This 2‐year longitudinal study examined both concurrent and longitudinal relations of a variety of reading‐related cognitive tasks and Chinese word reading and word dictation among 187 Hong Kong Chinese kindergarteners aged 4–6. Homophone awareness, visual skills and syllable awareness were all uniquely associated with Chinese word reading across time, with age, vocabulary knowledge and nonverbal IQ statistically controlled. Only visual skill and syllable deletion uniquely explained early Chinese word dictation, however. Results extend previous research on cognitive correlates of Chinese literacy and highlight the small but unique contribution of homophone awareness for early reading acquisition in Chinese.  相似文献

As part of a two-year, mixed methods study, the focus of this paper reports the qualitative findings that are related to nine beginning teachers' learning to teach with Information and Communication Technology (ICT) during their first year of teaching. It aims to explore how these teachers deepen their understanding performances of technology integration in their first year. They demonstrated consistent, varied perceptions, frequency and ways of using ICT for classroom teaching and learning from their initial teacher education to their first year teaching. They developed diverse understandings of technology integration from their own practice, and chose to play different roles, such as, follower, doer and emerging teacher leader for technology integration. Suggestions to schools on providing beginning teachers with ongoing technical and pedagogical support and capitalizing on their tech-savvy strengths are discussed.  相似文献

In this study, we attempt to investigate the potential effects of parents’ career interests on young adults’ career interests. Using a sample of 113 freshmen in Hong Kong, results indicated that after controlling for personality, gender, general mental abilities and emotional intelligence, some of the parents’ career interests were still related to the young adults’ respective career interests. For some types of interests, the extent of influences is found to be contingent on the gender of the respondents. Implications are discussed.  相似文献

A straight, non-sporulating, Gram-variable bacillus (HKU24T) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24T grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 °C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24T was non-motile and catalase-negative, but positive for alkaline phosphatase, β-glucosidase, and α-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24T occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24T groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.  相似文献

Empowering students to learn through ICT is seen as a way to address the growing awareness and demand for preparing students to effectively participate in the emerging global knowledge economy. It is believed that, in order to maintain competitiveness in a global economy, traditional classroom practices must be re-conceptualized in a way that enables students to engage themselves in knowledge building, to become more self-directed, and to assume greater autonomy and social responsibility over their own learning. In this article, we report a case study on the use of Tablet PCs to support teaching and learning in a primary school in Hong Kong, and provide insights into how schools can harness and capitalize on the opportunities offered by such emerging technologies.  相似文献

A survey research study was conducted with a sample of 100 secondary students from a local secondary school about the motives of cheating. The primary focus of this study was the interplay among variables of self-efficacy, peer influence and cheating. The results showed that students with low self-efficacy were more likely to cheat than those who perceived themselves as efficacious. It was further found that peers played a significant role in discouraging cheating by expressing disapproval and informing teachers of dishonest behaviour.  相似文献

The developmental trajectories of behavioral control and resiliency from early childhood to adolescence and their effects on early onset of substance use were examined. Behavioral control is the tendency to express or contain one's impulses and behaviors. Resiliency is the ability to adapt flexibly one's characteristic level of control in response to the environment. Study participants were 514 children of alcoholics and matched controls from a longitudinal community sample (Time 1 age in years: M =4.32, SD =0.89). Children with slower rates of increase in behavioral control were more likely to use alcohol and other drugs in adolescence. Children with higher initial levels of resiliency were less likely to begin using alcohol.  相似文献

Mainland China has a highly centralised curriculum development system. A study of two schools in northeast China, one in a rural area and the other in an urban area, indicates that the primary mathematics curriculum has been widely adopted by teachers at the classroom level. Feeling the intense pressure generated by the national mathematics Olympiad,1 1. The mathematics Olympiad is a type of ‘extracurricular’ activity that aims to promote students' interest and improve their ability in mathematics. Students participating in the competition are required to complete some challenging and non‐routine mathematical operations. The international mathematics Olympiad is held every year. In Mainland China, this competition is commonly organised at city, provincial and national level. Students who perform exceptionally well are exempted from the highly competitive national university entrance examinations for entry to universities View all notes teachers in the urban school tended to give more difficult mathematics problems to their students in the hope that above‐average students would perform well in the competition. In the rural school, the ability of students was more varied and generally lower. Teachers there worked very hard to push their students to meet the national requirements. The driving force behind this was the county‐wide public examination in which students' performance was taken as an indicator of teachers' competence. Teachers in both schools also have not taken effective steps to adapt the curriculum for students' individual differences. A comparison of the practices between the teachers in the two schools suggests that teachers' beliefs, their professional knowledge and skills shape their inclination and ability in curriculum adaptation and differentiation.  相似文献

This paper reports a technique for temperature-induced merging of droplets in a microchannel. The multiphase system consists of water droplet and oil as the dispersed phase and the carrying continuous phase. A resistive heater provides heating in a rectangular merging chamber. The temperature of the chamber is controlled by the voltage applied to the heater. The merging process of two neighboring droplets was investigated with different applied voltage, flow rate ratio between water and oil and total flowrate. Merging is found to be effective at high flow rate ratio, high temperature, and low total flowrate. The presented technique could be used for merging and mixing in droplet-based lab-on-a-chip platforms.  相似文献
