This study investigated the effects of dialogic parent–child reading in English on 51 Hong Kong kindergarteners learning English as a second language. Children were pre‐tested on nonverbal IQ, reading interest and receptive vocabulary, word reading and phonological awareness in both Chinese and English. They were then assigned randomly to one of three conditions involving different levels of parent–child interactions: dialogic reading (DR), typical reading (TR) or control. Though inter‐group comparisons showed nonsignificant interaction effects across time among the three groups, intra‐group gains across the 12‐week intervention suggested that parent–child reading could enhance English word reading skills, while dialogic reading could promote phonological awareness in both Chinese and English. These results highlight the potential benefits of English parent–child reading and dialogic reading on children learning English as a second language, and the possibility of linguistic transfer from parent–child reading in English as a second language to Chinese as a first language. 相似文献

This experiment was designed to examine the instructional effectiveness and efficiency of organizational chunking and batched postquestions within the framework of an information-processing approach to learning and memory. The coding processes utilized by the content organization employed both encoding and retrieval aids to facilitate the acquisition, retention, and retrieval of the information to be learned. Major findings indicate that the chunked treatment resulted in a more efficient learning strategy than the conventional treatment; however, the chunked and conventional treatment, as different encoding strategies, did not produce significant differences in achievement on the performance task. Additionally, students receiving the intervening postquestion strategy took significantly less time in completing the performance measure than did those students who received the non-intervening postquestion treatment. 相似文献

Intrinsic motivation (IM) is an important predictor of children’s physical activity participation. The present 3-year longitudinal study examined changes in IM toward physical activity among a group of at-risk boys (N = 92) at a summer sports camp. Results showed the boys were intrinsically motivated in their first camp year, but their IM levels declined throughout 3 years of participation. This decline might be due to insufficient instructor support and repetitively scheduled activities at the camp. There were no ethnic differences in the initial IM mean scores or rates of IM change. Such homogeneity might be attributable to the boys’ similar demographic characteristics. Future research should identify possible causes of declined IM for camp coordinators and instructors to better design and implement sports and physical activities to sustain the boys’ IM. 相似文献

The need for interdisciplinary graduate training programs which prepare students to conceptualize the application of their research in clinical settings continues to grow. Though several programs have been cultivated to address this need, demand still outweighs supply. The following describes a curriculum developed with the intent of incorporating medical knowledge into a PhD graduate training program. Development of this Molecular Medicine program by the Cleveland Clinic Lerner College of Medicine in collaboration with Case Western Reserve University was funded by the Howard Hughes Medical Institute "Med into Grad" initiative. The core curriculum of this program begins with a foundation in Human Physiology and Disease course in which anatomy faculty introduce students to a basic overview of gross anatomy structure and function. This course is followed by five fundamental basic science courses, a composite course focusing on principles of clinical and translation research, a course on laboratory techniques and three, 12-week research rotations. In the second year of the program, students begin their dissertation research, complete their qualifying examination, and partake in an individually tailored Clinical Experience course. Interdisciplinary graduate programs like this provide another venue for faculty in anatomical sciences to help aspiring translational scientists relate basic science knowledge to human pathophysiology and health. 相似文献

A randomized prevention design was used to investigate a moderation effect in the association between a polymorphism in the SCL6A4 ( 5HTT ) gene at 5-HTTLPR and increases in youths' risk behavior initiation. Participation in the Strong African American Families (SAAF) program was hypothesized to attenuate the link between 5-HTTLPR status and risk behavior initiation. Youths ( N = 641, M age = 11.2 years) were assigned randomly to a SAAF or control condition. Risk behavior initiation across 29 months was linked positively with the 5-HTTLPR genotype and negatively with SAAF participation. Control youths at genetic risk initiated risk behavior at twice the rate of SAAF youths at genetic risk and youths not at genetic risk in either condition. 相似文献

The purpose of this investigation was to compare external work and net energy expenditure during a bout of repetitive stretch-shortening cycles between competitive and recreational long-distance runners. Participants were divided into either competitive or recreational runners based on their maximal oxygen consumption and self-reported 1600 m times. The stretch-shortening cycle involved a repetitive hopping protocol on a force plate while measuring oxygen consumption and lactate accumulation for a total of 10 min. External work and net energy expenditure were calculated for 3 min after steady state was achieved and the ratio between these variables was utilised as an index of mechanical efficiency. Lower extremity stiffness was calculated during this interval as well. Net energy expenditure was significantly lower in competitive runners (152.6 ± 33.3 kJ) in comparison to recreational runners (200.6 ± 41.4 kJ) (P = 0.02) given similar amounts of external work performed in both groups (competitive runners = 65.6 ± 20.1 kJ, recreational runners = 68.8 ± 12.1 kJ) (P = 0.67). Index of mechanical efficiency was significantly different between competitive runners (43.2 ± 9.0%) and recreational runners (34.8 ± 5.3%) (P = 0.03). No significant differences were found in lower extremity stiffness (P = 0.64). Competitive distance runners can perform similar levels of external work with lower net energy expenditure and thus a higher index of mechanical efficiency during repetitive stretch-shortening cycles in comparison to recreational runners with similar values of lower extremity stiffness. This ability could possibly be due differences in muscle–tendon length changes, muscle pre-activation, cross-bridge potentiation and short-latency reflex responses as a result of training which should be considered for future investigation. 相似文献
