Women teachers in Hong Kong: stories of changing gendered identities

In a time of mass schooling in most parts of the world, the discourse of the “woman primary teacher” is often the subject of discourse. Yet most stories of these women teachers emerge from other (Western) contexts, with little known about how changing education processes affect the gendered identities of women in other cultural settings. This paper explores how women teachers negotiate their gendered identities in Hong Kong, where modernization has already mingled with the indigenous Chinese culture. It provides the stories of four Chinese women teachers as they engage in ongoing construction and negotiations of gendered identities over their life histories in Hong Kong. All are ethnically Chinese, of different ages and at different stages of their personal and professional lives, and all have grown up in Hong Kong. A framework of post-colonial concepts of hybridity and border crossing helps to suggest how identity resources develop in relation to a range of contemporary practices which are experienced as both pressures and opportunities. These Chinese women teachers' identities are seen to be complex, fluid and multi-faceted, continually under construction in their daily lives, with changes experienced in both work and family settings.

Direction dependence of displacement time for two-fluid electroosmotic flow

Electroosmotic flow that involves one fluid displacing another fluid is commonly encountered in various microfludic applications and experiments, for example, current monitoring technique to determine zeta potential of microchannel. There is experimentally observed anomaly in such flow, namely, the displacement time is flow direction dependent, i.e., it depends if it is a high concentration fluid displacing a low concentration fluid, or vice versa. Thus, this investigation focuses on the displacement flow of two fluids with various concentration differences. The displacement time was determined experimentally with current monitoring method. It is concluded that the time required for a high concentration solution to displace a low concentration solution is smaller than the time required for a low concentration solution to displace a high concentration solution. The percentage displacement time difference increases with increasing concentration difference and independent of the length or width of the channel and the voltage applied. Hitherto, no theoretical analysis or numerical simulation has been conducted to explain this phenomenon. A numerical model based on finite element method was developed to explain the experimental observations. Simulations showed that the velocity profile and ion distribution deviate significantly from a single fluid electroosmotic flow. The distortion of ion distribution near the electrical double layer is responsible for the displacement time difference for the two different flow directions. The trends obtained from simulations agree with the experimental findings.     

CLASSROOM QUALITY AND STUDENT BEHAVIOR TRAJECTORIES IN ELEMENTARY SCHOOL

Student behavioral concerns are a top priority for school psychologists. This project took an ecological systems perspective by examining the contribution of students’ initial externalizing and internalizing behaviors and the quality of their classroom environments to their behavioral outcomes across one school year. Participants included 322 elementary students and their 32 teachers. Results suggested that externalizing and internalizing behaviors were stable over time. However, the correlation between fall and spring internalizing behavior was accentuated if students also had high externalizing behavior in the fall. Poor spring behavioral engagement was predicted by students’ fall internalizing (but not externalizing) behavior. Importantly, classrooms high in emotional support attenuated the stability of students’ internalizing behavior. In addition, students’ fall externalizing behavior appeared to be associated with reduced spring internalizing behavior in classrooms high in emotional support or classroom organization. Findings underscore the importance of considering both student‐ and classroom‐level factors when predicting elementary students’ behavioral outcomes.     

CLASSROOM VICTIMIZATION: CONSEQUENCES FOR SOCIAL AND ACADEMIC ADJUSTMENT IN ELEMENTARY SCHOOL

Peer victimization is a well‐established risk factor for children's adjustment, but it has rarely been studied as a feature of classroom climate. This study examines the consequences of classroom victimization for children's social and academic adjustment. Classroom victimization, social functioning, and academic adjustment were assessed in two subsamples taken from a full sample of 523 children nested in 28 classrooms, followed over the course of a school year. Results from a subsample of 213 students suggested that higher classroom levels of victimization predicted attenuated growth in children's reading achievement as well as greater stability of reading achievement over the course of the year. Results from a subsample of 490 children suggested that lower levels of classroom victimization predicted reduced stability of peer social preference and mitigated the trajectory between children's externalizing behavior and poor social preference. Implications for prevention of and interventions targeting peer victimization are discussed.     

Investigating the effectiveness of three-dimensionally printed anatomical models compared with plastinated human specimens in learning cardiac and neck anatomy: A randomized crossover study

Three-dimensional printing (3DP) technology has been increasingly applied in health profession education. Yet, 3DP anatomical models compared with the plastinated specimens as learning scaffolds are unclear. A randomized-controlled crossover study was used to evaluate the objective outcomes of 3DP models compared with the plastinated specimens through an introductory lecture and team study for learning relatively simple (cardiac) and complex (neck) anatomies. Given the novel multimaterial and multicolored 3DP models are replicas of the plastinated specimens, it is hypothesized that 3DP models have the same educational benefits to plastinated specimens. This study was conducted in two phases in which participants were randomly assigned to 3DP (n = 31) and plastinated cardiac groups (n = 32) in the first phase, whereas same groups (3DP, n = 15; plastinated, n = 18) used switched materials in the second phase for learning neck anatomy. The pretest, educational activities and posttest were conducted for each phase. Miller's framework was used to assess the cognitive outcomes. There was a significant improvement in students' baseline knowledge by 29.7% and 31.3% for Phase 1; 31.7% and 31.3% for Phase 2 plastinated and 3DP models. Posttest scores for cardiac (plastinated, 3DP mean ± SD: 57.0 ± 13.3 and 60.8 ± 13.6, P = 0.27) and neck (70.3 ± 15.6 and 68.3 ± 9.9, P = 0.68) phases showed no significant difference. In addition, no difference observed when cognitive domains compared for both cases. These results reflect that introductory lecture plus either the plastinated or 3DP modes were effective for learning cardiac and neck anatomy.
