How can students be taught to develop explanations for scientific phenomena on their own when their background knowledge is incomplete or poorly organized? Evidence from historical accounts of scientific discovery suggest that self-generated analogies—analogies produced by the learners themselves—are a tool by which individuals can generate, evaluate, and modify their own explanations. The central research questions for this study were: Can students use a series of self-generated analogies to bring about change in their understanding of a given scientific phenomenon, and what is the nature of the change in understanding? Participants were asked to create, apply, and modify their own analogies—as opposed to applying a specific analogy provided by an outsider—as a heuristic for constructing, evaluating, and modifying their own explanations for a given scientific phenomena. Nontrivial changes in explanation facilitated by the use of generative analogies were observed. Changes in understanding ranged from the emergence of new explanations to the raising of important questions about the nature of the phenomenon. 相似文献

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
