtained results indicate that the BFLPE may not necessarily be associated with cognitive outcomes such as academic achievement and tracking contexts with less contrasting groups.     

Left-behind children: teachers’ perceptions of family-school relations in rural China

Large-scale rural-urban migration in China has left rural schools with large proportions of left-behind children whose parents are away working in the city. This has a huge impact on family-school relations and poses a burden on teachers. This study draws on 42 interviews with teachers working in two rural schools. This article argues that teachers’ negative narratives about antagonistic family-school relations are driven by the gaps between their culturally embedded traditional models of family-school relations and the reality, with implications for the expanded role of schools and that of grandparents as caregivers. This article further discusses the implications of these findings for rural schools and draws heavily on Western models of family-school relations in a comparative perspective.     

Impacts of flipped classrooms with peer assessment on students’ effectiveness of playing musical instruments – taking amateur erhu learners as an example

ABSTRACT

Amateur musical instrument learners are usually taught in a one-to-many learning mode owing to the cost consideration; therefore, it is difficult for the teacher to address individual students’ problems. This results in a lack of knowledge internalization. The flipped classroom enables the teacher to have more in-class time to interact with individual students. However, when the teacher guides a learner in the flipped class, the other learners usually practice on their own rather than engaging in critical thinking or reflective thinking activities. Therefore, this study uses the peer assessment strategy to increase the effectiveness of musical instrument flipped teaching. However, conventional peer assessment flipped teaching (CPA) has some disadvantages. So, we present another method in which the peer assessment is performed by online video sharing (VSPA). The VSPA method can further extend the learning time until after class. It lets teachers have more time to solve the problems of individual students. Besides, it can reduce the students’ nervousness. The experimental results showed that both of the two teaching modes can help progression, but there is no significant difference in the learning effectiveness. As for learning preference, we found that the learners preferred CPA to VSPA.     

Relationships between childhood abuse and neglect experience and HIV risk behaviors among methadone treatment drop-outs

OBJECTIVE: The purpose of this study was to examine the relationships between childhood abuse/neglect experiences (sexual abuse, physical abuse, emotional abuse, and child neglect) and adult life functioning among Methadone Maintenance Treatment Program (MMTP) drop-outs. METHOD: 432 subjects who dropped out of MMTP were recruited in New York City in 1997-1999. Adult life functioning was measured by HIV drug and sex risk behaviors, Addiction Severity Index (ASI) composite scores, and depression. The chi(2) tests, t tests, correlation, and multiple logistic regressions were performed to examine the relationships between abuse experiences and adult life functioning. RESULTS: The prevalence of child abuse/neglect history was high among MMTP drop-outs: sexual abuse-36%; physical abuse-60%; emotional abuse-57%; child physical neglect-66%; all four experiences-25%. As assessed via ASI composite scores, those who had been abused in childhood had significantly more medical, legal, relationship, and psychological problems than those who had not. Overall, several significant associations were found between the abuse experiences and HIV risk behaviors. Those who had experienced child neglect were more likely to be HIV positive. In multivariate analyses, childhood physical abuse was a significant predictor of having multiple sex partners while depression was significantly related to injection drug use in adulthood (p<.05). There were trends for the relationships between childhood sexual abuse and HIV sex risk behavior (p<.10) and between gender and injection drug use (p<.10). CONCLUSIONS: The findings support a need for drug treatment programs that include specialized therapies for those who suffered childhood abuse and neglect experiences.

How flexible gender identities give young women advantages in China’s new economy

ABSTRACT

In this article, we examine how a cohort of urban youth born under China’s one-child policy have developed flexible gender identities through their childrearing aspirations and educational and occupational narratives, choices, and trajectories between 1999 and 2014. Drawing on surveys of 406 respondents conducted in 1999, 2012–2013, and 2013–2014, and interviews of 48 of those respondents in 2011–2014, we argue that our female research participants were more able to produce flexible gender identities than their male counterparts, and that China’s new market economy increasingly rewards youth who are flexible enough to adjust to rapidly changing circumstances, an approach more compatible with the flexible gender identities produced by young women than the more rigid gender identities produced by young men.     

Using mobile devices to enhance the interactive learning for spatial geometry

The purpose of this research is to develop a hands-on spatial geometry learning system to facilitate the learning of geometry. The development of this system was based on Duval's four critical elements of geometric learning: perceptual apprehension, sequential apprehension, operative apprehension, and discursive apprehension. The system offers support to high school students in the process of spatial geometry problem-solving. It provides a hands-on approach for manipulating spatial figures, thereby developing the students' visualization skills and ability to conceptualize images. The experiment comprised a total of 58 participants from different classes with the experimental group using the proposed learning system, whereas the control group using the traditional pencil-and-paper approach. The study investigated the effects of the hands-on system on the perceptual, sequential, and operative apprehension, and on overall spatial geometry scores and learning attitude. The results indicated improvements on effective learning and a higher level of sequential, operative apprehension, and overall spatial geometry scores from the experimental group.     

Effects of concept-mapping-based interactive e-books on active and reflective-style students’ learning performances in junior high school law courses

Researchers have pointed out that interactive e-books have rich content and interactive features which can promote students’ learning interest. However, researchers have also indicated the need to integrate effective learning supports or tools to help students organize what they have learned so as to increase their learning performance, in particular, for abstract and complex learning content such as that in law courses. In this study, a concept-mapping-based interactive e-book learning mode was proposed. To understand the learning effects, a quasi-experimental design was used to compare the learning achievement and motivation of the students learning with the proposed approach (experimental group) and those learning with conventional interactive e-books (control group) in a junior high school fundamental law course. Meanwhile, the learning achievement and motivation of the students with different learning styles were also explored. The experimental results showed that the proposed approach significantly improved the students’ learning achievement, especially for the active-style students; moreover, it was found that the lead-in of concept mapping did not affect the students’ learning motivation. Factors that might affect the students’ learning achievement and motivation with the concept-mapping-based interactive e-book approach are discussed accordingly.     

Investigation of newly developed added damping and stiffness device with low yield strength steel

Energy dissipators, isolated-resistant and specific structural forms for earthquake resistance are popular topics in the research to improve shock-resistance. In this work, experimental methods were used to investigate the property of low yield strength steel. Carbon content in LYS material is lower than that in other steels; the ultimate stress is three times the yield stress. The ultimate elongation rate is about 62% and the ductility is 2–3 times that of A36 steel. In order to overcome some defects of ordinary use metallic dampers, the mechanical characteristic of low yield strength steel is used to develop added damping and stiffness for rhombic steel plate absorber. Test of the energy dissipation behavior for this newly developed device indicated that LYS could stably dissipate or absorb the input energy of earthquake. Then, the analytical model for the hysteretic behavior of this new device is proposed. Comparison of experimental data and numerical simulation results showed that this analytical model is suitable for simulating the hysteretic energy behavior of this new device.     

Student Perceptions of Autonomy-Supportive Instructional Interactions in the Middle Grades

Autonomy support in classrooms is believed to coordinate students' inner motivational resources in ways that enhance student engagement (e.g., Jang, Kim, &; Reeve, 2012 Jang, H., Kim, E. J., &; Reeve, J. (2012). Longitudinal test of self-determination theory's motivation mediation model in a naturally occurring classroom context. Journal of Educational Psychology, 104(4), 1175–1188. Retrieved from http://dx.doi.org/10.1037/a0028089[Crossref], [Web of Science ®] , [Google Scholar]). Yet, to our knowledge, no study has investigated student-generated interpretations of the motivational significance of their teachers' autonomy-supportive practices. Interpretations gathered from students' responses to video clips of their own teacher were studied with a diverse sample of students (N = 59, 50.8% male, 64.4% African American) in six urban classrooms from fourth- to eighth-grade class sections. Through this method of cued video response, we explore whether or not students experience the significance of autonomy-supportive instructional events or interactions as motivational theory predicts. Our results suggest that consideration of the social and relational features of the classrooms within which teachers enact autonomy support may identify influential contextual factors relevant to how and why autonomy support is linked to positive outcomes.
